Abstract

Penelitian adsorpsi dari bahan alam telah banyak dilakukan dari berbagai bahan baku seperti ampas tebu, ampas kopi, bentonit dan lainnya. Namun persyaratan mekanis dan pengolahan dari berbagai aplikasi belum dapat dipenuhi. Pada studi ini telah  dilakukan pengolahan adsorben berbahan kaolin menggunakan teknologi ultasonik untuk meningkatkan daya serapnya untuk mereduksi logam dalam air dengan cara memodifikasi kaolin dengan surfaktan anionik dan diiradiasi ultraonik. Tujuannya adalah  mengoptimalisasi  penyerapan  logam  yang lebih sepesifik dalam menyerap logam Fe dan Mg dalam air menggunakan  kaolin  yang  telah  dimodifikasi.  Kaolin dihaluskan sampai dengan 100 mesh dan dicampurkan dengan surfaktan anioinik sebanyak  45%, dari berat total adsorben  yaitu  200  gram.  Proses adsorpsi dilakukan menggunakan kaolin modifikasi surfaktan dan tanpa modifikasi surfaktan dengan memvariasikan waktu  iradiasi  yaitu  5, 10, 15, 30,  50  dan  80  menit  pada suhu 55 °C. Konsentrasi logam diukur menggunakan Atomic Absortion Spectrofotometers (AAS) serta dilakukan perhitungan kinetika adsorbsi. Hasil penelitian menunjukkan bahwa efisiensi penyisihan tertinggi terjadi pada kaolin yang dimodifikasi dengan surfaktan anionik. Hasil yang paling signifikan yaitu untuk Fe efisiensi penyisihannya mencapai 72,81 % pada waktu iradiasi 5 menit, sedangkan untuk Mg efisiensi penyisihannya mencapai 65,1% pada waktu iradiasi 5 menit. Kata kunci: Adsorpsi, Adsorben, Kaolin, Ultrasonik, Surfaktan

Abstract

Kaolin is one of the natural adsorbent materials. The adsorption ability of kaolin is still low and need to be modified with organic compounds such as surfactants. This research aimed to optimize the lead adsorption in a waste water using modified kaolin. This study modified kaolin adsorben with cationic surfactants which have activated on temperature 300oC during 3 hours in a furnace. The comparison of kaolin and surfactant were 1:0, 1:2, 1:3 and 2:1, respectively while adsorption time were 30, 60 and 90 minute. Lead was used as the artificial waste at a concentration of 100 ppm. The waste from municipal reservoir water storage of Lhokseumawe was used as a benchmark and application. The sample was analyzed by using AAS and characterized by FTIR. The modified adsorben kaolin-surfactan 1:2 gained the highest reduction of efficiency 78% while the lead ion of municipal waste decreased from 4.65 ppm into 2.67 ppm.

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.

Abstract

This research was conducted to separate used oil using a separator with activated carbon separation media and used cardboard. The treatment was carried out with time variations (minutes) 5, 10, 15, 20, and 25. With variations in the composition of used oil 2%, 4%, 6%, 8%, and 10%. Oil collection as a sample was carried out at a motorcycle workshop in Gampong Java, Banda Sakti District, Lhokseumawe City. The results of the study were tested for characteristics, pH, total dissolved solid (TDS), turbidity, and chemical oxygen demand (COD) in accordance with quality standards. These results show that pH, turbidity and TDS decrease with the longer the time left for sampling the separation results. Meanwhile, TDS and COD there are some samples that are still slightly below standard. With the influence of the residence time of sampling of sampling separation results, the results of the characteristic test are getting better and more stable. The results of this study show that used oil separation media using activated carbon and used cardboard can be used as a prevention of environmental pollution.

Abstract

This study aims to utilize kaolin as a membrane to reduce CO emissions in vehicles. The study was designed with constant variables including 10% PVA, 10% TiO2 catalyst, 8% starch adhesive, and 130 ml of distilled water, resulting in a total mixture weight of 140 grams. The membrane dimensions were 70 mm in length and 50 mm in diameter, with 19 holes of 3 mm each. Independent variables included kaolin carbon ratios (6:1, 5:1, 4:1, 3:2, 1:1) % of total mixture weight, engine rotation (1000, 2000, and 3000) rpm, and sintering temperatures (800°C, 900°C).The CO absorber is a component of the exhaust system designed to reduce carbon monoxide content in exhaust gases from internal combustion engines. CO absorbers typically consist of noble metal catalyst plates (such as platinum, palladium, and rhodium) embedded on ceramic or metal substrates. When exhaust gases pass through the CO absorber, catalytic reactions occur on the catalyst surface, converting carbon monoxide into carbon dioxide (CO2), which is safer for the environment. The study results showed that membranes with a composition of 65.8 g kaolin and 35 g activated carbon absorbed 84.64% of CO exhaust gases, achieving a final CO concentration of 0.80% at 1000 rpm. At 2000 and 3000 rpm, membranes with a composition of 72.8 g kaolin and 28 g activated carbon absorbed 90.45% and 92.31% of CO exhaust gases, with final CO concentrations of 0.57% and 0.54%, respectively. These results comply with the Ministerial Regulation No. 05 of 2006, which sets the CO emission threshold at 1.5% for the year 2007.
