Paradigma pendekatan pembangunan ekonomi berbasis pertanian telah mengalami perubahan, dari yang semula bertumpu pada pembangunan produksi pertanian (sub sistem budidaya/produksi), beralih pada pembangunan sistem dan usaha agribisnis dimana seluruh sub sistem agribisnis (budidaya, saprodi, pengolahan hasil pertanian, pemasaran produk, dan jasa) dibangun secara simultan dan harmonis. Sebagai salah satu aplikasi dari kebijakan industrialisasi pertanian, Pemerintah Kabupaten Malang pada tahun 2007 mulai mengembangkan Program Sentra Kawasan Agropolitan di Kecamatan Poncokusumo. Agar potensi sektor pertanian dapat dioptimalkan dalam penerapan konsep agropolitan, maka perlu dilakukan penelitian untuk mengidentifikasi komoditi pertanian unggulan di Kecamatan Poncokusomo. Dengan menggunakan analisis Location Quation (LQ), diperoleh hasil bahwa potensi komoditi unggulan untuk industrialisasi pertanian di Kecamatan Poncokusumo adalah ubi kayu dan jagung untuk sub sektor tanaman pangan dan palawija; apel, belimbing, dan kelengkeng untuk sub sektor tanaman buah-buahan; kentang, tomat, kubis, dan cabe besar untuk sub sektor tanaman sayur-sayuran; kopi arabika dan kelapa untuk sub sektor tanaman perkebunan rakyat; bunga krisan untuk sub sektor tanaman bunga; serta jahe untuk sub sektor tanaman rempah dan obat. Diharapkan pemilihan komoditi untuk industrialisasi pertanian dapat memaksimalkan potensi dari komoditi-komoditi pertanian unggulan tersebut.

Produksi bawang hitam di salah satu warga desa Sumbersekar, Dau, Kabupaten Malang cukup melimpah. Produk ini belum memberi dampak postif bagi warga sekitar, karena warga sekitar belum dapat mengembangkan produk tersebut sebagai komoditi yang dapat menarik minat wisatawan. Perlu dilakukan pelatihan pengolahan lanjut produk bawang hitam ini menjadi produk lanjutan. Teknologi yang dilatihkan adalah pembuatan minuman sari bawang hitam (dengan penambahan kayu manis dan perisa moka), dan pembuatan permen coklat isi bawang hitam. Metode yang digunakan pada pelatihan ini adalah dengan melakukan penyuluhan dan diskusi, serta demonstrasi, praktek dan konsultasi. Hasil pelatihan menunjukkan para peserta latih memahami teknologi yang diperkenalkan dan dilatihkan.

Galangal is one of Indonesia's spice plants and the rhizome contains chemical components, such as essential oils so that it can be used for various purposes, including medicinal, antimicrobial, cosmetic,abd antifungal. The essential oil content of red galangal rhizome is 0.3-1% depending on the quality of the rhizome. The process of extracting essential oils can be done by steam-water distillation. This study aims to determine the effect of temperature and drying time as a preliminary treatment before distillation. The study was designed using a Randomized Block Design with 2 factors: the first is the drying temperature (50oC; 60oC; 70oC), the second factor is the drying time (2; 4; 6 hours). The analysis was carried out yield, refractive index, specific gravity, color, and chemical components. The material used was red galangal rhizome which was approximately 1 year old. Steam and water distillation method was used for oil extraction for 6 hours. The results showed that the best treatment was the control treatment (without drying) with a yield of 0.076%, refractive index 1.4773%, specific gravity 0.8952 (g/ml), color L 23.365, color a* (-)0.995 , and color b* yellowish (+)3.78. Tthe GC-MS, 37 chemical components were detected, of which 6 main components were found with the highest area value, 1.8-Cineole 27.347%; (Z)-beta-Farnesene 11.641%; 2-Beta-Pinene 8.700%; Phenol, 4-(2-propenyl)-acetate (CAS) 6.369%; 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl)-(CAS) 4.305%; and cis-Ocimene 4.009%. The drying reduces the essential oil yield of galangal rhizome.

The further processing of coconut shell pyrolysis into liquid smoke has been developed in recent years. However, the common technology by directly condensing the smoke has many impurity compounds which decreases the yield of liquid smoke produced. Hence, in this study the cyclone separator was applied to increase the quality of physicochemical content in coconut shell-liquid smoke (CS-LS) grade C. The physical parameters analyzed were yield, pH, density and color. The chemical parameters was analyzed by GC-MS. The result showed that CS-LS processing with cyclone separator was able to increase the total yield into 3.33%, with better color, pH and density compared to the CS-LS produced using common method (direct condensation). The application of cyclone separator was also able to increase the phenolic compounds (97%), alcoholic compounds (92%), cycloalkene compounds (91%) and also decreased the benzoic acid, carbonyl and ester up to 100% compared with common method for CS-LS grade C production.

AbstractMoringa leaves are a source of high antioxidants. This study aims to find an equation model for the extraction conditions of Moringa leaves with Pulsed Electric Field (PEF) pretreatment. Fresh Moringa leaves were treated with PEF in various voltages (1,000, 1,500, and 2,000 Volts), frequency (1,000, 1,500 and 2,000 Hz) and extraction time (4, 5 and 6 hours) as the factors studied. The best results and mathematical equation models obtained were determined from the extraction process. The parameters observed were yield, total phenolic compounds, and antioxidant activity. The Response Surface Method (RSM) was chosen to determine the equation model for the voltage, frequency, and extraction time combination. The results of ANOVA (Sum of Squares, Lack of Fit, and p-value) show that the model is adequate to present experimental data. The analysis results showed a significant value for total phenol in a quadratic equation, extract yields in a linear equation, and antioxidant activity in a linear equation. The model is presented in a 2-D contour graph and a 3-D response surface. The equation model shows that the best treatment is a PEF voltage of 2,000 Volts, frequency of 1,000 Hz, and extraction time of 4 hours.Keywords: antioxidant, equation model, moringa leaf, Pulsed Electric Field, Response Surface Method AbstrakDaun kelor merupakan salah satu sumber antioksidan yang tinggi.

The production of safe food with a little to no artificial preservatives is the main and most important challenge for the food manufacturing industry. Increasing demand of using the safe preservatives has pushed the food industry to use the herbal or natural preservatives. The essential oil of the piper species consists of complex compounds like the monoterpene that has a power in the activity of the antioxidant and antibacterial. The object of research is the essential oil of piper species like the Piper nigrum, Piper betle, Piper retrofractum, Piper caninum, and Piper cubeba. The review methodology used in this research is the PRISMA flowchart (2020). PRISMA aims to identify the quality of papers and transparency of the number of articles. The objective of this research is to summarize the research related to the chemical content of the piper essential oil, the antioxidant and anti-microbe as the potential natural preservatives. The anti-microbe activity on the piper species shows the MIC score ranging from 1.5 to 12.8 mg/mL towards the standard of bacterial preservatives in preventing pathogens in foods. The essential oil of piper species has the higher antioxidant compared to the synthetic ones, like the BHA and BHT that have the score of IC₅₀ <50 mg/mL. The essential oil of piper species has the GRAS certification and “safe” as an additive in foods. Keywords: DPPH, Monoterpene, MIC, Sesquiterpene.
