Abstract

Food industry wastewater has characteristics that contain high organic matter and suspended solids. Most of the methods used are physical and chemical treatment because these methods have high efficiency and effectivity. In designing a new wastewater treatment plant, the treatability assessment is essential to any consideration or reference in planning the treatment process to be implemented. This research aims to obtain treatability assessment results that will be used as consideration in planning treatment units in WWTP according to the characteristics of wastewater tested. The removal results of the sedimentation test with Imhoff Cone were able to remove 51.2% COD, 64.04% BOD, and 95.21% TSS with the optimum settling time of 40 minutes. The samples test continued to the rapid-slow mixing test using the jar test, resulting that by adding coagulant at the optimum dose of PAC 120 mg/L, it was capable to remove 68.21% of COD, 73.22% of BOD, and up to 98.07% of TSS at the end of the process. Based on the assessment results, the physical and chemical treatment can remove suspended solids pollutant parameters with high efficiency so it will be considered to be used in planning Wastewater Treatment Plants for this food industry.

Abstract

One source of raw water for drinking water is river water. The raw water source for drinking water must meet the requirements for quantity, continuity, and quality. Raw water for drinking water must meet class I water quality requirements. This study aims to assess of the potential for water availability and water quality in the Serang River. Analysis of water availability used statistical methods and simulated rainfall-runoff with the HEC-HMS model. Calibration of the hydrological model was carried out in sub-watersheds where there were observational discharge data. Water availability is reviewed in the second-order river. Water quality status was analyzed using the Pollutant Index and Storet methods. The results of the analysis of water availability for reliable discharge with a probability of 80%, 90%, and 95% in several sections of the Serang River to order 2 rivers can be presented in the form of a flow duration curve. The results of the analysis of the status of water quality in several sections of the upstream Serang river based on the Storet method and the Polluter Index method show that in general, it is in a slightly polluted condition.

Abstract

The Klampok River is one of the rivers that crosses the Bandungan, Bawen, Bergas and Pringapus Districts. The increase in the number of residents in the river basin which is not matched by the availability of land encourages the conversion of land functions that are not in accordance with their designation. The existence of the Klampok River as a water body receiving wastewater resulting from anthropogenic activities has caused the Klampok River to become polluted. Thus, it is important to study the water quality and water quality status of the Klampok River for nature conservation. This study aims to determine the water quality status of the Klampok River using the water quality index method, namely the National Sanitation Foundation – Water Quality Index (NSF-WQI) with reference to class II river water quality standards. NSF-WQI is a method that uses several specific parameters to determine river water quality.DO, fecal coliform, pH, BOD, nitrate, phosphate, temperature, turbidity, and total solids.The 2018 water quality index using the NSF-WQI method is in the range54.13 – 65.38with medium-good quality status. Meanwhile, the water quality index for 2019 using the NSF-WQI method is within the range35.47 – 66.60with moderate status, except for sampling point 6 which has bad status.

Abstract

Climate change as a global phenomenon is inevitable, including in Indonesia. Its impacts include rising sea levels, expanding coral bleaching, and declining coastal ecosystems, particularly mangrove forests and coral reefs.  Many research explores the characteristics of vulnerability to climate change in coastal cities and seeks feasible adaptation options for these cities with method used involved surveys of residents, interviews with experts, and statistical analysis and modeling. Although efforts have been made to prevent climate change, there is still a lack of research that explores the broader impacts of these efforts. In this regard, few studies have measured the social, economic, or environmental value that arises from these efforts. This study aims to evaluate, measure, and assess the impacts that have occurred as a result of the implementation of the program from environmental, economic, welfare, and social perspectives comprehensively. The result show that the SROI study results indicate that the Pulau Tahan program has positive economic, social, and environmental impacts. However, the on-field study also found a less positive fact regarding the availability of crab seedlings.

