Abstract

The main, current challenge to the maritime logistics system of Indonesia is the low level of freight transport from its eastern region. The transportation of goods to and from the eastern and western regions of Indonesia must be balanced if efficiency is to be enhanced and costs are to be reduced. One remedy to the current imbalance is increasing the existing economies of scale. This could be achieved by developing a hub port to enable goods to be consolidated and transported efficiently. The present study employs network analytics to determine the best site for a hub port in the eastern region of Indonesia. The coordinates of the ports in that region were analyzed using centrality algorithms and the NetworkX library. Based on analysis result, in perspective of relative distance between ports then Bitung port will be recommended as hub port in eastern Indonesia.

Abstract

Port Cluster is a collection of interdependent and involved companies in related activities in the same port area. Port clusters can be categorized as infrastructure. One of the characteristics of infrastructure is the number of parties involved in a problem, referred to as a Multi-Actor System. In a multi-actor system, policymaking becomes more complicated because it cannot be based on only one party's interests. Policymaking in this domain requires contemporary approaches where one of them is Simulation Gaming. This paper shows how Simulation Gaming can serve as an approach to comprehend the Indonesian Port Cluster, a multi-actor system.

Abstract

ABSTRAKANALISIS PROBABILISTIK PADA PERHITUNGAN BIAYA PEMBANGKITAN LISTRIK TERARAS PLTN. Keputusan strategis investasi pada proyek infrastruktur seperti PLTN menjadi sangat krusial dan memerlukan analisis yang mendalam, termasuk perhitungan keekonomian. Salah satu aspek dari keekonomian proyek pembangkit adalah perhitungan biaya pembangkitan listrik teraras atau Levelized Unit Electricity Cost (LUEC). Proyek PLTN sangat rentan terhadap sejumlah variabel ketidakpastian, oleh karena itu tujuan penelitian ini adalah untuk melakukan perhitungan LUEC PLTN dengan memasukkan sejumlah variabel ketidakpastian,yaitu dengan pendekatan probabilistik. Pada studi ini dilakukan analisis probabilistik dengan teknik Monte Carlo yang mensimulasikan keterkaitan di antara variabel-variabel ketidakpastian dan dilihat pengaruhnya terhadap LUEC. Hasil penelitian menunjukkan terjadinya peningkatan nilai LUEC pada pendekatan probabilistik dibandingkan dengan pendekatan deterministik (dari 9,8246 cent US$/kWh menjadi 11,1907 cent US$/kWh pada AP1000 dan dari 4,7413 cent US$/kWh menjadi 7,3321 cent US$/kWh pada OPR1000). Peningkatan nilai LUEC ini mencerminkan terjadinya dispersi akibat adanya beberapa variabel ketidakpastian yang mungkin terjadi dalam proyek, sehingga LUEC hasil analisis probabilistik ini disebut Risk Adjusted LUEC. Dengan analisis probabilistik dapat pula diketahui probabilitas terjadinya LUEC < 8,5 cent US$/kWh (nilai benchmark), yaitu sebesar 30% pada PLTN AP1000 dan 90% pada PLTN OPR1000.Kata kunci: ketidakpastian, analisis probabilistik, LUEC, PLTN, Monte Carlo ABSTRACTPROBABILISTIC ANALYSIS ON CALCULATION OF LEVELIZED UNIT ELECTRICITY COST (LUEC) OF NUCLEAR POWER PLANT (NPP). Strategic investment decisions on infrastucture project such as NPP development are crucial and require careful analysis, including economic calculation. One aspect of the project economic is calculation of LUEC. NPP project are vulnerable to a number of uncertain variables, therefore the purpose of this study was to perform calculations of NPP’s LUEC under uncertainties, namely probabilistic approach.In this study probabilistic analysis was done by Monte Carlo techniques that simulate the relationship between the uncertainty variables and visible impact on LUEC.The results showed an increase of LUEC value in probabilistic approach compared to deterministic approach (from US$ 9.8246 cents/kWh to US$ 11.1907 cents kWh in AP1000 and from US$ 4.7413 cents kWh to 7.3321 cents US$/kWh in OPR1000). The increase reflects the dispersion due to some uncertainty variables that may occur in the project,so LUEC of probabilistic analysis is called Risk Adjusted LUEC. With this analysis can also be known probability of LUEC < US$ 8.5 cent/kWh (benchmark value), ie by 30% in AP1000 and 90% in OPR1000.Keywords: uncertainties, probabilistic analysis, Monte Carlo technique, NPP

