<![CDATA[The objective of this study was to know the chemical characteristics of surface water in a segment of Sumpil River and the groundwater on its surrounding. The location of this study was in 3 cross sections, consisting of 1 well on the right of the Sumpil River, 1 well on the left of the Sumpil River flow, and 1 point on the Sumpil River flow. The chemical characteristics of the water were determined by the concentrations of cations and anions in the water sample using the Piper Trilinear Diagram with the GW Chart 1.30 computer program. Based on the results of the study, it was shown that the chemical characteristics of the Sumpil River water and the groundwater at the location of this study were the same, where all water samples had an alkaline earth metals content over the alkali content (zone 1), had a strong acidic content exceeding the weak acidic content (zone 4), have a balanced cation and anion pairs, none of which exceed 50% (zone 9), and shown that all of the water in the location of this study were fresh water.]]>

<![CDATA[Many road pavements using asphalt mixtures in Indonesia are found to be not durable, especially heavy traffic roads. Even road damage often occurs early before the service life is reached. Many efforts have been made to improve the strength and durability of the mixture, but have not been effectively. For example, the use of fillers can increase the strength and durability of the mixture significantly, but its performance at low temperatures has an impact on the risk of hardening and cracking. The research objective is to propose the idea of implementing nanotechnology for palm oil waste materials to increase the durability of road pavement materials based on the research roadmap developed. The method used is through five approaches, namely: (i) review of research results on the durability of road pavement materials, (ii) review of research results on the implementation of nanotechnology in road pavement materials, (iii) research gaps, (iv) research ideas, and, (v) proposed research roadmap. A research roadmap for the implementation of nanotechnology to improve the durability of road pavement materials has been prepared. The substance of the research roadmap proposes three ideas, namely maximizing the function of nanomaterials as: (i) anti-aging agent, (ii) protecting water infiltration into the body of the asphalt mixture, and (iii) bonding agent between asphalt-aggregate.]]>

<![CDATA[This paper presents design and implementation of Automatic Switching for controlling the water level in the reservoir of community water supply. The water supply system is energized by 2 sources i.e. power from utility grid and power generated by photovoltaic panels equipped with energy storage. The switching is based on the reservoir water level and determines the operation of submersible pump. The switching system employs electrode sensors in the water control level where 3 conditions are considered to control motor that drives the pump. The Automatic Switching is connected to Automatic Transfer Switch (ATS) that selects power sources to energize the pump, where it may be from the solar PV supported by storage system or from the grid. The selection is based on the remaining energy saved in the storage, when it is sufficient then it is used to energize the pump. Otherwise, the power from the grid is used to supply the pump. The combination of Automatic Switching and ATS determines when the pump is on and which power is taken to supply the pump. The manual system is complemented in the switching system to enable manual operation when the automatic system fails to work for some reason. The whole system is developed in a panel for easy operation and monitoring. The water level indicator is given in the panel for the purpose of adjusting the pump operation based on water level in the reservoir.]]>

<![CDATA[Presence is something that cannot be separated from the learning process, it becomes motivation and discipline information for every activity in it. This study aims to develop a QR Code-based academic attendance application that can be used by Informatics Engineering Education students. The research method used is R&D (Research and Development) using the RAD (Rapid application development) development model. Application development made using Kodular and Moodle. This application contains a QR Code scan menu as the main focus in this media as well as other supporting menus in the form of virtual tours, news, timetables, and UMS stars. In the process of developing this application, several tests were carried out, namely functionality testing using blackbox, usability testing using the SUS (system usability scale) instrument, reliability testing and application compatibility testing using the firebase test lab. used based on the validation carried out by experts as many as three experts from Informatics Engineering Education lecturers and trials given to users as many as thirty-five students from the Informatics Engineering Education study program, it can be said that the application is suitable for use by Informatics Engineering Education students.]]>

<![CDATA[Student admission is one of the processes that exist in educational institutions. Schools accept students by selecting grades, achievements, and other factors. SMK Muhammadiyah 2 Mertoyudan located in Magelang Regency conducts semi-manual PPDB by compiling ledger records and spreadsheets. The school has difficulty getting PPDB historical data and PPDB reporting. Besides the CPDB has difficulty monitoring registration data directly. The PPDB application is developed with the Code Igniter framework with main features that can be accessed by 3 actors (PPDB manager, CPDB and admin). Applications can store historical data, provide convenience with all forms of custom PPDB reporting and can be accessed online by CPDB and CPDB trustees. From the results of the user acceptance test carried out on schools and CPDB, an assessment of 84.8% was obtained which showed that respondents were satisfied with the functionality of the online PPDB application.]]>
