Abstract

Industrial waste in Depok still a problem raised because its contents were not following the government’s quality standards. Contaminants were considered pollutant are Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Suspended Solids (TSS) were quite high. One of these wastes was tofu wastewater which produced a foul odor and pollutes the environment when discharged directly into water bodies. Lack of industrial owners' education of the economic value of the waste caused direct disposal without being utilized first. Therefore, this Community Service activity aims to determine the feasibility of tofu industrial wastewater as a Spirulina sp. culture medium and provided education to the tofu factory owners, to utilize their liquid waste. In the implementation several stages are carried out, namely literature studies, sampling, implementing wastewater assessments, counseling also training. The result of this activity is tofu industrial wastewater can be utilized as a medium for cultivating Spirulina sp. which added economic value while reducing the environmental pollution. This can be seen from the results of Spirulina cultivation on the 10th day where the Optical Density (OD) continues to increase and harvested for further use.

Abstract

Daerah penelitian dilakukan di TPST Bantar Gebang dan sekitarnya yang merupakan perbatasan 3 desa yaitu Desa Bantar Gebang, Desa Sumur Batu, dan Desa Ciketing Udik Kecamatan Bantar Gebang, Kabupaten Bekasi, Provinsi Jawa Barat. Dalam Penelitian ini menggunakan data primer berupa data resistivity dengan menggunakan metode geolistrik konfigurasi wenner-schlumberger, yang kemudian difokuskan untuk menganalisis  nilai resistivity guna untuk mengetahui rembesan dan akumulasi limbah yang terdapat pada daerah penelitian. Dari pengolahan  data resistivity menggunakan metode geolistrik didapat bahwa nilai resistivity terhadap limbah sampah pada daerah penelitian memiliki nilai resistivity berkisar antara 4 hingga 40 Ωm. Akumulasi limbah bawah permukaan berada pada jarak jangkauan 300 meter dari TPST Bantar Gebang dengan kedalaman 2 meter hingga 23 meter dan dengan  arah rembesan dari arah barat laut - tenggara dan tenggara – barat laut.

Abstract

Infiltration rate and rainfall are one of the parameters in determining water catchment areas. In an area that has a high level of rainfall, it is very good to be a water catchment area. Water catchment areas must be maintained and protected so that they can be used to incrase groundwater reserves and prevent flooding, so a spatial plan is needed in determining water catchment areas. This study aims to determine the rate of infiltration in the ara of Mount Pancar, Bogor, West Java. Infiltration rate data was collected directly in the field using a double ring infiltrometer and rainfall data was obtained from BMKG data at Citeko Station. The final result of these data will be made a map of the infiltration rate and rainfall map. The results of the study in the study area obtained an infiltration rate of 0,096 m/day – 0,553 m/day with rainfaal of more than 3000 mm/year. From these data, it can be concluded that the rate og infiltration and rainfall are closely related to each other in determining water catchment areas.

Abstract

Disasters are events that can endanger life and disrupt people's lives. It can be caused by natural and non-natural factors, as well as those caused intentionally by humans, resulting in fatalities, property losses, natural and environmental damage, and psychological effects on disaster victims. Natural disasters themselves are a threat to the community and the Regent. The Rumpin District, Bogor Regency, as the capital of the candidate for the newly autonomous region of West Bogor Regency, has triggered population growth and the development of the area has become very fast. Deliberation of the potential and resources owned and assessed to be a strategic area because it borders the City of South Tangerang, Banten. Therefore, the activities of managing natural resources and the environment as well as regional development must pay attention to the preservation of their functions and capabilities so that development activities do not become a trigger for disasters, and the location of the development must be in an area that is safe from disasters. This study was conducted to find out how the geological conditions are related and the factors that affect the potential for landslides, and to make a map of the land movement susceptibility zone in the research area. This research uses Geographic Information System (GIS) and the parameter assessment method, where the parameters needed are geological parameters, soil type, rainfall, land use, and slope. The disaster risk zoning is expected to be a source of knowledge for the community and the city government of Bogor for disaster mitigation and increase awareness related to land movement vulnerability zones.
