Abstract

ABSTRAKBatu pecah berukuran 2,38 mm – 4,75 mm tidak digunakan dalam campuran beton. Jika campuran beton dirancang menggunakan batu pecah ini sebagai agregat kasar, maka campuran beton yang dihasilkan diduga tidak akan mengalami segregasi untuk semua kelecakan, lebih homogen, dan jika diberi bahan tambahan superplasticizer diduga dapat dengan mudah berperilaku sebagai campuran beton memadat mandiri. Penelitian ini dilakukan untuk membuktikan dugaan tersebut. Penelitian dilakukan dengan kuat tekan rencana 30 MPa, slump 40 mm dan 100 mm, tanpa dan dengan bahan tambahan superplasticizer dengan dosis 1% dan 1,5%. Perancangan campuran beton dengan cara Dreux menggunakan faktor granular 0,40; 0,45; 0,50; dan 0,55. Pengujian kuat tekan pada benda uji silinder diameter 10 cm dan tinggi 20 cm membuktikan bahwa dugaan tersebut adalah benar, dan perancangan campuran beton dengan memperlakukan batu pecah berukuran 2,38 mm – 4,75 mm sebagai agregat kasar dapat dilakukan untuk faktor granular 0,40 – 0,50.Kata kunci: batu pecah berukuran 2,38 mm – 4,75 mm,agregat kasar,superplasticizer ABSTRACT2.38 mm – 4.75 mm crushed aggregate size is not used in concrete mix. If this crushed aggregate is used as coarse aggregate, the resulting concrete mix is assumed will not segregate in all workability, more homogeneous, and it will behave easily as self-compacting concrete by adding superplasticizer. This research was conducted to prove these assumption. Concrete mix with compressive strength of 30 MPa, 40 mm and 100 mm slump is made using Dreux method with granular factor 0.40; 0.45; 0.50; and 0.55. The doses of superplasticizer is 1% and 1.5% by cement weight. Compressive strength tests of 10 cm diameter and 20 cm height cylinder diameter showed these assumption is true, and concrete mix can be designed using granular factor 0.40 – 0.50.Keywords: 2,38 mm – 4,75 mm crushed aggregate size, coarse aggregate, superplasticizer

Abstract

This study aims to evaluate the challenges and strategies faced by teachers in translating the text of the Ta'lim Al-Muta'allim book into Indonesian and to analyze the effectiveness of the learning approach applied at the Al-Mujahidin Gerung Islamic Boarding School. The Ta'lim Al-Muta'allim book by Imam Az-Zarnuji is one of the classic works that has a strategic position in the world of Islamic education and has been the main reference in shaping the character and ethics of learning for students for centuries. The process of learning this book faces its own challenges, especially in terms of translating and understanding classical Arabic texts that require special competence from teachers in mastering both languages. This study uses a qualitative method with a case study approach through classroom observation, in-depth interviews with ustadz, and analysis of learning documents. The results of the study indicate that the main challenges faced include the complexity of classical Arabic language structures, the difficulty of finding appropriate equivalents for philosophical concepts, and the diversity of Arabic language proficiency levels among students. The strategies implemented by the teachers through an individual approach with a literal translation method accompanied by contextual explanations, and strategies through cooperative learning methods with group discussions, proved effective in achieving learning objectives. The effectiveness of the translation strategy is reflected in the high level of students' understanding of abstract concepts, the consistency of terminology that was successfully maintained, and the success of transferring educational values into the context of modern student life.

Abstract

ABSTRACT Microenterprises play a strategic role in improving rural community welfare, particularly through the utilization of local resources. Jaddung Village, Pragaan Subdistrict, Sumenep Regency, has abundant spice potential, yet it has not been fully utilized as a source of economic income. This community engagement program aimed to develop microenterprises through culinary innovation with the “Mandala” instant fried rice seasoning product while empowering local communities, especially housewives and youth. The method used was Participatory Action Research consisting of several stages: identifying local potential, conducting training on instant seasoning production, providing entrepreneurship mentoring, implementing digital marketing strategies, and evaluating program sustainability. The results showed that community partners successfully produced hygienic instant seasoning products with a unique blend of Madurese and Thai flavors, packaged in simple but marketable designs. SWOT analysis revealed that the strengths of the product lie in its natural ingredients and distinctive taste, weaknesses in limited capital and production scale, opportunities in the growing trend of healthy instant food, and threats from established commercial competitors. The program had a positive impact on improving production skills, entrepreneurial knowledge, and household income. In conclusion, the Mandala seasoning innovation proved effective as a microenterprise model based on local culinary resources and has the potential to be replicated in other villages with continued support from government and higher education institutions. ABSTRAK Usaha mikro memainkan peran strategis dalam meningkatkan kesejahteraan masyarakat pedesaan, terutama melalui pemanfaatan sumber daya lokal. Desa Jaddung, Kecamatan Pragaan, Kabupaten Sumenep, memiliki potensi rempah-rempah yang melimpah, namun belum sepenuhnya dimanfaatkan sebagai sumber pendapatan ekonomi. Program pemberdayaan masyarakat ini bertujuan untuk mengembangkan usaha mikro melalui inovasi kuliner dengan produk bumbu nasi goreng instan "Mandala" sambil memberdayakan masyarakat lokal, terutama ibu rumah tangga dan pemuda. Metode yang digunakan adalah Penelitian Tindakan Partisipatif yang terdiri dari beberapa tahap: mengidentifikasi potensi lokal, mengadakan pelatihan produksi bumbu instan, memberikan bimbingan kewirausahaan, menerapkan strategi pemasaran digital, dan mengevaluasi keberlanjutan program. Hasil menunjukkan bahwa mitra komunitas berhasil memproduksi produk bumbu instan higienis dengan perpaduan rasa Madura dan Thailand yang unik, dikemas dalam desain sederhana namun menarik. Analisis SWOT mengungkapkan bahwa kekuatan produk terletak pada bahan alami dan rasa yang khas, kelemahan pada modal dan skala produksi yang terbatas, peluang pada tren makanan instan sehat yang berkembang, dan ancaman dari pesaing komersial yang sudah mapan. Program ini memiliki dampak positif dalam meningkatkan keterampilan produksi, pengetahuan kewirausahaan, dan pendapatan rumah tangga. Kesimpulannya, inovasi bumbu Mandala terbukti efektif sebagai model usaha mikro berbasis sumber daya kuliner lokal dan memiliki potensi untuk direplikasi di desa-desa lain dengan dukungan berkelanjutan dari pemerintah dan lembaga pendidikan tinggi.
