Abstract
The tourism sector is one sector that contributes significantly to the process of development and regional development by contributing to the level of tourist visits that will have an impact on the government and local communities. Baron area is a superior area in Tanjungsari District. Based on the Tourism Development Master Plan (RIPPDA) of Gunungkidul Regency, the Baron Region is an integrated area with functions in the education and tourism sector. This is supported by the existence of the Baron Coast area as marine tourism and Baron Techno Park as an educational tour. The study question here is: What is the impact of the existence of the Baron tourism area on social economic aspects of the community and land-use change? The problems that arise in the development of the Baron tourism area are the unintegrated development between tourism objects and the uneven economic impact, so the researchers want to examine the impact that the tourism area has on the economic aspects of the local community and land-use change. The research approach uses a quantitative approach with quantitative descriptive analysis and time series mapping analysis methods. The technique used is random and purposive sampling technique based on data sources obtained from primary data through field observations and interviews. Besides, it also includes secondary data collection from document review. The results of the research study show that the influence of tourism on economic aspects predominantly only occurs in Baron Beach. The influence is the change in employment opportunities and shifts in types of work from fishers to tourist attraction businesses. The change in land use is indicated by the development of attractions and businesses supporting the tourism sector, namely trade and services from 2014-2017. While the influence of economic aspects for the business community in Baron Technopark is still minimal, this condition is influenced by the trend of the number of visitors who are still small and selling areas that are still outside the tourist attraction. It can be concluded that there has not been integration between attractions in the Baron Region on the improvement of the peoples economy. Attraction integration is still limited to function. It is necessary to develop an integrated tourism area both in terms of spatial pattern and spatial structure. The spatial pattern is related to the integration of the intensity of spatial use, namely the planning of marketing and distribution locations.Spatial structure is related to connectivity between tourist objects so that it can encourage an increase in the peoples economy more evenly.

Abstract
Abstract - Majority of agriculture in Indonesia still relies on rainwater for irrigation. In dry season, there are many agricultural lands become unproductive. It decrease farmers income. To solve this problem, Aquaponic Planting System was offered but the system is complicated. It needs adequate oxygen and suitable pH to ensure nitrification process to occur. In nitrification process bacteria convert NH3 to NO3- and NO2. Therefore, a system which controls oxygen and pH levels are needed. For pH calibration, curveting method was used to get accurate measurement. For oxygen calibration, saturated dissolved oxygen water was used. It was obtained by using Potentiometric method. Finally, A Simple Moving Average was used to get stable readings.

Abstract
Biji klabet mengandung polifenol yang dapat berfungsi sebagai antioksidan alami. Polifenol merupakan senyawa yang bersifat polar dan berpartikel besar sehingga mempunyai keterbatasan dengan tingkat penetrasi yang buruk ke dalam membran biologis yang kaya akan lipid. Teknologi fitosom dapat meningkatkan penetrasi zat aktif ke permukaan kulit dengan terbentuknya nanovesikel dan mempunyai profil stabilitas yang lebih baik dibandingkan ekstrak. Penelitian ini bertujuan untuk mengetahui pengaruh fitosom terhadap stabilitas fisik masker peel-off. Fitosom yang digunakan dalam penelitian ini dibuat dengan metode hidrasi lapis tipis dengan perbandingan ekstrak dan lesitin 1:1 (F1) dan 1:2 (F2). Masker peel-off terdiri dari 4 formula yaitu Formula I (tanpa ekstrak dan fitosom), formula II (dengan ekstrak), formula III (dengan fitosom F1), dan formula IV (dengan fitosom F2). Hasil uji stabilitas menunjukkan bahwa formula masker peel-off yang mengandung fitosom lebih stabil ditunjukkan dengan tidak adanya perubahan secara organoleptis dan pemisahan fase serta tidak adanya perubahan pH dan viskositas yang signifikan. Berdasarkan analisa statistik pH dan viskositas dengan anava dua arah dengan taraf kepercayaan 95% (α = 0,05) didapatkan hasil adanya perbedaan pH dan viskositas antara formula I, II, III dan IV dan dapat dikatakan bahwa penggunaan ekstrak ataupun fitosom dalam formulasi sediaan mempengaruhi peningkatan pH dan viskositas masker peel off.

