Abstract
The potential of wind energy in Indonesia is generally relatively less compared to other countries in the subtropical region. With the Darrieus VAWT Type Vertical Axis Wind Turbine, the turbine does not have to be directed to the wind to be effective. Mill with vertical axis, generator and gearbox can be placed near the ground, so the tower does not need to support it and is more accessible for maintenance purposes. Gearbox is one of the main components of the motor which is referred to as a power transfer system, the transmission functions to move and change the power of the rotating motor. To get a large turbine torque, a gearbox design (large size on the turbine and a smaller size on the rotor generator) is needed. The number of blades used will also affect the effectiveness of the turbine in capturing the wind. With the number of 3 blades, get torque above 40 rpm, at wind speeds of 4.5 to 5 m/s.

Abstract
Renewable Energy Resources are increasing in a few years, this is due to the increasing increase in environmental pollution and fossil fuels which are increasingly depleted. Both bridges and toll roads actually have wind speeds that can be used and used as electricity. But there is a problem to put the power plant on the bridge or the toll road, which is quite limited land, so to install the Horizontal Axis Wind Turbine will be very difficult. Therefore Vertical Axis Wind Turbine is used as an alternative. VAWT is used to create power plants that can use wind from vehicles on toll roads and bridges to make electricity.To be able to take advantage of the wind around the place, Computational Fluid Dynamics (CFD) is needed to optimize the design of the turbine.

Abstract
We present a novel alternating joint inversion algorithm for controlled-source electromagnetic (CSEM) and seismic data. The two different physical parameters, i.e., the electromagnetic (EM) resistivity and seismic velocity, are correlated using the structural constraint during the inversion. The structural coupling used is the joint total variation (JTV) constraint, which is incorporated into the objective function of the individual EM or seismic inversion to enforce the structural similarity between the resistivity and velocity. The conventional cross-gradient constraint is not preferred as it can only be used for enforcing structural similarity for 2-D or 3-D case since it is always zero for 1-D joint inversion. The JTV constraint can be applied for 1-D joint inversion, as well as for the 2-D/3-D case, which is of a broader interest. The improved Gauss–Newton (GN) is used for minimizing the objective function and for reconstructing the subsurface resistivity and velocity. The alternating joint inversion algorithm is applied for integrating the CSEM data with cross-well seismic data for subsurface reservoir evaluation and water–oil identification. Numerical examples show that the developed joint inversion can improve the inversion results significantly over those from the separate EM or seismic inversion.

Abstract
Main text: The Lutao hydrothermal field is an intertidal arc-volcanic system located at offshore southeast Taiwan, hosting a Zhudanqu (ZDQ) vent and a Huwaichi (HWC) spring. The totally depleted Mg, moderately enriched chloride and H+ with respect to seawater indicated that the ZDQ endmember was solely derived from the brine phase resulted from low-degree subcritical phase separation. The vapor phase comprised the endmember for the HWC vent fluids. The temperature and pressure of the phase separation were estimated as ~ 150 oC and ~ 5 bar, respectively. The water/rock ratio was calculated as about 2. The Lutao hydrothermal system was slightly affected by semi-diurnal tides, either by tidal loading, or tidal currents, or a joint effort of both. The active circulation period of the Lutao system was about 3 h according to the time delay of its response to tides. Freshwater was almost absent in the HWC vent fluids at normal conditions. The typhoon Fung-wong that attacked the island on Sep 21st, 2014, however, imported freshwater into the vent fluids with a percentage of ~ 16%. Both the ZDQ and the HWC endmembers were a little changed after the typhoon event, suggesting a cooling of the reaction zone. Presumably, the seawater was cooled by the tropical storm by 2-5 oC which consequently quenched the reaction zone and declined the degree of phase separation. After the typhoon passing by, the hydrothermal system began to recover, evidenced by increasing percentages of the HWC endmember and decreasing freshwater contributions. The flux of the HWC endmember was estimated as ~ 500 L h-1 based on these observations. This study, for the first time, reports a shallow-depth hydrothermal system that was cooled by a tropical storm and affected by tides.

