The study related to the size and the exploitation rate of Shortfin scad are important in order to see the development condition of resource, especially on stock availibility for the management of its sustainability. This study was conducted in April - September 2013 at The Fish Landing Base (PPI) of Sorong, West Papua. This study aims to analyze the biology aspects of Shortfin scad based on itss length frequency, length-weight relationship, growth rate, mortality rate and exploitation rate of the catch.The primary data was acquired by the measurement of length and weight of Shortfin scad landed by purse seiner and from interview with the fishermen. The number Shortfin scad measured during reseach was 1.504 individuals which classified by the size of class interval, the data then analyzed to see the length-weight relationship and growth rate parameter analysis (LÂ¥and K) by using the program of FAO-ICLARM stock of the assessment tools II (FiSAT II). The results showed that the frequency and normal distribution of total length, midlength is dominated by class interval of 16,0 - 16,5 cm. The correlation between weight and length of the individual is not significantly differ with the value of b = 3,57 (positive allometriks). The length (Loo) and weight asymptotic (Loo) are 21,83 mm and 105,4 grams respectively, this is allegedly estimated that the age of Shortfin scad is approximately of 40 months or 3.3 years. The result of exploitation rate acquired from the comparison between the mortality rate of catch and total mortality (E = F / Z) is 0,35. This indicating that the exploitation rate of Shortfin scad (Decapterus macrosoma) in purse seine fisheries  at the time of research is still small due to smaller value compared to the optimal value when F = M or E = 0,5.

Cadangan Bahan Bakar Minyak (BBM) khususnya bensin semakin berkurang dan tidak dapat diperbarui lagi sementara kebutuhan semakin bertambah dan akan berdampak pada krisis energi. Penelitian ini mengkaji penggunaan Liquefied Petroleum Gas (LPG) sebagai bahan bakar alternatif pengganti BBM jenis bensin untuk mengoperasikan motor bensin siklus empat langkah. Penelitian ini dilakukan dengan memodifikasi pada bagian karburator menjadi saluran masuk untuk gas LPG. Percobaan yang dilakukan meliputi uji operasional, uji ketahanan operasi yang dilakukan hingga 100 jam operasi dengan memberikan variasi jumlah bahan bakar yang diberikan sebesar 3 Psi dan 4 Psi. Hasil penelitian ini menunjukkan bahwa LPG jenis campuran dapat digunakan sebagai bahan bakar alternatif pengganti BBM jenis bensin 4 tak.

The purpose of this study is to obtain a formula for Islamic Education in the perspective of al quran. The results of the study found that Character in an Islamic perspective is nothing but morality. Noble character is the fruit that results from the process of applying sharia (worship and muamalah) which is based on a solid foundation of aqeedah. Like a building, character or morals are the perfection of the building after the foundation and the building are strong. It is impossible for a character or noble character to manifest in someone if he does not have the right aqeedah and sharia. A Muslim who has true aqeedah or faith will surely manifest in attitudes and behaviors in daily life based on his faith. For example, people who have good and true faith in Allah SWT, he will always obey and carry out all His commands and stay away from all His prohibitions. He will always do good and stay away from things that are prohibited (bad). Faith is not only to Allah SWT, but also to angels, books, Apostles and so on will make their attitudes and behavior directed and controlled, so that they will manifest noble character or character. The same thing happened in the case of sharia implementation. All Islamic sharia provisions lead to the realization of noble character or character
