The aim of this study was to determine the effect of storage temperature on the antioxidant activity of Sargassum hystrix. Samples were collected from Sepanjang Beach Gunung Kidul, Yogyakarta, and dried, pulverized, and then stored for two months at room temperature (17-33 °C), refrigerator (4 °C) and freezer (-18°C). Furthermore, the samples were tested every two weeks to determine their water content, total phenol, DPPH, and FIC. Also, Gas Chromatography-Mass Spectrometry (GC-MS) analysis was performed for two months before and after storage. The results showed that the water content increased after treatments, along with storage time which ranges from 8.55 to 14.27 %. Total phenol before storage was 175.73 mg GAE/g extract, and freezing has the highest total phenol levels after storage which was 22.07 mg GAE/g extract. Also, DPPH testing showed S. hystrix has anIC50 value of 0.45 mg/mL, and refrigeration has the lowest IC50 value of 3.18 mg/mL. FIC test showed IC50 value of 1.44 mg/mL, and freezing has the lowest FIC IC50 value of 15.36 mg/mL. In addition, GC-MS sample analysis before storage detected 8 compounds with antioxidant activity of 86.96 %. After two months, they were detected at room temperature, refrigerator, and freezing which are 4, 3, and 8 compounds respectively.

Seaweed is among fishery commodities with great potential economy prospect. Southeast Maluku District is one of the main producers in Eastern region of Indonesia. Despite the high production since 2012, the number of farmers and the product has declined due to inadequate supply chain coordination and information dissemination among members. Therefore, this study aimed to mitigate the assymetric information in the region using the house of risk (HOR) to identify the risks to be addressed, and also provide response on the source of supply chain risk. Furthermore, Analytic hierarchy process (AHP) with fuzzy approach was used to determine the major factor, and then choose the best alternative to mitigate asymmetric information in the supply chain. Results showed there were five factors that contributed 70% risks. The results also indicated that dependence on local distributor was a factor that had to be prioritized and addressed. In addition, to mitigate the operational risks, findings showed it is necessary to establish seaweed farmers forum, which is the best approach based on the cost and effectiveness. This study also stated that local ,government of Southeast Maluku District was the main actor that helps to overcome the risks and asymmetric information problem. Therefore, the best alternative was to form an information center for seaweed cultivation, which will provide the knowledge of prices and potential buyer outside the region.

Virgin coconut oil (VCO) is a pure coconut oil made from mature and fresh coconut meat. VCO is consumed for health-related reasons, but the unsaturated fatty acids of VCO are prone to oxidation. Mixing VCO with peppermint oil, which contains antioxidants, inhibits the oxidation of unsaturated fatty acids and thus prevents the rancidity of VCO. This research used the antioxidants from peppermint oil to improve VCO quality. VCO contains antioxidants, such as α-pinene, menthol, 1,8-cineol, camphor, flavonoid, borneol, tocopherol, and carotene. The treatments consisted of three peppermint oil concentrations (2.5%, 5%, and 7.5%) in VCO. Results showed that the additionof peppermint oil significantly improved VCO quality. The optimal concentration of peppermint oil in VCO was 7.5% with a water content of 0.05%, a free fatty acid value of 0.13%, a peroxide value of 0.53 mg eq/kg, an iodine value of 4.42 g I2/100 g, a total plate count of 0 cfu/mL, and antioxidant activity of 90.28%.

Despite of hydrophilic, glucomannan solubility is so slow that its solubility increase is required for easier, faster, and wider application. This research objective was to find a milling method which can enhance glucomannan solubility with high sol transparency, WHC and apparent viscosity. Native glucomannan extract from porang corm was classified into 3 treatments, no milling (native), grinding to pass through 80 mesh sieve (dry milling) or before grinding, the glucomannan were dissolved and precipitated using ethanol (wet milling) which then dried and passed through 80 mesh sieve. Compared to dry milling (13%), wet milling could significantly enhance higher glucomannan solubility (18%) with high sol transparency, WHC and apparent viscosity due to its depolymerization, molecular weight reduction, more porous and amorphous morphology as well.

Dietary fiber and resistant starch are known to be beneficial in lowering both glucose and lipid concentration in human. Fibercreme, a fiber rich product has been developed. It is a commercial non-dairy creamer that uses various oligosaccharides such as Isomaltose-oligosaccharides (IMO) or inulin as fiber source to replace the glucose component of conventional creamer. In this study, IMO and fibercreme were used to replace sucrose of the banana porridge. Therefore, the purpose of this study was to determine porridge effects on glucose, triglyceride, serum cholesterol and digesta profile in diabetic STZ-NA induced rats. Twenty-five male Wistar rats were divided into five groups and fed four different diets including the standard (KS and KN), banana porridge with sweetener IMO (BP+IMO), fibercreme (BP+FC) and (BP + Sukrosa). In these diets, porridge subtituted 30% energy of the standard diet, and the intervention was conducted for 28 days. It was found that banana-IMO porridge showed the lowest decrease in serum glucose level with 56.09%, followed by banana-fibercreme (47.61%) and bananasucrose (36.61%). Furthermore, similar trend was found in their cholesterol-lowering effects with 36.82%, 25.68% and 7.86% respectively. However, triglyceride level effects were highest in banana-IMO porridge (9.06%), followed by banana-sucrose (6.47%) and banana-fibercreme (3.72%). In addition, sucrose replacement with IMO increases weight and water content, as well as decrease caecal digesta pH. However, fibercreme increases only water content and does not decrease caecal digesta pH.

