Abstract

Kitchen spices are substances that generally come from flavorful plants that are added to dishes for the purpose of flavoring food. Seasonings serve to give food a better taste. With so many types of spices, storage in the warehouse is needed a place that fits the types of spices. So that the supply is not confused to store kitchen spices and if needed is not confused anymore. The supplier will send spices according to consumer demand. In this way, if the spices are used up, Delphi will automatically instruct the speakers and cameras to monitor the supply to enter the spices. What has been determined by consumer demand is how many spices are needed and a data base to collect data. RFID as taking customer data by using an ID card to enter the kitchen spice storage warehouse. Loadcell as measuring the weight of the weigher.

Abstract

This study aims to design a VPN network system by utilizing a public network, where this system aims to provide security by using IPSec in providing confidential information through the L2TP tunnel method from the server to the branch/client computer and vice versa. VPN is implemented using layer 2 tunneling protocol (L2TP) using two Mikrotik routers. There are only a few changes in the computer network configuration to minimize costs and implementation time. Tests are carried out to implement security on the network using the command prompt, where the admin observes packet loss and delay parameters to find out the increase in security quality on the network

Abstract

Aglonema is a plant that is widely cultivated by ornamental plant lovers, because it has various species with varied and beautiful leaf patterns. Aglonema cultivation can be a business opportunity in agriculture because aglonema plants are in great demand but also because the prices offered vary from hundreds of thousands to millions of rupiah. Aglonema plant care is quite easy and simple. However, the wrong aglonema plant care such as irregular watering, excessive fertilizer application, and the wrong plant placement can make plants grow less optimally or even die. Greenhouse is a building that was formed to avoid and treat plants against various kinds of weather. Weather is the state of the atmosphere in a place at a certain time related to air temperature, sunlight, wind, rain and other air conditions. Thus, the types of plants that are not in accordance with the local climate, such as ornamental plants, vegetables and fruit, which have high economic value but are difficult to cultivate in outdoor areas, can be cultivated through climate control in the greenhouse. Various benefits such as controlling air temperature, adjusting humidity levels, to the interval between watering times can be adjusted easily. Internet of things (IoT) is a concept or program where an object has the ability to transmit or transmit data over a network without using the help of computer and human devices. With this IoT, spraying insecticides at the Greehouse for aglonema plants can be done automatically

Abstract

Abstract: Facial recognition is widely used in areas such as video surveillance and database management. Facial images have been used as a preferred biometric feature in many identity recognition systems to obtain good image results in image segmentation. A good image must pay attention to several factors, namely high resolution, good contrast, image sharpness, consistent colors, lack of noise and appropriate lighting conditions. In this face recognition research, using canny edge detection method for 10 original images paired with 10 other images. The original faces taken are male and female. Canny edge detection has a low error rate in image segmentation compared to other edge detections. The purpose of this study is to determine the edge of the image in I-rat and can display the results of a good segmentation of facial images. The results of the test data with data stored in the database in the study is 1 face image produces 67.69% accuracy and 26.92% and 8 other face images produce 100% accuracy. The average success rate of 10 experiments using image segmentation is 89.461%. In conclusion, the canny edge detection method can provide accurate results in the face recognition process.            Keywords: accuracy; canny edge detection; face recognition; image; segmentation  Abstrak : Pengenalan wajah banyak digunakan dalam diberbagai bidang seperti pengawasan video dan manajemen basis data. Gambar wajah telah digunakan sebagai ciri biometrik yang disukai di banyak sistem pengenalan identitas untuk mendapatkan hasil citra yang bagus dalam segmentasi citra. Citra yang baik harus memperhatikan beberapa faktor yaitu resolusi tinggi, kontras yang baik, ketajaman citra, warna yang konsisten, kurangnya noise dan kondisi pencahayaan yang sesuai. Pada penelitian pengenalan wajah ini, menggunakan metode deteksi tepi canny untuk 10 citra asli yang dipasangkan dengan 10 citra lainnya. Wajah asli yang diambil berjenis kelamin laki-laki dan perempuan. Deteksi tepi canny memiliki tingkat kesalahan rendah dalam segmentasi citra dibandingkan dengan deteksi tepi lainnya. Tujuan dari penelitian ini adalah menentukan tepi gambar secara akurat dan dapat menampilkan hasil segmentasi citra wajah yang baik. Hasil dari data uji dengan data yang tersimpan di database dalam penelitian adalah 1 citra wajah menghasilkan akurasi 67,69% dan 26,92% dan 8 citra wajah lainnya menghasilkan akurasi 100%. Rata-rata tingkat keberhasilan dari 10 kali percobaan dengan menggunakan segmentasi citra adalah 89,461%. Kesimpulan, metode deteksi tepi canny dapat memberikan hasil yang akurat dalam proses pengenalan wajah. Kata Kunci : akurasi; deteksi tepi canny; citra; pengenalan wajah; segmentasi

