Abstract

New opportunities to automate everyday devices such as pet feeding have emerged as a result of the use of the Internet of Things (IoT). The focus of this research is the development of an Internet of Things-based Cat Feeder that utilizes the Blynk platform, Kodular, and sensors. Blynk enables remote cat feeding settings through an application that has an easy-to-use interface. Kodular is used as a visual application development platform in this research, allowing application creators who do not have a deep programming background to easily create user interfaces. Sensors integrated in the system collect data on the cat's behavior and diet. This allows owners to better monitor and manage their cat's diet. During the development process, Blynk was used to incorporate remote control, Kodular was used to create the user interface, and sensors were used as data input. The results show that this solution makes feeding cats easier and gives owners better control over the amount of food their pets consume. The no-code/low-code approach used in the development of the app is an advantage of this research as it allows the app to be more accessible to a wide range of users. By using sensors, cat health can be better monitored and owners can better manage their cat's food needs.

Abstract

Tourism is one of the destinations for tourists to visit a city. Usually, to visit a tourist spot, individuals check the ratings of the place through Google reviews. In addition to ratings, some people also read reviews to assess the quality of the tourist spot. However, if the reviews given do not match the rating, there is a need for sentiment analysis to identify positive and negative reviews. This study takes a case study from Batam city, namely Mega Wisata Coastarina Batam. The method used in this research is Naive Bayes. Naive Bayes is chosen for its popularity in classification methods with good accuracy. Based on the research results, there are more positive sentiments than negative sentiments, namely 200 positive sentiments and 141 negative sentiments. The testing results of the research show the performance of sentiment analysis using the Naive Bayes method, with an F1-score accuracy of 69.49% and a margin of error of +-7.67%. The precision is 71.00% in positive predictions and 67.39% in negative predictions. The recall value is 75.53% for positive predictions and 62.09% for negative predictions. The F1-score results are 86.06% for positive predictions and 64.63% for negative predictions.

Abstract

The Public Housing, Settlements and Parks Service (Disperkim) is an agency within the Batam City Public Housing, Settlements and Parks Service. As a document recorder of incoming and outgoing letters, Disperkim is expected to be able to provide administrative services related to conveying information, recording payment data to occupant data and low-cost housing data itself. Currently Disperkim still uses manual methods to manage data, namely with Microsoft Excel. This has an impact on the process of incoming and outgoing mail. Reporting data to leaders who still use manuals is often a problem in correspondence. So we need a system that can help admins in recording letters. This system was built using the PHP programming language and uses the waterfall method and MySql as the database. The aim of this research is to assist management in managing data in the Batam City Public Housing, Settlement and Parks Department and provide easy access to web-based incoming and outgoing letters. The advantage of this system is that it can be accessed anywhere as long as it is connected to the internet, and the existence of a database makes this system better in terms of cost compared to the system implemented previously.

Abstract

Nowadays people have trouble farming, because of the limited of spots, so Hyrdoponic was invented, hydroponic is an agriculture technique that replaces dirt as a planting medium with a water-based nutrient solution. In the hydroponic process, every farmer needs to monitor some parameters like TDS Rate, Temperature, and pH in most cases people like to use the old method of monitoring, some problem that we got from the old method is, farmers need to bring measuring tools for every parameter, we will create a monitoring system based on Arduino that farmer can access from distances with using platform name Blynk by internet, for research we using the waterfall method. The result of the research is a monitoring system with Arduino that can connect to a smartphone with the Blynk app on the Internet. We design the UI as simple as possible for farmers that not good at technology can use it easily, the goal of this research is make a product that can monitor hydroponic water tank, the hope we can make monitoring process being fast and easy .

Abstract

growth and evolution of the world of technology is increasing rapidly, especially in computer and smartphone technology which is no longer for digging up information but has utilized technology to enter the business world in the form of applications such as virtual enchancement. AR is a merges of the future physical then digital worlds by using 3D objects that can be designed with supporting software are useful for designing house as three-dimensional object that are used by property businesses in house sales to make it easier for eachother to interact where seller still sell manually by distributing several brochures and buyers lack the time to visit the location on person. the reason of this ponder is to plan home sales apps that is useful for a lot facilitating interactions between home sellers and buyers. In this research, several house designs were made using sketchup and then using unity to connect to the display and included in unity to create an application in the form of function buttons to make it easier to use and combine 3D objects with markers. Based on the designed test, the application can function and display 3D objects correctly.

Abstract

The increasing use of technology in the industrial world has another significant impact on the occupational health and safety of workers. A work environment that is too noisy can lead to counter-productive, unhealthy, and upsetting situations. Based on the measurement results in the extruder machine area obtained with an average value of 96.62 dBA, this value exceeds the standardized Threshold Value (NAV) of 85 dBA for 8 hours of work. From the results of interviews conducted with several workers, many workers complain of hearing loss such as ringing in the ears, decreased hearing resulting in lack of concentration of the interlocutor. This study aims to analyze the effect of noise on hearing loss of PT Volex Indonesia workers. The population used in this study is all operators who work in the extruder machine area during the PVC manufacturing process. The data analysis method in this study uses quantitative methods that are processed using computer technology, namely the SPSS 21 program. The result of the regression coefficient of 19.651 means that for every noise value plus 1, hearing loss will increase by 19.651. So this regression coefficient has a significant effect so that noise affects hearing disturbance and from the results of the sig (2-tailed) correlation test 0.009 < 0.05, there is a strong correlation with the pearson correlation value of 0.771. It was concluded that there is an influence of noise on hearing loss.

Abstract

In the midst of the current manufacturing industry competition, companies are required to maintain the quality of their produced products. PT ABC is one of the manufacturing companies engaged in the production of electronic and medical products. In this study, issues were identified in the molding department, which had a high number of black dot defects in Housing Bottom products. The objective of this research is to determine the factors causing the decline in the quality of Housing Bottom products and to identify improvement efforts for the black dot defects. This study uses a fishbone diagram to analyze the factors causing black dot defects and the DMAIC method to determine improvement efforts for the causes of black dot defects. The research findings using the fishbone diagram identified that the cause of black dot defects is a machine factor related to nozzle temperature. Therefore, the improvement efforts conducted using Design of Experiment involve setting the nozzle temperature at 290°C and the metering section temperature at 290°C, resulting in low black dot defects.
