The objective of thepresent study was to increase aquaculture production sustainably in floating cages and to enhancebroodstock production, feed-fish stock  and fish consumption harvested by sero and FAD in order togenerate integrated business incubation in favor of fish consumption in Southeast Sulawesi. The studywas conducted in Staring Bay, South Konawe Regency, Southeast Sulawesi. This study identifiedbroodstock and consumed fish harvested from sero and FAD, the collection of fish to be stocked infloating cages, broodstock adaptation and fish rearing on floating cages, and fish production to reachmarketable size. Results showed that there were 1,500 broodstock of Caranx sp., harvested from sero,and 180 broodstock of lobster with the size ranges between 200 and 220 g/individual collected bybamboo fishing trap (bubu) placed in FAD. During the study, the survival of  Caranx ignobilis, andlobster reached  between 84.25-88.15% and 92.33%, respectively. The fish were fed fresh trash fishharvested from sero and FAD. The production of fish consumption post harvest ranged from 380.5-560 kg/month. The agro-marine model contributes to an optimal production and minimizes productioncost of aquaculture and also increases fish consumption sustainably.","PeriodicalId":159255,"journal":{"name":"Jurnal Nasional Teknologi Terapan (JNTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131007670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indonesia needs a sustainable breeding system that can guarantee the availability of goats. Estrus synchronization is a necessity that can help uniform the breeding time and manage the time of pregnancy and birth. Artificial estrus synchronization techniques that use a combination of Prosterone and Zinc minerals give good results of estrus synchronization in goats. The Aim of this research is to understand the combination efectiveness of estrus synchronization technique with progesterone acetate and Zinc supplementation. The design of this study used two treatment groups, each group consisting of three does PE goats. Estrus synchronization of experimental animals in treatment 1 and 2 was carried out using polyurethane sponge implant method which contained medroxi progesterone acetate 60 mg. Group 1 was given Sponge Progesterone for nine 9 days while giving Zinc (Zn) mineral supplement (Elemental Zn 20 mg, Kimia Farma) orally given 7 times. The frequency of Zinc administration every day begins during intra vaginal sponge insertion. Group 2 was treated same as group 1 with 14 days of implant time and 7 times of Zinc supplementation.The results showed that both treatments occurred estrus simultaneously with good estrus quality. Both treatments show the results of the estrus 8 score assessment with the estrus 3-9 range. The maximum estrus quality’s value of group 2 was higher (8.33 ± 0.57) compared to group 1 (8.0 ± 1.0). The estrus duration of group 2 occurs for 24 hours and group 1 for 7 hours. Estrus onset of Group 2 is earlier (58 hours) than group 1 (75 hours). Both treatment groups showed an increase in temperature at period of the occurrence of estrus. Body temperature during estrus time was 38.7 ± 0.20 0C to 39.60 ± 0.26 0C. The conclusion of this study is that in both treatments of estrus synchronization using sponge progesterone and zinc supplementation can cause estrus synchronization effectively . The duration of estrus in group 1 (9 days of implant) was Shorter than group 2 (14 days of implant). The onset of estrus time of group 1 (9 days of implant) was longer than Group 2 (14 days of implant). The body temperature of the experimental animals increases with the occurrence of estrus.","PeriodicalId":159255,"journal":{"name":"Jurnal Nasional Teknologi Terapan (JNTT)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124914480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High cholesterol levels carried by the blood will accumulate in the arteries that cause atherosclerosis. Blood clots and blockage of blood vessels can result in the stroke or heart attack. Flavonoids that are found in purple sweet potato leaves are quercetin. Quercetin has antioxidant effects that can improve blood vessel endothelial function, reduce LDL sensitivity to free radical effects, and reduce blood lipid levels. This study aims to determine the effect of ethanol extract of purple sweet potato leaves on LDL cholesterol level of hypercholesterolemia rat. The experiment was conducted experimentally using 2 groups of Wistar rats (each group consisting of 5 tails), namely the control group and the treatment group. Induction of hypercholesterolemia was performed with a high-fat diet for 7 days. The purple sweet potato ethanol extract was administered sonde in the treatment group with a quercetin dose of 2 mg /kg/day for 14 days and the measurement of LDL cholesterol was performed on days 10 and 24 by the CHOD-PAP method. Data were analyzed by Paired t-test. The results showed that LDL cholesterol level in the treatment group showed that 5 mice had decreased, the mean decrease of 32,49 mg/dl while control group 3 decreasing, mean 0,65 mg /dl. There was a significant difference (p <0.05) on changes in LDL cholesterol levels in the treatment group. Provision of purple sweet potato ethanol extract with quercetin dose of 2 mg/kg for 14 days can decrease LDL cholesterol level of hypercholesterolemia rat. From the results of this study is expected to optimize the utilization of purple sweet potato leaves (Ipomoea batatas (L.)

Nowadays, the Network Analysis capabilities in Geographic Information System (GIS) have become more reliable, even able to accommodate 3 Dimensional aspect (3D) which is often known as 3D Network Analysis. Therefore, this research intends to apply 3D Network Analysis for developing the navigation and evacuation management system in the KLMB (Klinik Lingkungan dan Mitigasi Bencana) Building Faculty of Geography UGM which has 6 floors. Generally, the implementation of this research can be divided into 4 main stages, namely Data Collection Stage, 3D Network Dataset Preparation Stage, 3D Network Analysis Implementation Stage, and Test & Evaluation Stage. Through application of the 3D Network Analysis, this research successfully obtained a navigation and evacuation management system in the ArcScene (ArcGIS) software environment which is quite effective and easy to use to help navigation and determination of the fastest evacuation route in the KLMB building.

Erodibility factor (K) from the Universal Soil Loss Equation (USLE) in this study was the result of soil erodibility estimation or soil capability to be dispersed by rain. K factor was affected by soil organic, soil permeability, soil structures, and soil textures.

This reservoir was used to distribute water and irrigation to all Kulonprogo District and especially to keep the sustainability of sedimentation of soastal area di Glagah Beach. All of soil properties was collected in each landform of Serang Watershed and was analyzed by laboratory measurement. By using K factor formula, the K value can be estimated.
