Abstract

Population growth in major cities in Indonesia has implications to the increase of clean water consumption. The highest demand of clean water is in fulfilling household needs. The use of clean water for household needs does not follow the efficiency principle. So that in fulfilling the water needs, it is necessary to use other sources, one of which is grey water. This study aims to determine the effectiveness of multimedia contacts by adding wood shavings as biofilter material in treating grey water. The applied method in this research is quantitative with a qualitative descriptive approach, by conducting experiments using wood shavings as a material for biofilter. This research was carried out in the residential of Villa Bintang Mas, South Tangerang City in October 2018. The results showed that the usage of biofilter materials with the addition of wood shavings was effective in removing the pollutant of the grey water. It is indicated by the level of biofilter efficiency in reducing pollutant concentrations ranging from 40.6% (BOD parameters) to 100% (Coliform parameters). Nevertheless, Coliform parameters still do not meet the standard quality, therefore, there is a need for additional disinfectants to reduce Coliform levels.

Abstract

ABSTRACTFlash floods frequently occur in Indonesia. Flash flood can be caused by natural and human factors. This paper discusses the causes and mitigation of flash flood using a case study in Banyuwangi. On June 22th 2018, flash floods occurred in the residential areas of Garit, Karang Asem, and Bangunrejo Hamlets. Flash floods were triggered by heavy rainfall the day before, which reached 90 mm/day. The three hamlets are located in Alasmalang Village, Singojuruh Subdistrict, Banyuwangi District. The study began with a field survey, analysis of the damage, and the causes of a flash flood, and its alternative treatments. The suspected source of the material was the landslide material, approximately two million cubic meters from the Pendil Mountain. Some of the material were carried away by the river flooding caused flash floods in the three hamlets. The small width of the bridge was not able to be passed by trees and other flash flood material, so water overflowed the roads and houses. Based on the results of the study, it is recommended for disaster mitigation in the form of structural and non-structural actions. Structural measure in the form of bridge elevation and construction of sediment retaining weirs, while non-structural actions are in the form of an early warning system and dissemination of flash flood hazards.

Abstract

The regencies of Probolinggo, Lumajang, Jember, Bondowoso, Situbondo, and Banyuwangi are located in the Eastern part of East Java and called as Tapal Kuda. These regions are actually on fast development. The development to service human settlement generates land use change from natural into urban or developed areas. The change in land use will generate more runoff, erosion, and sedimentation from the watersheds. This study examined the effect of land use types and their percentage areas on erosion rates. The Universal Soil Loss Equation (USLE) was used to predict the erosion rate. The erosion rate of four land uses, which were forests, paddy fields, plantations and settlements, were calculated and compared. The values of the erosion rate were obtained by the statistical value per pixel in the watershed. Fifteen watersheds in the Tapal Kuda area were used as the samples. The results showed that the relationship (r2) between forests, rice fields, plantations, settlements and the erosion rate: 0.2; 0.2; 0.2 and 0.03, respectively.

Abstract

Population growth, urbanization, industrial development, and agricultural activities increase water demand on the watershed. An increase in water demand will propagate the excessive exploitation of surface water and groundwater resources. This will probably influence the water balance of the watershed. Therefore, understanding the water balance is a necessity. Continuous imbalance between water supply and demand will generate many serious environmental problems. A study of agricultural water balance is needed to answer the question whether the available water resources can meet the needs of sufficient water for irrigation. The study was conducted in Rawatamtu sub-watershed which was part of Bedadung Watershed. The Water Evaluation and Planning (WEAP) model was used to analyze agricultural water balance. The procedure included inventory data, installing WEAP on the system, running the WEAP, and using WEAP for simulating future water balance conditions. The simulation results showed that agricultural water balance for the next 10 years will be more frequently in surplus condition rather than in deficit condition. The water surplus was estimated to occur in the year of 2020, 2021, 2023, 2025, 2027 and 2028. The highest surplus occurred in the year of 2028 which reached 56.59 million m3. Furthermore, the potential water balance deficit was projected to occur in 2019, 2022, 2024 and 2026.

