Abstract

The Kuta Art Market, is a modern market that was recently revitalized in 2023. The building has renewable energy potential of PLTS on the roof area, when this potential can be exploited then the electricity consumption of the Kuta Art Market Building is no longer supplied by conventional power plants (PLN) but will enjoy clean energy of autonomous plants such as PLTS. The aim of this study is to identify the potential for generating electricity on the roof of the Kuta Art Market, determine the capacity of the battery as a reserve source of energy and the value of the investment. The research steps of this thesis calculate the solar energy potential in the area of the Kuta Art Market by using PVsyst software, collect the load profile of the Kuta Art Market. The next step is to compute the capacity of the PLTS - inverter then determine the battery capacity required according to the load profile of the Kuta Art Market and then determines the investment cost to build the solar power plant on the rooftop of the Kuta Art Market as well as to evaluate the potential cost savings that can be achieved by using solar energy as a primary resource. The total roof area of the Kuta Art Market is 780,455 m2 with energy potential of 166,23 kW. Based on the design results, PLTS will be built with a capacity of 61,6 kWp, with total battery capacity 3200 Ah. Total investment of Rp. 1,162,938.563 is required for the construction of PLTS, a payback period of 15 years 8 months, NPV of Rp. 204,439.887,26 and IRR of 8,06%. Based on the values above, it indicates that the PLTS project on the roof of the Kuta Art Market building is feasible to carry out.

Abstract

The Development Administration Section is an organization in the field of government in Gianyar Regency which has a work program which is to supervise the realization of the budget for each RAO (Regional Apparatus Organization) and is assisted by using the TEPRA Information System to carrying out a routine evaluation process every month, so it is important for the information system to minimize the risks that may occur. The research process uses two frameworks, namely the COBIT 2019 framework and the NIST 800-30 framework. The use of NIST 800-30 found 12 gaps out of 12 threats with 8 risks being medium and 4 risks being low. Continuing the use of COBIT 2019 resulted in calculating the highest rating value in the first process APO 13 domain with a value of 4.58, a percentage of 91%, Fully category. And the domain with the lowest percentage with a value of 3.00, the percentage is 60%, the Largely category is the second and third process APO 13 domain, DSS 02 domain, first and second process DSS 03 domain and DSS 04 domain. Next, the assessment of maturity levels produces the highest score in BAI 05 domain with a value of 4.27, level value 4 (Quantitative). And the domain with the lowest score with a value of 3.00, the level value 3 (Defined) occurs in the domain DSS 02, DSS03, and DSS 04. Next, the gap level assessment with the highest value occurs in the third process APO 14 domain with a value of 1.92 which is the level of effectiveness in using problem data that does not run smoothly according to system functionality. Based on the results of the research conducted, it is hoped that it will create a developing government and create good governance, so that in the process of developing an information system, the recommendations for improvements that have been suggested can be implemented.
