STP UNIT SOBO BANYUWANGI
https://ejournal.unma.ac.id/index.php/j-ensitec/article/view/8748
<p><em>PT. Suri Tani Pemuka (STP) is a pond company in Banyuwangi that has various departments according to their tasks and functions, one of which is the mechanical and electrical (ME) department. In carrying out its tasks, the ME department heavily relies on the need for spare parts in repairing machine breakdowns in the workshop. However, there is a constraint faced, namely the delay of spare parts in repairing water turbine machine breakdowns due to lack of inventory control, especially for water turbine machine spare parts. Therefore, the Active Based Coasting (ABC) and Economic Order Quantity (EOQ) methods are used to solve this problem. The aim of this research is to determine the level of spare parts inventory based on cost, the level of spare parts inventory based on forecasting results, and to determine the ideal economic ordering calculation in spare parts inventory. The results of implementing ABC still show delays in spare parts inventory. After being improved using EOQ, the EOQ calculation results are as follows: Gear box gear 13 units, Gear box bearing 41 units, Turbine fan 6 units, Electric motor bearing 19 units, Seal cover 19 units, Oil seal 38 units, Turbine clutch 4 units. The implementation of the EOQ method in the inventory system or application shows that its use can reduce the expenditure of ordering goods more efficiently and effectively than relying solely on the ABC method.</em></p>Eritrian Bisma PrimayandaHerdiana DyahHarliwanti Prisilia

<p><em>In facing intense competition in the repair service industry, UD. MBS Audio needs to engage in continuous efforts to enhance service quality and understand the changing dynamics of customer needs. Therefore, the aim of this research is to identify and improve service quality, as well as to design an action plan to enhance services at UD. MBS Audio. This research utilizes the Importance Performance Analysis (IPA) method as a tool to translate customer expectations related to product or service quality. From the calculation results using the IPA method, Quadrant IV is identified as the top priority because it is considered highly important by customers and requires special attention as its performance has not yet reached optimal satisfaction levels. Critical attributes in Quadrant IV include P1, P5, and P10. A thorough evaluation of service quality, divided into four quadrants based on the IPA method, indicates that attributes in Quadrant IV (Top Priority) need continuous improvement to enhance their performance. The company's main focus should be on sustained improvement efforts to enhance the performance of these attributes, such as the cleanliness and tidiness of the facilities provided by UD. MBS Audio, providing satisfactory service results according to customer preferences, and offering guaranteed warranties.</em></p>Gian Dwi PrasetyoEndang SuprihatinMuhammad Yusuf

<p><em>CV Sinar Mas is a company in the Footwear manufacturing sector. Based on data, demand for footwears fluctuates, causing CV Sinar Mas difficulty in producing the number of raw materials for footwears ordered. The company also has not used an optimal raw material inventory control system. Therefore, the company experienced an excess of raw materials which occurred in November-December 2023, resulting in a buildup of raw materials which caused high production costs and decreased quality because it was too piled up in the warehouse. So, there must be planning and control of the availability of raw materials in order to obtain minimal costs and maintain the quality of raw materials. This research uses the Lot Sizing method, namely LFL (Lot For Lot) and POQ (Period Order Quantity). The goal is to determine the order quantity with minimal costs.</em></p>Fira FarhanaHandy Febri Satoto

<p><em>This analysis illustrates how changes in warehouse structure affect the smooth operation of a company or factory. At PT</em><em>. </em><em>Tjakrindo Mas, there is an irregular arrangement of finished product storage. causing a pile of goods that are not in accordance with the type so that during the retrieval process using a forklift there are difficulties due to the area that is not large so that it must be assisted with a hand pallet to carry the product to a wider area so that it can be reached by a forklift. That way it will waste a lot of time just because of the difficulty of wanting to transport goods. The method to be applied in the storage arrangement is the shared storage method, organised by placing finished products based on the FIFO (First In First Out) principle. This will minimise transport time as well as ensure efficient use of space.</em></p>Bella KharismaHandy Febri Satoto