Abstract

Grobogan Regency is one of the areas in Central Java that experiences drought almost every year. However, Ngaram-aram Hamlet in Crewek Village in the Grobogan Regency almost has not affected by drought in the dry season due to some springs located in this area. Increasing the community participation in water management could be obtained by strengthening the social capital. The objective of this study is to determine the social capital variables in the management of springs by identifying: 1) trust and community solidarity in spring?s management, 2) social Norms in spring?s management, and 3) social networks in spring?s management. The results of the research show that spring?s management was carried out both physically and spiritually. Trust and solidarity in spring?s management could be seen in regulating and distributing water to houses, and in contributing to the finance of spring?s management. The existing social norm is in the form of command sand prohibitions in spring?s management that contain social values, rewards and punishments. The social network in spring?s management at Ngaram-aram appears in a special set of relationships among groups of people who utilize the springs with characteristics of relationships that could be used to interpret social behavior motives from the people involved in them. This network has economic function to obtain water for household and agricultural purposes, social function in security and socialization, and communication flow of information. Indicators of the social network existence could be seen from 1) individual centrality 2) individual closeness, and 3) togetherness between individuals.

Abstract

Landslides are still a threat in some areas in Karanganyar Regency which has mountainous topography. Landslides cause in loss of property, and lives. Community participation in landslide mitigation is very important because the community is dealing directly with landslides. One of the roles of the community in landslide mitigation can be measured by the willingness to pay (WTP). The aims of this study are 1) to determine factors that influence WTP for reducing the impact of landslides, 2) to determine the value of WTP for landslides mitigation. The method used in this study is contingent valuation methods by calculating the amount of WTP to reduce the risk of landslides and the factors that affect WTP. This study used primary and secondary data. Primary data were obtained using open interview techniques with 100 respondents in some villages in Karanganyar District, who are at risk of landslides, while secondary data was taken from the Statistics Agency (BPS) and Regional Agency for Disaster Countermeasure (BPBD) of Karanganyar Regency. The results showed that incomes and poverty affected the WTP for landslide mitigation significantly. The average willingness to pay for landslide mitigation in the form of construction of cliff walls, closure of cracks and reparation of waterways in Karanganyar Regency is Rp. 26.307,00 per month.

Abstract

Infiltration rate in a watershed is very important for water management. There are many methods for estimating the rate of infiltration in a watershed. Among of them are direct measurements, hydrograph analysis and water balance calculation. The purpose of this study was to estimate infiltration in the sub watershed  under pine forest. The method was based on a relationship between water balance and regression of monthly rainfall and discharge. The results showed that the infiltration rate of pine forest in Watujali Sub Watershed  range from 125 mm/year up to 1,193 mm/year. The infiltration rate was highly depended on rainfall as the input. In  2010 with 5,826 mm rainfall, the infiltration rate reached 1,193 mm/year. Estimation of infiltration using water balance data was easy to implement because it only used data of streamflow, rainfall and evapotranspiration.

Abstract

Low level of sedimentation is a success indicator of watershed management. Measurement of sedimentation can be conducted directly or through erosion prediction approach. This research aimed to compare sediment yield from prediction by USLE erosion approach using three types formulations of rainfall erosivity with direct measurement. The field data were collected during 2015 in Lowereng Sub Watershed, Sempor District of Kebumen Regency. The slope steepness was derived from ASTER Global Digital Elevation Model and land cover was obtained from World View 2012. Three methods for estimating rainfall erosivity were Utomo and Mahmud, Bols, and Lenvain equations. The USLE applied for every land unit. By considering Sediment Delivery Ratio (SDR), the predicted soil erosion from USLE was converted into sediment yield. The direct measurement of sediment yield was conducted by taking suspended sediment in the outlet of sub watershed. This research indicates that the predicted sediment yield calculated using USLE approach was higher than the direct measurement. The predicted sediment yield using Lenvain’s equation was 3.49 ton/ha (196%), which was the closest to the direct measurement (1.18 ton/ha).

Abstract

Paradigm change of watershed management towards participative management brings consequences in the involvement of stakeholders in the decision-making process. While on one hand it can increase the social legitimacy of various watershed management policies and activities, the involvement of many stakeholders on the other hand may delay the achievement of consensus and reconciliation of interests. This study aims to examine the influence of social networks built among members of the Central Java Watershed Management Coordination Forum (Forum DAS) on the achievement of consensus with regards to a watershed planning. The research method used agent-based modeling simulation combined with in-depth interview data of forum members. The simulation model was developed using Netlogo 6.02 software. The simulation results show that the structure of the established communications network at this time has not been able to facilitate in the achievement of consensus, but tends to create formation of opinion polarization.
