Abstract

Dalam tulisan ini disajikan hal-hal yang menyangkut teori dan hasil penelitian mengenai pengaruh mutu bahan bakar solar terhadap rendemen pembakaran dan unjuk kerja (performance) mesin diesel. Dijelaskan juga bahwa mutu solar yang tinggi dapat mempersingkat waktu kelambatan penyalaan (ignition delay) sehingga dapat meningkatkan rendemen pembakaran dan unjuk kerja mesin.

Abstract

Besar kecil randemen termis tergantung pada perbandingan komresi suatu mesin, sedangkan randemen termis langsung mempengaruhi terhadap unjuk kerja, jumlah pemakian bahan bakar dan komposisi gas buang mesin. Akibat terjadinya peningkatan teknologi mesin yang bertujuan untuk meninggalkan efisiensi mesin, maka kualitas bahan bakar harus sesuai dengan desain tersebut. perunahan desain mesin antara lain menyangkut bentuk ruang bakar dan perbandingan kompresi, sehingga tingkat angka oktan bensin harus sesuai dengan berubahnya desain mesin.

Abstract

Dalam rangka usaha meningkatkan mutu bebas (Ignitas Quality) bensin produksi Cepu, maka dilaksanakan penelitian dengan penambahan antiknock additive (TEL dan TML) pada bensin Cepu. Sebelum melakukan pengujian terlebih dahulu menyediakan contoh-contoh yang terdiri dari bensin murni produksi Cepu, TEL dan TML. Kemudian melaksanakan pengujian laboratorium yaitu angka oktan bensin murni Cepu ditambah dengan beberapa ml TEL dan TML dan kemudian mengamati terhadap tingkat Oktan yang dicapai akibat penambahan masing-masing antiknock additive tersebut.

Abstract

Dalam rangka peningkatan jumlah pengilangan bahan bakar minyak di Indonesia untuk memenuhi kebutuhan dalam negeri sangatlah dibutuhkan laboratorium mesin CFR yang selalu standard dan persisi, karena ketelitian mesin CFR sangat mempengaruhi biaya produksi bahan bakar bensin. Disamping itu juga dibutuhkan untuk kegiatan penelitian kwalitas BBM serta adanya usaha-usaha untuk mengganti bensin dengan campuran Methanol atau Alkohol.

Abstract

During the 2nd Workshup on the ASCOPE Laboratory Test Correlation Programme which was, held in Kuala Lumpur 17 - 18 August 1981, the following consensus was reached among participating laboratories : • The frequency of the correlation test programme should be increased to twice a year. • Testing should be carried out at the same day and time specified by the Programme coordinator. • Testing should be carried out according to the same procedure (bracketing Method). Member countries taking part in this correlation programme are Indonesia as coordinator with seven laboratories participating, Malaysia with one laboratory, Thailand and the Philip- pines with two laboratories each. The coordinator in this correlation programme is respon- sible in preparing the correlation samples and sending them by air to each participating laboratory. The first part of this programme (3rd Correlation Programme) was started by sending samples in January 1982 and the second part (4th Correlation Programme) was starting by sending samples in March 1982. It will appear in the next publication. After being tested by the participating laboratories, the test result are to be sent to the coordinator for the determination of the standard deviation and other statistical data. Based on these results, conclusions can be drawn about the deviation of laboratory test results and about outliers to be rejected. For better analysis of the results, for each of the samples for correlation it is also required to report physical and chemical tests such as specific gravity, R.V.P., distillation and lead (TEL) content in the receiving laboratories. This is necessary in order to take into account any possible changes in the sample properties which might have occured during transporta- tion and storage. Also to be observed are ambient and engine operating conditions during the correlation tests. The results of this analysis can then be used as a base for deviations the occurence of outliers and recommendation of remedial steps to be taken. d The method used for testing the samples is the bracketing method, while for rounding the value of the member found during the tests the ASA rules for rounding are used. SADIM The Grubb's rejection criteria with the use of "T" factors is used in evaluating the possible outliers. • Presented by the Indonesian Technical Committee to the Workshop on ASCOPE Laboratory held in Bangkok, Thailand, 9- 11 October 1982.
