DOMINANCE, ASSOCIATION AND DISTRIBUTION PATTERN OF TREE SPECIES IN BURNT FOREST IN EAST KALIMANTAN

Repeated forest fires have high impact on species’ composition. Pioneer species colonize the burnt forest and develop widely up to 30 years after a fire but late-succession species regenerate gradually or even disappear owing to direct impact of fires or other ecological consequences related to fires. Forest restoration through assisted natural regeneration needs information about the state of species’ composition after fire. Species’ dominance is a species’ composition indicator used in this research, with additional information on species’ association and distribution patterns, to understand tree species’ composition after repeated fires. A 1.8-hectare plot divided into 10 x 10 m sub-plots was established in secondary forest in Samboja Research Forest, East Kalimantan. The plot sample was burnt in 1982/1983 and 1997/1998. All trees above 10 cm DBH were measured; leaf specimens were collected for species’ identification at the Herbarium Bogoriense, Cibinong, West Java. For comparison, we used 1981 data observed by the Indonesian Institute of Science, published by Kartawinata et al 2008. The Importance Value Index was used in the data analysis to express species’ dominance. A 2x2 matrix based on presence-absence of species for each sub-plot was used to analyse the association index among species. Variance and average value ratio of certain species present in each sub-plot was expressed in a dispersion index. A chi-square was used to test the significance of the association and dispersion index. Thirteen years after a second fire, pioneer species of Macaranga gigantea were most dominant, followed by Vernonia arborea, a sub-climax species. This indicated that the forest was in an early succession process. Pholidocarpus majadun was consistently dominant before and after the fire. We found 38 pairs of species significantly positively associated and 4801 pairs negatively associated. About 60% species’ association, both negatively and positively, occurred between ‘native species’ (species that exist befores burnt) and ‘non-native species’ (new comer species regenerated after burnt) in the plot sample. A non-native species, Vernonia arborea, associated negatively with the non-native species Tabernaemontana sphaerocarpa, and native species, Oncosperma horridum, Palaquium dasyphyllum and Endiandra rubescens. The distribution pattern of four native species—Artocarpus anisophyllus, Cananga odorata, Croton laevifolius and Macaranga gigantea—changed after repeated fires, from uniform to clumped

From “Hot Mommies” to Differently Abled Mothers: Diverse Portrayals of Mothering in an Indonesian Women’s Magazine

Mothering and motherhood are among two key components of the construction of femininity. This study examined how mothering is embodied and performed by various women in Femina, Indonesia’s most popular women’s magazine, which targets primarily middle- or upper-middle-class women in their twenties and thirties. The sample set consisted of 17 portrayals of women as mothers in Femina during the years 2015 and 2016. We found that Femina depicts various ways in which women can function as mothers while remaining contented and balancing their different roles; in doing so, the magazine encourages a feminine and feminist celebration of mothering. Femina’s representations allow for the bridging and embracing of differences while at the same time constructing an ideal notion of femininity that highlights women’s ability to be successful in each of the multiple domains they enter, including their role as a mother

TREE SPECIES COMPOSITION OF 1.8 HA PLOT SAMBOJA RESEARCH FOREST: 28 YEARS AFTER INITIAL FIRE

Repeated forest fires highly impact on tree species composition. Forest planning requires information about the current condition of species composition. This paper investigates the current tree composition of natural regeneration after repeated forest fires, regeneration process after repeated fires, and strategy of secondary growth related to ecological restoration issues. Re-observation of the 1.8 hectares permanent plot in Samboja Research Forest was conducted in 2011. All trees with diameters above 10 cm at breast height (DBH) were re-numbered and mapped. Herbarium specimen was collected for species identification. Number of taxon was determined, Important Value Index was calculated, species trait of light response was identified based on the references and dispersion index species was calculated. Results show after twenty eight years initial forest fire, 191 species naturally regenerated in the burnt area. Macaranga gigantea, a light demanding pioneer species of Euphorbiaceae was the most dominant species, followed by Vernonia arborea belonging to Asteraceae. Both, M. gigantea and V. arborea had clumped distribution. Eight species identified survived from repeated fires, are Anthocephalus chinensis, Dipterocarpus cornutus, Diospyros borneensis, Eusideroxylon zwageri, Shorea ovalis, Syzygium borneensis, Pholidocarpus majadum and Vatica umbonata. All surviving species was distributed uniformly in the plot. Dominant pioneer species which has grown after repeated fires indicates that the current condition of burnt forest is in the early succession. Protecting forest, assisting natural regeneration and monitoring dominant species are suggested as activities for the ecological restoration

Law Enforcement Against Environmental Pollution by Vehicle Exhaust Emissions

Enforcement of environmental laws relating to emissions from motor vehicle exhaust It is clear from the laws and regulations that the Ministry of Transportation is authorized to act as the implementing agency for periodic motor vehicle inspections and emission testing. The use of motorized vehicles contributes to air pollution which hinders the management and protection of the environment. There are many types of environmental pollution, but in particular air pollution has far-reaching detrimental effects and has a significant impact on environmental quality. By using normative legal research methods and literature studies, namely research that looks at document studies, there are several regulatory matters, including Article 206 of Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Presidential Regulation (Perpres) No. 55 of 2019 concerning the Acceleration of the Battery Electric Vehicle Program for Road Transportation. One of the causes of environmental pollution, especially in the air, is the use of vehicles that use oil (fuel). Electric vehicles are currently the solution to developing environmentally friendly technologies. The government's efforts are carried out by completing emission tests and developing electric vehicles that affect both the environment and vehicle health.Keywords: Law Enforcement, Environment, Emissions, Electric Vehicle
