Abstract

CV. Sapi Nusantara Jaya is a joint business entity of members of the cattle and beef cattle fattening business and beef cattle engaged in the feedlot sector. In the process of shipping goods, of course, there is evidence of the issuance of goods in the form of travel documents. This travel document is something that must be included in the process of sending goods so that things do not happen that can harm one or both parties. At CV.Sapi Nusantara Jaya currently still using the conventional way of working. That is still using handwriting and still using forms made of paper, which are likely to be damaged or lost tend to be more vulnerable. The author will do the design of the document processing system on the CV. Sapi Nusantara Jaya starts with proof of delivery of goods (goods have been received). This system is designed using PHP (Hypertext Preprocessor) as the programming language and MySQL (My Structured Query Language) as the database, using the SDLC (Sequencial Development Life Cycle) method. It is hoped that this system will maximize admin staff so that the delivery of information and data collection can run effectively. The result of this research is that the design of the document archive is built using the PHP programming language and the MySQL database can make it easier to carry out the data collection process and computerization process.

Abstract

This web-based designing and building of the Environmental Planning Licensing Informastion System of Kendal Regency was created to help and improve the licensing services in the Environmental Management Field of the Environmental Service of Kendal Regency. The purpose of this study was to create a web-based data processing information system aimed at administrator and officers of the Environmental Service of Kendal Regency and also visitors or permit applicants to observe their submitted application.This research used data collection methods by observation, interviews, and literature studies as well as system development methods using the Linear Sequential Model or Watefall Model. The Waterfall Method has some steps, namely data collection, analysis, design, implementation / coding, testing, operation, and maintenance. The reason for choosing this method was the method must be carried out systematically or sequentially and each step has its own focus, so that the system can be developed based on the wish. The system design method used is the Data Flow Diagram (DFD) method.The result of this study is an environmental planning licensing informastion system that manages submission data, licensing data, submission requirements, checklist requirements, photo data, message boxes, and visitor pages with a search system to help the applicants finding information relate to the processing of the file that has been submitted.

Abstract

Yogyakarta is one of the leading tourist destinations in Indonesia with diverse attractions, ranging from cultural, historical, to natural attrac-tions, which often pose challenges for tourists in determining tourist destinations according to their preferences. This study aims to develop a recommendation system for the best tourist destinations in Yogya-karta City through the integration of the Multifactor Evaluation Pro-cess (MFEP) and K-Means Clustering methods. MFEP is used to rank destinations based on five main criteria, namely location, accessibility, facilities, cost, and uniqueness, with weights obtained from the results of tourist preference surveys. The ranking results are then analyzed using K-Means Clustering to group destinations into three categories of tourism potential, namely high, medium, and low, based on addi-tional parameters such as strategic location, number of attractions, and number of visitors. The results of this study prove that the integration of MFEP and K-Means is able to produce fast, accurate, and informa-tive recommendations, and can be used by tourists and tourism manag-ers in strategic planning and decision-making. System functionality testing using the black box method shows that all features run as need-ed, while clustering quality testing using the Silhouette Coefficient method produces very good clustering quality with an average score of 0.9552.

Abstract

This study explores the use of graphene-based nanofluids in enhancing the performance of solar-powered desalination systems. A laboratory-scale desalination system was developed to simulate the evaporation process, powered by solar energy, with the integration of graphene-based nanofluids to improve thermal efficiency. The experimental setup measured evaporation rates, energy consumption, and temperature profiles under varying solar radiation conditions (400–800 W/m²). Results revealed that the system with nanofluids demonstrated up to a 35% increase in evaporation rates compared to the baseline system without nanofluids, indicating enhanced heat transfer properties. Moreover, energy consumption was reduced by up to 20%, highlighting the improved energy efficiency of the system with nanofluids. The system with nanofluids exhibited higher temperatures in the evaporator, confirming more effective thermal utilization. Statistical analyses, including t-tests and regression analysis, confirmed the significant impact of nanofluids on both evaporation rates and energy consumption. This study demonstrates that graphene-based nanofluids offer a sustainable and energy-efficient solution for solar-powered desalination, particularly in areas with abundant solar radiation. The integration of nanofluids not only enhances the efficiency of the desalination process but also reduces operational costs, making it a promising alternative for addressing water scarcity in a sustainable manner. Further research is needed to optimize nanofluid formulations and assess their long-term feasibility for large-scale applications.
