Abstract

The availability of water is a very important factor in the germination process. Therefore, it is necessary immersion process mahogany seeds to accelerate germination. The purpose of this study was to determine the effect of immersion time and media of sow to germination mahogany (Swietenia mahagoni (L) Jacq). This research was conducted from December 2015 to February 2016 at Permanent Nursery of BPDAS Palu – Poso, Tadulako University. This research applied a completely randomized design, factorial pattern with 9 treatments and 5 replications. The treatments of this research were immersion time that consist of 24 hours, 49 hours and 72 hours. Data were analyzed by analysis of variance and tested using Significant Difference test (LSD) with level 5%. The results of this study showed that immersion duration and media sow has significant effect on germination percentage, rate germination, root length and vigor, except the treatment of sow media has no significant effect on root length of mahogany seedling, and did not interaction between the two treatments. The highest germination percentages in treatment of immersion were 25 hours (P1) and 48 hours (P2) namely 56,87%, and 45,77%, respectively, and the lowest was 72 hours (P3) namely 24,43%. The fastest rates of germination for immersion treatment were 72 hours (P3) and 24 hours (P1) namely 17,73 days, 21,01 days respectively, and the latest was 48 hours (P2) namely 21,89 days. the longest roots were in the immersion treatments for 24 hours (P1), and 48 hours (P2) namely 9,26 cm, 8,63 cm respectively, and the shortest was in 72 hours (P3) namely 7,71 cm. The highest seed vigor was in the immersion treatment for 24 hours (P1) and 48 hours (P2) namely 50,23%, 39,11%, respectively, and the lowest was 72 hours (P3) namely 22,66%. The optimum of sow media for all parameters was sail + goat manure + carbonated rice husk.

Abstract

Birds are the fauna with extensive range of habibat, from lowlands to highlands, as well as various types of ecosystems, from natural to artificial ecosystems. In addition to their significant role in the the ecosystem balance, birds serve as an indicator of environmental changes. The aim of this study was to determine the level of the bird presence, species composition, and species diversity in the forest located at Lonca Villages, Kulawi District, Sigi Regency, Central Sulawesi Province. Line transects method was employed in the field study where the observers walk along the direction and center-line of the transect steadily and record occurences of the entire birds. Observations were performed at 06:00-09:00 a.m. (Central Indonesian Time/Wita) and 03:30-06:00 p.m. (Central Indonesian Time/Wita). Observations were replicated 4 (four) times. Based on the results of measurement, there were 27 species of birds representing 16 families with a number of individuals of 142 birds in two different habitat types. More results showed the species composition in the study area. Index of species diversity in open habitat was H’=2,8881 and in closed habitat was H’=2,8070, t-test result of species diversity index between those habitat types was similar. Sulawesi hornbill (Rhyticeros cassidix), Black-crowned White-eye (Zosterops atrifrons), and Hair-crested Drongo (Dicrurus hottentottus) dominate the two habitat types.

Abstract

Non timber forest products are potential assets to generate foreign exchange. One type of plants that has a trade prospect is rattan. The method used belt transects. The size of the plots is 10 m x 100 m along 1000 m. The result showed that there were three types of rattan, namely Batang Rattan (Calamus zollingeri Becc), Ronti Rattan (Calamus axillaris Becc) and Tohiti Rattan (Calamus inops Becc, ex. Heyne). The density was based on the length of the rattan stems: the length <3 m (133 stems/ha), between 3-5 m (58 stems/ha) and> 5 m (146 stems/ha). The highest potential of rattan at all regeneration levels is dominated by Batang rattan (Calamus zollingeri Becc) of seedling level 93.13%, and 122 stems/ha, 87.93% and 51 stems/ha and adult 68.49% and 100 stems/ha. The type of rattan at all levels of natural regeneration was dominated by Batang rattan (Calamus zollingeri Becc) with Import Value Index (INP) of 184.04%, weaning rate of 178.84%, and adult rate of 151.82%. In the type of Ronti Rattan (Calamus axillaris Becc), the seedling level had an Important Value Index (INP) of 15.96%, weaning rate of 21.16% and an adult rate of 39.16%. While the rattan species that had the lowest Importance Index Score (INP) was the lowest in all natural regeneration classes. That was Ronti Rattan (Calamus inops Becc ex Heyne) with Important Value Index (INP) of seedling and weaning rates absent and at adult level with Important Value Index (INP) of 9.02%.

