Abstract

Perhatian khusus dan serius dari semua pihak dalam penanganan sampah masih sangat dibutuhkan. Penanganan sampah bisa dimulai dari kegiatan pemilahan sampah di tingkat rumah tangga. Kegiatan ini bertujuan untuk memberikan pelatihan kepada masyarakat tentang pemilahan sampah. Kegiatan ini menggunakan beberapa kombinasi metode diantaranya metode ceramah, praktik, diskusi dan tanya jawab. Dalam menyampaikan materi, tim pelaksana menggunakan alat presentasi berupa power point, alat praktik berupa tempat sampah dan berbagai macam contoh jenis sampah serta kuesioner pre-test dan post-test. Uji statistik Wilcoxon Signed Ranks Test menunjukkan bahwa terdapat perbedaan bermakna tingkat pemahaman peserta mengenai pemilahan sampah sebelum dan sesudah diberikan pelatihan (p value 0,002 kurang dari 0,05). Maka dari itu, kegiatan serupa dapat terus dilakukan.

Abstract

ABSTRAKKomunikasi cahaya tampak (Visible Light Communication) merupakan solusi untuk komunikasi berkecepatan tinggi pada sistem berbasis Internet of Things. Model pintu otomatis berbasis IoT menggunakan komunikasi cahaya tampak berhasil dibuat untuk keamanan rumah. Komunikasi tersebut dengan panjang gelombang 650 nm berwarna merah diujicobakan untuk jarak 20 cm. Penerima fotodioda mengaktifkan motor servo untuk membuka pintu dengan maksimal sudut rotasi 120 derajat. Ada enam macam kondisi pintu terbuka yang ditampilkan di LCD dan dikirimkan melalui internet ke website. Secara keseluruhan sistem berjalan dengan baik. Komunikasi cahaya tampak juga diujicobakan sebagai sinyal pembawa dengan mendeteksi tegangan yang dikirimkan oleh laser di fotodioda. Berdasarkan ujicoba didapatkan data yang dikirimkan dapat diterima dengan baik, walaupun perubahan tegangan turun sampai dengan 1.5% di fotodioda.Kata kunci: komunikasi cahaya tampak (Visible Light Communication), Internet of Things, pintu otomatis, keamanan, sinyal pembawa ABSTRACTVisible Light Communication (VLC) is a solution for high-speed communication that can be utilized for Internet of Things (IoT) systems. An automatic door model based on IoT using VLC has been successfully assembled for user security at home. This communication, with a wavelength of 650 nm in red light, was tested for 20 cm. The photodiode receiver activates the servo motor to open the door with a maximum rotation angle of 120 degrees. The open door process consists of 6 different conditions displayed on the LCD and transmitted via the internet to the website. In a comprehensive evaluation, the system operates optimally. In addition, VLC was also tested as a carrier signal to examine the voltage sent by the laser. Based on the experiment, the data sent can still be received well, even though there is a voltage change up to 1.5% at the photodiode receiver.Keywords: Visible Light Communications (VLC), Internet of Things, automatic door, security, carrier signal

Abstract

This outreach activity for students was held by SMP Plus Sukaraja Garut, and aimed at increasing students' awareness about the importance of Clean and Healthy Living Behavior (PHBS), especially regarding adequate water intake and regular exercise. The method used in this outreach is through the distribution of brochures and direct presentations at one of the schools in the Garut Regency. Counseling is carried out by providing a pretest and posttest to measure students' level of understanding. The results of this activity show that using brochures as an information medium is quite effective because they can be read repeatedly and the direct presentation here allows for two-way interaction to clarify understanding. This counseling succeeded in increasing students' knowledge and awareness about the importance of PHBS, water intake, and exercise by 78.85%. It is hoped that this PKM activity can encourage students to implement healthy living habits sustainably.

Abstract

Abstract Researchers believe that Positive Emotions can significantly influence the Impulse Buying variable because the more emotional a person is, the more emotional they are because they have no financial problems, get good religious and social studies, and have a happy family who no longer think about prices when shopping. Apart from that, researchers also have a second belief, namely that the Store Atmosphere variable is able to moderate these two variables. This research is quantitative research with an exploratory approach. The data collected in this research used a questionnaire method for 300 people who had incomes above 20 million. This data is called primary data. The data used and collected were analyzed with Smart PLS 4.0. The research results showed that the Positive Emotions variable had a positive relationship and a significant influence on Impulsive Buying and the Store Atmpaoshere variable could moderate the relationship between these two variables.

Abstract

Hydroponic is one of the solutions of gardening methods using water as a nutrition medium. Usually, maintaining hydroponic plant quality and water nutrients are done manually and require human efforts, such as the degree of acidity or wetness (pH), TDS (Total Dissolved Solids), and nutrient temperature. With the Internet of Things technology, we can automate hydroponic control by measuring the nutrients' TDS, pH, and temperature values and controlling water nutrition by pump nutrition needs for hydroponic plants. This research uses the NFT (Nutrient Film Technique) for the hydroponic system and uses lettuce as the nutrition parameter. The lettuce parameters are pH, TDS, and Water Temperature equal to the sensor we used in the proposed IoT system. The condition has 27 classifications, and we use this classification as a reference in decision-making, using the K-Nearest Neighbor (KNN) algorithm to activate the actuator. We improve the simultaneous actuator from previous research with specified intervals and duration to achieve ideal nutritional conditions. The other improvement is that we collect more data and more testing times. The accuracy was 91.2%, with k = 3. From the evaluation results, the accuracy of KNN is quite high and has an advantage, which has better accuracy than the other algorithms and can activate actuator simultaneously. We conclude that the hydroponic nutrient automation system using the Internet of Things method is ready for real planting use with this improvement.
