PT. Adi Satria Abadi bergerak pada industri pembuatan sarung tangan kulit, perusahaan akan mengidentifikasi faktor – faktor yang mempengaruhi keefektifan mesin dan analisis terhadap aktivitas maintenance untuk bahan masukan dalam penerapan Total productive maintenance (TPM). Penelitian bertujuan mengukur tingkat efektivitas peralatan total proses produksi, menentukan faktor penyebab nilai Overall Equipment Effectiveness (OEE) rendah dan mengidentifikasi kerugian/losses yang terjadi, memberikan usulan perbaikan penerapan TPM. Nilai Overall Equipment Effectiveness (OEE) mesin press atom periode Maret 2015 – April antara 45% - 86% masih dibawah standar nilai Overall Equipment Effectiveness (OEE) dengan penyebab oleh performance ratio rendah antara 47% - 88%. Perusahaan dapat mengetahui efektifitas mesin dengan perhitungan tingkat keefektifan peralatan menggunakan Total Productive Maintenance (TPM) berdasarkan nilai Overall Equipment Effectiveness (OEE), sehingga dapat meningkatkan efektivitas peralatan serta mengeliminasi kerugian besar bagi perusahaan yang dikenal dengan six Big losses.

Usaha Kecil dan Menengah telah bertumbuh dan berkembang pesat di Indonesia. Di Kabupaten Bantul terdapat pusat kerajinan kipas yang berada di Dusun Jipangan, Kelurahan Bangunjiwo, Kecamatan Kasihan. Proses produksi yang terdapat pada UKM ini masih sangat sederhana sehingga tingkat produktivitasnya pun juga rendah. Oleh sebab itu, pemilik ingin menaikkan kemampuan produksinya dengan mengganti proses pengiratan dengan teknologi yang baru yang memiliki kemampuan produksi yang lebih tinggi. Dengan demikian, perlu dilakukan pemilihan alternatif teknologi yang baru sesuai keinginan pemilik UKM. Selanjutnya dilakukan penerapan ergonomi makro berdasarkan pendekatan sistem sosioteknik untuk merancangan sistem kerja yang baru dengan mempertimbangkan keinginan teknologi dari pemilik UKM. Pada penelitian ini, pemilihan alternatif teknologi menggunakan metode Analytical Hierarchy Process (AHP). Pemilihan alternatif yang tepat nantinya akan berdampak pada desain sistem kerja yang baru. Penelitian ini bertujuan untuk membuat desain ulang sistem kerja yang diinginkan untuk meningkatkan produktivitas dengan penerapan ergonomi makro yang menggunakan pendekatan sistem sosioteknik dari pemilihan alternatif yang terpilih. Berdasarkan hasil penelitian ini, telah diperoleh 6 kriteria dengan 15 sub kriteria yang dapat digunakan untuk pemilihan alternatif teknologi. Kriteria-kriteria tersebut diantaranya keahlian operator, upah operator, biaya, peningkatan fungsi, mudah digunakan, dan kenyamanan. Dari hasil perhitungan, didapatkan alternatif teknologi terbaik yaitu teknologi otomatis dengan bobot sebesar 0,658. Kemudian didapatkan desain sistem kerja yang baru yaitu dengan spesifikasi tenaga kerja dengan pendidikan minimal Diploma, melakukan pengadaan mesin irat bambu, serta lingkungan yang dekat dengan bahan baku, supplier, dan area pemasaran dan juga dengan tingkat produktivitas untuk penggunaan alternatif teknologi otomatis sebesar 0,019%.

