Abstract
PicsArt is an image and collage editing application that allows its users to edit or create pictures and then share them in a social networking community. PicsArt users can create or edit interesting pictures based on their preferred theme. This study was aimed to utilize the PicsArt application to disseminate the Standard Dictionary of Indonesian (KBBI) and to introduce appropriate terminologies to the community in social networks. To date, many people do not know the appropriate terminologies or name of objects, for example the word kapak with kampak. Using PicsArt application, an image was displayed and underneath, the word kapak and kampak were written accompanied by green and red checklists. The green checklist indicated the correct terminology and the red checklist symbolized the incorrect one. After that, an explanation of the definition of the term was given. The method used in this study was qualitative descriptive. The results of this study indicated that the PicsArt application facilitated community members to capture the message conveyed through the images. The modified images made community members understand the meaning relevant to KBBI and increasingly recognize the correct terminologies.

Abstract
Referring to the Government Regulation of the Republic of Number 79 of 2014 on National Energy Policy, the Indonesian government is committed to developing a renewable energy mix by 23% in 2025. However, the realization is still below 5%. This prompts the Garut Regency government to jointly commit to developing renewable energy by utilizing domestic waste for electricity generation. The purpose of this study is to design a strategic partnership in the development of a waste-to-renewable energy in Garut and analyze its social impacts. Data were obtained from Garut Environmental Office and Garut Bureau of Statistics and through interviews with related stakeholders. The results showed that the governments limitation in technology can be overcome by the involvement of the private sectors (investors from South Korea and Japan). Strategic partnership can help the Garut government realize their waste-to-renewable project.

Abstract
Greywater from domestic activities on the riverbanks settlement in Indonesia usually channeled directly to the drainage or to the river. It will be decrease the water quality. The aims of the research are to analyze the pollutant load due to greywater from settlement in banks of Ciliwung River segment 2 and responses of society sanitation habits. The research was conducted at 6 villages are Babakan Pasar, Sukasari, Baranangsiang, Cibuluh, Kedung Badak, and Sempur. Water samples were taken from the drainage channel in the morning and evening, which are considered to represent the peak hours of greywater. Sampling was conducted in May, June and July 2018. Pollutant load based on BOD level in the drainage channel ranges from 4,903.19-132,804.33 kg/day. This condition shows the high tendency of pollution due to greywater domestic activities and absence of greywater treatment in residential areas. Almost 50% of the community understand the importance of the need for wastewater management. Community awarness for sanitation habits such as environment community service, maintenance and handling waste in drainage, periodic septic tank desludging, and greywater disposal to drainage are needed. The conclusion is that greywater treatment in riverbanks settlement is really needed to be applied.

Abstract
Situ Parigi is located in Parigi Lama Village, Pondok Aren District, South Tangerang City. Based on the water quality measurements of Situ Parigi, BOD parameter has the highest concentration. This indicates that the type of waste that enters this water body is dominated by organic waste produced from domestic activities around it. The purpose of this study is to determine the pollutant load capacity of BOD in Situ Parigi. Pollutant load capacity is calculated using formulas in Minister of Environment Regulation No. 28 of 2009 concerning Capacity of Lake Water Pollution and/or Reservoir Load. Situ Parigi has an area of 4 Ha, an average depth of 0.98 m, a debit of 0.023 m3/sec and a hydraulic residence time of 18.25 days. Based on the calculations results, the pollutant load capacity of Situ Parigi is 3,169.81 kg/year but must accommodate a load of 20,553.15 kg/year. These results show that the pollution that occurs in Situ Parigi has exceeded its capacity. Control strategies such as dredging work and the construction of communal wastewater treatment plants could be carried out in an effort to reduce the occurring pollution levels.

