Abstract

Oven tembakau berperan penting dalam proses pengeringan daun tembakau, namun risiko kebakaran akibat panas berlebih dan gangguan sistem pemanas dapat menimbulkan ancaman serius. Penelitian ini bertujuan merancang dan mengembangkan Sistem Pendeteksi Kebakaran dan Pemantauan Oven Tembakau Berbasis IoT untuk mengurangi risiko suhu berlebih dan api tersebut serta meningkatkan efisiensi pengelolaan. Sistem ini memanfaatkan sensor suhu dan api yang terhubung ke platform IoT untuk pemantauan kondisi oven secara real-time. Ketika suhu melebihi 70°C atau terdeteksi adanya api, setatus monitor menjadi terdeteksi api serta alarm akan berbunyi dan notifikasi langsung dikirim melalui Telegram untuk memastikan tindakan pencegahan segera dilakukan. Sistem ini sangat membantu petani dalam menjaga keamanan dan pengawasan oven tembakau selama proses pengeringan berlangsung. Hasil pengujian dan implementasi menunjukkan bahwa sistem ini mampu mendeteksi dan merespons kondisi berbahaya dengan tingkat keberhasilan 100%, sehingga dapat meningkatkan perlindungan terhadap risiko suhu berlebih dan penanganan awal terjadinya kebakaran, kerusakan peralatan, dan gangguan pada sistem pemanasan.

Abstract

This research aims to review the characteristic of the nature of electricity polymer material poly(3-hexylthiophene) P3HT against increasing efficiency solar cells based on dye-sensitized solar cells (DSSC). The testing sample has done electricity P3HT el-kahfi 100/ I-V meter. The optical properties use spectrophotometer UV visible 1601 PC and characterizing IV DSSC use Keithley 2600 a type. The absorbance of P3HT polymer 1% has an absorption peak in the wavelength range of 300-650 nm. Thus the P3HT polymer material can absorb light in the visible wavelength range. The electrical properties of P3HT 1% indicate that the material has a response to light. In bright conditions, P3HT 1% shows a conductivity of 3.7x10-3Ω-1m-1 and in dark conditions 2.2x10-3Ω-1m-1. Meanwhile, Pt (Hexacloroplatinic IV) Platina as the opposing electrode can improve the performance of DSSC, which is because Pt (Hexacloroplatinic IV) functions as a catalyst to accelerate the redox reaction with electrolytes. The use of P3HT 1% can improve DSSC performance. DSSC using 1% P3HT and using Pt (Hexacloroplatinic IV) as the opposing electrode produced an efficiency value of 1.8x10-2%.

Abstract

This study aims to cluster and visualize the earthquake data on a geographical map to determine earthquakes' characteristics using the k-means algorithm. Cluster analysis using the k-means algorithm was carried out on the earthquake data. K-means algorithm is familiar and is one of the well-known techniques to have been applied in cluster analysis. One of Its advantages in cluster analysis is scaling large datasets, for example, earthquake data. The data used in this study is earthquake data in the West Nusa Tenggara from 1991 to 2021. Applying the proposed k-means algorithm, the optimal number of clusters (k) used in this clustering is 2, based on the highest silhouette score of 0.749. The cluster analysis on the geographical map showed that the epicenters of the earthquakes were pretty spread out before 2018, and the number of earthquakes in the eastern region of West Nusa Tenggara is more than in the western area. However, in 2018, the clusters were all bunched in the northern Lombok region. There were a few earthquakes in the west region in 2018, but they happened before August 5. Even after 2019, most earthquakes continue to occur, with the epicenters clustered close to the northern Lombok region

Abstract

Decision Support System is a computer system that processes data into information to make decisions regarding specific semi-structured problems. It is specially developed to support solutions for unstructured management issues to enhance the quality of decision-making. The selection of potential thesis advisors at Hamzanwadi University's Informatics Engineering program is currently done by directly choosing an advisor while considering individual criteria or by seeking advice from peers. However, this direct selection method sometimes overlooks crucial aspects that should be prioritized. This research aims to construct a web-based Decision Support System (DSS) to assist final-semester students in the Faculty of Engineering at Hamzanwadi University in selecting their thesis advisors. The methodology employed in this Decision Support System is the Weighted Product method, which enables the calculation and comparison of multiple factors during the decision-making process. Factors analyzed in this study encompass the instructors' competency areas and the number of students they supervise. The utilization of this Decision Support System is expected to aid students in choosing an appropriate and fitting thesis advisor according to their needs. Moreover, the Decision Support System is anticipated to aid the faculty in providing information about potential thesis advisors before students finalize their choices. This research is expected to contribute to and benefit the development of information technology in the education sector

Abstract

Increasing competence is very necessary for SMK students to improve their insight and knowledge in a world with very rapid technological developments. Increasing competence certainly supports students in preparing for the world of work and becomes a provision for higher education with appropriate fields of competence. In this case, the Computer Engineering Study Program of Hamzanwadi University takes a role in community service by providing Internet of Things (IoT) training to support the competence of vocational students. The competency improvement training was given to students of SMKN 1 Pringggabaya, East Lombok, with a total of 40 students. The training provided was in the form of IoT implementation for intelligent homes, in the form of Light Emitting Diode (LED) control as a substitute for house lights connected to the ESP32 microcontroller and several electronic components, while monitoring and controlling was carried out using a smartphone connected to the internet. In its implementation, the method used is to provide an understanding of the knowledge of IoT, and the application of IoT in several fields, followed by trying to practice the implementation of a smart home which is also implemented and tested directly by students. The results obtained from the training show students' interest in IoT implementation and enthusiasm for understanding IoT implementation now.

Abstract

Solar cells are devices composed of solar panels that convert light into electrical energy. Conventionally, energy is primarily derived from fossil fuels, which are non-renewable resources. Consequently, many researchers have sought alternative sources of energy. One such innovation is the Dye-Sensitized Solar Cell (DSSC). This study aims to investigate the effect of Antigonon leptopus flower dye as an active material in Dye-Sensitized Solar Cells (DSSC). The absorbance testing was conducted using a UV-Visible Spectrophotometer (1601 PC), while current and voltage (I–V) measurements were carried out using a Keithley instrument. The results showed that the natural dye extracted from the leaves of Antigonon leptopus exhibited an absorbance spectrum in the range of 200–800 nm. These findings suggest that Antigonon leptopus has potential as a natural sensitizer material for application in Dye-Sensitized Solar Cells (DSSC).
