Pengoptimalan Pendistribusian Jaringan Listrik Menggunakan Kruskal Algorithm
Full text linkPenelitian ini bertujuan untuk mengoptimalkan konfigurasi jaringan distribusi listrik pada PT PLN (Persero) Unit Induk Wilayah Sumatera Selatan, Jambi, dan Bengkulu (UIW S2JB) melalui Unit Pelaksana Pelayanan Pelanggan (UP3) Muara Bungo, khususnya di Unit Layanan Pelanggan (ULP) Muara Tebo yang mencakup kawasan Perumahan Pallima City Residence. Area tersebut mengalami ketidakseimbangan distribusi serta redundansi jalur yang menyebabkan inefisiensi penggunaan kabel dan peningkatan biaya instalasi. Untuk mengatasi permasalahan tersebut, penelitian ini menerapkan Algoritma Kruskal guna membentuk Minimum Spanning Tree (MST) yang mampu menentukan jalur distribusi paling efisien tanpa membentuk siklus. Data yang dianalisis meliputi titik-titik gardu (node), sambungan jaringan (edge), serta bobot berupa panjang kabel dalam meter. Melalui proses komputasi dan simulasi, hasil penelitian menunjukkan bahwa panjang total kabel dapat dikurangi dari 4.350 meter menjadi 3.877 meter, menghasilkan efisiensi sepanjang 473 meter. Selain itu, terdapat pengurangan jumlah sisi dari 82 menjadi 75, yang berarti eliminasi tujuh sambungan yang tidak efisien. Temuan ini membuktikan bahwa penerapan Algoritma Kruskal efektif dalam merancang ulang jaringan distribusi listrik yang lebih hemat, baik dari sisi penggunaan material maupun biaya operasional. Dengan demikian, metode ini dapat dijadikan referensi dalam perencanaan jaringan distribusi lainnya untuk meningkatkan efisiensi dan keandalan sistem kelistrikan

THE EFFECT OF LEARNING MEDIA “AL ARABIYYAH BAINA YADAIK VOLUME ONE" ON ARABIC LEARNING OUTCOMES OF 8TH GRADE STUDENTS AT MTSN 1 DELI SERDANG
Full text linkThis study specifically aims to examine the effect of Al-Arabiyyah Baina Yadaik learning media in the context of increasing Arabic language learning outcomes in class VIII students at MTsN 1 Deli Serdang. The phenomenon in the field shows that the dominance of conventional teaching methods that lack innovation and dependence on textbooks alone tend to create a passive learning environment, leading to a decrease in student motivation and learning outcomes. This condition emphasizes the imperative to adopt a more dynamic and technology-based learning approach, along with the demands of digital literacy in the contemporary era. By using a quantitative approach with an experimental design, this study validates the potential of Al-Arabiyyah Baina Yadaik as an interactive media designed for non-native learners, which holistically accommodates the development of four language skills (listening, speaking, reading, writing). The pilot test results showed strong evidence of a significant improvement in students' learning performance; the average score substantially increased from 64.5 to 97.5, followed by a drastic increase in the number of students who achieved the Minimum Completion Criteria (MCQ) from 7 to 18 individuals. In additional, field observations recorded a notable increase in the level of student activeness and enthusiasm in learning participation. The response from subject educators was also very positive, reflected in the percentage of media feasibility of 98% based on the evaluation of the aspects of appearance, material presentation, and benefits, all of which were categorized as “Very Feasible”. This finding firmly confirms the urgency of utilizing innovative and technology-adaptive learning media for optimizing the Arabic teaching and learning process which is not only effective, but also able to arouse students' intrinsic motivation and relevant to the dynamics of global education
IMPLEMENTASI PENDEKATAN FUNGSIONAL DALAM PEMBELAJARAN BAHASA ARAB MELALUI METODE COMMUNITY LANGUAGE LEARNING
Full text linkArabic language learning with a functional approach through the Community Language Learning (CLL) method aims to develop students' communication skills in real contexts. This approach emphasizes language as a tool for social interaction, not just grammatical rules. In practice, CLL encourages collaboration between students in a supportive atmosphere, thereby increasing self-confidence and practical understanding of the language. Teachers act as facilitators in creating participatory activities such as group discussions and role-playing. Technology integration in CLL also enriches the learning experience and encourages student independence. Real performance-based assessments are used to measure students' communication skills. In addition to linguistic aspects, this approach also fosters character values such as empathy and cooperation. Thus, the functional approach through CLL is expected to produce a generation that is communicative, collaborative, and sensitive to socio-cultural values in facing global challenges

Analisis Pelaksanaan Investigasi Kontak Tuberkulosis dengan Pendekatan 5M di Komunitas Masyarakat Sehat Sriwijaya Kota Palembang
No full textTuberculosis is a serious health problem that needs to be resolved immediately. Palembang City has the highest TB case finding rate in South Sumatra at 7,379 cases, which is equivalent to 31.73% of the total cases in South Sumatra. Contact investigation is the main strategy in detecting new cases and breaking the chain of transmission. The Healthy Sriwijaya Community in Palembang City is an important and integral part of the implementation of contact investigations. This study aims to analyze the implementation of contact investigation using a qualitative approach, employing in-depth interviews with twelve informants using Herrington Emerson's 5M (Man, Money, Materials, Method, Machines) theory. The results showed that the implementation of TB contact investigation was not optimal. The distribution of the cadre index has not been evenly distributed due to regional constraints, difficult access and distance, sufficient funds but untimely disbursement, logistical distribution obstacles, technical reporting constraints, and rejection due to community stigma. Strengthening education and active participation of various parties are needed to increase the coverage of contact investigations.Keywords: Community, Contact Investigation, Management, Tuberculosi
Model of Implementation of Islamic Communication Values in Public Services: A Participatory Study at Haji Hospital Medan
Full text linkEffective communication is a fundamental element in public service bureaucracies, especially in the healthcare sector, which is complex, dynamic, and directly impacts human life. However, many public institutions including government hospitals continue to face serious communication problems, such as misinformation, lack of empathy, and rigid bureaucratic interaction styles. This study aims to develop an implementable and contextual model of Islamic communication values within the bureaucratic system of public health services, using a participatory approach at RS Haji Medan, a government hospital with a strong Islamic identity. The research adopts a qualitative applied method with a Participatory Action Research (PAR) framework, involving hospital managers, medical staff, administrative personnel, and patients as active collaborators in diagnosing problems, formulating values, and testing the model. Findings show that while values such as shidq (truthfulness) and amanah (trustworthiness) are relatively applied, others like tabligh (clarity), fathanah (communicative intelligence), and ihsan (excellence with empathy) remain inconsistently practiced and depend largely on individual initiative. A five-component model was developed: (1) core Islamic values, (2) SOP for Islamic communication, (3) ethical communication guidelines, (4) internal training programs, and (5) value-based feedback systems. The pilot implementation in outpatient and emergency units demonstrated improvement in patient-staff communication, increased staff confidence, and enhanced institutional accountability. This study concludes that Islamic communication values can be translated into practical tools and procedures to humanize public service communication, especially in healthcare bureaucracies. The model is recommended for replication in similar institutions across Indonesia seeking to integrate spiritual and ethical dimensions into public service delivery
