ANALISIS PERBANDINGAN PENGGUNAAN KAWAT LOW TENSILE DAN HIGH TENSILE UNTUK PERKUATAN LERENG

Ato patoni — 2025-11-20

Penelitian ini bertujuan untuk menganalisis perbandingan penggunaan kawat low tensile dan high tensile untuk perkuatan lereng. Penelitian ini membandingkan kekuatan tarik, deformasi, dan stabilitas lereng yang menggunakan kawat low tensile dan high tensile. kawat high tensile memiliki kekuatan tarik yang lebih tinggi dan deformasi yang lebih kecil dibandingkan dengan kawat low tensile. Namun, kawat low tensile masih dapat digunakan untuk perkuatan lereng dengan kemiringan yang tidak terlalu curam dan beban yang tidak terlalu besar. Penelitian ini dapat membantu dalam pemilihan jenis kawat yang tepat untuk perkuatan lereng berdasarkan kondisi lereng dan beban yang diharapkan.

This system is expected to assist management in managing fleet operational schedules more effectively and efficiently and facilitate passenger ticket reservations. Test results for PO. Sudiro Tungga Jaya's web-based scheduling information system achieved the expected results, achieving a 100% system success rate.

Pengaruh Substitusi Serbuk kaca Sebagai Pengganti Pasir Terhadap Kuat Tekan Bata Ringan

bhyta pratama yuvi Anggraeni — 2025-11-20

Perkembangan zaman di bidang ilmu pengetahuan terus mengalami peningkatan setiap tahunnya. Perkembangan pengetahuan yang semakin pesat memunculkan berbagai ide baru, khususnya dalam bidang konstruksi. bahan bangunan yang ramah lingkungan dan efektif, salah satu kemajuan tersebut adalah pemanfaatan serbuk kaca sebagai pengganti pasir dalam pembuatan bata ringan. Limbah kaca, yang menyumbang sekitar 2,3% dari total sampah nasional, memiliki potensi yang signifikan untuk digunakan kembali dalam mengurangi pencemaran lingkungan. Penelitian ini untuk menilai dampak pemanfaatan serbuk kaca terhadap kuat tekan dan berat jenis bata ringan. Serbuk kaca digunakan dalam tingkat presentase 0%, 10%, 20%, 30%, 40%, dan 50% berdasarkan berat agregat halus pasir. Hasil kuat tekan menunjukkan presentase 0% sebesar 2,08 Mpa, 10% sebesar 2,27 Mpa, 20% sebesar 2,55 Mpa, 30% sebesar 2,18 Mpa, 40% sebesar 2,00 Mpa, dan 50% sebesar 1,91 Mpa. Kuat tekan maksimum terjadi pada presentase serbuk kaca 20% yaitu sebesar 2,55 Mpa, yang memenuhi standart bata ringan non-struktural berdasarkan SNI. Selain itu, emakin tinggi presentase serbuk kaca dapat menambah berat jenis bata ringan tetapi masih sesuai standart SNI. Dapat disimpulkan bahwa Presentase ideal serbuk kaca sebagai pengganti pasir dalam pembuatan bata ringan adalah 20%.

Sistem Informasi Pengelolaan Data Simpan Pinjam Koperasi

sukadi sukadi — 2025-11-20

This researchhis motivated by the large number of cooperativessin Indonesia, consisting of consumerccooperatives, producer cooperatives, serviceecooperatives, savings and loan cooperatives, and also multi-purpose cooperatives (KSU) [3]. Where one of the functions of cooperatives is to develop theepotential and economic capabilities of members and the community. In carrying out its activities, of course, cooperatives need a system to process their data. This research aims to create a system design for processing savingssand loan data in savings and loan cooperatives or multi-purpose cooperatives. The researchhmethod used is the SystemnDevelopment Life Cycle (SDLC) waterfall method. This SDLC waterfall is one of the modeling of the SDLC method which is systematic or measurable from the initialsstage to the finalsstage. The results of this study can be used as a reference in creating a system for processing savings and loan data in savings and loan cooperatives and also multi-purpose cooperatives, although in creating the system the number of tables used may be different in each savings and loan cooperative and also multi-purpose cooperative

PERANCANGAN POLIMER KOMPOSIT DENGAN SERAT TEBU DAN FIBER GLASS UNTUK PENINGKATAN KEKUATAN TERHADAP UJI TARIK

Sutrisno . — 2025-11-20

This study investigates the effect of varying weight fractions of sugarcane fiber and fiberglass on the mechanical properties of polyester resin-based composite, with a focus on improving tensile strength. Sugarcane fiber, a lignocellulosic natural reinforcement with a length of 3 cm, was used alongside fiberglass as a synthetic reinforcement to evaluate the performance of hybrid composites. Specimens were fabricated using the hand lay-up method with five combinations of sugarcane fiber (0–10%) and fiberglass (0–10%), while the polymer resin and catalyst comprised 90% of the total composite weight. Tensile testing was conducted according to ASTM D638-01 using a Universal Testing Machine. The evaluated parameters include maximum tensile stress, strain, and elastic modulus. Experimental results showed the highest tensile strength of 88,186 MPa at 0% sugarcane fiber and 10% fiberglass, and the lowest value of 27,154 MPa at 10% sugarcane fiber with no fiberglass. The maximum strain observed was 0.0050 mm/mm, and the minimum was 0.0012 mm/mm. The highest elastic modulus was 71,287 MPa, while the lowest was 5,384 MPa. These results confirm that an optimal combination of natural and synthetic fibers significantly enhances the mechanical performance of the composite. This research highlights the potential of sugarcane fiber as a sustainable reinforcement alternative in the development of environmentally friendly composite materials.
