"Penelitian ini bertujuan untuk mengetahui faktor-faktor sosial demografi yang mempengaruhi pola permintaan pangan hewani (ikan, daging, unggas, telur dan susu) dan pengaruh perubahan harga dan pendapatan terhadap proporsi pengeluaran pangan hewani pada rumah tangga di Provinsi Sulawesi Selatan. Data yang digunakan dalam penelitian ini adalah data Survei Sosial Ekonomi Nasional (Susenas) tahun 2013 dengan melakukan analisis terhadap 13.018 sampel rumah tangga. Metode analisis adalah analisis deskriptif serta analisis ekonometrika menggunakan model Quadratic Almost Ideal Demand System (QUAIDS) dengan penduga Iterated Linear Least Square (ILLS).Penelitian ini menunjukkan bahwa konsumsi pangan hewani dipengaruhi oleh harga sendiri, harga komoditas lain, jumlah anggota rumah tangga, golongan pendapatan, wilayah tempat tinggal (perdesaan/ perkotaan), dan tingkat pendidikan kepala rumah tangga. Nilai elastisitas harga sendiri menunjukkan permintaan komoditas bersifat inelastis untuk ikan dan susu, sementara daging, unggas dan telur bersifat elastis. Berdasarkan nilai elastisitas harga silang, semua komoditi pangan hewani merupakan barang substitusi kecuali komoditi daging merupakan barang komplementer bagi unggas. Komoditi ikan dan telur termasuk barang normal sedangkan komoditi daging, unggas dan susu termasuk barang mewah.

The study was conducted to determine the socio-demographic factors affecting animal-based food demand (fish, meat, poultry, eggs and dairy) and the effect of price fluctuation and household income to expenditure share of animal-based food in South Sulawesi Province. The primary data for the study was National Socioeconomic Survey (Susenas) data in 2013. The study performed descriptive analysis and econometric analysis on 13.018 household samples. Quadratic Almost Ideal Demand System (QUAIDS) models with Iterated Linear Least Square (ILLS) estimator was applied for the econometric analysis.The study showed demand pattern of animal-based household food was affected the price of animal-based food, the price of other commodities, number of household member, income class, residential area (urban/rural), and education level of the household head. The price elasticity of animal-based food showed inelastic for fish and dairy; whereas meat, poultry and egg were tended to be elastic. Based on the cross-price elasticity, all animal-based food commodities substituted each other except for meat which was complimentary to poultry. Fish and egg were categorized as necessity goods, as for meat, poultry and dairy are categorized as luxury goods."

"Tujuan penelitian ini adalah untuk mempelajari pola permintaan daging di Indonesia. Penelitian ini menggunakan data survei rumah tangga SUSENAS tahun 2013 dan Sensus Pertanian (SP) 2013 yang dikeluarkan oleh Badan Pusat Statistik (BPS). Penelitian menggunakan pendekatanQuadratic Almost Ideal Demand System (QUAIDS) dengan estimator Iterated Linear Least Square (ILLS).Hasil analisis menunjukkkan bahwa terdapat pengaruh kota, pendidikan, ukuran rumah tangga, kelas pendapatan, dan suplai daging domestik terhadap pola permintaan dan elastisitas daging.

The objective of this study is to understand the meat demand pattern of household in Indonesia. This study used the 2013 National Socio-Economic Survey (SUSENAS) and Agriculrural Census (SP). The method used to understand the meat demand pattern is Quadratic Almost Ideal Demand System (QUAIDS) approach with Iterated Linear Least Square (ILLS) estimator.The result shows that urban, education, household size, and domestic meat supply have an influence on meat demand pattern and its elasticity."

"Penelitian ini membahas tentang manajemen persediaan barang MRO di Depo salah satu perusahaan transportasi berbasis rel yang baru komersil berjalan di Jakarta. Permasalahan terjadi pada masa-masa awal pengembangan dimana barang yang memiliki pola permintaan irregular memiliki potensi besar atas timbulnya biaya tambahan apabila belum dibentuk model persediaan yang tepat. Penilitian ini bertujuan untuk mendapatkan model persediaan yang memberikan total biaya minimal dengan variabel keputusan di dalam model yang optimal. Tahapan yang dilakukan dalam penelitian mencakup klasifikasi persediaan, peramalan, dan perhitungan variabel keputusan. Dengan menggunakan 3 model persediaan utama ((s,S),(R,S), dan (R,s,S)) yang memiliki metode penentuan variabel keputusanya masing-masing, hasil simulasi TPOP (Time Phased Order Point) terhadap 8 sampel item untuk perhitungan total biaya menunjukan penuruan sebesar 7% s.d 95% dari total biaya rencana pemesanan perusahaan

This study discusses about the inventory management of MRO goods in a Warehouse of Companys’s Depot, the object of this studies is one of the new commercial rail-based transportation companies running in Jakarta. Problems occur in the early days of development where goods that have irregular demand patterns have great potential for additional costs if an appropriate inventory model has not been established. This research aims to obtain an inventory model that provides a minimum total cost with the optimal decision variables. The research stages carried out in this study include: the classification of inventory model, forecasting, and calculation of decision variables. By using 3 main inventory models ((s, S), (R, S), and (R, s, S)) that have their respective decision variable determination methods, the results of the TPOP simulation (Time Phased Order Point) for total calculation the cost represents the reduction of 8 sample items at 7% to 95% of the total cost of the company ordering plan"
