Abstract

The Somber Small Industry Center's Regional Technical Implementation Unit (UPTD) is one of Balikpapan's tofu and tempeh industrial sectors. Based on observations performed throughout the implementation of tofu production at Mr. Rahim's production house, it is known that the production capacity of tofu varies every month due to the shortage of a tofu production plan, resulting in Mr. Rahim's production house losing 816 kg worth Rp. 20.400.000 in 2022. The purpose of this study was to plan and offer recommendations for tofu manufacturing capacity and time that are suitable for Mr. Rahim's production house. Forecasting moving averages, weight moving averages, exponential smoothing, and linear trend line models are applied in the tofu production planning approach. The research results in capacity planning and production time of tofu using the forecasting method of moving average over 3 periods and 6 periods, respectively, 6081 kg/month and 6025 kg/month; weight moving average over 3 periods and 2 periods, respectively, 5792 kg/month and 5504 kg/month; exponential smoothing method with alpha 0.80, 0.90, and 0.95, respectively, 5258 kg/month, 5080 kg/month, and 4990 kg/month; and the linear trend line model method of 6317 kg/month. The conclusion of this study using the best feasible forecasting method is the weight moving average with two weighting periods, with a total required capacity of tofu production time of 1671.0144 hours/year and a total capacity of available tofu production time of 1874.6112 hours/year due to the difference in actual demand with a forecast of 732 kg, which does not exceed the value of lost sales in 2022.

Abstract

Panti asuhan Yaumiddin merupakan lembaga sosial yang mendidik dan memelihara yatim piatu dan anak yang kurang beruntung di Kota Balikpapan. Keberlangsungan kegiatan di panti asuhan erat hubungannya dengan ketersediaan air bersih. Saat ini ketersediaan air bersih di panti asuhan masih kurang baik dikarenakan secara visual air yang digunakan terlihat keruh. Dengan fokus pada ketersediaan air bersih yang berkualitas, pengabdian ini mengidentifikasi, melakukan pemasangan, dan pemeliharaan infrastruktur pipa serta sistem filtrasi air yang sesuai dengan kebutuhan panti asuhan. Perbaikan dan infrastruktur aliran air yang dilakukan mampu meningkatkan debit air yang mengalir menjadi 0,3 liter/detik. Hasil pembuatan filtrasi air berhasil meningkatkan kualitas air yang tersedia dengan adanya perbaikan nilai pH yang mendekati netral (7), penurunan nilai pada uji kekeruhan dari 0,994 menjadi 0,126 NTU serta penurunan padatan yang terlarut (uji TSS) dari 178 menjadi 29 ppm.  Kegiatan terakhir adalah melakukan sosialisasi kepada masyarakat mengenai prosedur pemeliharaan sistem filtrasi air. Implementasi infrastruktur pipa dan sistem filtrasi air secara efektif meningkatkan akses terhadap air bersih, meningkatkan kesehatan dan kesejahteraan penghuni panti asuhan, serta mengurangi risiko terpapar penyakit akibat konsumsi air yang tercemar.

Abstract

The growth of electric vehicles is accompanied by an increase in the number of batteries and battery waste produced, which can ultimately have harmful effects on the environment. As a solution, battery pack remanufacturing has emerged as an effective alternative. However, challenges in the remanufacturing process include determining which battery pack components can be repaired and which require replacement with new components, ensuring that remanufacturing costs remain low while preventing potential future failures. This study aims to develop a remanufacturing decision model that integrates Failure Mode and Effect Analysis (FMEA) with a remanufacturing cost model. The study’s results outline the relationship between failure modes and battery pack components, whereby each failure mode can be classified to determine appropriate repair or replacement actions. While specific actions have been formulated, remanufacturing costs remain the final determinant in the overall battery remanufacturing decision. Based on the analysis, repairs or replacement of new part on 13 components associated with failure modes still render the battery pack suitable for remanufacturing, with a potential cost saving of more than 40% compared to purchasing a new battery pack.

Abstract

The Small-Scale Industrial Zone of Somber (SIKS) serves as a center for tofu and tempeh production, where one of the producers processes approximately 100 kg of soybeans into tempeh daily. The tempeh production process in SIKS contributes significantly to environmental impacts, particularly during the soybean boiling stage, which uses firewood as the primary energy source. The use of firewood generates higher emissions of greenhouse gases such as CH₄, CO₂, and N₂O compared to other types of fuel. This study aims to analyze the environmental impacts of the tempeh production process in SIKS using the Life Cycle Assessment (LCA) method supported by SimaPro software. The analysis results indicate that the boiling stage contributes the highest impact, with a score of 51.5 Pt, mainly due to the use of firewood. As an improvement strategy, a simulation was conducted by replacing firewood with liquefied petroleum gas (LPG), which showed a significant reduction in environmental impact to 4.44 Pt. This strategy also reflects the principle of sustainability by promoting the use of cleaner and more efficient energy sources to reduce the environmental burden. Therefore, the use of LPG is considered effective in reducing environmental impacts in the categories of human health, ecosystem, and resources in the tempeh production process at SIKS.

Abstract

Dissolved oxygen (DO) is a critical parameter in common carp (Cyprinus carpio) aquaculture, as low DO levels can cause stress, inhibit growth, and lead to fish mortality. Conventional measurement methods, such as manual titration or DO meters, are limited because they cannot provide continuous or real-time monitoring. Therefore, this study aims to develop an Internet of Things (IoT)-based dissolved oxygen monitoring system using the Waterfall development method to maintain optimal water quality in carp ponds. The system utilizes an ESP32 microcontroller, a DO sensor, and the Blynk platform as a real-time remote monitoring interface. It continuously measures DO levels, displays data locally on an LCD, and sends automatic notifications when the DO value falls below 5 mg/L. Field testing was conducted for one week at the Rama Graha carp pond, showing that the system achieved an accuracy of 92.7%, an error rate of 7.3%, and a precision of 98%. The developed system effectively supports farmers in maintaining stable water quality and reducing fish mortality. This study contributes to the development of practical, low-cost IoT technology for sustainable freshwater aquaculture management.

Abstract

PT XYZ, a company specializing in heavy equipment component remanufacture, is committed to ensuring that its processes run quickly and efficiently. However, from 2022 to 2023, the disassembly engine process exceeded the average processing time. Observations revealed that 24% of the time was categorized as waste setup time, necessitating a more objective reduction. This research aims to determine the actual total setup time, internal and external activities, and time reduction using the SMED and Fuzzy FMEA methods. The disassembly process includes the main disassembly, sub disassembly 1, and sub disassembly 2. Single Minute Exchange of Dies (SMED) is employed to identify and reduce setup time by distinguishing between internal and external activities. Additionally, this research integrates the SMED method with Fuzzy Failure Mode and Effect Analysis (FMEA) to identify potential risks in setup activities and determine which internal activities can be modified. Changes to external activities will be analyzed using the 5-Why's method to identify root causes and find solutions. Observations revealed that the average disassembly engine setup time was 20 hours and 12 minutes, consisting of 25 internal activities and 56 external activities. The SMED method resulted in an 18% reduction in setup time, and when combined with the Fuzzy FMEA method, the reduction reached 59%, equivalent to 8 hours and 17 minutes.
