: Research about the abundance and length-weight relationship of anchovy pekto ( Stolephorus waitei ) has been carried out in Tanjung Beringin Water, Serdang Bedagai Regency, Sumatera Utara. This study aims to analyze the abundance, distribution pattern, and length-weight relationship of anchovy pekto. This research use purposive sampling methods. Sampling of anchovy pecto use a mini purse seine. Abundance and distribution of anchovies were analyzed using the equation according to [1] and the length-weight relationship using the Fish Stock Assessment Tool version 2. This study obtained 1238 ind/60 m 2 . The highest abundance of anchovy at station 1 is 490 ind/60m 2 , followed by station 2 is 386 ind/60m 2 , and the lowest at station 3 is 362 ind/60m 2 . The distribution pattern of anchovy pecto is group distribution. The length-weight relationship of anchovy pekto showed that increase in anchovy body weight faster than its length, which illustrates a positive allometric growth pattern, with a value of b > 3.

: Robust reliable performance metrics enable a management to identify and address deficiencies and control factors to improve performance of any system. The complexity of modern operating environments presents real challenges to developing equitable and accurate performance metrics. This paper presents literature review and analysis of how mathematical methods utilized and functioned to develop a control factor or dynamic constraint in endeavoring to increase environmental performance of eco-industrial parks. Constrained minimax optimization model is developed to maximize economic gain while minimizing waste in a region within the border where dynamic carrying capacity is maintained stable. Carrying capacity is added in as control factor to increase environmental performance within a boundary or area within which balance of carrying capacity is maintained, in order to increase environmental performance without reducing quality of environment.

: Dextrin-citric acid adhesive is predicted to be a promising natural adhesive of particleboard. Different types of dextrin may affect the performance of wood bonding. The aim of this research was to investigate the effect of dextrin types and the ratio of dextrin/citric acid on the physical and mechanical properties of particleboard made of petung bamboo ( Dendrocalamus asper ). Two kinds of dextrin-based materials, i.e. maltodextrin and durian seed dextrin were applied in this research. The dextrin/citric acid ratios were set at 100/0, 75/25, and 50/50 wt%. The particleboards were made in 25 cm x 25 cm x 1 cm size, with target density and adhesive content were set at 0.75 g/cm³ and 15 wt% based on the dried weight of particles, respectively. A three-step press cycle method was used for particle board manufacturing and the press condition was set at 200°C for 10 minutes. The result showed that particleboard with maltodextrin-based adhesive has better properties than particleboard with durian seed dextrin-based adhesive. The best properties of particleboard were achieved by maltodextrin/citric acid adhesive at the ratio of 50/50 wt%. Those properties could meet the requirement of Japanese Industrial Standard (JIS) A 5908 (2003) for particleboard. In addition, this research indicated that durian seed dextrin can be improved as adhesive for particleboard.
糊精-柠檬酸胶粘剂是一种很有前途的天然刨花板胶粘剂。不同类型的糊精会影响木材粘合的性能。研究了糊精种类和糊精/柠檬酸配比对竹材刨花板物理力学性能的影响。本研究采用了麦芽糖糊精和榴莲籽糊精两种糊精基材料。糊精/柠檬酸的比例分别为100/0、75/25和50/50 wt%。刨花板尺寸为25 cm x 25 cm x 1 cm，目标密度和粘合剂含量根据颗粒干燥重量分别设定为0.75 g/cm³和15 wt%。采用三步压循环法制作刨花板，压条件为200℃，压10分钟。结果表明，麦芽糊精基胶粘剂对刨花板的性能优于榴莲籽糊精基胶粘剂对刨花板的性能。麦芽糖糊精/柠檬酸胶粘剂在50/50 wt%的比例下可获得最佳的刨花板性能。这些性能符合日本工业标准(JIS) A 5908(2003)对刨花板的要求。此外，本研究还表明，榴莲籽糊精可以作为刨花板粘合剂进行改进。

: Research on the effect of sisal fiber angle on density, water absorption, porosity, flexural strength, impact strength, and tensile strength of sisal-epoxy resin composite fibers. Composites are made by hand lay out method in the composition of sisal fiber material: epoxy resin = 10 wt% : 90 wt% with the fiber angle orientation layout at: 0°, 30°, 45°, 60°, 90°. Composite properties obtained have an average density of 1.2 g/cm 3 , water absorption increases linearly, and porosity of composites rises linearly to changes in angle increment which is greater and has flexural strength, impact strength, composite tensile strength linearly decreases to changes in the incremental angle. Optimal mechanical properties occur at the angle of fiber 0°, this is due to the long fiber direction, in the direction of the tensile force which is at 0°. The length of each fiber at 30°, 45°, 60°, 90°, will have lower mechanical properties, due to the shorter load distribution.

: Lignin residual liquid is a macromolecule compounds resulted from the delignification process of empty bunches of palm oil within alkaline condition. This study reports the potential results of lignin residual liquid as the precursor of fluorescence carbon nano-particles synthesized from heating treatments. The characteristics of samples were tested by using FTIR, Spectrophotometry UV-Vis, and UV-lights observation. The results showed that FTIR spectra confirmed the functional groups of hydroxyl, while the visible spectrum displayed none absorbance. The UV spectrum displayed varied peaks from 214 to 319 nm which indicated different absorbance features within highly alkaline condition, whereas green-neon colour was shown under the UV-lights. This implies that various fluorescence properties occur from this study.

: Superconductor samples based on BPSCCO-2223 have been prepared using solid state reaction. Precursor material (powder): Bi 2 O 3 , PbO 2 , SrCO 3 , CaCO 3 and CuO were mixed together using agate mortar for 2 h with twice grindings. Powder were then sintered at 300°C for 6 h with a rate of 10°C/min and 820°C for 20 hours at the same rate. MgO powder was added for 5%wt and 15%wt, respectively. The same amount as well as same procedure was applied for Na 2 CO 3 powder addition. The powder was then put into palletising machine with 250 MPa before sintering at 850°C for 30 hours. Effect of addition Na and Mg on crystallite size and phase formation had been observed using XRD (powder method) type PAN analytical Empyrean. XRD-pattern was analysed with aid of Match v1.10 software. Results showed that crystallite size increased for 9.5% by addition of 5%wt Mg but decreased for 13.6% with 15%wt Mg. Addition of 5%wt Na decreased the crystallite size for 31.8%, whereas 15%wt Na decreased it to 14.2%. Maximum volume fraction of Bi-2223 (65.18%) was observed in non-doped sample.

: Bioethanol is a liquid produced from the sugar fermentation process from carbohydrate sources by using the microorganism. In present study, Saba banana hump (Musa paradisiacal. L) sample was isolated by precipitating the starch with water for 12 hours. Furthermore, the starch was hydrolyzed using HCl 25%, and 14.01% of glucose solution was obtained. The starch obtained was tested using Fourier-transform infrared spectroscopy. Then the sample was fermented using Zymomonas mobilis microorganism immobilized by Ca-Alginate 4% with variation of inoculums 5%, 10%, 15% (v/v). Bioethanol from fermentation process was tested using gas chromatography (GC). The highest bioethanol content is 79.01% and the highest productivity that obtain was 2.66 g/L.Hours.
