Faktor-faktor yang Memengaruhi Persepsi Petani Beras Hitam Lokal di Daerah Istimewa Yogyakarta
Full text linkPenelitian ini bertujuan untuk mengetahui persepsi petani DIY terhadap beras hitam lokal, faktor-faktor yang memengaruhinya, serta mengetahui willingness to accept (WTA) petani. Persepsi petani terhadap beras hitam lokal beserta faktor-faktor yang memengaruhi serta WTA dapat menjadi rujukan untuk penyusunan strategi pemasaran. Metode pengumpulan data dilakukan dengan teknik purposive dan snowball sampling melalui pemberian kuesioner dan wawancara kepada petani beras hitam di Kabupaten Sleman, Bantul, dan Gunungkidul. Dari hasil analisis data, diketahui bahwa dari aspek biaya produksi, risiko kegagalan, kebutuhan air dan nutrisi, keberlanjutan produksi, kemudahan pemeliharaan, dan umur tanaman beras hitam sama saja dengan varietas beras lain. Sedangkan dari aspek produktivitas beras hitam lebih rendah dibanding dengan varietas beras lainnya. Faktor yang paling memengaruhi persepsi petani adalah faktor harga dengan nilai eigenvalue 3,616, kemudian faktor distribusi (1,669), faktor sosialisasi (1,422), faktor biaya produksi (1,212) serta faktor keunggulan produk (1,060). Dari perhitungan WTA, harga minimum yang petani bersedia terima adalah Rp19.800,00
Optimization of Skipjack Tuna (Katsuwonus Pelamis) Quality Factors in Chilled Box Storage Using Taguchi Method
No full textSkipjack tuna (Katsuwonus pelamis) is one of tuna fish species in Indonesia,which is perishable and must be kept its freshness by chilling. Aim of this research were to optimize influenced quality factors and to find the best method for reduce deterioration process. The research was conducted by using Taguchi Method, which was used quality robustness concept and multi-performance characteristics to achieve optimal combination of factors. Controlled factors during chilled storage were; weight ratio of ice and fish (A), box size (B), time replacing ice (C), ice form (D), concentration of added salt (E), fish form (F) and number of fishes per kg (G). Quality responses for assessing the freshness were; peroxide value (POV), water content (WC), pH value, texture and Total Plate Count (TPC). The result showed, increase of peroxide value was affected by A of 26.52% and C of 26.52%. Increase of water content was influenced by F of 37.25%. Fluctuation of pH was affected by G of 59.58%. Decrease of texture was influenced by A of 40.47%. Increase of TPC was influenced by A of 31.20%. Priority Scale of factors during storage were A, E, D, G, F, B, and C. Result of analysis muli-performance characteristics gave a conclusion that factors A1, B1, C1, D2, E2, F2 and G2 are the best chilling storage methods
Optimization of Production Process of Nano-Calcium Oxide from <i>Pinctada maxima</i> Shell by Using Taguchi Method
Full text linkWest Nusa Tenggara is a center of sea oyster farming for Pinctada maxima in Indonesia. The calcium carbonate (CaCO3) compounds in the shell are one of the decomposed natural minerals to produce calcium oxide (CaO) compound which is able to be used as an alternative heterogeneous catalyst in nanometer scale. This research aims to discover the control factors which influence the production process of nanometer-scaled CaO heterogeneous catalyst and choose the best condition in its production process with a better-quality product. Calcined pearl shell (P. maxima) powder is milled by using Shaker mill. The experimental design is performed by using Taguchi method with an orthogonal matrix consisting of 4 control factor variables, i.e. milling time, ball-to-powder weight ratio, the diameter of milling beads and extent of milling the vial. The selection of best control factor variable combination is computed by using multiresponse loss function. ANOVA analysis shows that the product quality parameter of nano-calcium oxide is influenced by all experiment factors. Multi-response loss function analysis results an optimum factor and level combination under process condition happens during the duration of 3 h milling, the ball-to-powder weight ratio is 1:10, the diameter of milling beads is 5 mm and 55% extent of filling the vial
Pengembangan Tortila Berkalsium Sebagai Alternatif Pangan Diet Casein Free-Gluten Free pada Industri Kecil dengan Metode Value Engineering
Full text linkThe number of people with autism increased 56% in 1998 – 2013, and it was a global problem. People with autism need special treatments and CFGF diet (casein free, gluten free) was one of those treatments. That’s why, the development The calcium content was expected to substitute the calcium from dairy consumption, which shouldn’t be consumed by people with autism. The method used in this product development was value engineering which separated in three steps: information, creativity, and analysis steps. Respectively, this research was also further completed with chemical The goal of this research was to design some product implemented in small scale industry. Respondends and panelist in this research were consisted of students and teachers. They acted as the market of the product, especially as a part of general society. This product were designed to provide CFGF snack for people with autism, and those who need CFGF diet. But this product was not limited to that market, it can be consumed by general society not only for people with autism, hence the students and teachers were used. The research showed that the best concept was a product produced with to get 200 grams of dough. This product concept was also designed to be packed in big size gusset packaging materials and the chips was triangle-shaped with size of feasible to be produced in small scale industry.ABSTRAKDengan jumlah penyandang autis yang terus meningkat, misalnya peningkatan sebesar 56% pada 1998 – 2013, maka produk tortila berkalsium potensial dikembangkan sebagai alternatif pangan untuk diet CFGF (casein free, gluten free) dan kandungan kalsiumnya bisa membantu menggantikan kalsium dari susu sapi yang mengandung kasein. Tujuan penelitian adalah merancang sejumlah konsep produk tortila berkalsium dan memilih satu konsep yang paling disukai Metode penelitian adalah yang terdiri dari tiga tahap: informasi, kreativitas dan analisa. Penelitian juga dilengkapi analisa lanjutan: analisa kimia guru, selaku masyarakat umum yang bisa mengonsumsi produk. Produk ini memang diawali dari adanya kebutuhan diet CFGF, namun konsumsi produk tetap bisa untuk umum sehingga produk bisa dikonsumsi semua kalangan, tidak terbatas hanya untuk penyandang autis yang perlu diet CFGF. Konsep terbaik yang diperoleh adalah tortila dengan komposisi bahan berupa rasio tepung jagung : tapioka sebesar 50:50 dan 3 g garam serta 7 g tepung tulang rawan ayampedaging, per 200 g adonan keripik. Konsep ini didesain dengan kemasan gusset ukuran besar, serta bentuk kepingan

Pola Produksi Etilen, Respirasi, dan Sifat Sensoris Beberapa Buah Pada Kondisi Udara Terkendali
No full textOne method to prolong the selflife of fruit is to control the atmosphere at a low temperature. In This research, the composition of the standard atmosphere (CO2 : 02 : N2) was 0,03% : 21% : 78%, and the composition of the control atmosphere of CO2 : 02 : N2 were (0% : 10% : 90%), (0% : 5% : 95%), (5%, 10%, 85%), and (5% : 90%). The research goal was to detect athylene production using a spectometer photoacustic, respiration rate using a respirator, and determine the sensory of fruit. The Fruits used in the research are apple (Mains syvestris Mill.), mangosteen (Garcinia mangostana L.), guava (Psidium guajava), chico (Manilkara Zapota Linn), avocado (Persea americana Mill.), and banana (Musa paradisiaca). The final results of the research suggested that generally fruits in control atmospheres determine ethylene production and respiration rate are lower than standart. The sensory of fruit in the control atmosphere is the same, too. The quality of fruits is the control atmosphere combinated temperature 10°C was better than the standart. The control atmosphere with composition CO2 5%, 02 5%, N2 90% resulted the best quality fruit
