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.

Partisipasi Politik Pemilih Pemula mempunyai peran penting dalam proses pemilihan umum. Tahun depan Indonesia akan melaksanakan Pemilu untuk memilih DPR, DPRD, Presiden dan wakil, Presiden serta DPD. Dalam Pemilu kali ini jenis pemilih yang menjadi perhatian penting guna melihat tingkat partisipasi politik pemilih khususnya pemilih pemula, pemilu 2024 jumlah pemilih muda  dipredeksi mencapai 52%. Minimnya kesadaran dalam pemahaman demokrasi dan rendahnya pendidikan politik bagi para pemilih pemula tentu dapat menurunkan tingkat partisipasi pemilih pada pemilu 2024 mendatang. Mengingat pentingnya partisipasi politik pemilih pemula dalam pemilu yang akan datang, maka perlu dilakukan sosialisasi pengetahuan dan studi tentang partisipasi politik pemilih pemula pada masyarakat di Kecamatan Ngemplak yang memiliki DPT terbanyak di Kabupaten Boyolali yakni 68.527. Kemudian peneliti mengambil sample Desa Manggung, Kecamatan Ngemplak, Kabupaten Boyolali. Tujuan pengabdian masyarakat ini adalah untuk meningkatkan kesadaran pemilih pemula tentang pentingnya partisipasi politik pemilih pemula. Dalam pengabdian ini metode yang dipakai adalah penyampaian materi dari narasumber dengan nsarana LCD dan dilanjutkan diskusi dan tanya jawab. Hasil dari pengabdian ini adalah meningkatnya kesadaran para kaum muda khususnya pemilih pemula, lebih khusus lagi pemilih pemula dari ibu-ibu  Tim Penggerak PKK, hal ini terlihat antusiasme para peserta dalam interaksi diskusi dan tanya jawab.

The research method used in this study is the research and development method or also called Research and Development. The research design that will be developed in this study uses the development model presented by Borgan Gall. The product produced in this study is an Arduino Nano-Based Distance Measuring Tool with a Display on the LCD on the Flat Side Room Building Material for Class VIII at SMP Negeri 5 Sepauk. The test subjects of this study included two subjects. The first subject is the validator and the second is class VIII students of SMP Negeri 5 Sepauk. The analysis technique used is to determine the effectiveness, practicality, and validity. The percentage of effectiveness from the average of the two analyzes obtained a percentage value of 94.06% with Very Effective criteria used in learning mathematics. The results of the combined teacher and student response questionnaires - the average percentage obtained was 89.55% with very practical criteria. The combined results of the average percentage obtained from the percentage of experts and the results of the measurement trials obtained a percentage of 76,36% with very valid criteria.