Abstract
Poverty is a major problem of development. It is often found in developing countries, including Indonesia. Sukabumi Regency, West Java has a population of 1,164,018 people. Of these, there are 309,785 agricultural households, where the number of small farmers who have agricultural area less than 0.5 hectares, counting 244,688 households. The farmer-s income cannot sufficient the needs of their family, because it is far below the UMK (Regency Minimum Wage). The study is trying to discover the role of Agriculture Department in poverty alleviation of farming communities through collaborative governance in Sukabumi District. Descriptive qualitative and data collections such as observation and interview were used in the research. It is involved 21 people. The research showed that to overcome the decreasing poverty number, Department of Agriculture has carried out programs and policies, namely agricultural counseling by Field Agricultural Instructors (PPL), seed supply, education and training for PPL on the importance of developing the human resources so that the poverty rate of the farming community in Sukabumi is reduced. Collaborative governance is carried out not only between the Government of Sukabumi Regency and the private sector, but also with the farmers communities in agricultural products marketing, but this has not been optimal. The research recommendation is the active role of the Sukabumi Government, specifically Agriculture Food Crops Department to reduce poverty in the agricultural community.

The authority of the nurse in carrying out professional duties is regulated in Minister of Health Regulation No. 148/2010 so that the nurse has legitimacy in carrying out the practice of his profession. Related to the authority and duty of the nurses, they also have liability that need to be protected by professional indemnity insurance. This is certainly based on Law Number 40 of 2014 concerning Insurance. The responsibility of the nurse when making a mistake (negligence) in carrying out his duties at the hospital is possible to be transferred to the hospital through insurance coverage. In this case the hospital acts as the insured and the insurance company as the guarantor. The hospital is obliged to pay a premium to the insurance company. The method of this article is normative method, which allows authors to explore the topic in depth with two approaches, conceptual approach and statute approach. The conclusions of this paper namely are first, the nurses as a professional in the field of health is very important to be protected throgh professional indemnityinsurance. Second, in this case the hospital acts asthe insured; on the other hand, the insurance company is an entity which provides insurance. The hospital is obliged to pay aninsurance premium to the insurance company as insurer. Keywords : insurance, professional indemnity, nurse profession

Abstract
Copper Indium Gallium Selenium (CIGS) is one of high-performance solar cell among the other second generation of solar cell. The common method to fabricate CIGS solar cell use vacuum method such as evaporation, vapor transport deposition and electron-beam deposition that require high technology investment and expensive. The aim of this study is to investigate the synthesize of CIGS thin-film using a non-vacuum method as CIGS ink and coated by spin coating. The CIGS ink was synthesized by dissolving copper (II) acetylacetonate, gallium (III) acetylacetonate, and indium (III) acetylacetonate with oleylamine in a nitrogen atmosphere and then the solution was mixed with selenium and heated. The ITO substrate was coated by ZnO layer and then coated by CIGS using a spin coating method to make CIGS solar. The samples were characterized by XRD for crystal structure properties, SEM-EDX for morphology and chemical element analysis. The optical properties were performed by UV-Vis spectrometry. The results show that CIGS was successfully synthesized. The photoresponse and power conversion efficiency solar cell of the CIGS/ZnO film will be discussed.

Abstract
Lots of duku (Lansium domesticum Corr.) Rupit trees have died in the past ten years. However, no high yielding seedling is available for replanting. In this respect, in vitro propagation offers a perfect solution because it allows growers to get millions of pathogen-free and uniform seedlings at a very short of time for rootstocks. The objective of thi experiment was to have the best combination of 2,4-D and BAP in inducing the growth of duku explants. The experiment was conducted from February to June 2018 at the Tissue Culture zlaboratory of the Department of Agronomy and laid in Completely Randomized Design. Seeds of duku were grown in MS media supplemented with 2,4-D (1, 2, 3 ppm) and BAP (2,3,4 ppm). The results showed that all of the media tested produced callous, with different time of formation and qualities. Also, all media produced shoots, but only MS media supplemented with 2 ppm 2,4-D and 2 ppm BAP produced leaves. However, no media produced any root.

Abstract
Aceh-s patchouli is one of the superior local commodities, and its growth and yield could be improved in various means. One way to increase the patchouli production can be done by using bio-fertilizer mycorrhizal local strain. The purpose of this research was to study effect of bio-fertilizer mycorrhizal local specific strain on the growth and yield of patchouli in Entisols. The research was arranged by a non-factorial randomized block design with three replications. The investigated factor was the bio-fertilizer mycorrhizal from local specific strain with four levels, i.e. M0 (without mycorrhizae), M1 (Glomus mosseae), M2 (Gigaspora sp) and M3 (Mixing between Glomus mosseae and Gigaspora sp). The variety of patchouli used in this study was the Tapak Tuan variety. The observed parameters were plant height and stem diameter of patchouli at 45, 60 days after planting; additionally the parameter of patchouli yields consist of number of leaves, number of branches and weight of leaves were observed at 90 days after planting, and root colonization by mycorrhizae. The results showed that mixed mycorrhizal strains between Glomus mosseae + Gigaspora sp contributed to the best marks for increasing growth and yield of patchouli in Entisols. The similar trend result was also found in the root colonization by mycorrhizae. The strain of mycorrhizal of Gigaspora sp application was not effective for increasing the growth and yield of Aceh-s patchouli in Entisols.

