Social Capital in Improving Community Welfare through Village-Owned Enterprises in Belun Village
Get PDFVillage-owned enterprises (BUMDes) are institutions or organizations that carry out activities or businesses to develop the economy in villages. The main objectives are to increase Village Own Source Revenue (PAdesa), contribute to improving community welfare, alleviate poverty, and reduce unemployment. However, according to Belun Village APBdes data, BUMDes "Karya Mandiri" has not provided PAdes, and administrator and member engagement has been declining annually. Social capital is the capacity of the community to take collective action to achieve common goals through an institution The purpose of this research is to measure the level of social capital in the Belun village community in improving welfare through BUMDes. This research uses Venn diagrams and Social Network Analysis (SNA) to map and measure relationships and information among individuals, groups, or institutions. The results show that the level of community participation in Belun village is at a moderate level, with high-density levels and centrality. There are 17 central figures connected to the BUMDes in Belun village. Independent BUMDes have not yet made financial contributions. Based on the conclusions and recommendations, it is suggested that social capital in independent BUMDes needs to be strengthened, especially in conveying information to the community about the activities carried out, to foster a sense of ownership in the efforts developed by BUMDes and to enhance the capacity of BUMDes management through mentoring from relevant agencies and village governments
Erosion Rate Analysis and Land Conservation Direction Based on Geographic Information System in Way Rarem Subwatershed, Lampung Province
Get PDFThe Ministry of Forestry has designated the Way Rarem sub-watershed, part of Tulang Bawang, a critical watershed, as a priority. Several reasons cause land criticality, including deforestation and inappropriate land use, which cause erosion and sedimentation. In this case, the criticality of the watershed occurs due to the high erosion rate, which impacts flooding in the Way Rarem subwatershed area. Over the past year, there have been flood disasters at five points in the Tulang Bawang watershed. Based on information from BNPB (National Disaster Management Agency), the flood disaster affected 140 families. The losses that occur due to flooding that arise due to erosion and sedimentation need to be studied in more depth; therefore, the situation in the Way Rarem Sub-watershed is important to study further. The objectives of this study are to determine the Erosion Hazard Index, measure the erosion rate in the Way Rarem sub-watershed using the USLE method, and provide adequate conservation strategies. The required data are rainfall data, soil type, slope, and land use in 2019 and 2023 as a comparison. GIS was used to process all the data. The results showed that the erosion rate in 2019 was 21933.9 tons/ha/year, whereas in 2023, it was 14187.4 tons/ha/year, with the Erosion Hazard Index dominated by the \u27Very High\u27 category. For conservation direction, three alternative conservation activities are carried out, namely by vegetative, mechanical, and vegetative-mechanical methods. Based on the results of the analysis, the appropriate conservation direction to reduce the erosion rate is vegetative-mechanical conservation, which can reduce the erosion rate by 66.9% of the existing erosion rate. From the results obtained, it is hoped that new concepts in land conservation that have not yet been implemented in the Way Rarem Sub-watershed can be taken into consideration. Combining two conservation methods, vegetative and mechanical, can be an alternative to controlling erosion that occurs in the Way Rarem Sub-watershed

