Nowadays, 4G LTE (Long Term Evolution) telecommunication technology that has spread throughout Indonesia is growing rapidly. However, the coverage of 4G LTE has not been implemented well in Indonesia, one of them is in Sragen. So to be able to increase the quality of 4G LTE network, it is necessary to optimize the coverage area of 4G LTE network in Sragen by using the physical tuning method, which is to adjust the antenna tilt, azimuth antenna, power. Key Performance Indicator is a reference to determine the performance of a network. The measured parameters are reference signal reception power (RSRP), reference signal reception quality (RSRQ), signal interference noise ratio (SINR). The results from the optimization are the percentage of RSRP was initial 45.87% to 75.58%, an increase of 29.72%. While the RSRQ value increased by 20.78%, with an initial value was 27.84% to 48.62%. SINR increased by 5.29% with an initial percentage was 4.87% to 10.16%.

The development of Outcome Based Education (OBE) Information System is done as a solution to academic problems related to the achievement of graduate learning for students. In addition, the OBE system is a form of effort to improve academic quality in order to be able to monitor and measure the development of student learning outcomes in a college study program. The Outcome Based Education system includes all grades processing based on Course Learning Outcomes which is related to Graduates Learning Outcomes so that the outcomes of each student can be measured. This information system is developed by the Rapid Application Development method, and uses the Yii2 Framework with the concept of MVC (Model, View, Controller) where system programming is separated based on application components, such as: manipulating data, controllers, and user interfaces. The use of the RAD method and the Yii2 Framework in making applications can be done quickly and in a structured manner making it easier for future developments. The developed system has been successfully tested and applied in the Electrical Engineering Study Program, Civil Engineering Study Program and Mechanical Engineering Study Program, and planned to be implemented in all study programs of the Faculty of Engineering, Sebelas Maret University. This information system can be applied not only in the engineering faculty of Sebelas Maret University but also outside the university which requires an information system to measure the learning outcomes of graduates.

Indonesia adalah negara agraris, tetapi disayang saat ini semakin sedikit generasi muda yang mau terjun di bidang pertanian. Berdasarkan data dari Kementerian Pertanian petani muda di Indonesia yang berusia 20-39 tahun hanya sekitar 2,7 juta orang yang artinya hanya sekitar 8 persen dari total 33,4 juta orang petani. Untuk mewujudkan cita-cita Indonesia Lumbung Pangan Dunia tahun 2045 sangat pentingnya mengajak generasi muda atau kaum milenial untuk terjun dan menekuni usaha pertanian. Hal tersebut secara mikro juga tampak di dalam minat para pemuda untuk terjun ke bidang pertanian di Dusun Ngentak, Bulakrejo, Kabupaten Sukoharjo. Para pemuda perlu didekati dengan fakta bahwa pertanian tidak identik dengan terbelakang, tetapi dapat pula menarik dan modern dengan mengimplementasikan teknologi kekinian. Sehingga di dalam program pengabdian ini akan dilakukan implementasi dan sosialisasi smart farming hidroponik berbasis Internet of Thing (IoT) di. Perlu dilakukan sosialisasi dan edukasi teknologi pertanian cerdas atau smart farming agar bisa peningkatan efisiensi produksi, kualitas dan kontinuitas produk-produk pertanian terutama hortikuktura. Selain itu penerapan smart farming juga akan menarik generasi milenial untuk tidak malu menggeluti bidang pertanian. Berbagai macam sistem hidroponik akan dikenalkan baik itu sistem sumbu (WICK) deep flow technique (DFT), Nutrient Film Technique (NFT), sistem rakit apung (Floating Hydroponics System FHS), dan lainnya. Masyarakat juga perlu diedukasi untuk mengetahui parameter-parameter penting yang mempengaruhi pertumbuhan tanaman hidroponik seperti nilai pH, nilai EC (electrical conductivity), suhu nutrisi, dan kadar oksigen. Pengabdian ini diharapkan dapat meningkatkan antusias masyarakat terutama generasi milenial untuk menerapkan smart farming hidroponik.

This review of the literature looks into the use of vibration and thermal signals for the diagnosis and detection of bearing problems in brushless DC (BLDC) motors. The study highlights the efficacy of current developments in diagnostic algorithms and signal processing approaches in detecting bearing irregularities. The comparative study of vibration and heat monitoring techniques is highlighted, along with a discussion of each method's benefits and drawbacks. The integration of various methods for improved fault detection accuracy is also examined in the paper. The results indicate that a hybrid strategy that combines temperature analysis and vibration provides a reliable way to identify BLDC motor problems early on, which could enhance maintenance plans and operational dependability.

Technology in sector communication is growth rapidly, which is marked by the increasing number of facilities offered, for example the growth of data, voice and video communication. The technology that can answer these communication demands is Long Term Evolution Adavanced (LTE-A) technology. To optimize the quality by using a combination of frequencies on LTE-A. This research comparing results of non-Carrier Aggregation (Non-CA) and Carrier Aggregation (CA). The frequency band that use existing frequency one of cellular operator in Surakarta 1800 MHz and the additional frequency for CA 2100 MHz. The result shows signal level value is above th threshold -80 dB increase from 89.51 to 96.04%. The percentage of reviewed RSRP if the value is above threshold -105 dBm increased from 83% to 95.44%. the parameter of distribution SINR in percentage values are above threshold above 5dB increased from 47.22% to 69.67%. The value of the mean throughput increase from 25.41 Mbps be 37.31 Mbps, with target KPI 12 Mbps. The number of rejected user in the network decreased from 2.2% to 0.6%. Parameters that are reviewed in this research can meet the target KPI.
