7 Final Report Framework and Action Plans for River Rehabilitation of Small Streams in the Brantas River Basin, East Java, Indonesia A. Activities 1. To produce a framework or guideline on integrated river rehabilitation project, with prioritised activities and anticipated output and potential outcomes. The Konto River is a tributary of the Brantas River. The Konto River Basin is divided into the Upper and Lower Reaches by the Selorejo Reservoir which formed in 1972 after completion of the dam. The upper watershed of the Konto River covers an area of 236 km 2 between four volcanic complexes which determine its natural setting. The altitute ranges from at the summit of Mt. Butak to 600 m above sea level (a.s.l) at the Selorejo Dam. In January February 2010, there have been several floods occurs in Konto River, i.e. on 14 January, 5 6 February and the last on 24 February The flood discharge on 24 February 2010 resulted casualties and damages, two peoples died (swept by flood), damaged bridge in Bendosari Village, cliff erosion, eight collapse check dam in Konto River, three houses damaged also paddy and agricultural field were inundated. This flood was also cause traffic jam in the route of Malang Kediri for two hours approximately. The Sereng river is a small tributary at the upper reach of Konto River. The river has length of 7.3 km approximately. The floods that happens in the Konto River was indicate the degradation of the watershed in the upper reach of Konto River. One of the efforts was improvement in the watershed area by encouraging public initiatives. In this Framework and Action Plans for River Rehabilitation of Small Streams in the Brantas River Basin, East Java, Indonesia to implementing structural and nonstructural measures. Structural and non-structural measures comprising : (1) Implementation of non structural measures, leading to preventing further catchment degradation (soil conservation) based on local community participation (e.g. bio-pores, land terracing, gully plug, regreening and/or re-forestation); (2) Construction or installation at least one eco-efficient modular/in-situ structure to reduce pollution flow into the stream and to improve water quality; and (3) Construction of at least one ecoefficient river protection to prevent river bed or river bank erosion. In the early of July 2010, the National Development Planning Agency (BAPPENAS) of Indonesia in cooperation with Swedish International Development Cooperation Agency (SIDA), Ramboll Natura, and Stockholm International Water Institute (SIWI), held an International Training on Integrated Water Resources Management (IWRM) Batch II Phase I in Selorejo, Malang. The training was attended by senior officials of River Basin Organizations (RBOs), NGOs and national news media. The training included a field trip to see some of the best practices of IWRM implementation in the surrounding area, especially in PJT I working area. One of the area that become destination site was this project area in Bendosari Village. Some of the training participant were interested to know the activities within this project and intend to implement it in their river basins. 1

