Abstract

Supplier merupakan suatu entitas dalam rantai pasok yang memegang peranan penting untuk menjaga ketersediaan bahan baku sebuah industri manufaktur. Pada bagian pengadaan, aktivitas pemilihan supplier akan mempengaruhi kinerja perusahaan dan kepuasan konsumen. Pabrik X merupakan salah satu perusahaan pembuat boneka yang menggunakan kain acrylic sebagai bahan baku utama dan memiliki 6 supplier yang dapat memasok bahan baku tersebut. Saat ini, supplier yang memasok bahan baku tidak memenuhi standar kualitas perusahaan dan sering tidak dapat memenuhi jumlah bahan baku yang diinginkan perusahaan. Pabrik X ingin menentukan ulang prioritas supplier yang memasok kain acrylic. Metode yang digunakan dalam pengambilan keputusan adalah Analytic Network Process. Penelitian ini dimulai dengan wawancara dan penyebaran kuesioner dalam penentuan kriteria dan sub-kriteria. Proses pengolahan data menggunakan software Superdecisions yang telah divalidasi. Hasil pengolahan data menunjukkan bahwa jumlah kriteria tidak mengalami perubahan yaitu 5 kriteria dengan urutan kualitas, harga, pelayanan, pengiriman, dan respon dengan bobot berturut sebesar 0,309; 0,254; 0,226; 0,152; dan 0,057. Jumlah sub-kriteria bertambah dari 10 subkriteria menjadi 16 sub-kriteria dengan urutan yang memiliki pengaruh yang besar adalah kualitas bahan baku, kecepatan menanggapi pesanan, kemampuan memenuhi pesanan, moda pengiriman, dan harga bahan baku. Prioritas utama supplier mengalami perubahan menjadi PT QLL.

Abstract

Distribusi produk di sepanjang rantai pasokan, yang secara langsung mempengaruhi biaya rantai pasokan adalah key driver dari profitabilitas perusahaan secara keseluruhan. Biaya distribusi bahkan menyumbang sekitar 30% dari biaya produk. Oleh karena itu, masalah distribusi merupakan pertimbangan penting untuk perusahaan industri yang memiliki jaringan rantai pasokan. Penelitian ini mempertimbangkan masalah distribusi dua tahap dari rantai pasokan yang dikaitkan dengan biaya tetap. Dua jenis biaya terlibat dalam masalah ini adalah biaya berkelanjutan yang meningkat secara linier sesuai dengan jumlah produk yang dikirim antara sumber dan tujuan serta biaya kedua adalah biaya tetap yang terjadi setiap kali jumlah yang tidak nol dikirimkan antara sumber dan tujuan. Tujuan yang ingin dicapai adalah meminimalisasi total biaya distribusi. Metode heuristik konstruktif sederhana yang didasari oleh metode aproksimasi Vogel akan dievaluasi untuk kualitas dari solusinya dengan membandingkannya dengan solusi yang dihasilkan dari metode genetika (GA) dan sebuah metode heuristik lain. Hasil perbandingan menunjukkan bahwa metode heuristik tersebut memiliki solusi yang baik dan dapat dipertimbangkan untuk digunakan dalam praktik. Metode heuristik tersebut dapat diselesaikan dengan perhitungan yang cukup sederhana dan membutuhkan waktu yang cukup singkat.

Abstract

During the pandemic period, many people work from home, so work facilities are needed that could support the implementation of their work. However, the body also needs to be kept healthy to stay in shape, for that exercise is needed. The technique used in design development is the Design Thinking method focusing on the integration of user needs. The use of this technique is done by collecting some input obtained from users who are still working from home during the pandemic. Work and exercise that is done in a house that has a limited area that becomes an obstacle. Therefore, it is necessary to design a work facility that also functions as a sports tool, so that it does not require a large room space in the house. The results of the research are in the form of a proposed work facility consisting of a table, chair that can be adjusted in height, and sports equipment which includes a stationary bicycle, arm swivel device, jogging plate, and stepper. the design of the work facilities is made considering the ease of installation and convenience to be carried everywhere (portable) and comfortable when used.

