Heat transfer in diesel engines is known to affect engine efficiency and emissions. Increased heat transfer to the combustion chamber walls reduces the pressure in the cylinder and the average gas temperature, which reduces the work transferred to the piston per cycle. Therefore, the amount of heat transfer in an engine largely depends on the efficiency of the engine. Changes in gas temperature due to heat loss from the combustion chamber also affect the formation of pollutant emissions. Higher temperatures in the cylinder promote NOx emissions, while lower temperatures in the cylinder create Particulate matter in the exhaust. Engine heat transfer is important, so engine heat transfer results must be accurately estimated.

The crankshaft is one of the main components that works in a combustion engine as a converter of the up-and-down motion of the piston into a rotary motion against the shaft used to drive chain wheel components, gears, or other components. In the research conducted, namely the analysis of the use of materials on the crankshaft using Ansys software with the aim of knowing the stress distribution, displacement, and safety factor. conclusion where the value of the radial free force of the crankshaft is 15 N, and the data that takes place on the crankshaft as follows: Based on the results of the analysis using Ansys, the maximum stress of 0.0866 N/mm2 is obtained. The displacement that occurs using Ansys analysis is 1.3461e-03mm. The safety factor that has been analyzed is 1.5 + 10.

Reliable and high-performance Internet access is essential to support practical activities in the IBN Lampung Computer Laboratory. Dependence on a single ISP often leads to connection disruptions, reduced service quality, and interruptions in the learning process. This study aims to design and implement a Mikrotik-based load balancing system to improve Internet performance by utilizing two ISP links and providing an automatic failover mechanism when one link becomes unavailable. The research employs the Network Development Life Cycle (NDLC) approach, which includes network requirement analysis, multi-WAN topology design, implementation of load balancing and failover configurations on Mikrotik, and performance testing. The results show that the load balancing system successfully distributes traffic more evenly, enhances connection stability, and provides more consistent Internet speed. Additionally, the failover mechanism works effectively and ensures service continuity when an ISP experiences downtime. In conclusion, the implementation of a Mikrotik-based load balancing system effectively improves Internet access quality and supports smoother laboratory activities.

In today's modern era, every organization or business needs an information system, and it is used to improve information requirements, quality standards, and productive employee work. Organizations, institutions or businesses that have implemented an automated management system for all their administrative functions have also been encouraged to continue to do so by developing an information management system that integrates with or links to other components. Systems for managing information then help businesses integrate their own information, improve the quality of information they have access to, manage it effectively, and accelerate information processing so that routine tasks can be automated and innovated into business products that improve services and workflows. In this case, it can be said that management information systems and the technological capabilities they support have the potential to bring about significant changes in the economic and management fields.

In the current era, people who own land containing trees and plants have been used as buildings for business and personal interests, increasing population has resulted in increased housing needs, the use of open space for public entertainment has decreased due to the activities of people who are busy working to make ends meet. and the lack of public interest in making the environment more beautiful and sustainable. Even though the existence of a garden in a large building greatly influences the atmosphere in the environment around the building. Apart from that, one of the reasons is the lack of interest of the community in creating a beautiful environment because it is quite difficult to find the services of gardeners around where people live. The problem that occurs is that these gardeners are not exposed to all the gardens they build.

Karangawen State Madrasah Tsanawiyah (MTs) is a junior secondary level formal education institution which is geographically located in Karangawen Village, Karangawen District, Demak Regency, with a total of around 800 students divided into 25 classes. This Madrasah has been officially established since 1997. With a large number of students, MTs Negeri has been supported by facilities and infrastructure capable of supporting the process of teaching and learning activities as well as administrative activities. Currently MTs Negeri Karangawen already has 20 units of computers in one computer laboratory equipped with a computer network to support teaching and learning activities. In the field of administration, it has also been supported by 5 units of computers that are used by administrative staff in order to serve all teaching and learning process activities, including in the service of student financial payments.

Indonesia's development and financing for its country comes from the income of MSMEs in Indonesia. MSMEs are the economic cycle in Indonesia and MSMEs have a very high influence on improving the economy in Indonesia. More entrepreneurs and MSMEs will increase the economic value of a country, namely Indonesia, because the economy will grow in proportion to the growth of MSMEs with MSMEs, people are required to become entrepreneurs and as a producer and is expected to be able to import its products abroad to increase income from abroad and domestically. The survival of MSMEs is very important for the continuity of MSME businesses, for this reason the government provides various kinds of stimuli so that MSMEs are able to survive under certain conditions, especially during the Covid-19 pandemic. MSMEs need to make improvements in terms of financial governance. This understanding starts from an early age, namely in the MSME environment to support government programs that intensify calls for Indonesian people to comply with reporting which plays a very important role in the country's development. The main problem obtained from observations of MSMEs in Api-api village, Wonokerto is that they do not understand financial governance for MSME entities for business sustainability, so it is necessary to hold a workshop regarding strengthening financial governance of MSMEs to improve business sustainability in Api-Api Village, Kec. Wonokerto Regency Pekalongan. Goals and targets of community service in Api-Api Village, Kec. Wonokerto Regency Pekalongan is so that the public understands good financial governance and how to prepare financial reports for community businesses in Api-Api Village, Kec. Wonokerto Regency Pekalongan. The number of participants was 30 MSME business actors. The implementation method is carried out by presenting workshop material directly (offline) in Api-Api Village, Kec. Wonokerto Regency Pekalongan. The output of this community service is in the form of scientific journal publications in the ITS NU Pekalongan Community Service Journal and cinematic videos of the implementation of community service.

DDOS (Distribute Denial of Service) is a type of structured attack. This attack has been around since 1990. DDoS attacks are capable of paralyzing servers by flooding network traffic and causing it to go down. To overcome this problem, the way to detect DDoS attacks has several methods and algorithms, one of which is the Artificial Neural Network algorithm and uses the Machine learning method due to the fast computing process, high accuracy, and this research uses the SKKNI research method Number 299 of 2020. The analysis was carried out uses training data from the latest dataset, namely CICIDS2017, which is a development of a previously existing dataset. DDoS attack detection testing using the confusion matrix method obtained bot precision of 0.99, recall of 0.99, and f1score of 0.99, 3
