Abstract

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.

Abstract

Kualitas lampu pijar secara umum ditentukan dari parameter terangnya lampu, bentuk bola lampu, dan bentuk filament yang berpijar saat lampu menyala. Jika lampu pijar pada tahap jauh dari ketiga kriteria tersebut maka lampu dikatakan tidak berkulitas dan dinyatakan reject. Penelitian dilakukan pada mesin exhaust departemen produksi lampu pijar PT GE Lighting Indonesia, data yang digunakan adalah jumlah produk jadi dan produk cacat di mesin exhaust, serta Faktor-faktor yang menyebabkan terjadinya kecacatan. Pengolahan data dilakukan dengan cara menghitung tingkat dan peluang kecacatan, menghitung DPMO, membuat paretto diagram, dan Fishbone diagram. Nilai sigma dari mesin exhaust berada pada kisaran 4,6 σ, nilai ini cukup bagus untuk proses produksi namun perlu ditingkatkan melalui perbaikan-perbaikan lain secara terus-menerus. Kecacatan paling banyak dijumpai pada mesin exhaust adalah patah poli dengan prosentase 69,8%. Faktor utama penyebab kecacatan adalah setting mesin yang kurang tepat dan bagian poli sendiri rapuh karena suhu pembakaran dari proses sebelumnya kurang tepat.

Abstract

Climate change which is triggered by a consumptive human culture continues to be a concern for many parties to be tackled. Shoes have become the primary need of urban communities because of their function that cannot be separated from their daily activities. Shoes that are purchased by consumers are usually packaged in cardboard boxes that follow the components of the contents, namely the shoes and accessories inside. In this case, shoeboxes with the right design and function according to consumer preferences will reduce the likelihood that the shoeboxes are thrown into the trash. Although it is not the centre of consumer attention, shoe boxes remain a necessity in the final production process. It is necessary to design and develop a shoebox product that is in accordance with the final function of the shoebox according to consumer interests. This study uses the QFD method which produces quality 1 houses with communication tools in the form of a preliminary questionnaire to 30 respondents and a follow-up questionnaire to 100 respondents. Concept selection was carried out on the eight alternative concepts developed. The shoebox concept chosen to take into account the desires of the consumer will be made with a sporty shoebox standard size of 22.5 x 12.3 x 32.5 cm. The environmentally friendly shoebox can be seen through the installation of plastic straps which are expected to reduce the use of single-use plastics. In addition, the shoebox is made with an innovative design so that users can use it repeatedly as shoe storage or multipurpose box.

Abstract

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.

Abstract

PT. Harpa Inti Mandiri adalah perusahaan yang memproduksi Tas Kulit dengan merek dagang Alra. Penentuan harga pokok produksinya pada saat ini dengan cara mengitung rata – rata total biaya kebutuhan produksi, sehingga berakibat harga pokok produksi belum akurat. Penelitian ini bertujuan untuk menentukan harga pokok produksi yang lebih akurat yakni dengan menggunakan job order costing, sehingga diharapkan memberi kemudahan dalam menentukan kebijakan penentuan harga jual dengan biaya pabrikasi bersih. Hasil penelitian diperoleh harga pokok produksi tas handle besar sebesar Rp 672.988,00/pcs dengan harga pokok produksi sebelumnya adalah Rp 474.321,00/pcs dengan selisih Rp 153.667,00/pcs. Harga pokok produksi tas dennis sebesar Rp 544.829,00/pcs dengan harga pokok produksi sebelumnya adalah Rp 346.161,00/pcs dengan selisih Rp 198.668,00/pcs. Harga pokok produksi tas tomson sebesar Rp 615.988,00/pcs dengan harga pokok produksi sebelumnya adalah Rp 417.321,00/pcs dengan selisih Rp 198.667,00/pcs.

Abstract

Kalasan Fried Chicken Industry Center is one of the home industries producing fried chicken in Yogyakarta. Initial measurements obtained from the working environment conditions of occupational health and safety are still considered to be less than comfortable and in accordance with standards. As a result of lack of lighting and high room temperature, workers often experience eye fatigue, dizziness, frequent loss of focus and poor quality fried chicken production. Occupational health and safety according to the standard, it is necessary to improve the lighting aspect with the Lumen Method (Lumen Method or Zonal Cavacity Method, ZCM), the physical environment in terms of temperature is designed by increasing the fan capacity needed by the work environment so that the number and type of fans with quality can be determined the right air for the room. The lighting needs of the work environment are 9 24 watt lights and an exhaust fan and sufficient air volume. The results of the implementation were able to increase the level of lighting and temperature in accordance with work comfort.
