Abstract Increasing the population in Kota Bangun Sub-District, Kutai Kartanegara Regency, in line with the consequence that growing needs for drinking water and raw water for local communities become a top priority. Public complaints about the increasing difficulty of obtaining clean water seem to be an obstacle that the Regional Government has yet to resolve fully. The production capacity of PDAM Kota Bangun is currently only 30 liters/sec, which is far from sufficient for the needs of all people in the Kota Bangun Sub-District. Economic feasibility calculation analysis utilized the NPV, IRR, and BCR methods and sensitivity analysis to obtain the economic feasibility for the value of developing intake and raw water networks. The results indicate, with a reasonable life condition of 30 years, the construction of water networks in Kota Bangun is still economically feasible. Reasonable with the minimum requirement of BCR = 1, with sensitivity analysis on two scenarios, considerations of 30% and 20% leakage, and 30.55% and 25% administrative costs. The results of the research show that IRR = 17.70%. If the analysis conditions are that investment costs increase by 10% with Fixed Benefits, the payback period is 6.8 years.

Calculation Analysis

UKM Jovelyn is a small medium enterprise (SME) that engaged in the field of bakery production. Until now, they produce cakes and cookies. They sell products throughout the Batam area which includes (Tiban market, aviari market, mitra market and puja bahari market), shops, school canteens and so on. The SME targets several things such as profit per month, number of hours worked, number of overtime hours, machine utilities, labor utilities and so forth. Until now, the SME has not been able to reach  the targets because the UKM has not determined the production amount based on the appropriate calculation. The number of products made is determined only on an intuitive basis. Determination of the amount of production cannot be determined by the usual simplex method because the objective function in the usual simplex method contains a target. Problem solving is done by using goal programming. The results of the calculation analysis show that to achieve the optimal value, the SME must produce coconut root cookies, butter cookies, nastar cookies, snow princess cookies and peanut cookies respectively 11.89 kg, 22.43 kg, 24.96 kg , 1.97kg and 0 kg. Sensitivity analysis is carried out after there are changes in conditions that result in changes in the linear program matrix, so the number of products that must be made also changes which include coconut root cookies as much as 12.8 kg, as much as 16.91 kg of butter cookies, nastar cookies as much as 25.7 and the last is 3.39 kg of nut cookies which in the initial calculation, nut cookies were not produced. The sensitivity analysis is not done by recalculation but rather by modifying the matrix and completing iteration with primal dual.

Tight Oil Reservoirs

The CO2 huff-n-puff is an effective substitute technology to further improve oil recovery of natural fractured tight oil reservoirs after water flooding, for its high displacement efficiency and superior injectivity. The CO2 huff-n-puff process is influenced by many factors, such as miscible degree, complex fracture networks, and production schemes. What is worse, those influence facts affect each other making the process more complex. Many researchers concentrated on mechanisms and single sensitivity analysis of CO2 huff-n-puff process, whereas few optimized this process with the consideration of all influence factors and multiobjective to get favorable performance. We built multiobjective consisted of miscible degree, oil recovery, and gas replacing oil rate considering the aspects of CO2 flooding special characteristic, technical effectiveness, and economic feasibility, respectively. We have taken Yuan 284 tight oil block as a case, firstly investigated sensitivity analysis, and then optimized CO2 huff-n-puff process using orthogonal experiment design with multifactors and multiobjectives. The optimization results show CO2 huff-n-puff can significantly improve oil recovery by 8.87% original oil in place (OOIP) compared with water flooding, which offers guidelines for field operations.

Abstract In view of the growing importance of distributed generation, the pluralization of the energy matrix close to large consumption centers has become necessary. In this sense, the energy sector can contribute to electricity generation using waste products such as vinasse, the most relevant in terms of volume and polluting capacity. The general objective of this article is to analyze the economic feasibility of using vinasse for electricity generation, and as a specific objective, to identify the viable price range of MWh in free and regulated energy environments and the productive capacity of plants for this type of investment. The methodology used was quantitative research, based on the cost structure of a biodigester IC internal combustion engine with 38% yield and vinasse logistics according to the production capacity of autonomous plants of 100 m3, 1,000 m3, and 3,000 m3ethanol/day for scenarios with and without tax exemptions for a price range between US$ 26.04 and US$ 130.20/MWh. The analysis shows that the use of vinasse for electricity generation is restricted to medium and large producers. Furthermore, the price of MWh is more relevant than the tax exemption for the feasibility of this type of project. This corroborates the constant requests from the sugar-energy sector to hold exclusive electricity auctions for biomass, given its cost structure and its social, economic, and environmental externalities.

Crude Palm Oil

In recent years, there has been an increase in crude palm oil (CPO) demand, resulting in palm oil mills (POMs) seizing the opportunity to increase CPO production to make more profits. A series of equipment are designed to operate in their optimum capacities in the current existing POMs. Some equipment may be limited by their maximum design capacities when there is a need to increase CPO production, resulting in process bottlenecks. In this research, a framework is developed to provide stepwise procedures on identifying bottlenecks and retrofitting a POM process to cater for the increase in production capacity. This framework adapts an algebraic approach known as Inoperability Input-Output Modelling (IIM). To illustrate the application of the framework, an industrial POM case study was solved using LINGO software in this work, by maximising its production capacity. Benefit-to-Cost Ratio (BCR) analysis was also performed to assess the economic feasibility. As results, the Screw Press was identified as the bottleneck. The retrofitting recommendation was to purchase an additional Screw Press to cater for the new throughput with BCR of 54.57. It was found the POM to be able to achieve the maximum targeted production capacity of 8,139.65 kg/hr of CPO without any bottlenecks.

Subject Kirkuk oil. Significance The issue of control of Kirkuk's oil is moving to the centre of Baghdad's economic deal with the Kurdistan Regional Government (KRG). KRG forces took full control of the city and some of the province's oil fields in the wake of the federal army's collapse in July 2014. In need of significant rehabilitation, the fields' current production of 320,000 barrels per day (b/d) is well below the 475,000 b/d production capacity estimated by the US Energy Information Agency (pre-2003 levels were 900,000 b/d). However, a fiscal crisis and lower oil prices mean that Kirkuk oil is now a key issue in talks on revenue-sharing between Baghdad and Irbil. Impacts The KRG could escalate further by seizing all of Kirkuk's oilfields, which might speed up exports of Kirkuk oil. The Kurds will control Kirkuk militarily for the foreseeable future. Broken Baghdad-KRG relations could slow down the liberation of Mosul.