Abstract
The extents of wave-driven flooding along the coastline fronted by fringing reefs during severe weather depend on the state of the reef. It is believed climate change will result in a net increase in the water depth over the reef flat, a degrading of the surface roughness of coral reefs and changes in extreme incident wave heights. For a better understanding of the impact of climate change on wave-driven flooding hazards over reef-fringed coasts, this study utilized a Boussinesq wave model, FUNWAVE-TVD, to simulate irregular wave transformation and run-up over fringing reefs. Validated with experimental data, the present model shows reasonable prediction of irregular wave evolution and run-up height. Numerical experiments were then implemented based on the anticipated effects of climate change and carried out to investigate the effects of sea level rise, degrading of the reef surface roughness and increase of extreme incident wave height on the irregular wave run-up height over the back-reef beach. Variations of spectral components (i.e., significant sea-swell run-up height, infragravity run-up height and 2% highest run-up height) of irregular wave run-ups were examined and discussed to better understand the underlying physical process.

Abstract
In 2016, we carried out a coincidental multi-channel reflection seismic and wide-angle reflection/refraction seismic experiment along a 320-km long profile across the northeastern margin of the South China Sea (SCS). Based on these new data, we studied velocity structure of the transitional continental crust using both ray-tracing based seismic phase modeling and travel-time tomography. The velocity model shows that Mesozoic sediments have velocities of 4.3-5.3 km/s and are about 3-6 km thick in the magnetically quiet Chaoshan Depression and the attenuated transitional continental crust. This confirms that it is this thick layer of weakly magnetized Mesozoic sediments that causes the magnetic quiet zone. This Mesozoic layer pinches out seawards near the continent-ocean boundary. Two apparently isolated high-velocity anomalies are revealed in the lower crust of the continental slope. The first has velocities of 7.0-7.5 km/s and a maximum thickness of 8 km, and the second has velocities of 7.0-7.3 km/s and a maximum thickness of 3 km. We find that the discontinuity of the high-velocity zones is not due to the lack of some seismic phases or lose of a seismometer. We suggest that post-spreading magmatism caused these high-velocity zones. A third high-velocity zone, showing a distinctly large velocity gradient, is revealed near the continent-ocean boundary (COB). This indicates upper mantle upwelling and/or exhumation right at the COB, despite recent unsuccess in directly sampling these deep materials in the SCS.

Abstract. Micro Small and Medium Enterprises are one business model with small to medium capital. Money turnover in the Small and Medium Micro Enterprises business is quite fast, because generally they do retail business. The selling price of the product and its quality compete with each other, therefore a proper strategy is needed so that they can still get added profits. One way is to optimize the production process by maximizing profits. By taking a case study on the Micro Small and Medium Enterprises business that produces clothing, profits can be increased through operational optimization of production processes using linear programming and sensitivity analysis. From the results of the sensitivity analysis, an increase in the value of profits was obtained from 24% to 33%. The contribution of this research is to micro small and medium enterprises in the garment industry, it can be applied to be able to make plans to increase profits.

Abstract
Natar hot spring is one of the unique hot springs in Lampung. These springs are far from volcanoes but have geothermal manifestations so researchers wonder what geothermal systems are from these springs? Before discussing the geothermal system in Natar, the researcher wanted to know the distribution of hot water under the surface of the Natar hot springs. The method used to determine the distribution of hot water is the magnetic method using a gradiometer tool. This research is still ongoing so the results cannot be concluded.

Abstract
We implemented sparse directs solver in our TE-mode magnetotelluric inversion program. The two dimensional inversion program was built using edge finite element modelling. The use of edge finite element could improve the accuracy of magnetotelluric modelling. However, solving the sparse linear system of edge finte element is very time consuming and this would affect the time required to solve the inversion problem. Using the sparse direct solver to solve the linear system in edge element modelling could make the inversion faster and more efficient.