Abstract

Perkembangan teknologi telah mendorong inovasi dalam media pembelajaran, khususnya pada mata pelajaran fisika yang sering dianggap abstrak oleh siswa SMA karena kurangnya pembelajaran praktek atau alat peraga agar lebih efektif. Pemahaman mengenai pengaruh resistor dan kapasitor dalam rangkaian seri dan paralel seringkali sulit dipahami jika hanya mengandalkan teori pada buku teks. Penelitian ini bertujuan untuk merancang dan membangun alat peraga interaktif berbasis mikrokontroler Arduino Mega 2560 sebagai media pembelajaran. Alat ini dilengkapi dengan sensor tegangan dan arus secara real-time, layar TFT untuk memberikan pemahaman materi tentang resistor dan kapasitor, serta sistem keamanan RFID. Metode penelitian yang digunakan meliputi studi lapangan, studi literatur, dan pengembangan sistem (SDLC). Hasil pengujian menunjukkan bahwa alat ini mampu memvisualisasikan perubahan tegangan akibat variasi nilai resistor dan kapasitor dengan akurasi yang baik. Media ini diharapkan dapat meningkatkan pemahaman konsep rangkaian listrik pada pelajaran fisika bagi siswa Sekolah Menengah Atas (SMA).

Abstract

Perancangan gazebo sehat dengan atap otomatis berbasis Internet of Things (IoT) dan notifikasi Blynk bertujuan untuk meningkatkan kenyamanan serta mendukung aspek kesehatan pengguna di ruang terbuka melalui sistem yang adaptif terhadap perubahan cuaca. Di wilayah tropis seperti Indonesia, cuaca yang tidak menentu dan paparan sinar matahari berlebihan dapat memengaruhi aktivitas serta kondisi fisik masyarakat. Paparan sinar matahari pagi pada pukul 06.00 hingga 10.00 diketahui membantu proses pembentukan vitamin D yang berperan penting bagi kesehatan tulang dan daya tahan tubuh. Oleh karena itu, sistem dirancang mempertahankan atap tetap terbuka pada rentang waktu optimal tersebut. Sistem ini menggunakan sensor hujan, sensor suhu (DHT), sensor cahaya (LDR), dan sensor ultrasonik yang terhubung dengan mikrokontroler ESP32 untuk membaca kondisi lingkungan secara real-time serta mengontrol mekanisme buka tutup atap secara otomatis sesuai parameter yang ditetapkan. Ketika terdeteksi hujan, peningkatan suhu, atau perubahan intensitas cahaya di luar batas aman, atap akan menutup sebagai bentuk perlindungan terhadap cuaca ekstrem dan menjaga ketahanan bangunan. Aplikasi Blynk diintegrasikan sebagai media pengontrolan jarak jauh dan sistem notifikasi berbasis internet. Hasil pengujian menunjukkan sistem bekerja responsif, stabil, dan sesuai perancangan.
