Abstract

The main cause of mangrove destruction was due to land convertion to housing, aquaculture, illegal loging. Those uncontroled activities was neglect to consider the environmental preservation. Malakosa is one of the village which has mangrove forest, however most of the forest was declining in number, it is therefore important research on the extent of damage to be done in orderto manage the mangrove forest. This phenomenon had motivated this research to investigate the extend and the caused of mangrove forest destruction in Malakosa village, Balinggi district, Parigi Moutong Regency. This research employ Nested Sampling Method. Data was collected from three path. These includes path 1 at second floodgate, path 2 at first floodgate, and path 3 at third floodgate. Physic and water chemical parameter observations was also conducted at these three different floodgates. The result shows that the extend of mangrove forest destruction at malakosa village is between good to severe range continum, with density rate of 6700 btg/ha (low destruction), 1300 btg/ha (modest destruction), and 100 btg/ha (high destruction). Although the physic and water chemical effects on observation stations was still in good conditions, the salinity parameter and iron (Fe) parameters was found to be above the accepted standard.Keyword: Destruction, Forest, Mangrove

Abstract

Conversion of land use system can affect natural ecological processes such as soil properties. A study was conducted to determine the effects of different land use systems (primary forest, agroforestry and coffea plantation) on soil chemical properties in Lore Lindu National Park area, Bobo village, Palolo district, Sigi regency, Central Sulawesi.We measured these effects by quantifying some chemical soil analysis were done on soil samples taken at two depths (0-30cm and >30-60cm). Soil samples were collected from the field by using steel cylinders at three different land use types; primary forest, agroforestry and coffea plantation, respectively. The results of the study, on one hand, revealed that pH (H2O), C-organic, total N, P-available, total K and cation exchange capacities of the primary forest were 6.43, 2.22 %, 0.17 %, 19.77 mg/100g, 37.36 mg/100g and 30,18 me(+)kg-1, while at agroforestry, pH (H2O), C-organic, total N, P-available, total K and cation exchange capacities were 4.86, 1.61 %, 0.17 %, 19.84 mg/100g, 18.74 mg/100g, 14,56 me(+)kg-1, respectively. Furthermore, pH (H2O), C-organic, total N, P-available, total K and cation exchange capacities of the coffea plantation were 6.49, 1.56 %, 0,17 %, 14.16 mg/100g, 49.69 mg/100g and 2877 me(+)kg-1, respectively.

Abstract

A study on the effects of two Fungi Mycorrhizal Arbuscular (FMA) species and watering interval on the growth and resistance of Aleurites moluccana Willd. Seedlings on drought condition was conducted at the farmers group nursery, Uwemanje village, Kinovaro district, Sigi regency, Central Sulawesi. The experiment was laid out in a Randomized Complete Design (RCD) with factorial pattern. First, species of  FMA consist of three treatments; without mycorrhizal inoculation/control (M0), Gigaspora margarita (M1), Glomus mosseae (M2). Second, watering interval; every day (A0), every three days (A1) and every six days (A2). Observation Parameters consist of seedling height increment, stem diameter increment, and increment of leaf number per plant, fresh weight of shoot and root, dry weight of shoot and root, and seedling quality index. The results showed that interaction between different FMA species and watering interval had significant effect only on the seedling height increment, fresh weight of shoot and root and dry weight of shoot and root, but FMA species and watering interval treatment gave significant difference on the stem diameter increment and increment of leaf number per plant.The highest growth parameters was achieved by Gigaspora margarita inoculation compared to Glomus mosseae and control treatments in all watering intervals. Keywords : Fungi Mycorrhizal Arbuscular, Watering Interval, Seedling growth, Water stress, Aleurites moluccana Willd.
