Abstract

Garbage is a part of human life. Garbage is an object/waste that is not used. Garbage should receive serious attention and handling. However, due to the lack of understanding of the community and the government, as well as the lack of cost and income of the majority of the community, this waste problem has become neglected. At present most of the people have learned about the adverse effects of waste, including causing floods, diseases, and odors that can interfere with life, but this is not balanced by the behavior of the community itself so the purpose of writing the article is as a form of community service by inviting the community in Kampung Melayu RW.02, Batu Besar Village, Nongsa District on how to deal with both organic and inorganic waste by providing trash bins, providing socialization and modules in socialization activities

Abstract

As we study higher education, the least we can do is contribute back to society. We need to apply the rule of ? Give and Take?. Inspired by our lecturer giving us support and encouragement. We, eight people, decided to visit an orphanage called ?Panti Asuhan Istana Yatim Al-Jufri? which located at sekupang as our class?s devotion target is in this area. We donate things such as food & drink, snack, stationery stuff and teaching the kids mandarin language based on our ability. We believe that even though we are not giving them much, but it?s better than no. right ? Seeing the kids smile and laughing is the best satisfaction we get from this implementation program. It may sounds like there?s no innovation, we do admit that. However, we thought that the outcome we get is far more important than innovation that we don?t even have any ideas.

Abstract

This study examines the lack of adequate knowledge of residents of Batam Block 3 Lubuk Baja about online taxes. The purpose of this study is to provide an introduction to online tax and to encourage citizens of Block 3 to participate in paying taxes as an Indonesian citizen (WNI). The data collection process was carried out by observing the needs and constraints of local residents, as well as through interviews with the head of RT 01 Block 3 (Mr. Irwansyah). The material obtained from interviews was transcribed and analyzed. The results of the analysis raised 2 themes discussed here: social support and the goal of participation. The study of these two themes is very useful for understanding how to optimally increase the knowledge and motivation of citizens in carrying out online tax payments.

Abstract

Having unlimited needs and wants, humans as economic beings will struggle to meet their needs. In this modern era, shopping for human needs and desires has become easier to do with the availability of various stores and malls to online retail. This ease of shopping has increased interest in shopping for unlimited material needs and indulges Indonesians to continue making purchases in order to develop uncontrolled compulsive buying behavior. Therefore the authors aim to examine the effect of materialism on compulsive buying mediated by the use of credit cards and impulsive buying. The object of this research is credit card users in Batam. Sampling was done by giving a google form questionnaire to credit card users in the city of Batam. Demographic data of respondents were then analyzed using IBM SPSS Statistics version 25.0 and analysis of the effect of independent variables on the dependent variable was carried out using Smart PLS version 3.2.8. The results of this study indicate that the variables of materialism, use of credit cards and impulsive buying have a significant effect on compulsive buying.

Abstract

The purpose of this study is to analyze the effect of perceived usefulness, perceived ease of use, risk, trust, and attitud e toward using on interest in using the Shopee application. The types that we use for research are qualitative and quantitative. This research was conducted with a number of respondents as many as 168 respondents. The sampling technique used was the cluster & stratified, dispropotional, random sampling technique. Hypothesis testing using multiple linear regression. The results showed that trust in conducting transactions and behavior in transactions can affect the interest in using the Shopee application in Batam city and other factors do not affect people's decisions in the city of Batam. The test results of the coefficient of determination on the adjusted R2 value show a value of 0.56 which means the independent variables in the study show a value of 56% and the other 44% is explained by the outside variables.

Abstract

Abstract: Oral biofilm containing microorganisms is responsible for various oral infections and inflammatory diseases. Bioactive compounds found in rambutan peel extracts (Nephelium lappaceum L)  has antibacterial properties. Nanoparticle sizes were known to have the greater capability as an a antimicrobial. This study aimed to compare the efficacy of rambutan peel extracts (RPEs) in micro-particles with nanoparticles against oral bacteria, i.e. Streptococcus mutans and Staphylococcus aureus. This was a laboratory experimental study with a post-test-only design conducted by using RPEs in microparticles (62.5 mg/mL and 250 mg/mL) and nanoparticles (26.5 mg/mL). The particle sizes were measured; the active compound screening was carried out with gas chromatography-mass spectrometry (GC–MS); and the antibacterial activities were tested with the disc diffusion method. The particle size distribution for RPEs with microparticles was measured at 2489 nm, whereas the nanoparticle at 7.491 nm. The GC-MS results demonstrated that both microparticles and nanoparticle RPEs contained oleic acid, hexadecanoic acid, and decanoic acid. A higher percentage of oleic acid was found in nanoparticles of RPEs. There was a significant difference between microparticles of RPEs of 62.5 mg/mL (12.83±1.532) and nanoparticles (16.25±1.529). This study demonstrated that inhibitory power increased along with the elevation of RPEs’ concentration as the number of chemi-cal components intensified. The ANOVA and post-hoc Tukey HSD test showed significant differences in the effectiveness of RPEs in nanoparticles groups compared to microparticles 62.5 mg/ml against S. mutans (p<0.05). and  S. aureus (p<0.05). In conclusion,  RPEs were more effective in inhibiting Staphylococcus aureus than Streptococcus mutans.Keywords: nanoparticles; rambutan peels; Nephelium lappaceum L; antibacterial activity; Streptococcus mutans; Staphylococcus aureus

Abstract

Currently, the process of washing clothes is a commonly process that carried out in a household. To save human energy and washing time, a washing machine is used. There are a lot of washing machine models on the market, but in general the existing washing machine have standard functions, use electrical energy, quite expensive, and use materials that are less environmentally friendly. Based on these various shortcomings, it is necessary to design an innovative washing machine. The method used in this research is the concept of product design starting from seeing the needs to develop the desired product concept until making a product prototype. The washing machine designed in this study can be used to wash all types of clothes weighing 3 kilograms and is equipped with clothes drying device with a capacity of 20 clothes that rotates during the washing process, so it will speed up the drying process. In addition, the materials used come from secondhand goods, so the price is economic. This washing machine is not designed use electrical energy but kinetic energy, so it is environmentally friendly and can be also used as an exercise tool that can the user's body keep healthy and ergonomic when used.