8 Bendosari Green Village Concept The catchment area of Sereng River Basin is mostly located in the Bendosari Village, Pujon District, Malang Regency. Geographically, the Bendosari Village areas are mountainous and highland areas. The village has the area of approximately hectares which consist of 31 ha of settlement area and the rest are dry land and rainfed rice fields. The village is divided into five Dusun (sub village), namely: Dusun Cukal, Dusun Dadapan Wetan, Dusun Dadapan Kulon, Dusun Ngeprih and Dusun Tretes. The Bendosari Village has population of approximately 3,858 people and most of their occupations are mainly related to agriculture sector. The life philosophy of the people of Bendosari is reflected in their slogan stated in the Javanese Language "Rumangsa Melu Handarbeni, Rumangsa Melu Hangrukebi, Mulat Sariro Hangrasa Wani" which means thinking about how the village to be developed, advanced and independent to become self-sufficient villages. (Source: bendosari.wordpress.com). Jasa Tirta I Public Corporation in cooperation with the Bendosari Village Government has conducted many activities in order to promote the people s awareness on healthy and sustainable environment in the Bendosari Village under the initiative of promoting Green Village. The basic concept of Green Village here is to increase the environment sustainability through a master plan, consists of plan for watershed conservation by conducting reforestation, erosion control structures development and plan for environment improvement by developing wastewater treatment for cattle waste in the form biogas structure and healthy cage for animal husbandry. Due to the current flood that occured in early 2010, the watershed improvement activities was conducted more intensively by conducting re-greening activities, building check dams, and gully plugs. Those structures intended to prevent the erosion and sedimentation which flow into the river directly into the Selorejo Reservoir. Other activity is also conducted such as Community Based Bio-monitoring: Participative Water Quality Monitoring using Water Insect to increase the awareness of the society of the environment condition. This activity conducted in cooperation with Non Government Organization (NGO) namely ECOTON (Ecological Observation and Wetlands Conservation) organization. By implementing Green Village concept in the Bendosari Village, it is expected it will be the pilot project for other area especially in the Brantas River Basin especially in the upstream reach of the basin. 2. To implement structural and non-structural measures comprising: (1) Implementation of non structural measures, leading to preventing further catchment degradation (soil conservation) based on local community participation (e.g. bio-pores, land terracing, gully plug, regreening and/or re-forestation) a. Bio-pores (biopori) Bio-pores (biopori) is the water absorption method which is used to reduce the surface runoff and inundation effect by increasing the water infiltration capacity into the ground. This method was invented by Dr. Kamir R. Brata, a researcher of Bogor Institute of Agriculture (IPB). Bio-pores Infiltration Holes (Lubang Resapan Biopori / LRB) are appropriate technology and environmentally friendly of dealing with flooding. Actually, this technology is appropriate to be implemented in the urban area (such as Jakarta, Bogor etc.) due to the limited watershed area to infiltrate of water. 2

9 Concept of bio-pores is described as follows (source: http// Bio-pores holes are filled with organic waste. Organism in the bio-pores holes will make path which can encourage air circulation and accelerate the absorption and infiltration of surface runoff. The absorbed water will increase groundwater recharge. Organic waste will be changed to become natural fertilizer (compost). The effect of biopores to the environment can be explained below. Increasing the water absorption With usage of biopori hole, it is expected that the water absorption rate will increase minimally as large as the inner surface area of the hole. For illustration, if we make the hole with 10 cm of diameter and 100 cm depth, we can obtain extra absorption with volume area about 78,5 cm 2 or 78,5 x 10-4 m 2 approximately. With the activities of soil organism like worms in the biopori hole, the soil pore is expected to function as absorber and allow water to infiltrate. The combination of absorption areas from the biopori holes are anticipated to increase the water absorption and to minimizes the water runoff. Converting organic trash to compost Biopori hole is activated by filling the organic trash inside it. The organic trash is the source of energy for soil organism in the decomposition process. The result of this process is known as compost. With its function, biopori hole not only functioned as the absorption medium but is also the source of compost. It could be harvested in a period of time and used as the organic fertilizer. Utilizing the soil organism and roots As mentioned before the biopori hole will be activated by the soil organism. The activities of soil organism and roots will increase the soil porosity allowing better flow of water through the soil. Without human intervention this step is not available for the organism activities. The effect on the environment is to reduce runoff and reduce the use of inorganic fertilizer. Organic Waste Composting Process Formed from land organism activity Figure 1 Example of Bio-pores (Source : desainlansekap.wordpress.com & oasezam.wordpress.com) 3

