Abstract

The growth responds of Pleurotus comunicipae to the use of cold water-soaked teakwood sawdust as a growth medium was investigated. Teakwood sawdust was soaked in cold water during the time periods of 1, 3, 5 and 7 days) with ten replications. Unsoaked teakwood sawdust was also prepared and used as a control. Measurement variabels consisted of time required for a completely covering mycelial growth, number of fruitbody, and fungal mass (green and dry weight). Results showed that P. comunicipae placed on soaked teakwood sawdust medium had a better growth than control (without soaking) medium. The medium with increased soaking period produced a good growth ability of P.comunicipae. At teakwood sawdust soaked for 7 days, the average of mycelial growth to cover teakwood sawdust medium, number of fruiting bodies, green weight and dry weight at the first harvesting were 52.6 days, 8.6 units, 100.5 grams and 13.4 grams, respectively. Keywords: teakwoods sawdust, Pleurotus comunicipae, cold water soaking, growth ability

Abstract

A research was conducted to evaluate the quality of white refined sugar produced from palm tree (Arenga pinnata) using direct and indirect cooking processes. Visual methods were applied to determine color, shape and texture of produced sugar. The sucrose, ash, and other sugar contents as well as dry weight of produced refined sugar were also analyzed. Results showed that the production process using direct cooking resulted in small granulated, dry, compacted and milky white refined sugar, while that using indirect cooking (four hours storage) produced clay granulated, less compacted, dust shape and browning refined sugar. The sucrose, ash, and other sugar contents found in direct cooking process were 10.27%, 0.016%. and 2.68%, respectively, while those found in indirect cooking process were 11.11%, 0.018%, and 2.78%, respectively. Keywords: Palm tree, Arenga pinnata, nira, white refined sugar

Abstract

This study was aimed to determine quality of sugar palm vinegar (Arenga pinnata) based on SNI 01-4371-1996. The result was expected to provide material information about the quality of sugar palm vinegar based on SNI 01-4371-1996 and as a reference for further research. Nira of sugar palm as sample used in this research were obtained from Kappang Village, District Cenrana, Maros Regency, South Sulawesi Province. The process of making vinegar through by fermentation of the nira which has been obtained from the field. Vinegar is produced and then tested their quality based on SNI 01-4371-1996. The results showed that the variables that meet the SNI 01-4371-1996 on vinegar fermentation are the liquid form and flavour, acetic acid content, residue of alcohol, Pb and Cu metal contamination and arsenic contamination. Variables that not meet the SNI 01-4371-1996 are NaCl, the amount of dissolved solids, test of total sugar, contaminant of metals zinc (Zn) and microbial contamination. Key words: Sugar palm vinegar, Arenga pinnata, nira, SNI 01-4371-1996

Abstract

The purpose of this research to compared the characteristic and productivity of three silkworm seeds. The result of this research can be information for user of the sericulture. Three seeds examination from Perum Perhutani Soppeng ( P1), BS09 ( P2) and C103 ( P3) from Perum Perhutani Candiroto (Central Java).The observation will be done the hatchability of eggs, resistance of larval, and the characteristic of the larval. Result of research shows that stadium of P2 and P3 silkworm is shorter (21 days) than P1 (23 days). Larval characteristic; colored and larval pattern are equal relative except longer caterpillar P1 length from P2 and P3. Cocoon characteristic; colored, wrinkle and its hardness relative is of equal except size measure and form the cocoon, ellipse globular bigger P1 than P2 and P3 are elliptical like peanut. The result of this research was showed that examination three seeds hybrid of productivity observation (hatchability of eggs and resistance of mature larval,) P1 better than P2 and P3. Key words: Characteristic, productivity, hybrid seed, silkworm (Bombyx mori L).

Abstract

This research aimed to determine the role of rice husk ash as pozzolanic material in reducing water absorption of rice husk cement composite. Rice husk ash obtained by burning rice husk conventionally in kiln drum. Preparation of water absorption testing samples was conducted according to ASTM C 140, while ASTM C 90 used to evaluate the desired water absorption. Rice husk ash as of 40 % significantly reduced water absorption of the composite, but only rice husk ash of 20 % dan 30 % fulfilled the ASTM C 90 requirement. Addition of lime in the mixture increased the water absorption. Key words: pozzolamic, water absorption, rick husk, rice husk ash.

Abstract

At this time the technology required to conduct a study of land mainly related to land change and land condition analysis. To anticiapate this need for technology Remote Sensing and Geographic Information System (GIS) that can quickly and accurately to conduct a study on land resources. Critical land is a condition of land which is the result of an error in the maintenance and land management. Kolaka Utara Regency a new district which has the problem of land mainly biophysical and social condition.In this case the methode used is to land suitability analysis approach based on FAO and determination based on the rules Director General Land Rehabilitation and Social Forestry – DEPHUT, SK.167/V-SET/2004, combined with productivity data field based on their utilization. Based on the analysis with Remote Sensing and GIS in Kolaka Utara Regency result that is dominated by protected forest area of 163.376,51 ha (53,0 %), followed by limited production forest 65.887,63 ha (21 %), cultivation area 60.977,75 ha. (19,6 %) and production forest convertion 20.258,94 ha (6.5 %). Land use and land cover largest is forest area of 177.850,02 ha (57,3 %), cocoa palantation area 91.066.80 ha (29,3 %), garden mixed area18.517,76 ha (6,0 %), shrub area 11.615,40 ha (3,7 %), and clove plantation area 4.067,93 ha ( 1,3 %). Potential land critical area is 39.040,96 ha (12,6 %), land rather critical is 13.513,43 ha (4,4 %), critical land is 47.534,21 ha, (15,3 %) and land critical immensely is 19.509,42 ha (6,3 %), and land while the rest is not critical is 190.902,81 ha (61,5 %). Degraded land spread in all areas well outside the region (cultivate area) and within region (forest area). Key words: Inderaja, SIG, critical land
