Nypa is a mangrove plant that acts as a food source, such as nata. Research has shown that nipah plant waste, such as frond fibers and nipah fruit skin fibers, can be used as a raw material in making nata fruticans. The purpose of this study was to determine the potential of nipah fiber (Nypa fruticans Wurmb.) in nata production using soybean sprouts as a nitrogen source. The samples of nipah fiber (Nypa fruticans) used were leaves (DN), midrib (PN) and fruit skin (KB), taken in the Kuala Tungkal area, West Tanjung Jabung Regency, Jambi Province. This research method includes making the mother solution, making nata starter, and producing nata sheet by using soybean as a source of nitrogen with a concentration of 5%, 10% and 15% and ZA as a control. The results of this study indicate that the best volume and thickness of nata fruticans can be seen from the midrib substrate with a concentration of 10% soybean sprouts. The yields produced for all treatments were still lower compared to controls. Meanwhile, the water content of all treatments was better than the control. The best quality of Nata Fruticans based on thickness, yield and average moisture content was generally obtained from the substrate from the leaf midrib fibers with a concentration of 10% soybean sprouts

Dragon fruit skin, waste material (dragon fruit waste), will have a profitable sale value if it can be used as a food raw material. Dragon fruit skin waste contains relatively high dietary fiber so it can be used as a food raw material. This study aims to utilize dragon fruit skin waste for the manufacture of dragon fruit skin flour as an alternative food source. Some tests are made on white-meat dragon fruit skin, red-meat dragon fruit skin and super red dragon fruit skin. The preliminary study is the soaking of the three types of dragon fruit skin in two solutions, namely 0.1% sodium citrate and 0.1% sodium metabisulfite to prevent the browning effect on flour. Dragon fruit skin flour from the soaking with both solutions is then characterized physically, including its texture, color, flavor and rendement. The best physical characterization is followed by chemical characterization, including the contents of water, ash, protein, fat, carbohydrate, dietary fiber, minerals (Fe, Na, K, Ca and P), and also microbiological characterization of Escherichia coli, molds and Bacillus cereus. The chemical and microbiological characterization shows that the red-meat dragon fruit skin flour has better results than the white-meat and super red dragon fruit skin flour does. The red-meat dragon fruit skin flour contains 8.80% water, 0.20% ash, 2.35% fat, 7.69%, protein, 68,29% carbohydrate and 28,72% dietary fiber as well as 4.40 mg K, 8.76 mg Na , 0.65 mg Fe , 10.20 mg Ca and 32.58 mg P.

Research on the rectangle packing problems has mainly focused on rectangular raw material sheets without defects, while natural slate has irregular and defective characteristics, and the existing packing method adopts manual packing, which wastes material and is inefficient. In this work, we propose an effective packing optimization method for nature slate; to the best of our knowledge, this is the first attempt to solve the guillotine packing problem of rectangular items in a single irregular and defective slate. This method is modeled by the permutation model, uses the horizontal level (HL) heuristic proposed in this paper to obtain feasible solutions, and then applies the genetic algorithm to optimize the quality of solutions further. The HL heuristic is constructed on the basis of computational geometry and level packing. This heuristic aims to divide the irregular plate into multiple subplates horizontally, calculates the movable positions of the rectangle in the subplates, determines whether or not the rectangle can be packed in the movable positions through computational geometry, and fills the scraps appropriately. Theoretical analysis confirms that the rectangles obtained through the HL heuristic are inside the plate and do not overlap with the defects. In addition, the packed rectangles do not overlap each other and satisfy the guillotine constraint. Accordingly, the packing problem can be solved. Experiments on irregular slates with defects show that the slate utilization through our method is between 89% and 95%. This result is better than manual packing and can satisfy actual production requirements.

Organical material such as animal dung, husk ash, bran, and sawdust is often used  in bocation production. In this study, the paper waste of printing company at Syiah Kuala University was enriched in the raw material of bocation production. This study was aimed to determine the proportion of paper waste that can be added and the duration of fermentation process in order to produce a good bocation. The method used was a factorial Completely Randomized Design (CRD) which consisting of 2 factors. The first factor was the proportion of paper waste (K) with  4 levels: K1 = 15%, K2 = 25%, K3 = 35%, and K4 = 45%. The second factor was the fermentation duration (L) with 3 levels: L1 = 0 day, L2 = 10 days, and L3 = 15 days. Each treatment was repeated twice so that there were 24 experimental units. The analysis included: water content, total microorganisms, temperature, pH, C element, N element, C/N ratio, organoleptic (texture, aroma, color) and plant growth test. The result showed that additional paper waste with a proportion of up to 35% generally has a positive effect on the quality of the location in terms of water content, pH, nitrogen, texture, aroma, color, and plant growth. The longer the fermentation took place (up to 15 days) the better was the quality of the bocation produced, especially regarding C element, N element, C/N ratio, texture, aroma, color and plant growth. There were 3 interactions with the best plant height namely K3L3 (112.5cm), K3L2 (104 cm) and K2L3 (104 cm). The K3L3 bocation (35% paper waste proportion, 15 days fermentation) was better than the other two interactions in term of highest water content, N, and color value, and the lowest C/N ratio.
