The competition level between companies on executing product marketing is rapidly increasing, so the companies have to understand the importance of correlation between external environments of company with consumerâ€™s needs. One of the efforts that can be done is by utilizing data warehouse and the application of infrastructure in information and technology field. This research combined Association RulesÂ method to extracting pattern and finding every possibility that potential to increase sales and Holt-Winter Multiplicative method to estimate the alteration of trend on the seasonal data. After passed through data processing process by using RapidMiner tools, information that consists of correlation pattern between rule that describe the comparison of product and the sales working area and season that affects the product sale. The pattern used by company to know which product is often purchased by customer. Besides that, this research produces changing trend data of PT ABCâ€™s product that generated by result of previous data comparison with forecast data. Based on value of error rate Mean Absolute Percentage Error (MAPE) in estimating forecast result on the PT ABCâ€™s sales transaction data during 3 years, it shows good level of accuracy. Result of data test, by considering rule that formed and forecast result so the company can control and manage product in order to avoid incorrect sales. This thing will effect on repression of operational cost and PT ABC can identify available opportunities to increase sale of agricultural medicine.

Big data merupakan istilah yang digunakan untuk gudang data yang sangat besar atau kompleks sehingga aplikasi pemrosesan data tradisional tidak memadai untuk mengatasinya. Tantangannya meliputi analisis, pengambilan, pencarian, berbagi, penyimpanan, transfer, visualisasi, kueri, dan pembaruan serta privasi informasi. Namun, data yang sangat besar ini tidak dapat dengan mudah ditangani karena sebagian besar sistem CS bersifat relasional, dan diperlukan penyesuaian sebelum pemrosesan apa pun. Dengan munculnya Big Data, sistem NoSQL baru datang untuk mengatasi masalah data relasional ini. Jadi, kami mengusulkan pendekatan untuk memigrasi data CS historis dari relasional ke sistem NoSQL, dan menggunakan lingkungan terdistribusi yang berisi banyak node. Sebagai eksperimen, kami memigrasikan data yang dihasilkan oleh CS minyak dan gas ke sistem NoSQL terdistribusi yang sesuai, dan kami melakukan beberapa eksperimen data mining padanya untuk membandingkan hasil dan membuktikan kinerja yang diperoleh.

Mojosongo Subdistrict, Boyolali District with material on implementing marketing strategies by optimizing Facebook social media and endorsements through local influencers which aim to increase sales and increase buyer visits. Influencers can create an increased brand image, are inexpensive in cost and have a level of popularity, ability, reputation, and expertise in endorsing a product or service. The presentation of the material was accompanied by hands-on practice and also given time for discussion and questions and answers between the presenters and participants in community service activities (PkM). This activity was carried out face to face which was enthusiastically attended by the owners and employees of the AJB food stall in Boyolali. Online marketing training activities involve a team of lecturers from the University of Science and Computer Technology (STEKOM) Semarang from various cross-disciplinary fields, such as information systems, graphic design, computerized accounting and informatics engineering. It is hoped that from the results of this training, MSME actors can continue to improve their skills in the field of online marketing.

This research serves the virtual Synchronous Generator finding and oversight building of the Multi-port Autonomous Reconfigurable Solar (MARS) structure to bring backing to the alternating-curring network under various events on the network and presents a “model-based predictive control” (MBPC) oversight finding for the MARS structure to bring backing to the MARS structure alternating-curring network while the density innovation is recognized in the system. The main objective is to nominate a “model-based predictive control” leading oversight design that can bring density backing while unexpected density alteration. In this study, a comprehensive application of a virtual Synchronous Generator-based oversight innovation for the MARS structure is given. The expected oversight finding and control architecture of the MARS structure is evaluated by simulation on the “PSCAD”/EMTDC simulation platform to show performance under various operating conditions and calculated in the “Opal-RT” offline simulation model that also can be adapted to complete the certified “control-hardware -in-the- loops” (c-HIL). The dominant density backing performance is a conceivable combined improvement for each current network-unified capability transistors system. By increasing infiltration of transistors system-based stuff, passivity and immediate density feedback potentially decrease. Leading “model-based predictive control” (MBPC) finding to provide density backing to current topologies of unified “photovoltaic” (PV), battery-based “energy storage system”s” (ESS), and “high-voltage direct current” (HVDC) method named “multi-port autonomous reconfigurable solar” (MARS) is suggested. The expected oversight finding for regularly based on virtual Synchronous Generator-based oversight. Simulation of the MARS-HVDC method by the recommended oversight approach was assumed and authorized for MARS related to a “small short circuit ratio” (SCR) network in a “PSCAD”/EMTDC assumed habitat. The expected oversight finding displays superior work in the phrase of increasing rock bottom frequency and increasing constant-area frequency concerning no density oversight. The results of this research indicate that the MARS architecture by Synchronous Generator -based oversight brings exceptional heat backing by inserting higher active potential to the structure while equitable stage error compared to the Virtual Synchronous Generator - based oversight mode. The Synchronous Generator-based oversight mode is also balanced and brings better work in the phase of density rock bottom and balance-area increase. In the great feedback, the Synchronous Generator-based oversight mode is good than the Virtual Synchronous Generator-based oversight mode for each short circuit ratio set tested. MBPC-based oversight is entrenched in a virtual Synchronous Generator-based oversight algorithm. The recommended oversight innovation and control architecture of the MARS structure was calculated on the MARS structure in the “PSCAD”/EMTDC simulation environment. The simulation results show an increase in nadir frequency and steady-state frequency provided by the Multi-port Autonomous Reconfigurable Solar (MARS) structure via MBPC control. In future research, leading oversight methods are required to bring steady action down to unsteady error.

In the era of the new normal, maintaining health and hygiene has become critically important, especially in preventing the spread of viruses. One effective way to achieve this is through regular handwashing. Schools are particularly susceptible to the transmission of viruses and bacteria, which is why it's crucial to implement an effective hand sanitizer system. However, the use of conventional hand sanitizer bottles that require manual pressing or opening still carries the risk of virus transmission. Therefore, there is a need for the development of an automatic hand sanitizer system to reduce the risk of virus transmission. This research aims to design an Arduino-based automatic hand sanitizer system at SD Kanisius Genuk. The automatic hand sanitizer system utilizes an ultrasonic sensor to detect the distance between an object, in this case, a hand, and the hand sanitizer. When the hand approaches within a certain distance, the hand sanitizer fluid is dispensed automatically through a mini 5V pump. Additionally, the device features a liquid level sensor that provides information about the hand sanitizer fluid level via an LCD screen. The theoretical significance of this research lies in enriching knowledge about programming using the C++ programming language in designing an automatic hand sanitizer system. Furthermore, the research is expected to enhance creativity, innovation, and knowledge development in response to technological advancements. The practical benefits of this research include facilitating students, teachers, and guests at SD Kanisius Genuk in using the automatic hand sanitizer, thus reducing the risk of virus transmission. Additionally, this research can serve as a reference for universities and contribute to the field of human resource management knowledge.
