Abstract

The effect of nickel precursors and the temperature annealing to obtain intermetallic Ni3Sn2 alloy catalysts on its activity and selectivity in the selective hydrogenation of biomass-derived furfural (FFald) were investigated. Two types of nickel precursors (c.a., i) nickel metal (Ni°) derived from Raney®nickel and ii) nickel ion (Ni2+) derived from nickel chloride) were employed as the starting materials via hydrothermal at 423 K for 24 h followed by reduction with H2 at the elevated temperature of 573-873 K for 1.5 h. The physico-chemical properties of the intermetallic Ni3Sn2 were characterized by XRD, N2-, and H2-adsorption, ICP-AES, and NH3-TPD. The intermetallic Ni3Sn2 alloy catalysts, both bulk and supported, demonstrated high activity and selectivity towards hydrogenation of FFald. The activity and selectivity of g-Al2O3 and AA-supported Ni3Sn2 alloy catalysts in the hydrogenation of FFald to furfuryl alcohol (FFalc) were maintained even after annealing at up to 873 K, but that of bulk Ni3Sn2 drastically dropped. Ni-Sn alloy catalysts which were obtained from Raney®Ni precursor showed more stable than that of nickel salts during hydrogenation of furfural to furfuryl alcohol.

Abstract

Pondok Pesantren Mahad Arrahman telah memanfaatkan energi terbarukan berupa sel surya untuk mengurangi pemakaian energi listrik, dan juga berfungsi sebagai energi cadangan ketika terjadinya pemadaman listrik. Namun, kendala lain muncul pada pemanfaatan energi sel surya ini, yaitu daya yang terpasang masih tidak mampu mencukupi kebutuhan pondok pesantren akan listrik. Penurunan performa ketika proses charging di siang hari yang terasa lebih lambat, dibandingkan waktu menjelang siang. Salah satu penyebabnya adalah ketika temperatur meningkat terjadi penurunan performa sel surya. Untuk itu diperlukan tambahan energi listrik berupa panel surya beserta instalasinya dengan teknologi berpendingin air. Kegiatan pengabdian masyarakat ini meliputi perancangan alat teknologi sel surya berpendingin air yang diharapkan dapat membantu mengatasi permasalahan di Pondok Pesantren Mahad Arrahman. Luaran kegiatan ini adalah berupa pemahaman dan transfer keterampilan teknologi sel surya berpendingin air dan Alat yang terdiri dari Sel Surya, Pompa air DC, Pipa Instalasi jalur air, Saklar, Kontroler, Inventer, dan Baterai. Manfaat dari kegiatan ini adalah terjadinya penambahan daya listrik menggunakan energy tenaga surya dan diharapkan terjadinya penurunan temperature setelah dipasang teknologi pendingin air sehingga terjadi peningkatan performa sel surya.

Abstract

Indonesia mempunyai potensi energi matahari yang cukup besar, karena terletak didaerah tropis. Energi surya adalah energi yang sangat bersahabat karena tidak bersifat polutif, tidak dapat habis dan gratis. Mushola Nurul Hikmah sebagai salah satu pusat peribadatan yang berada di daerah Kelurahan Loktabat Utara Banjarbaru Utara mempunyai motto pengembangan mushola bernuansa hijau baik dari segi tata letak, tata kelola lingkungan, maupun sumber energi yang digunakan. Dari segi tata kelola dan tata letak lingkungan, pihak pengurus Mushola telah menempatkan taman hijau dan perkebunan hidroponik. Dari segi sumber energi listrik, mereka masih menggunakan sumber utama dari PLN dan genset. Kelemahan genset terkait masalah polusi dan suara yang mengganggu kekhusyuan peribadatan. Pihak pengurus mushola beberapa kali mendapatkan keluhan dari Jamaah terkait dengan suara kebisingan tersebut sehingga sangat diperlukan solusi yang lebih efisien baik dari segi daya maupun polusi yang ditimbulkan. Salah satu teknologi energi yang bisa dimanfaatkan dengan minim polusi udara dan suara adalah teknologi panel surya yang bisa mengkonversi langsung intensitas cahaya matahari menjadi sumber energi listrik alternatif. Hal-hal yang perlu diperhatikan dalam perancangan panel surya adalah: besarnya beban total yang akan digunakan, jumlah Modul yang diperlukan, jenis atau karakteristik Modul yang akan dipilih, posisi lintang lokasi dimana system SHS akan dipasang dan besarnya kapasitas AKI yang diperlukan. Apabila akan dilakukan instalsi secara bertahap sesuai perencanaan anggaran, maka kapasitas daya AKI dan Panel surya seterusnya idealnya harus sama dengan yang sebelumnya sudah terpasang, agar tidak terjadi overcharge dan overload. Dengan mengikuti langkah-langkah perencanaan yang telah diuraikan diatas, maka kesesuaian antara kebutuhan, harga, dan kualitas akan dicapai. Kata kunci: energi surya, beban total, Modul, posisi lintang, kapasitas AKI

