The purpose of the blood donation social devotion program were: 1) to assisted the Blood Donor Unit of The Indonesian Red Cross (UTD-PMI) increased blood reserves to fulfil the blood needs in Palangka Raya city, 2) to socialized blood donation activities on the Universitas PGRI Palangka Raya (UPP) for the communities in and around the campus. Blood donation social activities were attended by 99 participants from students of police school (SPN), students, UPP Lecturers, university student organisation board (BEM), student regiment (Menwa), and the general public. By sex participants of this activity were dominated by men (73 people) and the women (26 people). The amount of blood bags that can be collected during this activity were 69 blood bags. Blood donation activities that are attractively packaged, publicized, and involving organizations/institutions can increase the level of community participation.

Teachers are an essential component of education as well a determinant of the quality of education. The Teacher�s professionalism is characterized by improving the learning quality (LQ) through the utilization and optimization of learning technology. Also, the quality of teaching is also supported by a conducive working environment conditions at the school. This study reported the results of research which investigated the correlation between school climate (SC) and learning technology utilization (LTU) with LQ. Sixteen participants from geographic subject teachers at the State Senior High School (PSHS) in Palangka Raya have responded to the questionnaire and recorded their perceptions of SC, LTU, and LQ. Spearman correlation analysis was used to test their correlation. This study revealed a positive relationship between LTU and LQ. As for the SC did not give influence on the LQ at PSHS in Palangka Raya. So that improving the LQ can be done by enhancing the ability of teachers in LTU and use it in teaching and learning activities in the classroom.

General waters of Central Kalimantan with an area of around 2.29 million Ha is a habitat for freshwater fish, both of which have important economic value and ecological value. Diversity of fish species is a potential for fisheries production both as consumption fish, fish traded between regions and ornamental fish. Based on the latest data, there are 267 species of fish in the public waters of Central Kalimantan and 92 species of which are included in the category of ornamental fish species (Central Kalimantan Marine and Fisheries Service, 2010). Batu Lake is located in Sigi Village, Kahayan Tengah District, Pulang Pisau Regency, Central Kalimantan Province. The area of the lake is approximately 12 km2, around the lake there are rafts and settlements, the distance from the capital city of Kahayan Tengah Subdistrict (bukit rawi + 3 km where the lake slightly enters, through a small road. The distance to the lake is about 250 m from the road) province, the condition of the lake is still natural and only used by residents of Tuwung as a place to find livelihoods (looking for fish and other river products) as well as a means of transportation to certain areas in foodplain waters such as the Lake Batu high water fluctuations (volume of water) in a year is very large. Ruaya fish means adjustment, confidence in conditions that benefit existence and for the reproduction of species with active and sometimes passive movements from one place to another. Effendi (1997) groups the family in the interests of spawning, ruaya to enlargement and food areas and refugee homes to avoid da ri place that is in a bad condition. This research is an effort to introduce the potential of freshwater natural resources in the Lake Batu District of Pulang Pisau in the form of ornamental fish. The inventory activity will provide information about potential types of ornamental fish with all the values of their superiority or attraction so that they can become superior commodities. This research was carried out in Batu Lake (2º 08'23.26 "S 113º 57.11'11.97" E) in Sigi Village, Kahayan Tengah District, Pulang Pisau Regency, Central Kalimantan Province. Collection is done by exploring primary and secondary data about the characteristics of biology, water quality. Water quality measurements are carried out directly in the location to obtain primary data, while secondary data is carried out through interviews with the community. The data obtained is then analyzed and explained in qualitative and quantitative descriptive so that it can provide representative information for the development of ornamental fish. The type of ornamental fish caught in the Leerii Trichogaster, Bicirrhis Cryptopterus, Rasbora Argyrotaenia, Parachela Hypophthalmus, Rasbora Caudimaculate

Field research was done to evaluate the financial benefits of forest honeybee business conducted by the local community at Kameloh Baru Village, Taruna Village, and Tumbang Nusa Village in Central Kalimantan. These villages studied are known as a natural honeybee-producing center in Central Kalimantan. The local tribe gathers forest honeybee from Apis dorsata that have done for generations. The results revealed that the income of forest honeybee gathering people in 2015 amounted to IDR six to ten million once harvest. The owner of a tree of honeybee nest has five times higher income than harvesters. However, after a forest fire in 2015, revenues in 2016 and 2017 dropped dramatically to 25% of the previous year. The depletion of natural food resources is a leading factor in honeybee production decrease. On the other hand, the farmers do not have the initiative to cultivate the host trees and reserve natural food resources. Forest honeybee cannot be harvested regularly, although the market demand for forest honeybee is still tremendous. On the other hand, a proper technique of honeybee harvesting did not conduct so that the resulting honeybee quality decreases. Neverthenless, the local tribe can develop sustainable forest honeybee gathering based on their ecological knowledge as incentives for forest conservation.

Daerah aliran Sungai Kahayan merupakan kawasan saat ini berkembang, kondisi aliran Sungai Kahayan, sebagaian besar penduduknya bermukim dan berusaha dibantaran sungai serta langsung membuang limbah ke dalam sungai. Tujuan penelitian ini untuk mengetahui seberapa besar buangan limbah organik masyarakat didaerah aliran Sungai Kahayan.Akibat banyaknya pemukiman disepanjang Sungai Kahayan dan untuk mengetahui kondisi kualitas air Sungai Kahayan serta hubungannya terhadap oksigen terlarut serta parameter lain seperti BOD, Suhu, pH, Kekeruhan. Metode yang digunakan dalam penelitian ini adalah metode studi kasus dengan pendekatan survai. Hasil penelitian yaitu unsur kimia yang paling dominan adalah DO, nilai DO di Sungai Kahayan berkisar antara 2-5 mg/l ini berarti nilai DO daerah aliran Sungai Kahayan memenuhi standar baku mutu kualitas air menurut PP No.32 Tahun 2017, untuk nilai pH yaitu kisaran antara 6-7, kondisi kualitas air di daerah aliran Sungai Kahayan telah mengalami pencemaran sehingga tidak layak diperuntukkan bagi masyarakat sekitar sebagai sarana air bersih.
