Zakat, Infaq and Sadaqoh are forms of worship for Muslims to carry out the third pillar of Islam. The amil zakat, infaq and shodaqoh nahdlatul ulama (lazisnu) institutions in the village of Sepanyul Gudo in their management are still experiencing many problems because there are still many obstacles, especially the management of ZIS funds that enter and their distribution is often problematic because the incoming and outgoing data are not integrated. In addition, it can also disseminate information on the distribution of ZIS funds carried out during religious activities that are inefficient and disrupt these activities. With the description of the problems that occur, design a system that can help solve this by designing a web-based data management information system for zakat, infaq and shodaqoh recipients. The application is designed using the PHP and MySQL programming languages as databases. System development using a Linear Sequential Model approach is accompanied by a design using UML (Unified Modeling Language) including use case diagrams, activity diagrams, and sequence diagrams. So as to produce a web-based online information system, so that people who will participate in ZIS can easily access it.

Currently to get a strong firewall is still constrained by expensive costs. Only large companies or agencies can obtain these devices, while small and medium-sized companies are still unable to obtain reliable firewall devices. Therefore, it is necessary to need inexpensive security devices or firewalls for medium and small companies and agencies to protect computer networks from outside interference. Mikrotik RB 750 is a router that can be used to make a network security system that is reliable, inexpensive and easy to configure. In this study, the author tries to provide a network security system solution using Packet Filter Firewall with the router in bridge mode and compares network security systems in other research journals. From the results of the comparison, several series of network security protections are produced, namely changing the proxy to bridge mode, IP address protection, content protection with mangle, Mikrotik device protection, traceroute protection, port scanner protection, Bogon IP protection, and Bruteforce FTP protection. After conducting a series of tests from the results of the network protection setup using the Mikrotik RB 750 in bridge mode, the authors conclude that not all packets that pass through the bridge firewall device can be filtered. One of them is ICMP flooding packets. Mikrotik devices with Firewall bridge mode cannot calculate the number of ICMP packets that pass, so the author blocks ICMP packets with the 8:0 option (echo request) that goes to the local network.

Scholarships are grants in the form of financial assistance given to individuals that aim to be used for the continuation of the education achieved. With this scholarship program, it is hoped that it can help students who have problems in financing. The selection of scholarship recipients at SMK YPM 14 Sumobito still experiences problems in decision making, because the assessment process is not always decided based on definite considerations but the policy of the decision makers who ultimately determine the scholarship recipients. This is because there is no method that can predict prospective scholarship recipients. Eligibility of prospective scholarship recipients is determined by applying the Naïve Bayes method. This method was chosen because it was able to study the previous case data used as test data. After testing with the Naïve Bayes algorithm using the Rapidmaner tool, the results were 90.48% accuracy, 96.88% precision, 83.33% recall each. So that it can be said as a good key to apply for prospective scholarship recipients. Keywords: (scholarship assistance, Data Mining, Naïve Bayes).

Indonesia is a country with significant potential for developing solar energy. However, one of the challenges in the electricity sector is the reliance on fossil fuels as the primary energy source. To mitigate the impact of this dependence on fossil fuels, it is crucial to explore new sources of renewable electricity. Solar cells, which convert sunlight or ultraviolet (UV) rays into electrical current, offer a promising solution. Sunlight is a sustainable and abundant energy source, making it a viable option for future energy production. Due to the nature of solar cells, which depend on sunlight, the output they produce is variable and influenced by changing weather conditions. Therefore, energy storage solutions, such as lithium-ion batteries, are needed to store the electricity generated by solar cells. This study will examine the characteristics and efficiency of solar cell input on the capacity of lithium-ion battery storage systems, focusing on the relationship between sunlight intensity and the generated current and voltage. An off-grid photovoltaic (PV) system relies solely on solar energy, utilizing a series of photovoltaic modules. Consequently, sunlight intensity significantly impacts the solar cell's performance by affecting the voltage and current produced, which in turn influences the system's performance. This research aims to assess the efficiency, advantages, and disadvantages of comparing the output results between series and parallel configurations of solar cells to meet desired needs. Testing and data collection will be conducted using simulations with PV Syst and Meteonorm software.
