Abstract

In the continuously evolving digital era, the application of information technology in education has become crucial, especially for managing data efficiently and accurately. This study aims to develop a web-based attendance and grading information system at SMA Islam Al-Kahfi Somalangu Kebumen using the Waterfall method. SMA Islam Al-Kahfi, as a proactive educational institution, requires a system capable of integrating real-time student attendance management and grade evaluation to improve the quality of the teaching and learning process. This system development follows five main stages of the Waterfall method: (1) Requirements Analysis, where user needs are gathered and analyzed to determine system specifications; (2) System Design, which includes database design, user interface, and system architecture; (3) Implementation, involving the coding process and integration of system components; (4) Testing, using black-box methods to ensure all system functions work as intended without examining internal structures; and (5) Maintenance, to ensure the system continues to function well and can be updated as needed. The research results show that the developed information system successfully meets SMA Islam Al-Kahfi's needs for managing student attendance and grades. This system not only enhances efficiency in recording attendance and processing grades but also facilitates data access for teachers and administrative staff through an intuitive and user-friendly interface. End-user testing indicates that the system functions well, meets expectations, and is ready for full implementation. It is hoped that this system will make a significant contribution to improving the quality of school administrative services, particularly in attendance and grading management. The application of the Waterfall method in system development has proven effective in producing a structured, stable system that meets user needs

Abstract

Batu City is an area with abundant water spring potential. Springs are an essential part of the air supply for human domestic needs, industrial activities, and agricultural irrigation activities. Springs in Batu City are mostly used as irrigation water sources, where 15 springs spread across three sub-districts that cover Bumiaji District, Batu District, Junrejo District in Batu City use springs as irrigation water sources. The use of springs as a source of irrigation water, in addition to being considered based on quantity, also needs to be considered for its quality. The quality of water irrigation can be reviewed based on the potential alkalinity hazard (SAR) and potential salinity hazard (EC) values. The values of SAR and EC are explained using the Wilcox Graph. There are 15 springs in Batu City that have EC values in the range of 297.2 µS/cm – 748.3 µS/cm and are classified into Class C2 or moderate salinity hazard potential and SAR in the range of 0.0068 – 0.0294 included in the Class S1 classification or low alkalinity hazard potential. The results of the Wilcox Graph analysis show that the water quality of the 15 springs is in Class C2 – S1 with low alkalinity hazard potential and moderate salinity hazard potential. The results of the Wilcox Graph show that the 15 springs in Batu City that are used as irrigation sources are suitable for use as sources of water irrigation

Abstract

Delays in project implementation often occur, therefore it is necessary to carry out control on the project so that its implementation can be carried out again according to the time and cost that have been determined. Control was carried out on the Citra Dream Hotel Development Project, Block III Bintaro. The planned implementation time at that stage was 560 days. Acceleration was carried out using the Earned Value method. The yield value method is a control method used to control project costs and schedules. This method provides information on project performance in a reporting period and provides information on the predicted costs required and the time required to complete all work based on performance indicators at the time of reporting. In the Citra Dream Hotel Development Project, Block III Bintaro, the BCWS (Budget Cost of Work Schedule) value was obtained = Rp. 2,517,673,147,940.23, the BCWP (Budget Cost of Work Performance) value = Rp. 2,441,825,773,572.85, the ACWP (Actual Cost of Work Performance) value = Rp. 2,342,994,346,366.87, based on the schedule aspect, this project is delayed, this is proven by the SV (Schedule Variance) value = -Rp. 919,362,113.54 and SPI (Schedule Performance Index) = 0.97 <1. Based on the acceleration management that has been carried out to accelerate the project by adding overtime hours for 2 hours. The addition of overtime hours can save the project duration by up to 9 days

Abstract

Construction projects are closely related to the development of human life needs. To meet this, construction projects must be processed professionally with good management and weight. As one of the functions and processes of activities in project management that greatly affect the final results of the project, planning has an important role in minimizing all irregularities that can occur during the project process. Earned Value is the concept of calculating the amount of costs according to the budget in accordance with the work that has been completed. Cost and time optimization planning is carried out on the Embarcadero Bintaro Apartment Construction Project with the aim of finding out the project performance index, estimated cost and time required, providing alternative solutions to overcome the delays that occur and creating an S curve due to acceleration. The results of the calculation using the Earned Value method show that the project is not running as planned, based on the overall CPI value of > 1. Meanwhile, the SPI value in the 10th week to the 32th week has a value of less than 1, this indicates that the project is experiencing delays. The acceleration carried out to catch up with the delay is to use the crashing method with the most effective acceleration alternative to be applied, namely the addition of 2 hours of overtime to the Column work, by saving the project duration of up to 9 days and an additional cost of Rp. 80.611.591,48 from the normal cost of Rp. 104.928.799.666,42 with a duration after acceleration of 572 days

