Chemical bonds are one of the basic materials and are important in understanding the mechanisms and chemical reactions and other materials such as stoichiometry and so on. Chemistry bonding material is studied and understood starting from junior high school up to undergraduate students for the science majors at tertiary institutions. The many types of chemical bonds that may occur in the joining of two or more elements make the most of the learning for this material more difficult. In this paper the research designs and builds an application by applying the basics of chemical bonds as learning innovations to facilitate the understanding of studying chemistry. This application is designed using the SDLC (System Development Lite Cycle) system development model or system development life cycle. The SDLC model to be used is the systematic, sequential waterfall method in building software from this research. For the programming language used is Java and uses the MySql Database.

The process of monitoring and evaluating a project needs to be done to ensure the project runs smoothly. The problems that arise at this stage are obstacles to knowing the progress of the ongoing project. Some other obstacles are the potential for file loss, duplication of data, human errors, the need for fast processing, and the need for data integrity of two systems. This study aims to develop a project monitoring and evaluation information system applying deviation calculations. This calculation is carried out to see the realization of the work of an ongoing project. The system design technique uses the use case diagram method which describes the process of the system. The waterfall method is used to develop a monitoring and evaluation information system for this project. The research result is in the form of a project monitoring and evaluation information system that can provide information about the work realization of an ongoing project.Keywords:Monitoring, Evaluation, Deviation Calculation, Information System.

Decision support systems are part of computer-based information systems that are commonly used to support decision making in an organization or company. The decision support system is used as an alternative system that helps in making decisions to recommend the selection of study programs to prospective engineering faculty students. This decision support system uses the Simple Additive Weighting (SAW) method. The SAW method in this study uses five criteria, namely the value of mathematics, the value of English, the value of technology education, the value of cultural arts, and the income of parents. There are four alternatives used, namely Informatics, Civil Engineering, Architecture, and Urban and Regional Planning (PWK).

Seiring berkembangnya teknologi informasi yang begitu pesat,  khususnya dalam perkembangan komputer baik teknologi maupun perangkatnya, hal ini menuntut pengetahuan yang lebih banyak dalam menjalankan komputer/laptop bagi user, bukan hanya dalam mengoperasikannya saja tetapi juga dalam instalasi dan troubleshooting. Sehingga akan mempermudah user apabila menghadapi kendala-kendala kedepannya tanpa harus membawa komputer/laptop mereka ke tempat service. Pada umumnya, solusi apabila konsumen mengalami permasalahan performansi pada software adalah melakukan instalasi komputer pada tempat service komputer. Saat ini Kurikulum 2013 yang diadopsi oleh SMA sederajat, mata pelajaran Teknologi Informasi dan Komputer (TIK) bukanlah mata pelajaran wajib. Yang mana sekolah hanya memberlakukan mata pelajaran TIK sebagai mata pelajaran pilihan. Sehingga membuat siswa/i SMA sederajat tidak memiliki skill dalam perbaikan komputer/laptop mereka masing-masing. Pelatihan ini dirasakan sangat perlu dalam menambah wawasan mereka dalam menghadapi era revolusi digital. Dengan kegiatan pengabdian kepada masyarakat  ini diharapkan siswa/i SMA Negeri 2 Banjarmasin dapat memiliki pengetahuan dalam perbaikan komputer/laptop mereka meliputi instalasi sistem operasi windows, instalasi software pendukung, dan mengatasi gangguan jika terjadi permasalahan sederhana yang timbul sewaktu-waktu. Kata Kunci : Instalasi komputer, Troubleshooting, SMA Negeri 2 Banjarmasin

Accounting information systems play an important role in recording a company's transactions. Because it can assist companies in working on their financial reports, so that the resulting data is well organized and can speed up the data processing process. CV. RR Wasilah Teknik is a company engaged in welding and lathe services. The main problem that occurs in this company is that it is still recording transactions manually and using Microsoft excel. This results in the system not running effectively and efficiently. So, it is necessary to make a computerized application. The research method is applied to the research phase such as data collection, system analysis, system design, system implementation, and system testing. The results of the study are cash management applications that help companies record incoming and outgoing cash transactions. This application helps the system running in the company to be more effective and efficient.