Abstract

The current high population rate leads to inevitable, greater demand for energy. In fact, most urban communities depend on oil and gas as the energy source for daily usage while the communities in rural and  remote  areas  preferably  use  woods  as  fuel.  The  search  for  alternative  source  to  reduce  thedependency on the availability of fuelwood has been done by utilizing agricultural waste, industrial waste and  domestic  waste,  including  coconut  shells  and  sawdust.  These  wastes  can  be  processed  into briquettes as potential solid fuel. The present study aims to investigate the quality of briquettes made from a mixture of coconut shells and palapi sawdust. It was done in May to July 2016 at the Mechanical Engineering Labolatory, Tadulako University. A completely randomized design (CRD) was employed, withthree treatments: A (100% coconut shell charcoal), B (85% sawdust + 15% coconut shell charcoal) and C (85% coconut shell charcoal + 15% sawdust). The parameters included density, moisture, volatile matter, ash, and fixed carbon. The results showed the average moisture, ash, fixed carbon, volatile mater, and density of charcoal briquettes were: 4.62–4.99%, 4.51–5.55%, 29.63–53.17%, 36.94–59.88% and 0.48–0.7g/cm3, respectively. It indicates that the mixture of coconut shell and sawdust has a very significanteffect on ash content, volatile matter, fixed carbon and density, but insignificant effect on water content.

Abstract

Palu City is the Capital of Central Sulawesi Province, which is also the center of a variety of activities and services for both residents within the city and other areas outside or around the City. Activities and services of the population have resulted in the city of Palu experiencing very rapid development. The rapid growth of settlements and development in the city of Palu will have a significant influence on land use change. Changes in land use that are not in accordance with the rules of spatial planning can result in decreased environmental quality, environmental degradation / environmental damage and reduced natural resources. The declining quality of the environment is due to the increasingly spatial allocation of space for urban vegetation. The purpose of this study was to determine the level of air temperature distribution in Ulujadi District based on Landsat 8 imagery and determine the level of vegetation density based on air temperature. This research was conducted for 3 months from February to May 2016. Analysis of air temperature using band 11 to analyze the distribution of air temperature by comparing the vegetation density analysis of NDVI (Nomalized Difference Vegetation Index) using band 5 (NIR) and band 4 ( Red) on Landsat 8 imagery to determine the effect of vegetation absorption on air temperature by using ArcGIS software version 10.2. Based on the analysis of air temperature using Landsat 8 imagery, it can be concluded that the distribution of air temperatures in Ulujadi District ranged from 18.89 - 25.890C with an area of 1954.48 Ha (31%), 25.90 - 32.890C with an area of 2.198 , 67 Ha (35%), and the highest temperature distribution in Ulujadi District reached 2,213.83 Ha (35%) with an air temperature level of 32.90 - 39.890C. The level of vegetation density in Ulujadi Subdistrict is divided into three with a vegetation index value of -0.19 - 0.25 sparse density, with a distribution area of 1,381.79 Ha (22%), moderate density 0.25 - 0.35 medium density with the distribution area is 965.57 Ha (15%), the density of the meeting is 0.35 - 0.60 with a distribution area of 4.018.80 Ha (63%) from the area of Ulujadi Subdistrict

Abstract

Vegetation cover is closely related to temperature that causes the variation of temperature magnitude with a fairly high intensity. Meanwhile, surface temperature is affected by vegetation. This study aims to determine the type and the extent of vegetation distribution based on temperature zones using Landsat 8 imagery. It was carried out in the protected forest of South Dolo Sub-district, Sigi Regency, Central Sulawesi, Indonesia. The methodology includes unsupervised classification method and survey method. Data collection phase employs the techniques to obtain primary and secondary data, and data processing. The results indicate the relationship between vegetation cover and the changes in surface temperature, and the effect of the vegetation cover on the surface temperature of the protected forest in South Dolo Sub-district. The Landsat 8 image classification shows this area is dominated by tree with temperature of 17.3–22.2 ˚C, while the temperature of shrubs /open land is 22.3–31.7 ˚C. The relationship between temperature and vegetation cover is reflected from the value of y = 25.687 – 10.043x in trees and y = 2.980 + 3.000x in shrubs/open land with a coefficient of determination/R2 = 1, which indicates the extent of the area of vegetation cover (y) is affected by surface temperature (x).
