Abstract

Para mahasiswa mencoba mencari kegiatan yang sifatnya dilakukan bersama antara beberapa denominasi gereja dan memberikan manfaat secara langsung bagi lingkungan gereja dan masyarakat umum di kemudian hari. Dari hasil diskusi, akhirnya para mahasiswa memutuskan untuk membuat kegiatan workshop menjahit di kalangan kaum wanita di lingkungan PGIS kota Cirebon. Kota Cirebon adalah kota penghasil kain batik, salah satu yang menjadi ikon dan banyak dikenal oleh masyarakat adalah batik motif “mega mendung”. Batik ini bila di bila dijual langsung, harganya menjadi murah dan minatnya juga terbatas kalau dijual dalam bentuk kain. Bila dijual dalam bentuk produk jadi fashion (baju, celana, asesoris seperti tas, dompet, topi) akan sangat mungkin diminati oleh banyak orang dan tentunya ada nilai tambah di harga jual.

Abstract

The problem in this research is the lack of research that shows traditional musical instruments in Central Kalimantan in the form of visualization (images) and elaboration with culture, maintenance space and also religion, which is basically applicable and useful for the maintenance of property, culture, philosophical values contained therein. This research method is qualitative research with data search through visualization of images or camera shots of the authors directly to the source of traditional musical instruments in Palangka Raya. The results show that diversity, Indonesianness through gotong royong, instrument maintenance, culture and religion are inextricably intertwined as a space for diversity and religiosity and at the same time as a further elaborative space to explore musical instruments with something that enriches art.

Abstract

One of the manufacturing companies engaged in agribusiness, one of which is processing cooking oil, often occurs damage to goods due to excess stock of goods and increases expenses for storage costs. Before carrying out the production process, the company must forecast demand to find out how much the estimated raw material needs will be used as inventory control so that there is no excess or shortage of stock that will harm the company. The purpose of this study is to predict the amount of cooking oil demand in the next 12 periods, plan the lot size of raw materials with the lowest cost and determine the right time to order raw material supplies. The method used in forecasting is Autoregressive Integrated Moving Average (ARIMA) and lot size planning with Materials Requirements Planning (MRP) FOQ and POQ techniques. ARIMA forecasting results with a MAPE value of 33% and the lowest cost technique chosen by POQ
