Virus covid 19 telah menyebabkan tingkat pertumbuhan perekonomian Indonesia turun drastis atau berjalan sangat lambat. Hal ini di sebabkan oleh banyaknya tenaga kerja yang di rumahkan dan bahkan berhentikan sehingga minat jual dan beli kurang, tingkat pengangguran naik dan bahkan dapat menimbulkan peningkatan kriminalitas. Permasalahan ini harus segera di carikan solusi supaya tingkat kemiskinan tidak bertambah. Salah satu metoda yang di lakukan adalah pemberdayaan masyarakat untuk meningkatkan perekonomia yaitu dengan beternak bebek pedaging (mentok) dan bebek petelur dihalaman rumah. Mentok dan bebek petelur merupakan makanan yang banyak di gemari oleh masyarakat Yogyakarta karena banyak mengandung protein dan vitamin. Hal ini merupakan suatu peluang besar untuk pemberdayaan masyarakat dalam meningkatkan tingkat perekonomian. Program pemberdayaan ini dilakukan dengan kerjasama antara Direktorat Penelitian dan Pengabdian kepada Masyarakat Universitas Islam Indonesia (DPPM UII) dan Masyarakat mitra sebagai target program Pengabdian Kepada Masyarakat (PkM). Pemilihan mitra berdasarkan hasil survei yaitu Dusun Pandanpuro, Sleman, Yogyakarta. Program ini telah memberikan hasil yang sangat baik dimana Dusun Pandanpuro telah memiliki 2 (dua) mesin penetas telur dengan kapasitas masing masing 40 butir, peralatan pencacah sayuran dan buku panduan beternak serta menajemen kewirausahaan Tingkat keberhasilan mesin penetas telur mencapai 80 persen sehingga selama pengabdian masyarakat target telah memiliki rata-rata 32 ekor mentok atau bebek petelur. Untuk keberlanjutan program ini maka mesin penetas telur di gilir kemasyarakat lain yang dikendalikan oleh ketua kelompok tani

Nancomposite of Al2O3/activated carbon was prepared from the mixture of alumina oxide (Al2O3) and activated carbon from palm oil shell under the mixture of aquabidest and ethanol (1:1). The mixture was treated by hydrothermal process at 250 oC for 3 h. Resulted Al2O3/ activated carbon was characterized using SEM/EDX for studying the morphology structure of activated carbon and composite showing a like flower structure attached on the surface. The chemical compositions were 73.18%, oxygen 23.72%, aluminium 2.30%, dan silica 2.00%. The efficiency of composite was investigated for removal of phenol in aqueous solution. The maximum adsorption of phenol was obtained at pH 2, adsorbent weight 2 g, contact time 60 min and phenol concentration 100 ppm.

The bimetallic oxide NiO-CdO/biochar catalyst was prepared by coprecipitation and calcination methods. Characterizations of catalyst were carried out using Fourier Transform Infra Red (FTIR), Surface Area Analyzer (SAA), X-ray Diffraction (XRD), and Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX) mapping methods. The catalyst showed a good average crystalized size of 12.30 nm related to the nanoparticles and high dispersion of Ni and Cd metals on the biochar surface. Analysis of liquid fuel products was observed using Gas Chromatography - Mass Spectrometry (GC-MS) which was separated to the main product of gasoline fraction (C6–C10), and the second product of kerosene fraction (C11–C16), and diesel fraction (C17–C23). The presence of the catalyst in the hydrocracking resulted in more liquid product of 56.55 wt% than the thermal cracking with a liquid product of 20.55 wt%. The best performance activity of catalyst was found at a temperature of 150 °C with high selectivity to hydrocarbon fuel with 12 types of gasoline fractions (39.24 wt%) compared to gasoline fractions obtained at higher hydrocracking temperatures of 250 °C and 350 °C. The results of this study showed that the bimetallic oxide catalyst supported with biochar from palm kernel shell plays an important role in the hydrocracking process to increase the selectivity of the gasoline fraction.

