PEMANFAATAN SUMBERDAYA HUTAN DI HUTAN LINDUNG KECAMATAN ALU KABUPATEN POLMAN PROPINSI SULAWESI BARAT
Get PDFThis study aims to determine the activity of the utilization of forest resources and to know local community wisdom related to protection forest in the Alu Village areas. This research was conducted by using Rapid Rural Appraisal (RRA) method. Respondents in this study were communities living in and around the protection forest area and conducting activities in the forms of utilizing the forest resources. The observed variables were the forms of community activities in the protection forest and local community wisdom in using the forest resources. The results show that activities of villagers consist of: 1) the use of timber for home construction or repair and for fuel wood, 2) the utilization of rattan, 3) the utilization of bamboo, 4) the utilization of palm, 5) the utilization of honey bee and other forest products. In addition, local community wisdom in the utilization of forest products was found to be in the form of prevailing institutions in the village of Alu. The forms of institutions are forest harvesting institutions, forest land use institutions, and forest protection and security institutions. In general, Alu Villagers have the awareness to preserve the environment, ecological balance and sustainability of the population to be bequeathed to their generation. Yet, the wisdom is prone to turn down particularly in the institution of timber utilization.

SELEKSI PRIMER UNTUK ANALISIS KERAGAMAN GENETIK JENIS BITTI (Vitex coffassus)
Get PDFThe successful of genomic DNA amplification using RAPD technique was determined by the sequence of primer’s base and primer compound in each reaction. The aim of research was finding the best primer for genetic diversity analyses of Bitti (Vitex coffassus). The results of amplification showed that number of band between one to five bands (110-600 bp). The primer of OPK-10, OPA-17, OPQ-07 and OPP-08 can be used for genetic diversity analyses of Bitti. The best primer used for genetic diversity analyses of Bitti was OPP-08 because it had the highest number of bands (5 bands).

PENGARUH DOSIS INOKULAN ALAMI (EKTOMIKORIZA) TERHADAP PERTUMBUHAN SEMAI TENGKAWANG (Shorea pinanga)
Get PDFThis research aimed to know the effect of some doses of natural inoculants on the growth of Shorea pinanga seedling. The research was carried out with several steps including seed provision, inoculation of ectomycorrhyza, planting and maintenance in the nursery. The result of the research showed that height and number of branches were different at the significant level of 5 %, while diameter and number of leaves were not significantly different. The natural inoculants dose of 15 g showed the best growth in response to the increment of height, diameter, and number of leaves, while that of 20 g showed the best in the number of branches increment.

SIFAT FISIK DAN MEKANIS PAPAN SEMEN BERBAHAN BAKU BAMBU
Get PDFFire resistance, termite resistance, and high dimensional stability are among critical attributes of cement board composite as alternative material to replace solid wood products. This study aimed to evaluate characteristics of cement boards made from various age classes of bamboo (1-2 year old, 3-4 year old, and 5-6 year old) and nature of bamboo stem (used and fresh bamboo). Cement board was produced with target density of 0.9 g cm-3, and 30 cm x 30 cm x 1 cm in dimension and the results showed that cement board made from younger bamboo (1-2 year old) had better physical and mechanical characteristics than cement board made from the older bamboo. Most of physical and mechanical characteristics, except for modulus of rupture and dimensional stability, of cement board made from younger bamboo fulfill the Japanese Industrial Standard (JIS) A 5417-2003. The results also showed that cement board made from used bamboo had similar characteristics with cement board made from fresh bamboo.

PERANAN ABU SEKAM PADI UNTUK MENGURANGI POROSITAS CONBLOCK RINGAN SEKAM PADI
Get PDFThis research aimed to determine the role of rice husk ash as pozzolanic material in reducing porosity of lightweight rice husk-conblock. Rice husk ash was obtained by burning rice husk conventionally in kiln drum and subsequently followed by burning in furnace of 1400 Barnsted Thermolyne Type at temperature 600 oC for 2 hours. Sample test preparation and procedure of porosity was adopted from ASTM C 140. Rice husk ash significantly reduced the porosity at all treatment combinations of rice husk ash percentage, but the lower porosity (31 %) obtained by using rice husk ash of 20 %.

PENGARUH KOMPOSISI FACE-CORE TERHADAP SIFAT FISIK DAN MEKANIS ORIENTED STRAND BOARD DARI BAMBU DAN ECENG GONDOK
Get PDFThe effect of particle composition made of bamboo and water hyacinth on the dimensional stability and mechanical properties of resulted oriented strand boards (OSB) were investigated. Three layered boards were made from bamboo and water hyacinth in which bamboo strand was used as face/back layer and water hyacinth strand was used as core layer. The boards were manufactured using three levels of bamboo and water hyacinth compositions (50:50, 60:40 and 70:30) with 6 % isocyanate based on the strand oven dry weight. The results showed that dimensional stability of the OSB decreased with the increase of composition of water hyacinth strand on core layer. A higher composition of bamboo strand as face/back layer compared to water hyacinth strand resulted in increased modulus of elasticity and internal bond strength, but decreased the modulus of rupture. The bamboo and water hyacinth composition of 70:30 compositions showed better properties than other compositions.

ANALISIS KEKUATAN SAMBUNGAN GESER GANDA ENAM JENIS KAYU PADA BERBAGAI SESARAN MENURUT DIAMETER DAN JUMLAH BAUT
Get PDFThis 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).
