Abstract
Gembili is one variety of local tubers originating in Indonesia, where its utilization is not in its most use. This tuber has bioactive compounds such as dioscorin, diosgenin, inulin and water-soluble polysaccharides that function as immunomodulators, including those which prevents metabolic diseases such as hyperglycaemia. The addition of gembili tubers in fermented milk has more value and is an alternative nutraceutical food for people who need a healthy diet because it contains probiotics and bioactive components. This study aims to determine the antihyperglycemic activity of fermented milk enriched with gembili flour in animal models. Probiotics contained in fermented milk are Lactobacillus acidophilus, Lactobacillus plantarum and Streptococcus thermophilus. The experimental animals used in this study are healthy male white rats, not deformed, and had never been used in previous experiments. The animals in experiment were grouped into five treatment groups namely P1= negative control, P2= positive control, P3= 1 ml/rat/day of fermented milk with the addition of gembili tubers, P4= 2 ml/rat/day of fermented milk with the addition of gembili tubers, and P5= 3 ml/rat/day of fermented milk with the addition of gembili tubers (P5). The results of this study prove that the addition of fermented milk enriched with gembili showed significant results (p<0.05) on the decrease in blood sugar levels with the highest decrease of 43.59% in the P5 group.

Abstract
Pumpkin is abundantly available in Indonesia and well known to contain high dietary fiber, β-carotene and phenolic compounds. The objective of this study was to evaluate the effect of pumpkin flour enrichment to the antioxidant activity and total phenolic content of bread. Breads were made by partially replacing of wheat flour with pumpkin flour at the level of 5% to 20%. The results showed that pumpkin flour significantly (P<0.05) enhanced antioxidant activity of enriched bread measured by DPPH and ABTS. The highest antioxidant activity was observed in bread with enrichment of 20% of pumpkin flour. At highest values, antioxidant activity were 76,59% (DPPH) and 81,74% (ABTS). Total phenolic contents of enriched bread were also significantly affected by increased level of pumpkin flour. The highest total phenolic content (5,39 mg GAE/g) was observed in bread with enrichment of 20% pumpkin flour compared to that of control bread (1,38 mg GAE/g). Thus, we concluded that pumpkin flour can be employed to enhanced antioxidant activity and total phenolic content in bread.

Abstract
Oligosaccharides are a group of sugar polymers with degree of polymerisation of 2 to 10 monosaccharides linked by glycosidic bonds. Oligosaccharides are grouped according to their monomer components and linkages; fructooligosaccharides, maltooligosaccharides, xylooligosaccharides, galactooligosaccharides and etc. Plant oligosaccharides are found naturally in some fruits and vegetables but certain oligosaccharides such as xylooligosaccharides can be industrially manufactured from agricultural byproducts. Oligosaccharides that cannot be digested by human digestive system but selectively fermented in the colon had been proven to be a prebiotic ingredient. The addition of prebiotic oligosaccharides to food enhances functional properties beneficial for the body including bowel function, calcium absorption and lipid metabolism, prevention of dental caries, protection against cardiovascular disease and decrease in the risk of colon cancer due to the formation of short-chain fatty acids. The global xylooligosaccharides market is valued at 88.09 million USD in 2016 and is expected to reach 119.62 million USD by the end of 2022. Due to global demand of xylooligosaccharides and availability of agricultural byproducts from oil palm plantation and palm oil industry, Malaysia and Indonesia should play important role as manufacturers of xylooligosaccharides.

Abstract
Melon is one of high demands fruit in Indonesia, but the research about the fruit coating to fresh melon is still rare. This research is about application of fruit coating (chitosan) in different harvesting times to keep the quality and shelf-life of melon in room storage. The study was aimed to study the effect of chitosan and harvesting time on fruit quality and shelf-life melon in normal room storage. The research was conducted using a completely randomized design in two factors. The first consisted of 2 treatments; without coating (control) and with the coating (chitosan). The second consisted of 3 treatments of harvesting time; 60, 65, and 70 days after planting. Each treatment is repeated 4 times. The data is then analyzed in variance with F-test, then proceeded with the separation of the middle value with LSD at the 5% level. The results showed that fruits shelf-life can be extended until 20 days storage based on visual observation, but for fruits that were applied chitosan and harvested on 60 and 70 days can be extended 10 days and 15 days only. Application of chitosan didn-t significantly affect the quality of the melon such as on weight loss, soluble solids, and level of preferences (color, sweetness, texture, and aroma), but as additional information the level of preferences test showed that fruits applied with chitosan which were harvested on 65 and 70 days after planting experienced off-flavor on the 5th days of storage.

Abstract
This study aimed to investigate the quality characteristics of rice bread containing Helianthus tuberosus powder that shows excellent physiological functions, and the effect of its intake on blood glucose. Five samples were tested, H. tuberosus powder 5% (HRB1), 10% (HRB2), 15% (HRB3), 20% (HRB4) and control. HRB2 had the highest specific volume. The moisture content of rice bread tended to increase as the concentration of H. tuberosus powder increased. The L value and crumb colour value tended to decrease significantly with an increasing amount of H. tuberosus powder, whereas the b value was increased significantly. Hardness was the lowest in HRB2 and HRB3. In sensory evaluation, there was no significant difference in the appearance among the four groups. HRB1 had the highest values for flavour, texture, and overall evaluation. Taste showed no significant difference until HRB1. Rice bread samples with 15% HRB were selected to measure the hypoglycaemic effect of H. tuberosus compared to that of control rice bread (RB) and wheat bread (WB). The results showed significantly different blood glucose levels (p < 0.05) among treatments. Calculation of the glycaemic index (GI) showed HRB to have the lowest GI. As a result, rice bread containing H. tuberosus powder is expected to increase insulin sensitivity in diabetes.

