    This research would explain about Indonesia\u27s government policy to stop and banned the illegal fishing\u27s activity after Indonesia\u27s got many disadvantage in the fishery sector. This policy created a pro and contra for actors has illegal fishing\u27s activity like foreign fishing vessels and Indonesian\u27s fishing vessels.To see the problem of Indonesia\u27s Government Issuing Moratorium of Permit to Fishing Effort in the Fisheries Management Area Republic of Indonesia, the author uses a qualitative research methodology, the data collection techniques by library reseach are derived from sources of literature books, published magazine, journals, and scientific articles. The persepective used is Merchantilism that see the state\u27s role in regulating its economy. The theory used is Protectionism.Indonesia\u27s policy became implications for improved utilization of sources from the sea, improvement of fishery management, eradication of illegal fishing and an increase in achieving economic goals such as exports that are beginning to increase again. While the implications of this policy for illegal fishing\u27s actors from several countries in Indonesia\u27s around is lessening fishing effort than usual

    Maintenance is an activity to maintain or keep the facility / factory equipment and make necessary repairing or adjustment / replacement, so that there is a satisfactory state of production operations in accordance with what was planned and not damaged. Damage to the system is likely to cause serious consequences for companies such as the cost of downtime or lead to unsafe conditions due to damage to the tool. Backup equipment can be used to reduce the effects of damage to the equipment. The production process at PT. X uses quite many machines. One of the machines often has damage is Curing hoist machine that is used to move concrete products to the next process. All hoist machines have got preventive maintenance work in accordance with the instructions of the existing tools. But in reality, some sort of hoist machine still often damage. The hoist machine part are often damages is motor parts. This study aims to determine the number of motor hoist machine Curing optimal backup to anticipate delays in production with a Poisson distribution approach and consider some of the costs. Poisson distribution is a discrete probability distribution that presents frequency from a certain random event. The research resulted in the number of motor Hoist machine backup is 4 pieces at a cost of Rp 144,218.0

    Objective: Simultaneous quantification of Rosuvastatin and Fenofibrate tablets by HPTLC method was developed and validated as per International Conference on Harmonization [(ICH) Q2 (R1)] guideline. Methods: The chromatograms were developed using a mobile phase of ethyl acetate: acetic acid (20: 0.2, v/v) on aluminium pre-coated plates of silica gel G F254 of TLC plates and quantified by densitometric absorbance mode at 246 nm. Results: The Rf values were 0.31 ± 0.01 and 0.76 ± 0.01 for Rosuvastatin and Fenofibrate, respectively. The linearity of the method was found to be in the concentration range of 50-800 ng/band for both drugs. The limits of detection and quantification were 11.07 and 33.56 ng/band for Rosuvastatin and 12.76 and 38.68 ng/band for Fenofibrate. Conclusion: Developed densitometric method was found to be robust, precise, accurate, rapid and can be used to analyse fixed-dose tablet samples of Rosuvastatin and Fenofibrate

    Supplier is one of the most important part in construction service company. To get the best result, it needs the best and quality supplier. One effort to get those supplier is to perform supplier selection, therefore supplier selection is necessary for construction service company. Since many supplier, PT. Cipta Nuansa Prima Tangerang had a trouble in choosing supplier with their respective advantages. The process of supplier selection use AHP (Analytical Hierarchy Process) method, which outline the criteria into the process of comparing alternatives. The greater the value generated, then the main well for those supplier will be chosen. The criterias of supplier selection on PT. Cipta Nuansa Prima Tangerang are delivery, service, product, quality and price. The supplier selection use AHP method with tools Expert Choice and proven with Ms. Excel allow company to support the decision. AHP method is the best solution to be a Decision Support System for solving the problem and contribute management for making decision more objective of supplier selection

    Adaptive Reuse of Heritage Building and the Impact to the Visual Comfort: Assessed by the Lighting Quality

    Full text link
    Heritage buildings are designed mostly to be adaptive with the local climate. The main purpose of these adaptive strategies is to create users' thermal comfort as well as solving the problem of high rain precipitation in the tropical climate area. These thermal adaptation strategies will definitely influence room daylight condition. External shading device used in heritage building is one of thermal adaptation strategies, but it will also obstruct the daylight penetration. Design solution should be thought to maximise daylight condition. However, the design solution for heritage building has its own limitations where certain guidelines must be adhered, especially when resizing the existing windows to obtain better daylight condition is needed. This research studies the daylight condition on the designated schools and finding the most feasible solutions to overcome the lighting problems. The existing condition of the daylight was measured using lux meter and the data obtained were analysed descriptively by comparing to the related references in order to gain a maximum result. A simulation by using computer software was also conducted for simulating daylight level in both buildings. Based on the measurements that have been conducted, it shows that the daylight level on the designated buildings was below the standard and the current artificial lighting system was also failed to create the standard illuminance level The solutions for this problems are resizing the window or creating an artificial lighting system. Although in this research proposes 2 solutions to overcome the problems, the latter solution is considered as the most feasible solution to treat heritage building to be a visually comfortable building without major alteration on the building fabrics since both studied buildings are listed as a National Heritage Monument

    STUDIES ON KINETIC PARAMETERS AND BIOCHEMICAL CHARACTERISTICS OF POLYPHENOL OXIDASE PURIFIED FROM JACKFRUIT (ARTOCARPUS HETEROPHYLLUS) WASTE

    Objectives: Polyphenol oxidase activity was extensively studied in jackfruit for its role in enzymatic browning. PPO and the phenolic compound play a vital role in defensive mechanism against pest and diseases. Thus, to facilitate further studies in jack fruit waste, Polyphenol oxidase [PPO] was purified and characterized.Methods: Partial Purification of PPO from waste done through a sequential process of ammonium sulfate precipitation, dialysis and ion-exchange chromatography [DEAE- Cellulose]. Then the partially purified PPO was subjected to check various parameters like molecular weight and kinetic activity, the following characteristics of enzyme are checked: SDS-PAGE, pH, temperature, thermal stability, heat inactivation, metal ions, surfactants and inhibitor.Results: Purified PPO resulted in ~23 folds enriched in the specific activity of 1360 [µkat/mg] and it was found to be the monomer with a molecular weight of 63 kDa revealed by Coomasie Brilliant Blue staining. PPO exhibited optimum activity at pH 7.0 and temperature 20oC. PPO showed the maximum stability between pH 6.4- 7.6 at 10 oC - 40 oC. PPO showed the enzyme activity towards Diphenol> Triphenol> Monophenol, the substrate specificity was especially high towards the catechol at 0.1 M. The PPO activity was activated by Mn2+, Triton X- 100, EDTA, Sorbic acid and Citric acid, but inhibited by L- cysteine, Ascorbic acid, SDS, Cetyl trimethyl ammonium bromide [CTAB], K+, Zn2+, Ca2+ and Mg2+. Kinetic constant for PPO was found to be km= 15.82 mM and Vmax= 2182 U/ml min using catechol as substrate.Conclusion: Partial Purification of PPO from waste done through a sequential process of ammonium sulfate precipitation, dialysis and ion-exchange chromatography [DEAE- Cellulose]. The best substrate for PPO was identified as catechol [diphenol] and best inhibitor was L-cysteine and ascorbic acid. Â