Abstract
Nurses can have a risk when interacting with patients, one of which is contracting or transmitting an infection. Infection is the entry and development of microorganisms in the body that cause pain accompanied by clinical symptoms both locally and systemically. Injury from needle puncture to health workers is a significant problem in the institution of health services today it is estimated that more than one million needles are used annually by nurses. The purpose of this study was to analyze the relationship between the practice of safe injections and the incidence of needle stick injuries in Kendari City Hospital. This study used observational analytic with cross sectional approach with a sample of 45 people taken by proportional random sampling using the chi square test. The results showed that there was a relationship between the practice of safe injections (X2hit = 7.487, p value = 0.006) with the incidence of needle stick injuries in Kendari City Hospital. The conclusion of the study was that the lower the application of safe injecting practices, the higher the chance of the occurrence of needle puncture injuries. It is recommended that the Hospital can provide socialization about safe injections to the implementing nurses and take action according to the SPO and the existence of training and supervision from superiors on an ongoing basis.

Abstract
One of the developing industries in Kediri is the tofu industry with approximately 121 industries in 2018. The location of the tofu industry is spread in several villages in Kediri. The development of the tofu industry is followed by the problem of wastewater effluent. According to the Kediri Environment Office, only 1 tofu industry had a permit of wastewater management in 2018, another has wastewater treatment but did not have permits and the rest did not have wastewater treatment. The Government of Kediri has not monitored the tofu wastewater maximally yet, so that the waste has a potential to cause pollution to water bodies. The aim of this study was to design a Waste Water Treatment Plant (WWTP) as an alternative to solve the tofu wastewater problem in Kediri. In this study, step of design was started by collecting data including tofu industry categories, determining alternatives of WWTP process, designing WWTP for factories with a production capacity of more than 200 kg/day and less than 200 kg/day, technical drawing, and calculating the costs required for the construction and operation of WWTP. Based on the design, the tofu WWTP consists of neutralization tank, anaerobic digester, and anaerobic filter. The processing unit has the advantage of being able to reduce potentially environmental pollution and provide benefits in the form of biogas from the anaerobic process. The investment fund for a WWTP with a production capacity of less than 200kg/day is IDR 128,158,000 while for a production capacity of more than 200kg/day requires an investment fund of IDR 378,376,000.

Duck is one of the food sources consumed by Indonesians from all levels as an enormous source of protein and fat for all ages. This research aims to recognize the interaction between a variety of ginger (Zingiber officinale) in both automatic feeder and manual by observing the level of glucose and cholesterol. The research applied RAL experiment design using 2 x 2 factorial pattern with factor A as providing Zingiber officinale and Zingiber officinale Rosc. while factor B as using automatic feeder and feeding manually with 3 repetition. The treatments used in the experiment are J1P1 (feed + Zingiber officinale 2% + automatic feeder), J1P2 (feed + Zingiber officinale + manual feeder), J2P1 (feed + Zingiber officinale Rosc. 2% + automatic feeder), J2P2 (Feed + Zingiber officinale Rosc. 2% + manual feeder). The subject of the research was DOD (Day Old Duck) from Magelang which was raised since three days old up until the age of 8 weeks for sampling. The result of the research showed no interaction between feeding the ducks with Zingiber officinale or Zingiber officinale Rosc. using both automatic and manual feeder to the level of glucose and cholesterol in the ducks- blood (P > 0.05). The highest level of glucose came from J2P2 which consisted of feed + Zingiber officinale Rosc. + manual feeder reaching an average of 186 mg/dl. Meanwhile, the highest level of cholesterol was also reached in J2P2 with an average of 125.67 mg/dl.

