In automotive spark plug ignition, gasoline-fueled vehicles require spark ignition system equipment. One of the electronic cdi spark plug ignition systems uses electronic equipment and components that replace conventional spark plug ignition systems. In this study, the design of the electronic cdi spark plug ignition system using the main equipment of the alternator produces an ac output voltage source on the exiter coil winding. The results of the design of the equipment are generated by a timer signal from the pulser component related to the rpm speed of the alternator permanent magnet rotor shaft which is driven by the rotation of the ac electric motor shaft. The ignition timing process of the spark plug is controlled by the charge/discharge condition of the electronic capacitor charge in the cdi device to produce an ac power supply voltage, the output time function to the primary input of the coil is expressed as the Vprimer(t) parameter in volts. The result of the primary voltage Vprimer(t) at the primary input of the induced coil generates a high voltage at the secondary output of the ignition coil, which is expressed as the Vo(coil) parameter. The result of a high voltage Vo(coil) momentarily connected to the spark plug produces spark ignition which indicates that there is a spark in the spark plug gap. 

The lack of access to the internet network in schools is a factor in the slow teaching and learning process, because the lack of wireless signal coverage also causes the school community to only gather at one point. In an effort to deal with this problem, researchers built an inter-vlan network blueprint with wireless hotspots, in order to improve network performance and network security. In the process of building an inter-vlan network blueprint with a mikrotik hotspot, using the ppdioo method, among others, prepare preparation, plan plan, design design, implement, operate, optimize optimization. From the results of this study, in building a blueprint for an inter-vlan network with a mikrotik hotspot, we get the appropriate results from the initial plan. Which can improve network performance and expand access to internet network coverage.

In this paper, we try to solve a simple DSS with Microsoft Excel by using Solver.

Mushrooms, as eukaryotic organisms that dominate the kingdom Fungi, play a crucial role as decomposers of organic matter in ecosystems. The diversity of mushrooms encompasses a variety of species, ranging from microscopic to macroscopic, widely distributed in various environments. Superficial fungal infections, or superficial mycoses, focus on fungal infections limited to the surface of the skin, nails, or hair. Such infections are typically localized, not penetrating deep into tissues and remain primarily a local condition. In the context of this study, the optimal model developed through training successfully achieved a validation accuracy of 92.590% and a training accuracy of 88.933%. Evaluation results indicate a precision value of 94%, a recall value of 93%, and an F1-score value of 92%. These findings highlight the success of the model in classifying and evaluating superficial fungal infections with high precision.

Technological growth is increasing from year to year, this is indicated by the use of computers in all aspects, be it service companies, trade, or industry, ranging from small, large, to multi-national companies. KAMDATU is the procurement of office furniture. The supply chain process at CV. Kamdatu involves several external parties, namely suppliers, customers, shipping, and management. The problems faced by CV. Kamdatu is located in a sales and purchase processing system that is still manual (not yet computerized) so that it is prone to calculation errors, searching for item data, and delays in stock information, in addition to recapitulating reports takes a long time because employees have to recap data first this is because the absence of management in the purchase of goods and production The E-Supply Chain Management system that will be applied to CV Kamdatu focuses on the automation of information between companies, suppliers, consumers and delivery of goods. Inventory and fulfillment of customer orders are more controlled. Based on these problems the researcher uses a methodological method, namely the Unified Approach (UA) UA, which is an object-oriented development methodology that combines existing processes and methodologies with uses the Unified Modeling Language (UML) as the modeling standard. The result of this research is to produce an application that has features that support the processing of buying and selling transactions
 
 

With current technological developments, mobile phones can provide Bus Rapid Transit (BRT) transportation payment systems that still use ineffective tickets where passengers have to queue to buy ticket tickets. As well as the physical condition of the ticket which is easily wet and torn. In fact, currently there are many payment systems that use technology assistance as a payment method that can minimize queues for purchasing transportation tickets. Such as smart cards used by Trans Jakarta transportation and the use of smartphones as a means of payment for Go-Jek and Grab transportation. So we need an innovation that can replace the BRT payment system which still uses tickets using the current technology. For this reason, a mobile-based Bus Rapid Transit (BRT) payment system was created so that passengers can easily make transportation payments. This system can validate voucher codes and make payments.