Get PDFMount Semeru eruption in December 2021 caused fatalities, injuries, as well as housing and economic losses for the people of Sumberwuluh Village, Lumajang, East Java, Indonesia. As one of the areas through which the Mount Semeru river basin passes, cold lava floods are an annual disaster in Sumberwuluh when the rainy season comes. This research was done through direct field observations and interviews, supported by secondary data sources in the form of literature, to examine the Sumberwuluh community\u27s resiliency in disasters, emphasizing the economic and social aspects. The research findings suggest that the Sumberwuluh people successfully adapted to economic changes and developed social cooperation to survive. Economic resilience involves changing livelihoods to become sand and stone miners, as well as efforts to find alternative sources of income. On the other hand, social resilience includes coordination and cooperation between residents and forming groups as a preventive measure against disasters. This resiliency is built through the community\u27s collective efforts to overcome the economic crisis and face the disaster threat
Optimization of Slab Bottom Grouting: A Case Study Utilizing an Underplate Grouting Model with Brinkman Equation and Level Set Method
Get PDFThis paper presents a case study on a slab bottom grouting project, focusing on the development and optimization of an underplate grouting model. The primary research objective is to determine the optimal grouting implementation strategy for the project by analyzing the impact of various structural parameters, grout properties, and grouting process properties on the grouting radius. The model incorporates the Brinkman equation and the level set method to explore the impact of various structural parameters, grout properties, and grouting process properties on the grouting radius. Through extensive analysis, the paper identifies the optimal implementation strategy for the project. The study reveals that parameters such as subbase permeability (K2), grouting pressure (P), and grouting time (t) positively affect the grouting radius, while the grout viscosity (μg) has a negative impact. The influence of grout density (ρg) and displaced fluid density (ρa, ρw) on the grouting radius is found to be negligible. Based on the underplate grouting model, the paper determines the optimal grouting implementation scheme for the slab bottom grouting project, specifying a grouting pressure of 1.2 MPa and a grouting time of 60 seconds. Furthermore, the effectiveness of the proposed implementation strategy is indirectly validated through the Falling Weight Deflectometer (FWD) analysis. The results demonstrate that the underplate grouting model successfully eliminates voids at the bottom of the slab, providing conclusive evidence for the reliability of the grouting strategy proposed by the model. Overall, this study contributes to the understanding and optimization of slab bottom grouting projects, offering valuable insights for practitioners in the field

So that overall social capital can support program implementation effectively and on target in supporting post-COVID-19 village recovery
Changes in Land Use of Protected Rice Land to Support Food Independence using Remote Sensing Technology
Get PDFThe agricultural sector plays an important role in efforts to deal with food availability. National food independence is one of the programs that is the government\u27s focus. Especially amid the threat of a world food crisis. President Joko Widodo emphasized the need for cooperation to build food independence by developing food according to the characteristics of each region. East Java Province, one of the potential areas, has agricultural land covering an area of 2.29 million Ha. It was recorded that in 2019 it converted 9,597 Ha of agricultural land which was used for warehousing, industry, and property areas. This is because the industrial, residential, and other service sectors are seen as more profitable than agriculture. This paper aims to identify rice fields, plan food crop areas for Protected Rice Fields, and determine the food needs of the population in Malang Regency. Knowing this can be a basis for developing agricultural land policies in Malang Regency. The method used is descriptive quantitative and High-Resolution Satellite Imagery remote sensing techniques in 2022. Existingly, some are in non-rice field land use and are divided into 10 classifications. The results show that in 2022 the rice fields within the protected rice fields area will only be 28,089.24 ha, and outside the protected rice fields area of 1,391.11 ha, capable of producing 335,455.62 tons of rice, it is predicted that this will meet the population\u27s need for rice until 2031. Food crop area plan The spatial plans within the protected rice fields covering an area of 33,436.32 hectares is capable of producing 381,798.62 tons of rice, with this amount of rice production predicted to still be able to meet the population\u27s needs until 2047, when the population\u27s rice needs will be 380,649.69 tons.6.044,82 ha. So recommendations are needed to improve data on raw rice fields and land protection strategies

Land Use Response in Volume of Infiltrated Analysis to Control Fire Risk in the Liang Anggang Tropical Peatland Forest in South Kalimantan
Get PDFLiang Anggang Protected Forest is an area formed from peatland. Peatlands have a role in conserving water resources, reducing floods, preventing seepage of seawater, and so on. Damage to the water system in peatlands is often caused by individual activities that are not well controlled. This is thought to have resulted in the depletion of water in the peat soil, making the soil dry and flammable in the dry season. This research aims to analyze the rate of infiltrated water in the Liang Anggang Block 1 Protected Forest area. It was also found that the volume of infiltrated water in the natural conditions of the protected forest, assuming that there is no current use of the protected forest area, is 9,097,126.998 m3/year, and the total after there is current utilization of 8,498,889.127 m3/year. Due to the current utilization carried out in the area under review, the infiltration volume value decreased by 6.576%. Based on this research, it is very necessary to maintain land use in the Liang Anggang protected forest to maintain the volume of infiltrated water in the area
