Abstract

The aim of this research is to develop an efficient drying conveyor that uses heat from the incinerator at the Waste-to-Energy Power Plant (PLTSa). The process involves decomposing waste in the incinerator, which generates heat to drive the drying conveyor. This conveyor speeds up the drying of the waste, reduces the water content and improves the waste-to-energy efficiency. This study also discusses the main components of the conveyor, factors affecting the design, the cost of manufacturing the conveyor, and provides a practical solution for developing waste management technology that is technically and economically better. The results showed that the designed drying conveyor has a total weight of 163,716 kg and a manufacturing cost of Rp. 7,627,800. The use of this drying conveyor has also been shown to increase the reliability of the system by reducing the frequency of maintenance and the risk of damage. From a cost perspective, this solution is more effective in the long run because it reduces operating costs and additional fuel consumption. In conclusion, the use of drying conveyors with incinerator heat recovery is an innovative step that supports the energy efficiency, sustainability and operational effectiveness of the PLTSa.

Abstract

Waste management is a major challenge in Indonesia, with waste generation expected to reach 20.3 million tonnes per year by 2022. Karawang, West Java, is one of the areas with limited waste treatment capacity and infrastructure, with waste production reaching 900 tonnes per day and only 400 tonnes sent to landfill. This study aims to test the efficiency of waste drying using a conveyor dryer using heat from the incinerator. The research method used was an experimental trial with steps including collecting initial data, operating the dryer and analysing the drying results. Tests were carried out on several types of waste, namely vegetables (cabbage), fruit (oranges) and a mixture, to evaluate the reduction in water content and drying efficiency. The test results showed that the conveyor worked well at a temperature of 60°C and the components worked according to the settings. The drying efficiency varied between 16.67% and 56.90%, with an average water content reduction of 1.24 kg in 4 hours for cabbage vegetable waste. The drying process showed that the waste experienced a significant reduction in water content, depending on the type and weight of the waste.

Abstract

Automated access control systems have been widely used in recent years due to their high accuracy and security. In this study, we present an intelligent and secure electronic gate based on facial recognition and vehicle number plate recognition. The system combines multimodal biometric technology with face recognition using the 'face_recognition' package and automatic licence plate recognition (ALPR) using YOLOv8 and PaddleOCR to enhance the security of access to restricted areas. The system was able to correctly recognise 29 out of 30 faces, while all licence plates were accurately recognised, even at different times. The results show that the automated gate system has been successfully developed and tested with an accuracy rate of 96.67%. This success demonstrates the potential use of multimodal biometric technology to improve the security and efficiency of access control systems in various applications, such as office environments, residential areas and other public facilities. Further research can be directed towards improving the resilience of the system to different environmental conditions and expanding the database of recognised faces and vehicle number plates.

Abstract

The need for electricity in industry is very important, so a device called a boiler was created to produce electricity and water steam. Boilers are a profitable choice to achieve the goal of meeting the increasing energy demand while fuel reserves are getting scarcer by the day, as well as high safety requirements, especially in industry, so in this case, research was conducted on the use of electric power for palm oil mills at PT. Serdang Jaya Perdana in processing palm oil shells and fibres, which are then used as fuel in boiler stations. From the results of the research conducted on the total electricity consumption for the palm oil production process at PT. Serdang Jaya Perdana is 650 kW/day. The highest efficiency is found at the thresher station, where the efficiency of the use of electrical energy reaches 90%. Meanwhile, the lowest efficiency was at the clarification station, which reached 77%. An optimal increase in production capacity can increase the efficiency of electrical energy use. The estimated Rupiah to be spent to use palm husk as fuel is 1062 kg/hour = 25,500 kg/day, so for one month it reaches 765,000 kg/month, so it can be converted to Rp. 688,500,000/month.

Abstract

The large number of disturbances that occur at the feeders result in power outages, which have an impact on reducing the reliability of the electricity system. One of the faults that occurred in the PT. PLN (Persero) ULP Medan Timur is a broken cable/wire cross section on a medium voltage overhead line (SUTM) or a damaged component of a medium voltage overhead line (SUTM). As a result, the energy (kWh) produced by the generator cannot be distributed, resulting in significant losses for PLN and losses for consumers. Therefore, the step taken to prevent this failure is to carry out preventive maintenance on the feeder. From the results of preventive maintenance obtained in this research, it was found that SAIDI = 0.1057 hours/customer/year, SAIFI = 0.0528 times/customer/year, CAIDI = 2.001 hours/time CAIFI = 0. 4995 hrs/hour, ASAI = 0.9997, ASUI = 0.0002, while from the results of corrective maintenance it was found that SAIDI = 0.4414 hrs/customer/year, SAIFI = 0.2643 hrs/customer/year, CAIDI = 1.67 hrs/time. CAIFI = 0.5987 times/hour, ASAI = 0.9990, ASUI = 0.0009. Thus, comparing the results of the calculation of the overall reliability value on the GU.03 feeder after preventive maintenance in 2022 in PT. PLN (Persero) ULP Medan Timur work area SAIDI = 0.0211 hours/customer/year, SAIFI = 0.2643 times/customer/year, CAIDI = 0.7983 hours/time, CAIFI = 12.526 times/hour, ASAI = 0.99995, ASUI = 0.00004.

