Percetakan XYZ merupakan salah satu UMKM yang memproduksi tulisan atau gambar untuk kepentingan periklanan, salah satunya adalah spanduk. Percetakan tersebut mempunyai beberapa permasalahan terkait kondisi kerja serta belum adanya kesadaran dalam menerapkan Keselamatan dan Kesehatan Kerja (K3) di tempat kerja. Tujuan penelitian ini adalah melakukan evaluasi kondisi kerja serta merancang usulan perbaikan untuk kondisi kerja yang lebih produktif dan sesuai dengan pedoman K3 di percetakan XYZ. Program Work Improvement in Small Enterprises (WISE) dengan pendekatan Participatory Action Oriented Training (PAOT) dilakukan dengan melibatkan partisipasi aktif dari pemilik usaha serta pekerja dalam melakukan evaluasi kondisi kerja, pembuatan rencana aksi perbaikan serta implementasi usulan perbaikan. Hasil evaluasi kondisi kerja menggunakan daftar periksa WISE, menunjukkan terdapat 13 elemen periksa yang membutuhkan suatu usulan perbaikan. Melalui metode focus group discussion (FGD) didapatkan hasil bahwa perbaikan yang akan diprioritaskan untuk diimplementasikan dalam waktu dekat adalah 4 elemen periksa karena mempertimbangkan faktor biaya, waktu, dan sumber daya manusia di lapangan. Perbaikan pertama adalah pembuatan jadwal rutin untuk pemeriksaan mesin serta jaringan kabel listrik dengan penerapan 5R. Perbaikan kedua adalah pembuatan tanda bahaya pencegahan kebakaran. Perbaikan ketiga adalah pembuatan tanda himbauan pemakaian pelindung diri masker dan sarung tangan. Perbaikan keempat adalah pembuatan label untuk menuliskan identitas produk sehingga memudahkan pekerja mengenali produk yang berada di area penyimpanan. Evaluasi serta usulan perbaikan kondisi kerja tersebut dapat membantu UMKM dalam meningkatkan kesadaran akan K3 dan mengurangi risiko terjadinya kecelakaan kerja.

Sustainable manufacturing aspects are environmental, economic, and social. These aspects can be applied to an optimization model in the machining process. An optimization model is needed to determine the optimum cutting parameters. This research develops a multi-objective optimization model that can optimize cutting parameters on a multi-pass turning. Decision variables are cutting parameters multi-pass turning. This research has three objective functions for minimizing energy, carbon emissions, and costs. Three functions are searched for optimal values using the GEKKO.  A numerical example is given to show the implementation of the model and solved using GEKKO and Interior Point Optimizer (IPOPT). The results of optimization indicate that the model can be used to optimize the cutting parameters.

Abstract. Temperature monitoring apparatus is required for the distribution of certain products that

Location and routing are the main critical problems investigated in a logistic. Location-Routing Problem (LRP) involves determining the location of facilities and vehicle routes to supply customer's demands. Determination of depots as distribution centers is one of the problems in LRP.  In LRP, carbon emissions need to be considered because these problems cause global warming and climate change. In this paper, a new mathematical model for LRP considering CO2 emissions minimization is proposed. This study developed a new  Mixed Integer Linear Programming (MILP)  model for LRP with time windows and considered the environmental impacts.  Finally, a case study was conducted in the province of Central Java, Indonesia. In this case study, there are three depot candidates. The study results indicated that using this method in existing conditions and constraints provides a more optimal solution than the company's actual route. A sensitivity analysis was also carried out in this case study.

Supply Chain Management is a relationship between related components in a company. The relationship between the complex components of supply chain needs to be measured and evaluate the performance so it can be increased by effectively and the company can run the business properly. Case studies conducted in newspaper industry, supply chain cycle in the newspaper industry is less than 24 hours. In this research use simulation to supports making desicion through analyzing the system of the supply chain. The newspaper supply chain was simulated using the system dynamics software. SCOR model used as a tool to speed up the simulation modelling of supply chain. This research was conducted to make the model simulation of performance measurement in newspaper industry started in 2019 to 2022. The final results obtained for the Reliability attributes associated with Perfect Order Fulfillment is 99,59%. Responsiveness attributes associated with the Order Fulfillment Cycle Time about 3.3 hours from the target 4 hours. The Cost attributes was about 80.81% refers from total of material, production, and transportation cost divided by the sales. Agility attributes of upside flexibility about 3.3 hours and upside adaptability about 120.22% by the capacity of the machine. Assets Management attributes with cash to cash cycle time is about 27 days.