Abstract
Organic contaminant is one of the environmental issues in wastewater. Organic contaminants in wastewater may produce toxic chemicals during disinfection. Nowadays, food industries and restaurants are the main contributor of organic contaminant in wastewater. Organic contaminant caused the increase of BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid), and decrease DO (Dissolved Oxygen). The purpose of this article is to evaluate the efficiency of removing organic contaminant from wastewater with natural biofilter from banana tree. The efficiency of banana tree was analysed in terms of decreasing BOD, COD and the content of TSS. The parts of banana tree that can be removed organic contaminant from wastewater is its stem. Banana stem used as media natural biofilter because of its abundant availability in Indonesia. The disadvantages of banana tree was it can be easy placed by bacteria. Bacteria will develop well on banana stem because banana stem is moist enough and consist of much water in it. Banana stem contains cellulose fibers that can be used as media biofilter because the characteristics of it, such as abundantly available, biodegradable, renewable, cheaper, low abrasive nature, interesting specific properties, and exhibit good mechanical properties. However, the disadvantages of cellulose fibers were low thermal stability, moisture absorption, and poor compatibility.

Abstract
The wastewater treatment process has various kinds of problems that can disturb and hinder the treatment process. Problems that usually occur are wastewater contains strong and irritating odor. Based on the production of different amounts can change the characteristics of effluents. The amount of organic variation decreases the effectiveness of biological processing and others. So based on this a good solution is needed and can expedite the treatment of wastewater. Bioactivator is an excellent material that can be used. Bioactivator consists of naturally occurring microorganisms attached to organic compost. It quickly stimulates the bacteria in situ so that the waste quickly decomposes. In the process, it prevents the generation of smells. Bioactivator is entirely natural and it does not contain any hazardous or poisonous chemicals or enzymes. Bioactivator also prevents the generation of odors, increases the metabolic of bacteria. It is most effective on organically overload treatment plants it increases treatment plant capacity. Bio activators can come from soils where soils contain lots of microorganisms. The amount of microbes found in the soil depends on the type of soil. Soil consists of micro and macrofauna and flora which provide a large carbon source and a large number of microorganisms. So in this paper by utilizing microorganisms in the soil as a bio activator for wastewater treatment.

Abstract
Composting Process is an alternative organic waste management for degradation waste generation. In general, bioactivator will be added to the organic waste mixture which aims to accelerate the process of maturing compost and not forgetting the quality standards of it in order to apply to the soil so that the environment will stay in a healty condition. There are various types of bioactivators that used in the composting process such as EM-4, Acticomp, Orgadec, and also bacteria which can be produce using various source organic matters such as vegetable waste. Vegetables waste is a good medium for growing microorganisms, and it can be use as bioactivator in the composting process. Another advantage of using this source is that vegetables waste are cheap and easy to find because they usually thrown away and not reused. Some researchers found bacterias like Streptococcus, Leuconostoc, Lactobacillus, and Pediococcus are contained by vegetables that will create lactic acid fermentation .This bacterias has an important role to change various sugars in vegetables waste, especially into lactic acid which when compost is given to the soil, bacteria will play a role to control the pathogenic organisms. Some studies about bioactivator from vegetables waste relationship has been done related to the compost quality result from the addition of the environmental biaoctivator from vegetables. In this article, there will be reviews from various research journals related to the making and application of bioactivator from vegetables in the composting process and to find out whether the use of vegetables waste are good bioactivator for composting process.

Abstract
The research was performed in July to August 2019 in Arjowilangun Village, Kalipare District, Malang Regency. The first-two stages of action research in this study, namely Diagnosis and Action Planning, were carried out to underpin the next stage of research activities. Twenty goat informants and sheep farmers were chosen by using purposive sampling technique and data were collected by FGD (Focus Group Discussion), interview and observation. In the diagnosis stage, main problems of the community lied in the goat and sheep production and waste management, particularly feed problem in the dry season. In the action planning stage, farmers were motivated to find their feed problem solutions based on village-s potential resources (forage, corn and sugar cane waste). It is necessary to do goat and sheep waste processing training (e.g. Bokashi) to solve other farmers- problems. It can be concluded that the empowerment program achieves most of its objectives. The community can point out their problems and potential, also manage their problems in the correct method

