Mesoporous silica (MS) supported by nickel was synthesized from Parangtritis beach sand and assessed for its activity and selectivity as catalysts in hydrocracking waste cooking oil into biofuel. The synthesis of MS was done by the sol-gel method. Ni/MS catalysts using Ni weight variations of 1, 5, and 10 wt.% were denoted as Ni/MS1, Ni/MS5, and Ni/MS10 and were compared to standard mesoporous silica (Ni/SBA-15). The catalysts were characterized using FTIR, XRD analysis, N2 gas sorption analysis, SEM-EDX, and TEM. Catalyst Ni/MS1, Ni/MS5, Ni/MS10, and Ni/SBA-15 have specific surface areas of 130.5, 195.9, 203.9, and 381.2 m2/g and the average pores of 12.30, 9.80, 11.12, and 8.70 nm, respectively. The hydrocracking was run four times to evaluate the catalyst reusability. The hydrocracking WCO has 95.8, 82.4, and 85.2%, respectively. While Liquid fractions produced were 38.8, 43.2, and 50.2 wt.%, each of which contains gasoline of 37.09, 39.76, and 44.27 wt.%, Ni/MS10 has the highest liquid products of 50.2 wt.% and was selective to gasoline fractions up to 44.27%. Therefore, the catalyst synthesized from Parangtritis beach sand is selective for gasoline-fraction hydrocarbon and has hydrocracking activity up to 4 runnings.

Decision-making in the organization always relates to the description of the results of the decisions taken. Therefore, every organization needs a management information system to assist in making various kinds of decisions needed. The purpose of this study was to determine the influence and effectiveness of management information systems on decision-making in the field of archives. The method used in this study is the explanatory survey method. Data collection techniques were carried out using questionnaires and product correlation moments. Data analysis was performed using simple regression analysis and hypothesis testing. The subjects of this study were 120 administrative employees in the city of Bandung. To support the analysis, this study also carried out a bibliometric analysis to determine trends in research development from information management systems to decision-making. Based on the findings, the quality of the management information system used is in the high category, as well as the effectiveness of decision-making is in the high category. Based on the results of hypothesis testing and significance, it can be interpreted that the management information system has a positive and significant effect on decision-making in the field of administration.

Nanopartikel Fe3O4 merupakan jenis nanopartikel yang berperan penting dalam kehidupan industri. Namun, masih jarang ditemukan proses sintesis Fe3O4 menggunakan sistem heat exchanger pada skala industri sehingga penelitian ini dilakukan untuk merancang heat exchanger jenis shell and tube dalam proses produksi nanopartikel Fe3O4 pada skala industri. Metode yang digunakan pada penelitian ini yaitu perhitungan matematis menggunakan lebih dari 20 persamaan yang diturunkan berdasarkan pengaruh dimensi dan spesifikasi fluida dan kemudian data yang diperoleh diolah dengan menggunakan aplikasi Microsoft Excel. Rancangan alat HE memiliki spesifikasi panjang tube 4,572 m, diameter tube 0,0254 m, dan ketebalannya 0,0018 m. Lalu data diolah menggunakan software pengolah data Microsoft Excel. Hasilnya menunjukkan bahwa rancagan heat exchanger jenis shell and tube ini memiliki nilai efektivitas 93% dengan faktor kemurnian 0,01 jam.ft2.oF/Btu. Dari penelitian ini diketahui jenis HE shell and tube yang dirancang belum sesuai dengan standar yang telah ditetapkan oleh industri.