Abstract

The relayout of the production facilities needs to be carried out by a manufacturer if there is a new product produced that has a different material flow from the existing product. If the layout of the initial facility is maintained, the material flow will become irregular and lead to long material transfer distances and substantial material handling costs. One method that can be used for relayout production facilities is the fractal method. This method is suitable for job shop system because it could provide a high level of flexibility and low total material handling costs. The case study used in this research, which is a spare part manufacturer that initially applied the by-process layout. The initial layout is less flexible in line with the current manufacturing conditions where there are additional variations in the types of products produced. The distance between machines with different types becomes far apart. By relayout of the production facilities using the fractal method, the material handling cost savings of IDR 157,868.64/week or 60.75%/week and the total savings in moving distance is 186,365 meters/week or 38.93%/week. Fractal method is proven to be used to design the layout of production facilities and reduce material handling costs and material transfer distances.

Abstract

During the pandemic of Corona Virus Disease 2019 (COVID-19) that hit Indonesia, all activities were very limited. Electrical Engineering Study Program of Universitas Kristen Maranatha was motivated  to share knowledge especially in the field of science about "Basic Unity and Virtual Reality (VR)" to the public. This has been realized through community service activities pursued by students and lecturers. VR refers to computer simulations that create images of the world that appear in human senses, in the same way as humans perceive the real world in reality. This community service used the Participatory Action Research (PAR) approach. From the results of a survey of community service activities that have been carried out, it is concluded that the success in providing mentoring to improve the ability of the community to use Basic Unity and VR online, is shown by the results of an increase in the score from an average of 5.85 before the activity, to 7.58 (from a total score of 10) after the activity. The community service committee team's service during the activity was also considered very good and worthy of being maintained in subsequent activities. Meanwhile, the implementation of providing teaching materials, the readiness of the trainers, and the implementation of organizing activities online, still need to be re-evaluated and improved in the future for better results.

Abstract

Consumer satisfaction with a product could be determined based on several factors including quality, price, and fast distribution. Distribution activity is one of the important activities because it guarantees that products are circulated properly, do not accumulate in warehouses, and delivered on time. For micro, small and medium enterprises (MSMEs), distribution arrangements could provide significant savings in distance and distribution costs so as to increase profits. Besides that, distribution arrangements could also guarantee that products are delivered on time to consumers. This resarch uses a simple distribution determination method, the Savings Matrix method, followed by the Nearest Insert, Nearest Neighbour, and Farthest Insert heuristic algorithms. The purpose of this research is to help MSMEs that have the main distribution process to be able to arrange their distribution routes so that deliveries could be made on time and at minimal cost. In this research, a numerical example was used of a plastic equipment MSME which had problems with late delivery and the occurrence of round trips so that it became inefficient. In addition to determining the distribution route, four scenarios are also given for MSME to consider thus the distance and cost savings obtained are more significant. From the results of the calculation of determining the distribution route, it is found that the Savings Matrix method and the Nearest Neighbour heuristic method provide savings of around 12,82% or IDR 698,550 per month.

Abstract

The distribution or delivery process is one factor that affect customer satisfaction as the goal of supply chain. In order for supply chain to be competitive in competition, delivery time is an important factor to manage, so that it could provide high service level value. One factor that could affects distribution or delivery is distribution center location. A strategic distribution center location would facilitate and speed up distribution process. This research discusses model for determining location of distribution center so that delivery could be made at the right amount and in the right time by analyzing of time-based using set covering model and maximal covering model. The numerical example in this research is case study on paint supply chain in Bandung which has a number of delivering clusters. Each cluster consists of a number of building material stores which are located scattered. There is one cluster that has problems in fulfilling demands and delivery times. The analysis made could be used to determine the distribution center location so that it could serve all consumer demands. Based on the calculation results, it was found that there were two distribution center locations. Two distribution centers could fulfill the objective function of cost minimization and satisfy all demands. The results of the sensitivity analysis show that there are several factors that influence the determination of location number.

Abstract

Stroke could cause paralysis and reduced body function. In an effort to self-mobilize, a stroke patient needs a wheelchair. Even though the existing wheelchairs have undergone significant development, both in terms of design and technology, the function of these wheelchairs is still limited, to assist users in carrying out their daily activities and there is no wheelchair that functions as a wheelchair. therapy tool. One way to recover from a stroke and help prevent further disability is therapy, both medical therapy and alternative therapy. Therefore, in this study a wheelchair was designed to function as a therapeutic tool by making circular movements carried out by the arms, hands and legs as well as movements away from and towards the chest carried by the arms and hands so that the muscles could be strengthened, thus helping the recovery process from stroke, especially those that attack the hands and feet of stroke sufferers. The method used in the design is design thinking that focuses on humans, knowing user needs, and innovating according to user needs. The design thinking process consists of 5 stages: empathize, define, ideate, prototype, and test. In its design, wheelchairs are also made to consider ease of installation and use.

