Abstract

Land is an important resource in a watershed because of its position as a processor. The condition of a watershed depends on the land management and its compliance with its performance. The purpose of the research is to evaluate the performance of Rawakawuk Sub Watershed from the land aspects. Guidelines of Watershed Evaluation and Monitoring, i.e. the Regulation of Director General of Land Rehabilitation and Social Forestry or PerDirjen 04/V-Set/2009 was used to analyze parameters of Vegetation Cover Index (VCI), Land Use Suitability Index (LUSI), and Erosion Index (EI). The results showed that the study area  has 53% of pine and teak monoculture, and 20,7 % of agroforestry private forest, therefore the VCI is 73,2%. The LUSI is 93,7% which implies that 93,7% of the area is suitable to its land capability. In addition, 36,1% of the area is exposed to very severe erosion. Since the solum depth is relatively deep (>90 cm), the tolerable soil erosion is high and EI tends to be small. Around 60,3% of the area has an average EI of 71,1 which is classified as moderate. Based on the cumulative value of VCI, LUSI and EI, Rawakawuk Sub Watershed can be classified as slightly good. However, conservation practices should be applied to the very severe erosion areas.

Abstract

Gully erosion is the most siginificant forms of land degradation. Gully distribution can indicate land degradation. Density level of gully shows the level of land degradation on a catchment. This research aims to identify the distribution of gully and to calculate density level of gully erosion in Kaliwungu Watershed. Distribution of gully and density level of gully was analyze based on land use map and landform map. In addition, analyze the characteristics of slopes, vegetation, infiltration, and land cultivation to determine the factors affecting gully erosion.The researchers was applying field survey to collect gully erosion data. Gully distribution was overlayed on land use map and landform map. Land use was delineated by interpretated aerial photograph of Kaliwungu Watershed. Aerial imagery with the support from the result of Sentinel image processing was used to observe vegetation density. Landform and slope were deliniated from Terra-SAR X DEM. Gully catchment was delineated by interpretated Terra-SAR X DEM and aerial photograph of Kaliwungu Watershed.  Analysis to determine the factors that influenced gully was done descriptively. The analysis was conducted based on the result of overlay of gully distribution on land use map and landform map. The result of this research were map of gully distribution and map of density level of gully erosion in Kaliwungu Watershed with a scale of 1: 10.000. Gully erosion formed on erosin zone to deposition zone, but there were 3 gully that formed on residual zone. There were three density classes of gully in Kaliwungu Watershed which are high, medium, and low. The process of intensive gully takes place only at the some point with intensive land cultivation or land that has been highly disturbed by human activities such as settlements. The study result shows that land use and land cultivation was the factor that influenced the formation of gully erosion.

Abstract

Tradition and religion interact closely to the rural community, which is shown in their culture. This concept was applied to spring conservation in the rural area. The objective of this research was to show the role of tradition and religion in the use of spring based conservation by rural community. This research used a case study method. Data were collected by field surveys and interviews. The respondents were chosen randomly because the characteristic of the community was homogenous. The results of this research showed that tradition and religion in form of cultural ritual called spring cleaning (nguras sumber) and “be grateful to God” (slametan) had been capable to keep the sustainability of water resources in the spring, both the quantities and qualities of water. Nguras Sumber and Slametan were directed by a traditional leader called “Juru Kunci” followed by the community. The water resources were used for domestic water consumption, tourism, agriculture, and livestock throughout the year, even excessive in the rainy season. Therefore, the culture of Nguras Sumber and Slametan could be maintained as a form of spring’s conservation.

Abstract

The causes of floods can vary, but they are rarely caused by only one factor. The purpose of this research is to find the cause of flood that hit Garut City on 20 September 2016. The method used is flood water supply analysis and flooded area analysis which is developed by WMTC Solo. The results showed that the water supply in the Upper Cimanuk watershed was very high due to high rainfall the day before (110 to 255 mm /day), high antecedent soil moisture (35 to 44 mm), very vurnerable (52%) land condition on Upper Cimanuk watershed due to land use that was not in accordance with its ability and forest area which only 17.9% of the watershed area. Based on the analysis of flooded areas, which was flat area around the river were identified as prone areas to flood such as Garut, South Tarogong and Cilawu. The flood potential in the Upper Cimanuk watershed can be reduced by changing the land use pattern on the very sloping land from vegetable farming to agroforestry, reforestation, and applying soil conservation practices. For flooded areas the reduction of flooding can be conducted by increasing the drainage channel, building infiltration wells and dykes along the river and managing the riparian.

