Abstract

This research was conducted at one of the motorcycle dealers in Indonesia. Besides selling motorcycles, this dealer also provides services to repair motorcycles and sells genuine motorcycle parts. Inventory management which the company carried out is still not good enough because there are still demand for spare parts from consumers that cannot be fulfilled by the company. The purpose of this study is to draw up a plan to control spare parts by paying attention to the spare parts that need to be considered, estimating the exact number of spare parts demand, knowing the smallest total inventory cost, knowing the amount of safety stock needed, and knowing when to reorder. In preparing the spare parts control, the methods used are ABC analysis, demand forecasting method, and EOQ method. The results of this study are plans to control the inventory of Tire, Rr. such as the forecasting sales of Tire, Rr. as many as 17338, economic order quantity of Tire Rr are 2158 units, the number of safety stocks of Tire, Rr. needed in 2020 are 1738 units, and the reorder point in 2020 is 8 times with the total inventory cost for Tire, Rr. in 2020 is Rp. 30,009,005.

Abstract

Based on the initial discussion with people form Mosquito coil factory, there is a requirement to calculate the amount of waste from the factory. According to them, several wastes (in the form of liquid and solid waste) are produced in the process of making mosquito coils. The wastes are often scattered on the floor, causing the condition of the factory space to be unclean or dirty and can cause employees to get sick due to waste scattered on the floor. This research focuses on identifying the waste and to calculate the waste produced by each machine for the production of mosquito coils by using the Material Balance method. Material balance shows a quantitative analysis of material inputs, outputs and wastes / waste at each stage of the production process. Material balance calculation is done in the process of Sifting Coconut Shell Flour, Sifting Process for Coffee Skin Flour, Process for Sifting Wood Flour, Sifting Flour Sifting Process, Onggok Flour Cooking Process, Mixing Material into Mosquito Coe Dough, Mosquito Dough Sifting Process, Forming Process of Paste Paste Plate , The Process of Printing Paste Slabs Into Wet Double Coil, Drying Double Wet Coil Process, Drying and Separation Process of Baking Sheet with Dry Double Coil, Grinding Process of Broken Dry Double Coil, Process of Sifting Sweep Flour Falling on the Floor. Based on the observation, some of the waste obtained from each stage of the production process can be collected again and can be used again as a raw material for making mosquito coils.

Abstract

Salah satu ukuran performansi untuk menilai kecepatan pelayanan di IGD adalah waktu respon. Waktu respon adalah waktu antara pasien tiba di IGD hingga pasien ditangani oleh dokter IGD. Standar waktu respon berdasarkan Keputusan Menteri Kesehatan Republik Indonesia Nomor 856 Tahun 2009 adalah maksimum 5 (lima) menit. Penelitian ini bertujuan untuk menentukan jumlah kebutuhan sumber daya manusia (dokter dan perawat) di IGD RSU HKBP Balige sehingga waktu respon terhadap pasien menjadi lebih cepat dan sesuai standar. Metode yang digunakan pada penelitian ini adalah Discrete Event Simulation. Tujuan penelitian dicapai dengan membuat sebuah model simulasi IGD RSU HKBP Balige menggunakan perangkat lunak simulasi Arena dan melakukan eksperimen terhadap model simulasi tersebut. Hasil penelitian ini menunjukkan bahwa waktu respon rata-rata di IGD RSU HKBP Balige dapat diturunkan dari 8,61 menit menjadi 4,14 menit, serta waktu respon maksimum dari 26,30 menit menjadi 14,09 menit dengan penambahan sumber daya manusia sebanyak 2 dokter dan 3 perawat per shift.Kata kunci : pemotong, produktivitas, singkong, Metode Rasional.

Abstract

Ikan bandeng merupakan ikan yang memiliki kaya akan kandungan gizi. Ikan bandeng memiliki kandungan protein yang tinggi dan rendah lemak. Salah satu kelompok yang melakukan budidaya ikan bandeng yaitu kelompok tani tambak bungkak. Kelompok tani ini bergerak penyaluran distribusi pasokan ikan bandeng ke pedagang pengumpul dan industri pengolahan ikan. Permasalahan yang terjadi pada kelompok tani tersebut yaitu pengelolaan masih tradisional, produktivitas rendah serta risiko rantai pasok seperti harga, lingkungan yang berpengaruh pada proses keberlanjutan bisnisnya. Penelitian ini bertujuan untuk mengidentifikasi risiko-risiko dan melakukan pengendalian risiko pada rantai pasok ikan bandeng. Metode yang digunakan adalah ANP (Analytical Network Process) dan FMEA (Failure Mode and Effect Analysis). Kedua metode tersebut dilakukan integrasi sehingga diperoleh nilai WRPN (weighted risk priority number) untuk prioritas risiko untuk dilakukan perbaikan. Hasil penelitian diperoleh bahwa prioritas tertinggi yaitu risiko produksi dengan nilai WRPN sebesar 186,26. Pengendalian risiko yang dilakukan yaitu edukasi luas lahan budidaya ikan bandeng dan pemberian pinjaman untuk memperluas lahan, pembuatan waduk untuk penampungan air untuk mempermudah pengairan, dan pemberian nutrisi tambahan untuk ikan dan mengatur kondisi air
