Abstract

Teknologi akan menjadi pilihan yang diandalkan pada pertanian modern untuk meningkatkan efisiensi dan produktivitas, salah satu contoh adalah penggunaan rumah tanaman (planthouse), yang digunakan untuk kegiatan budidaya tanaman, dengan tujuan untuk melindungi tanaman dari hujan, angin dan hama, serta dapat mengontrol lingkungan secara optimal [1]. Peralatan yang dipakai untuk mengatur tingkat kelembapan udara yang merupakan salah satu parameter penting selain temperatur adalah humidifier [2]. Namun ternyata humidifier konvensional yang masih banyak dipakai seringkali menghadapi kendala seperti konsumsi energi yang tinggi, distribusi uap air yang tidak merata, serta perawatan yang komplek [3][4]. Kemudian teknologi humidifier ultrasonic vibration system muncul sebagai alternatif yang lebih efisien dan efektif dalam mengontrol kelembapan [5]. Teknologi ini menggunakan prinsip getaran ultrasonik untuk menghasilkan partikel uap air yang sangat halus, sehingga distribusi kelembapan menjadi lebih merata dan hemat energi [6]. Selain itu, humidifier jenis ini memiliki keunggulan dalam hal kebisingan dan minimnya pembentukan kerak mineral. Karena penerapan teknologi ini khususnya dalam konteks pengontrol kelembapan rumah tanaman masih relatif terbatas, maka dalam penelitian ini akan dibuat sebuah purwarupa humidifier ultrasonic vibration system dengan daya sembur yang dapat diatur, sehingga dapat mengontrol kelembapan yang lebih presisi, efisiensi energi yang lebih baik, serta peningkatan produktivitas tanaman dalam lingkungan rumah tanaman.

Abstract

Fish feed is one of the most important factors in fish farming and plays a crucial role in determining the success of the cultivation. One of the most commonly farmed fish species in the community is catfish. The feeding of catfish must be carefully managed to optimize their growth by providing feed accurately and regularly so that they can be harvested with maximum results. In this thesis research, a semi-automatic catfish feeder was designed to optimize the feeding process. The device is designed with a semi-automatic system so that when monitoring the catfish pond, farmers can simultaneously feed the fish. This device also uses a solar panel as an energy source to make it more efficient, especially in areas far from electrical sources. The feeder operates using Bluetooth transmission and can be controlled via a smartphone. It includes a feed dispensing system and a feed weight monitoring system, which displays the feed weight in grams on an LCD screen. On the smartphone, a parameter called "Feed Capacity" is displayed to indicate the amount of feed based on its height inside the feed container. This device has a load cell sensor with an average error of 0.5% and a servo motor with an average error of 0.6%.

Abstract

This study uses the Taguchi method to optimize the quality factor (Q-factor) of microring resonators (MRRs) for sensor applications. The MRRs are compact optical components widely used in biosensors and environmental monitoring due to their sensitivity to refractive index changes. The Q-factor, a key performance metric for MRRs, is significantly influenced by structural parameters such as ring radius (R), gap (g), waveguide width (W), and waveguide height (h). We employed a finite difference time domain (FDTD) simulation to model light propagation within the MRR and compute the corresponding Q-factor to identify the optimal combination of these parameters. An L9 orthogonal array (OA) is used in the Taguchi method to analyze each factor's influence with three levels systematically. The optimization resulted in a Q-factor of 6208.44, significantly higher than the baseline value, indicating a substantial improvement. Compared to previous works, this research highlights the advantages of combining FDTD-based electromagnetic modeling with statistical optimization, offering a structured yet efficient approach to MRR design. The proposed method enhances Q-factor performance and provides scalability for practical applications in biomedical and environmental sensing. These findings underscore the utility of Taguchi-based design in advancing the field of photonic sensor optimization.

Abstract

Abstrak—Microneedle merupakan sebuah teknologi pemberian obat yang diciptakan untuk meminimalisir rasa takut pasien terhadap sistem pemberian obat oleh tenaga medis, serta pemberian rasa nyaman kepada pasien dalam pemberian obat. Microneedle memiliki struktur berupa jarum berukuran mikro yang telah disarankan sebagai penghantar biomakromolekul dengan bahan yang digunakan adalah silikon (Si). Sebelum dilakukannya fabrikasi, para peneliti perlu adanya beberapa acuan berupa simulasi agar tidak terlalu jauh parameter yang diharapkan. COMSOL Multiphysics merupakan sebuah aplikasi yang dapat digunakan sebagai simulasi untuk menampilkan hasil analisis stationary dan linier buckling.. Pada penelitian ini penulis melakukan perancangan dan simulasi microneedle 3 geometri dengan variasi ukuran ujung tip yaitu 20, 25 dan 30 µm serta force yang diberikan 0 – 2 mN. Pada analisis stationary yang dilakukan yaitu dengan menampilkan hasil stress rendah dan displacement hingga menuju lapisan epidermis. Analisis buckling terdapat 3 studi yang dilakukan yaitu dengan menampilkan nilai axial load, buckling load dan banding load. Pada uji ketahanan tekuk diberikan preasure sebesar gaya penyisipan kulit yaiut 3,18 MPa, serta pada analisis buckling load terdapat nilai critical load factor, jarum dikatakan aman tidak terjadi tekuk bila CLF>1. Didapatkan rekomendasi geometri pada penelitian ini yaitu geometri II dengan diameter tip 20 µm menampilkan nilai stress 7,7 x 106 N/m2 dengan displacement 192 µm ketika diberikan force 1,6 mN pada study stationary. Pada analisis axial load menghasilan nilai 2.62 X 106 N/m2 dengan nilai critical load factor 4243,3 dimana CLF>1 maka dikatakan aman dan tidak terjadi tekuk pada analisis buckling study, serta menghasilkan nilai critical buckling force 16,95828 N dari hasil perkalian Fskin. Serta hasil nilai bending yaitu 1,7 X 10w N/m2 . Kata kunci — microneedle, epidermis, transdermal, COMSOL Multiphysics, silikon

Abstract

The development of technology in the era of the Industrial Revolution 4.0 requires an increase in technological literacy from an early age, including at the junior high school level (SMP). One way to introduce the concept of technology is through automation and robotics education. Based on this, the lecturer and student team from the Electrical Engineering Study Program at the Faculty of Engineering, Garut University, conducted community service activities in the form of education and robotics awareness to 8 MTsN 1 Garut students on May 24, 2025, with a total of 69 participants. The purpose of this activity is to foster interest, insight, and basic understanding of students about the automation system and robotics technology. The method of implementing the activity consists of the delivery of automation and robotics materials, question and answer sessions, and demonstrations of tools in the form of Line Follower robot, robot soccer, and heavy monitoring and sheep height. The results showed high levels of student participation and enthusiasm. Students look active in asking questions and trying to run robots directly. The evaluation was carried out with a satisfaction questionnaire, which showed positive results: satisfaction with the relevance of the topic of 77.33%, how to deliver 80%resource persons, the implementation of activities 78.67%, and the benefits of activities 85.33%. It can be concluded that this educational activity can increase student awareness and interest in automation and robotics technology, and can be applied to become an effective and fun Stem learning model at the junior high school level.
