Abstract

The previous research of using truss system reinforcement in the beam without concrete (BTR) in the tension zone causes a decrease in flexural capacity due to the failure in the area near the support. Therefore, it is necessary to add tensile reinforcement in the support zone. This study aims to analyze the ultimate capacity of the truss system concrete beam strengthened with tensile reinforcement and to analyze the effect of tensile reinforcement in support zone due to crack pattern. This study was conducted experimentally in the laboratory. The dimension of truss reinforced concrete specimens are 15 cm x 20 cm x 330 cm that added tensile reinforcement with three types of length, they are BTRP 40D, BTRP 50D, and BTRP 60D, where D (13 mm) is diameter of tensile reinforcement. The flexural test is carried out by monotonic static loading. The results showed that tensile reinforcement in BTRP 40D was not able to carry the ultimate capacity due to premature failure in the support zone. while BTRP 50D and BTRP 60D specimens can enhance the ultimate capacity without facing premature failure in the support zone. The tensile reinforcement of 60D has the highest ultimate capacity because it can carry the biggest loads and minimum crack pattern.

Abstract

This activity aimed to introduce vocational higher education and socialize the selection of new student admissions at the Tridaya Virtu Morosi Polytechnic in 2024 to high school and vocational school students in Konawe Regency, Southeast Sulawesi. The methods used were presentations, discussions, and question and answer sessions involving resource persons from the Tridaya Virtu Morosi Polytechnic and representatives from local high schools and vocational schools. The results showed an increase in prospective students' understanding of vocational education and study opportunities at the Tridaya Virtu Morosi Polytechnic. Students' interest and enthusiasm to continue their education at the vocational level and enroll at the Tridaya Virtu Morosi Polytechnic increased after participating in this activity. This activity also helped promote the study programs offered and attract potential new students from high schools and vocational schools in Konawe Regency.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh komposisi perekat terhadap karakteristik termal briket arang pelepah sagu. Tiga komposisi yang diuji adalah briket dengan perbandingan presentase arang pelepah sagu:perekat tepung kanji masing-masing 90:10%, 80:20%, dan 70:30%. Pembuatan briket dilakukan pada tekanan konstan 70 kgf/cm2. Pengujian termal dilakukan menggunakan tungku pembakaran silindris yang dirancang untuk aliran udara secara alami. Setiap komposisi diuji dengan tiga briket. Selama pembakaran, penurunan massa dan peningkatan suhu ruang bakar diamati setiap interval waktu 4 menit menggunakan timbangan digital dan termokopel tipe K. Hasil penelitian menunjukkan bahwa komposisi dengan perbandingan 90% arang pelepah sagu dan 10% perekat tepung kanji menunjukkan kenaikan suhu pembakaran tertinggi. Hasil ini menunjukkan bahwa proporsi perekat tepung kanji yang lebih rendah dalam briket dapat meningkatkan efisiensi pembakaran

Abstract

Penelitian ini bertujuan untuk menganalisis kekuatan sambungan dengan menggunakan 4 tipe lubang yang berbeda. Adapun 4 tipe lubang sambungan (bolt holes) diantara lain Standard Hole (STD) , Short-Slotted Hole(SSL), Oversized Hole(OVS), dan Long-Slotted Hole (LSL). Analisis perhitungan sambungan menggunakan metode Load and Resistance Factor Design (LRFD) .Desain tiap sambungan menggunakan jumlah baut yang sama dengan tata letak baut seragam. Adapun baut yang digunakan berdasarkan standar SNI 1729:2015.  Dari hasil analisis kuat sambungan tipe lubang standar (Standar Hole) menunjukan tahanan terkecil kekuatan block geser sebesar 731.71 kN. Lubang oversized nilai tahanan friksi sebesar 104.89 kN, Lubang short-slotted hole sejajar arah gaya sebesar 104.89 kN , kemudian yang tegak lurus arah gaya memiliki tahanan friksi sebesar 123.4 kN. Lubang slot panjang memiliki 2 tahanan friksi yaitu yang sejajar arah gaya sebesar 74.04 kN dan tegak lurus sebesar 86.38 kN.
