Abstract

The use of information and communication technology in the field of government is an important thing to support an electronic-based government system or what is commonly called e-government. Responding to the instruction, the Investment and Integrated One-Stop Service Office (DPMPTSP) of Badung Regency in carrying out its duties and responsibilities utilizes the application of information technology by using web-based and mobile applications. The service system is called licensing services or abbreviated as laperon. This study uses the NIST SP 800-30 framework in evaluating risks in the four systems and uses the CMMI framework to determine the maturity level. The results of the risk identification show that the licensing service information system has 4 high-level risks, 12 medium-level risks and 29 low-level risks. The results of the maturity level assessment questionnaire show that the licensing service system has a maturity level gap of 1. Recommendations are given to minimize the identified risk threats and achieve the expected maturity level based on the NIST SP 800-53 revision 4 guidelines.

Abstract

Bali Province is one of the areas that has abundant renewable energy potential. Through increasing the role of renewable energy in the national energy mix which is a government program, which aims to reduce the use of non-renewable energy and open community participation in utilizing renewable energy in Bali Province. To overcome these problems, an analysis of the investment costs of developing renewable energy plants in Bali Province in 3 scenario modeling was carried out. In this scenario modeling is carried out to determine the investment cost of developing renewable energy plants in Bali Province in the 2024 - 2045 time span. The results of this study show that renewable energy investment costs in the optimistic scenario require investment costs of 264,12 Million USD in 2024 increasing to 2.078,35 Million USD in 2045 with total investment costs during the modeling period of 46.477,10 Million USD. The moderate scenario requires investment costs of 264,12 Million USD in 2024 increasing to 1.186,30 Million USD in 2045 with total investment costs during the modeling period of 27.362,52 Million USD. The pessimistic scenario requires investment costs of 264,12 Million USD in 2024 increasing to 986,80 Million USD in 2045 with total investment costs for the modeling period of 20.817,04 Million USD.

Abstract

This study discusses the application of fuzzy logic control systems for maximum power point tracking (MPPT) in wind turbines, focusing on the system's performance. Fuzzy logic control is used to optimize the operation of wind turbines by adjusting the turbine's rotational speed based on input variables such as wind speed and torque, which are often difficult to model mathematically with high accuracy. By employing a fuzzy approach, the system can handle uncertainties and nonlinearities in the wind turbine's operational environment, thus providing more adaptive and responsive control to changes in wind conditions. Experimental results show that the fuzzy control system can improve the power output efficiency of wind turbines by maximizing the generated power under varying wind speeds. The system's performance is evaluated based on parameters such as power output stability, response time, and accuracy in reaching the maximum power point. Simulation and experimental results reveal that the fuzzy control approach offers superior performance compared to traditional control methods, making it an effective alternative for optimal wind turbine operation.

Abstract

This study aims to evaluate the information technology security system at the Unit Sumber Daya Informasi (USDI) of Udayana University using the COBIT 5 framework, focusing on the APO (Align, Plan, and Organize) and DSS (Deliver, Service, and Support) domains. The use of information technology at Udayana University is crucial to support both academic and non-academic activities, making information management and security a priority. The COBIT 5 framework is used to assess IT management capabilities and identify gaps between the current and expected conditions. The research methods include questionnaires, interviews, and observations with unit leaders and staff at USDI. The evaluation results show that the APO 13 (Manage Security) and DSS 05 (Manage Security Service) subdomains have reached level 3 (established process), which means these processes have been well implemented. However, there is potential for improvement to level 4 (predictable process). This study provides recommendations to improve information security management, including establishing of an information security division, enhancing human resource competencies, preparing SOPs, and conducting regular internal monitoring and audits. With these improvements, it is expected that USDI Udayana University can optimally manage and protect the IT system, supporting institutional goals more safely and efficiently.

Abstract

Telkomsel Bali Nusa Tenggara is one of the regions owned by Telkomsel. In each region, there is a General Affair division that is responsible for managing the company's operational needs. In supporting existing activities, the General Affair division already has an information system. However, there are still business processes that are carried out manually and there are no information system design guidelines for the General Affair division. Therefore, it is necessary to design enterprise architecture using TOGAF ADM with eight phases consisting of Preliminary Phase, Requirement Management, Architecture Vision, Business Architecture, Information System Architecture, Technology Architecture, Opportunities and Solutions and Migration Planning. The purpose of this research is to create a division architecture design that is in accordance with the company's vision and mission. Data was collected using observation method, interview method and document analysis. The results obtained are the target architecture design and blueprint.

Abstract

The Three Nusa Islands consist Nusa Penida, Nusa Lembongan, and Nusa Ceningan are facing increased energy demands due to growing tourism, population, and economic activity. Biomass energy, as a renewable and locally available energy source, presents a viable solution to help meet the island’s sustainable energy needs. This review explores the potential of biomass energy in the region, focusing on the availability of biomass feedstock, technological feasibility, environmental impact, and social acceptance. The study is based on secondary data from government reports, academic journals, and regional statistics, aiming to contribute to the development of decentralized and sustainable energy strategies in Eastern Indonesia.