Abstract
Previous sudies on commercial sex workers reported that the number of commercial sex workers spreading throughout Denpasar city and its surroundings is 250 persons and 14% of them had been infected with HIV/ AIDS (Human Immunodeficiency Virus/ Acquired Immune Deficiency Syndrome). However, referring to the data in the City Health Service of Denpasar, the number of direct commercial sex workers throughout Sanur area in 2017 is 450 persons. Such number confirms that the risk of sexually transmitted infection among the direct commercial sex workers in the area is intensely high. Condom use is seemingly ruled out. Thus, by the present study, an explorative investigation is carried out to explore more about the condom use among the direct commercial sex workers in Sanur. The study applies qualitative research design. A purposive sampling technique was implemented in selecting 15 informants. The 15 informants included the direct commercial sex workers, pimps, and customers. These informants were provided with in-depth interviews. The results of data analysis showed that during sexual intercourses not all the direct commercial sex workers applied the use of condoms. The leading reason was the male partners disliked the condoms in the sexual intercourse. However, it is also found that economic factor had given rise to avoiding the condom use. It should be noted well that using condoms during sexual intercourse decreases the growing number of the direct commercial sex workers.

Abstract
The efficiency of ethyl-p-methoxycinnamate and its derivatives as corrosion inhibitors of iron corrosion in acid environment has been studied to find the relationship between molecular structure parameters with the efficiency of corrosion inhibition. The MP2 perturbation theory was applied to calculate molecular structure and electronic parameters. Computational and experimental corrosion inhibition efficiency show that the electronic properties of molecules, including the orbital molecular frontier energy (HOMO and LUMO energy), ionization potential, electron affinity, electronegativity, softness, hardness, number of electron transfer from inhibitor to metal, and interaction energy have a strong relationship with inhibition performance. Furthermore, Fukui function obtained from natural bond orbital analysis was employed to study the interactions between inhibitors with iron metal in more detail. The presence of heteroatom and electron donor groups within the frameworks of inhibitors has a significant effect on corrosion inhibition performance.

Abstract
This paper discusses the complementary of the Quaternion method and the Boole method on the IMU sensor to calculate the orientation angle of the Stewart Platform. Validation of orientation angles The Stewart platform is very difficult to do using manual measuring devices, so it requires an IMU sensor to calculate the orientation angle. The IMU sensor consists of three types of sensors, namely the accelerometer, magnetometer, and gyroscope sensors. The Quaternion method is used to calculate the pitch angles and the roll of the accelerometer sensor, and calculate the yaw angle of the magnetometer sensor. The Boole method is used to calculate the pitch, roll, and yaw angles of the gyroscope sensor. Next, the orientation angle of the accelerometer and magnetometer is combined with the orientation angle of the gyroscope using complementary. The test is performed in six repetitions with angular parameters: 5, 10, 15, 20, 25, and 30 degrees. Overall, the pitch angle has an average of error percentage of 2.31%, roll angle has an average of error percentage of 1.98%, and yaw angle has an average of error percentage of 1.63%. The measurement results of the orientation angle of the Stewart Platform using the IMU sensor show that the complementary of Quaternion and Boole methods on the IMU sensor is quite feasible to be used as measuring instruments for the orientation angle of the Stewart Platform

Abstract
Multivariate Control Charts is an effective tool in Statistical Process Control to identify either an out-of-control process or in-control process. Hotelling T2 control chart is a quite popular and widely used technique in this field. However, its performance is deteriorated when the underlying distribution of the quality characteristics is not following the multivariate normal distribution. Multivariate control chart usually recommended a procedure in the phase-in Hotelling T2 control chart although there is difficulty in interpreting the signals from multivariate control charts more work is needed on data reduction methods and graphics techniques. Basically, the multivariate control chart refers to the theory of prediction interval. Therefore, its called predictive multivariate control charts. We aim to construct what so-called predictive multivariate control chart both classical in this part in the phase-in Hotelling T2 and Copula-based ones. We argue that appropriate joint distribution function may be well estimated by employing Copula. A numerical analysis is carried out to illustrate that an Application Copula-based Multivariate control chart outperforms than bivariate control chart and others.

Abstract
Cavitation has been one of the critical issues in turbomachinery operation which often causes the reduction of service life of the components. In order to predict the service life, cavitation intensity (CI) needs to be measured accurately. In this paper, several notable developments of techniques to measure CI are reviewed briefly. Those techniques can be classified into two groups, i.e. direct and indirect measurements. For the indirect technique, a method which estimates the impact load of bubble collapse by inverse analysis is particularly elaborated. For the direct technique, a method which utilizes painting technique to quantify the actual CI is specifically presented. The advantages and disadvantages are also comprehensively discussed.
