Abstract
Batteries are an important component in terms of electricity. It is undeniable that the need for batteries is a primary need at this time. The greater the voltage needed, the more batteries needed to generate electricity. Ultra Step Up converter is a series of dc to dc that can increase the DC energy source. The Ultra Step Up converter has the advantage of being able to increase the voltage with a large enough gain so that the voltage output value is very large with a small input voltage. In this final project Ultra Step Up converter will be developed with constant voltage regulation using Fuzzy Logic Controller. The DC battery source is 48V as input from the converter which will produce an output voltage that exceeds the boost converter output voltage. The advantage of Ultra Step Up Converter is that it can increase the voltage higher than conventional converters such as Boost Converter, and has good efficiency. Based on the simulation results show that the output voltage has reached the expected value of 540V with the initial ripple not too high with a duty cycle of less than 50%. To keep the output voltage constant, the Sugeno type fuzzy logic controller is used.

Abstract
In order to optimize the extraction of antioxidant components from Actinodaphne sesquipedalis leaves, an investigation into the effects of three parameters on DPPH free radical scavenging activity of extracts was studied. Response surface methodology (RSM) was applied to predict optimum conditions for microwave-assisted extraction (MAE) of antioxidative components from A. sesquipedalis leaves. Thus, the objective of this present study was to optimize the extraction condition for the maximum DPPH radical scavenging activity. A Central Composite design was employed to determine the effects of the selected variables, comprising extraction time (20-80 sec), power level (30-60 watt) and ethanol concentration (30-90 %) on the DPPH scavenging activities. Data were analyzed by using Design Expert (version 10.0.1, Stat-Ease, Inc., Minneapolis, MN, USA) statistical analysis software. The optimal extraction conditions for the highest antioxidant capacity were derived at 90 seconds of extraction time, 30 watt of power level and 80 % ethanol concentration that resulted in 92.62 % of scavenging activity. Estimated maximum value at predicted optimum conditions were in good agreement with experimental value. Further research is warranted to investigate the antioxidant activities of A. sesquipedalis leaves extract and their mechanism of action as a basis for future formulation of halal.

Abstract
PART I PRELIMINARY Background Islam is not just to offer guidelines for moral theory to build an economic system, but also sets out a methodology eligible to apply guidelines to the validity of the way and also the legitimacy of the purpose of the foundation on ethical considerations are obvious and can be meaningfully in keseluruan framework of the social order, with the approach of the economic system is highly relevant and urgent to addressed in the economic philosophy of Islamic Shariah. During the first application is very simple and takes place between the two parties. At the present time when the mudaraba entered the world of banking applications development experience. Similarly, the application of bai istisnaa in the construction project. It is the development of the concept of buying and selling taught the Quran and Sunnah. The task of the Muslim scholars throughout history are developing techniques to apply the principles in accordance with the circumstances, conditions and the times. Thus the characteristic aspects of Muamalat (economy) is a broad scope and is elastic, can be developed in accordance with the times and change places. Doctrine muamalat more visible especially in the economy of its universality. This is because in bermuamalat in economics does not discriminate between Muslims and non-Muslims. This fact is implicit in a phrase uttered by the Caliph Ali that in the field of their obligations Muamalat is our duty and their rights are our rights. Economic philosophy of Islam, is the basis of an economic system built on the philosophy of economics that exist, so it can be passed down the objectives to be achieved, for example, the purpose of the economic activities of consumption, production, distribution, economic development, monetary policy, fiscal policy, and so on. In berekonomi let us know what it is philosophy and economic methodology undertaken. In philosophy we must know what we berekonomi with based on the source of the Quran and Assunah. Islamic economic philosophy is based on the philosophical concept of God, man and nature. To carry out economic foundations or should we know the fundamental base as well as the nature or character that we must have. To achieve a good economy and good general point of view according to God should need a way a way that can be called with the methodology. The method is a procedure or a procedure to find something that has the steps systematically. The methodology is very important for science, because with the methodology can be distinguished between the knowledge called science and not science. Formulation of the problem Based on the background that has dikemukan, gained some formulation of the problem. As for some formulation of the problem, namely: How economic principles of Islam? The circumstances of Islamic economics as a life goal? How understanding of Islam, the Islamic economy, and rationality? How metedologi in Islamic economics? Aim Based on the form