10 b. Land terracing In agriculture, a terrace is a leveled section of a steep cultivated area, designed as a method of soil conservation to slow or prevent the rapid surface runoff. Often such land is formed into multiple terraces, giving a stepped appearance. This form of land use is prevalent in many countries, and is used for crops requiring a lot of water, such as rice. Terraces are also easier for both mechanical and manual sowing and harvesting than a steep slope would be. Terracing slows down the velocity of surface runoff and therefore allowed more run-off of water to infiltrate into the soil, hence it reduces erosion (Department of Forestry, Government of Indonesia). Figure 2 Example of land terracing in Indonesia (Source : & sahabatsiswa.wordpress.com) c. Gully plug Gully plug is a civil enginering technique of soil conservation for controlling surface water runoff through the rigs by establishing gully across the stream with stones (wood or bamboo) wrapped. Gully plugs can be defined as stones (wood or bamboo) placed across gullies or valleys, so as to capture nutrients, silt and moisture. Stones are often embedded into the upper surface of spillway aprons and wells to provide support for the next layer. The principle is to capture runoff from the catchment area, thus transferring low rainfall into utilizable soil moisture, and to prevent soil erosion. Slowing of the flow of water helps in settling down rich organic soil. A well maintained gully plug creates a flat, fertile and moist field, where high value crops and trees can be grown (Pretty Jules N, 1995). In many areas where gully plugs were built, agricultural production has increased, and farmers have shifted to high value crops. Examples of benefits of gully plugs are clearly visible in many developing countries such as India, Pakistan, Chad and Ethiopian (Pretty Jules N, 1995). The benefits of gully plug development are: To reduce land destruction caused by surface water runoff. To prevent of expansion of land destruction by widening of gullies. To control erosion and water run off from up hill to the downstream area. To improve watershed management. Gully plug is suitable for location with : 4

11 land slope of more than 30% critical areas (area that has reduced its function) catchment reservoir region with maximum 10 ha wide and deep of the gully maximum of 3x3 m length of the gully approximately 250 m slope of the gully max 5% Figure 3 Example of Gully Plug material using stones in India and United States (Source : & forthodreveg.tamu.edu) In several countries, bamboos can be used as the material of gully plug. Gully plugs construction of plaited bamboo materials that are set across the line of erosion. Bamboo plugs are constructed from upstream to downstream with distance interval of 0.5 m and with the height of 300 m. The bamboos were fitted together and tied with galvanized wire. Figure 4 Example of gully plug material using bamboo in Indonesia (Source : PJT I) d. Regreening (afforestation) and reforestation The purposes of afforestation and reforestation are to rehabilitate and to improve critical land conditions outside forest area through planting in order to improve its function for water management and production as well as to maintain and to improve land use. Afforestation activities such as establishment of private forest, is conducted by planting on bare land or in home gardens outside the forest areas with hardwood tree species, Multi Purpose Trees Species (MPTS), and/or horticulture trees. The aim of this program is to get optimal land cover for controlling critical lands, producing fuel wood and timber for local people, conserving lands, and improving micro-climate, water management and environment. 5

12 Reforestation or rehabilitation of protected forests is aimed to restore protection to forest area within watershed which is conducted through local people parcipatory. The main activities are planting the particular critical protection forest with specific tree species that provide benefits to the local communities, and to harmonize between forest function and people needs. Figure 5 Examples of Regreening (afforestation) & Reforestation activities in the Brantas River Basin (Source : PJT I) (2) Construction or installation of at least one eco-efficient modular/insitu structure to reduce pollution flow into the stream and to improve water quality Riverbank protection (revetment) is a structure placed on the surface of the slope of riverbank or levees in order to improve its stability and prevent landslides which can lead to collapse of river banks and/or leeves into the river. Riverbank protection (revetment) can be made from woven bamboo that is placed on both sides of the river banks. Figure 6 Examples of river bank protection (revetment) (Source : PJT I) (3) Construction of at least one eco-efficient river protection to prevent river bed or river bank erosion 6

