Pet owners rely on veterinary clinics to meet the healthcare needs of their pets, and yet, many veterinary clinics still manage data using conventional methods without fully utilizing digital information systems. This leads to issues such as repetitive registration, difficulties in obtaining copies of medical records, and challenges in finding nearby veterinary clinics. This research aims to address these problems by designing and developing a mobile web application for a veterinary clinic marketplace. The application consists of two main components. The front-end utilizes the React.js library based on Progressive Web Apps (PWA), while the back-end utilizes the Express.js framework. To ensure the overall functionality of the application, black box testing is conducted by the developer. Through this approach, the application is expected to assist pet owners in searching for and accessing information about veterinary clinics, viewing the services provided, and managing pet medical records digitally and easily. This research contributes to optimizing data management in veterinary clinics and enhancing the experience of pet owners.
宠物主人依靠兽医诊所来满足他们宠物的医疗保健需求，然而，许多兽医诊所仍然使用传统方法管理数据，而没有充分利用数字信息系统。这导致了诸如重复登记、难以获得医疗记录副本以及难以找到附近的兽医诊所等问题。本研究旨在通过设计和开发一个兽医诊所市场的移动网络应用程序来解决这些问题。该应用程序由两个主要组件组成。前端使用基于Progressive Web Apps (PWA)的React.js库，而后端使用Express.js框架。为了确保应用程序的整体功能，黑盒测试由开发人员进行。通过这种方法，该应用程序有望帮助宠物主人搜索和访问有关兽医诊所的信息，查看所提供的服务，并以数字方式方便地管理宠物医疗记录。本研究有助于优化兽医诊所的数据管理，提高宠物主人的体验。

Indonesia has a great opportunity to utilize new renewable energy sources for conversion to electric power. One possible use of renewable energy is solar power plants (PLTS). The average potential of solar energy in Indonesia is around 4.8 kWh/m2/day. Therefore, this study is related to the design of PLTS on the roof of PT. Geber Samudra is off the grid. The design of this solar power plant is made with the help of Helioscope software with a total roof area of 125.71 m2 and a roof slope of 20°. The potential power generated is 9.8 kWp and the total annual energy production is 15.56 MWh. It takes 28 pieces of UKSOL UKs-6M 350wp solar panels, 1 Solax X3 HYBRID 10.0 T type inverter with a capacity of 10 kW, and 6 units of 48V 100Ah batteries assembled in series. Based on the results of PLTS roof design can be analyzed that the planning of PLTS roof at PT. Geber Samudra is considered worthy because it meets the criteria of net present value (NPV) of Rp. 25.603.062 is greater than zero. The Benefit-Cost Ratio (B-CR) is greater than one which is 1.12, and the discounted payback period (DPP) is 21,8 years and is achieved at the age of PLTS with the assumption of operating for 25 years.

Reliability of the distribution system is one of the critical challenges and important indicators in the electricity power system. The indicators determining reliability are SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index). The method used to improve the reliability of the distribution system in this research is by converting two radial feeders, namely Tukad Musi feeder and Batanghari feeder, into a loop configuration.The calculation results show that before the improvement, the SAIDI value for the Tukad Musi feeder is 26.59 hours/customer/year, and the SAIFI is 1.92 interruptions/customer/year. The initial values of SAIDI for the Batanghari feeder are 18.14 hours/customer/year, and SAIFI is 1.69 interruptions/customer/year. By implementing a loop configuration through the addition of extra channels at both ends of the feeders, the SAIDI is reduced to 24.79 hours/customer/year, and SAIFI becomes 1.89 interruptions/customer/year. Further improvements are achieved by maneuvering a portion of the load, resulting in SAIDI of 21.51 hours/customer/year and SAIFI of 1.83 interruptions/customer/year.This study contributes to enhancing the reliability of the distribution system by converting radial feeders into loop configuration. The findings can serve as guidelines for planning and developing a more reliable and efficient distribution system.

The reliability of the distribution system will affect the quality of the electrical energy received by customers. The system will be said to be reliable if the disturbances and power outages that occur for a certain period of time are below the index set by an institution. The measure of the reliability of a system can be measured through the value of SAIDI (System Average Interruption Duration Index) or how long the system is interrupted and SAIFI (System Average Interruption Frequency Index) or how often a system is interrupted within 1 year and it was found that SAIFI's Tukad Musi Feeders were 1.9255 interruptions/subscribers per year, SAIDI were 26.5966 hours/customers per year and SAIFI's Batanghari Feeders were 1.6992 interruptions/subscribers per year, and SAIDI were 18.1486 hours/ subscribers per year by adding a component in the form of LBS to the two feeders will increase the reliability of the Tukad Musi feeder SAIFI of 1.8855 interruptions/customer per year, SAIDI of 26.0606 hours/customer per year and of Batanghari SAIFI feeder of 1.6814 interruptions/subscriber per year, SAIDI of 15.7925 hours / customer per year.