Abstract

Sukaraja Unit is a Water Treatment Plant (WTP) with a treatment capacity of 20 litres/second, Sukaraja WTP is operated by Perumda Tirta Sukapura Tasikmalaya Regency which was established in 1975 based on the legal basis of Regional Regulation of Tasikmalaya Regency Level II No. 7 of 1975 which is still in operation. The main concern is the water quality of the Ciwulan River and the produced water from the Sukaraja Water Treatment Plant (WTP). This assessment is based on design criteria from literature and applicable regulations, which are compared with water quality, water quantity, water continuity and WTP performance assessment based on existing data or secondary data. The raw water quality recorded several parameters that did not meet the quality standards and the dimensions of the treatment plant were not based on the design criteria. The basis of the existing problems is caused by the unsuitability of the operating system of the Sukaraja Water Treatment Plant. Water quality problems are caused by various activities in the area around the Ciwulan River, such as domestic waste disposal and the use of the river for agricultural irrigation. Improving the operating system of the Sukaraja Water Treatment Plant, repairing any damaged WWTP, and recommending unit dimensions that meet design criteria are suggestions that can be given from these problems.

Abstract

The brick industry sector has the capacity to generate pollution in the form of harmful dust particles that can adversely affect the environment and workers health. The research uses a quantitative approach with an analytical observational design, cross sectional study. In addition, researchers conducted an analysis of risk factors related to respondent obiter total dust particulate levels, inhaled dust levels, working duration, exposure duration, and the utilization of personal protective equipment. The measurement results showed the average total dust level was 1748.47 µg/Nm3 and the average respirable dust level of 75 respondents was 4.56 mg/m3. This increases the risk of respiratory symptoms such as coughing, coughing up phlegm, and shortness of breath. Variables associated with respiratory symptoms were inhaled dust levels (p=0.023), working period (p=0.040), exposure duration (p=0.032), and use of personal protective equipment (p=0.015). The multivariate test resulted in four significant variables: inhaled dust level (p=0.022), working period (p=0.039), exposure duration (p=0.029), and use of personal protective equipment (p=0.023). In conclusion, the combination of inhaled dust levels, longer work periods, exposure duration, and inadequate use of PPE increased respiratory symptoms in workers by 99.5%.

Abstract

Universal access to water, sanitation and hygiene (WASH) is a basic human right that reflects well-being. However, disparities in access to WASH persist in Indonesia, influenced by economic factors, education and sanitation behaviours. In urban areas, urban poverty exacerbates the gap in access to WASH, with the urban poor vulnerable to inadequate sanitation due to economic and knowledge constraints. In Kecamatan Bandung Wetan, which is located in the middle of Bandung city, this condition is still found, where low-income groups are vulnerable to the fulfilment of proper sanitation. The sanitation index is a tool to evaluate the sanitation system in a community. The sanitation index was analysed using exploratory factor analysis. The variables that make up the index are based on the 5 pillars of Community-Led Total Sanitation (CLTS). The results of the analysis show that the sanitation index in Kecamatan Bandung Wetan is built by the factors of clean water use, household welfare, low prevalence of environmental diseases, faecal user interface, and final disposal of household waste, with the highest sanitation index value found in Kelurahan Citarum.

Abstract

The fish processing industry often produces large amounts of waste. The abundance of these wastes can be used as liquid organic fertiliser so that it would not become pollution. This research will use cork fish head waste which had 17.72% C-organic; 0.189% nitrogen; 0.126% phosphorus; and 0.041 potassium with banana stalks as additional material which had 15.68% C-organic; 1.35% phosphorus; 2.13% potassium; 0.02 nitrogen to be used as liquid organic fertilizer. This research was carried out in 3 stages. The first was the preparation of the main ingredients, followed by the preparation of the bioactivator solution and then the fermentation process. The fermentation process was carried out in 5 different containers, each containing 10, 20, 30, 40 and 50 ml of bioactivator solution. Samples were taken on days 7, 10, 13, 16 and 19 to test for nutrient content. The results showed that the liquid organic fertiliser from cork fish head and banana stem with the best results and meeting the SNI standards was obtained in samples with 30 ml of EM4 added to it and fermented for 10 days, with a C/N ratio of 12.187% and total macro-nutrients (N + P2O8 + K2O) of 5.887%.

Abstract

Cement production has the potential to increase greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2) emissions. The cause of CO2 produced by the cement industry is reported to come from two sources, namely the combustion process in the kiln and the calcination process in the clinker making process. The large amount of CO2 gas produced in the production process puts pressure on every cement industry to try to find alternative fuels and raw materials to maintain or reduce CO2 emissions. One of the alternative raw materials that can be used as a source of fuel and alternative raw materials is hazardous and toxic waste with certain criteria. This study is an observational study, in which the cement production process and waste management in one of the cement industries are observed to obtain primary data in the form of the types of waste used. Internal waste is used as a substitute for raw materials and fuel substitutes. The process of waste utilisation in the cement industry is carried out by co-processing. The process of waste utilisation requires control, so each activity must be monitored. The results show that the cement products resulting from the process of using waste as a raw material substitute are of good quality and meet the criteria contained in the Annex to Ministerial Regulation No. 6 of 2021.