CV Tunas Jaya Abadi adalah perusahaan yang memproduksi kotak makan (wooden lunch box) berbahan baku kayu sengon laut (albasia). Produk yang dihasilkan berukuran 165 x 118 x 1,7 mm dan 193 x 118 x 1,7 mm. Proses produksi yang dilakukan adalah make to order repetitif. CV Tunas Jaya Abadi memiliki permasalahan dengan kapasitas produksi yang menyebabkan pesanan tidak terpenuhi. Lantai produksi terdapat stasiun kerja bottleneck pada stasiun kerja sanding/penghalusan. Penumpukan tersebut terjadi karena perbedaan waktu standar dan kapasitas maksimum pada stasiun kerja sebelumnya. Penelitian ini digunakan metode Theory of Constraints (TOC) untuk mengatasi stasiun kerja yang mengalami bottleneck. Perhitungan kapasitas maksimum setiap stasiun kerja didapat hasil bahwa stasiun kerja 7 memiliki kapasitas lebih sedikit dibanding stasiun kerja sebelumnya. Pemecahan masalah bottleneck pada stasiun kerja 7 terdapat dua alternatif solusi, yaitu dengan overtime atau penambahan shift kerja. Setelah dianalisis dari permasalahan yang ada maka untuk mengatasi bottleneck pada stasiun kerja 7 dilakukan penambahan shift kerja dari 1 shift menjadi 3 shift kerja. Hasil dari penambahan shift kerja ini tidak terjadi bottleneck pada stasiun kerja 7.

The packaged beverage industry with various brands has appeared on the market. The number of competitors in the market requires the packaged beverage industry to implement the right strategy to win the competition. One strategy that can be applied is to make savings and maximize the use of company resources. One of the savings that can be done is to minimize production costs, while maximizing the use of resources can be done by maximizing the utility of the machine owned by the company. Efforts to minimize production costs can be contradictory to efforts to maximize machine utility, this is because maximizing machine utility will certainly require additional production costs, even though the company also wants to minimize production costs. This is included in the category of multi-criteria decision-making problems. To facilitate the company's management in achieving these contradictory company goals, this study will develop a multi-criteria decision-making model to assist companies in making optimal decisions regarding these contradictory company goals. The multi-criteria decision-making model developed is a mathematical model consisting of two mutually contradictory objective functions, namely minimizing production costs and maximizing machine utility, as well as problem constraints which are limitations that are owned by the company in optimizing the achievement of these contradictory company goals. To optimize the multi-criteria decision-making model that has been developed, it will use the global criterion method. The global criterion method will produce a compromise solution that has a minimum deviation from the ideal value of each objective function. Using the global criterion method, a production plan that minimizes production costs and maximizes machine utility is obtained. The multi-criteria decision-making model developed will cause the production plan to have a small deviation from the actual demand, because the model development involves forecasting product demand. The developed model will also produce a production plan that will not exceed the warehouse capacity, so that product storage costs can be minimized, this is because the developed model includes warehouse capacity as a barrier.

Goat milk powder is one of the perishable processed products. The decreasing quality of goat milk powder can cause financial losses to the company if not regulated properly. So far, the company is also faced with the problem of consumer demand uncertainty. When demand for powdered goat's milk is high, the company experiences stockout but can be overcome by backorder. When demand is low, there will be overstock. Overstock conditions, in addition to causing high holding costs, are also at risk of product quality degradation or expiration. In this study, an inventory model of goat milk powder was developed that considers the uncertainty of demand, product quality, and backorder to determine the optimal production quantity so that the total inventory cost incurred is minimum. The basic model used is economic production quantity. Uncertainty in demand and the percentage of products declining in quality is approached using a triangular fuzzy. While the defuzzification technique used is signed distance.

Make To Order (MTO) is a manufacturing strategy that executes different orders based on consumer demand. In the MTO strategy, products are produced only when there are orders from consumers. In this MTO system, the production process starts when an order arrives and starts with planning raw materials which takes a long time and causes a long lead time (MLT). Long MLT often causes production delays and forces companies to pay more overtime. Companies must adopt a production system that can fulfill a variety of orders and has a fast response time. In this research, a case study was conducted on a shoe and bag manufacturing company in the fashion industry. This study aims to implement a mass customization manufacturing (MC) strategy to minimize MLT. The MC strategy uses the concept of a production process based on orders and inventory. This study is expected to reduce MLT so that production delays do not occur again. The results of this study indicate that relocation of the customer order decoupling point (CODP) can reduce MLT from 30 days to 26 days. By reducing this, production delays can be overcome. In terms of costs, this production system is lower than before and the profits are higher.