Abstract

Pabrik mie Ho Kie San merupakan sebuah UMKM yang berlokasi di Kecamatan Patikraja, Kabupaten Banyumas, Jawa Tengah. Pabrik ini memproduksi mie tradisional yang terdiri dari mie halus dan mie kasar. Pabrik mengalami masalah dalam menentukan jumlah operator produksi, khususnya di bagian packing. Hal tersebut dikarenakan salah satu proses dalam pembuatan mie adalah pengeringan, dimana proses ini sangat bergantung dengan cuaca. Apabila cuaca hujan, maka proses pengeringan akan terhambat. Akibatnya hasil pengeringan yang akan dikemas menjadi sedikit. Hal tersebut menyebabkan jumlah operator packing terlalu banyak dan target produksi juga tidak tercapai. Oleh karena itu dilakukan kegiatan pengabdian kepada masyarakat (abdimas) untuk membantu mitra dalam menentukan jumlah operator produksi yang optimal pada tiap stasiun kerja agar kapasitas produksinya dapat meningkat. Metode yang digunakan adalah konsultasi dan pelatihan. Tahapan yang dilakukan meliputi konsultasi awal tentang kondisi di pabrik, perhitungan waktu baku, penyusunan peta proses operasi, perhitungan kapasitas produksi saat ini, penyeimbangan lintasan dengan strategi paralleling dan perhitungan jumlah operator yang optimal, pembuatan program spreadsheet, pelatihan, dan evaluasi. Kegiatan ini dilaksanakan pada tanggal 19 Oktober-21 Desember 2022. Mitra sasarannya adalah pabrik mie Ho Kie San, dimana peserta yang mewakili mitra ada 1 orang, yaitu dari bagian Human Resource Development. Berdasarkan hasil konsultasi dan pelatihan diperoleh jumlah operator yang dibutuhkan, sehingga kapasitas mixing yang semula 1,43 ton/hari meningkat menjadi 2,09 ton/hari (peningkatan 46,15%) dan kapasitas packing yang semula 0,4-0,67 ton/hari meningkat menjadi 1,55-1,63 ton/hari (meningkat 138,81%-287,75%). Hasil dari pelatihan tersebut diharapkan dapat membantu pabrik dalam menyelesaikan permasalahan yang dihadapi, sekaligus juga meningkatkan kapasitas produksinya. Ho Kie San is a Micro, Small, and Medium-scale Enterprise (MSME), which takes place in Patikraja District, Banyumas Regency, Central Java. The factory produces traditional dried noodles with two different cut sizes, fine and coarse. The factory found an issue determining the optimal number of operators on the shop floor, especially in the packaging station. This is because one of the processes in making noodles is drying, which is very dependent on the weather. If it rains, the drying process will be hampered. Consequently, the results of drying to be packaged are small. This causes the number of packing operators to be too many, and the production target is not achieved. Therefore, community service activities are carried out to assist partners in determining the optimal number of production operators at each workstation to increase production capacity. The method used is consultation and training to determine the optimal number of operators at each workstation. The steps done involve 1) consultation, 2) standard time calculation, 3) operation process chart construction, 4) existing production capacity calculation, 5) line balancing by paralleling and calculating the optimal number of operators, 6) spreadsheet formulation, 7) training, and 8) evaluation. This activity was held on 19 October-21 December 2022. The target partner is the Ho Kie San noodle factory, where 1 participant represents the partner from the Human Resource Development division. Based on the results of consultation and training, the number of operators needed was obtained, so that the mixing capacity, which was originally 1.43 tons/day, increased to 2.09 tons/day (an increase of 46.15%) and the packing capacity, which was originally 0.4-0.67 tons/day increased to 1.55-1.63 tons/day (an increase of 138.81% -287.75%). The outcomes of the training provided are expected to help the factory solve the issues of idle time and increase its production capacity.
