Abstract

This paper discusses the role of kiai in the decision-making process of pesantren development innovation and the impact of pesantren development innovation on learning activities in pesantren. This paper used qualitative research. Data were obtained through interviews and participatory observation. Data analysis was conducted using an interactive model including data collection, data reduction, data presentation and conclusion drawing. The findings of this study are the role of the main kiai or founder of the pesantren in the form of giving decisions on innovations implemented by Kiai Basyar Rohman. He is a figure who is considered to play a role as a carrier of change, an agent of reform, as well as an implementer of innovation in accordance with the qualifications and abilities he has from his previous experience managing pesantren. The success of pesantren innovations carried out was supported by all internal parties of the pesantren including santri and other ustaz. The impact of the development of pesantren education implemented by Kiai Basyar made Pesantren Manbaul Hikmah a combination pesantren (hybrid pesantren between modern and salaf) which did not eliminate the main characteristics of its salaf. In the morning, santri study in formal schools, and when they return to the pesantren, they carry out routine pesantren activities as usual, and at night they attend madrasah diniyah.

Abstract

Background: Dr. H. Kumpulan Pane Regional Hospital, Tebing Tinggi City has 213 beds with a potential medical waste calculation of around 682 kg per day, but data from the last 3 months shows that B3 waste at Dr. H. Kumpulan Pane Regional Hospital is 79,142/kg/month or approximately 2,638 kg/day. Objectives: to analyze the factors that influence the management of solid media waste of hazardous and toxic materials at RSUD.Kumpulan Pane, Tebing Tinggi City. Research method: This research is a quantitative descriptive research with a cross sectional design. Results: In this study, momentary measurements were carried out on independent variables and concurrent variables (Point time approach), with the T test and F test, the results obtained were that the knowledge factor of sanitation officers did not affect the management of B3 medical solid waste, the infrastructure factor did not affect the management of B3 medical solid waste, the technical guideline factor did not affect the management of B3 medical solid waste, but the funding factor affected the management of B3 medical solid waste at the Hospital. Conclusion: The most influential factor among the four variables is the funding factor variable with a Beta value of 0.96.

Abstract

This paper introduces a hybrid optimization approach that combines genetic algorithms with gradient descent for effective nonlinear function approximation in highdimensional data. Traditional methods struggle with computational efficiency and accuracy in such complex spaces. By integrating genetic algorithms to provide a global search strategy with gradient descent for finetuning, the proposed method achieves faster convergence and improved accuracy. Simulations and case studies demonstrate its effectiveness in applications like data mining, image recognition, and financial modeling.

Abstract

Kelincahan merupakan komponen fisik yang sangat penting dalam olahraga bulutangkis, hal ini dikarenkan agar para pemain dapat bergerak ke segala arah dengan cepat dan tepat untuk mengejar ataupun megembalikan shuttlecock ke daerah lapangan lawan. Penelitian ini bertujuan untuk mengetahui pengaruh dari latihan footwork dan latihan shadow terhadap kelincahan atlet tim bulutangkis PB. Setia Putra. Metode penelitian yang digunakan adalah eksperimen dengan menggunakan pretest-postest design. Populasi dalam penelitian ini adalah seluruh atlet tim bulutangkis PB. Setia Putra, dengan menggunakan teknik sampling yaitu total sampling. Maka sampel dalam penelitian ini adalah seluruh atlet bulutangkis PB. Setia Putra sebanyak 20 orang. Instrumen yang digunakan dalam mengumpulkan data adalah tes kelincahan dengan boomerang run. Hasil penelitian berkesimpulan bahwa: (1) Terdapat pengaruh yang signifikan latihan footwork terhadap kelincahan atlet bulutangkis PB. Setia Putra, karena nilai thitung > ttabel (12,67 > 2,10), (2) Terdapat pengaruh yang signifikan latihan shadow terhadap kelincahan atlet bulutangkis PB. Setia Putra, karena nilai thitung > ttabel (14,84 > 2,10), (3) Latihan shadow memberikan pengaruh lebih signifikan terhadap kelincahan atlet bulutangkis dari pada latihan footwork. Bagi para pelatih, pembina, dan juga atlet agar dapat menerapkan prinsip-prinsip latihan dalam latihan fisiknya, khususnya jika ingin meningkatkan kelincahan dapat menggunakan bentuk latihan shadow. Khususnya bagi para peneliti yang hendak meneliti dengan variabel yang sama, dapat mencoba untuk membandingkan dengan bentuk latihan yang lain.
