Abstract

The climate in Ambon, are influenced by sea climate and season climate, cause of this island arrounded by sea, it is make very high rainfall intensity. A very high collinearity between independent variables, make the estimate can not rely be ordinary least square method so it market with not real regretion coefficient and the collinearity. Collinearity can be detected by linier correlation coefficient between independent variables and also with VIF way. Regretion principal component analysis is used to remove collinearity and all of independent variable into model, this analysis is regretion analysis technique wher eare combinated with principal component analysis technique. The object of this analysis is to simplify the variable by overcast it dimension, we can do it removes the correlation between coefficient by transformation. Regresion can help to solve this case rainfall in Ambon on 2010. So the colinearity to independent variables can be overcome and then we can get the best regretion rutes.

Abstract

Bagian yang cukup penting dalam sistem jalan tol adalah plaza tol yang merupakan tempat pelayanan dan pembayaran sebelum masuk tol. Plaza tol biasanya terdiri dari beberapa jalur sehingga memudahkan proses pembayaran dan pelayanan. Pengelola plaza tol harus memberikan pelayanan yang terbaik kepada pengguna jalan tol, sehingga salah satu masalah yang dihadapi adalah bagaimana meminimumkan waktu tunggu dan biaya operasional. Penelitian ini bertujuan untuk mendesain model optimasi plaza tol dengan menggunakan Mixed Integer Non Linier Programming (MINLP). Dari hasil yang diperoleh dapat ditentukan kombinasi yang tepat dari berbagai tipe jalur agar penggunaan masing-masing jalur optimal sehingga bisa meminimalkan waktu tunggu dan biaya operasional tiap jalur.

Abstract

By learning and researching the wave-length of light and its propagation we can make an observation of the function and effectiveness light as a stimulation in fishing.The purposes of the observation are: to know how the color of light lamp influences to the result of fishing; to observe how the depth of location for fishing influences the reduction of light intensity; to know what is the relation between parameter condition/ atmosphere (salinity, temperature and transparency of the water) with the result of fishing.The observation is applied with a direct observation method in water of Batu Dua- Ambon Island.The total result of fishing is 57.2 kilograms with applied for us different light lamp (red, yellow, green and blue). Each color applied has the result: the red light lamps got amount of 4.5 kg; the yellow light lamps got amount of 15,1 kg ; the green light lamps got amount 17.4 kg; and the blue light lamps got amount of 20.2 kg.Data analysis statistically using an analysis of variance system which indicates that the stimulation light lamp influences to the result of fishing.Result of the statistical observation shows that parameter conditions/ atmosphere in the water, such as salinity. temperature, transparency of the water, such as: salinity, temperature, transparency of the water do not influence to the result of fishing.

Abstract

Dalam Jurnal ini dibahas masalah sistem even diskrit yang ada pada Automated Manufacturing System (AMS), khususnya menyangkut model, kedinamikan, danmendesain sistem AMS dengan menggunakan tool matematik Petri net. Selanjutnya dikonstruksikan suatu model AMS yang komponen utamanya terdiri dari dua entry, duaexit, lima mesin, dua buffer, empat robot, dan dua sistem Automated Guided Vehicle (AGV) yang ada dalam AMS, dimana masing-masing komponen tersebut memiliki deskripsi kerjaberlainan sesuai tugas masing-masing. Dengan menggunakan metode hybrid, AMS akan ditransformasikan ke dalam tool matematik Petri net dengan menggunakan deskripsisintesis yang didalamnya terdiri atas dua prosedur kerja yaitu top-down design dan bottomup design. Dekomposisi (decomposition) dan penghalusan (refinement) yang meliputipenambahan place shared dan non-shared resource ke dalam Petri net dibutuhkan untuk mendapatkan desain Petri net AMS yang akan mengurangi atau menghilangkan deadlockpada sistem AMS. Dengan demikian, suatu definisi dari hybrid sintesis serta struktur Petri net dapat terjawab. Perilaku mendesain sistem ini akan dibahas untuk mendapatkan suatudesain yang efektif dalam fungsi dan penggunaan AMS tersebut.

Abstract

This paper was a review about theory of Henstock integral. Riemann gave a definition of integral based on the sum of the partitions in Integration area (interval [a, b]). Thosepartitions is a  -positive constant. Independently, Henstock and Kurzweil replaces - positive constant on construction Riemann integral into a positive function, ie (x)>0 forevery x[a, b]. This function is a partition in interval [a, b]. From this partitions, we can defined a new integral called Henstock integral. Henstock integral is referred to as acomplete Riemann integral, because the basic properties of the Henstock integral is more constructive than Riemann Integral.

Abstract

Dengue fever is an infectious tropical disease caused by the Dengue virus. Dengue haemorrhagic fever constitute a substantial health burden on world's population. In thisresearch, an application of optimal control theory to Dengue epidemics using MISER3 was presented. The dynamic model is described by a set of nonlinear ordinary differentialequations, that depend on the dynamics of the Dengue mosquito, the number of infected individuals, and people's motivation to combat the mosquito. The cost functional dependsnot only on the costs of medical treatment of the infected people but also on the costs related to educational and sanitation campaigns. We observe that with currentcomputational tools it is easy to obtain, in an efficient way, better solutions to Dengue problems, leading to a decrease in the number of infected mosquitoes and individuals inless time and with lower costs.

Abstract

Infant mortality is an experienced child death before the age of one year. Regression analysis is a statistical analysis that aims to model the relationship between responsevariables (Y) with predictor variables (X). If the Poisson distributed response variables (Y), the regression model used was Poisson regression. The purpose of this research is to get aPoisson regression model according to the significant factors that influence the infant mortality. The results shows that the significant factors are influence the infant mortality asthe presentation of non medical childbirth (X1) and quantity of medical facility (X7). The case studies are infant mortality in Provinsi Maluku in 2010.

Abstract

The has already designed temperature and humidity measurement devices using SHT11 sensor with display results in Liquid Crystal Display (LCD). Manually, the environmenttemperature was measured using a mercury thermometer and the environment humidity was measured by a hygrometer. The results were observed in analog and it often misread thus it caused errors in ready the data. To solve the problem, then were made a design temperature and humidity measuring devices digitally. The processor of this tool is ATMega16microcontroller that processes analog input signals to obtain a digital output. Temperature and humidity sensors SHT11 were used, the measurement results and read digital displayon the LCD. This design produced temperature and humidity measurement, aids accurately, it was ± 0.4 ° C and ± 3%.

Abstract

Suli hot springs area has a low level of acidity or neutral pH ranges (7,2–7,7). It is also supported by a high chloride concentration value, which ranges (208,87-226,27) ppm. Thisshows that the area on station 1, 2, 3, and 4 are located in areas with water flow into the upper reservoir (upflow) and belongs to hot water domination reservoir tipe (water heatedreservoir). Reservoir temperature is calculated by the formula geotermometer (SiO2)p considered whether applied in the four kinds geotermometer equation because it gives the calculation results are not much different temperature and has a value of rms-error is less than 2%. Reservoir temperature at a hot springs station Suli possible temperature (161 ± 0,9)oC. Reservoir temperature at station 2 hot spring Suli possible hot water temperature (172 ± 1,0)oC. Reservoir temperature at station 3 hot springs Suli possible temperature (171 ±0,9)oC. Reservoir temperature at station 4 hot springs Suli possible temperature (169 ± 1,0)oC.
