Bornean banteng is classified as endangered and found only in Borneo island. The existence of a wild population of Bornean Banteng in Belantikan Hulu, in the north-western part of Indonesia’s Central Kalimantan Province, has been confirmed from the results of camera-trap programme since 2013, but its population size has yet to be determined. The study aimed to identify the threats to the banteng population in Belantikan Hulu and describe the conservation efforts that have already been taken there. Although Belantikan Hulu is now one of the priority habitats for conserving banteng in Kalimantan, the area lies outside the nationally-designated conservation area network. Hunting is one of the greatest threats that can lead directly to failure in their population. Local informants were able to describe the location and number of 24 banteng that were killed over a 65-year period, from the 1950’s to 2015. The true number is likely to be much higher, since these data were derived from a sample representing only 30% of the local hunting community, and they did not include information from any outsiders. Logging, mining and shifting cultivation in around banteng habitats are important factors that are currently contributing to the destruction and degradation of their habitats in Belantikan Hulu. Conservation efforts have got a lot of supports from local stakeholders. These efforts have led to a customary regulation being adopted that prohibits hunting of banteng or degradation of their habitats around their key saltlicks and feeding sites, and the creation of local conservation area of 1,700 ha (on land voluntarily released by the logging company) that includes these key sites.

This study aims to determine the diversity of FMA from rhizosphere of cassava, corn, taro and peanut cultivated on peat lands of Rasau Jaya village by using a corn plant host. The research was conducted at the Biology and Soil Biotechnology Laboratory of the Faculty of Agriculture and plastic housings in the experimental garden of the Faculty of Agriculture Untan and lasted from 26 April 2017 until the date of September 15, 2017. The research procedure was carried out by taking samples of soil and roots from the rhizosphere of cassava, corn, taro and peanuts cultivated in peat lands. Soil and root sampling in each rhizosphere was performed at 4 points of observation as replication with a depth of 0-20 cm and a diameter of 20 cm and then put into plastic bags and labeled. The soil samples taken are then used for microscopic analysis (extraction and identification) and soil analysis to determine the chemical properties. Root samples were stained to determine the percentage of colonization. Trapping culture uses corn crops. Furthermore, extraction and spore identification were performed using the same technique with the extraction and identification of soil samples. Observed variables were including percentage of root colonization, spore density, and spore diversity. The results showed that FMA diversity from 4 types of peat land use from rhizosphere of cassava, corn, taro and peanut plants in Rasau Jaya village before and after trapping showed an increase of spore, diversity of FMA type, while the percentage of infected root values showed variation. Observations on the number of spores showed an increase from 37 to 62 per 50 g of soil increased to 60-170 spores per 50 g of soil. Spore type diversity of 10 Glomus types, 1 type of Gigaspora and 4 types of Acaulospora into 13 Glomus types, 3 types of Gigaspora and 4 types of Acaulospora. The highest percentage of infected roots before trapping ranged between 46.89% - 73.33% and after trapping ranged between 77.89% - 95.50%.

This study aims to examine nutrient uptake of N, P, K and physiological responses of maize plants on peat soil due to the treatment of biological fertilizers and types of manure and to find out the interaction between biological fertilizers and types of manure on N, P, K absorption and physiological responses of maize plants peat. The research was carried out at a location located in Rasau Jaya 2 Village, Rasau Jaya District. The study took place from April 4 to August 14, 2018. Research with field experiments was carried out with a 2 x 3 randomized group (RCBD) factorial treatment design with 3 groups. Biological fertilizer factor (M) consists of 2 levels, namely m0 (without biological fertilizer), and m1 (with biological fertilizer). Type of Manure Fertilizer (P) consists of 3 levels, namely p1 (Chicken Manure), p2 (goat manure) and p3 (Cow Manure). Observations were made on root infections, and nutrient uptake N, P, K. Observations on the analysis of plant growth included Leaf Area Index, Net Assimilation Rate and Plant Growth Rate. Data from the observations were analyzed statistically using analysis of variance (F test). Advanced tests using Duncan's multiple range test (DMRT). The results showed that nutrient uptake of N, P, K and physiological processes of maize plants fed with biofertilizer were better than maize plants without biofertilization, the provision of chicken manure resulted in the best nutrient uptake of N, P, K and physiological processes of maize plants compared to goat manure and cow manure fertilizer, giving biofertilizers to all types of manure (chicken manure, goat manure, and cow manure) can increase nutrient uptake of N, P, K and maize physiologis process on peat soil. Keywords : Biofertilizer, manure, nutrient uptake N, P, K, physiological process

Utilization of tidal land as a medium for growing soybean plants is facing several obstacles such as high soil acidity and low soil fertility. Therefore, we need soybean varieties that are able to grow and produce well on the land—tolerant to other threatening factors. This study aims to find the best soybean variety on tidal land type C. The research method used is a Randomized Block Design (RCBD) with 6 The treatments are, A (Burangrang variety), B (Anjasmoro variety), C (Argomulyo variety), D (Dena variety 1), E (Gema variety) and F (Ring 1 variety). The treatments were repeated 4 times each, thus there were 24 experimental units in total. The results revealed that the Anjasmoro variety gives higher yields than the Burangrang, Argomulyo, Ring 1, Dena 1, and Gema varieties, and has the potential to grow well in type C tidal land. Keywords: Yield, Soybean, Tidal land, Varieties

Penelitian ini bertujuan untuk mengetahui pengaruh kompos tandan kosong kelapa sawit terhadap pertumbuhan dan hasil lobak pada tanah aluvial. Penelitian dilaksanakan dikebun percobaan Fakultas Pertanian Universitas Tanjungpura, dilaksanakan pada tanggal 15 April 2014 sampai dengan tanggal 29 Mei 2014. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 4 ulangan, setiap ulangan terdiri dari 4 sampel tanaman jadi terdapat 80 polibag tanaman. Perlakuan yang dimaksud adalah t1 = 5% bahan organik, t2 = 10 % bahan organik, t3 = 15% bahan organik, t4 = 20% bahan organik, t5 = 25% bahan organik. Variabel yang diamati dalam penelitian ini adalah jumlah daun (helai), berat basah bagian atas tanaman (g), berat basah umbi tanaman (g), panjang umbi tanaman (cm), diameter umbi tanaman (cm). Hasil penelitian menunjukkan bahwa pemberian kompos tandan kosong kelapa sawit, berpengaruh nyata terhadap variabel pengamatan jumlah daun pada minggu ke-4, ke-6, berat basah bagian atas tanaman, berat basah umbi pertanaman, panjang umbi pertanaman, dan diameter umbi pertanaman. Tetapi pemberian kompos tandan kosong kelapa sawit berpengaruh tidak nyata terhadap variabel pengamatan jumlah daun pada minggu ke-2. Pemberian 20% bahan organik memberikan pertumbuhan dan hasil lobak yang terbaik.Kata kunci : Aluvial, Kompos Tandan Kosong Kelapa Sawit, Lobak.
