Abstract

Kebutuhan energi di berbagai negara lebih banyak dipenuhi dari bahan bakar fosil dan mengalami peningkatan setiap tahunnya sementara cadangan minyak bumi hanya cukup untuk 18 tahun ke depan. Berbagai penelitian telah dilakukan untuk memanfaatkan mikroalga sebagai bahan baku biodiesel. Scenedesmus sp. memiliki tingkat pertumbuhan dan produksi lipid yang tinggi dan memiliki asam lemak yang memadai untuk sintesis biodiesel serta dapat memanfaatkan bahan organik sebagai nutrisi berupa limbah cair tahu sehingga sinergi antara pengolahan limbah cair dan produksi biomassa dapat berjalan dengan baik.. Pada penelitian ini akan diteliti potensi mikroalga Scenedesmus sp. dengan variasi pemberian limbah cair tahu dalam medium kultivasi (0%, 20%, 40%, 60%, 80%, 100%) dengan perbandingan fotoperiod terang:gelap (16:8, 14:10, 12:12, dan 24:0) dan waktu pengambilan data pada hari ke-0, 1, 3, 5, 7, 9, 11, dan 13. Berdasarkan hasil penelitian diperoleh kadar lipid tertinggi sebesar 27,12% pada pemberian limbah cair tahu 20% dan fotoperiod 12:12 dengan efisiensi penyisihan COD sebesar 73,91%.

Abstract

Goal 6 of the SDGs has a target for clean water and sanitation, by 2030 the UN has a target of providing universal access to sanitation. Safely managed sanitation can support the progress to supporting socioeconomic development and promoting equality. In developing countries, a majority of the general population does not have access to proper sanitation. Therefore, there are still many challenges faced for sanitation in developing country. Unmanaged sanitation has a negative impact to human health and the environment. In developing countries that has a lot of under developed and rural area, community-based sanitation program is one of the approach for educating and improving sanitation. This study has an objective to evaluate the current implementation of community-based sanitation programs in Indonesia. This study is a literature review that analyzed various sources in a systematical way to evaluate the implementation of community based sanitation programs in Indonesia. In conclusion, the implementation of community based sanitation programs yield a positive impact for the targeted community. The factors that has influence are community involvement, funding and enforcement of sanctions.

Abstract

Ujungberung market is one of traditional market in Bandung city having high business transaction and generates a significant solid waste to be managed properly. In order to establish a proper solid waste management, the reliable data on waste generation is crucially required. The paper aims to find the waste generation through performing waste sampling procedure based on Indonesian Standard for 8 days consecutively. There were total 566 stalls available in the market and 85 stalls were selected as respondents for sampling and questionnaire. The results showed that the highest and lowest average of waste quantity were generated by food stall (3.16 kg/day) and tuber stall (0.02 kg/day), respectively. Based on units that may affect the waste quantity, the average daily waste generations are follows: 0,464 kg/stall, 0,109 kg/m2 area of stall, 0,240 kg/employee, 0,047 kg/hour of stall operational. Although the waste composition generated from each stall may vary, the most dominant type of waste predicted to be generated in the market totally were plastic, organic, and paper, respectively. According to the field observation and the questionnaire, most of seller dispose of their waste using plastic bag to the nearest waste storage. The data of waste generation resulted from the study could be used to predict the generation for other traditional market for establishing a better planning of the waste management system.

Abstract

The behavior of people who depend on the Citarum River Watershed (DAS Citarum) in disposing of waste has a direct impact on the damage and pollution experienced by the Citarum River. Therefore, the Citarum Harum program by the government is expected to change the Citarum River Watershed (DAS Citarum) community more importantly in terms of waste management. The purpose of this study is to determine the factors that influence the behavioral intention of the Citarum watershed community to realize the Citarum Harum. This research was conducted by surveying through questionnaires to 170 respondents. After collecting data, the data then processed using Partial Least Square (PLS) method with SmartPLS 3.0 software. The results of this study indicate that the Perceived Behavioral Control (PBC), Incentive Measure (IM), and Personal Norm (PN) factors significantly influence the Behavioral Intention (BI) respectively amount 16.3%, 15.9%, and 19.1%. While the Knowledge Theory (ETK) and Environmental Practices Knowledge factors influence the Attitude Towards Behavior (ATT) to understand in actualize citarum harum program respectively amount 38.4% and 21.7%.

Abstract

Water resources in Manggarai Regency are mostly supplied from springs. One of the villages in Manggarai Regency that uses springs is Bangka Kenda Village. Bangka Kenda Village requires drinking water of 10.41 Liters/second. This need for water is the result of drinking water projections in Manggarai Regency in 2037. Pressure values obtained from the results of manual calculations range from 5.63 meters to 93.82 meters. While the simulation results using the EPANET program, the pressure value is at 5.69 meters up to 93.84. The value of the manual calculation pressure with EPANET is not much different so that the pipe diameter selection is appropriate according to plan. The selected pipe is HDPE. The selected pipe diameter is 1.5 "; 2 "; 3 "; 4 and 5 ", respectively. The pipe has a water pressure resistance of 12.5 bar.

Abstract

Tofu industry waste pollution is still a serious problem. The high burden of tofu industrial waste pollutants is still a major problem. besides, the unavailability of the budget for processing and the limitations of a cheap and efficient treatment system are factors supporting the pollution of tofu waste in the environment. This study examines the efficiency of reducing BOD5 and COD treated with constructed wetlands using water jasmine plants (Enchinodorus palaefolius). The system used is the wetland subsurface with continuous flow. The media used include sand and biochar with a residence time of 12 hours 18 hours. Whereas pH, temperature, and flow rate are conditioned as control variables. The greatest efficiency of BOD5 and COD occurs in reactors using biochar media and a residence time of 18 hours with an efficiency of BOD5 of 50.52% and COD of 55.02%.
