The nation of Indonesia is the pluralist nation. The plurality suggests the existence of a difference. The understanding and management of plurality would generate a positive force for the development of the nation. On the contrary, when it is not understood and managed properly, the plurality of faiths and cultures can be a destructive factor and trigger a disaster. Conflict and social violence that often occurs between community groups are part of the plurality of religions and cultures that are not managed properly. Religious conflict as happened in Maumere (1995), Surabaya, Situbondo and Tasikmalaya Rengasdengklok (1996), (1997), Solo, Jakarta and Kupang (1998), Poso, Ambon (1999-2002), not only claimed the casualties is not a little, but it has also destroyed hundreds of places of worship (whether a church or Mosque) caught fire and was destroyed. Similarly, notes smelling of ethnic violence, such as certain ethnic violence in West Kalimantan (1933), Central Kalimantan (2000). Necessary preventive measures as early prevention efforts, so that such events do not reoccur in the future. Peace education is an effort bring education more tolerant, understanding the diversity of religions, ethnicities, and cultures.

We describe a new Hoya species from Central Kalimantan, H. buntokensis, and a new subspecies of H. wallichii from West Kalimantan, Hoya wallichii subsp. tenebrosa. Hoya buntokensis is part of a group of four species that form specialised leaf structures harbouring ants (here defined as megadomatia), and it is most similar to H. undulata. Hoya buntokensis differs from H. undulata in lamina margin (flat vs undulate); shape of corona lobes outer processes (fan shaped vs elliptic), and in the pollinarium morphology (corpusculum larger than pollinia vs corpusculum smaller than pollinia). Both H. wallichii subsp. wallichii and H. wallichii subsp. tenebrosa are slender plants with ovate to oblong, thinly coriaceous glabrous leaves, slender peduncles with 1 or 2 flowers open at a time, and broadly campanulate corollas. Hoya wallichii subsp. tenebrosa differs from H. wallichii subsp. wallichii in corolla colour (dark purple with a paler edge vs white-cream), corona lobe shape and surface (broadly elliptic, spreading and with a minute inner process, almost black with a velvety surface vs kidney-shaped, erect and with a well-developed acuminate inner process, purple with a shiny surface).

Study of carbon dioxide emissions in different types of peatlands use in Central and West Kalimantan has been conducted in January-June 2006 and January-April 2007. The study represents 4 types of land use in Central Kalimantan as treatment: 5 years for chinesse cabbage, 10 years for chinesse cabbage, 5 years for sweet corns, and 10 years for sweet corns. As for the treatments in West Kalimantan, they include corn field, Aloe vera field, oil palm plantation, and rubber plantation. Carbon dioxide was measured using infrared gas analysis (model EGM-4, PP systems, Hitchin, UK). In Central Kalimantan, the highest CO2 is emitted from sweet corn plants (arable land for 10 years) by 0.79 g CO2/m2/hour, chinesse cabbage plants (for 5 years) by 0.73 g CO2/m2/hour, chinesse cabbage plants (for 10 years) by 0.67 g CO2/m2/hour and, the least, sweet corn plants (for 5 years) by 0.41 g CO2/m2/hour. The highest CO2 emission from West Kalimantan is released from rubber plants at 1.22 g CO2/m2/hour, followed by palm oil plants by 0.96 g CO2/m2/hour, Aloe vera plants by 0.68 g CO2/m2/hour and corn plants by 0.35 g CO2/m2/hour. Groundwater table depth are the most important factors among other factors that influence CO2 emissions. Groundwater table depth indicated a positive correlation with CO2 emissions in all types of peatlands use. C-organic production of sweet corn plants at 11.66 t C/ha/year is higher than that of chinesse cabbage plants at 1.64 t C/ha /year. Corn plants produce organic-C was 11.66 t C/ha/year, equivalent to the amount of loss of C through CO2 emissions by 11.29 t C/ha/year.Keywords: peat, types of land use, carbon, CO2 emission

The research aims to classify the settlements along the river banks by province. To solve this problem, the researchers applied the K-Means Algorithm method. Where the source of research data was collected based on documents explaining the number of villages / sub-districts according to the existence of settlements on the river banks produced by the Central Statistics Agency (BPS). The data used in the study are data from 2014 - 2018 which consists of 34 provinces. The data will be processed by clustering in 2 clusters, namely the settlement level cluster on the high riverbank and the settlement level cluster on the low riverbank. The high cluster consists of 11 data, namely the provinces of Aceh, North Sumatra, Jambi, South Sumatra, West Java, Central Java, East Java, West Kalimantan, Central Kalimantan, South Kalimantan, and South Sulawesi. By conducting the research, it can provide input and as a solution to related parties in charge of dealing with settlement problems along the river banks, especially for the government, in order to get more attention in provinces with high riverbank settlement rates.

Abstract. Sapari I, Perwitasari-Farajallah D, Utami Atmoko SS. 2019. The Bornean orangutan (Pongo pygmaeus wurmbii) density in a logging concession of Hulu Belantikan, Central Kalimantan, Indonesia. Biodiversitas 20: 878-883. The Bornean orangutan is currently categorized as a critically endangered species. It is found in natural forests in Borneo, where about 78% of the total population is found outside protected areas, of which 29% is in logging concessions. This study aimed to analyze the density of the orangutan population and the abundance of fruiting plants in a logging concession and Protection Forest (Hutan Lindung) in the Hulu Belantikan forests in Lamandau District, Central Kalimantan, Indonesia. Research and data collection was conducted between December 2013 to October 2014. Orangutan population density was calculated using line transect methodology based on nest counts. Abundance of fruit plants was calculated using the fruit trail method. The highest orangutan density, 4.8 individuals/km2, was found in Protection Forest; and the lowest density, 0.4 individuals/km2, was in [Sopanan] the 2013 logging block. Observations in the logging area indicated that selective logging could alter the structure and gap of the canopy and reduce the proportion of large trees. Changes in forest structure resulted in negative effects on the density of the orangutan population. The remaining degraded forests can still be a valuable resource for the orangutan. As long as the disturbance is not intensive, orangutans will retain access to the less disturbed forest nearby and to forests that are still connected to primary forests. The existence of Protection Forest and old logged-over forests around logging blocks are very important for conservation, providing refugia for orangutans and other species when logging occurs.

AbstractAround the recent turn of the century, violent clashes between Madurese and other ethnic groups took place in the provinces of West and Central Kalimantan. At least 1200 Madurese were killed, with several hundred thousands internally displaced. However, in the provinces of South and East Kalimantan, which also have Madurese minorities, such eruptions of violence did not occur. To reach a better understanding of the background, conditions and causes of such ethnic violence, we have compared the relationships between the Madurese and other population groups in conflict-ridden West Kalimantan and conflictfree East Kalimantan. The comparison shows that there are significant dissimilarities between the two regions with regard to the ethnic composition of the population, cultural attitudes, access to natural resources and political competition. Together with the negative characteristics attributed to the Madurese by other groups, these can largely explain why this minority, during the recent regime change, became the target of the frustrations and aspirations of others in the western part of Kalimantan but not in the eastern part.
