Electrical appliances in industrial and residential are now much inductive, consequently causing thepower factor value less than 1 (one), so the power capacity installed to the customer is not optimal.Power factor improvements are needed to improve the efficiency of active power usage so that it canbe maximized. To overcome this, a device is made to automatically improve the power factor due toinductive load changes, ie by installing capacitors in parallel to the source automatically using anArduino-controlled switch when the power factor value is less than 0.85. The test results show that thispower factor repair system is working automatically, real time and recorded on microSD. The powerfactor value can be up to 0.92 with 4.5 μF to 18 μF capacitors at inductive loads of 40 W to 225 Wwith error at 7.06% current sensor, 0.50% sensor, cos phi sensor 4.20%. All measurements aredisplayed on the LCD and recorder on SDCard.

Cilacap Oil Refinery that produces heavy metal waste containing Pb and Cu is located across to themangrove forests along Donan river banks. This study aimed to recognize the role of mangrove forestas biofilters in controlling water pollutants of Pb and Cu that is predicted containing the mangroverehabilitation areas along Donan River banks, Cilacap. The research site was grouped into fourareas, which are control zone (three km before the point source), Inner Zone (at the point source),middle zone (one km point source), and outer zone (estuarine). Four plots were established tomeasure chemical water quality and mangrove tree density. Data colected were then analyzed usingregression model to identify the relationship between mangrove tree density and Pb and Cuconcentration in the water, substrate, roots, and leaves of Rhizophora apiculata. Analysis of variancewere applied among four zones to find out the role of mangrove as biofilters for those heavy metals.The results showed that even though Pb and Cu concentration in the water was not significantlydifferent, however, the concentrations of those heavy metals from the point source to the estuarinezones decreased, especially the concentration of Pb in the substrat highly reduced. Finally, the role ofmangrove forest as biofilter was also recognized from the concentration of Pb and Cu detected in theroots and leaves of Rhizophora apiculata.

One of the free trading impacts in Yogyakarta is increasing the number of promotion media invarious forms, such as free standing signs, roof signs, wall signs, or suspended signs. As a tourism citythat has a market share not only domestic but also international, its usual if the entrepreneurcontinuously compete for its product can be accepted by consumers. The used of advertisements in themain roads of Yogyakarta is one of the promotion stage. But in fact, the development of promotionmedia is almost not suitable with the procedures and even threaten the safety of road users. Itsdiscrepancy happen because the lack of supervision from the government in Yogyakarta. In this study,researcher try to evaluate the effectiveness of billboard placement then assess its structure related tothe safety of road users. Input of the structural assessments is using the dimension of billboard and itsmaterial. From the field survey, there are 58 units of billboards at Gejayan Street, 91 unit ofbillboards at Kaliurang Street, and 40 units of billboards at Monjali Street. The evaluation stepdetailed the pole construction and billboard side then done by structural assessment using SAP 2000.After the structural assessment is obtained, input the result of assessment into the geographicinformation system developed by ArcGIS 10.1. The benefit of using geographic information system isthe data can be integrated from spatial map and additional information such as dimension, crosssection image, and structural assessment. The various kinds of material is dominated by steel and ironwith the range of dimension is about 0,4 until 20 m². The structural analysis result showed that 43% ofbillboards, the pole didn’t have structural reliability and the billboard’s side is not suitable tobuttress, so that they need to change their stucture. The research outcomes if its well applied, it cancontribute as evaluation tools that used by government to discipline illegal advertisement billboards.

Peranakan Etawa (PE) goat farming is one of the growing livestock sectors in Indonesia. 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.

Hypercholesterolemia is still a health problem today because it is associated with the onset of cardiovascular disorders with various complications. 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.) Lam) as a drug for lowering LDL cholesterol.

The development of modern era involves the economic, industrial and population growth and also increase of the social needs which cause the increase of the land needs. Land conversion which happens today has a negative impact on the environment and can damage the potency of the land use itself. One of the negative impacts of the land use conversion which are unwell planned, unwell patterned and not aware with the environment is the increased of the run-off volume due to the decrease the ability of the soil infiltration. If there is no further management of the land conversion, it will cause the increase of the annual peak discharge and has the potential to cause the flood. Green-Ampt is one of the method that can be used to analyze run-off volume by estimating capacity and infiltration rate. In Green-Ampt Method there are some parameters that affect the result of the analysis which are related to vegetal cover and soil parameters such as suction head, hydraulic conductivity, initial moisture, and saturated moisture condition of the soil. The aims of this study are to give the additional information and knowledge related to the run-off volume potency in the study area which has been conducted using Green-Ampt Method for the analysis. Hope the result can be used as the reference in management of water resources potency especially in study area, there are Sub Watershed Pogung, Kaloran and Papringan. From the analysis it is known that there is a different result between observed run-off volume and run-off volume by GreenAmpt Method. The difference of the result can occur because of the different intepretation data on both methods. Analysis by observed run-off volume shows that there are run-off for all of the flood event, while the analysis by Green-Ampt Method shows that run-off only occured in one flood event.

Accessibility of evacuation routes in the multi-storey building is an important thing to notice. The number of floors and rooms in multi-storey buildings which are too many often makes the building users have difficulty, especially for users who do not know the ins and outs of the building well. Not only the difficulty in finding evacuation routes to exit the building quickly in emergency times, but also to find a certain room during normal times. 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. This system can also be used to help the evacuation simulation as a form of disaster mitigation in the KLMB Building.
