Abstract

Aquaponic is considered one of alternative culture system to improve production and quality of leafy vegetables by combining soil less culture and fish farming. Utilization of fish manure contained in waste water provides nutrient sources for growing plants. Three kinds of leafy vegetables including water spinach (Ipomoea aquatica F.), green coral lettuce (Lactuca sativa L.), and bok choi (Brassica rapa L.) were grown using both aquaponic and hydroponic system at the Green House in Serut village, Panti District, Jember Regency, from April to June 2019. Productions of each leafy vegetable were evaluated on both culture systems. Water spinach represented 29.12% higher production in aquaponic than hydroponic system, shown by significant value in plant height, number of leaves, root volume, and leaf fresh weight. Otherwise, bok choi production displayed 17.03% increased in hydroponic than aquaponic system. However, leaf production of lettuce was not significant between hydroponic and aquaponic system. Lettuce production in aquaponic only 1.90% lowest than hydroponic system indicated that lettuce was appropriate to cultivate in both farming systems. Keywords: aquaculture, Brassica rapa L., leaf fresh weight, Ipomoea aquatica F., Lactuca sativa L., soil less culture

Abstract

Processing cassava into various food products is an effort to produce the economic added value of cassava. The processing also needed to reduce the damage of fresh cassava. This study was aimed to asses the performance of ‘kelanting’ as an indigenous snack and its added value. Data were collected at the Plamboyan Farmer Women's Small Group (KWT) in Rejomulyo Village, Palas Subdistrict, South Lampung Regency from August 2019 to November 2019 using questionnaire. The descriptive analysis used to describe the industry performance, while the added value calculated quantitatively using Hayami Table. The results showed that the performance of the processing of cassava by the Plamboyan Small Women Farmers Group (KWT) was affected by the high availability of raw materials, i.e. ‘mentega’ cassava as local variety and how to process ‘kelanting’. The added value of processing cassava become ‘kelanting’ was Rp 5,493.00/kg with a value-added ratio of 64.55% which was classified as high value-added (>40%). The profit was Rp. 3,743.00/kg with profit rate of 68.14%. Keywords: added value, cassava, processed cassava product

Abstract

As an authentic food of Palembang people in South Sumatera Province, pempek is famous local food caused of unique color (yellowish-white color), flavor (fishy flavor), and chewy texture. Pempek as semi-wet food that can be dried to decrease water content and increase the shelf life. Dried pempek has a lighter and smaller volume material and making it easier to distribute and expand marketing. Pempek can be prepared from ground fish (cork fish), tapioca flour, salt, and water. These ingredients are mixed to form a dough. Pempek dough can be formed into a small pempek, such as lenjer, pastel, otak-otak, adaan, keriting, and kapal selam. Pempek is generally has a wet form. Wet pempek has a high water content of 50-60%, so it had shelf life about 3-4 days. Therefore, wet pempek must be dried to make it long shelf life. The aim of the research was to know about small dried pempek lenjer characteristic based on various addition of CaCl2. The treatment of various CaCl2 concentrations has a very significant effect on water content and protein content (chemical value) and significantly influence the organoleptic properties (aroma, color, and taste) of the dried pempek lenjer. The 1.5% concentration of CaCl2 (C3) treatment has the highest average level of likeness on aroma 3.75, color 3.90, and taste 3.95 with preferred criteria on a dried pempek lenjer. Keywords: chemical, organoleptic, small dried pempek lenjer

Abstract

Phytases are enzymes that sequentially remove phosphate groups from myo-inositol 1,2,3,4,5,6-hexakisphosphate (phytate), and are the main storage form of phosphate in plants. It has been produced an extracellular phytase from a wild type Aspergillus niger in a submerged culture. The phytase was purified in two steps by using ammonium sulphate precipitation (0-50% and 50-80% saturation) and DEAE-Cellulose column chromatography. Under these experimental condition, the phytase could be purified at 30 folds. The enzyme showed a maximum catalytic value at pH 5.0 and optimum temperature at 600C. Based on a lineweaver-Burk equation, the purified phytase had the Km and Vmax value by 0.42 mM and 15.2 Pi hour-1 mg protein-1, respectively. The ability of the phytase to hydrolyze phytic acid in maize powder was higher than phytic acid in soybean powder. Keywords: phytase, phytic acid, Aspergillus niger

Abstract

Panti District is the second-largest coffee plantation in Jember Regency, with an area of 160.71 ????????2 or 4.88% of the total area of Jember Regency with an average height of 50-1,340 meters above sea level. With this average height, one of the coffee plants planted was Arabica coffee. Based on the number of existing coffee plantations, the processing of wet coffee produced a lot of liquid and solid waste. Coffee fruit waste in the form of flesh physical composition reached 48%, consisted of 42% fruit skin and 6% seed skin. The utilization of coffee waste is still not optimal. One effort to reduce coffee waste was by applying cleaner production. The method used to determine this priority of production application at Maju Mapan Coffee Agroindustry is AHP (Analytical Hierarchy Process) method, technical feasibility, and financial feasibility analysis. From mass balance analysis, the results showed that from 1 ton of red coffee berry and 3146.63 liters of water as production input produced 40% of coffee beans, 38.4% solid waste, and 2946 liters of wastewater. The wastewater characteristics exceeded the threshold standard of wastewater quality stipulated by the Decree of the Governor of East Java Number 45 of 2002. On the other side, solid waste most unsettled the surrounding community because every day, it created a foul odor and invited many insects. Clean production priority in Maju Mapan Agroindustry using AHP, technical feasibility, and financial feasibility analysis obtained are manufacturing the cascara tea, compost block, and animal feed. AHP analysis results using the application of expert choice assessment in an alternative hierarchy of the ten experts showed that making cascara tea was chosen as the main priority in the utilization of waste from Arabica coffee processing in Maju Mapan Agroindustry. Keywords: AHP, arabica coffee, cascara tea, cleaner production, coffee waste
