Abstract

Frequently, decision making in company management is faced with multiobjectives and its contradiction where need to be minized in order to receip a maximum profit. Problem of promotion costs alocation of speedy services product in Ambon has a relation with an increasing sales volume policy (customer numbers) through many kind of promotion. It can, in a one side, raise company incomes, and at the other side, multiply promotion costs. The problem is formulated as a goal programming model to provide an optimal cost allocation decision. By running it in WinQSB software, we find number of allocation for each alternative: Rp. 35.005.000 (alternative I), Rp. 31.681.248 (alternative II), Rp. 28.357.504 (alternative III), while other costs are Rp. 48.850.000 (promotion material cost), Rp. 29.800.000 (merchandise cost), dan Rp. 6.000.000 (exhibition cost). The results also show 2.022 as the lowest customer number and 4.632 as the highes one.

Abstract

Every marine and naval architectur indusrties need to produce a ship at a more low cost to maintain themselve as a strong, independent and competitive company. This can be realized by organizing the use of production machines to minimize the total production cost. The research is conducted to detect the use level of production machines from economics view by using break even analysis method. Results show the level of company expendeture at Rp. 12.796.909.00, income at Rp. 13.149.400.00 and profit at Rp. 325.491.

Abstract

In this paper, a new symmetry argument in a vacuum state with strictly vanishing vacuum energy has been studied. This argument exploits the well-known feature that deSitter and Anti-deSitter space are related by analytic continuation in complex analysis. When we drop boundary and hermiticity conditions on quantum fields, we get as many negative as positive energy states, which are related by transformations to complex space. In this case, we have explored indirectly a new perspective to solve cosmological constant problem.

Abstract

Dried Eucheumacottoniiseaweed (DES) is one of the main aquaculture commodities in Indonesia. Local farmers plant, harvest, and dry the seaweed, and subsequently sell it to traders. The selling price of seaweed depends on internal and external factors. To maximize their profit, farmers have to estimate the future price development by means of these factors. This paper presents a novel data-driven method reports on our attempts to develop methods to aid farmers in making such predictions. More specifically, we apply data mining to the task of predicting the seaweed price eight weeks ahead, at the time of selling. The data mining algorithm, i.e., classifier, requires attributes as its inputs. In our experiments, we selected three internal and three external factors as input attributes. The internal-factorattributes used are: current price, dirty content, and moisture content. The three external-factor attributes all relate to the weather and areminimum temperature, maximum temperature, and precipitation. All attributes are measured at time t. The output of classifier is a binary classification indicating if the seaweed sales price at time t plus eight weeks is larger or smaller than the price at time t. The data is collected from two publicly available sources and consists of 275measurements of six attributes each.We evaluated the performances of four classifiers on our data set using 10-fold cross-validation. The results obtained revealed that we were able to predict the selling price of seaweed with an accuracy of64%. Analysis of the trained classifier revealed that the main attribute used for predicting the future price is the current price. In conclusion, our data mining experiments suggest that it is feasible to predict the future price development of seaweedselling pricein Indonesia with accuracy above chance level.

Abstract

Accident of KM. Putri Ayu at June 17, 2012 in sea of Asilulu, Ambon Island-Maluku, leaving of problem: what its cause factor?; how its contribution?; and what its step to prevent similar accident in future? This research have the character of analytic descriptive, as a mean to explain about factors cause of accident of sea transportation with analyse at occurence of KM. Putri Ayu, and also invite stakeholders to be more comprehend in importance security and safety of sea transportation and generated risk effect of anticipatory negligence of factors, also repair recommendations to stakeholder in others sea transportation. Output of analysis indicated there are 3 (three) factors have contribution in accident KM Putri Ayu, that is (1) negligence of regulator; (2) technical condition of ship; and (3) weather is extreme. For that, utilize to guarantee its form of safety and reliable ship security system in Moluccas, te future : (1) Improving cooperation in between crew of ship, owner and regulator; ( 2) Improving maintenance system of ship; and ( 3) Existence of comprehensive analysis to condition of every sea transport.

Abstract

An internal-combustion engine is a reciprocating type of engine in which the working substance is a mixture of gases produced by combustion of fuel in the engine cylinder. A diesel or compression-ignition engine is a machine with self-ignition engine of fuel and internal mixing. The working cycle of a diesel engine can also be completed in two strokes of the piston. The mixture of gases produced upon the combustion of the fuel in the cylinder of the engine forms the working substance which presses against the piston and does work. The pressure and temperature at the principal points that characterize the working cycle of a diesel engine can be determined from formulas of thermodynamics with account taken of the thermochemical processes that take place in the engine.

Abstract

Banyaknya jumlah konsumen harian dari Nakamura Seitai menyebabkan fasilitas yang ada kurang memadai untuk mendukung pelaksanaan jasa pijatnya. Areal sekitar lokasi industri ini sudah padat dan sulit untuk pengembangan. Pihak manajemen memutuskan membuka cabang baru di wilayah Kota Ambon dengan mempertimbangkan 3 alternatif lokasi yaitu Urimessing, Batu Meja, Tanah Tinggi, dan Passo. Penilaian masing-masing lokasi menggunakan metode wawancara berdasarkan perspektif pemilik perusahaan. Kriteria umum seleksi lokasi adalah ukuran lokasi, biaya investasi, pasar, bahan baku, dan infrastruktur pendukung. Analisis data menggunakan metode analytical hierarchy process (AHP) menunjukkan Urimessing mendapatkan prioritas tertinggi dari pemilik perusahaan sebagai lokasi pembangunan cabang baru industri pijat tersebut.
