Abstract

Strategic planning for the supply chain is part of the planning process for the supply chain management. One part of this process is figuring out the supply chain's infrastructure and physical structure. The design of supply chain networks has been used for facility location models for more than 20 years. The hub and spoke system is a two-level distribution network with a hub that handles shipments and spokes that connect with consumers. This study integrates optimization techniques with decision-making tools to determine  the best location for distribution centers. The optimization method is modified by considering population, income, and distance factors. The location of the distribution center is determined at two levels. The first level uses the set covering method, while the second uses the Analytical Hierarchy Process (AHP). A case study is drawn from this research: a company that will determine regional and local distribution centers in East Java. The result is four regional distribution centers: Pacitan, Kediri, Banyuwangi, and Sumenep. Each regional distribution center has two local distribution centers: Pacitan (Tulungagung and Madiun), Kediri (Bojonegoro and Jombang), Banyuwangi (Pasuruan and Malang), and Sumenep (Surabaya and Gresik). This study illustrates how the integration of two-level method can be applied in the context of strategic decision making. The selected locations have a minimum total cost and can serve consumers with maximum coverage in the region. Finally, an efficient supply chain network with a high service level will be obtained.

Abstract

Persaingan industri manufaktur di Indonesia semakin ketat, sehingga mendorong industri untuk berlomba-lomba meningkatkan kualitas produknya. PT. Jawa Metalindo Prima  adalah salah satu industri manufaktur yang memproduksi stud bolt, dimana masih sering ditemukan kecacatan dalam proses produksinya. Penelitian ini bertujuan untuk mengimplementasikan metode Six Sigma pada produksi stud bolt guna meminimalisir kecacatan produk dan meningkatkan kepuasan pelanggan. Metodologi ini didasarkan pada pendekatan Define, Measure, Analyze, Improve, and Control (DMAIC). Rata-rata hasil perhitungan nilai DPMO dan Sigma Level adalah 8696,02 dan 3,88, dimana masih belum dapat diterima karena masih jauh dari 6 sigma. Penyebab cacat tertinggi adalah ketidaksesuaian persentase perpanjangan dalam 4D yaitu sebesar 48%. Setelah dilakukan analisa, akar penyebab masalah produk cacat adalah operator yang kurang memiliki pengetahuan. Berdasarkan analisis 5W + 1H kebijakan yang harus diambil untuk meningkatkan kualitas stud bolt adalah selalu memperbarui work instruction dan melakukan pengawasan yang ketat pada setiap critical to quality.

Abstract

There are main activities of the worker in UD Askan such as splitting the fish, carrying, and lifting the tubs. Work activities are done manually and the production process continually undergoes. The frequency of activity (15 cycles) in a day causes the risk of fatigue, injury, and Musculoskeletal Disorders (MSDs). Evaluation of the work posture of four workers by Ovako Working Posture Analysis System (OWAS) and Job Strain Index (JSI) methods showed high risk in the process of lifting and carrying a tank. The previous posture caused the worker to bend forward, both legs standing or squatting with both knees, and walk by carrying a tub. The results recommend solving soonest due to the danger to the musculoskeletal. The recommendation shows that lifting methods are required and the design of lifting and transporting equipment is needed. The evaluation posture by OWAS show that the process of carrying a tank is 3 level (immediate repair because it is harmful to the musculoskeletal), and after improvement, it is 1 level (not harmful to the musculoskeletal). Then, JSI indicates any improvement from the 3 levels (posing a hazard) to level 1 (safe work).

Abstract

Sumenep’s hand Batik is one of best practice in Madura. Located in Pekandangan BaratVillage, Sumenep Regency. Production activities done manually and many hazards foundthroughout overall processes. The aime of this research is finding prediction model of safetywork behavior as the response by analyzing factors which influence safety work behaviorsignificantly. Observation executed by 80 respondents, the model used multivariate linierregression. The result obtained that knowledge variabel and protective personal equipmentare significant. Meanwhile, perception and communication are not significant. Finally, modelof safety work behavior found two variables such worker’s knowledge and protectivepersonal equipment which determination coeficient of model is 15.9%.
