Telah dilakukan hidrorengkah minyak laka menjadi fraksi berpotensi energi menggunakan katalis zeolit alam teraktivasi asam (ZAA), yang selanjutnyna diimpregnasi dengan unsure unimetal (NiO) dan bimetal (NiOMoO), dimana menjadi dua jenis katalis (NiO/ZAA dan NiOMoO/ZAA). Tujuan dari penelitian ini adalah untuk mengetahui potensi konversi minyak laka menjadi fraksi berpotensi energi serta mengetahui pengaruh impregnasi logam pada katalis ZAA terhadap kemampuan dalam reaksi hidrorengkah. Karakterisasi katalis meliputi penentuan tingkat keasaman menggunakan adsorpsi basa ammonia dan kristalinitas menggunakan difraksi sinar X (XRD). Aktivasi asam dan impregnasi logam meningkatkan keasaman dan kristalinitas katalis. Reaksi hidrorengkah dilakukan dengan menggunakan reaktor fixed bed pada temperatur reaksi 450 oC, rasio umpan/katalis=6 dengan laju alir H2=20 ml/menit. Hidrorengkah mengkonversi minyak laka menjadi fasa cair, fasa gas dan fasa padat (kokas), yang berpotensi energi, dan konversi tiap fraksi telah dipelajari. Produk fasa cair selanjutnya dianalisis menggunakan kromatografi gas (KG), dimana menunjukkan bahwa fraksi cair hasil GC didominasi oleh gasolin, minyak solar dan minyak berat. Tiap fraksi yang terelusidasi menunjukkan selektivitas berdasarkan luas area hasil elusidasi GC untuk tiap fraksi terhadap total luas area GC keseluruhan fraksi cair. Hidrorengkah berkemampuan optimal menggunakan katalis NiOMoO/ZAA dengan mengkonversi minyak laka menjadi produk cair, serta selektivitas tertinggi juga terhadap fraksi gasoline dan diesel, masing-masing sebesar 38,45% dan 19,87%. Impregnasi unsur logam, khususnya bimetal (NiOMoO) pada katalis ZAA mengindikasikan peningkatan kemampuan dalam reaksi hidrorengkah.

Bioenergy is new and renewable alternative energy which is currently developed enthusiastically. Bioenergy could be produced by catalytic cracking method, which is cracking carbon chain to raise energy fraction. This paper observes potential non-food bioenergy of cashew nut shell liquid as an alternative bioenergy source using catalytic cracking method. The effect of impregnated-metals Nikel and Molibdenum catalyst used in hydrocracking of Cashew Nut Shell Liquid (CNSL) into bioenergy was investigated. It focused specifically on two type of natural activated zeolite catalysts: NiO and NiOMoO at temperature reaction of 450oC and ratio feed catalyst of 2 and 4. Catalysts characterization was conducted according to a gravimetric method to determine acidity of catalyst; Spectroscopy FT-IR analysis to get distribution of active site catalyst; X-Ray Diffraction (XRD) analysis to observe crystalinity of catalyst; and Gas Sorption Analyzer (GSA) to measure surface area, porosity and total of pore volume. Bioenergy of CNSL in the liquid-phase, which were predominantly by gasoline, diesel oil, and heavy oil, was further analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to determine the compound energy fraction qualitatively and quantitatively. The result showed that the NiOMoO (natural activated zeolite) provided an optimal performance with liquid product conversion was about 65-75%, and selectivity gasoline as well as diesel fraction was about 37-47% and 22-31%, respectively.

Telah dilakukan penelitian terhadap rancang bangun sistem monitoring parameter kualitas udara (suhu, CO, LPG dan debu) yang datanya terintegrasi secara real time. Alat ukur menggunakan basis mikrokontroler Arduino Uno R3. Sensor gas MQ-9 dan MQ-5 digunakan untuk mengukur polusi udara, sedangkan sensor LM35 dan DSM 501A digunakan untuk suhu dan debu. Sistem ini juga terhubung dengan Xbee S2 sebagai pengirim dan penerima data berbasis WIFI. Sumber tegangan dihubungkan ke panel surya 10 W yang diatur oleh charger controller sehingga ketika baterai penuh, koneksi pengisian baterai akan terputus. Perangkat lunak yang digunakan adalah Arduino IDE 1.8.1 dan X-CTU. Data yang dapat diukur dengan alat ini adalah tingkat pencemaran udara gas CO dan LPG, suhu udara dan partikulat PM 2.5 di udara. Tahap pengukuran diuji dengan sampel gas (CO dan LPG) serta sumber panas dan sumber dingin untuk suhu. Data pengujian menunjukkan bahwa semua sensor mampu mendeteksi keberadaan gas CO dan LPG, perbedaan suhu dan kadar debu di udara kemudian menampilkan data tersebut secara real time.

This training was designed to introduce ecoprint techniques to members of the Women's Dharma Association of the West Papua Provincial Forestry Service, emphasizing its potential as a community-based business opportunity. The activity utilized natural materials readily available in the surrounding environment, such as butterfly pea leaves and flowers, teak leaves, and other local foliage. The training was conducted in stages, beginning with an introduction to the basic concepts of eco-printing, followed by hands-on practice using two main techniques: pounding and steaming. These techniques were applied to cloth tote bags and ceramic mugs. The results showed that participants demonstrated a higher level of proficiency in producing eco prints using the steaming technique compared to the pounding method.

Hydrocracking of cashew-nut shell liquid (CNSL) into energy-affording fractions has been investigated using catalyst of acid-actiated natural zeolite (ZAA), to which were further impregnated unimetal (NiO) and bimetal (NiOMo) elements, thereby comprising two catalyst types (NiO/ZAA and NiOMoO/ZAA). This research aimed to examine how potential was the conversion of CNSL into energy-affording fractions, and to look into such metal impregnation into ZAA catalyst on the performance of hydrocracking reaction. Catalyst characterization included determining consecutively acidity using ammonia-base adsorption, and crystallinity using X-ray diffraction (XRD). Acid activation and metal impregnation increased the catalyst acidity and its crystallinity. The hydrocracking was carried out in a fixed-bed reactor employing the temperature 450°C, the CNSL feed/catalyst ratio of 6, and flow rate of H₂ at 20 ml/minute. The hydrocracking converted the CNSL into products that comprised the liquid-phase, gas-phase, and solid-phase (cokes) fractions, which in all afforded energy, and the conversion of each was examined. The liquid-phase product was further analyzed using gas chromatography (GC), which revealed that the GC's eluted liquid fraction were predominantly gasoline, diesel oil, and heavy oil. Each eluted fraction was further examined for its selectivity based on the elucidated GC area for each fraction over the total GC area for the overall liquid fractions. The hydrocracking performed optimally using NiOMo/ZAA catalysts. Which converted as much 75.42% (the greatest) of the CNSL as the liquid product, with also the greatest in selectivity towards gasoline and diesel-oil fraction at 38.45% and 19.87%, respectively. The impregnation of metal element, particularly bimetal (NiOMo) into ZAA catalyst indicatively enhanced the hydrocracking performance.