Abstract

Sarimukti Landfill operations use a controlled landfill system. The Cipanawuan River is affected by the operational impact of this Landfill. This study aims to identify the effect of leachate from the Sarimukti Landfill on the water quality of the Cipanawuan River. The research method calculates water quality status based on the Decree of the State Minister for the Environment No. 115 of 2003 concerning Guidelines for Determining Water Quality Status. River water quality standards are based on Appendix VI of Government Regulation No. 22 of 2021 concerning implementing Environmental Protection and Management. Water quality parameters identified are parameters that exceed quality standards. Based on the water quality status calculation shows a decrease in water quality from upstream to downstream of the river. The downstream part has been heavily polluted, indicating that there is influence from Sarimukti Landfill operations. Based on the research results, Sarimukti's Treatment Plant's flowing quality for TSS, BOD, and COD is needed to meet quality standards. This can affect water quality, and there is a relationship between the influence of Sarimukti Landfill operations on the water quality of the Cipanawuan River, which is near the Landfill.

Abstract

This study uses the pollutant index method to determine the form of river utilization by the surrounding community and the level of river water pollution. The research method used in this study is qualitative and quantitative analysis. Qualitative descriptive analysis method is used to analyze the form of river utilization by the community. Analysis of river water quality used quantitative method which refers to the Decree of the Minister of Environment 115/2003 concerning Determination of Water Quality Status using the Pollution Index (PI) method. The results of the analysis show that the community uses the Pepe River as a source of water and rainwater storage, waste disposal sites, fishing grounds, drainage channels, and agricultural irrigation. So that it has the potential to experience water pollution due to the entry of domestic-industrial waste. Based on PI, the flow of the Pepe River is proven to be lightly polluted, with the results of several parameter measurements showing results above the quality standard. Therefore, one of the recommendations that can be applied to overcome these problems is to develop the concept of Community-Based Development by involving the active role of all society levels in planning and implementing river management and development activities.

Abstract

Black Soldier Fly or Hermetia Illucens (BSF) is known for its potential as a biological agent that helps in the process of natural conversion of organic waste. Resulting compost and a large number of BSF colonies, potentially to be use as a non-food raw material in bioenergy production. The Method is BSF conversion experiment by direct transesterification reaction using Lab-scale bioreactor in 100ml three bottle neck flasks, the solution mixture consists of BSF powder, immobilized whole cell biocatalyst, and solvent. The Result is although in appearance the structure of the test mixture solution did not show an oily character, but based on the viscosity and density test, the test solution had density value 0.81 g/cm3 and viscosity value 1,024 mm2 /s which are above the value of the viscosity and density of methanol but still below the value of the viscosity and density of both SNI and EN14214 biodiesel standard, this could be due to insufficient separation or reaction, imperfect condition, and impurities that are still present in biodiesel products. It can be concluded that a transesterification reaction has occurred in this trial, however further analysis and more experiments are required to definitely conclude the changes in biodiesel production.

Abstract

Vegetation is an important component in an ecosystem. Padalarang Sub-District is a sub-district in West Bandung Regency with the smallest area but the most densely populated among other sub-districts in West Bandung, with a density of 3,478 people km2. The purpose of this research is to analyze the level of vegetation density using the Normalized Difference Vegetation Index (NDVI) technique as a consideration, especially for the government regarding development program arrangements. The method used was Landsat 8 image interpretation with NDVI, and the results will be classified according to the classification of vegetation density used. As a result, the density of vegetation has decreased from 2013 to 2021, area of non-vegetation and sparse vegetation land indicates, increasing by 5.3% and 4.51%, respectively. In the classification of fairly dense, dense, and very dense vegetation, density decreased by 4.39%, 4.86%, and 0.55%, respectively, which has resulted in reduced green areas becoming built-up areas along with the development of the number and mobility of the population. It is necessary to increase the amount of vegetation and stipulate development regulations that take into account the existence of vegetation as a support for ecological functions.
