The policy to prohibit cantrang fishing gear is intended to prevent excessive exploitation of fish resources, environmental degradation and conflicts between fisherman, but fisherman and government officers’ perceptions of the policy are not the same. The purpose of this study was to analyze the perceptions of fisherman and government officer on the implementation of the prohibition of cantrang fishing gear policy in Lampung Bay. Data collection was carried out by interviewing 30 fishermen and 30 government officers. The data obtained were analyzed using a Likert Scale and polarized between the perceptions of fisherman and government officers. The results showed that fisherman’s perceptions of the successful implementation of cantrang fishing gear prohibition policies were influenced by the attitude of the implementers and the inaccurate standards and policy targets/policy size and objectives. This is following the fisherman’s refusal to prohibit cantrang fishing gear policy by continuing to operationalize cantrang fishing gear. The perception of the government apparatus the high influence of the economic, social and political environment influences the successful implementation of cantrang fishing gear prohibition policies. Perceptions between fisherman and government officers who are not in harmony cause the failure of the cantrang fishing gear prohibition policy in Lampung Bay. Thus it is necessary to review the policy of prohibiting fishing gear cantrang and strategic steps for its implementation.

Production of biogas from coffee pulp waste is one of the potential attempts to provide alternative energy in Indonesia. As a leading commodity in Indonesia, the coffee produced the residual waste from its processing such as the pulp waste (include the exocarp, mesocarp, and endocarp). The waste contains the toxic agent such as caffeine, tannin, and free phenols which can inhibit the biogas production. Therefore, in this study, the biological pretreatment using civet feces ( Paradoxurus hermaphroditus ) was performed. The performance and kinetic of biogas formation from the coffee pulp (with and without pretreatment) using cow dung and a mixture of rumen fluid and cow dung as inoculum have been investigated. Biogas production was done anaerobically for 40 days at mesophilic temperature (37 o C) in a reactor with a working volume of 3.6 liters. Measured parameters included the inhibitor components, TS, VS, COD, production of biogas, and kinetic parameters. This study reveals that the pretreatment using civet feces could reduce the inhibitor compounds in the coffee pulp waste leading to produce methane in higher concentration than those without pretreatment. The digester containing pretreated coffee pulp with cow dung and rumen fluid addition showed the best performance of biogas formation. Kinetic parameters which were obtained from the fourth digester were k (0.0446 day -1 ), Y (0.056 g cells/g substrate), μ m (0.0688 day -1 ), K s (25.2359 g/L), and y m (43.299).
从咖啡浆废料中生产沼气是印度尼西亚提供替代能源的潜在尝试之一。作为印度尼西亚的主要商品，咖啡在加工过程中产生的残余废物，如纸浆废物(包括外果皮、中果皮和内果皮)。废水中含有咖啡因、单宁、游离酚等有毒物质，可抑制沼气的产生。因此，本研究采用果子狸粪便进行生物预处理。研究了以牛粪和瘤胃液-牛粪混合液为接种剂，对咖啡浆(经过预处理和未经过预处理)产气的性能和动力学。在一个工作容积为3.6升的反应器中，在37℃的中温条件下厌氧生产了40天的沼气。测定的参数包括抑制剂组分、TS、VS、COD、产气量、动力学参数等。本研究表明，果子狸粪预处理可以减少咖啡浆废弃物中抑制剂的含量，从而产生浓度高于未预处理的甲烷。添加预处理咖啡浆、牛粪和瘤胃液的沼气池产气效果最佳。动力学参数为k (0.0446 d -1)、Y (0.056 g细胞/g底物)、μ m (0.0688 d -1)、k s (25.2359 g/L)和Y m(43.299)。

As one of the marine resources, macroalgae presumably contains of free amino acid such as taurine. Taurine is known to be one of the most important amino acid related to hyperosmotic stress for most of living organisms. The study was conducted to explore the taurine contain from the most abundance macroalgae found in Indonesia seawater, especially in Lampung Province, namely Halimeda opuntia L., Sargassum sp. and Eucheuma cottonii L. Maceration followed by ethanol extraction was applied to those three different macroalgae and the filtrate was identified for its taurine content by using UV-Vis spectrophotometry. Standard of pure taurine of 0,1 and 1 M (NOW) was used and the maximum wavelength of under the UV-Vis spectrophotometry was 630 nm. Simple correlation from the standard taurine was y = 0.001x+0.033 and used to determine the taurine content of those three macroalgae. The result indicated that potential taurine content of Halimeda opuntia L was 7.85 mg/100g dry mass, Sargassum sp was 1.21 mg/100g dry mass and Eucheuma cottonii L was 4.61 mg/100g dry mass.

This research aimed to examine the effect of cellulose microfibrils (CMF) as a filler to thermal characteristics and morphology of bioplastic. Sorghum starch and chitosan, of which 63 micron particle size, were varied by starch to chitosan ratio (g/g) of 10:0; 9.5:0.5; 8.5:1.5; 7.5:2.5; 6,5:3.5; and 5.5:4.5 respectively. About 1 gr (10% on a weight basis) of glycerol, as a plasticizer, was appended to the mixture. The addition of CMF was done to the mixture, and its concentration was varied 0, 1, 2, and 3% (w/w). The combination of 8.5 g sorghum starch and 1.5 g chitosan gave the best results. It revealed the enhance of the thermal characteristic of bioplastic due to the increase of the filler — this phenomenon expressed by glass transition, crystallinity, and melting temperature of bioplastic. The SEM analysis on the morphology structure of the bioplastic surface showed that the addition of the filler will contribute to dense of bioplastic structure.
