Abstract

The purpose of this study was to determine the comparison of the characteristics of soil chemical properties with POC Marolis, mahogany leaf compost IPM Malang and its combination in Tlogowaru, Kedungkandang, Malang. This study lasted for 100 days (one planting season) in rice fields inpari 30 ciherang varieties. Data retrieval method with observation method which includes (1) phase before planting, (2) vegetative phase and (3) generative phase. Soil sampling was taken with a depth of 30 cm. Soil sampling was tested at the Laboratory of Soil Chemistry, Faculty of Agriculture, Brawijaya University, Malang. Parameters tested include pH, Organic C, total N, C / N, P Bray ratio, base cations (K, Na, Ca, Mg, KTK, KB). Based on the results of the study it can be concluded that the best treatment of the characteristics of the chemical properties of paddy soil is owned by a combination of POC and compost which has a relatively acidic soil pH when the vegetative and generative phases, organic C and N Total are classified as starting before planting up to the generative phase, K Base Cation is classified as moderate from the vegetative to generative phase, Na Base Cation increases to moderate when the generative phase, Ca starts before planting to the high generative phase, high KTK starts from planting to generative conditions.

Abstract

The research aim to make an spatial information system to determine Potential Erosion Index in Babakan watershed area to learning, testing, and evaluating erosion level using Geographical Information System (GIS). Spatial analysis that used are Digital Terrain Modelling (DTM)/Digital Elevation Modelling (DEM) that integrated with Moore and Burc (1986) equations. This analyze represented land surface relief in 3 dimension form to increase correctness of identification of land slope, catchment area, flow direction, flow accumulation, length of flow, and flowing area. The datas that used on this research are digital tophographic map 1:25000 scale, watershed boundary map, rivers network of Babakan watershed map, and landuse map. Analysis on this research is DEM processing from the countour map than integrated them to the Moore and Burch (1986) equations. The result of this research shown that minimum Potential Erosion Index value is 0 and maximum is 12244515840.

Abstract

Minyak goreng berfungsi sebagai media penghantar panas yang paling baik dalam pengolahan makanan. Penggunaan secara terus menerus dapat menyebabkan penuruan kualitas yang biasa disebut sebagai minyak jelantah. Konsumsi minyak goreng yang sudah dipakai berkali-kali dapat mengakibatkan keracunan dalam tubuh dan berbagai macam penyakit, seperti diare, pengendapan lemak dalam pembuluh darah, dan kanker. Tujuan penelitian ini adalah untuk mengetahui pengaruh suhu dan kecepatan putaran terhadap proses pemurnian minyak jelantah menggunakan ampas tebu. Tahapan penelitian ini meliputi pengolahan ampas tebu, proses pemurnian minyak dengan adsorbsi menggunakan variasi suhu 50, 60, dan 70 OC; dan kecepatan putaran pengadukan (50, 100, dan 150 rpm). Analisis mutu sampel meliputi pH, kadar air, asam lemak bebas dan bilangan asam. Variasi perlakuan terbaik yang digunakan untuk adsorbsi minyak jelantah menggunakan ampas tebu terutama dalam penurunan nilai asam lemak bebas paling optimal adalah pada variasi perlakuan suhu 70 OC dan kecepatan putaran pengadukan 150 rpm dengan nilai parameter masing-masing pH sebesar 6.61, kadar air sebesar 0.2469%, asam lemak bebas sebesar 0.30095, dan bilangan asam sebesar 2.24 %. Analisis statistik menunjukkan terdapat pengaruh nyata terhadap parameter kadar air, asam lemak bebas, dan bilangan asam, sedangkan hal sebaliknya pada parameter pH pada tingkat kepercayaan 95%.

Abstract

This community service is carried out at the location of the oyster mushroom cultivation business in the District of Dau AR-5 RT. 02 RW. 10 District of Malang. Under these business conditions, many oyster mushroom products rot and are wasted during the main harvest, especially when demand for mushrooms falls, because oyster mushrooms have a short shelf life or are easily damaged quickly. In addition, the process of making baglog for oyster mushroom cultivation is carried out through the process stages. One of the main processes is sterilization/pasteurization, which requires a high cost. This phenomenon was experienced by CV. Tower two started the oyster mushroom cultivation business in 2011. The method that will be applied is the community empowerment method for the SME group to increase the productivity and independence of partners economically and socially through counseling and mentoring efforts. Assistance or introduction of tools in the form of sterilization equipment and boilers for the process of making baglog and technology for the production of blanching mushroom products. The service results provide benefits to partners' production to increase with a capacity of 500 baglogs used 4x a week. Based on these calculations, there is an increase in efficiency and turnover from partners.ABSTRAKPengabdian Masyarakat ini dilakukan dilokasi usaha budidya jamur tiram yang berada di Kecamatan Dau AR-5 RT. 02 RW. 10  Kabubaten Malang. Dengan kondisi usaha saat, terdapat banyak produk jamur tiram yang busuk dan terbuang saat panen raya terutama pada waktu permintaan jamur turun karena jamur tiram memiliki umur simpan yang pendek atau cepat mengalami kerusakan. Selain itu, proses pembuatan baglog jamur tiram yang dilakukan melalui beberapa tahapan proses salah satu proses utamanya adalah sterilisasi/pasteurisasi membutuhkan cost yang besar. Fenomena hal ini dialami oleh CV. Menara dua yang dimiliki oleh Bapak Azhal Alam Islamy yang memulai usaha budidaya jamur tiram dari tahun 2011 yang sampai saat ini masih belum menemukan formula yang tepat dalam mengatasi masalah tersebut. Metode yang akan diterapkan yaitu metode pemberdayaan masyarakat kelompok UKM dalam upaya peningkatan produktivitas dan kemandirian mitra secara ekonomi, sosial melalui usaha penyuluhan dan pendampingan. Bantuan ataupun perkenalan alat berupa alat seterilisasi dan boiler untuk proses pembuatan baglog serta teknologi produksi produk jamur blanching sangat membantu mereka dalam memajukan dan mengembangkan usaha.
