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).

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.

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.

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.

In the regional scale of the province in Kalimantan, the spread case appeared in West Kalimantan and East Kalimantan on 18th March 2020, Central Kalimantan on 20th March 2020, South Kalimantan on 22nd March 2020 and North Kalimantan on 29th March 2020. In this case the Covid-19 epidemic was caused by coronavirus disease 2019 (Covid-19). The prediction of the Covid-19 is currently sought. We use the SIR Model to perform basic reproductive value calculations (R0). This model is the mathematic language, interpreted as the number of nativity of a new case due to a person infected with Covid-19 into a fully healthy and potential population for illness or infection by the Covid-19. Using the linear regression, we estimate the value of R0. The value of R0 in Kalimantan region is West Kalimantan (R0 = 1.15), East Kalimantan (R0 = 1.17), Central Kalimantan (R0 = 1.09), South Kalimantan (R0 = 1.24), and North Kalimantan (R0 = 1.20). According to the SIR Model, the highest R0 value is in South Kalimantan, followed by North Kalimantan, East Kalimantan, West Kalimantan, and Central Kalimantan.

Forest and land fires are not a new phenomenon for some areas in Indonesia, such as Kalimantan andSumatra. Riau, South Sumatra, West Kalimantan and Central Kalimantan are among provinces that havebeen suffered from severe forest and land fires every year. One of the natural factors affecting forest andland fires occurrences in Indonesia is climate. This study analyzes the relationship between hotspots andrainfall in Indonesia on 2015-2016. The results show that a large number of hotspots is found in the dryseason when the rainfall was less, i.e., on July - October 2015 and July - August 2016. Statistically, monthlyrainfall and monthly hotspots has a negative correlation (-) with R2 = 42.5% and P-value = 0.001. Theequation built is y = 3182 - 2.50x, where y denotes hotspots and x for rainfall.Key words: forest and land fires, hotspot, rainfall

Violent Conflicts

Several bloody communal conflicts shook some areas in Indonesia from the late 1990s to early 2000s, including widespread violent conflicts in West and Central Kalimantan. Two groups, the Dayaks and the Malays, both asserting their status as indigenous ethnic groups, fought another ethnic group, migrants from Madura (the Madurese). The disturbances began in late February 2001 in Central Kalimantan. Thousands of Dayaks attacked the Madurese. There was violence and killing in almost all villages. The disturbances began in Sampit City and spread to Kuala Kapuas, Pangkalan Bun and Palangka Raya. More than 400 Madurese died and 80 000 people were forced to leave Kalimantan (Cahyono 2004: 47-48).
