Abstract

In this article, the Ising model has been modified to simulate the effect of particle size on magnetic nanoparticles properties especially hole-doped manganites. The objective of this research is to give an insight and clear understanding about magnetic nanoparticles especially the effect of the particle size. The model considers common accepted magnetic nanoparticles theoretical model where each particle consists of core and surface/boundary part. The model mimics the particles size as a clusters or group of spins. The spins were designated as either core or boundary particles and differs for their exchange energy. The model predicts magnetization, coercivity, hysteresis and magnetic characteristics of core and boundary of the nanoparticles. The results are in a good agreement qualitatively with experimental results. The model also gives insight to the micro-states of the spin at each clusters for zero-field-cooled experiment.

Abstract

Kecenderungan pada dewasa ini, ada berbagai masalah yang muncul pada bidang pertanian. Salah satu dari masalah tersebut yang paling utama adalah keterbatas lahan untuk ditanami. Perlu diketahui bahwa dengan peningkatan jumlah penduduk dan pembangunan, ketersediaan lahan pun menjadi berkurang secara signifikan. Rumah kaca menjadi salah satu jawaban dari masalah tersebut. Rumah kaca pada jaman ini sudah dilengkapi dengan sistem kendali dan monitoring sebagai salah satu improvement rumah kaca cerdas. Tentunya Rumah Kaca cerdas seperti demikian membutuhkan energi listrik yang handal dan berkelanjutan untuk mendapatkan fungsi rumah kaca cerdas yang baik. Penelitian ini melakukan analisis, simulasi, desain, dan implementasi nyata sistem pendayaan energi listrik untuk rumah kaca tersebut. Pendayaan energi listrik tersebut akan didayai dengan energi terbarukan yaitu energi matahari dengan teknologi PV pada Pembangkit Listrik Tenaga Surya. Sehingga dibutuhkan identifikasi beban-beban dan kebutuhan listrik yang ada pada rumah kaca, pemilihan desain sistem energi rumah kaca, penentuan spesifikasi peralatan-peralatan yang diperlukan, serta implementasi pendayaan energi listrik rumah kaca tersebut

Abstract

Greenhouse is a place to grow plants where the micro climate is controlled to achieve the best possible climate to grow plants. The micro climate involve three different states namely the state of the outside and inside air of the greenhouse and the state of the soil where the plants grow. The focus of this research is to design monitoring system which able to monitor those three states. The system is built based on four temperature and humidity sensors, two microcontoller ESP32, communication protocol MQTT and Node-RED. The sensors have been carefully selected in order to obtain particular measurements. The system has been tested for one day. The system is able to show the measurement data and record it in .csv format. The system is able to picture qualitatively the dynamics of weather and watering inside and outside of the greenhouse.

Abstract

This community service establishes a collaborative effort between Parahyangan Catholic University and SMAK 1 BPK PENABUR Bandung to enhance the TechnoCreator program through community involvement. The program aims to enhance students' understanding of electronics by incorporating advanced technologies like the Internet of Things (IoT) and machine learning. It also introduces the concepts of Industry 4.0 and technopreneurship. The research entailed conducting a series of focused group talks, often known as focus groups, to ascertain the material and learning requirements. Additionally, an extracurricular curriculum for robotics was developed. The outcomes are the creation of novel educational programs, maintenance of guest lectures, strategic planning for the construction of an ESP32-based Internet of Things kit, the design of a prototype industrial automation system, and the implementation of a supplementary robotics program aimed at enhancing students' preparedness for advanced studies in electrical engineering. The activity also seeks to facilitate the transfer of students from secondary education to college. The result implies that this project effectively enhances student learning experiences and can be used as a blueprint for comparable technology education programs in the future.
