Abstract

Analisis Penggunaan Bahan Bakar High Speed Diesel (HSD) dan Marine Fuel Oil (MFO) Terhadap Parameter Titik Utama Siklus Kerja dan Performa Mesin Diesel Mitsubishi Man Type 18V52/55A. Penelitian ini dilaksanakan di PT. PLN (Persero) Sulselrabar yang bertujuan untuk mengetahui pengaruh penggunaan bahan bakar jenis HSD dan MFO terhadap parameter titik utama siklus kerja dan performa mesin diesel Mitsubishi MAN type 18V52/55A. Metode dokumentasi digunakan untuk memperoleh data sekunder berupa spesifikasi mesin dan jam operasi mesin selama bulan September dan oktober. Hasil pengolahan data diperoleh dengan menggunakan program Microsoft Office Excel. Pada bagian pertama disajikan data hasil perhitungan parameter termodinamika di titik-titik utama siklus kerja mesin. Pada bagian kedua disajikan data hasil perhitungan parameter kinerja mesin. Hasil pengolahan data perhitungan parameter termodinamika di titik-titik utama siklus kerja mesin diesel saat menggunakan bahan bakar HSD dan MFO menunjukan bahwa, setiap peningkatan 1 oK suhu dan atau 1 kg/cm2 tekanan pada tiap satu titik utama siklus akan diikuti dengan peningkatan pada titik lainnya demikian pula sebaliknya. Hasil perhitungan parameter kinerja mesin diesel berbahan bakar HSD dan MFO menunjukan, perolehan Daya Indikator (Ni) dan Daya Efektif (Ne) bahan bakar MFO lebih tinggi yaitu 3244,7064 PS dan 2758,0004 PS dibandingkan dengan HSD yang memiliki Daya Indikator (Ni) 3078,079 PS dan Daya Efektif (Ne) 2616,367 PS. Hal ini menandakan bahwa daya mesin yang dihasilkan mesin saat menggunakan bahan bakar MFO lebih tinggi dibandingkan saat menggunakan HSD. Terlihat pula bahwa penggunaan bahan bakar lebih besar saat mesin beroperasi menggunakan bahan bakar HSD disbanding saat menggunakan MFO. Dengan demikian, performa mesin saat menggunakan bahan bakar MFO lebih baik daripada saat menggunakan bahan bakar HSD.

Abstract

This study aims to determine the ratio of chlorine levels in rice before and after it is cooked using the iodometric method. This research was conducted on June 12 - July 7 2023 at the ITKeSMU Sidrap Chemistry Laboratory. The type of research conducted is laboratory experimental research to investigate certain symptoms or substances through tests and tests with quantitative examination using the iodometric method. Sampling in this study was carried out randomly by taking rice that has a intact shape, is not easily broken, rice has just been milled. The method test and the calculation of the average chlorine content in rice samples before and after cooking. The results showed that there was a large difference between the chlorine content in rice before cooking, which was an average of 127,16% and after cooking, which was an average pf 48,323%

Abstract

Kurangnya deteksi dini mengenali tanda-tanda bahaya kehamilan dan faktor-faktor resiko pada kehamilan dapat mengakibatkan kurangnya antisipasi yang cepat pada saat kehamilan sampai proses persalinan sehingga sangat beresiko besar terjadinya kematian ibu. Untuk itu dengan adanya penyuluhan mengenai tanda-tanda bahaya kehamilan diharapkan dapat meningkatkan pengetahuan ibu tentang tanda-tanda bahaya kehamilan. Penyuluhan tanda-tanda bahaya kehamilan ini dilaksanakan di praktek mandiri bidan (PMB) Winarni, SST Kota Pekanbaru, yang dilaksanakan pada tanggal 10 Juni 2022. Hasil dari penyuluhan ini didapatkan meningkatnya pengetahuan ibu hamil tentang tanda-tanda bahaya pada kehamilan
