Abstract

This research aims to determine the effect of double shear connection strength of six types of timber in various displacement based on diameter and the number of bolts. Six types of wood used are bangkirai, punak, meranti, sengon, bintangur and kapur. Double shear connection consists of the main member (wood) and side member (steel plate) with bolts connected. The average moisture content of sengon, meranti, bintangur and bangkirai are relatively similar (about 12 %), while kapur and punak are slightly higher at around 14 %. In contrast, the average density of six wood species are greatly vary ranging from the lowest sengon 0.26 g cm-3, to the highest 0.82 g cm-3 of bangkirai wood. The total load and load per bolt on double shear connection using bolts connector are influenced by the type of wood, diameter and number of bolts. There is a strong tendency that the higher specific gravity or density of the wood makes higher total load and load per bolt on double shear connection for each displacement. In addition, an increasing number of bolts makes the total load increased. On the other hand, it decreases load per bolts for each of bolts diameter. The use of 10 pieces of 7.9 mm diameter bolts on double shear connection for almost all type of wood produces the highest average total load compared to the other bolt diameter for both displacement 1.5 mm and 5 mm. In the same connection displacement the highest load per bolt is still obtained from using 7.9 mm bolt diameter but with the use of 4 pieces of bolts for almost all types of wood with the exception for punak and bitangur showing the highest values are obtained from 6 pieces of bolts. Bangkirai wood, kapur, punak, bintangur and meranti can be used as the main member in double shear connection by using bolt with diameter 6.4 mm, 7.9 mm and 9.5 mm because of fulfilling the requirements of PKKI (1961). Key words: Bolts, double shear connections, displacement, total load, load per bolt

Abstract

Biological activity of termites consistently generates various biogenic products depend of the type of food sources. Furthermore, the biogenic product is believed to have an important role in the improvement of soil physical and chemical properties. The purpose of this study is to determine the structure and chemical properties of biogenic products resulted from the activity of termites Schedorhinotermes spp. using newsprint paper and tofu processing wastes as food sources. Newsprint paper waste was mixed with tofu processing wastes water at a different levels, i.e. 10 %, 20 %, and 30 % (w/v) for the objective of study. Each of the mixture with weight of 18,8 g equivalent to oven dry weight was then placed in the sample container unit size 6 x 6 cm, placed at about 3 cm underground with the indicated of termite Schedorhinotermes spp activity, and covered by PVC stopper. The testing unit were left in place for about 6 weeks to allow the termite attacks. The attacked sample unit were then analyzed for their structure and chemical properties including bulk density, aggregate fraction distribution, pH, C-organic content. The soil around the sample unit were took using a 7 cm diameter ground ring to be used as a reference or comparison with biogenic structures formed by termites. The result showed that the biogenic products have better structure and chemical compared to the its surrounding soil.

Abstract

Apart from being a key to identifying wood, the characteristics of the anatomical structure of cell walls can be used as a reference in determining the quality of wood, especially for its use. However, the characteristics of wood in the same species are sometimes found to be different due to the growing place is unidentical. Therefore, this study aimed to identify the cell wall characteristics of Jabon Merah wood from Wajo provenance. The wood was collected from Tangkoro Village, Pitumpanua District, Wajo Regency, South Sulawesi. It was then prepared in slicing and maceration samples. The structures of cell walls observed in the preparations were a pit, perforation plate, and tylosis. The results showed the Jabon Merah had inter vessel pit and perforation plate types, namely polygonal alternating and scalariform, respectively. Also, it had a tylosis in the vessel.

Abstract

Non-timber forest products (NTFPs) has a significant role both from the economic aspect as well as the ecological and socio-cultural aspects. Aren (Arrenga pinnata Merr) is one of NTFPs that has high economic value so that it is managed and cultivated by the community, especially for those who live around the forest. However, the management of the palm sugar business is still simple and limited to household businesses for the fulfillment of daily life. This study aims to calculate the income earned by sugar palm processing farmers, especially in one village in Sinjai Regency, South Sulawesi. The data collection method was carried out through direct observation and interviews with 30 respondents for sugar block products and 5 respondents for palm sugar. The data analysis using net income including analysis of total costs and analysis of total revenues on sugar block and palm sugar. The results showed that this palm sugar business contributed to the income of the community, especially palm sugar processing farmers with an average income of Rp.10,864,500 per year for sugar block and Rp.7,555,200 for palm sugar. Palm farmers in Gantarang Village who produce sugar block have a higher income than those producing palm sugar because farmers generally produce sugar block. This is partly due to the amount of production produced, costs incurred, revenues and skills possessed by palm sugar processors.

Abstract

Rajumas merupakan tanaman lokal yang menjadi komoditi endemik di Nusa Tenggara Barat yang jarang dimanfaatkan (lesser-used wood species) karena kekuatan dan keawetannya rendah Kualitas kayu rajumas dapat ditingkatkat dengan mengaplikasikan bahan pengawet maupun bahan pelapis pada kayu tersebut. Faktor utama yang mempengaruhi keberhasilan aplikasi bahan pengawet maupun bahan pelapis pada kayu adalah keterbasahan kayu itu sendiri. Penelitian ini dilakukan untuk menguji keterbasahan kayu rajumas pada masing-masing 3 papan radial dan 3 papan tangensial kayu rajumas. Masing-masing contoh uji diuji keterbasahannya pada 5 titik yang berbeda dengan metode sessile drop. Hasil pengukuran menunjukkan bahwa penampang tangensial memiliki keterbasahan yang lebih tinggi dibandingkan dengan penampang radial. Rerata K-value yang dihasilkan pada penampang radial masing-masing adalah 0.15, 0.15 dan 0.16 sedangkan rerata K-value yang dihasilkan pada penampang tangensial masing-masing adalah 0.36, 0.32 dan 0.30. Meski demikian hasil tersebut mengindikasikan bahwa tidak ada perbedaan yang signifikan antar pola penampang kayu pada kayu rajumas. Rerata K-value dari semua kayu yang diuji lebih besar dari 0 yang mengindikasikan bahwa cairan dapat menyebar dan menembus permukaan kayu yang diuji.