Abstract
Obesity is one of the risks of various diseases and can reduce the beauty of the body, especially mothers. From the survey data conducted by many mothers always complained by the name of gaining weight because they did not exercise while the food patterns were also not regulated they tend to prefer fast food (jungfood). Therefore one type of exercise used to reduce body fat is to do aerobic exercise. The success of decreasing body fat can be seen with aerobic exercise training models through the Circuit training model and body language training. In addition, it can also be seen from the consistency of exercise, adequate diet and rest, so that instructors need innovation or variation by applying appropriate training models. The research method used in this study is the experimental method. This research was divided into two treatment groups namely the experimental group and the control group. The two groups were tested for their initial conditions, before being given different treatments. In the experimental group the implementation uses the circuit training model, while the control group uses the body language training model in the implementation. At the end of the treatment the two groups were measured using tests and measurements using a skinfold caliper from Ismaryati (2006: 90). The data analysis technique in this study used a 2x3 factorial design variance analysis (ANAVA) technique at α = 0.05. With the normality test (lilliefors test) and the Homogeneity Variance test (with Bartlet test). The results of this study indicate that: 1. There are differences in the effect of the application of the circuit training model and the body language training model on decreasing body fat (Sig. 0.013 <0.05). 2. There is a difference in the effect of gymnastics mothers who have underweight, normalweight (ideal) weight, and overweight weight on the reduction in body fat (Sig. 0.000 <0.05). 3. There is no interaction of influence between exercise model and body weight on body fat reduction (Sig. 0.959> 0.05).

Abstract
Fuels are needed to run vehicles. The use of fuels by motorist seems to have an impact on corrosion rate of the fuel tank. Corrosion can result in perforated fuel tank and this can be dangerous for motorists. So that, further investigation related to the use of fuels on fuel tank corrosion resistant is essential. Previous research had already explored tank corrosion resistance (without surface treatment) using pertalite and pertamax and the finding showed that corrosion rate was quite high. Thus, in this current study, before testing the corrosion rate, the tanks were electroplated. It is expected that this could reduce the corrosion rate. This research was initiated with the preparation of material and tools, the cutting of fuel tank, and the electroplating of nickel. Then, it was followed by corrosion testing by using variety of pertalite and pertamax. The value of corrosion rates indicated corrosion resistance. The result of this study revealed that the corrosion rate of fuel tank using pertamax was smaller than that of pertalite. The value of corrosion rate of pertamax was 0.020 mmpy while the corrosion rate of pertalite was 0.023 mmpy.

Abstract
Water is one the determining factors in the process of agricultural production. In meeting the needs of water for various farming needs, it must be given in the right amount, time, and quality, otherwise the growth of plants will be disrupted so that it will affect the production, productivity and income of farmers. The purpose of this study is to analyze the differences in productivity and income of farmers who work on semi-technical irrigated rice fields with farmers who work on simple irrigated rice fields in Baubau City. The population in this study were 214 farmers, 102 farmers with semi-technical irrigation and 112 farmers with simple irrigation. For the purpose of this research, 25 farmers were taken from each of the two irrigation categories. Data analysis with a different test (t test). The analysis shows that there is a very significant difference between the productivity and income of farmers who work on semi-technical irrigated rice fields and those who work on simple irrigated rice fields. for productivity. While the income is (7744621.9057> 2,485) at 99% confidence level.

Abstract
Landslides is typically caused by heavy rain in some locations that have a certain slope of land compounded by deforestation or earthquakes. For instance, in 2018 there were 148 reported landslides in the Banjarnegara highlands, Indonesia. By using that fact, some research has been done. The research is about the indicator parameters of landslides by combining rain gauge sensors, soil moisture sensors, ground shift sensors and groundwater pressure sensors using Arduino Promini. The data from sensor is sent through LoRa Bee to the database server using NodeMCU ESP8266 which is connected to the Internet in realtime through access points. The data that has been sent to the server will be processed and displayed on the website. In this paper, the author devise an algorithm for analyzing the data from each sensor to a decision-making strategy. The decision-making method for an early warning of landslides uses a decision tree that compares the measured parameters with a predetermined threshold of each sensor. After analysis and testing, this system is expected to provide early warning of the landslides quickly and accurately.

Abstract
The condition of an effective and efficient marketing system can be used in support of the existence of price information which is not only known to traders but also related to farmers so that farmers do not depend on weak positions as recipients of low prices. Search results show the cashew nut flow formed in the marketing channel can be grouped into cashew nut flow that occurs with different market participants and marketing activities, as well as short differences. This is based on meta logs which are the raw material for producing cashews. The purpose of this study was to analyze the performance of the cashew nut market in Southeast Sulawesi. Quantitative descriptive analysis is also used to measure marketing efficiency, technical efficiency, economic efficiency. The current condition of cashew marketing requires a decrease, this overcomes various factors. To find out these factors, a marketing system analysis was carried out on various parties involved in the marketing process of cashew nut. The conclusion of this research is the cashew marketing channel which achieved the most inefficient increase was channel pattern III by 94%, technical efficiency index 16.95, economic efficiency index 1.23 with the destination area of Central Buton.
