Abstract

Lake water contaminated with domestic sewage is a serious problem as it can pollute the surrounding environment, as in Telaga Rambit, Gresik. Turbid water quality indicates pollution, so a treatment process is needed before use. This study aims to analyse the effect of activator type and flow rate on the filtration process using the slow sand filter (SSF) method, with a combination of coconut shell charcoal and rice husk charcoal media. The flow rate variations used were 0.1 m³/h and 0.3 m³/h, with hydrochloric acid (HCl) and phosphoric acid (H₃PO₄) activators. The results showed that Reactor B, using H₃PO₄ at a flow rate of 0.1 m³/h, was the most effective variation in reducing pollutant levels, namely BOD by 1.9 mg/l, COD by 6.26 mg/l and TSS by 12 mg/l at the 25th sampling time. The H₃PO₄ activator has been shown to increase the adsorption capacity of activated carbon media, particularly in the capture of suspended solids. The low flow rate also provided better stability during the filtration process, allowing for more effective particle retention. After 25 minutes, the filtration media had not reached saturation point, indicating that filtration could be improved with longer contact times.

Abstract

Waste treatment is the main challenge in the tofu industry, especially for household-scale producers. As a solution, constructed wetland is an affordable, efficient, and easy-to-operate waste treatment method. The tofu industrial wastewater used in this study came from one of the home industries in the park, Sidoarjo. In this study, a variety of planting media and plant types were used. The planting media used are silica sand and gravel; biochar and mixed soil; as well as a combination of silica sand, soil biochar mixture, and gravel. And the plants used in this study are Cyperus Papyrus and Cyperus Rotundus. The purpose of this study is to determine the influence of planting media and the type of plants that will be used in the CW system. All planting media used showed the ability to reduce TSS, COD, and BOD parameters. Although there is a decrease in parameters only with the media, the average efficiency of parameter reduction with plant use has a greater value with a difference of 20% to 25%. For the comparison of the two types of plants, it can be seen that the yield of Cyperus Rotundus is larger, there is a difference in efficiency ranging from 2.5% to 3% with Cyperus Papyrus plant.

Abstract

Telaga Rambit in Gresik Regency, a water source for the local community, is currently polluted by domestic sewage. The coagulation-flocculation process is used to solve this problem. Chemical coagulants are often used in the coagulation-flocculation process, but chemical coagulants often produce sediment that is difficult to handle. Therefore, tamarind and papaya seeds were selected as natural coagulants due to their protein content which can act as polyelectrolytes. The aim of this research is to analyse the effect of pH and coagulant dosage in the coagulation-flocculation process and to compare the effectiveness of tamarind seeds and papaya seeds as biocoagulants in reducing BOD, COD and TSS. From the results of jar test analysis, papaya seed with a dose variation of 4000 mg/L and pH 7 is the best variation as it is able to reduce BOD up to 22.5%, COD 27.4% and TSS 51.22%. While tamarind seed at 2000 mg/L and pH 7 reduced BOD by 18.75%, COD by 23.4% and TSS by 46.3%. The results show that the two biocoagulants did not meet the quality standards in reducing BOD, COD and TSS in the lake water, so another combination process or use of other treatment alternatives is required.

Abstract

The increasing problem of water pollution due to high levels of heavy metals which are often found in well water in various regions affects water quality which can have a negative impact on public health and the environment. Therefore, an effective solution is needed to reduce this contamination. One promising solution is the use of activated carbon derived from organic materials, such as sugarcane bagasse and kepok banana peel. This research aims to analyze the optimal dose and effectiveness of activated carbon produced from sugar cane bagasse and kepok banana peel which is activated with 5% H₃PO₄ in the adsorption process to reduce iron (Fe) and manganese (Mn) levels in well water. The research was carried out with varying doses of activated carbon of 4 grams, 6 grams, and 8 grams, as well as varying contact times of 20, 30, 40, 50, and 60 minutes. The results of the research show that activated carbon from sugar cane bagasse and kepok banana peel has a significant ability to remove these two heavy metals with varying effectiveness. The results of this research provide a sustainable and environmentally friendly alternative for water treatment and open up opportunities for utilizing organic waste as raw materials in water treatment methods that can improve the quality of contaminated well water.

