Abstract

Sengon wood can be used as an alternative to solid wood, although this type of wood has low mechanical properties, as technology develops, it can be processed into engineered wood products, namely LVL. Furthermore, the problem is finding out how the connection mechanism is, considering that this greatly affects the stability of the structure when the LVL Sengon wood is applied in structural design. This research is focused on examining the parameters of LVL Sengon wood joints using bolts to predict the level of stiffness and ductility of the joints, where wood failure leads to brittle failure. Wood Testing based on ASTM 5652-95 provisions with a distance of one bolt is 5d and for a distance of two bolts is 5d (d = bolt diameter). The test results show that the value of the joint stiffness is influenced by the bolt connection binding force system which will increase the slip resistance. With the increase in the number of bolts the value of the joint stiffness will be greater, this is due to the increased bearing capacity of LVL wood due to the axial force of the bolts. The ductility value of the joint decreases as the number of bolts increases. This is due to the group action factor of the joint, the outer bolt connection will compress the wood which will affect the value of the joint slip and reduce the bending angle of the bolt.

Abstract

Bambu merupakan tanaman rakyat dengan pertumbuhan yang cepat, dimana bambu dengan kualitas baik dapat diperoleh antara umur 3,5 sampai dengan 5 tahun. Pemanfaatan bambu pada sentra kerajinan di desa Kemutug, Kecamatan Baturraden hanya memanfaatkan bahan baku bambu sebagai mebelair seperti kursi, meja, balai bengong. Material waste yang dihasilkan dari produk mebelair ini sangat tinggi dan belum dimanfaatkan dengan baik. Salah satu alternatif pemanfaatan material waste dari produk bambu adalah dengan dijadikan bambu laminasi untuk menambah nilai ergonomis. Metode yang digunakan adalah pendidikan masyarakat dan pelatihan, pendidikan masyarakat dilakukan dengan memaparkan dan menjelasan mengenai gambaran pengetahuan tentang pemanfaatan bambu, Pelatihan dilakukan dengan mempraktikkan proses pembuatan bambu laminasi. Dengan diadakannya kegiatan ini diharapkan akan meningkatkan ketertarikan sentra produksi kerajinan bambu pada bambu laminasi sehingga dapat meningkatkan diversifikasi produk untuk terciptanya ekonomi yang kreatif. Respon dan keberterimaan masyarakat terhadap teknologi bambu laminasi cukup tinggi, masyarakat menyambut baik dengan adanya perkembangan teknologi bambu laminasi.

Abstract

Residential buildings built are mostly non-structural buildings that add the greatest amount of damage. Problems that occur namely, reduced public awareness in terms of earthquake disaster management which is included in the construction of residential buildings in accordance with waterproof standards for educational education activities or providing assistance to the community about how to process and how to make houses that have earthquake resistant structures. The expected outcome is that the Brani village community is increasingly aware of the dangers posed by the earthquake and is understood to make earthquake resistant structures at home, Making knowledge for Brani villagers as material for repairs and overhauling the structure of residential buildings in order to avoid the dangers posed by earthquake. There are two methods used, namely community education and surveys. Community education through material, and discussion about science and technology materials. Lectures are used to provide knowledge about earthquake hazards and how to create earthquake-friendly residential structures. Evaluation and validation are done by questions and answers and discussion of respondents' answers. The number of respondents who participated in this activity amounted to 32 people from various backgrounds, Brani villagers have a high awareness of the quality of residential buildings, as evidenced by the results of a positive response to the construction of housing in accordance with the regulations. Although the cost of building earthquake-friendly houses is 30% greater than ordinary houses, the community is enthusiastic and accepts the adoption of earthquake-friendly simple residential technology.

Abstract

Background: Building Information Modeling (BIM) is a technology in the field of Architecture, Engineering and Construction that is capable of simulating all information in a development project into a three-dimensional (3D) model. One of the government's efforts in dealing with the Industrial Revolution 4.0 is implementing the use of BIM, and construction technology innovations in each project cycle. By applying the BIM method, both managers, consultants and contractors are able to save processing time, costs incurred and the required workforce. The application of BIM technology can minimize the impact of work delays, increased costs, and construction failures. Contribution: The results of the analysis of the needs of partners show that not all construction service businesses, especially in Banyumas, know and implement BIM. This community service activity is intended to provide basic training to construction service businesses regarding the operation of BIM using Tekla Structures. Method: The method used is a partner needs analysis survey, lectures, demonstrations, discussions, and mentoring. Results: The results of this dedication show that as many as 81% of participants understand the BIM concept after participating in this activity. Conclusion: The holding of this training will provide an overview, improve skills for construction services in Banyumas. Furthermore, it can be applied to the construction process (planning, implementation and maintenance), so that it will produce competitive construction service design products

Abstract

Kayu kualitas tinggi dengan ukuran besar dewasa ini sudah sangat jarang ditemui. Salah satu cara meningkatkan kualitas kayu dengan cara teknik laminasi dan atau dikompositkan dengan bambu. Selain itu, keterbatasan ukuran kayu dan bambu maka diperlukan teknik penyambungan. Sambungan pada kayu memegang peranan sangat penting karena untuk memperoleh dimensi yang dibutuhkan. Alat sambung pada kayu umumnya yaitu baut atau pasak (dowel). Kekuatan sambungan dowel dapat ditentukan dengan teori Europen Yield Model (EYM), yaitu untuk menentukan kekuatan tahanan lateral (Z) akibat gaya aksial berdasarkan mutu dowel, bahan yang disambung dan bentuk geometri sambungan. Tujuan penelitian ini untuk mengetahui kekuatan tahanan lateral alat sambung baut pada komposit bambu-kayu. Benda uji dibuat dengan ukuran 50 x 50 x 150 mm dengan alat sambung baut diameter 5 mm, 10 mm, dan 15 mm dengan persentase bambu adalah 50%. Pengujian tahanan lateral dengan memberikan beban tekan statik pada benda uji sampai runtuh dengan alat Universal Testing Machine (UTM). Hasil eksperimental menunjukkan nilai tahanan lateral sambungan baut 5 mm, 10 mm, dan 15 mm berturut-turut yaitu 12,71 kN; 20,17 kN; dan 25,75 kN. Persentase peningkatan adalah sebesar 58,74 % (diameter 10 mm) dan 102,68 % (diameter 15 mm) terhadap baut diameter 5 mm yang dipengaruhi nilai kuat tumpu kayu-bambu dan kuat leleh baut.