13 The land conservation methods that had been used at that location was inadequate, causing continuous problems of land degradation which promote sediment erosion into the river. Therefore an environmentally friendly and economical protection measure should be developed to reduce the rate of erosion and to minimize the volume of sediment entering into the river. The river is a drainage channel that is formed naturally. However, according to the nature and form of the river in the upstream region with the narrow dimension, the steep slope of the river and a large flow rate caused the riverbed degradation and river banks erosion. Eco-efficient development of sustainable infrastructure aims to improve the quantity and quality of the river flow, with minimal waste of natural resources and within the stability and capacity of the environment carrying capacity. A drop structure is a structure which made from stone, bamboo or wood and compacted grass (gebalan rumput) that can reduce the energy of the water surface flow in an area having different height. A drop structure is needed if the slope of the bottom surface of the river is too steep. It is usually necessary to build a series of drop structures to maintain the river slope. The construction of drop structure consist of bamboo which is plugged in the bottom of the riverbed with the distance interval of 100 cm. The upper part of the structure is constructed with increments of bamboo in transverse position. The increments of bamboo and bamboo ori is woven with galvanized wire as reinforcement. In the lower part, the bamboos in transverse positions are placed across the bottom of the river. Figure 7 Example of drop structure from bamboo material in Indonesia (Source : PJT I) Beside the drop structure, another structure that can prevent river bed or river bank protection is a check dam. Check dams were built across the river to reduce the flow velocity and capture sediments carried by the flow, so that the flow depth and slope of the river bed can be reduced. These structures are usually made from locally available materials, such as wood, soil or stone. This structure has a high failure risk, but may provide temporary stabilization and can be combined with agronomic systems (using organic material). 7

14 The requirements of check dam location: Critical areas with % slope. Areas that have been attempted by land rehabilitation and soil conservation (Rehabilitasi Lahan dan Konservasi Tanah / RLKT) but the results are not yet effective. An area of around 30 ha of water catchment. The location is situated on a stable place. The process of construct check dam: Weaving or manufacturing of bronjong (bronjong is a structure made from piles of stone in a cage placed across the stream, twigs, bamboos and other local materials). Installation of bronjong (cage, wire, twigs, bamboos etc). Placing the stone into the bronjong wire cage. Binding of bronjong (wire, twigs, bamboos etc.). Strengthening the river bank. The maintenance of the check dam The maintenance includes repair of bronjong wire, woven twigs, bamboo / wood sticks which broken or damaged and recharging stones into bronjong wire and the strengthening of the river bank beside the check dam. It also needs a sediment removal when the sedimentation has occurred in the upstream part. Figure 8 Examples of check dam in Indonesia (Source : PJT I) 3. A capacity building module with educational and advocacy materials on promoting healthy river and eco-efficient water infrastructure development including the organization of training workshop on the development of the educational and advocacy materials. The developing of a capacity building module is on going, completed with education and advocacy material and promoting healthy live and eco-efficient water infrastructure development. The module will be used for the training program for the local community in the project area. 4. A training program for the stakeholders, majority for the local community, involved in the project with purpose to gain sustainability after implementation of the project. 8

15 The training is expected to be held in the end of June 2010, but may be delayed after the completion of the structural construction process, if it is considered necessary to show the result of structural construction. B. Project Implementation Implementing structural and non-structural measures: 1. Implementation of non structural measures, leading to preventing further catchment degradation (soil conservation) based on local community participation (e.g. bio-pores, land terracing, gully plug, regreening and/or reforestation) a. Bio-pores Justification : Bio-pores are appropriate technology and environmental friendly to dealing with flooding and reduce inundation problem with increasing the water absorption, converting organic trash to compost, utilizing the soil organism and roots and overcome the problem cause by inundation problems such as dengue and malaria. This method was chosen because it is easy and cheap, so in the future the local people can implement by themselves. The recommended amount of bio-pores holes. Number of holes that need to be made can be calculated using the equation : Total bio-pores holes = rainfall intensity (mm/hour) x impervious area (m 2 ) per hole (liters/hour) For example, for an area with rainfall intensity 50 mm/hour (heavy rain), the infiltration rate of 3 liters of water per hole per minute (180 liters/hour) on 100 m 2 of impermeable area need to be made = (50 x 100) / 180 = 28 holes. When the hole was made with a depth of 10 cm diameter 100 cm, each hole can hold 7.8 liters of organic waste for 2 3 days. Thus 28 new holes can be filled with organic waste generated during days. In this time interval, the first hole which already filled are decomposed into compost so that the volume has shrunk. And then the holes can be refilled with new organic waste and so on.