<p><em>The duck farming business is an activity where farmers process ducks to breed and maintain them to obtain benefits and results from this activity. Ducks are quite popular among various groups, from small children to the elderly. UMKM in the Jombang area are located on Jl. Gatot Subroto No. 29A Mojongapit, Jombang. These UMKM are KUB chicken farms and broiler duck hatcheries. Hatching of broiler ducks is carried out using an automatic hatching machine that can turn the eggs automatically. The UMKM hatching machine processes 500 eggs each period. If the temperature and humidity method is not checked periodically, the egg hatching yield will be 75%. If you want to increase the hatching presentation, you can check regularly to reach 80%, but this takes too much time and energy. Therefore, I will make a tool that can regulate the humidity of the incubator. In solving this problem, the QFD method is used to fulfill consumer desires in making tools. Using the QFD method will make the tool making more optimal because before the tool is made a survey is carried out to determine consumer interest. The results of this research are tool designs that are made according to consumer interests.</em></p> <p><em> </em></p>Ilham Dwi SeptianHandy Febri Satoto

<p><em>Pak Temmy Rahadi's Tempe UMKM is one of the tempe making UMKM located in Ds. Karangandong, Kec. Kedamean, Gresik. This UMKM was founded in 2010. Mr. Temmy Rahadi's tempe UMKM has a daily tempeh production target of 450 to 600 pcs and uses 80 kg to 100 kg of soybeans for daily production. The majority of customers are market middlemen, penyetan sellers, and home-based people in Kedamean, Gresik. In developing tempe MSMEs, there are various aspects that need to be considered to improve product quality and market competitiveness. One critical aspect is the tempeh packaging process, which plays an important role in ensuring product safety and quality. Currently, Mr. Temmy's tempeh MSMEs are facing significant problems related to the plastic hole punching tool for tempeh packaging which uses a knife in the process before packaging. The tool for punching plastic packaging using a knife requires a long processing time and also the results of the punching are not uniform, resulting in imperfect holes in the plastic packaging, thus making the tempe fermentation process less than optimal. Therefore, researchers are interested in raising this problem. By making a plastic hole punch tool for tempeh packaging, we hope that it will be able to improve the performance of tempeh production. In designing a plastic hole punch tool for tempeh packaging, researchers used ergonomic anthropometric approaches.</em></p>Abdilah Fajar KhoirullohHandy Febri Satoto

<p>CV. XYZ is a distributor of building materials but focuses on PVC pipe products under the Target brand. CV. XYZ was founded in 2013. At CV. XYZ is very necessary for inventory scheduling which needs to be carried out by CV. XYZ in order to always meet consumer demand. The author suggests inventory calculations and scheduling to meet consumer demand using the Distribution Requirement Planning (DRP) method. In the DRP method there are several stages of data needed, namely demand data, inventory, lead time, holding cost data. Data processing in this DRP method is demand forecasting, determining Lead Time, determining lot size, calculating safety stock, and creating DRP tables. In the calculation results, results were obtained for distribution costs for 5 pipe products which initially had excess stock and could not meet demand. For Target Pipe AW 1.0 x 4m products savings of 33%, Target Pipe AW 2 ½ x 4m savings of 67%, Target Pipe C 5/8 x 4m savings of 67%, Target Pipe D 1 ½ savings of 50%, Target Pipe D 6.0 x 4m savings of 67%.</p> <p> </p>Dinda Eka Putri Ma'arifMuslimin Abdulrahim

