Particle boards are the solution to the productivity problems of the timber industry which deficiency of raw materials. The manufacture of particle boards from Areca nut shell and Mahang wood powder is an effort to develop existing types of particle boards as well as efforts to utilize areca nut waste and increase the economic value of local wood (Mahang wood). The aim of this study was to determine the effect of quantity variations of adhesive to the composition of the mixture. There are four types of particle board variations are made with the same composition of areca nut and powder but different quantity of adhesive. The determination of physical properties and mechanical properties of particle boards based on JIS A 5908 2003 or SNI 03-2105-2006. The result was an increase in physical and mechanical properties on the particle board whose content of adhesive was greater. The other sides, the mechanical properties of all variations of particle board do not fulfill the existing standards.Keywords: Areca nut particle board, Mahang wood powder particle board, adhesive content

In general, the bridge type is a reinforced concrete bridge, composite and steel frame. The Baki River Bridge was originally a 40 m long Wood type bridge connecting the village of Mengkopot - Tanjung Pisang because the condition of the Baki river bridge has been damaged especially on bridge floors and girders due to age, so it is planned to re-use the steel frame bridge structure. By using the steel bridge structure, it is expected that later it can be a comparison for the future bridge planning.In this study, the structure of the planned bridge consists of bridge slabs, sidewalk slabs, backrest pipes, longitudinal and transverse girders, steel frames, wind ties, and joints. By following the SNI T-02-2005 bridge loading standard, SNI T-03-2005 for planning steel bridge structures and SNI T-12-2004 for planning concrete structures on bridges.From the planning results obtained thickness 200 mm Bridge Slab and thick sidewalk slab 250 mm with a longitudinal girder profile used WF 600.200.11.17 mm steel with a distance between girders 1.75 m. Transverse girders of steel profiles WF 700,300.13.24 are used with the distance between girders 5 m. Used Steel profiles WF 400,400.13.21 as Main Frame and Steel WF profile 150.150.7.10 as profiles for wind ties.‘Keywords: Steel frame, girder, connection,

The use of light wood combined with heavy wood can improve the quality of the combinationwood. Apart from being used as laminated beams, a combination of light wood and heavy wood can also be used as a laminated column given compressive loads. Based on SNI 7973-2013, the adhesive that was permitted on built up columns or laminated columns can be in the form of bolts and nails, so this study has also used adhesive nails and bolts. This study purpose to determine the compressive capacity of the laminated column which combines several types of wood. The specimens made were four variations of the laminate column. Furthermore, three layers of wood have been used on one laminated column with heavy wood types on the outermost layer. The results showed that all variations of the laminated column had a higher compressive capacity than the solid column. Keywords: compressive capacity, lamination column, light and heavy wood

Jembatan adalah bagian dari sistem transportasi nasional yang mempunyai peranan penting. Di Desa Putri Sembilan Kecamatan Rupat Utaraterdapat satu jembatan yang sangat penting dimana jembatan ini merupakan satu-satunya alternatif warga Desa Putri Sembilan menuju pelabuhannelayan dan perkebunan. Kondisi jembatan pada saat ini sudah rusak dengan material kayu yang sudah lapuk dan berlubang. Untuk itudirencanakanlah jembatan baru dengan menggunakan struktur beton bertulang. Perencanaan ini mengacu pada SNI 1725-2016 tentang pembebananjembatan dan SNI T-12-2004 tentang perencanaan struktur beton untuk jembatan dengan harapan untuk mendapatkan struktur jembatan yang amandan sesuai dengan standar yang berlaku. Desain terdiri atas slab jembatan, trotoar, plat injak, balok girder dan balok diafragma.Setelah dilakukan perencanaan diperoleh tulangan pokok slab D16-200 mm dan tulangan bagi D13-300 mm. Tulangan arah memanjang platinjak diperoleh tulangan D16-200 mm sedangkan untuk yang melintang diperoleh tulangan D16-250 mm. Untuk tulangan utama balok girderdiperoleh tulangan 28D32 mm, tulangan tekan digunakan tulangan 8D32 mm dan tulangan geser digunakan tulangan Ø13-100 mm. Sedangkantulangan utama balok diafragma menggunakan 3D16 mm dan tulangan geser diperoleh tulangan Ø13-200 mm.

Beton yang ditambahkan Polinex HE memiliki nilai slump yang dua kali lebih besar dari beton tanpa Polinex HE. Hal ini dapat menyebabkan terjadinya segregasi pada saat pengecoran, Untuk itu coba dilakukan penelitian dengan mengurangi jumlah air pada beton yang menggunakan Polinex HE. Tujuan penelitian ini adalah untuk menyelidiki bagaimana pengaruh pengurangan air terhadap nilai slump, berat isi beton dan mutu beton. Sebanyak 72 sampel silinder beton diameter 10cm dan tinggi 20 cm dibuat untuk beton K-250 dan beton K-350. Variasi pengurangan air mulai dari 5-20% dari berat air, dengan menggunakan Polinex HE sebanyak 1% dari berat semen. Pengujian yang dilakukan adalah pengujian slump, berat isi beton dan kuat tekan beton pada umur 3 hari dan 28 hari. Hasilnya, diperoleh nilai slump yang masih lebih besar dibandingkan dengan nilai slump beton tanpa Polinex HE. Terjadi pengurangan berat isi beton seiring dengan pengurangan jumlah air pada beton. Untuk beton K-250 kuat tekan beton maksimal terjadi pada variasi pengurangan air 5% dan untuk beton K-350 kuat tekan beton maksimal terjadi pada variasi pengurangan air 20%.

The decrease in a slump due to the long distance between the batching plant and the casting site is a common issue. This also increases the likelihood of reducing concrete quality due to delays in compaction. To reduce the risks of slump loss and decrease concrete compressive strength, a combination of two admixtures was employed: Sika Plastocrete RT6 Plus, acting as a retarder, and Grolen Hp19R, serving as a superplasticizer. The dosages applied were 0.3% for Sika Plastocrete RT6 Plus and 0.4% for Grolen Hp19R. Compaction delays were tested at 0, 60, 90, and 120-minute intervals. The results demonstrated that combining these two admixtures could enhance the concrete's setting time, slump, and compressive strength compared to normal concrete. However, with the increasing delay in compaction time, there was a noted decrease in the concrete's slump and compressive strength.