Abstract
This study examines the effect of Jakarta Bay reclamation on sea level height generated by storm tide using Regional Ocean Modeling System (ROMS) with tidal data sources from The Oregon State University TOPEX / Poseidon Global Inverse Solution Tidal Model Version 7.2 (TPXO 7.2), wind and atmospheric data from Interim European Center for Medium-Range Weather (ECMWF) Re-analysis (ERA-Interim) with a resolution of 1/8˚. The Simulation is carried out in two stages with the scenario before and after reclamation. Harmonic analysis using data from the model results is used to obtain astronomical tides. the effect of reclamation on water level is seen from the difference in water level from the astronomical tide before and after reclamation. the result shows that the reclamation of the Jakarta Bay is changing the tidal range in the Jakarta Bay to a greater extent. Tidal range changes can reach 0.19 m or 22.4% in Bekasi, while changes in areas that turn into reservoirs after reclamation reach 0.07 m or 7.2% (Western Garuda Reservoir) and changes at flood points can reach 0.09 m or 7.2% (Sunda Kelapa).

Abstract
Historically, the Sunda Strait has experienced several tsunamis recorded in the tsunami catalog caused by several geological phenomena. One of the last tsunami events in the Sunda Strait was the tsunami on December 22, 2018. The condition of bathymetry, coastal topography and high rainfall were some of the trigger factors for tsunamis in the Sunda Strait in addition to the eruption of Mount Anak Krakatau. To anticipate a tsunami in the future, a model of the height of tsunami waveforms that arrived at the coast was made. This study focused on producing rapid predictions of tsunami waveforms arriving at the coast using data signals recorded when a tsunami occurs due to landslide sub-marine. The remarkable training speed requires that it can be used to run in real time conditions and can be used as a tsunami early warning system in near-field tsunami events on the west coast of Banten. The proposed method used non-linear relationships by utilizing Sunda Strait bathymetry data, tide gauge signals, and coastal topography along the west coast of Banten, as well as rainfall during the past tsunami. Therefore, it becomes an advantage compared to ordinary inversion analysis that uses linear assumptions. The results of this study indicate that the extreme machine learning method produces more accurate results with a faster time compared to the inversion method in the propagation, tsunami run-up, and inundation zones on the west coast of Banten. In addition, the uncertainty analysis produced by our model proves that this method is robust and reliable, resulting in a model that can be used as a reference for tsunami safety zones by the local government.

Abstract
The Eastern Indonesian Waters are quite a complex area where this region is traversed by Indonesian Throughflow (ITF) that carries water masses from the Pacific Ocean to the Indian Ocean. The water mass movements have an influence on the condition of the waters in this region, which is the Sea Surface Temperature (SST). The SST has an important role that can control weather and climate. This study aims to analyze the phenomena that occur in the distribution of SST in the Halmahera and Banda Seas. The data used for this research is ten years of SST data (1995-2014) in the Halmahera and Banda Seas. The EOF (Empirical Orthogonal Function) method based on the EVP (Eigen Value Problem) applied to the SST data which produces three main components, that is EOF mode and PC mode respectively. The spatial pattern (EOF modes) shows that SST in the Halmahera and Banda Sea regions, while the temporal pattern (PC modes) shows the cycle of phenomena affecting the SST in these regions. The first mode produces 86.66% variance meaning that the monsoon cycle dominantly affecting SST distribution in the Halmahera and Banda Seas. Whereas in the second mode (6.16%) and the third mode (2.13%) indicating a local cycle and shows that the ENSO cycle has a weakly influence on the SST distribution in the study area. It is also has been clarified by the correlation value between ONI (Oceanic Nino Index) and SST is about -0.245.