Abstract

Declining productivity of plantation forest due to low soil fertility. This condition has forced  managers to make efforts in manipulating the tree growing environment. One such effort is by introducing cover crops species from legumes (LCC), to control surface runoff, soil erosion and input nutrient into the soil. The research aims to determine the effectiveness of LCC in controlling total runoff and sedimentation in Eucalyptus pellita plantations, through dynamic model simulation. The dynamic model of STELLA version 9.0.2 was used to study water and nutrient cycles, focused on the application of LCC to reduce total runoff and sedimentation. The results showed that LCC could drop the total runoff of average 35% in the 1 - 2 years old. In the 1styear it decreased from 1,530 mm to 994 mm, while in the 2ndyear it decreased from 1,240 mm to 806 mm. The declining also occurred in the sediment content, in the 1st year it decreased from 12.20 tonnes/ha to 7.93 tonnes/ha, and the 2nd year it decreased from 6.63 tonnes/ha to 4.36 tonnes/ha. These research findings can be used by the environmental manager  to minimize potential land degradation, especially during the post-harvest until the young plantations (0-2 years old) phases.

Abstract

Landslide is a hydrometeorologycal disaster that usually happens in Indonesia. The purpose of this study was to determine the level of landslide vulnerability in Banjarnegara District. This study employed survey and descriptive quantitative methods by using a formula of landslide vulnerability, with variables: natural and management factors. The analysis used in this study was overlaying the predetermined formula and weighting it. The results indicated a variety of vulnerability classes, which were: 1) non-vulnerable zone of 44.88 ha (0.04%), 2) slightly vulnerable zone of 7,800.84 ha (7.29%), 3) fairly vulnerable zone of 88,505.80 ha (82.74%), 4) vulnerable zone of 10,423.32 ha (9.74%), and 5) very vulnerable zone of 196.16 ha (0.18%). The dominant parameters for landslides in Bajarnegara were: rain, geology and regolith. Mitigation techniques employed in those areas should be based on community-self-supporting mitigation through the development of disaster resilient villages. Disaster resilient village is a village that is responsive and can minimize disaster risks through adaptation. Several measures can be done independently autonomously by the community including increase the alertness during rainy period, seal all cracked soil due to the fault movement, and protect the soils through slope (stabilization and protection of slopes).

Abstract

Population growth has an impact on increasing the need for land to fulfill peoples food, thus it may decrease in its carrying capacity. Therefore a study has been conducted to evaluate the carrying capacity of the land to meet the needs of the local community at Forest Area for Specific Purpose (KHDTK) Gombong, Kebumen District, Central Java. Secondary data collection was covering population, land area, productivity and price from agriculture, plantation, forestry, livestock and fishery, rice prices at producer level. Another secondary data collection was collected from Central Bureau of Statistics Kebumen, Forest district Service, District and villages. Data were analyzed using a descriptive quantitative method by calculating the supply and demand of land to know carrying capacity of the land. The result of this research showed that the availability land in KHDTK Gombong was 68,559.72 ha while the required land was 101,909.56 ha, thus experiencing a deficit of -33,349.84 ha. The deficit condition in KHDTK Gombong can be fulfilled from Kebumen regency that has a surplus or cooperate with other regions. This condition makes the attention of Local Government to overcome KHDTK Gombong such as increase land availability, land conversion towards other more profitable business, land intensification with new technology and land conservation.

Abstract

Increasing degradation of a watershed ecosystem is a problem that needs to be resolved. Therefore, a study was conducted in order to determine the socio-economic and biophysical vulnerability of Solo watershed in relation to watershed management. This research was conducted in Solo Watershed. The collected data include primary and secondary data. The potential and vulnerability of socio-economic and biophysical were evaluated using the  Formulation of Watershed level Characterization System. The results of the study showed that (1) the socio-economic of the whole Solo watershed classify as moderate category, with the highest vulnerable district was Wonogiri due to high population density and high land vulnerability, (2) land vulnerability for the whole Solo watershed is in the medium category, with the most vulnerable land category was in Madiun and upstream Solo sub-watersheds, (3) the most prominent flood vulnerability was in the downstream of Solo sub-watershed, (4) the typology of watershed management was classified as highly vulnerable because the territorial typology was in the very high vulnerable and the watershed typology was medium vulnerable. By knowing its vulnerability level, the rehabilitation program can be directed to areas with a high level of vulnerability.

Abstract

Drought identification is needed as a baseline for its mitigation. Several drought identification methods are available, but they need to be tested in dry climates. The purpose of this study was to identify dry area and its mitigation in Moyo Watershed, West Nusa Tenggara Province. Paimin and Syarif methods were used in the study. The results showed that the Paimin method produced a uniform vulnerability map, which was "medium vulnerable" for the entire watershed. This is because the applied parameters only have one class for the entire watershed. The Syarif method provides more variable results because the parameters produce several classes of vulnerabilities. However, the later method has a weakness in applying the depth of groundwater.  Moyo watershed only had one class, whereas the depth of the groundwater level varied from 4 to 11 m in the dry season. The two methods produced the same results and there were classified as “medium susceptible” for Moyo watershed. For dry areas, it is necessary to reclassify the drought class of each parameter. By combining the two methods above, it is expected to obtain more accurate results. To get the Water Use Index parameter efficiently, the number of population and water usage should be more efficient. Extentions to the community about the effectively water usage is important. Adaptation to drought can also be done by making reservoirs and setting cropping patterns.
