Informasi mengenai fluktuasi hujan sangat penting terutama bagi masyarakat lokal yang masih bergantung pada sumberdaya alam. Tujuan penelitian ini adalah untuk menganalisis pola hujan di bagian hulu Daerah Aliran Sungai (DAS) Bengawan Solo. Informasi ini dapat digunakan sebagai dasar dalam perencanaan pemanfaatan sumberdaya air. Data curah hujan tahun 1990-2016 dari 14 stasiun penakar hujan dianalisis secara deskriptif untuk mengetahui fluktuasi hujan dan pergeseran musim. Curah hujan tahunan di hulu DAS Bengawan Solo bervariasi antara 1.433,5 mm hingga 3.231,2 mm dengan rerata mencapai 2.224,6 mm. Tidak terjadi perubahan awal musim hujan maupun musim kemarau, namun demikian durasi musim hujan mengalami peningkatan dari 7 bulan (Oktober-April) pada periode 1990-1998 dan 1999-2007, bertambah menjadi 8 bulan (Oktober-Mei) pada periode 2008-2016. Sebesar 90% curah hujan terkonsentrasi pada musim hujan. Pemanenan air hujan dapat dilakukan untuk mengurangi runoff di musim hujan sekaligus sebagai upaya penyediaan sumberdaya air di musim kemarau.

Landforms experience dynamics during the geomorphological process. The fluvial process occurs due to the flow of water from erosion, erosion transportation, and sedimentation activities. Sedimentation material is resulted from erosion transported through the river. Later the deposited erosion will produce landform variations. Therefore, information of landform dynamic is important in controlling runoff and floods. The purpose of this study was to identify and determine the dynamics of the fluvial landform in Grindulu River, Arjosari-Pacitan Segment. The method used is combination of desk analysis and field surveys. The desk analysis is conducted to identify the types of landforms through visual interpretation of SPOT-7 Imagery, while field surveys are to determine sample units using purposive sampling. Based on landform analysis in the Arjosari-Pacitan Segment, there were five fluvial landforms processes due to sedimentation namely point bar, channel bar, flood plain, meandering, and natural levee. The dynamics that occur are dominated by the aggradation process, namely the addition of flood plain landform area of 0.872 ha (0.216%), channel bar of 0.091 ha (0.019%), and natural levee of 0.014 ha (0.002%). The identification of landforms can be used as a basis in spatial planning to optimize water system in watershed.

Germadan is one form of lake management policy implemented through the establishment of institutions involving many stakeholders. The institutional management of the Rawa Pening Lake is a collective action to the preservation of the Rawa Pening Lake. This study aimed to evaluate the implementation of Germadan in the perspective of the theory of collective action. The research used a qualitative approach. Data collection through in-depth interviews, observation, and literature study. The descriptive analysis was carried out to describe the implementation and to identify the successes and failures of Germadan. Based the analysis, it can be concluded that as a collective action, Germadan has failed. This failure is due to imperfection of participation in planning and implementation of the program, and the lack of enforcement of agreed rules and lack of incentives for both economic and social incentives in their implementation.

Water erosion is one of the causes of degraded land and a decrease in land productivity. Improvement of degraded land needs to detect sources of erosion and vulnerability level of the degraded land. The research was conducted to predict the vulnerability of soil erosion and distribution of degraded land in order to support the implementation programme of Land Rehabilitation and Soil Conservation. The research was conducted in upper Solo Watershed. Soil erosion was predicted using Universal Soil Loss Equation (USLE). The analysis of Land Capability Class was undertaken to determine the suitability of current landuse with its capability. Analysis of critical land was based on the regulations of the Directorate General of Watershed Management and Social Forestry (BPDAS-PS) Nomor 4/V-SET/2013. The data used were DEM (Digital Elevation Model) Aster (30 m x 30 m), map of the Regional Physical Planning Program for Transmigration (RePPProT) scale 1: 250,000, map of forest area (1: 50,000) from BPKH (Forest Zone Determination Center), land cover map from BPKH (1: 50,000), Google Earth imagery, rainfall data from 93 rain stations and field surveys. The results show that the upper Solo Watershed is dominated by land categorized as potentially degraded (54%), followed by slightly degraded (35%), while land which is classified as degraded occupied 7% of the total watershed. The dominant land capability is categorized as V th class and limited by soil erosion (89%). Dry land agriculture areas were found at land capability VI th and VII th which should not utilized for agricultural activities. Implementation of agroforestry and teracing are alternatives to prevent further land degradation and to improve the current condition.
水土流失是土地退化和土地生产力下降的原因之一。改善退化土地需要查明侵蚀的来源和退化土地的脆弱程度。该研究旨在预测土壤侵蚀的脆弱性和退化土地的分布，以支持土地恢复和土壤保持方案的实施。该研究是在Solo流域上游进行的。利用通用土壤流失方程(USLE)对土壤侵蚀进行了预测。进行土地能力等级分析，以确定当前土地利用的适宜性及其能力。关键土地的分析基于流域管理和社会林业总局(BPDAS-PS) Nomor 4/V-SET/2013的规定。使用的数据是DEM(数字高程模型)Aster (30 m x 30 m)、区域自然规划程序(RePPProT) 1:25万比例尺地图、BPKH(森林区域确定中心)的森林面积地图(1:5万)、BPKH的土地覆盖地图(1:5万)、谷歌地球图像、93个雨站的降雨数据和实地调查。结果表明:上索罗流域以潜在退化土地为主(54%)，其次为轻度退化土地(35%)，退化土地占流域总面积的7%;占主导地位的土地利用能力为V类，受土壤侵蚀的限制(89%)。旱地农业区的土地容量为第6和第7，不应用于农业活动。实施农林业和梯田是防止土地进一步退化和改善目前状况的备选办法。

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.
印度尼西亚主要城市的人口增长对清洁水消费量的增加产生了影响。对清洁水的最大需求是满足家庭需要。家庭用水不符合效率原则。因此，为了满足水的需求，有必要使用其他来源，其中之一就是灰水。本研究的目的是通过添加木屑作为生物过滤材料来确定多媒体接触处理灰水的效果。本研究采用定量与定性相结合的方法，以木屑为生物过滤器材料进行实验。该研究于2018年10月在南Tangerang市的Villa Bintang Mas住宅进行。结果表明，添加木屑的生物滤料能有效去除污水中的污染物。生物过滤器对污染物浓度的降低效率从40.6% (BOD参数)到100%(大肠菌群参数)不等。然而，大肠菌群参数仍不符合标准质量，因此，需要额外的消毒剂来降低大肠菌群水平。

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.

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.","PeriodicalId":187244,"journal":{"name":"Jurnal Penelitian Pengelolaan Daerah Aliran Sungai","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116036323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.