Permintaan akan telur dan daging bebek di Kabupaten Sleman diprediksi akan terus meningkat sejalan dengan kemajuan industri pariwisata. Usaha beternak bebek dan mentok memiliki potensi yang besar untuk meningkatkan perekonomian masyarakat. Keuntungan beternak bebek dan mentok misalnya adalah harga telur dan daging, serta kandungan gizinya yang lebih tinggi daripada ayam. Pemeliharaan bebek/mentok adalah mudah. Bebek tidak mudah teserang penyakit ataupun memerlukan kandang khusus untuk pemeliharaanya. Mitra untuk kegiatan pengabdian ini adalah petani dan calon petani bebek yang ekonominya sangat terbatas, beberapa mitra telah memiliki beberapa ekor bebek yang dipelihara sebagai hobi, namun mitra berkeingin mengembangkan usaha beternak bebek yang lebih serius. Lokasi mitra adalah RW 21/RT04, Dusun Pandanpuro, Hargobinangun, Kecamatan Pakem, Kabupaten Sleman, Yogyakarta. Tujuan kegiatan pengabdian ini adalah membentuk mitra yang memiliki usaha mandiri beternak bebek dan mentok. Metode yang digunakan adalah mengembangkan ternak bebek/mentok melalui 3 program, yaitu: 1). Teknik beternak mentok dan bebek secara modern, 2). Pengadaan mesin penentas telur, alat pemotong sayuran dan campuran pakan bebek; 3). Penyuluhan kewirausahaan kepada mitra meliputi perencanaan, pengorganisasian dan pengawasan sebuah unit usaha.

The objective of this research was to prepare low-cost catalyst for green diesel conversion from vegetable oil. The catalyst of nickel-dispersed biochar (Ni/BC) was prepared by direct pyrolysis of nickel precursor with palm leaves waste under N2 stream at 500 °C. The obtained catalyst was examined by using x-ray diffraction, scanning electron microscope-energy dispersive x-ray, transmission electron microscopy, gas sorption analysis, FTIR and surface acidity examination. The catalytic activity testing was performed on rice bran oil hydrodeoxygenation at varied temperature and time of reaction. Based on analyses, the results showed the successful preparation of Ni/BC with the characteristic of single nickel nanoparticles decorated on surface. The increasing specific surface area of material was conclusively remarked the surface area enhancement by nickel dispersion along with the increased surface acidity, suggesting that the material can be applied for acid catalysis applications. The Ni/BC exhibited excellent catalytic conversion of rice bran oil with the high selectivity toward diesel fraction with 85.3% yield and 92.6% selectivity.

Oil palm shell was used as a precursor for preparation of activated carbon using different chemical activations (potassium hydroxide (KOH), zinc chloride (ZNCl2), and phosphoric acid (H3PO4)). Each activated carbons (AC) was mixed with nano-zinc oxide to form a composite. From the gas sorption analyzer, it is showed that nitrogen adsorption isotherms show Type II for ZnO/AC-KOH and ZnO/AC-ZnCl2 corresponding to the micro- and mesoporous structures, respectively. However, the nitrogen adsorption isotherm of ZnO/AC-H3PO4 exhibits the Type I with predominantly microporous structures. The SEM micrographs produced unsmooth surface and different pore sizes. The XRD patterns at 2θ of 25.06° and 26.75° were come from amorphous activated carbon. The peak intensity of ZnO was weak due to low concentration of zinc precursor. However, the ZnO of ZnO/AC-ZnCl2 showed strongly peak intensity. The effectiveness of the composites was examined for phenol removal determined by UV-Vis Spectrophotometer method. The equilibrium adsorption follows the Langmuir and Freundlich models according to the best correlation coefficient (R2). The kinetic model was only obtained for the pseudo-second-order with the best linearity of the correlation coefficient (R2). The results of this study showed that the oil palm shell has a great potential for ZnO/AC with excellent adsorptive property. Copyright © 2021 by Authors, Published by BCREC Group.
