Security is a state in which people or things feel safe from ominous or unsettling hazards, which will then cause them to feel at ease and comfortable. There are many ways to achieve security, one of which is via utilizing and deploying technology. The use of security technology has advanced quickly in recent years, from low-tech to high-tech techniques. By using Arduino as a circuit controller to process input from a vibrating sensor and 4x4 keypad, output to a solenoid as a charity box lock, and a buzzer that serves as an alarm in case of theft, technological or automated methods can reduce charity box theft and also increase the security of charity box locks. The charity box security system tool is made to prevent the theft of charity boxes, which frequently happens in mosques. If someone tries to steal the charity box, an alarm will go off, and you need a pin that has been programmed on an Arduino Ide and stored in EEPROM to open the charity box cover, so this tool can stop charity box theft in mosques.

This study discusses the infusion detection device in a hospital room. This tool is designed to help hospital nurses to cope more quickly to avoid problems due to the infusion. Load cell sensors are used as heavy detectors that send notifications to the nurses through the telegram application that has been installed. The nurse will get a notification message sent to the telegram if the sensor has read the weight. The tool is made using a load cell sensor and NodeMCU Wi-FiESP866 which functions to send notification of the results of sensor data input to the Internet of Things (IOT) platform namely Telegram. Nurses need to be connected to the internet network to get notifications on the telegram. Test results show that the time needed to send and receive notifications on Telegram takes about 2-5 seconds. The message will be sent 3 times, first the infusion WARNING is almost exhausted (alert), second the infusion WARNING is almost exhausted (standby) and the infusion WARNING is almost exhausted (please replace). If the infusion is not replaced by the nurse, it will be warned by Buzzer. However, time can be influenced by the available internet network connectivity. However, time can be affected by the available internet network.

Automatic cocoa fermentation design is expected to facilitate the work of cocoa farmers during the process of reversing and stirring cocoa fermentation based on the right temperature. Fermentation process is of course done in a box or sack so that chocolate quickly produces heat and is cemented. However, in certain conditions, especially when in sacks there are often obstacles in the stirring process. Often the fermented chocolate experiences weathering or moldyness due to the uneven reversal that causes chocolate to clot, causing weathering or moldiness and produce an unpleasant odor and unattractive color on the cocoa beans. To overcome this problem a tool that automatically can turn or stir the cocoa beans evenly. This device is controlled by Arduino Uno R3 with a sensor that is an LM35 temperature sensor and has an LCD output and DC motor. This tool uses Relay to adjust the delay when driving a DC motor. The working principle of this tool, when the LM35 temperature sensor receives heat conditions on the cocoa beans, the LCD will display the condition of the temperature while the relay will instruct the DC motor to move the Cocoa Fermentation rail rotating left or right. The purpose of making this tool is to create a tool that can help alleviate the work of cocoa farmers in cocoa bean stirring activities at the time of cocoa bean fermentation controlled by Arduino.

The large number of family activities carried out outside the home makes them always feel worried and anxious about the activities carried out by the elderly at home. This will be a problem when the elderly carer has important activities outside the home and has to leave the elderly person alone. If an elderly person falls, the sensor will detect the pressure of the fall and reduced balance in the elderly wheelchair. Then the MPU6050 sensor will send input to the nodemcu which controls the entire circuit for processing by sending a signal to the Blynk application as an output processor with a notification in the form of a short message that the elderly person has fallen, from the wheelchair which is displayed on the user's cellphone which has the blynk application installed. With this tool, it is easier for elderly caretakers to know the condition of elderly people when they are in a wheelchair, and it is also quicker to help elderly people if they fall from a wheelchair by notifying them via message notifications in the Blynk application.

Kegiatan pengabdian kepada masyarakat ini dilaksanakan berdasarkan hasil pengamatan terhadap para guru smk di kabupaten aceh selatan yang dianggap masih belum mengenal dan menguasai penggunaan aplikasi WOKWI dalam Pembelajaran Mikrokontroler. Untuk itu perlu adanya pelatihan tentang mikrokontroler menggunakan aplikasi online WOKWI bagi guru SMK dalam pembelajaran Perangkat keras dan Teknologi Internet Of things dan efisien. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan keterampilan serta pembiasaan guru dalam penggunaan Aplikasi WOKWI. Dalam pelaksanaannya, kegiatan pengabdian ini dilakukan dalam bentuk ceramah materi pelatihan secara daring dan evaluasi. Metode survey digunakan untuk mengevaluasi hasil kegiatan melalui pendistribusian angket secara online. Data menunjukkan rata-rata respon baik yang diberikan oleh peserta kegiatan adalah sebesar 92.6%. Dengan kata lain, pelaksanaan pengabdian masyarakatini telah memberikan kontribusi positif terhadap profesionalitas guru dalam pemanfaatan teknologi Informasi

Penulisan karya tulis dan karya ilmiah di bidang pendidikan merupakan salah satu bentuk pengembangan profesi dari seorang guru yang dapat berkontribusi pada peningkatan mutu pendidikan dalam proses belajar mengajar. Namun jumlah karya ilmiah yang dihasilkan oleh keprofesian guru masih berada di angka yang rendah. Salah satu kesulitan penulisan karya ilmiah yang dialami oleh para guru adalah pengembangan ide atau pemikiran menjadi sebuah tulisan karya ilmiah yang koheren dan padu. Untuk itu, perlu dilakukan pelatihan penulisan artikel ilmiah dalam bentuk laporan penelitian maupun penulisan artikel dalam jurnal ilmiah. Hal ini diharapkan dapat meningkatkan dan menambah kemampuan seorang guru untuk bisa dalam keterampilan bahasa verbal menjadi terampil juga dalam menuangkan ide dan pemikirannya dalam bentuk tulisan. Sejumlah guru terutama guru muda yang mengajar di SMA dan SMK di Kabupaten Aceh Selatan menjadi target utama dalam pelatihan ini. Pelatihan ini diharapkan dapat memberikan pemahaman mengenai metode penulisan artikel ilmiah yang baik dan berkualitas, meningkatkan motivasi guru dalam menulis artikel ilmiah, serta menghasilkan naskah/artikel oleh guru yang layak dipublikasikan. Dalam hal ini turut difasilitasi dengan template dari jurnal dan jurnal yang bisa menampung artikel para guru yang layak untuk dipublikasikan.
