Abstract

Yogyakarta, Indonesia, has various municipal wastewater treatment (IPAL) facilities; however, only 40% are operational. The study examines how IPAL affects groundwater quality and identifies its causes. Ngaglik, one of three province districts with the largest IPAL number and population density, is the research site. This study only measures microbiological groundwater quality based on Total coliforms and Eschericia coli, according to APHA 2017. Inverse distance weighing (IDW) maps microbiological groundwater quality. The results of the study showed that the observed area had Total Coliform values of 0–170 MPN/100 ml and Escherichia coli concentrations of 0–7. Eleven of the twelve test samples met Permenkes drinking water quality requirements No. 492/Menkes/Per/IV/2010 and PerGub DIY No. 20 of 2008. Seven E. coli concentration measurements exceeded drinkable water requirements. This study showed that E. coli bacteria may have infiltrated groundwater near the sample site. The incident was the first sign that Kapanewon Ngaglik Municipal IPAL was malfunctioning. This data should help assess and improve the effectiveness of the municipal IPAL at the study site and other local IPALs.

Abstract

A Travelling Salesman often encounters a problem where they have to find the shortest route that can be passed when they want to visit several places without having to go to the same place more than once. So, it is necessary to find the shortest route that is useful for efficient distribution. The Travelling Salesman Problem is solved using the branch and bound method with three different approaches: Breadth First Search, Depth First Search, and Best First Search. These three approaches will be compared regarding their effectiveness and efficiency. The case study used is a team of cigarette product sellers in the Kuningan area who will distribute their products to four villages. The route currently in use is from Warehouse → Karangmangu Village → Jalaksana Village → Peusing Village → Sidamulya Village → Warehouse with a distance of 19,8 km. The result of this study obtained the shortest route with the path from Warehouse → Karangmangu Village → Sidamulya Village → Peusing Village → Jalaksana Village → Warehouse with a distance of 19,7 km. And the comparison result obtained is that The Breadth First Search approach requires more calculations with 28 calculations, while The Depth First Search approach requires 25 calculations, and The Best First Search approach requires 23 calculations.

Abstract

Overcapacity experienced by the Payakumbuh Regional Final Processing Site (TPA) caused landslides in 2017 so several rice fields and agricultural land around were buried. This TPA serves waste for four Regencies/Cities with a volume capacity of 400,000 m³. Every day there are approximately 200 tons of waste coming in from Payakumbuh, Limapuluh Kota, Bukittinggi, and Agam. Now the TPA's storage capacity is only around 130,540 m³. With landslides and almost full landfills, this proves that waste management at the TPA is not optimal. The aim of this study was to examine the waste management strategy at the Regional TPA of Payakumbuh using a qualitative approach using the SWOT Analysis (Strengths, Weakness, Opportunities and Threats) method. The research begins with measuring the composition of waste, interviewing the role of scavengers, and identifying internal-external factors in the SWOT analysis. Measurement results for the composition of organic waste are 81.24% and 18.76% inorganic waste, potential for recycled waste is 69.05% in the form of compost and 2.40% for saleable. The results showed that landfill facilities functioned well except for sorting sites, while the role of scavengers was very useful in reducing inorganic waste by 3 tons/day. And results of SWOT analysis are in quadrant I with 3 strategies produced, including increasing composting facilities at TPA, implementing policies for TPA users and increasing empowerment of scavengers at TPA.

Abstract

The ability of an industrial company to produce a product will certainly depend on the ability of the machine used as a tool to produce every part of the product. Over time, increased market demand must be accompanied by an increase in production rates. Where this requires industrial companies to have high productivity, especially in the machining parts used in the production process. We can measure this effectiveness using the Overall Equipment Effectiveness (OEE) method, which is often used to measure the productivity of the machine or equipment used. Based on the research results, it can be seen that the average value of Overall Equipment Effectivities (OEE) on a stamping machine is 39.9%.

Abstract

Raw material procurement policies play an important role in the production activities of a company. In order to maintain customer trust, PT. XYZ is very concerned about the quality and timeliness of the products it produces. This research was conducted to analyze raw material procurement policies and apply the Economic Order Quantity (EOQ) method which is considered effective as a measure to optimize inventory control efforts and minimize total inventory costs. This study shows that the total inventory cost (TIC) using EOQ has a more economical amount of Rp. 150,080, compared to the TIC resulting from company policy, namely Rp. 967,671. The EOQ model also takes into account the economical purchasing process which is carried out 5 times a year with a purchase quantity of 239 units per order, reorders are made when the remaining stock is 44 units and safety stock is 32 units. In order to maximize the inventory function, the maximum stock or limit on the availability of stock in the warehouse is also taken into account, which is 277 units.

Abstract

Abstract Residual construction material is defined as something that is more than what was planned, both from the results of the work and the remaining, damaged, or lost material so that it can no longer be used according to its intended purpose. From the results of observations that have been made in several subsidized housing locations in Langsa City, there are many leftover materials from architectural work, because of that it is necessary to do an analysis of the type of waste material, the causes of waste and waste prevention measures that are often carried out. The method in this study uses descriptive statistical methods using Kendall's W so that rankings are obtained for variables, types of waste material, factors that cause waste, and waste prevention actions that are often carried out. The results of this study, the type of material that has the largest quantity is sand with a total score of 97, cement with a total score of 93, and red brick with a total score of 45. The dominant factor causing the amount of remaining architectural work material in subsidized housing is external factors with a total score of 116, material management with a total score of 83, and workers with a total score of 80. Then the form of preventive action that can minimize the waste of material that is often done is checking periodically (monitoring) with a total score of 125, purchasing materials as needed with a total score of 125, and increased coordination between workers with a total score of 124.

Abstract

The construction of subsidized housing in Langsa City has increased, yet it fails to bridge the gap between housing demand and supply, especially in metropolitan areas. To ensure the development of subsidized housing benefits the community, careful attention is required. This study aimed to identify the most suitable area for subsidized housing and its requirements in Langsa City. Using the Analytical Hierarchy Process (AHP), the study assessed five criteria: accessibility, facilities and infrastructure, environmental conditions, buildings, and subsidized house prices. The AHP findings achieved a consistent index of 7%, meeting the required threshold. Results revealed that accessibility holds the highest weight (0.33), followed by facilities and infrastructure (0.20), environmental conditions (0.19), building conditions (0.17), and house prices (0.11). This highlights accessibility as a significant factor in purchasing subsidized housing in Langsa City. Langsa Barat District emerged as the best-fitted location for subsidized housing, with a weight value of 4.09. Despite increased construction efforts, addressing the housing demand and supply gap remains a challenging task in Langsa City's metropolitan areas.

Abstract

The current achievement range for renewable energy is around 12%, making it the greatest hurdle. Investment in biomass renewable energy has positive environmental and social impacts despite its lucrative financial potential. However, there are a number of dangers associated with this investment. Therefore, investment might be successful in the development of sustainable and sustainable biomass energy if a thorough investigation and careful planning are carried out. Biomass energy has a lot of potential, but it has yet to reach its full potential because of challenges like high production costs, inconsistent biomass availability, and a lack of supporting infrastructure. Policy and regulatory support, research and innovation, management of the biomass supply chain, increased production scale, diversified biomass sources, increased awareness and education, public-private partnerships, increased efficiency, consolidation of support finance, and environmental impact management are all crucial steps toward a solution. Improvements in conversion technology, sustainable management of biomass resources, increased government assistance, and investments in supporting infrastructure are all necessary steps toward making Indonesia's biomass energy more competitive on the global stage.
