Space phenomena are natural events that are rarely seen by humans and are still a lot of mysterious and interesting things to observe and study. In Indonesia, there are still few places to observe and study space phenomena. The Sumatran Institute of Technology (ITERA) has a technical implementing unit as well as a study program related to space. The units are the Lampung ITERA Astronomical Observatory Unit (UPT OAIL) and the Atmospheric and Planetary Science Study Program. However, these units and study programs do not yet have an information system that can store various space data and display them, especially for the public to see. This is the background for us to do community service for lecturers and students in the form of making the OAIL database system. The information system can be used to store space data to be studied and can be seen by the public. The form of the system is website-based so that people throughout Indonesia, especially on the island of Sumatra, can see various space phenomena. For three months, the information system was successfully created and can be implemented by UPT OAIL, so that this community service activity went according to plan and well. It is hoped that the information system can always be developed and useful for the benefit of learning at ITERA and the community. Keywords: space, database, OAIL, astronomical observatory, information system.

APPLICATION OF HYBRID ENERGY TECHNOLOGY: MİCRO-HYDRO TURBİNE AND SOLAR PANELS TO INCREASE ELECTRİCAL ENERGY PRODUCTİON İN DUSUN BATU SAENG, TANGGAMUS, LAMPUNG. Dusun Batu Saeng, Tanggamus, Lampung is one of the areas that utilize the potential of the surrounding natural resources. One of the potentials used is river water which is used as a Micro Hydro Power Plant (PLTMH). However, the source of electrical energy that has been used for 10 years does not appear to be optimal in its utilization. This is because many components are damaged and unfit for use which has reduced their performance. The production of electrical energy from PLTMH is 8 kW which is distributed to 20 houses, this amount will be reduced during the dry season to 6-7 kW. Based on that, it is necessary to replace components such as turbines and generators with a capacity of 10 kW. In addition, during a prolonged dry season, it can also be utilized by installing a 1 kW photovoltaic as a Solar Power Plant (PLTS). Thus, by utilizing water and solar sources, more optimal electricity production can be produced through hybrid energy from PLTMH and PLTS in Dusun Batu Saeng, Lampung. The implementation stages include literature study, site survey, group discussion forum, design and planning, design and preparation, manufacture of PLTMH and PLTS, installation of PLTMH and PLTS, monitoring and evaluation, and final report. The result of this program is an increase in electricity production from 8 kW to 11 kW of hybrid energy from PLTMH and PLTS. It is hoped that in the future this program can be applied to other areas so that they become energy-independent communities.

The interface of the automatic answer assessment system is plagued by several issues, including an unfamiliar layout, unresponsive design, inconsistency in elements, and a lack of clarity in presenting information. These problems significantly hinder the overall user experience. As a result, this study aimed to address these challenges by designing a user-centered experience for the automatic answer assessment system, using a high-fidelity prototype tailored to meet user needs. The user-centered design method involved four crucial stages: Specify The Context Of Use, Specify Requirements, Create Designs, and Evaluate Designs. Through rigorous usability testing with teachers, the design achieved an impressive effectiveness rating of 90%, firmly establishing it as a "very effective" solution. Additionally, it demonstrated high efficiency with a value of 0.01307 goals/sec, and teachers expressed positive feedback, confirming the satisfaction and usability of the new interface. Similarly, students' usability testing yielded noteworthy results, with a 90% effectiveness rating, also classified as "very effective." The interface showcased a high level of efficiency, with a value of 0.0849 goals/sec. While the satisfaction value fell below the PSSUQ norm, students still found the interface to be user-friendly and satisfactory. Furthermore, the user experience testing, utilizing the UEQ-S, provided valuable insights. For teachers, the pragmatic aspect scored 1.85, the hedonic aspect scored 2.33, and the overall aspect received a commendable score of 2.09, all of which fell within the excellent category on benchmarks. Similarly, students' ratings were highly positive, with scores of 2.14 for both pragmatic and hedonic aspects, and an overall score of 2.14, signifying an excellent user experience.The retrospective think-aloud validation test reaffirmed the positive response from prospective users.

Purpose: In the learning process, most of the tests to assess learning achievement have been carried out by providing questions in the form of short answers or essay questions. The variety of answers given by students makes a teacher have to focus on reading them. This scoring process is difficult to guarantee quality if done manually. In addition, each class is taught by a different teacher, which can lead to unequal grades obtained by students due to the influence of differences in teacher experience. Therefore the purpose of this study is to develop an assessment of the answers. Automated short answer scoring is designed to automatically grade and evaluate students' answers based on a series of trained answer documents.Methods: This is ‘how’ you did it. Let readers know exactly what you did to reach your results. For example, did you undertake interviews? Did you carry out an experiment in the lab? What tools, methods, protocols or datasets did you use The method used is TF-IDF-DF and Similarity and scoring computation. Theword weight used is the term Frequency-Inverse Documents Frequency -Document Frequency (TF-IDF-DF) method. The data used is 5 questions with each question answered by 30 students, while the students' answers are assessed by teachers/experts to determine the real score. The study was evaluated by Mean Absolute Error (MAE).Result: The evaluation results obtained Mean Absolute Error (MAE) with a resulting value of 0.123.Value: The word weighting method used is the Term Frequency Inverse Document Frequency DocumentFrequency (TF-IDF-DF) which is an improvement over the Term Frequency Inverse Document Frequency (TF-IDF) method. This method is a method of weighting words that will be applied before calculating the similarity of sentences between teachers and students.