Abstract
‘Phu-Chawa- pineapple is a relatively new cultivar of a good fresh consumption quality. However, there is still a lack of information on quality change during low temperature storage of this new cultivar. Being a hybrid between resistant and susceptible cultivar, ‘Pattavia- and ‘Phuket-, respectively, a comparison study between the ‘Phu-Chawa- and its parents was conducted to investigate chemical compositions and internal browning of the fruit after 14 days of storage at 10±2°C, 95±5% RH followed by another three days at 25°C. It was found that ‘Phuket- showed browning symptom score of 4.3, while ‘Phu-Chawa- and ‘Pattavia- exhibited browning symptom score of 0.7 and 0.1, respectively. ‘Pattavia- and ‘Phuket- had similar ascorbic acid content (9.1 and 4.3 mg Ascrobic acid/100 ml juice, respectively), which was lower than that of ‘Phu-Chawa- (22.3 mg Ascrobic acid/100 ml juice). Similarly, ‘Phu-Chawa- and ‘Pattavia- had lower polyphenol oxidase and peroxidase activities than that of ‘Phuket- cultivar. After storage, a decrease in gallic acid but increase in vanillic and caffeic acids were found in both ‘Pattavia and ‘Phu-Chawa- pineapple. In contrary, catechin and 4-hydroxybenzoic acid increased in ‘Phu-Chawa- but decreased in ‘Pattavia- pineapple.

Abstract
Supply chains approaches can be used to solve cayenne pepper-s problems such as unpredictable supply, price fluctuations, uncertainty in production, extreme weather, distribution channels, and price stabilization. Supply chain-s success can be seen from the level of performance. Performance measurement is needed as an approach in order to optimize supply chain networks. The research aims to examine the structure and performance of cayenne pepper supply chain. The study was conducted in Gorontalo and was using survey methods. Data analysis was using descriptive and marketing efficiency analysis. The results showed 1) The structure of the cayenne pepper supply chain in Gorontalo Province consists of seven distribution channels. Sale of cayenne pepper by farmers through collectors (40 percent), wholesalers (26.67 percent), market traiders (10 percent), and retailers (23.33 percent). The primary members of the cayenne supply chain consist of farmers, collectors, wholesalers, out-of-town traders, market traders, retailers, consumers and agroindustries. The secondary members are farm shops, banks, transportation service providers, the Agriculture Service and information media. 2) The most efficient distribution channel is channel six because the smallest marketing efficiency value is 3.17 percent. The cayenne pepper-s market in Gorontalo runs inefficient because it has a price transmission elasticity value of 1.11 (Et> 1). It means the rate of change in prices at the consumer level is greater than the rate of change in prices at the farmers level.

Abstract
The dairy cattle business in Enrekang Regency not only produces the main products of fresh milk which are processed into Dangke (typical food of Enrekang Regency) but also are able to produce by-products in the form of alternative energy. The purpose of this study is to analyze the potential of renewable energy with the use of biogas on peoples dairy farms. The study was conducted in Cendana District, Enrekang Regency in May 2018 to April 2019. Data were collected by observation, interviews, and documentation with dairy farmers using purposive sampling method and analyzed using quantitative descriptive. The results show that feces production potential over the past two years from 804 dairy cows can produce 20.100 kg. Thus, the biogas produced is 1,608 m3/day, considering that one cow can produce biogas at 2 m3/day and 1 m3 of biogas can be used equivalent to 0.62 liters of kerosene and 0.46 liters of LPG gas. Besides that, the potential of biogas energy can meet the cooking needs of one family (4-5 people) for 536 hours or 22 days, considering that the energy contained in one m3 biogas is 2,000-4,000 Kcal or equivalent to 3 hours. Biogas technology has provided many benefits including improving the health of the farmers family, used to process cows milk into Dangke and save on purchasing LPG gas so that it can provide additional income for farmers, even though the resulting value is not large enough, but with a reduction in costs households issued each month.

