Abstract

Coconut processing industry produces a by-product or shredded coconut husks limbahberupa. The main advantage of the dregs of coconut food fiber  is high, which proved instrumental in the prevention and control of various chronic diseases such as colon cancer, heart attack, hypertension, stroke and diabetes mellitus. This research aims to produce products made from flour, coconut dregs have a good nutritional quality and food high in fiber so it is expected to become a functional food ingredients. This research use the sample waste dregs of coconut derived from shredded coconut seller in the traditional markets of coconut husks and waste from industrial Virgin Coconut Oil (VCO), then waste coconut husks that are washed, boiled, dried and milled into flour so that the coconut husks. Based on data proksimat the flour coconut pulp market has food and fiber carbs are lower while levels of protein, fat and vast grounds higher than the flour coconut husks VCO.Analysis of microbiological by-product of coconut flour shows VCO has sanitation and food security is better when compared to the dregs of coconut flour market. Key words: Waste, Coconut Dregs Of  Flour, Proksimat, Microbiology

Abstract

Biopori is pore space or in the ground formed by living creatures, such as microorganisms of the soil and plant roots. The shape resembles biopori hole in the ground and forked branches and very effective to channel water and air into the soil. In order to make the hole biopori still function optimally it should be routine coupled with organic material, so in the hole biopori absorption will still take place in aerobic composting process by soil microorganisms.The addition of microbes in accelerating the process of degradation of the garbage that is by adding a inoculum composite comprising four microorganism Saccharomyces,  Lactobacillus, Acetobacter sp., and Bacillus. The addition of the best treatment with the addition of inoculum and soil, have physical characteristics that resemble the physical characteristics of the soil. Key words: Biopori, organic waste, microbes

Abstract

One of problems that frequently occursin hospital management is nurses scheduling problem. A suitable schedule is needed in order to avoid fatigue, both physically and psychologically, which subsequently may deteriorate their performance. Nurse scheduling is commonly designed by the head of nurse manually. In this research, a cyclical nurse scheduling problem is modeled in the form of an integer non-linear programming. The objective of the model is to minimize the number of nurses which works for 30 days. Then optimization problem is implemented to nurses scheduling in the Rumah Sehat Terpadu Dompet Dhuafa Parung Bogor. Key words  : Integer Non-Linear Programming, Optimasi, scheduling cycle

Abstract

Unionidae Shells have a potential economic importance for humans.  These shells can be used as commodity farming inland fisheries due to the their flesh can be eaten, have a protein content 7.37 grams in 100 grams of meat, the shell is useful for industrial raw material studs and animal feed, as well as this animals can be cultivated as a pearling. The purpose of this research is to know a good way where maintenance against the growth of Anodonta woodiana Pearly shells, Lea. materials in this research is the parent of mussels reared in freshwater pool with two different ways, first is hanged in koja (basket and second way is removed at the bottom of the pool. Monitoring the quality of the physics and chemistry of water is done every week i.e. parameters: temperature, pH, DO, NH3, calcium, debit and brightness. Identification of plankton swimming is done every week. Clam growth measured on a weekly basis: average weights, Ø length of the shell, the shell width, Ø and Ø thicker shell and survival. Average weight of shells and shell growth being maintained well with the observed two different ways during the 6 week look is always incremented even though relatively slow. Maintenance of basic dribbling off better against the survival and growth of diameter shells compared to how hung in various spices. Key words : Anodonta woodiana, Lea, was hanged in the basket, off base.

Abstract

Fish eggs semah in cultivating on average only hatch of 67%, so still far stated well and need to do a proper egg incubation technique to increase the degree of hatching. Efforts are being made at other hatcheries as Catfish is using the technique of egg incubation method of stagnant water and MacDonald jars, but this system still has flaws, that can lead to poor water quality (stagnant water) and the presence of abnormal larvae (Mac Donald jars). In this study, the technique of egg incubation is carried out using a multilevel system tray modification. The results of the use of multilevel system tray in Aquarium shows very different real power against egg hatch (HR) fish semah, whereas against an increase in the degree of abnormality of fish larvae semah influence is relatively the same.The use of 3-floor tray (A3), can enhance degrees most high 89.19% hatching, larval fish and the degree of abnormality 1.63%.                                                                                                      Key words : System tray multilevel, tetas power eggs (HR), the degree of abnormality, Tor douronensis

Abstract

Sargassum crassifolium is a species that is included in the class Phaeophyceae.  This Brown algae is a alginat source manufacturer and contain active compounds include flavonoids, saponins and triterpenoid which function as antibacterial, antiviral and antifungal  properties. The purpose of this research is to know the activities of Sargassum crassifolium in inhibiting the growth of Candida albicans and phytochemicals content. The extraction is done using the method of maceration. Test the effectiveness of antifungal performed using diffusion agar method and paper discs. The parameters observed were drag area width. Data was analyzed using Anova with a level of confidence of 95%. The results showed that the average diameter of the drag area extract Sargassum crassifolium is most effective on a 75% concentration of 21.6 mm. Phytochemical analysis shows that Sargassum crassifolium contains the active compounds such as flavonoids, saponins, and triterpenoid. Key words  : Sargassum crassifolium, Candida albicans, antifungal
