Abstract

Indonesia sebagai negara agraris sangat bergantung pada sektor pertanian, terutama tanaman padi yang menjadi makanan pokok mayoritas penduduk. Tingginya konsumsi dan pertumbuhan penduduk membuat Indonesia masih bergantung pada impor, sehingga produksi beras harus ditingkatkan. Oleh karena itu, perlu dilakukan upaya untuk memetakan atau mengelompokkan daerah dengan tingkat produktivitas tanaman padi yang belum optimal di provinsi Jawa Timur. Data penelitian yang digunakan adalah data luas panen (ha), produksi (ton), dan produktivitas padi (ton/ha) yang bersumber dari website Badan Pusat Statistik Jawa Timur sebanyak 38 data kabupaten/kota dari Tahun 2020-2023. Data tersebut diolah menggunakan algoritma Fuzzy C-Means dilanjutkan penentuan cluster optimum menggunakan Silhouette Coefficient. Algoritma Fuzzy C-Means memungkinkan setiap data dapat memiliki derajat keanggotaan lebih dari satu cluster, sehingga menghasilkan pengelompokan yang lebih akurat dan representatif sesuai karakteristik data. Dari hasil uji 2 cluster hingga 10 diperoleh jumlah cluster optimum yaitu 6 cluster, dengan nilai Sihouette Coefficient 0,6902.

Abstract

This research will examine two important issues, first, issues related to ecology with all the scope of the problem. Second, issues related to economic independence. These two important issues are underwritten by Pondok Pesantren as a basis and value in solving ecological problems and economic independence. Theoretical studies of Islamic boarding schools' values originating from the treasures of "yellow yellow" are translated into practical matters. In summary, this research will also confirm that the treasures of the “Yellow Book” which contains a lot of ethical content can be implemented in more real actions, namely taking sides on ecological issues and issues of economic independence. This research uses a qualitative approach to the type of case study research. The thing that underlies the use of a qualitative approach in this research is because the researcher will explore the problem and develop a more detailed understanding of the phenomenon. Sources of data in this study were obtained from Caregivers/Leaders of the At Thoriq Ecology Islamic Boarding School, Management, Santri and the community around the Islamic Boarding School who were actively involved in the activity process. Data collection techniques were carried out by in-depth interviews, participatory observation and documentation. Qualitative data analysis techniques are carried out interactively, continuously until they reach completeness so as to obtain saturated data. Activities in data analysis are data reduction, data display and conculsion drawing/verification. The results of this study obtained information that products produced from agroecological activities developed by the At Thoriq Ecology Islamic Boarding School such as herbal teas, beauty products, organic rice, etc. are able to support Islamic boarding school activities so that Islamic boarding schools can be independent.

Abstract

PLTGU (Pembangkit Listrik Tenaga Gas Uap) adalah instalasi pembangkit listrik yang menggunakan tenaga gas dan uap untuk menghasilkan listrik. Bahan bakar yang digunakan pada PLTG berupa gas alam yang dibakar pada ruang bakar dengan udara dari atmosfer yang telah dikompres. Hasil dari pembakaran gas alam menghasilkan gas yang memiliki tekanan dan temperatur tinggi yang akan memutar turbin gas. Gas buang dari Gas Turbine (GT) masih memiliki tekanan dan temperature yang tinggi sehingga dimanfaatkan kembali sebagai media pemanas dari Heat Recovery Steam Generator (HRSG). Fungsi HRSG adalah untuk memanaskan air menjadi steam yang memiliki tekanan dan temperatur tinggi. Steam hasil dari HRSG akan memutar sudu-sudu turbin yang nantinya akan menghasilkan listrik. Adanya peranan penting HRSG, maka perlu dilakukan perhitungan efisiensi panas HRSG blok 1.2. Tujuan penelitian adalah mempelajari pengaruh variasi pressure drop terhadap efisiensi HRSG. Jumlah energi yang dibutuhkan untuk mengubah air menjadi uap dan juga energi yang disuplai dari gas buang turbin dapat diketahui dengan simulasi software ChemCAD. Jumlah energi yang hilang juga dapat diketahui dengan simulasi software ChemCAD 7.1.2. Hasil simulasi software ChemCAD dengan melakukan case study yang memvariasikan pressure drop pada alat LNG Exchanger didapatkan efisiensi panas HRSG 1.2 sebesar 51,296% dan heat losses sebesar 176852833,33 kJ/jam.

Abstract

This research includes a study of Badi’iyyah studies which is one of the types of studies in the ilm al-Balaghah. Ilm al-Badi’ is concerned with improving speech in terms of expression and meaning. One of the elements within the field of "Badi’iyah" is "Saja’," which involves concluding every two or more sentences with a single letter. Many rhetoricians have differed in their views on "Saja’" Some have called for avoiding it due to its complexity and resemblance to the poetry of the pre-Islamic era (Jahiliyya), while others have seen a rhetorical aspect in it after it was mentioned in the Quran. The objectives of this research are to identify the verses that contain "Saja’" and their rhetorical purposes. It becomes evident that this research is a qualitative study using the documentary method. The methodology used in this research is descriptive and rhetorical analysis, especially in the field of "Badiyah," to analyze the data. As a result of this research, the forms of verses containing "Saja’" have been identified, including the interrupted and parallel forms, along with their rhetorical purposes in Surah Al-Muzzammil, which involve improving their expressions, emphasizing certain aspects, and describing things through the mentioned "Saja’."
