The changing paradigm of the business environment is becoming increasingly dynamic. Supply chain can be a competitive strategy that can improve the ability of business competition to determine critical points in business processes. The supply chain process has a big impact on global business and commerce. Development of an effective supply chain is carried out through the development of network structures in the supply chain, especially for coastal agricultural land vegetables. Vegetables planted in coastal agricultural land have their own uniqueness, which is different from plateau plants because of the nature of the land. Research aimed to analyze the network structure and chain business processes of vegetable supply chain in the coastal agricultural land.

Catfish is one of the leading fishery commodities in Indonesia. Its production is high in the Special Region of Yogyakarta, that is, 45.44% of the total aquaculture production and 35.58% of the total aquaculture production. This study aimed to determine the type of marketing channels, including the conduct and performance of catfish marketing, and the efficiency of catfish marketing in the Special Region of Yogyakarta. Samples were obtained through purposive and snowball sampling, and data were collected through in-depth interviews with 30 respondents and examined through descriptive analysis and an SCP approach focusing on conduct and performance analysis. Result showed that two marketing channels were available. The first type consisted of fish farmers, collectors, and retailers, and the second type included fish farmers and retailers. Market conduct analysis revealed that the determination of the catfish price was dominated by collectors, marketing costs varied among players, and the government did not intervene with its trade. Market performance analysis indicated that fish farmers received 71.98% of their share on marketing channel 1 and 80.49% on marketing channel 2. The profit-to-cost ratios of collectors and retailers were 1.31 and 0.29 in marketing channel 1, respectively. In marketing channel 2, the profitto-cost ratio of retailers was 1.65. Therefore, marketing channel 2 was more efficient than marketing channel 1.

White rice has become the main source of carbohydrates, but in the last few years, red and black rice are getting more popular. Red and black rice can be an alternative food for people who wish to reduce the risk of diabetics due to its low glycemic index. Pigmented rice demand in Yogyakarta is continuously increasing. However, farmers are reluctant to plant pigmented rice because of their lower yields. Value chain analysis on pigmented rice is performed to provide the condition of the business’ performance for farmers who are not willing to work on pigmented rice yet. The objective of this study was to identify the main activities and to measure the performance of the value chain. The value chain performance was measured by calculating profit, marketing margin, and farmer’s share. In the business of pigmented rice nowadays, there are 5 actors involved, i.e. farmer, farmers group, association of farmers groups, distributor, and retailer. These five actors formed 5 value chains for red rice and 4 value chains for black rice. The main activities were cultivating, cropping, milling, sorting out, packing, and selling. The performance of the pigmented rice was as follows: on the red rice value chain, farmers earned the highest profit in each chain, except on the chain where the association of farmers groups was involved. The largest marketing margin was found on the farmer – association of farmer groups – retailer – end-user consumer chain. On the black rice value chain, farmers earned the highest profit in each chain, except on the chain where the farmers group was involved. The largest marketing margin found on the farmer – farmers group – distributor – retailer – end-user consumer chain. For both the red and the black rice value chain, the farmer’s highest share was obtained on the farmers – distributor – end-user consumer chain.

Pengembangan Sistem Pendukung Keputusan (SPK) pada studi kelayakan pemilihan lokasi agroindustri dengan analisis finansial dan lingkungan belum banyak dilakukan, khususnya untuk kelayakan industri sekala kecil menengah di area permukiman. Penelitian ini bertujuan membuat rancang bangun sistem pendukung keputusan (SPK) pemilihan lokasi agroindustri dengan kombinasi analisis finansial dan spasial lingkungan. Studi dilakukan untuk penetapan lokasi industri tahu di Daerah Istimewa Yogyakarta (DIY). Penelitian dilakukan melalui tahapan perancangan context diagram, hierarchical input process output (HIPO), dan data flow diagram. Sistem dirancang dengan 2 desain antarmuka: untuk user (interface front end) dan antarmuka oleh admin (interface back end). Hasil penelitian adalah prototype aplikasi pendukung keputusan berbasis website bernama IFSS (Industrial Feasibility Support System) dengan alamat domain http://ifssugmku.com/. Pemilihan lokasi industri dengan kriteria finansial dan lingkungan dilakukan untuk menentukan lokasi yang paling sesuai bagi pendirian industri. Uji coba sistem menunjukkan Kabupaten Gunungkidul merupakan lokasi dengan hasil kelayakan finansial tertinggi dengan nilai NPV (Rp) 879.520.243, sementara Kabupaten Bantul dan Kulon Progo merupakan daerah dengan sebaran lokasi terpilih tertinggi dari analisis lingkungan menggunakan teknik overlay. Verifikasi dilakukan dengan membandingkan hasil perhitungan manual dengan hasil perhitungan aplikasi, serta membandingkan sebaran lokasi keberadaan 14 sampel industri tahu di DIY dengan hasil pemilihan lokasi secara spasial pada ArcGIS Pro. IFSS adalah aplikasi untuk membantu memberikan petimbangan pemilihan lokasi industri secara finansial dan lingkungan.

Pigmented rice may have a black or red color due to higher anthocyanin content in its grain. A natural antioxidant, many studies on anthocyanin have reported its positive effects on human health. This fact has spurred the development of pigmented rice as a functional food. This study aimed to compare the metabolite profiles of black and red rice. Three black rice cultivars, namely Melik, Pari Ireng, and Cempo Ireng Sleman, and two red rice cultivars, Inpari 24 and RC 204, were used. After husk removal, grain samples were ground in liquid nitrogen and dried with a freeze dryer. The dried samples were extracted using 50% MeOD4 (in a D2O phosphate buffer pH 6 containing 0.01% TSP as an internal standard). Metabolomic analysis was performed using 500 MHz NMR followed by multivariate data analysis. An orthogonal partial least squares-discriminant analysis (OPLS-DA) model ađer PCA was constructed to discriminate between the five different cultivars. The resulting OPLS-DA score plot revealed a clear separation between black rice and red rice. The metabolites that could influence the separation of red rice and black rice were valine, threonine, alanine, glutamate, galactinol, β-glucose, α-glucose, raffinose, and fumaric acid.

Fresh cut flower has characteristis such as perishable and short shelf life. Pulse treatment is akind of method that can prolong fresh cut flower’s shelf life. Pulse treatment is a postharvesthandling which is done by soaking the stem of flower into a solution containing nutrients(glucose and sucrose) and germicides. The objectives of this reseacrh were to determine the bestalternatives of pulse treatment and determine shelf life of fresh cut rose flower of eachtreatment. There were 6 alternatives, namely P 1 (5% sucrose+20 mg/l AgNO 3 ), P 2 (150 mg/lAgNO 3 ), P 3 (1,2% sucrose+0,2 mM STS), P 4 (5% sucrose+20 mg/l AgNO 3 +320 mg/l citricacid), P 5 (1,2% sucrose+ 0,2 mM STS+ warm water (40 0 C)), P 6 (5% sucrose+20 mg/lAgNO 3 +320 mg/l citric acid+warm water (40 0 C)). The parameters used for determining shelflife are color of petals (lightness and redness), moisture content, and texture of stem. As results,shelf life of P1 was 8 days, P2 was 6 days, P3 was 4 days, P4 was 6 days, P5 was 5 days, andP6 was 5 days. All of the alternatives gave longer shelf life than control (4 days). The bestalternatives was P1 with 8 days shelf life. Moisture content in that day was 78,313%, texture ofstem was 47,0603 N, lightness was 31,237 and redness was 46,942.
