Abstract

Kota Sabang merupakan salah satu destinasi favorit di Indonesia yang terletak di Pulau Weh. Berlokasi di ujung barat Provinsi Aceh dan terpisah dari daratan utama membawa pengaruh keterbatasan terhadap kebutuhan hidup masyarakat. Satu diantaranya adalah air minum, dimana permasalahan di Pulau Weh adalah air tanah yang tersedia mengandung ‘karang’ menurut warga setempat. Guna mengatasi isu tersebut, maka dibutuhkan pendekatan berbasis teknologi tepat guna. Kegiatan pengabdian masyarakat ini bertujuan untuk mengimplementasikan teknologi Reverse Osmosis (RO) sebagai solusi kebutuhan air minum di Kota Sabang. Proses RO dalam sistem pengolahan air minum sudah umum diaplikasikan dalam dunia industri, namun dalam kesempatan ini mesin diletakkan dalam ruang publik guna mendukung peningkatan kualitas pariwisata khususnya wisata halal. Pemasangan alat di Masjid Babussalam Kota Sabang diharapkan mampu memberikan pengalaman unik bagi wisatawan dalam menikmati wisata halal, selain itu dapat dijadikan sebagai program sedekah air minum yang bermanfaat bagi masyarakat yang berkelanjutan.

Abstract

The development of the inventory model started when Harris introduced the classic inventory model. It was firstly published by Wilson using the optimization method. He derived a mathematical equation model to obtain economic order quantities. Later, this model is known as the classic Economic Order Quantity (EOQ) or Wilson Model. The classic inventory EOQ model has some limitations. The model assumed that order items do not have physical changes during a planning period. This assumption becomes the weakness of the classical EOQ inventory model. Many items have material changes during a planning period, such as amelioration, deterioration, and growth. This research proposed a new mathematical model. The model relaxes three implicit assumptions of the classical EOQ: (1) the ordered items do not grow; (2) unlimited capacity; and (3) unlimited budget. A solution procedure to solve the model was developed and illustrated with a numerical example. A numerical example was performed to compare the result between the reference model and the new model. The number of ordered items per cycle time increased by 7%, and cycle time increased by 28%. It increased because the proposed model tends to choose large purchased quantities to get a cheap price. It caused the number of ordered items per cycle time to be larger and the cycle time to be smaller than the reference model. This research also provided sensitivity analysis. It showed the response of decision variables to some changes in input parameters.
