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.)

Abstract

This study aims to determine the soil chemical properties in cacao agroforestry and cacao mixed garden. The research was conducted for three months, October – December, 2017, at Ngata Katuvua Dongi-Dongi, Palolo Sub-district, Sigi District, Central Sulawesi. The study used a survey method, soil samples collected on five points at 0-30cm and 30-60cm depth for each plot, and then compiled into one sample. The soil samples collection are 4 soil sample. The soil samples were analyzed at the Laboratory of Soil Science Unit of the Faculty of Agriculture, Tadulako University. The study results showed that soil chemical properties on cacao agroforestry tend to be better than soil on cacao mixed garden. The Soil chemical properties on cacao agroforestry: pH 6.42, N-total 0.27%, P-available 13.79ppm, K-available 0.26 (cmol (+) kg-1, C-organic 3.69% and CEC 22,34 (cmol (+) kg-1. While the soil chemical properties on the cacao mixed garden: pH 6.20, N-total 0.11%, P-available 6.67ppm, K-available 0.12 (cmol (+) kg-1, C-organic 1.84%, and CEC 13.45 (cmol (+) kg-1.Keywords: soil chemistry, agroforestry, mixed garden.

Abstract

Abstract:This research aimed to support student’s vocabulary building by using matching game for learning specific term in local folklore to the seventh-grade students in academic year 2015/2016. This research was conducted through A-Pre-Experimental design to solve the problems that happened in the class, which was students’ lack of vocabulary related to term in local folklore. The sample of this research was class VII B students which consisted of 34 persons. The researcher used measurement technique to collect the data, while the tool of data collecting was an objective test which consisted of 30 matching test items. The research findings show that matching game improves the students’ vocabulary mastery.In this research, the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted.  It indicates that matching Game enhanced the vocabulary mastery of the seventh-grade students in academic year 2015/2016. In conclusion, matching game is effective to support the students’ learning of specific term in local folklore.Keywords: Vocabulary, Specific Term, Matching Game

Abstract

The potential of agrofrestry to sequestrate carbon varies depending on the natural quality of sites and management practices. Agroforestry is a climate change mitigation activities. The aim of study was to estimate the carbon stock of agroforestry system at adjacent buffer zone of Lore Lindu National Park (LLNP). Research was carried out in two types of agroforestry stands (simple and complex) adjacent LLNP buffer zone in Palolo Sub District, Sigi District, Central Sulawesi. Estimation of biomass of tree, herbs, litter, necromass and root was based on an allometric equation. The carbon storage in soil was estimated based on the carbon organic content and bulk density of soil in30 cm of depth. The results of study showed that the total carbon stored in the simple agroforestry (125.97 MgC ha-1) was significantly lower than in the complex agroforestry (209.39 MgC ha-1). In addition, the aboveground carbon stock biomass (tree, herbaceous, necromass and litter) and belowground carbon stock (root and soil organic) in a simple agroforestry were 42.42 MgC ha-1 and 83.55 MgC ha-1, respectively. Whereas, the aboveground carbon stock biomass and belowground carbon stock in the complex agroforestry were 98.46 MgC ha-1 and 110.93 MgC ha-1, respectively. Based on the carbon stock estimation in six agroforestry plots in the buffer zones of Lore Lindu National Park, the complex agroforestry was likely to be more stable and more longer in storing carbon comparedto the simple agroforestry.Keywords: Agroforestry, biomass, carbon, climate change, Lore Lindu National Park
