Abstract

Research on making liquid smoke from teak and pine sawdust by pyrolysis which will be used as a natural preservative. Pine and teak sawdust carried out a pyrolysis process for 4 hours at a temperature of 400 oC using a pyrolysis reactor with a maximum capacity of 2 kg. The ratio of teak wood powder raw material: pine wood used 1:0; 0:1 and 1:1. Then purified by distillation with a distillation temperature of 100, 101-125, 126-150 oC. Liquid smoke application is used on tofu food with observation time of 2, 3, 4, 5 and 6 days. The quality of the liquid smoke produced is a mixture of sawdust and teak (1:1) at a distillation temperature of 126-150 oC, namely pH 3.1, density 1.028 g/mL and the clearest color and able to preserve food for up to 4 days.

Abstract

This gas source that comes from the bowels of the earth contains many impurities and heavy hydrocarbons, both of which must be separated or even eliminated. To purify the treated gas to prevent damage to process equipment or pipe clogging. The removal process includes H2S removal, CO2 removal, oily water removal, mercury removal, and water content removal in natural gas. This study aims to determine the effect of flow rate and ambient temperature differences on the performance of the wellstream cooler and the level of efficiency of the heat transfer process in the wellstream cooler. Observations will be focused on the offshore platform wellstream cooler cooling system at PT. PHE NSO. Based on observational data, the results obtained using the Hysys method by entering the required data completely, Hysys will automatically perform calculations according to what is required and the calculation results will be plotted in graphical form. Heat transfer efficiency based on Hysys application calculations all show results of 99%. Thus it can be seen the effect of changes in flow rate and ambient temperature on the heat transfer process. The greater the flow rate, the greater the heat transfer that occurs and the higher the ambient temperature, the smaller the heat transfer occurs, so that the lower the ambient temperature, the more effective the heat transfer occurs.

Abstract

Absorption was a separation process between gas fluids using liquid fluid media. The glycol contactor aims to separate the water content contained in the gas using tri-ethylene glycol media with process conditions at a pressure of 795-810 psi and a temperature of 85-110 oF. The contact process between fluids is assisted by the Intalox Saddle type packing which aims to maximize the contact process between fluids and it is hoped that the absorption process that occurs can be maximized. Tri-ethylene glycol which has absorbed the water content in the gas is regenerated in the glycol burner. This analysis used 4 packing variables (Raschig Rings, Pall Rings Plastic, Berl Saddles Ceramic, and Intalox Saddles Ceramic), 5 flow rate variables (1600, 1800, 2000, 2200, and 2400 BPD) and this analysis use the Hysys simulation program. Based on these variables, the absorption efficiency analysis results are obtained in the range of 93-94%, and the flooding percentage is 21-36%. It can be concluded that the type of packing is very influential on the percentage of flooding. Pall Ring Plastic was the type of packing with the lowest flooding percentage. According to research, lower flow rates increase the efficiency of H2O absorption.

Abstract

Balai pengajian Babul Muta’allimin merupakan salah satu balai pendidikan agama yang terdapat di Desa Blang Awe, Kecamatan Syamtalira Bayu, Kabupaten Aceh Utara. Sekalipun sudah berkiprah lebih dari 20 tahun, balai pengajian Babul Muta’allimin sampai saat ini sama sekali tidak memiliki sarana wudhu yang memadai untuk santri. Padahal, sarana tersebut meruapakan salah satu kebutuhan utama bagi para santri yang belajar AlQurán dan sholat di balai pengajian tersebut. Kegiatan pengabdian kepada masyarakat ini bertujuan mengembangkan suatu sistem Penyedia Air Wudhu (SPAW) berbasis sumber daya lokal, yang dapat dikelola dan dirawat secara mandiri oleh mitra. Kegiatan PkM dilaksanakan dalam 3 (tiga) tahapan, meliputi: (1) Pengembangan Sistem Penyedia Air Wudhu (SPAW) untuk mitra; (2) Pembekalan pengetahuan dasar tentang operasional dan perawatan paket teknologi yang dikembangkan, serta; (3) Evaluasi keberhasilan kegiatan, menggunakan kuisioner. Setelah kegiatan PkM diselesaikan, suatu Sistem Penyedia Air Wudhu’ (SPAW) berbasis sumber daya lokal sudah tersedia untuk mitra kegiatan. Sistem tersebut mampu menyediakan air wudhu’dengan kapasitas 2,14 liter/menit pada 7 titik akses terintegrasi, dengan kualitas air yang memenuhi baku mutu air untuk keperluan hygiene sanitasi menurut Kepmenkes RI No. 32 tahun 2017. Hasil evaluasi kepuasan mitra menunjukkan bahwa mitra memberi apresiasi positif terhadap kegiatan PkM yang telah dilaksanakan.