Abstract

Credit is an important instrument in improving the community's economy, providing wider access to capital through financial institutions. Perumda BPR Sukabumi is one of the institutions that offers credit programs to support local economic growth. However, until now, BPR Sukabumi does not have a computerized credit worthiness analysis system, causing the decision-making process for granting credit to be slow and at risk of errors, which can have an impact on company performance and customer satisfaction. This research aims to design and implement a decision support application for credit worthiness analysis using the Analytical Hierarchy Process (AHP) method which is expected to help credit analysts in assessing and recommending the feasibility of granting credit. The AHP method was chosen because of its ability to manage various complex, interconnected criteria in the credit worthiness assessment process, including customer profile, credit history, financial stability and proposed collateral. In this system, the weight of each criterion is analyzed and ranked for more objective and accurate final results. The result of this research is a computer-based application that simplifies the credit worthiness analysis process at BPR Cibitung. With this application, credit analysts can more quickly and accurately assess prospective customers, so that credit decisions can be made more efficiently. This AHP-based application is also expected to be able to reduce the risk of bad credit by identifying potentially high-risk customers. Thus, this application can be a useful tool for improving operational efficiency and the quality of BPR services to its customers

Abstract

Feed plays an important role in providing essential nutrients to livestock, meeting their basic needs for survival and productivity. Feed supply difficulties also occur in East Nusa Tenggara Province more specifically in Ngada Regency, Bajawa District. An effective solution to overcome the challenge of feed availability is to incorporate alternative feed ingredients. One type of agricultural waste that is commonly found is banana stems. Banana trees are widely found in tropical areas such as Indonesia, especially in areas that have many banana trees such as the Bajawa area. The cutting down of banana trees for fruit will produce more waste, such as leaves, stems, stumps, and banana peels, compared to the main product, which is banana pulp. The objectives of this study were to assess the quality of fermented feed produced from banana stems and to effectively utilize banana stem waste. This research was conducted at Flores Bajawa College of Agriculture. The research started in June-August 2024. The research material was about the utilization of fermented banana stems as additional feed in the ration of finisher phase KUB chickens. Banana stems were chopped as much as 30 kg (75% of fresh material) and rice bran 10 kg (25% of fresh material), water 3 liters, brown sugar 500 g, EM4 3 bottle caps. Fermentation of banana stems produced a protein content of 5. 4% and a crude fiber content of 16. 48%. The quality of fermented feed aroma produced is like alcohol, fragrant, yellowish brown color, no mold growth. The conclusion of making fermantasi animal feed made from banana stems is one of the efforts made to add economic value to farmers, in a situation of animal feed crisis. In addition, the content contained in banana stems is sufficient to meet the needs of KUB chickens

Abstract

The number of springs and river flows is an indicator of the number of raw water sources available. As in Penebel Sub-district, where the available raw water sources can be utilised to meet the needs. The amount of water needed by the people of Penebel Sub-district depends on population growth. In general, the definition of clean water demand is the amount of water needed by the population in an area as a whole to fulfil their needs. The method implemented by researchers in analysing water demand is ‘domestic and non-domestic demand projection analysis’. There are several stages in this analysis, namely the stage of analysing the domestic water needed, the non-domestic water needed, the amount of water lost, the overall clean water demand, the average water demand, the maximum day factor and the peak hour day. The sample data analysed is the data of domestic and non-domestic clean water required from 2025 to 2031. Based on the analysis conducted, it was found that the domestic and non-domestic water demand in 2025 was 46.45 litres/second and 9.29 litres/second respectively and the average amount of water required was 66.89 litres/second. While in 2031 the domestic and non-domestic water demands were 54.01 litres/second and 10.80 litres/second respectively and the average amount of water required was 77.77 litres/second. So it is found that the projected population growth is directly proportional to the projected water demand.