<p><em>This study aims to measure the physical workload experienced by workers in Pegaraman 1 Sumenep, PT Garam (Persero). With a production of 115,000 tons per season, Pegaraman Area 1 Sumenep faces a huge challenge in achieving production targets with the use of efficient tools for workers. This is the problem that causes work fatigue, based on the identification of the research conducted. To overcome this problem, the research will focus on measuring the physical workload of salt loosening workers using the NBM, REBA, and CVL methods, in the hope of finding the right solution to solve problems related to work fatigue during the salt loosening process. The results showed that workers experienced physical workloads that needed action, with the results of the NBM recapitulation with a value of 50–70 risk levels, the REBA score with a value of 4, and CVL percentage values of 54.53% for the first worker, 55.21% for the second worker, and 53.67% for the third worker. Based on these findings, it can be concluded that the use of simple tools causes fatigue in workers. Therefore, an innovation is needed in the design of salt loosening tools to reduce the risk of fatigue in workers.</em></p>Moh. Subhan BasriHandy Febri Satoto

<p><em>Tri Jaya Sentosa is a marketing distributor for Frisian Flag dairy products. CV XYZ is located at Ds. Mojodeso, District. Cotton, Bojonegoro Regency. CV. Tri Jaya itself also often experiences a problem called the Bullwhip Effect in certain products. Demand from consumers often changes, so that sometimes it is difficult for companies to predict consumer demand, this situation often results in an increase or decrease in demand from consumers for a product. For this reason, an approach using Supply Chain Management (SCM) is needed. To overcome the problems that occur at CV. XYZ above, the author tries to provide a calculation solution to calculate, reduce and find out what causes the Bullwhip Effect. CV XYZ priorities for retail tend to experience a bullwhip effect. This situation ensures that product distribution is not constrained. CV XYZ priority is Tiga Bersaudara retail for BKM Sachet products because the bullwhip effect value is quite high, namely 2,825. This can mean that information distortion occurs so that information data from retail to sub-distributors does not run smoothly.</em></p>Alief Yoga RahargyansyahHerlina Herlina

<p><em>Kamun Dam is a permanent weir with its water intake in the Cilutung River Basin (DAS). One major factor affecting water reduction at the weir is sediment settling at the upstream base. Effective and efficient management is crucial for irrigation water and networks to maximize benefits. Water loss from primary to secondary and tertiary channels negatively impacts irrigation system performance. The water flow through weirs and structures with varying discharges influences the water surface profile and its characteristics.This research aimed to determine the water level, total sediment transport capacity, water discharge loss in the West Cilutung main channel, and the water surface profile shape. The data comprised primary data from field investigations and secondary data, including average discharge data from 2008-2017.Water level analysis was performed using hydraulic formulas and the Trial and Error method. The highest water level recorded was 0.74 m in April, and the lowest was 0.22 m in August. Sediment transport analysis, using the Meyer-Peter Muller method, estimated that it would take approximately 13 years to fill the upstream of Kamun Dam with 1,436,470.04 m³ of sediment, without dredging, given a river width of 74.15 m and height of 3 m. Water discharge loss analysis, using the inflow and outflow method, showed Qrenc results from BLK.1-BLB.1 at 0.06 m³/sec and Qactual at 0.27 m³/sec. The water surface profile analysis, using the graphical integration method, yielded Qrenc results for profile I f(y) = 4786 and Qactual results for profile I f(y) = 789</em></p>Erni Sari Lumban ToruanArief RijaluddinAsep Dian HeryadianaYoyo Sunarya

<p><em>This research evaluates the effectiveness of an AI-based fraud detection system in a finance startup using logistic regression methods. The primary objective is to assess whether this model is feasible for enhancing transaction security. The research methodology employed is quantitative, utilizing historical transaction data. The test results indicate that the logistic regression model can accurately predict the company's financial conditions, with an accuracy of 95%. However, there are challenges in detecting fraudulent transactions, as evidenced by the low recall for fraudulent transactions. The model evaluation was conducted using several performance metrics such as accuracy, precision, recall, and F1-score, as well as model fit tests including Hosmer and Lemeshow’s Goodness of Fit Test, Omnibus Test of Model Coefficients, and -2 log-likelihood. In conclusion, this model has the potential to enhance transaction security, but it still requires improvements to more effectively detect fraudulent transactions</em></p>M. Raflie AkbarKgs M.