Abstract

This study examines how PT YM can improve the effectiveness of its inventory management by implementing the Just In Time (JIT) method. The main objective of the study is to overcome the problem of overstocking, which often occurs as a result of poor inventory management. Companies that use JIT produce items only in response to demand, which reduces inventory costs and storage requirements. According to the research, the implementation of JIT can increase production efficiency by 35% in an average of 11 days, with efficiency levels ranging from 27% to 38%. Moving average, linear trend and double exponential smoothing are some of the forecasting techniques used. Safety stock and kanban analysis are also used to ensure the best possible availability of raw materials. It is believed that the resulting recommendations will help with inventory management issues and serve as a guide for future inventory control studies.

Abstract

KPSP Setia Kawan has two types of farms, namely conventional dairy farms and organic dairy farms. The research results show that in the milk production process of 1 kg of ECM (Energy Corrected Milk) which was delivered to the farm gate for 1 year, the total carbon footprint of milk produced by dairy farms in 2010 was 1.23 ± 0.04 kg CO2 Eq/kg ECM, 80% comes from on-farm activities. This research will apply the Life Cycle Assessment method with the CMLIA Baseline impact method. This method can be used to carry out impact assessments in the livestock sector so it is common for LCA studies in the dairy sector so it is most suitable for conducting comparative studies. It is hoped that with this research, animal husbandry can find out the effectiveness of implementing organic cattle farming in reducing environmental impacts compared to conventional cattle farming and help promote animal husbandry that prioritizes environmental aspects in the production and supporting processes.

Abstract

Ketapang seeds (Terminalia catappa) are a potential source of vegetable oil as a feedstock for biodiesel production. However, the use of ketapang seed oil remains very limited. Degumming is a crucial step in biodiesel production as it determines the quality of the raw material preparation. Various methods can be used to remove gum, including heating and the addition of acids (H3PO4, H2SO4 and HCl) or bases (NaOH). The aim of this study is to maximise the quality of biodiesel feedstock by improving the degumming efficiency using different concentrations of phosphoric acid (H3PO4) and NaOH. The phosphoric acid concentrations used were 0.5%, 1% and 1.5% v/v and the NaOH concentrations were 0.5%, 1% and 1.5% w/w. The degumming process was carried out at 80 °C with stirring for 30 min at each stage. After degumming, ketapang oil has excellent clarity compared to before treatment. Based on the research conducted, the optimum degumming conditions were found at a phosphoric acid concentration of 0.5% v/v and a NaOH mass of 1% w/w, resulting in an FFA content of 0.4% and a density of 902.5 kg/m³.

Abstract

Motorcycles have become an important means of personal transport for the general public. In daily use, engine performance is crucial to meet everyday mobility needs. Modern automatic motorcycles use a CVT (Continuously Variable Transmission) system, which is a key factor in engine performance within the transmission system. This study aims to observe differences in engine performance through variations in roller weight using a dynamometer and Pertamax Turbo fuel. The sample roll weight variations are the standard roll weight of a Vario 150cc motorcycle which is 15.6 grams, a racing roll weight of 14 grams and a 16 gram roll weight. The specific use of Pertamax Turbo fuel is to achieve maximum engine performance due to the perfect combustion that Pertamax Turbo can create with an RON of 98. This results in maximum power, acceleration and top speed.

Abstract

The Pertamina Research & Technology Centre Facility is a laboratory building designed to support research activities, where laboratory space is a critical element in the design of a research and laboratory centre. Due to activities involving chemicals, crude oil and other products, the risk of chemical and biological contamination, radiation exposure, explosions and fires is higher than in most other facilities. This potential hazard requires a well-designed building access system to prevent the risk of fire and explosion. The aim of this study is to evaluate whether the building access for fire and explosion protection in this facility is adequate and meets established standards. The evaluation method used is a qualitative approach through a literature review on the principles of fire access in buildings, which is then applied to the Pertamina Research & Technology Center facility located at Jl. Daan Mogot Km. 16, West Jakarta. The results of the evaluation indicate that the fire egress in this facility meets the established standards, allowing the occupants to conduct research activities more safely against potential fire and explosion hazards in the future.
