The new policy issued by PT Pupuk Indonesia regarding the change of the responsible party for the procurement and the distribution of subsidized NPK fertilizers affected the subsidy allocation for PT Petrokimia Gresik, as the only company to conduct the procurement and distribution of the subsidized NPK fertilizer. It is now partially charged to the other holding members such as PT Kujang Cikampek, PT Pupuk Sriwidjaja, and PT Pupuk Kaltim. Also, all members of PT Pupuk Indonesia should face the reduction of subsidy allocation from Indonesia Government. PT Petrokimia Gresik also have to deal with Phonska V project plan in order to increase capacity of NPK fertilizer. Those policies are most significantlty impactful to the decrease of subsidy allocation in West Java. Besides, Central Java, a branch area of PT Petrokimia Gresik which has the biggest number of total capacity and fixed cost, should reevaluate the number and location of the buffer warehouse. This paper is aimed to explain the methodology using Mixed integer Linear Programming (MILP) in determining the optimal number and location of buffer warehouse in West Java and Central Java in response to the policies and the project plan. Firstly, the distribution system of NPK subsidized fertilizer are described. Next, previous researches about MILP and forecasting method applied in distribution system problem is explained. After that, related data and several conditions that are applied based on actual situation are shown. It can be deducted that MILP is an optimal method for the evaluation as it fits to the characteristic and condition of distribution system in PT Petrokimia Gresik.

―Design is a complex process where creativity and analytical skills are needed for success. At present, the development of design methods has moved towards field practice rather than theory. The main objective of this research is to determine the design of fast ferry to transport passengers from Sorong to other coastal areas in West Papua. The method used in this fast ferry design is the System Based Ship Design (SBSD) method which uses a strategy to reduce the number of loops to find the best concept by giving greater emphasis to the analysis of functions. The design study begins with a mission statement and establishes the main function requirements. Then find the area and volume needed on each deck that is determined by using life size experiment and model test experiment to determine the initial main dimensions. Then, alternatives to be evaluated against the relevant framework conditions.

The type of contract for the road project used in PT Pelabuhan Indonesia III (Persero) is currently using the type of General Contracting. The contract is conventional and is considered to have many weaknesses. To obtain more optimal project results and maintenance can run optimally, in addition to improving quality control by the project supervisory team, one way that can be done is to change the use of innovative types of contracts. namely Performance Based Contracts (PBC). When implementing the PBC for the first time, there are several things that must be prepared, one of which is the readiness of the owner and contractor. Analysis in this study uses Structural Equation Modeling (SEM). The results obtained are that the variable readiness to use PBC has a positive effect on the application of PBC. If the readiness variable increases by one unit and the other variables are considered constant then the PBC implementation variable will increase by 0.390. Keywords—Conventional Contracts, Performance Based Contract, SEM.
Pelabuhan Indonesia III (Persero)公路项目使用的合同类型目前是总承包类型。该合同是传统的，被认为有许多弱点。为了获得更优的项目结果和维护能够最优运行，除了由项目监督团队改进质量控制外，可以做的一种方法是改变使用创新类型的合同。即绩效合同(PBC)。在首次实施PBC时，有几件事必须准备好，其中之一是业主和承包商的准备情况。本研究采用结构方程模型(SEM)进行分析。结果表明，可变的PBC使用准备度对PBC的应用有积极的影响。如果准备变量增加一个单位，而其他变量被认为是恒定的，那么PBC实现变量将增加0.390。关键词:常规合同，履约合同，SEM。

— A dehydration unit using triethylene glycol absorption is a common process in natural gas processing. In its regeneration section, the regenerated lean glycol needs to be cooled before entering the glycol absorber, while the rich glycol is to be preheated before entering the regenerator. This is a good candidate for heat exchanger network (HEN) optimization. In this work, the HEN was revisited using pinch analysis (PA) and mathematical programming (MP) using superstructure. The optimized networks were evaluated using simplified total annual cost (TAC). The PA method using small Tmin (minimum temperature approach) led to the configuration of three exchangers, a heater and a cooler, with minimized utilities. At larger Tmin, the configuration became into two exchangers, two heaters, and a cooler. The minimum calculated TAC is $60,351/year at Tmin = 12.5 o C. Furthermore, it was revealed that one heater and one exchanger were two small. Therefore, they were omitted, and the heat load were redistributed to the network. The calculated TAC became $59,224/year. The superstructure approach resulted in two exchangers, a heater, and a cooler; with a calculated minimum TAC of $57,597/year. The two approaches have resulted in very similar minimized TAC.

⎯National fish consumption is increasing every year, both sea fish and fish farming. That is because the appeal and invitation of the government to consume fresh fish (white meat) which contains lots of vitamins and protein. Milkfish is one of the most consumed fish species because it is easy to get and the price is relatively cheap. One of the biggest milkfish producers in East Java is located in Gresik Regency. The fulfillment of milkfish consumption needs depends on its productivity. Milkfish productivity depends on the area of the pond. The greater the land area, the more milk fish can be produced. However, milkfish farming is often constrained by the size of ponds, so the amount of milkfish harvest is also limited. In this study, the goal programming method is used to obtain several objectives, namely maximizing profits, minimizing capital, minimizing production costs and inventory costs, taking into account the changing demands in each harvest period, population density, milkfish survival rate and growth rate. The profit from selling the harvest can be optimized by selling some fish (on demand) and re-raising the remaining milk fish from the harvest (inventory) for resale in the next harvest period. Although production costs and inventory costs increase with more food, these benefits will be maximized compared to selling the entire harvest during that period. Because the greater the weight of milk fish, the higher the selling price. So the benefits will be far more leverage. Keywords―Area of The Pond, Demand, Goal Programming, Growth Rate, Milkfish, Population Density, Survival Rate.

Abstrak —Dual channel supply chain is a combination of offline channel and online channel are running simultaneously as a new structure. Through online channels, consumers can find the best product prices. This is used by companies to implementing promotional prices to attract the attention of online consumers, one of them is by the flash sale program. Promotion aims to stimulate demand for a company’s product but along with the increase in demand is not always accompanied by an increase in profit. So it is necessary to consider the selling price of the product during the promotion and how long the promotion will be applied. This research is focused on determining the selling price of products and duration of the promotion as well as the impact using the help of Malpe software and Microsoft Excel. This study concluded that the lower price and the longer duration applied during the flash sale leads on the higher demand but will result in a decrease in profits. So that promotional strategies using the flash sale program can be applied if the company's main goal is only to increase the number of sales. price and duration of the flash sale so that sales through offline and online channels continue to run. Things to consider are the price of online channels when the flash sale program, the duration of the flash sale duration, and the effect of online channel prices during the flash sale program on changes in demand on both channels.