Abstract
There is low utilization of plastic waste in Indonesia and only a fraction of plastic materials goes back into production processes through re-use and recycling practices. The human dependency on plastic consumption increasing each year. It is lightweight, flexible, relatively inexpensive, and durable and used by several purpose to carry the different daily needs from grocery bags to 3D printed rocket nozzles. The main objective of this paper is to increase the knowledge regarding the factors that inhibit demand for recycled plastics and to identify critical barriers for plastic recycling process of Indonesia. The barriers, which identified, include the lack of both supply and demand of recycled plastic attributed to the fragmented market of secondary materials. The main hotspots identified are the low demand due to price considerations, insufficient traceability and general design deficiencies in the recyclability of products.

Abstract
This paper is review of Dairy related income in Nepal throughout several research paper that had published in some national and international articles, Nepal is one of Agriculture based country and still least developing country. It has huge potential to grow in various way one of the sector is Dairy Industry. Huge demand of dairy product like Milk, yoghurt, cheese. Dairy Industry of Nepal is lack of good quality and not modernized and its cause huge loss in economy of Nation. After reviewing the article it is suggested that Nepal has wide range of economic potential in Dairy Industry but due to lack of several modernization and poor planning implementation it has bad performance till now.

Abstract
The purpose of this study was to find out how the Muncar Sub-district fishing community handled poverty throughout their lives. This research is a qualitative descriptive study using in-depth interviews conducted on 110 respondents from Fisher. The results of this study find out the main reason for being a fisherman because this work is derived from generation to generation, this is due to the low education of fishing families with a majority of income of 1-10 million per year. This amount is not a large number and makes this profession attractive to fight for, therefore the priority of primary needs is higher than secondary, awareness of the use of insurance is quite low, low post-harvest financial planning and difficult capital gains cause fishermen to obtain capital through debt and the majority of fishermen have loan. The loan source is very friendly and many are chosen by fishermen with a loan system to ship owners because it will make it easier for fishermen to make payments by deducting the honorarium as a crew

Abstract
Aroma based electronic nose recognition instrument develops for medical needs. This instrument is expected to be able to detect diseases in the body, through urine, blood, breath, sketch, sweat and human feces. This is a new challenge for instrument enose, especially for recognizing type 2 diabetes mellitus (DM). Some previous studies applied statistical methods using the time domain, such as using maximal, minimal, standard deviation, variance and means. Each sensor uses only 1 statistical feature. Enose has not used more than 1 statistical feature. This article discusses the effect of the number of features included in the process of recognition of the results of the introduction. Enose uses 4 polymer gas sensors, then calculates the statistical characteristics of the changes in the gas sensor resistance. This results in a feature matrix. The next process is calculating feature extraction using the PCA (Principle Component Analysis) method and clustering using the FCM (Fuzzy C Means) method of the feature matrix. Enose uses characteristic variations ranging from 2 traits, 3 traits, 4 traits and 5 traits. The results of the introduction show that, enose using 3 characteristics has a high accuracy of 83.3%.

Abstract
The need for aroma recognition devices or often known as enose (electronic nose) is increasing. In the field of health, enose is able to detect early type 2 diabetes mellitus (DM) from urine aroma. Enose is an aroma recognition tool that uses a pattern recognition algorithm to recognize urine aromas from diabetes mellitus patients based on input signals from gas sensor arrays. The need for portable enose devices is increasing, because of the increasing need for real-time needs. This has a large impact on the selection of the number of gas sensor arrays in the enose. This article discusses the effect of the number of sensor arrays used on the results of the introduction. Enose uses a maximum of 4 sensors, with a maximum feature matrix. After that, the characteristic matrix enters the feature extraction of PCA (Principle Component Analysis) and clustering using the FCM (Fuzzy C Means) method. Variations in the number of sensors consist of 1 sensor, 2 sensors, 3 sensors and 4 sensors. The sensor used consists of MQ2, MQ5, MQ6 and MQ8. The results of the introduction show that, enose using 2 sensors has a high accuracy of 98.3%.
