Abstract

The purpose of this study is to examine and analyze the implementation of the principles of Good Corporate Governance (GCG) in publicly listed companies on the IDX and the obstacles faced in its implementation. The indicators for GCG principles are fairness, transparency, accountability, and responsibility. This study uses a sample of companies listed on the Indonesia Stock Exchange (IDX) with the criteria of having published an annual report and a 2018 publication date is available. This study uses a corporate governance index. This research is a descriptive research using qualitative analysis. This study found a fairly good increase every year since the implementation of GCG, not just compliance with rules and regulations, but also a strong commitment and make it a corporate culture. The constraints faced by go public companies are not impossible to fulfill in the future. The process of transforming change from power into checks and balances involving all elements within the company is not an easy process, but it must continue to be observed and challenged by the company and make continuous improvements in the future.

Abstract

Wetlands are suitable habitats for the coastal bird community. One of the important wetlands is located on Jakarta’s North Coast. Here, this study aims to assess the spatial biodiversity of birds in various land covers of wetlands on Jakarta’s North Coast. In total, there were 23 species belonging to 12 bird families. Ardeidae, Rallidae, and Silviidae bird families have more species compared to other families. The biodiversity H' values in the wetlands dominated by mangrove cover were the highest, at 2.527, followed by the wetlands having less mangrove cover and more water bodies and fish ponds only having H’ values equal to 1.811. The arboreal, small-to-medium-sized birds belong to Nectariniidae, Ploceidae, Silviidae, and Dicaeidae were widely distributed across all land cover. In contrast, the wetlands characterized by mangrove cover dominance combined with muddy substrate coasts were dominated by mid-large water birds belong to Anatidae, Scolopacidae, Ciconiidae, Rallidae, Ardeidae, Phalacrocoracidae, Anhingidae, and Alcedinidae. It is recommended to protect the mangroves and reforest the wetlands with mangroves to provide more habitats for the coastal bird community.

Abstract

Amphibians and their geographical distribution are threatened by climate change, including speciesin West Java, Indonesia. It is estimated that 300 amphibian species are threatened, including the familyDicroglossidae. At the same time, information on how climate change impacts amphibian species inIndonesia is very limited. This study aims to assess and model the suitable habitat for the least concernAsian brackish frog, Fejervarya cancrivora (Gravenhorst, 1829), under the CMIP 5 RCP 8.5 futureclimate change scenario by 2070, analyzed using Maximum Entropy (MaxEnt). The models developedwith MaxEnt showed good predictivity, with an AUC value of 0.701. The models that inform theprecipitation of the wettest month, isothermality, and mean diurnal range variables have significantcontributions to make in shaping F. cancrivora geographical distributions. The models confirm that F.cancrivora had shifted its geographical distribution and had gained and lost habitats under a future climatechange scenario by 2070. F. cancrivora will lose 4,428 km2 of its current habitat and will gain 2,673km2 of new habitat. In total, climate change will cause F. cancrivora to lose its habitat by 1,755 km2.

Abstract

The number of cyber attacks on the banking industry in Indonesia is increasing every year, making people reluctant to save their money in banks. The Deposit Insurance Corporation (LPS) protects bank customer data and funds based on the applicable system and law. However, not many people know about the presence of LPS, so outreach and education about legal protection for bank customers is crucial before they have a bank account. High school students who are Generation Z are the right prospective bank customers to carry out outreach and education regarding legal protection for bank customers. Socialization and education were conducted at SMA Negeri 26 Jakarta, where 96 class XI students participated. The normalization gain method measures the effectiveness of socialization and education. The N-Gain test results were obtained at 77.39% using the pre-test and post-test values. These results prove that there has been an increase in students' knowledge about the legal protection of bank customer data and funds. Prospective and bank customers should not have to worry about their money stored in the bank because public funds will remain protected if a cyber attack occurs.

Abstract

We studied the floristic composition and structure of the logged-over peat swamp forest in the PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been set aside by the company. In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect, thus covering a sampled area of 1-ha. The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness. The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth. Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high (3.05) Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46 %). The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium and based on this association combined with high IVs, the two parameters of species characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and Gonystylus bancanus vulnerable, hence they should be protected.

Abstract

RAHMAH, KARTAWINATA, K., NISYAWATI, WARDHANA, W. & NURDIN, E. 2016. Tree species diversity in the lowland forest of the core zone of the Bukit Duabelas National Park, Jambi, Indonesia. Reinwardtia 15(1): 11 - 26. — An analysis of the composition and structure of a one-hectare plot of forest on a lowland hill slope in the eastern core zone of the Bukit Duabelas National Park, Jambi, was conducted in October and November 2012. The objective of the study was to obtain a descriptive account of the structure and tree species composition of a lowland forest in the eastern core zone of the park. The plot was divided into 100 subplots of (10 m × 10 m) each and the seedling subplots (5 m × 5 m) were nested in the sapling subplots. A total of 414 trees were recorded with DBH (Diameter at Breast Height) ?10 cm, representing 113 species and 38 families, with the total BA (Basal Area) of 25.71 m2 and Shannon- Wiener diversity index of 4.29. Prunus arborea with IV (Importance Value) of 19.19 is the dominant species and the other prevalent species were, Dracontomelon dao (IV =11.46) and Hydnocarpus sp. (IV =11.38). A total of 44 species (38.9%) had each density of 1 tree/ha, which may be considered locally rare. Ficus fistulosa had the highest density (24 trees/ha) and Prunus arborea had the highest BA (3.28 m2 = 12.8% of the total). Only 10 species had F (frequency) of 8-18%, of which Hydnocarpus sp. had the highest (18%); the remaining species had F
