Abstract

Penelitian tentang teknologi penangkapan lobster dengan modifikasi warna krendet dan kedalaman daerah penangkapan diperlukan agar mendapatkan hasil tangkapan lebih banyak. Tujuannya untuk mengetahui pengaruh perbedaan warna krendet (merah dan transparan) dan kedalaman daerah penangkapan terhadap hasil tangkapan. Penelitian ini dilakukan pada bulan Desember 2013 di Pantai Waru, Paranggupito, Wonogiri menggunakan metode eksperimental fishing. Hasil penelitian menunjukan bahwa terdapat pengaruh perbedaan warna krendet dan kedalaman daerah penangkapan, hal ini dilihat dari hasil tangkapan pada krendet merah di kedalaman 8-10 m sebesar 1930 gram dan kedalaman 3-5 m sebesar 4190 gram, krendet transparan kedalaman 8-10 m 1530 gram dan kedalaman 3-5 m sebesar 2350 gram. Hasil analisis dengan taraf uji 0,05 pada krendet transparan nilai sign = 0,087 menunjukan bahwa H0 diterima dan merah nilai sign = 0,002 H0 ditolak, dan sign kedalaman daerah penangkpan 8-10 m = 0,405 H0 diterima dan kedalaman daerah penangkpan 3-5 m = 0,007 sehingga H0 ditolak. Berdasarkan hasil tersebut dapat disimpulkan bahwa krendet merah dengan kedalaman daerah penangkapan 3-5 m lebih banyak mendapatkan hasil tangkapan. Tidak ada interaksi dari kedua perlakuaan tersebut. The Research on the technology fishing lobster with modify the krendet’s colour and the fishing ground depth in order to get more catching result. The aims to determine the influence of difference the krendet’s colour (red and transparent) and the fishing ground depth to catch lobster. The research was done in December 2013 at Waru beach, Wonogiri using experimental fishing method. The result showed that there was influence in the difference of the krendet’s colour and the fishing ground depth, it was proved by the catching result of the red krendet at a depth of 8-10m  was 1930 grams and at a depth of 3-5m  was 4190 grams, where as the transparent krendet­­ at a depth of 8-10m was 1530 grams and at a depth of 3-5m  was 2350 grams. The analysis  result with adequate test 0,05 on the transparent with sign = 0,087 showed that H­0­ was accepted whether the H0 of the red one with sign = 0,002 was declined, and the sign in the fishing ground depth of 8-10 m was 0,405 so the H0 was accepted where as the sign in the fishing ground depth  of 3-5 m was 0,007 so the H0 was declined. Based on the result, it can be concluded that the red krendet on the fishing ground depth in 3-5 m had more catching result. There was no interaction on the mentioned treatments.

Abstract

Rice husk is an agricultural waste which contains 50% cellulose, 25%-30% lignin and 15%-20% silica. It can be used as raw material of bio-oil. Bio-oil is liquid which produced by pyrolysis process. Bio-oil can be produced from the rice husk at 773 and 873 K. The main component of Bio-oil from rice husk pyrolysis at 773 and 873 K is phenolic compounds about 47.98% and 62.65%, respectively. It causes corrosive, low heating value, high acidity, high viscosity and unstable that causing an engine damage. The presence of phenolic compound decreases the quality of bio-oil. Therefore, it needs a process such as liquid-liquid extraction to reduce the phenolic compound using 80% methanol and 80% chloroform as a solvent. The extract and raffinate phase were analyzed using UV-Vis spectrophotometer. The aim of this research determine the effect of temperature pyrolysis for the characterization of bio-oil, the stirring speed and the temperature of the extraction for the distribution coefficient and the yield of phenolic compound. The results showed that the characterization of bio-oil produced from rice husk pyrolysis at 773 and 873 K are densities 1,040 and 1,042 Kg/m3; viscosities 9.3488 and 9.5007 cSt; acid numbers 46.75 and 52.45 mg KOH/g; pH 2.5 and 3; flash points 426 and 423 K and heating values 3.229 and 3.339 MJ/kg, respectively. The highest distribution coefficient and yield were obtained at 323 K and a stirring speed of 250 rpm. The distribution coefficient of bio-oil produced by pyrolysis at 773 and 873 K is 1.504, and 1.528, respectively. The yields of bio-oil produced by pyrolysis at 773 and 873 K are 58.885%, and 48.429%, respectively.

Abstract

This study tends to understand about the implementation, payment, and reporting of Value-added Tax in Cooperative “X”. It is also aimed to explore the accounting treatment and its effect on the financial statement. To reach this goal, a researcher use qualitative method. Data is taken by Case Study approach with do some documentation, observation, interview, and literature study from the research object. The result conclude that the company has properly fulfilled the obligation of Value-added Tax and appropriately reported it based on Value-added Tax Act. However, Cooperative “X” is still has not yet acknowledged Value-added Tax of consignment goods, doing some improper conduct at making entries, classifying tax obligation account, and the absence of input and output tax. These conduct resulted in financial statement especially Balance Sheet statement. Keywords : VAT Implementation, VAT Payment, VAT Reporting, VAT Accounting, Financial Statement
