"Sistem rantai suplai LNG di Indonesia menjadi bagian penting dan krusial dari seluruh bisnis proses LNG. Biaya rantai suplai mencakup sebagian besar dari harga jual LNG. Oleh karena itu, keberhasilan desain sistem rantai suplai akan mengurangi beban pihak pembeli dan pemberi subsidi. Tantangan yang ada saat ini adalah sistem distribusi yang belum merata ke seluruh wilayah di Indonesia, baik dalam bentuk LNG maupun listrik. Pada penelitian ini sistem rantai suplai akan difokuskan pada distribusi LNG ke Kawasan Indonesia bagian Timur, yaitu pada daerah kepulauan Maluku dan Papua. Penelitian dimulai dengan membandingkan demanddan supply dari listrik pada seluruh PLTMG di wilayah Indonesia bagian Timur dengan kondisi serta hasil produksi dari Kilang LNG, yaitu Tangguh dan Donggi-Senoro. Data yang diperlukan seperti kapasitas dan lokasi dari rute distribusi dalam sistem rantai suplai ke setiap pembangkit. Kemudian, peneliti membandingkan beberapa metode rantai suplai yang ada secara teoritis. Metode rantai suplai yang digunakan akan didefinisikan dalam variable optimasi berupa fungsi objektif dan fungsi batasan untuk memperoleh hasil maksimal. Output keluaran dari penelitian ini adalah rute serta biaya rantai suplai yang paling optimal dengan cara mendesain suatu sistem rantai suplai dengan software GAMS. Terakhir, hasil optimasi akan di analisa untuk membandingkan dengan teoritis.

LNG Supply Chain system has become one of the crucial parts in Indonesia's LNG business process. The overall costs of LNG products consist of the majority from the supply chain costs. Consequently, the successful of system design will decrease the burden for both first and third parties in the business. The optimal distribution system will provide an equivalent for all regions in Indonesia is the main challenge. This research will focus on the equality of electricity supply in the Eastern Region of Indonesia, Maluku, and Papua islands. Preliminary study begins with demand and supply side management will provide insights to balance between the LNG fields, Tangguh and Donggi-Senoro production allocation with the electricity power plants in Eastern Indonesia. The gap for data in the capacity and field facilities condition should be evaluated to help create the efficiency of supply chain systems. The second step is comparison between theoretical supply chain systems with the optimized system. The supply chain systems optimization output is the routing between regions and minimum costs for overall supply chain systems. In this research, we use the GAMS software to solve the optimization process. The final step is analysis for the optimized system for validation."

"The differences in interregional development have caused gaps in regions' advancements and prosperity, such as in the case of Western Indonesia (WI) and Eastern Indonesia (EI) and between urban and rural areas. The objective of this study is to analtze the structural path of road infrastructure construction sector on household income distribution change in both Intra and Inter West--East Region of Indonesia. The model used is Interregional social Acounting Matrix West abd East Region of Indonesia (IRSAM WEI). Within the model framework, construction sector is disaggregated into construction of road infrastructure sector (including bridge) and other construction sector. Meanwhile, the urban and rural household income is disaggregated into low, medium and high income. The structural Path Analysis (SPA) shows that the strongest multiplier effect comes from production factor of worker and capital before reaching households."

"Berdasarkan hasil SDKI 2017, angka fertilitas total di beberapa wilayah/provinsi masih cukup tinggi dan bahkan melebihi angka fertilitas nasional (2,4 anak per wanita), terutama di Kawasan Timur Indonesia. Selain itu, rata-rata Anak Lahir Hidup (ALH) pada kelompok wanita usia 40-49 tahun di hampir seluruh wilayah/provinsi Kawasan Timur Indonesia juga melebihi rata-rata ALH nasional, yaitu 2,8 anak per wanita. Dengan diketahuinya faktor-faktor yang berhubungan dengan jumlah ALH pada suatu kelompok WUS, khususnya pada kelompok wanita yang berusia 45 tahun ke atas, diharapkan dapat dapat menurunkan tingkat fertilitas di wilayah tersebut. Di mana, jumlah ALH rata-rata wanita pada akhir masa reproduksi (usia 45-49 tahun) akan memberikan informasi terkait ukuran keluarga lengkap (completed family size). Penelitian ini merupakan penelitian kuantitatif dengan menggunakan desain studi cross-sectional dan data yang digunakan pada penelitian ini yaitu, data sampel Survei Demografi dan Kesehatan Indonesia (SDKI) 2017. Penelitian ini menunjukkan bahwa dari 1055 wanita usia 45-49 tahun di KTI, 72,2% diantaranya mempunyai lebih dari 2 anak. Berdasarkan hasil uji regresi logistik berganda pada penelitian ini diketahui bahwa faktor umur kawin pertama, umur melahirkan pertama, pemakaian kontrasepsi, indeks kesejahteraan, mortalitas anak, dan jumlah anak yang diinginkan sebagai faktor yang berhubungan dengan jumlah ALH. Mortalitas anak dan jumlah anak yang diinginkan menjadi faktor yang paling berhubungan dengan jumlah ALH.

Based on IDHS 2017 results, total fertility rate in several provinces is still quite high and even exceeds the national fertility rate (2.4 children per woman), especially in Eastern Region of Indonesia. In addition, the average children ever born in the group of women aged 40-49 years in almost all provinces of Eastern Region of Indonesia also exceeds the national average of children ever born, which is 2.8 children per woman. By knowing the factors associated with the number of children ever born in a group of women of childbearing age, especially in the group of women aged 45 years and over, it is hoped that it can reduce fertility rates in the region. Where, the average amount of children ever born of women at the end of the reproductive period (age 45-49 years) will provide information related to completed family size. This study is quantitative study using a cross-sectional design and the data used in this study the 2017 Indonesian Demographic and Health Survey (IDHS) data. This study shows that out of 1055 women aged 45-49 years in Eastern Region of Indonesia, 72.2% of them have more than 2 children. Based on the results of multiple logistic regression tests in this study it is known that the factors of age at first marriage, age at first childbirth, contraceptive use, welfare index, child mortality, and number of desired children as factors associated with fertility (number of children ever born). Child mortality and the number of desired children become the most factors associated with fertility (number of children ever born)."