Indonesia's Nationally Determined Contribution (NDC) targets a 19 to 27% reduction in greenhouse gas (GHG) emissions from the energy sector compared to the business-as-usual scenario. Assuming this target applies uniformly to all provinces in Indonesia, including the power sector, a modeling analysis of Bali's power system is conducted to assess GHG emission reductions. Two scenarios are developed in the Low Emissions Analysis Platform (LEAP) to evaluate the future deployment of Bali's power system. The Business-As-Usual (BaU) scenario serves as the baseline for emission reduction in other scenarios and assumes the development of Bali's power system without emission reduction interventions. The RUPTL scenario assumes the continued development of Bali's power system in line with the electricity development plan document. Results show that the RUPTL scenario achieves a 20.89% reduction in emissions, which fulfills the regional assumption of a 19% NDC target. However, it falls short of achieving the 2030 target of 27% emission reduction.

The design of Off-Grid PV at Adidaya Workshop as an additional electrical energy supplier is based on the load requirements used for equipment and operations at the workshop. In addition to requests from the company itself, the design of Off-Grid PV is carried out to supply electrical energy to essential loads and other educational purposes. The Off-Grid PV design was carried out with the first step of field observations at Adidaya Workshop, measuring the roof area, daily electricity load profile with a Power Quality Analyzer measuring instrument, and calculating the capacity requirements of the Off-Grid PV system according to the Adidaya Workshop load. The Off-Grid PV design was carried out with 4 scenarios based on variations in solar panels and batteries. Researchers calculated the capacity of the PV system and used PVSyst software as a design simulation so that a report was obtained based on field data. In the simulation results with PVSyst, the best performance ratio is obtained which is worth 68.3% obtained from scenario 3 with a variation of 600 Wp solar panels and 540 Ah batteries and the largest yield energy output is obtained from scenario 4.

The process of sending information is currently needed to be fast and efficient. One of the solutions to meet the needs of fast information is to use transmission via a Wavelength Division Multiplexing (WDM) network. The purpose of this study is to determine and analyze the performance of WDM networks and the impact that occurs when EDFA is added and its use in PON networks. This research will utilize optisystem 7.0 software in carrying out design simulations and finding out the results of receiver power, q-factor, and BER which will then be used as a comparison in this study. The results of the analysis provide evidence that the use of WDM in the delivery process is more efficient because it can transmit several wavelengths at a time, but will have a negative effect on distance, but this can be overcome by using EDFA in WDM networks. The use of WDM-PON will expand the scope of the process of sending information. The results of this study can prove the performance in the use of WDM. In the future, it is necessary to carry out further research by adding other comparison parameters so that the results obtained will be more certain. As well as the use of the latest version of the optisystem application will help and facilitate the process of collecting information and data.

Electric vehicles are one of the solutions that can be used to deal with the problem of greenhouse gas emissions. Switching to electric vehicles can be an effective solution because electric vehicles have many advantages. However, the acceptance of electric vehicles in Indonesia depends on the opinions or sentiments given by the community. Sentiment analysis can provide a specific picture of how the sentiment or opinion given by the Indonesian people towards electric vehicles. The sentiment analysis process is carried out using the Python programming language. This research compares SVM and Naïve Bayes methods in sentiment analysis in terms of accuracy and time efficiency. A total of 717 data were used as test data and SVM correctly classified 150 negative data, 152 neutral data, and 277 positive data. Meanwhile, Naïve Bayes correctly classified 166 negative data, 143 neutral data, and 282 positive data. training time required for the SVM method is 37.42 seconds while Naïve Bayes is 0.10 seconds. Naïve Bayes is the best method in this study because of its high accuracy and fast training time.

Data demand from personal mobile devices over cellular networks is rapidly increasing. For time-delay tolerant data, the use of paid technology is inefficient. As an alternative for time-delay tolerant data delivery, opportunistic networks are emerging as an effective infrastructure-less communication model. Before it can be used as an alternative solution, it is necessary to analyze the performance of using opportunistic networks, especially the basic routing patterns used. This research analyzes the performance of routing patterns in opportunistic networks by utilizing inter-vehicle networks as mobile nodes in Denpasar City. Two basic routing patterns, namely epidemic and spray and wait, are simulated using The ONE Simulator into two scenarios including a scenario of increasing the average vehicle and a scenario of increasing the buffer size. The simulation results show that in the inter-vehicle network utilization, epidemic routing pattern is superior to spray and wait in terms of delivery probability and average latency, but when assessing in terms of overhead ratio, spray and wait routing pattern can provide lower results. This shows that the epidemic routing pattern is suitable for systems that do not care about high resource utilization.