Abstract
The common process of making copra is by drying under sunlight or fumigating by utilizing biomass (coconut shell). The disadvantages of this method of drying and fumigation are that processing time lasts for 5-7 days and it is very dependent on weather conditions. In addition copra quality was often unstable, moldy and moisture content is not suitable therefore cannot fulfill requirements as white copra. Selayar regency has known as a copra producing center in South Sulawesi, therefore it becomes one of the considerations of choosing community creativity program (PKM) partners from this region. The goal to be achieved is the process of transferring technology to partners so that motivate other coconut farmers who will eventually be able to increase their income. The output of this activity is the result of a white copra drying oven. The program implementation phase begins with the design of the drying oven at the Politeknik Negeri Ujung Pandang (PNUP) mechanical workshop followed by demonstration of equipment usage at the partner location and the final stage of the activity is the delivery of the equipment to the partners From the result of testing equipment, the quality obtained was 10.14% moisture content, 54.15 oil content and 0.05% free fatty acid level for 25 hours drying time. This result has met the C Grade of SNI standard.

Jember district was chosen as the location of this research, because from the previous survey information showed that Jember district had a rice field area used a technical irrigation system so those field can applied a cropping pattern model within one year with rice plants and other food crops such as corn, and soybeans. Besides, farmers are accustomed to raising cattle, especially beef cattle as additional activities besides crop farming. This research conducted from November 2016 to April 2017. Sustainability Analysis with MDS Rap-Sispotta as the data Analysis of this research. Based on the five existing dimensions, the results showed that the agribusiness integration system of cattle and crops in this research area has a sustainability index value of 42.40. This index showed that agribusiness is still less sustainable. The dimensions that have the worst sustainability index and need to be taken seriously at are technology and infrastructure dimensions, also law and institutional dimensions.

Abstract
Politeknik Negeri Jember (POLIJE) is the leading vocational institutions that promote applied research as a form of downstream to solved the problems of stakeholders (both industry and society). The indicator of the vocational college-performance is the number of innovations that have been implemented in the industry and society. One of the problems found in the SME community partners primarily in the food industry, especially in the tempeh processing industry. Making tempeh with local raw materials and traditional methods requires a lot of water and the product also decays quickly. POLIJE team, Wibisono; Santoso and Budiati initiated industrial tempeh in Al Islah Jenggawah Jember for using local soybean. Training and coaching activities is funded by the Indonesian Ministry of Research, Technology and Higher Education through PKM Programs (Community Partnership Program). In the event, POLIJE team giving equipment to the process of making modern tempeh, such as an incubator for the production of special ragi (yeast) equipped with gear sensor (sensor cable thermometer, TDS tester and others); soybean washing machine; soybeans peeler (for the development of turnover) as well as digital microwave for preparation of media for yeast. In the treatment process before the community service is to get local tempe with the highest levels of genistein. As for the treatment factor is the type of yeast which includes raprima (factory made) yeast with artificial yeast based on the Wibisono method. The duration of fermentation uses a time duration of 0; 6; 12; 18 and 24 hours. Each time fermentation has been determined, genistein (and genistin) is tested. The research results above indicate that optimal hydrolysis of genistin is carried out at 43 oC for 18 hours. PP Al Islah recognize that using washers soybeans, can save up to 30 minutes each 100 kg of material and no raw material is wasted, and it can save water usage so that will be able to reduce water tempeh industrial waste products. The results showed no difference in the value of TSS (Total Suspended Solid) between manual washing compared with modern equipment, Also results of research studies the content of genistein showed increased by 33% compared to conventional methods.

Abstract
Dietary fiber intake provides many health benefits. Individuals with low intakes of dietary fiber appear to be at significantly higher risk for stroke, obesity, diabetes,hypertension, certain gastrointestinal diseases, and coronary heart disease. Functional drink with higher fiber is expected to increase fiber intake in society. The aims of the research is to investigated the charateristic of the mixture of of soybean powder and dragon fruit peel powder as functional drink. All experiment were designed in complete random. Dragon fruit peel powder and soy powder were mixed according to the treatments. The result showed that dragon fuit peel powder give higher water content, soluble, insoluble and total dietary fiber. Moreover the color functional drink from dragon fuit peel powder have darker dan red color.

Abstract
Honey is a sweet liquid produced by bees that is sourced from nectar or liquid from high contained-carbohydrate plants (sucrose, fructose, and glucose). The high carbohydrate content makes it not allowed to be consumed by Diabetes Mellitus (DM) patients. This research aimed to obtain one of the biological values of honey which is Glycemic Index (GI). The result of this research is expected to be reference for the amount of honey that is allowed in one-time consumption especially for people with DM. The type of honey used in this research are from West Kalimantan, namely Tikung and Kelulut. Tikung honey is obtained from a nest called tikung which made from rambesu wood. This honey is widely available in Kapuas Hulu Regency. Kelulut honey is from Trigona sp. cultivation, and widely cultivate in Mempawah Regency. This research is conducted at the laboratory of Agricultural Product Technology (THP) of Agriculture Faculty, Tanjungpura University in collaboration with the Sungai Raya Community as medical personnel in GI measurement. The measurement was taken by in vivo method using 12 healthy respondents. The result shows that glycemic index for tikung honey is 35 (low) and kelulut is 39 (low). Recommendation for maximum honey consumption in one-time based on glycemic load values (low category) is 20g or one tablespoon (for kelulut honey) and 40g or two tablespoon (for tikung honey). This research is expected to be one of the references in honey consumption for both healthy people and DM patients.
