Abstract

Perkembangan dunia otomotif di Indonesia semakin pesat, sehingga emisi dari sektor transportasi sangat tinggi. Salah satu solusi untuk mengurangi emisi adalah produksi listrik dari sumber energi terbarukan seperti air, angin, matahari, dan panas bumi. Hal ini mendorong perkembangan kendaraan listrik semakin meningkat pesat dari sektor transportasi. Pemerintah juga mendukung pertumbuhan industri baterai dan kendaraan listrik di Indonesia. Upaya untuk mendukung program pemerintah tersebut adalah menyiapkan sumber daya manusia (SDM) yang kompeten di bidang kendaraan listrik melalui kegiatan pelatihan komponen kendaraan listrik, khususnya battery pack. Sekolah Menengah Kejuruan (SMK) harus cepat beradaptasi dalam menghadapi perkembangan teknologi tersebut, sehingga SMK dengan Program Keahlian Teknik Bisnis Sepeda Motor dan Teknik Kendaraan Ringan Otomotif hendaknya mencetak lulusan yang kompeten dalam pembuatan battery pack yang diaplikasikan pada kendaraan listrik. Oleh karena itu, pengabdian masyarakat dilakukan di SMK Roudlotul Huda Magetan mengenai pelatihan pembuatan battery pack berbasis baterai lithium ion. Pada awal kegiatan, siswa dibekali materi mengenai baterai lithium ion dan battery pack. Selanjutnya, siswa melakukan praktik untuk perangkaian baterai (welding) dan pemasangan casing. Berdasarkan hasil pre-test dan post-test, siswa mengalami peningkatan pemahaman mengenai battery pack. The development of the automotive sector in Indonesia is increasing rapidly, so emissions from the transportation sector are very high. One solution to reduce emissions is the production of electricity from renewable energy sources such as air, wind, sun, and geothermal. This encourages the development of electric vehicles rapidly in the transportation sector. The government also supports the growth of the battery and electric vehicle industry in Indonesia. Efforts to support this government program are by preparing competent human resources (HR) in the field of electric vehicles through training activities on electric vehicle components, especially battery packs. Vocational High Schools (SMK) must quickly adapt to these technological developments, so Vocational Schools with Teknik Bisnis Sepeda Motor and Teknik Kendaraan Ringan Otomotif Skills Programs should produce graduates who are competent in making battery packs that are applied to electric vehicles. Therefore, community service was carried out at Roudlotul Huda Magetan Vocational School regarding training in making battery packs from lithium-ion batteries. At the start of the activity, students were provided with material regarding lithium-ion batteries and battery packs. Next, students practice battery assembly (welding) and casing installation. Based on the pre-test and post-test results, students experienced an increased understanding of battery packs.

Abstract

The synthesis of CoMo/USY catalysts has been widely carried out. However, the bond strength between metal and USY is still a problem. Therefore, this research has synthesised the catalyst with the chelating agent ethylenediaminetetraacetate (EDTA). Apart from that, the effect of pH on the characteristics of the catalyst is also reviewed. This research aims to analyse the effect of preparation pH on catalyst characteristics. In the preparation process, the pH of the solution is set at values of 2, 7, and 8. Catalyst activation includes a calcination process and reduction. The catalyst characterisation uses XRD, GSA, and FTIR instruments to determine phase composition, specific surface area, and functional groups. The result showed that pH preparation significantly influenced the metal loading on the catalyst and reached a maximum at pH 8. The surface area is not directly related to the pH of the preparation but has the opposite property depending on the amount of metal added. Meanwhile, it was found that the CoO and MoO3 phases were achieved on the catalyst by all pH preparations. On the other hand, the CoMo alloys are present on the catalyst at pH 7 and 8, while the Co and Mo elements are visible at pH 2. The difference in pH during the synthesis process impacts the shift in the absorption wave number of the OH vibration.

ABSTRAK. Pada perairan Sungai Bengawan Solo, limbah pewarna batik hasil produksi industri sekitar mencemari sungai dalam kadar rhodamine-B yang tinggi. Salah satu upaya yang efektif untuk mengatasi pencemaran di lingkungan perairan adalah melalui proses degradasi menggunakan fotokatalis dengan bantuan sinar-UV. Pada riset ini, digunakan fotokatalis carbon nitride nanosheets dengan doping zirkonium dan kobalt. Penambahan doping pada g-C3N4 nanosheets mampu meningkatkan kinerja fotokalitik. Tujuan penelitian ini adalah mengetahui pengaruh berbagai jenis doping terhadap kinerja fotoremediasi katalis carbon nitride nanosheets sehingga dapat menentukan jenis doping yang paling efektif dalam meningkatkan kinerja carbon nitride nanosheets untuk meredemidiasi limbah cair batik. Metode yang digunakan untuk mensintesis Co-doped g-C3N4 nanosheets dan Zr-doped g-C3N4 nanosheets dilakukan dengan sintesa g-C3N4 nanosheets murni menggunakan melamin dan amonium sulfat yang dikalsinasi pada suhu 600°C. Selanjutnya dilakukan impregnasi doping Zr dan Co pada g-C3N4 nanosheets menggunakan vacuum evaporator. Pengujian efektifitas katalis dalam mendegradasi rhodamine-B dianalisa menggunakan uji X-Ray Diffraction (XRD) dan Spektrofotometer UV-Visible. Hasil penelitian menunjukkan g-C3N4 nanosheets yang terdoping Kobalt dan Zirkonium dapat meningkatkan kemampuan mendegradasi rhodamine B. Berdasarkan data absorbansi dari fotokatalis yang diuji, fotokatalis Zr-doped g-C3N4 nanosheets menunjukkan hasil yang paling optimal dalam mendegradasi rhodamine-B dengan penurunan konsentrasi rhodamine-B hampir mendekati 0.Kata Kunci: Co-doped g-C3N4 Nanosheets, Fotokatalis, Fotoremediasi, Zr-doped g-C3N4 Nanosheets Abstract. Batik dye waste pollutes the Bengawan Solo River in high levels. One of the effective efforts to overcome pollution in the aquatic environment is through a degradation process using photocatalysts with UV-rays. In this research, carbon nitride nanosheets as photocatalyst with zirconium and cobalt doping was used. The addition of doping on g-C3N4 nanosheets was able to improve the photocatalytic performance. The purpose of this study was to determine the effect of various types of doping on the photoremediation performance of carbon nitride nanosheets. Synthesize Co-doped g-C3N4 nanosheets and Zr-doped g-C3N4 nanosheets was carried out by synthesizing pure g-C3N4 nanosheets using melamine and ammonium sulfate that calcined at 600°C. Afterwards, the mixture was impregnated by Zr and Co-doped using a vacuum evaporator. The effectiveness of the photocatalyst to degrading rhodamine-B was analyzed using X-Ray Diffraction (XRD) and UV-Visible Spectrophotometer. The result shows that photodegradation performance of Co and Zr-doped g-C3N4 nanosheets has increased. Based on the absorbance data of photocatalysts, the Zr-doped g-C3N4 nanosheets photocatalyst give the most optimal results in degrading rhodamine-B with the final rhodamine-B concentration close to zero.Keywords: Co-doped g-C3N4 nanosheets, Photocatalyst, Photoremediation, Zr-doped g-C3N4 Nanosheets
