Abstract

The main issues faced by the target partner are the limited access to technical information regarding oil palm cultivation and the inefficiency of manual data management in the cooperative. To address these issues, the program proposes a solution in the form of the development of the Agrisawit application (for farmers) and the Cooperative Dashboard (for cooperative managers), both web and mobile-based, which is expected to facilitate farmers in accessing information related to oil palm cultivation, as well as making it easier for cooperative managers to manage data and communicate with members. The main objective of this community service program is to improve the operational efficiency and productivity of oil palm farmers at Koperasi Jaya Sempurna, Desa Pengabuan, Kecamatan Abab, Kabupaten PALI, South Sumatra Province, through the implementation of a digital-based information system. The program also includes digital literacy training for cooperative managers and members. Evaluation results show an 80% increase in application usage, a productivity increase in oil palm ranging from 45-90%, and a 90% improvement in the operational efficiency of the cooperative. This program is expected to have a sustainable positive impact on the cooperative and its members, and to serve as a model for the development of technology-based agribusiness in rural areas.

Abstract

Kemajuan dalam teknologi jaringan dan sistem monitoring kini menjadi aspek penting dalam meningkatkan efektivitas komunikasi dan pengawasan di berbagai bidang. Koperasi Mulia Sejahtera menghadapi tantangan berupa lambatnya respons dari operator jaringan saat terjadi gangguan koneksi internet atau ketika perangkat jaringan yang terhubung ke server mengalami masalah. Hal ini disebabkan oleh ketiadaan sistem notifikasi otomatis yang dapat memberikan peringatan secara langsung kepada operator. Penelitian ini bertujuan untuk merancang dan menerapkan sistem monitoring jaringan berbasis bot Telegram yang terintegrasi dengan perangkat Mikrotik. Penelitian ini menggunakan protokol ICMP (Internet Control Message Protocol) yang berfungsi untuk menyampaikan pesan terkait kesalahan jaringan dan kondisi-kondisi yang memerlukan tindakan segera. Protokol ini memanfaatkan perintah PING guna memeriksa status koneksi perangkat dalam jaringan. Sistem yang dikembangkan mampu mengirimkan notifikasi secara otomatis ke aplikasi Telegram saat terjadi gangguan atau saat koneksi jaringan kembali normal. Berdasarkan hasil pengujian yang dilakukan bersama operator jaringan dan pendamping Koperasi, sistem ini terbukti mampu memberikan notifikasi secara real-time ketika perangkat mengalami pemutusan atau pemulihan koneksi. Implementasi sistem ini diharapkan dapat meningkatkan responsivitas dan efisiensi kerja operator jaringan dalam menangani kendala konektivitas.

Berdasarkan hasil ujicoba lapangan, efektivitas Dongeng Antik “Sayang Teman” adalah sebesar 0,74 termasuk ke dalam kategori tinggi.Peneliti merekomendasikan kepada guru dan orang tua agar mau menjadi pendengar dan teman yang baik bagi anak-anak, sehingga mereka lebih terbuka dan merasa dihargai. ABSTRACT : Through this research, researchers developed an Anti Kekerasan (Antik) fairy tale book to introduce moral values to children. Antik fairy tale book is a pop-up book containing model for children. The book developed in this study is the Antik fairy tale series of phisical violence with the title “Sayang Teman”. Moral values introduced in the book Antik “Sayang Teman” is related to bad and good behavior. Bad behavior in the Antik fairy tale book is  illustrated into several forms of physical violenve such as hitting, kicking, and encouraging friends. Good behavior is described through the act of breaking up a friend who is fighting, admitting, a mistake and apologizing.  The objectives of this research include producing Antik fairy tales books to introduce moral values ​​of early childhood, knowing the feasibility of Antik fairy tales books to introduce moral values ​​of early childhood, and knowing the effectiveness of Antik fairy tales books to introduce moral values ​​of early childhood. The method used in this research is research and development. This research was carried out in four stages namely define, design, development, and dissemination. The subjects of this study were group B kindergarten students in sumedang district.  Based on the results of field trials, the effectiveness of the Antik”Sayang Teman”  fairy tale is 0.74 included in high category. Based on the results of field trials, the effectiveness of the Antik”Sayang Teman”  fairy tale is 0.74 included in high category. The researcher recommendeds that teachers and parents want to be good listeners and friends to children, so they are more open and feel valued.

Abstract

This paper investigates the impact of angular misalignment on splice loss across five distinct types of single-mode fiber (SMF), a critical factor in optical fiber network reliability. We regularly analyze splice loss at misalignment angles ranging from 0.1° to 1°, evaluating performance at both 1310 nm and 1550 nm wavelengths. Our findings consistently show that increasing angular misalignment directly causes a significant increase in coupling loss, with the SMF-28e+ showing the lowest susceptibility, recording losses of 0.7299 dB at 1310 nm and 0.672 dB at 1550 nm for a 1° angle. These detailed insights into the angular misalignment tolerance of various SMF types is crucial for enhancing the design and deployment of robust and efficient optical fiber networks, ultimately minimizing signal degradation and improving overall network performance.

Abstract

Early detection and accurate monitoring of methane (CH4) and carbon dioxide (CO2) at low concentrations are essential for industrial safety, environmental monitoring, and greenhouse gas mitigation. Conventional gas sensors, including electrochemical and semiconductor types, suffer from environmental sensitivity, frequent calibration needs, and limited long-term stability. Therefore, more stable, sensitive, and intrinsically safe sensing technologies are required, especially for high-risk environments. Fiber Bragg grating (FBG) sensors offer key advantages as passive optical devices that are immune to electromagnetic interference, compact, and capable of multiplexed operation. This study presents the design and characterization of a graphene-coated FBG sensor for low-concentration CH4 and CO2 detection. The FBG was fabricated using the phase mask technique, followed by cladding etching to enhance evanescent field interaction with the surrounding medium. A graphene layer was synthesized via chemical vapor deposition (CVD) and transferred onto the etched fiber surface to serve as the active sensing layer. Gas adsorption on graphene induces refractive index variations, producing measurable Bragg wavelength shifts monitored by a high-resolution optical interrogator. Experiments were conducted at concentrations up to 100 ppm under controlled temperature and humidity conditions. Results show sensitivities of 12.4 pm/100 ppm for CO2 and 9.7 pm/100 ppm for CH4, with strong linearity (R2 > 0.98), fast response time (< 15 s), low hysteresis, and good long-term stability. The proposed FBG-graphene sensor demonstrates strong potential for reliable real-time gas monitoring in industrial and environmental applications.
