Abstract

Peningkatan aktivitas mengajar secara daring terlebih saat masa darurat penyebaran virus COVID – 19 melanda, membuat tenaga pendidik utamanya seorang guru sangat terbantu apabila memiliki kecakapan dalam penggunaan teknologi, untuk menjangkau para murid yang melaksanakan pembelajaran dari rumah. Oleh karena itu, perlu diadakannya peningkatan komptenesi guru dalam bidang digital education sesuai dengan era saat ini. Berdasarkan kendala yang dimiliki mitra yaitu kurangnya keterampilan SDM (guru) dalam mengolah media pembelajaran berbasis digital untuk meningkatkan minat belajar siswa, agar siswa dapat memahami pembelajaran meskipun menggunakan sistem belajar online utamanya di SMA Negeri 1 Bahodopi. Sesuai pelaksanaannya, Kegiatan peningkatan kompetensi guru di SMA Negeri 1 Bahadopi telah terlaksana dengan baik, namun ada beberapa kendala yang diharapi selama kegiatan ini berlangsung yaitu ketidaksesuaian waktu pelaksanaan, materi yang diberikan belum terperinci, serta keterbatasan perangkat pendukung pembuatan video. Sehingga, para peserta yang terdiri dari guru sekolah dan tim pelaksana menggunakan berbagai peralatan yang ada. Demi mendukung kegiatan tersebut berlangsung dengan baik.

Abstract

The purpose of this study is to determine the effect of power on marking quality, namely groove geometry and marking visibility and corrosion rate on AISI 304 stainless steel fiber laser marking material in corrosive seawater media. This is important because based on the results of the analysis report from the information department, the results of fork and spoon products experience corrosion, especially in the area of laser marking results. In this study, the surface of AISI 304 stainless steel material is given laser marking treatment with power variations, namely 20 and 60 W. The results of SEM testing will be carried out to obtain data on the results of groove geometry and visibility of the marking results. Furthermore, the AISI 304 stainless steel material from the marking is immersed in corrosive sea water media for a span of 60, 90 and 120 days to measure the corrosion rate that occurs. As a result, the AISI 304 stainless steel marking material is also subjected to SEM observation to determine the type of corrosion and surface morphology of the laser marking results due to the influence of corrosion that occurs. It is expected that the results of this study will be able to provide recommendations for work process parameters in laser marking that can be applied to spoon and fork products as optimal parameters for improving the quality of better marking results.

Abstract

Used lubricating oil contains contaminants that can pollute the environment if not managed properly. One of the contaminants contained in it is heavy metals. Adsorption using adsorbent materials such as bentonite has become one of the commonly used methods for removing contaminants in used lubricating oil. Bentonite is a clay that is good for use as an adsorbent for heavy metals because it has large enough particles that are good for absorbing them. However, the effectiveness of bentonite adsorption can be influenced by the mass of bentonite used in the process. This research aims to determine the effectiveness of the influence of bentonite mass on reducing Pb metal in lubricating oil using HCl-activated bentonite. The research results show that increasing the mass addition of bentonite can increase the effectiveness of adsorption and the removal efficiency of Pb metal in used lubricating oil. This is characterized by a decrease in Pb metal content in used lubricating oil before and after the adsorption process, namely in sample A with the addition of 2 grams. The Pb metal content in used lubricating oil is 0.2471 ppm, 4 grams is 0.2000 ppm, 6 grams is 0.142 ppm, at 8 it was 0.0895 ppm, and at 10 grams it was 0.0316 ppm. In sample B, with the addition of 2 grams, the metal content of Pb in the used lubricating oil was 0.3000 ppm, 4 grams was 0.2474 ppm, 6 grams was 0.2053 ppm, 8 grams was 0.1474 ppm, and 10 grams was 0.0684 ppm.

Abstract

Penelitian ini mengevaluasi pengaruh konsentrasi asam sitrat terhadap persen recovery nikel pada proses leaching bijih nikel laterit (limonit) dengan kondisi operasi tetap. Variasi konsentrasi asam sitrat yang diuji adalah 0,5 M; 1,0 M; dan 2,0 M, sedangkan parameter operasi dijaga konstan pada suhu 80 °C, waktu leaching 60 menit, dan rasio padat-cair 1:5. Preparasi bijih dilakukan melalui pengeringan, penghancuran, dan pengayakan pada ukuran 100, 150, dan 200 mesh. Kandungan nikel awal bijih dianalisis dengan XRF sebesar 1,67%. Persen recovery dihitung berdasarkan neraca massa-konsentrasi antara umpan dan residu. Hasil menunjukkan bahwa peningkatan konsentrasi asam sitrat meningkatkan persen recovery pada seluruh ukuran partikel. Rentang persen recovery yang diperoleh adalah 74,45–78,29%, dengan nilai tertinggi pada konsentrasi 2,0 M dan ukuran partikel 200 mesh (78,29%), serta nilai terendah pada konsentrasi 0,5 M dan ukuran 100 mesh (74,45%).
