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

Cape (Mimusops elengi L.) treeis one of tree species that grows quickly and adapts easily in tropical area. But, the cape tree needs a longer time to get germination becuase of its hard seed skin. Therefore, it needs scarification or earlier treatment in order to fasten the seed germination. The objective of the reseach was to find out both of seed germination and seedling growth of the cape tree (Mimusops elengi L) on some scarification techniques and growing medium. The research was conducted on June to August 2015 in Permanent Seedling of BPDAS Palu – Poso, Tadulako University, Palu. The soil analysis was conducted in Agronomy Laboratory, Forestry Faculty, Tadulako University. The research applied Factorial Pattern of Complete Randomized Design that consisted of 2 factors and repeated 5 times. The first factor was scarification technique that without scarification or control (S0), seed was submerged in cool water for 3x24 hours (S1), submerged in hot water with early temperature 100°C for 15 minutes (S2), and it submerged with KNO3 0,5% for 10 hours (S3). The second factor was growing medium, soil (M0) and soil mixed with hull of rice charcoal (M1), so there were 8 treatments combination, they were S0M0, S0M1, S1M0, S1M1, S2M0, S2M1, S3M0, and S3M1. The result of the research showed that treatment combination of seed scarification that submerged with KNO3 0,5 % for 10 hours by using soil growing medium (S3M0) gave the highest result on percentage parameter of seed germination of 81,1%, the speed of germinationwas 25,44 days, and seedling wet weight was 0,562 gram. The treatment combination of seed that submerged in cool water for 3x24 hours by using growing medium soil mixed with hull of rice (S1M1) gave the highest result on the parameter  length of seedling rootwas 9,4 cm.Keywords : Cape tree(Mimusops elengi L.), Scarification, Seed, Growing Medium

Abstract

Red Jabon is one tree species with high prospects for forest plantation and reforestation plants in Indonesia and expected to meet the demand for wood in the domestic and international markets. Extraction of seeds is one way to maintain seeds quality red Jabon (Anthocephalus macrophyllus (Roxb.) Havil). The use of calcium oxide (Ca(OH)2) which contains the elements calcium (Ca) is one way of extracting the seeds that need to be applied to the Jabon seeds protected by the flesh. This study aims to determine seeds quality of red Jabon on various methods of extractions of seeds so as to obtain an appropriate extraction method to maintain seeds quality of red Jabon. This study uses a completely randomized design (CRD) consisting of four (4) treatment that E0 (without treatment extraction), E1 (extraction dried by sun-drying for two days), E2 (extraction wet by soaking for 24 hours) and E3 (extraction soaking with lime solution 20 g/l for 25 minutes). Each treatment repeated 4 times, so there are 16 experimental units. The parameters measured were the percentage of pure seed, the percentage of moisture content, weight of 1000 grain seeds, germination, the peak value, the average value of daily germination and the value of germination. The results showed that the extraction treatment E3 able to improve the physical quality of seeds plants red Jabon high of 0,021 grams (weight of 1000 grains), 75.886% (purity), 24.114% (dirt seeds) and 5.117% (moisture). E3 extraction treatment was also able to increase seeds viability red Jabon best is 52.2% (germination), 0.508% /day (peak value of germination), 1.74% /day (daily germination value), and 0.885% /day ( the value of germination).Keywords: Anthocephalus macrophyllus (Roxb.)
