Abstract

The transmission lines generally using conductor with ACSR (Aluminium Conductor Steel Reinforced) which has limited temperature until 90 degrees. In this present time, the need of electricity is increasing rapidly; considering from that problem, we need to increase the capacity of transmission line by optimizes the capacity of line conductor from the transmission line before. The main problem of optimizing the transmission line are the tension and sagging of the conductors become bigger. Based from this situation the research is conducted to know about the characteristic of the alteration of current line to tension and sagging of the conductors. Therefore, the result of the research can be useful in designing the structure construction of transmission line which suitable to the conductor's characteristic. As a simulation model, Paiton-Krian 500 kV transmission line is used. The data, including the data of ACSR conductor, are collected from the field. The conductor's temperature is calculated using heat-balance method. Ruling Span method is used to measure the length of equivalent span. Mean while the Catenary method is used to measure the conductor's tension and sagging. In conclusion, it can be seen that the alteration of line current from 10 Ampere to 850 Ampere will cause the conductor temperature increase 125.94%, the tension decrease 36,38% and the sagging increase 26.82%. Abstract in Bahasa Indonesia : Saluran transmisi udara umumnya menggunakan konduktor jenis ACSR (Alumunium Conductor Steel Reinforced) yang memiliki batas temperatur kerja yang diizinkan sebesar 90 C. Mempertimbangkan peningkatan kebutuhan tenaga listrik yang pesat akhir-akhir ini, maka usaha untuk meningkatkan kapasitas saluran transmisi dilakukan dengan mengoptimalkan kapasitas hantaran arus dari saluran transmisi yang telah ada. Permasalahan utama dari peng-optimalan saluran transmisi tersebut adalah tegangan tarik dan andongan yang timbul pada konduktor tersebut menjadi lebih besar, oleh karena itu penelitian ini bertujuan untuk mengetahui karakteristik perubahan arus saluran terhadap tegangan tarik dan andongan konduktor, dengan demikian diharapkan dari hasil penelitian ini akan berguna untuk membangun struktur konstruksi saluran transmisi yang sesuai dengan sifat dari konduktor tersebut. Sebagai model simulasi digunakan saluran transmisi tegangan ekstra tinggi 500 kV jalur Paiton-Krian dengan menggunakan data-data konduktor ACSR yang sesuai dengan yang ada di lapangan. Temperatur konduktor dihitung berdasarkan persamaan keseimbangan panas. Metode Ruling Span digunakan untuk menentukan panjang span equivalen. Sementara itu metoda Catenary digunakan untuk menghitung tegangan tarik dan andongan konduktor tersebut. Berdasarkan hasil dari penelitian ini dapat disimpulkan bahwa dengan adanya perubahan arus saluran dari 10 Ampere menjadi 850 Ampere mengakibatkan terjadinya peningkatan temperatur konduktor sebesar 125.94 % dan penurunan tegangan tarik sebesar 36.38 % serta terjadi peningkatkan pada andongan sebesar 26.82 %. Kata kunci: kuat hantar arus, saluran transmisi, ACSR.

Abstract

Islamic boarding schools (pesantren) play a significant role in character education and religious learning in Indonesia. Effective management relies on strong leadership and interpersonal communication between administrators and educators. Communication patterns influence decision-making, conflict resolution, and overall institutional effectiveness. In pesantren, the relationship between mudir (leader) and ustaz (teachers) is crucial for maintaining discipline and achieving educational goals. This study aims to describe the pattern of interpersonal communication between mudir and ustaz in Pondok Pesantren Darul Hadits Palembang and analyse its influence on the management of the pesantren. Using a sequential mixed method, the study started with a quantitative approach to identify communication patterns, followed by qualitative analysis for deepening. Results showed the dominance of open (64%) and assertive (63%) communication patterns, reflecting transparency, assertiveness, and clarity of instructions from the mudir. The communication structure is hierarchical, with mudir as the main authority. The implications of these findings suggest that open and assertive communication patterns, supported by the mulazamah-based education system, strengthen interpersonal relationships and the effectiveness of pesantren management

Abstract

adicalism in the mosque environment is one of the social phenomena that needs serious attention. Mosques, as centres of worship and Islamic learning, can be effective means of spreading moderate ideology, but are also vulnerable to infiltration of radical ideology. This phenomenon occurs in various cities in Indonesia, including Palembang. This research aims to analyze the penetration patterns of the spread of radical ideology through recitation activities in Palembang City mosques. This research uses a qualitative approach with a case study method. The data source in this research, namely the primary source, is the chairman of the mosque takmir, chairman of the Idarah and Imarah section, as the administrator who has the authority to make decisions regarding mosque management such as the recitation schedule at the mosque. The secondary source of this research will be directed at the mosque congregation who are involved in every activity held at the mosque. Data collection in this research used interview, documentation and observation techniques.  The stages of the data analysis process include data collection, data reduction, data presentation, and drawing conclusions and verification. The results of this research can be concluded as follows: The patterns of penetration of radical Islamic ideology from Salafi followers among residents and mosque congregations in Palembang include, among others, through the spread of Salafi ustadz as Friday preachers, through the distribution of books that have been explained. (syarah) from Salafi ulama circles, and through the distribution of message and video posts on Whatsapp Group.