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.

High hulling process decreases the nutritional value and rice quality including milled rice because the macronutrient contained in the aleurone is wasted. Therefore, this study aims to ascertain the effects of hulling level on the quality and characteristics of red rice, black rice, and white rice, which would help produce high quality milled rice. Linear regression method was used, and the contents analysed were moisture, fat, ash, carbohydrate, anthocyanin, quality, rendemen, starch digestibility, and color. The results showed hulling would affect the proximate content and physical characteristics of milled rice. Also, low hulling of black rice produced the highest physical score, with high anthocyanin, and low starch digestibility which was good for diabetic consumers.

This study aimed to develop an instant cream soup formula composed of yellow sweet potato and red kidney bean for maternal chronic energy deficiency. The selected formula is acceptable based on organoleptic test. In addition, the food formula is expected to meet nutritional needs, including protein, fat, carbohydrate, energy, and vitamin A. Amino acid score and in vitro protein digestibility were also measured to verify whether or not the product of the formulation has high protein quality. The instant cream soup was composed of yellow sweet potato and red kidney bean. Additional ingredients that were added to increase the nutritional value and sensoryattributes of the instant cream soup included soy protein isolate, egg white flour, maltodextrin, red palm oil, onion, garlic, leek, celery, chicken broth, fresh cream (cooking cream), black pepper, and salt). This experimental study used a randomized factorial design in laboratory. The treatment unit included two factors: provision of yellow sweet potato and red kidney bean consisting of three levels (50%:50%, 75%:25%, and 25%:75%) and addition of maltodextrin consisting of two levels (0% and 5%). Hedonic organoleptic analysis showed that theselected formula comprised 75%:25% yellow sweet potato and red kidney bean and 5% maltodextrin addition (F5). Nutrient content analysis revealed that the product contained 3.85% moisture, 3.15% ash, 30.19% protein, 14.18% fat, 48.63% carbohydrate, 443 kcal energy, 17.67% dietary fiber, 87 ppm β-carotene, and 77.21% protein digestibility. This study also showed that methionine and cysteine were the limiting amino acids in the selected product with a score of 47%. Acceptability from 100 pregnant women was assessed, and results showed that 87% of pregnant women accepted the product. These results indicate that this product has the potential to be an alternative snack for maternal chronic energy deficiency because of its nutritional values.

Growol is a staple food made from processed cassava through fermentation, washing, pressing, and chopping. It is beneficial to health due to its lactic acid bacteria content. The problem was that producers always mix different cassava varieties, and varied fermentation time. Meanwhile, each cassava has different composition, especially their starch content. The fermentation time was not constant which ranges between 2-4 days. Furthermore, the typical sour taste and lactic acid bacteria content are determined by the length of this period. Therefore, this study aimed to evaluate the effect of cassava varieties and fermentation time on the chemical properties, total lactic acid bacteria (LAB), and the preference level of growol. The cassava used in this study were Meni, Ketan, and Lanting varieties, with fermentation time ranging between 2-4 days. Each sample were analyzed to determine moisture content, starch, and amylose. Furthermore, the fermented cassava that has been washed and pressed, was steamed for 15 minutes. Therefore, the resulted growols were analyzed to determine their moisture content, pH, titratable acidity, total LAB, and preference level using hedonic test method. The results showed the starch content were not significantly different, but the chemical properties was affected by the fermentation time (moisture content, amylose, titratable acidity), total LAB and preference level. Furthermore, the acceptable growols were made from Meni variety with fermentation time ranging between 2-4 days, or Ketan and Lanting varieties with 2 days fermentation. However, based on the lactic acid bacteria content, growol should be made with Meni variety with 4 days fermentation process, which had moisture content of 60.31 ± 0.21%, titratable acidity of 0.40 ± 0.05% and lactic acid bacteria content of 1.5x106 cfu/g.

The Antirogo River is a tributary of Bedadung Watershed which flows from Tegal Gede Village to Sumbersari Village, Jember Regency, East Java. The land areas near the River is used for agriculture, residential settlements, and industry. The wastes dumped from these lands degrades the water quality. Therefore, this study aimed to determine the river capacity against pollution loads, using the Streeter Phelps method in accordance with the Decree of Environment State Minister No. 110 of 2003. Water samples was taken from the River and divided into four monitoring points namely ATR01, ATR02, ATR03, and ATR04. A purposive sampling method was used and the water quality was analyzed. The average pollution load is 70.37 kg/day. Furthermore, the highest load is 81.04kg/day at ATR03 and the lowest is 64.81 kg/day at ATR04. Therefore, the river’s capacity can be determined by calculating the reaeration and deoxygenation rate, critical oxygen deficit, distance, and time taken to reach a point. The average deoxygenation rate is 1.77 mg/L.day, and that of reaeration is 16.13 mg/L.day. Also, the DOact values at ATR01, ATR02, ATR03, and ATR04 were 6.59 mg/L, 6.67 mg/L, 6.63 mg/L, and 6.67 mg/L respectively. The average value of oxygen deficit is 1.19 mg/L. According to the values of deoxygenation, reaeration, oxygen deficit, and DOact, it can be interpreted that the river is not in a critical condition, and, therefore, can tolerate pollutant load of 7.26 kg/day.