Abstract
Development of dairy cows outside Java is an alternative effort to increase population and national milk production. Production produced by dairy cows in the form of milk production, livestock production and production of livestock waste into biogas and fertilizer. The presence of a dairy farming business starting from input, process, and output has formed different modes of production. This study aims to analyze the coexistence of dairy farming modes of production that support utilization in producing biogas as a renewable energy source. The location of the study was conducted in Enrekang Regency from April 2018 to May 2019. Data collection through observation, in-depth interviews, documentation, and triangulation then the data were analyzed qualitatively. The results show that dairy farming can coexist with Dangke production and derivative products, the business of selling calves and unproductive cattle as well as farm waste processing business in the form of biogas both controlled by subsistence, commercial and pre-capitalist modes of production without mutually deadly. This shows that the capitalists who grew up in the dairy farming business in Java are different in Enrekang Regency.

Abstract
The challenge for the success of small and medium enterprises in Indonesia is increasing competition that demands adaptation to environmental changes. SMEs fish processing for boneless frozen milkfish in Pinrang Regency has a production capacity of 150 tons per year, potentially producing solid, liquid or gas waste. The purpose of this research is to analyze the potential of SMEs fish processing waste and its utilization in supporting the sustainability of production. The study was conducted in Pinrang Regency from December 2018 to April 2019 with a qualitative descriptive approach. Data collection through field observation, interviews, and documentation. The results showed that the potential of waste produced by 20-30 percent was used as food, feed and fertilizer products. The diversification of the main products into "fish meatballs" and "fish crackers" increases competitiveness and reduction of solid waste. Solid waste is also used to produce by-products in the form of "shredded milkfish" and "fishbone sticks". SMEs fish processing has dynamically applied the concept of clean production in handling and utilizing waste. Waste management has reduced the impact on the SMEs fish processing environment. The implementation of clean production has increased production capacity, product diversification, guaranteed product quality, customer satisfaction, and the welfare of owners and workers. The strategy for handling and managing waste has optimized added value and supports the improvement of competitiveness and sustainability of production.

Abstract
The institutional sustainability of SMEs is determined by the ability of institutions to build an input-process-output relationship and the contingency power of the environment. The purpose of this study is to analyze the relationship between institutional sustainability and the sustainability of production. Data collection was carried out by field observations, in-depth interviews and documentation and data were analyzed using a case descriptive technique. The results of the study show that SMEs of fish processing unit that can operate sustainably is only 38 percent. Institutional Sustainability of SMEs of fish processing unit can be seen from its ability to provide input systems with continuous in quality and quantity; carry out the production process in accordance with the principles of GMP and SSOP dynamically and continuously; the ability to build a product marketing system through extensive network and marketing cooperation; and maintain contingency with the mandate environment; both suppliers, customers and competitors. The contingency power with the political and economic environment supporting the institutional sustainability of SMEs.

Abstract
This study aims to determine and analyze the flexural behavior of the double straight notch joint beam column exterior due to lateral cyclic load. There are 3(three) scale test of specimens, BK monolith, SBK type1 and SBK type2. The joint model used the method of mechanical connection and grouting. A load with alternating lateral assumed as cyclic loads. Tested and analysis used by the displacement control method with the standard of the European Convention for Constructional Steelwork (ECCS) 1986. The results showed that the stability of SBK type1 and type2 specimens in terms of the characteristics of the hysteresis loop curve had a similar curve with BK monolith. The greatest displacement in compressive condition occurs in SBK type 2 while for drag condition occurs on monolithic BK. From the results of the study, It is also known that lateral loads are directly proportional to displacement, where the higher borne of the lateral load that will be more bigger of displacement and vice versa. The displacement ductility that occurs are the partial ductility. Based on the results of studies behaviors type 2 SBK has more advantage than type 1 SBK, So the analysis results of SBK type 2 more validation for monolith BK.
