Fish cultivation business is one of the very promising business with the increasingly cheap demand of fishery products in the community. So is the case with the cultivation of Tilapia fish. Aquaculture is not spared from various obstacles and problems that often hamper fish farming is the occurrence of disease attacks. Tilapia fish Who was attacked The disease starts with by showing signs of behavioral changes. In addition to the behavior, tilapia also experience a change in color that looks very clear difference compared to fish that are still healthy. Calculation of condition factors, from the three sampling sites average fish is in poor condition indicating that most of fish in pond cultivation have decreased condition that reach 60-90%, caused by disease / phatogen factor or environmental factor not good.The results of the laboratory analysis found six (6) parasites that infect tilapia: Dactyloyrus sp, Gyrodactylus spp, Tricodina sp, Vortycella sp, Oodinium sp, and Saprolegnia sp. Water quality is less good in the cultivation are resulted in the decreased condition of fish and support well the development of various types of parasites.

Water is a major component of life processes on earth, good quantity and quality of water is highly coveted by humans. River as one type of waters and become a living medium for aquatic organisms, to measure the level of water pollution one of them by using bioindicator method. Bioindicators are organisms that have biological responses that can indicate the entry of certain pollutants in the environment. The purpose of this research is to know river pollution based on Nutrition Value Coeficient (NVC) fish and Makrozoobenthos that live in it. The value of NVC (Nutrition Value Coefficient) of fish varies on each station in the downstream and upstream segments of the Yeh Sungi river, this illustrates that at each station and on different river segments shows different levels of pollution. Waters with clean categories up to the contaminated waters will be found larvae insect , insects and snails. So on headwaters with macrozoobenthos conditions like this describe the condition of clean waters up to be contaminated, so if associated with the value of NVC fish then the headwaters of Yeh Sungi including the contaminated waters category.

One of the efforts to fulfill the communitys nutritional resources derived from animal protein is by broiler farming business. In order for broiler chickens to achieve optimal productivity then the provision of proper rations in both quality and quantity must be met, but the obstacle in improving the quality of the ration is the cost of ration is large enough. It is necessary to research the feed material that is able to meet the needs of broiler chicken one of them is the leaves kelor. This research used broiler strain CP-707 as much as 60 tail. The method used is CRD (Completely Randomized Design) with 5 treatments and 4 replications. The treatments were rations with no addition of moringa flour (PO), ration with addition of 3% maize flour (P1), ration with addition of 6% maize flour (P2), ration with addition of maize flour 9% (P3), ration with the addition of 12% maize flour (P4). The variables observed in this study were carcass weight, carcass percentage and non carcass percentage. From the results of this study it can be concluded that the addition of moringa flour on ration to 12% level on carcass weight, carcass percentage and non carcass percentage statistically show different not significant.

This study aims to determine the diversity of demersal fish and feeding habits and food habits of demersal fish found in the lower reaches of the Yeh Sungi River. This research was carried out in the lower reaches of the Yeh Sungi River, Tabanan, Bali. This research began on April 17, 2016 until May 1, 2016. The research method used is descriptive exploratory method, namely by conducting a series of sampling activities of demersal fish species to identify the diversity of species and behavior (feding habit) of each type of demersal fish, as well as the food habit of each type of demersal fish. The results of the research on the diversity of demersal fish that have been found in the lower reaches of the Yeh Sungi River are quite diverse, based on the results of the study which captured 14 types of demersal fish in the lower reaches of the Yeh Sungi River. Feeding habits of 14 species found in demersal fish have nocturnal properties, by identifying the physical characteristics of demersal fish, especially in the form of mouths and fins, knowing some types of demersal fish that have adhesive fins prove that the fish look for food by attaching (passively) to the substrate of river rocks and tend to eat moss and detritus and are omnivorous. Demersal fish that do not have adhesive fins tend to be carnivorous and omnivorous, often looking for food by grabbing their prey, especially on the sand substrate on the riverbed. According to the results of analysis of abdominal surgery from 14 types of demersal fish found, 10 body cut objects from macrozoobenthos animals or food habits both intact and destroyed which were then matched with macrozoobenthos data which had previously been found on the bottom substrate downstream of the River. Yeh Sungi, the body pieces are white worms, red worms, silk worms / Tubifek sp, subsequent snails, small shrimp, short snails, dragonfly larvae, insects, detritus and moss.

This study aims to determine the effect of the ratio of glutinous rice flour and the squash to the resulting dodol characteristics, and to obtain the appropriate ratio of glutinous flour and pistachio to produce dodol with good characteristics and acceptable to consumers. This study used Randomized Block Design (RBD) with 6 (six) comparative treatments namely: T0 (100% glutinous flour: 0% squash); T1 (80% glutinous flour: 20% squash): T2 (70% glutinous flour: 30% squash); T3 (60% glutinous flour: 40% squash); T4 (50% glutinous flour: 50% squash and T5 (40% glutinous flour and 60% squash) Each treatment was repeated 3 times to obtain 18 units of experiments. Based on the results, it can be concluded that the ratio of glutinous flour and gourd flakes have significant effect on water content, ash content, crude fiber content, pH, total sugar, texture, aroma, flavor and overall acceptance of dodol squash. The ratio of 70% starch flour and 30% pumpkin yields a good dodol of cauliflower and not significantly different from the control (100% glutinous flour: 0% squash). Characteristic dodol pumpkin with a ratio of 70% glutinous flour: 30% squash is as follows: water content 19.774%, ash 0.763%, crude fiber 0.925 %, pH 6.270, total sugar 14.660 brix, 4.286 (chewy, elastic, non-breakable) texture taste, 3.000 aroma (somewhat typical dodol squash), 4.286 (sweet legit) flavor, overall acceptance 5.714 (likes) and all these characteristics meet per the requirement of SNI dodol (SNI 01-2986-1992).