16 Existing Condition : - The poor condition of drainage system in Bendosari Village especially surrounding residential cause inundation problems during rainy season. - The making process of bio-pores holes are : 1) Making the holes with approximately 100 cm depth using bio-pores hole maker as shown in the pictures below. 2) When the hole is completed, the hole is filled with organic material. A PVC pipe of 10 cm high is placed in the upper part and filled/covered with sand. 3) To make sure that the bio-pores holes function properly, a test conducted by pouring water to the bio-pores hole. If the holes can absorb the water, this is meant that the bio-pores hole functions properly. Otherwise it needs to repeat the process properly. - The location of bio-pores holes was spread around 3 (three) Dusun.

52 6. Addendum Proposal Activities, to implement construction or installation of at least one eco-efficient modular/insitu structure to reduce pollution flow into the stream and to improve water quality Biogas Plant and Water Treatment To overcome the waste problem from the husbandry, need construction or installation at least one eco-efficient modular/insitu structure to reduce pollution flow into the stream and to improve water quality. The proposed structure is biogas plant equipped with waste water treatment. Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Biogas originates from biogenic material and is a type of bio-fuel. One type of biogas is produced by anaerobic digestion or fermentation of biodegradable materials such as biomass, manure, sewage, municipal waste, green waste, plant material and energy crops. This type of biogas comprises primarily methane and carbon dioxide. The other principal type of biogas is wood gas which is created by gasification of wood or other biomass. This type of biogas is primarily nitrogen, hydrogen, and carbon monoxide, with trace amounts of methane. 46

53 The gases methane, hydrogen and carbon monoxide can be combusted or oxidized with oxygen. Air contains 21% oxygen. This energy release allows biogas to be used as a fuel. Biogas can be used as a low-cost fuel in any country for any heating purpose, such as cooking. It can also be used in modern waste management facilities where it can be used to run any type of heat engine, to generate either mechanical or electrical power. Biogas can be compressed, much like natural gas, and used to power motor vehicles and in the UK for example is estimated to have the potential to replace around 17% of vehicle fuel. Biogas is a renewable fuel, so it qualifies for renewable energy subsidies in some parts of the world (source: In Indonesia, the common type of biogas plant is fixed dome, it is a dome type that can not be moved and cemented. This type of biogas plant had a various size, 4, 6, 8, 10 and 12 m 3 and categorized to earn subsidies from Indonesia Domestic Biogas Program (IDBP/BIRU(biogas rumah)). Type Note : Processing Capacity* (m 3 ) Gas Production per day (m 3 ) Required Cattle Waste per day** (kg) Required Water per day (liter) Required Number of Cattle * = Processing capacity meant the volume of biogas plant and the dome for the gas storage ** = Average storage time : 50 days The biogas plant size and dimensions have been decided based on the storage period of 50 days and 60% of gas storage. The fresh raw material (waste) being loaded into the plant/reactor and inside the reactor must be at least 50 days prior to release. The processing capacity must be able to accommodate 60% of gas produced within 24 hours. 47

54 Figure 39 The typical of Biogas Plant in Indonesia There are six main parts of a digester: inlet (mixing room) as a place of animal waste inside, the reactor (anaerobic digestive space), the gas reservoir (storage space), the outlet (the space separator), the gas transporter systems and animal waste compost pit that has lost its gas / slurry. Sewage and water mixture (mixed in the inlet or mixing room) flows through channels pipe into the digester. Mixing to produce gas through the digestive process reactor and gas generated is then stored in a reservoir of gas (upper dome). The animals waste that have lost the gas / slurry flows out of the reactor into the tank outlet (the space separator) and flows out into the compost through the valve hole in the tank overflow outlet. Then the gas flowed into the kitchen through a pipeline. The Biogas Development Model in Indonesia are generally composed of sections as follows, which is also shown in the sketch drawing in the previous Figure 39: 1. Inlet (mixing tank) 2. Inlet pipe to separate animal waste and sewage 3. Reactor 4. Gas container (dome) 5. Manhole 6. Outlet (separator space) and the opening burst 7. Main gas pipeline and a small tower 8.
