Petroleum products. Determination of knock characteristics of motor fuels. Research method

This paper presents a method of sorption using peat for elimination of emergency spills of crude oil and petroleum products and the possibility of energy use of oil-saturated peat. The results of assessment of the sorbent capacity of peat are presented, with waste motor oil and diesel fuel chosen as petroleum products. Natural peat has been found to possess sorption properties in relation to petroleum products. The sorbent capacity of peat can be observed from the first minutes of contact with motor oil and diesel fuel, and significantly depends on their viscosity. For the evaluation of thermal properties of peat saturated with petroleum products, experimental studies have been conducted on determination of moisture and ash content of as-fired fuel. It is shown that adsorbed oil increases the moisture and ash content of peat in comparison with the initial sample. Therefore, when intended for energy use, peat saturated with petroleum products is to be subjected to additional drying. Simulation of net calorific value has been performed based on the calorific values of peat and petroleum products with different ratios of petroleum product content in peat and for a saturated peat sample. The obtained results are compared with those of experiments conducted in a calorimetric bomb and recalculated for net calorific value. A satisfactory discrepancy is obtained, which amounts to about 12%. Options have been considered providing for combustion of saturated peat as fuel (burnt per se and combined with a solid fuel) and processing it to produce liquid, gaseous and solid fuels. Peat can be used to solve environmental problems of elimination of emergency spills of crude oil and petroleum products and as an additional resource in solving the problem of finding affordable energy.

Submission of Certificate of Origin (e-Form D) is conducted through a three-layer system named ASW Gateway, LNSW, and CEISA has raised issues related to the period/time of receipt of e-Form D given by customs authorities for the purposes of charging preferential tariffs in the ATIGA scheme. This article aims to analyze the legal certainty in submitting e-Form D to the customs authorities in the importing country, in this case, the Directorate General of Customs and Excise for the purpose of charging preferential tariffs, so that it can be in line with the presentation principle based on the ATIGA OCP and Indonesian domestic legal provisions. The research method used is a normative juridical approach with descriptive analysis and normative qualitative to draw conclusions. Based on the research, it was concluded that with regard to the submission of e-Form D, Customs and Excise Officials must have confidence based on factual evidence to determine whether the principle of submission of e-Form D has been accomplished or refused when an interruption in the ASW Gateway, LNSW or CEISA happened so the Customs Officer and Excise can determine tariffs based on OCP as well as domestic law in force in Indonesia.Keywords: ATIGA, Customs Authority, Directorate General of Customs and Excise, e-Form D, Tariffs Preference.ABSTRAK: Penyerahan SKA e-Form D dilakukan melalui tiga layer system yakni ASW Gateway, LNSW, dan CEISA memunculkan permasalahan terkait dengan jangka waktu/saat diterimanya e-Form D oleh otoritas kepabeanan untuk kepentingan pengenaan tarif preferensi dalam skema ATIGA. Penelitian bertujuan menganalisis kepastian hukum dalam penyerahan e-Form D ke otoritas kepabeanan di negara importir, dalam hal ini Direktorat Jenderal Bea dan Cukai untuk kepentingan pengenaan tarif preferensi, sehingga dapat sejalan dengan prinsip presentasi berdasarkan OCP ATIGA dan ketentuan hukum domestik Indonesia. Metode penelitian dilakukan dengan pendekatan yuridis normatif secara deskriptif analisis dan penarikan kesimpulan secara normatif kualitatif. Berdasarkan penelitian, disimpulkan bahwa berkenaan dengan penyerahan e-Form D, Pejabat Bea dan Cukai harus memiliki keyakinan berdasarkan bukti faktual untuk menentukan apakah prinsip penyerahan e-Form D sudah dipenuhi/tidak ketika terjadi gangguan pada ASW Gateway, LNSW atau CEISA sehingga Pejabat Bea dan Cukai dapat menentukan tarif berdasarkan OCP maupun hukum domestik yang berlaku di Indonesia. Kata Kunci: ATIGA, Direktorat Jenderal Bea dan Cukai, e-Form D, Otoritas Kepabeanan, Tarif Preferensi.

Revenue Production

The purpose of this researchment is to ascertain how wide the farming of species Saccharun Edule Hasskarl (terubuk) in sub district Tosa, district of East Tidore of Tidore Island through the indicator of the value revenue, production and selling prices so that the farmers will achieve The Break Event Point (BEP). The research method was used a quantitative method with the number of samples of 30 people. The determination of the sample method is using the census method or involving all members of the population into a sample of researchment. The secondary data collection was done by using library literature in the form of document review and relevant references to research object while primary data collection was done by using questionnaire. The data is using equation R /C Ratio, BEP Revenue, BEP Price, and BEP Production. Therefore from the results of the researchment it can be explained that the two of the thirty farmers come through the break event point, while the other twenty-eight farmers declared having a business that worth to be develop or experiencing profit, because the R/C ratio is above 1.0 with average profit reach Rp. 989.000, - per production / farmer.
