Abstract

PT Candi Jaya Amerta is a company engaged in the food sector and produces various types of traditional crackers, such as shrimp crackers, fish crackers, and other variations. The process of manually transporting flour raw materials at PT CJA takes a long time so that it can reduce the effectiveness of material handling. In this study, the design of an ergonomic raw material transport tool was carried out with the aim of reducing the level of fatigue in workers and speeding up the process of moving raw materials. the method used is the anthropometric method. the results of collecting anhtropometric data on workers are used to design the tool. the cardiovascular load method is used to measure the level of fatigue of workers based on the pulse rate of workers. the dimensions of the tool have a height of 114cm, width of 80cm, length of 125cm, and tool reach of 88cm. the percentage of worker fatigue is known with % CVL before using the tool design. worker 1 = 72.5%, worker 2 = 61.22% then there is a decrease in fatigue levels after using the tool design to %CVL worker 1 = 43%, worker 2 = 26%.

Abstract

The sambel pecel grinding machine is a machine used to smooth the ingredients of sambel pecel. The ingredients for making sambel pecel consist of fried peanuts, brown sugar, red chili, garlic, lime leaves, and other ingredients. All these ingredients will be ground to make sambel pecel. UMKM pecel and rujak coffee shop 58 in the process of grinding sambel pecel still requires services from other places, so that condition causes the production process to be less efficient. The purpose of this research is to make a sambel pecel grinding machine part of the transmission system.The results of the design of the resource and transmission parts of the sambel pecel grinding machine are: the resource used is an AC electric motor with a power of 0.268 Hp and a rotation speed of 2900 rpm, the transmission used is a pulley and a type A V-belt to drive the grinder, the diameter of the drive pulley used is 65 m, the driven pulley is 130 mm, the length of the V-belt circumference is 711 mm, number of belts required 1 piece, and uses a WPA 40 gearbox with a ratio of 1: 20.

Abstract

Efficient logistics management plays a crucial role in the success of EPC projects, particularly when transporting heavy fabricated components across island regions. This study aims to identify the most optimal transportation mode using the AHP based on six key criteria: cost, lead time, risk, load capacity, flexibility, and port accessibility. A hierarchical decision model was developed and assessed by seven expert respondents, with calculations performed using Expert Choice 11. The results indicate that cost, lead time, and port accessibility hold the highest priority weights, reflecting their strategic importance in EPC logistics. The synthesis of criteria and alternative weights identified Roll-on/Roll-off (RoRo) as the most suitable transportation mode, outperforming cargo ships, barges, LCTs, and truck combinations. Validation using actual project data further confirmed this result: the total delivery cost using RoRo amounted to IDR 1,126,000,000, representing a 22% savings compared to the planned budget, and only 1.66% of the total project cost significantly lower than industry benchmarks of 8–11%.  The results confirm that AHP constitutes an effective and reliable approach for transportation mode selection in EPC projects. The study offers actionable managerial insights and advances the application of multi-criteria decision-making in construction logistics.

Abstract

Sumber daya manusia merupakan elemen krusial dalam keberlangsungan proses produksi, karena jumlah tenaga kerja yang sesuai dengan beban kerja akan berpengaruh langsung terhadap produktivitas, kualitas produk, serta efisiensi biaya operasional perusahaan. Penelitian ini dilakukan di PT Kasa Husada Wira Jatim, sebuah perusahaan yang bergerak di bidang produksi alat kesehatan, dengan tujuan menentukan jumlah tenaga kerja optimal pada proses produksi kasa lipat. Penentuan kebutuhan tenaga kerja dilakukan menggunakan metode Work Load Analysis (WLA), yang mampu mengukur beban kerja aktual berdasarkan waktu rata-rata, standar deviasi, kecukupan data, serta performance rating dari setiap elemen kerja. Elemen-elemen yang dianalisis mencakup proses penerimaan bahan baku, pemeriksaan kualitas, pemotongan, pelipatan, hingga tahap pengemasan. Seluruh tahapan tersebut diukur secara sistematis untuk memperoleh gambaran akurat mengenai waktu baku yang dibutuhkan dalam menyelesaikan setiap aktivitas produksi. Hasil penelitian menunjukkan bahwa seluruh data telah memenuhi batas kecukupan sehingga valid untuk digunakan dalam perhitungan kebutuhan tenaga kerja. Berdasarkan analisis waktu baku dan tingkat beban kerja, diperoleh jumlah tenaga kerja optimal yang diperlukan guna mencapai target produksi dengan efisiensi maksimal. Temuan ini memberikan gambaran penting bagi perusahaan dalam menyusun strategi pengelolaan sumber daya manusia yang lebih efektif, adaptif, dan berkelanjutan. Selain itu, penelitian ini dapat dijadikan referensi dalam meningkatkan produktivitas serta memastikan kualitas produk tetap terjaga melalui penataan tenaga kerja yang tepat dan terukur