Abstract

Penelitian ini memiliki tujuan untuk mengeksplorasi dampak variasi arus pengelasan GMAW terhadap distorsi dan kekerasan pada material baja ST37 setelah dipanaskan pada suhu 400˚C. Hasil penelitian mengenai variasi arus dan perlakuan post heating pada suhu 400°C di daerah HAZ dan pada area Weld Metal menunjukkan perbedaan yang signifikan dalam nilai kekerasan. Perbedaan ini dipengaruhi oleh variasi arus yang diberikan; semakin tinggi arusnya, semakin besar pula pelunakan logam yang terjadi. Sebagai contoh, pada arus 100 A, nilai kekerasan tercatat sebesar 65 HRB, sedangkan pada arus 120 A, nilai tersebut turun menjadi 56,4 HRB. Di bagian Weld Metal, nilai kekerasan tertinggi terlihat pada arus 80 A (59,8 HRB), dan nilai terendah terdapat pada arus 120 A (51,1 HRB). Dari ketiga perbedaan suhu yang diberikan kepada spesimen dengan arus yang berbeda, yaitu 80 A, 100 A, dan 120 A, memiliki nilai distorsi rata-rata tertinggi pada arus 80 A (1,17 mm), diikuti oleh arus 100 A (0,85 mm), dan terendah pada arus 120 A (0,68 mm). Hasil penelitian uji distorsi ini menunjukkan bahwa perlakuan post heating sangat berpengaruh terhadap nilai distorsi pada spesimen tersebut. This study seeks to investigate the impact of varying GMAW welding currents on distortion and hardness in ST37 steel material post-heating at 400˚C. The research findings on the variations in current and post-heating treatment at 400°C in both the HAZ (Heat Affected Zone) and Weld Metal areas reveal significant differences in hardness values. These differences are attributed to variations in the current supplied; the higher the current, the greater the metal melting (softening) observed. For instance, at 100 A, the hardness value is recorded at 65 HRB, while at 120 A, it decreases to 56.4 HRB. In the Weld Metal section, the highest hardness value is observed at 80 A (59.8 HRB), and the lowest is at 120 A (51.1 HRB). Among the three different current levels (80 A, 100 A, and 120 A) applied to spesimens, the average distortion value is highest at 80 A (1.17 mm), followed by 100 A (0.85 mm), and lowest at 120 A (0.68 mm). These results underscore the significant impact of post-heating treatment on the distortion of the spesimen.

Abstract

Sunlight can be harnessed as a clean and renewable energy source using solar cells and the photovoltaic process. However, relying on direct sunlight exposure can increase solar cell temperatures and negatively impact performance. This research aims to maintain cell efficiency by exploring the effectiveness of spraying coolant media on the bottom surface of panels through three timed intervals (10, 20, and 30 minutes) using three different media (A, B, and C). Each spray application lasts for 1 minute. Analyzing the test results with Minitab18 software with full factorial design will identify the most effective treatment for maintaining performance. Based on the results of the experimental test, coolant A with a 10-minute delay spraying time has a maximum power of 52.89 Watts, a temperature of 48oC, and an efficiency of 5.69%. Response Optimization using Design of Experiment (DOE) Full Factorial shows an optimal response with coolant A and a 10-minute delay spraying time with the lowest temperature at 49.3oC, maximum output power at 46.87 Watts, and efficiency at 5.61%. Moreover, Tukey Krammer test result provides an information about 10-minute delay spraying time has a better performance to reduce the PV panel temperature compared to 30-minute delay spraying time by 3.94 oC.
