Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar IPA dengan mengoptimalkan pemanfaatan lingkungan alam sekitar sebagai sumber belajar siswa Kelas IV MIN Parigi Kecamatan Sausu . Jenis penelitian ini adalah penelitian tindakan  kelas yang dilaksanakan dalam 2 siklus. Tahapan dalam penelitian ini meliputi: perencanaan, pelaksanaan tindakan, observasi dan refleksi. Data yang diperoleh dalam penelitian ini meliputi hasil belajar siswa, hasil observasi aktivitas guru dan siswa diambil dari lembar observasi kegiatan guru dan lembar observasi aktivitas siswa. Hasil penelitian menunjukkan pada siklus I tuntas secara individu berjumlah 18 orang dari 29 siswa sehingga diperoleh ketuntasan klasikal 62,06% dan daya serap klasikal sebesar 64,48%. Pada siklus II diperoleh ketuntasan klasikal 100% dan daya serap klasikal 84,64%. Hal ini menunjukkan bahwa pembelajaran pada siklus II telah memenuhi indikator keberhasilan dengan daya serap klasikal minimal 70 dan ketuntasan belajar klasikal minimal 80%. Berdasarkan daya serap klasikal dan ketuntasan belajar klasikal pada kegiatan pembelajaran siklus II terjadi peningkatan dari siklus I ke siklus II sebesar 37,94%, maka dapat disimpulkan bahwa dengan memanfaatkan lingkungan alam sekitar sebagai sumber belajar dapat meningkatkan hasil belajar IPA pada siswa kelas IV di MIN Parigi Kecamatan Sausu .

Abstract

Mangrove is an ecosystem with uniqe function in the life environment. Because of the influence of sea and land, there was complex interaction happened between physical and biological properties in the mangrove area. The physical properties of mangrove able to act as breakwater as well as an intrusion detterent and sea abrasion.  Litter decomposition process of mangrove that occurs can support the life of living things in it. The existence of Mangrove forest that is located in Dolago village of South Parigi sub-district at Parigi Moutong district which alleged to have suffered damage, therefore it is necessary to do research related with the damage of mangrove forest in that village. This study aims to find out the condition of the damage of forest mangrove and the physical-chemical condition of water. This study have been conducted in Dolago village, South Parigi Sub-District, Parigi Moutong District in March until May 2016. The water analysis was conducted in Natural Resources and Environmental Analysis Laboratory of Agriculture Faculty Tadulako University. This study used Line Transect and Trasect Line Plot. Data obtained from 3 paths that have been made. Water sampling conducted on each path of vegetation observation. The result showed that the mangrove forest in Dolago village has been damaged with classified as moderately damage by the density 1233 btg/ha. The influence of physical-chemical of water condition at study site is still relatively good and has not been contaminated to support the growth of mangrove. However, the relative salinity value in a state exceeds of the standards set. Keywords: Damage, Forest, Mangrove

Abstract

The objective of the research was to find out soil physical condition of Mangrove Forest in  Dolago village South Parigi Subdistrict Parigi Moutong District. The research was conducted on January to March 2016 that located in Dolago village, South Parigi Subdistrict, Parigi Moutong District. The method of taking sample was purposive sampling, soil sample taken from each mangrove stand, the dominant ones were Sonneratia alba, Rhizophora sp and shifting between Sonneratia alba, and Rhizophora sp . The soil sample was analyzed in Agronomy Laboratory of Forestry Faculty of Tadulako University, and the measurement of mud depth was done in the location directly. The result of soil sample analysis from laboratory showed that soil pH on Sonneratia alba stand was 6,20, Rhizophora sp was 6,03 and shifting was 6, 10, The soil color on Sonneratia alba stand was dark grey, Rhizophora sp was dark grey and shifting between Sonneratia alba, and Rhizophora sp was very dark grey, the soil texture of the three samples under taken stands was dominated by clay sand, water salinity on Sonneratia alba stand was 2,9 ppt, Rhizophora sp 3,0 ppt, and shifting  between Sonneratia alba, and Rhizophora sp was 2,8 ppt, and mud depth that directly measured on location showed that from the tree stands reached 78 cm height.Keywords: Physical condition, Soil, and Magrove Forest.

Abstract

Mangrove forest is one of unique forest ecosystem form which brings land and sea territory. Mangrove forest has specific characters in tidal areas, coastal marine zone and Small Islands in Bolobungkang village, Luwuk-Banggai of Central Sulawesi Province. The study aimed to edetermine Mangrove forest characteristic. Plot is used as the methodology which is placed into a  strip with size 10m x 10m for tree level, 5m x 5m for stake level and 2m x 2m for seedling level which set into 20 strip plots along 2 strips. The sampling used is soil sampling which is conducted in aqueous (forward) and in near land area (back). The characteristics of Mangrove forest habitat in Bolobungkang village are loam, sandy loam and dusty loam. The PH ranges 3. 9 – 3. 0 and salinity ranges 2, 73 – 2, 69 per mile. The highest INP for the tree and the stake level is Rhizophora mucronatawith with the value of 116, 86 % and 125, 22 % while the highest of SDR is Rhizophora apiculata with a value of 93, 94 %.

Abstract

Forests are generally known as a resource that is very unique because of the processes of interaction between various constituent components. Every form of forest ecosystem has different capabilities in terms of meeting their needs for environmental conditions including climate. Indonesia is a country that holds the wealth of the largest orchid germplasm in the world. Indonesia has around 6,000 species out of 26,000 world orchid plants. The purpose of the study was to determine the species diversity of orchids in the captivity of Ampera and Karunia Villages, which are found in 6 Sigi Public High Schools and one of the private captives owned by Mr. Sardin. Data collection techniques are carried out in two ways, namely primary data and secondary data. To find out the types of natural orchids found in the captivity of Ampera Village and Karunia Village, Palolo District, Sigi District, descriptive data analysis was used. While to find out the diversity of natural orchid species analyzed using the Shannon-Wienner (H ') Diversity formula. The results showed that the diversity of natural orchid species in the middle of Ampera and Karunia villages was high, with a species diversity index (H ') of 3.25.Keywords: analysis diversity index

Abstract

Tadulako University's Education Forest is one of Sulawesi's endemic wildlife habitats, namely Babyrousa babyrussa. The babirusa population is decreasing due to illegal hunting and illegal mining that destroys wildlife habitat. So it is necessary to conduct research on the composition of the Babirusa habitat vegetation. The study aimed to determine the composition of the Babirusa habitat vegetation in the Educational Forest Zone. Using a method of analysis of double plot vegetation which is placed by Purposive sampling as many as 3 square-shaped observation plots measuring 40 m x 40 m in the spot where the traces of babirusa are found. Each plot is made of 4 sub-plots measuring 20 m x 20 m for tree level, 10 m x 10 m pile level, 5 m x 5 m sapling level and 2 m x 2 seedling level. The results of the study found 29 types in 27 families of which 13 species in 12 families including Babirusa feed. 5 types of plants that comprise vegetation that are always found at the study site, besides the types of Dillenia sp., Are food sources of Babirusa (Babyrousa babyrussa): Pangium edule, Palaqum obtusilfolium Bulq, Lithocarpus elegans (Blume) Hatus. Ex Soepadmo, Calamus sp. The Index of Similarity in 3 study locations, at all vegetation levels ranged from 60.30% - 84.07% or> 75%. So that the composition of the vegetation of the three locations is considered almost the same.Keywords: composition of vegetation, babirusa habitat, forest education