Abstract

The focus of this research is to analyze potential environmental impact in the utilization of carbon dioxide (CO2) as miscible gas injection on Enhanced Oil Recovery (EOR) activity. The reinjection of CO2 would reduce the amount of CO2 release in the air and is considered relatively as a new innovative approach. Responsible innovation (RI) is a research framework that considers aspects of sustainability both in terms of social, economic, and environmental toward an innovation made with five dimensions; reflexivity, deliberation, anticipation, responsiveness, and participation. However, RI does not have a specific quantitative approach to support the analysis. Therefore, this research proposes the use of simplified Life Cycle Assessment (LCA) as the quantitative analysis tool to support the RI analysis, using the case study of Subang Gas-Well, West Java, Indonesia. The case study has four main process units of CO2-Enhanced Oil Recovery, from the Well in Subang, CO2 Recovery, CO2 Transmission and the EOR Oil Well in Jatibarang. Based on the calculation, among the various impact categories, the biggest potential environmental impact is the contribution to acidification impact, followed by photo-oxidant formation, climate change and depletion of abiotic resources.

Abstract

As the largest archipelago nation in the world, Indonesia’s logistics system has not shown excellence according to the parameters of logistics performance index and based on logistics costs percentages from overall GDP. This is due to the imbalances of trading on the western and eastern regions in Indonesia, which impacts the transportation systems costs to and from the eastern regions. Therefore, it is imperative to improve the competitiveness of Indonesian maritime logistics through maritime logistics network design. This research will focus on three levels of decision making in logistics network design, which include type of ships in the strategic level, shipping routes in the tactical level, and container allocation in the operational level with implementing butterfly routes in Indonesia’s logistics networking problems. Furthermore, this research will analyze the impact of Pendulum Nusantara and Sea Toll routes against the company profits and percentages of containers shipped. This research will also foresee how demand uncertainties and multi-period planning should affect decision making in designing the Indonesian Liner Shipping Network.

Abstract

Indonesia sebagai negara kepulauan menghadapi tantangan dalam penyediaan akses internet bagi seluruh masyarakat, dimana saat ini masih terdapat banyak kabupaten yang belum tersedia akses internet. Sektor swasta tidak bersedia untuk menyediakan akses internet karena secara ekonomi kabupaten-kabupaten tersebut merupakan daerah tidak komersial, yang berarti mereka tidak akan memperoleh keuntungan namun sebaliknya akan rugi. Penelitian ini mengembangkan sebuah model konseptual dari kebijakan-kebijakan secara kualitatif yang akan mendorong penyediaan akses internet di kabupaten tersebut. Model konseptual menunjukkan hubungan antara kebijakan-kebijakan seperti regulasi tarif sewa, kewajiban pelayanan universal, regulasi subsidi dan regulasi perizinan yang akan mendorong sektor swasta untuk menyediakan akses internet. Model tersebut juga menunjukkan bahwa jumlah pengguna internet akan memberikan dampak positif terhadap Produk Domestik Regional Bruto (PDRB) dan Pendapatan Asli Daerah (PAD) yang pada akhirnya memberikan keuntungan bagi sektor swasta.

Abstract

The focus of this research is to analyze potential environmental impact in the supply chain of palm oil biodiesel industries. Simple Life Cycle Assessment (LCA) is applied to analyze impacts, produced by the three main units in the supply chain of Palm-Oil-based Biodiesel, which are Palm Plantation, CPO mill, and Biodiesel Plant. We developed LCA calculation model using spreadsheet software, used to assess a number of input scenarios to evaluate the best scenario, in variation of: land quality, land area and the rate of clearing, land clearing technique and type of the original land. The biggest potential environmental impact is the contribution to global warming impact which emissions are produced mostly from unit plantation. Although plantation has biggest potential to contribute to environmental impact, it also gives biggest reduction to global warming impact. In general, the biggest environmental impact in the LCA category is climate change, followed by photo-oxidant formation and eutrophication. The biggest impacts in the supply chain are from the plantation, especially when choosing the right technique for land clearing. In addition, due to LCA linearity nature, the scenario that we tested does not change the total accumulative environmental impacts.
