Wetlands around the University of Lambung Mangkurat (ULM) Banjarmasin has been the habitat for dragonfly (Odonata). It has the potential to be utilized as a learning resource. A handout is one of the effective learning resources to achieve learning goals. Researchers created a handout to facilitate students to learn about the diversity and activities of Odonata at the wetlands around ULM Banjarmasin. This study aims to describe practicality of the Odonata handout. Research and development of handouts are based on Borg and Gall development model. This research was conducted in ULM Banjarmasin. The research subjects included three expert validation, nine students for small readability tests, and 18 students for small-scale field trials. Data analysis uses descriptive categorical techniques. The practicality of handout is indicated by students’ activity and students’ responses after they use handouts. The handouts based on students’ activity showed very high activity and showed a very strong positive response.

Background Durian of Indonesia, specifically Durio zibethinus, is a potential agricultural commodity for domestic and international markets. However, its quality is still less competitive or significantly lower to fulfill the export market, compared to a similar one from other countries. This study aimed to determine and analyze the genetic diversity and relationship of the exotic durian (Durio spp.) germplasm originally from Kalimantan, Indonesia, using the rbcL marker. Results Based on this marker, the durian germplasm has a low genetic diversity (π%=0.24). It may strongly correspond with the variability sites or mutation present in the region. In this case, the rbcL region of the durian germplasm has generated 23 variable sites with a transition/transversion (Ti/Tv) bias value of 1.00. However, following the phylogenetic and principal component analyses, this germplasm is separated into four main clades and six groups, respectively. In this case, D. zibethinus was very closely related to D. exleyanus. Meanwhile, D. lowianus and D. excelsus were the farthest. In further analysis, 29 durians were very closely related, and the farthest was shown by Durian Burung (D. acutifolius) and Kalih Haliyang (D. kutejensis) as well as Pampaken Burung Kecil (D. kutejensis) and Durian Burung (D. acutifolius) with a divergence coefficient of 0.011. The Pearson correlation analysis confirms that 20 pairs of individual durians have a strong relation, shown by, e.g., Maharawin Hamak and Durian Burung as well as Mantuala Batu Hayam and Durian Burung Besar. Conclusion While the durian has a low genetic diversity, the phylogenetic analyses revealed that this germplasm originally from Kalimantan, Indonesia, shows unique relationships. These findings may provide a beneficial task in supporting the durian genetic conservation and breeding practices in the future, locally and globally.

Mycorrhizae are known as soil fungi because of their habitat in the rooting area (rhizosphere). Nearly 97% of terrestrial plant species interact or symbiotic with mycorrhizae. Symbiosis is formed in the form of an exchange between nutrients and carbohydrates and helps plants absorb P. elements. In Kalimantan, sengon often used as industrial material because it is fast-growing species and widely cultivated by the community. Sengon is a common species planted in mineral soils; however, due to the rising demand of sengon timber, it has been planted on peatlands. This study aims to compare the abundance of arbuscular mycorrhizal spores and identify the morphology of arbuscular mycorrhizal spores associated with Sengon planted on peatlands and mineral soils. This study used a wet sieving method and root staining from the modification of Vierherling et al. 1996 and calculation of root mycorrhizal colonization with gridline techniques. The research used the normality test of data distribution and the T test (Independent sample T test) to determine trends and comparison of differences in the abundance of FMA spores. The study results showed a significant difference in the abundance of AMF in the form of colonization by calculating the percentage of AMF colonization in the sengon root in mineral soils and peatlands of 23.56% 41.67%, respectively. The spore density on mineral soils and peatlands were  18.05 / 50gr and 1.09 / 50gr, respectively. Identification results showed that there were four genera found in peat soil locations, namely the genus Glomus, Gigaspora, Scutellospora, and Acaulospora, while in the mineral soil were found three generas namely genus Glomus, Scutellospora, and Acaulospora. Out of the four generas, the most abundant in both soil types was Glomus.

Abstract. Hidayaturrahmah, Santoso HB, Nurapriana D, Badruzsaufari, Muhamat. 2019. Short Communication: Digenea parasites in giant mudskipper (Periopthalmodon schlosseri) in Kuala Lupak Village, South Kalimantan, Indonesia. Biodiversitas 20: 3782-3787. Parasites are organisms that impart detrimental effects on their host. Monogenea which are generally ectoparasites and digenea which are endoparasites are the most common parasites which invade fish. This research was aimed to find out the existence of monogenean and digenean parasites as well as their species in giant mudskipper or timpakul fish (Periopthalmodon schlosseri) in Kuala Lupak Village, South Kalimantan, Indonesia. Employing 25 giant mudskipper which was randomly collected from Kuala Lupak Village, South Kalimantan, this study explored the presence of ectoparasites and endoparasites on the mucous, fins, gills, intestines, stomach, and meat of the fish. The results showed that only digenean parasites were found in the giant mudskipper (Periopthalmodon schlosseri). The digenean parasites found to come from Opecoeloides genus and Buchepalidae family, metacercariae cysts, and parasites of the nematode phylum. Monogenea parasites were not found due to low fish-density, fish behavior that is rarely in the water, and adequate nutrition which is the opposite of growth-supporting factors of monogenean. Parasitic infection could occur because the fish eat some intermediate hosts of digenea, such as snails and other fish. Besides, the condition of waters that have been contaminated with digenean eggs allows the life cycle of the digenean to continue in fish.

Pemanfaatan teknologi merupakan salah satu upaya untuk mnghadapi revolusi industri 4.0. Istri-istri pembudidaya ikan patin merupakan kelompok warga yang nonproduktif. Dengan adanya pemanfaatn teknologi dalam upaya pemberdayaan perempuan melalui peningkatan kreativitas istri-istri pembudidaya diharapkan dapat memacu semangat istri-istri pembudidaya patin untuk dapat meningkatkan kreativitas sehingga diharapkan menjadi warga yang produktif. Cindai Alus merupakan daerah penghasil ikan patin terbesar di Kalimantan. Metode  yang digunakan adalah survey ke lokasi, sosialisasi program dan pelatihan penggunaan alat-alat.teknologi tepat guna seperti oven untuk pembuatan biskuit skala industry dan mesin pembuat es krim. Berdasarkan hasil survey yang dilakukan tim pengabdian, istri-istri pembudidaya ikan patin di Cindai Alus sudah sering mendapatkan pelatihan pembuatan berbagai macam olahan patin namun belum ada produk yang menarik dan berpotensi dikembangkan bagi warga Cindai Alus dan tidak ada pendampingan setelah dilakukan pelatihan, sehingga warga tidak tertarik untuk menerapkan ilmu yang didapat dari pelatihan. Kreativitas yang diberikan berupa pelatihan cara pembuatan biscuit dan es krim serta  penggunaan oven untuk skala industry dan mesin pembuat es krim dari ikan patin. Hasil dari pemanfaatan teknologi ini adalah menambah motivasi dan semanagat untuk dapat meningkatakan kreativitas yang tidak hanya bermanfaat bagi diri sendiri tetapi mampu meningkatkan perekonomian keluarga.
