Abstract

Environmental degradation as indicated by the depletion of resources and the destruction of natural habitats is the impact of human-nature relationship. Furthermore, forest fires, illegal logging, gold mining and other related activities are forms of forest destruction that can be claimed to be more intense lately. Therefore, an initial measure should be carried out including identifying stakeholders’ responses toward the issues and assessment on the level of destruction. This study aims to examine stakeholders’ responses toward forest destruction in Tirtanagaya Village, Bolano Lambunu Sub-district, Parigi Moutong Regency. The techniques of data collection were observation and in-depth interview. Several key informants were selected for the interview in order to investigate their responses toward forest destruction in the study site. It used qualitative descriptive method for data analysis. In overall, the finding indicates that the responses of stakeholders in relation with forest destruction issues are relatively poor. It is evidenced by their low participation and lack of real actions to promote forest preservation. It will have a detrimental impact on the joint effort for overcoming the problems of forest destruction in Tirtanagaya Village.

Abstract

Forest is the habitat of a wide range of plant species in which these species have different sizes and ages of seedling at transplanting. In order to increase the species richness through natural regeneration, it is important to carry out research related to this topic. In the present study, the seedlings of Malapoga (Toona ciliata M. Roem) from its natural population are investigated. It primarily aims to determine the effect of storage time of the seedlings of Malapoga (Toona ciliata M. Roem) to obtain optimal seedling growth. It was conducted in June – August 2016, at the nursery of BPDAS PALU-POSO, Universitas Tadulako, Palu, Central Sulawesi. The research uses a completely randomized design (CRD) in which there are four treatments, namely: M0 = Control, M1 = 1-day storage, M2 = 2-days storage, M3 = 3-days storage. Of the four treatments, five replications were conducted hence there were a total to 20 samples. The parameters were height, stem diameter and number of leaves. The honestly significant difference (HSD) test was carried out since the analysis of variance showed a significant difference among the treatments. The results indicate that the 3-days of storage (M3) has a significant positive effect on the seedling growth, with an average plant height of 6.94 cm, stem diameter of 0.3 mm, and eight leaves are visible. It contrasts to the control in which it experiences slow growth.

Abstract

This study aims to determine the area-level greenness of mangrove ecosystems in Balinggi Sub-district, Parigi Moutong Regency, Central Sulawesi, by using Landsat 8 image data. It is expected to provide information about the normalized difference Vegetation Index (NDVI) of each site that has been analyzed using GIS. The observation was conducted in June –August 2017. The research method used in this study was by assessing the mangrove density or the level of greenness using the vegetation index method through the NDVI formula, which is effective as an initial division of vegetation areas. The NDVI can be an indicator to measure green leaf biomass and leaf area index for the classification of vegetation. Based on the results of Landsat 8 image data of 2016, the total area of mangrove forest vegetation in Balinggi was 163.30 ha and can be classified into three classes of vegetation density, namely: low (26.46 ha), moderate (55.54 ha) and high (80.08 ha). Furthermore, based on the table of Landsat image classification, the low density class has “very good” land use accuracy with a value of 100% while the high and moderate density classes have “good” land use accuracy of 75% and 67%, respectively.

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).

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 the dependency 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, with three 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 significant effect on ash content, volatile matter, fixed carbon and density, but insignificant effect on water content.

Abstract

Buranga Village is one of the villages that has extensive mangrove forests, but has been damaged over time. Therefore, it is necessary to conduct research on the Causes of Mangrove Forest Damage in Buranga Village, Ampibabo District, Parigi Moutong Regency. This study aims to determine the factors that cause damage to mangrove forests. The study was conducted in March - May 2017. This study used the Snowball sampling method in which the sample determination technique was initially small in number, then enlarged. Like a snowball that rolled a long time to become big. Samples taken amounted to 20 respondents. Observation parameters are water pollution (pa), abrasion (a), environmental stress, main livelihood, location of business land, utilization of firewood and perception of mangrove forest. The results showed that the damage to mangrove forests that occurred was more dominant due to the socio-economic factors of the local community compared to physical environmental factors can be seen from the total score that was done. In the socioeconomic factor of the community the Total Scoring Score is 230 and the Total Scoring Score on the physical environment factor was 100.

Abstract

As the largest island in Wallacea, Sulawesi is rich in biodiversity, of which most of flora and fauna are endemic. One of them is orchids. This study aims to investigate the species diversity, namely the number of the species and abundance of each species, as well as the species evenness of natural orchids in forest areas in Lembantongoa Village, Sigi district. This study was conducted for three months: February – April 2017. It was designed as an exploratory research with purposive sampling and systematic sampling as methods of sampling. The species diversity and species evenness of natural orchids were analyzed using species diversity index (H') and species evenness index (E). The findings of this study show that there are currently 15 genera and 30 species living naturally in the forest of Lembantongoa village, in which 25 species are epiphytic while 5 species are terrestrial. The diversity index is categorized as moderate, the species evenness index is relatively high and the species are evenly dispersed.
