Abstract

Orchid (Orchidaceae) is one among the plants that grow in Taman Wisata Alam (TWA) Bukit Tangkiling, Central Kalimantan. The lack of information about orchid species in that area makes an inventory crucial. The purpose of this study was to inventory the species of orchids in the TWA Bukit Tangkiling area, as well as to learn about the environmental characteristics and distribution patterns of these plants. The research was conducted from October 2022 to March 2023. This research used the exploratory method and the sample was taken using the purposive sampling technique. Seven orchid species were identified as a result of this study: Acriopsis sp., Arachnis sp., Cymbidium finlaysonianum, Dendrobium crumenatum, Bulbophyllum purpurascens, Bromheadia finlaysoniana, and Dipodium pictum. Five species grow on plant stems (epiphytic), while two species grow on soil (terrestrial). Since each species was discovered less than 100 meters above sea level, they were all categorized as lowland orchid species. Dendrobium crumenatum is distributed randomly. The distribution of Bromheadia finlaysoniana, Bulbophyllum purpurascens, and Cyimbidium finlaysonianum is clustered. While the distribution pattern of the rest could not be determined because only one individual was found.

Abstract

Gibbon (Hylobates funereus) is one of the endemic primates of Borneo Island. H. funereus is declared as endangered species in the IUCN Red List 2020. One of the threats is the loss of habitat caused by deforestation for palm oil plantations. The aim of the research is to assess population density and to estimate population of gibbons at Long Ayap Forest, Berau Regency, East Kalimantan Province. Observation is conducted using strip transect sampling method, carried out at three forest blocks at palm oil plantation of PT Mulia Inti Perkasa (MIP) from September to December 2022 with the total of 27 repetitions. The total gibbon population density is 11-11,96 individuals/km2. Estimation of gibbon population at Long Ayap Forest, Berau Regency, East Kalimantan Province is 17.82 individuals.

Abstract

Paphiopedilum, commonly known as venus slipper or lady slipper, is a genus of orchids that boasts over 70 species, most of which are critically endangered to endangered. These orchids are characterized by the presence of a sac on the flower that serves a unique function closely related to pollination. The pollination of Paphiopedilum is facilitated by bees, which are lured to the flower by producing pheromones such as €-β-farnese and β-pinene. Pouched orchids also produce compounds from the terpenoid group to synthesize a scent that attracts pollinators. Paphiopedilum orchids have evolved a fascinating mechanism to ensure successful pollination. They trap pollinators by making the pollination area slippery so that when the pollinator enters the area, it is likely to slip and try to get out along with the attached pollen. This unique mechanism ensures that the pollen is transferred effectively, increasing the chances of successful fertilization.

Abstract

Birds are ecosystem components that can adapt to human-dominated landscapes. Therefore, they can be found in various man-made landscapes. The Sawarna Beach Tourism Area (SBTA) is a combination of natural and rural landscapes and is developing as a tourist destination. This research aims to analyze the diversity of birds in SBTA. The study was conducted in June 2023 in three types of habitats (beach, farm, and paddy fields). Bird data was taken using the point count method, while habitat data was described according to the main components are vegetation and substrate. Bird data was analyzed quantitatively and qualitatively with (1) species Diversity Index (H'), (2) species Evenness Index (E), and (3) community Similarity Index (IS). There were 32 birds species found from eight orders and 18 families. Of all the species, nine are protected species under Indonesian law, and one species is listed in Appendix II on the CITES-listed animals. The birds found are seabirds e.g. White tern (Gygis alba); shorebirds e.g. Little ringed plover (Charadrius dubius); water birds e.g. Great egret (Ardea alba); as well as terrestrial birds e.g. Streaked weaver (Ploceus manyar) and Javan-green magpie (Cissa thalassina). Variations in bird groups result from differences in habitats. The H' value is 2.39, which is classified as a medium category, and the E value of 0.68 is also classified as a medium category. The IS value indicates that the farm and paddy field habitats have a greater IS value than the beach habitat.

Abstract

Tempeh can be processed into a probiotic drink because it contains Lactic Acid Bacteria (LAB), which are beneficial for the digestive system. A combination of dates and skim milk as prebiotics is required by LAB as a substrate to produce energy and cellular components, and to increase the population to produce sufficient amounts of acid. This study aims to describe the characteristics of LAB present in tempeh probiotic drinks with a combination of dates and skim milk. Isolation was performed using the total plate count (TPC) method with the spread plate technique. Selected isolates were identified macroscopically, microscopically, biochemically, and physiologically. The results showed that the average amount of LAB viable counts was 9.6 x 106 CFU/mL with 8 suspected isolates as LAB. Microscopic observation obtained all 8 isolates were Gram-positive with two round shapes and six-rod shapes. The catalase test results showed all 8 isolates were negative due to the absence of bubbles. The triple sugar iron agar (TSIA) test showed a yellow color, indicating the capability to ferment glucose, lactose, and sucrose. All selected isolates non-motile and positive MR and negative SCA testing. Some of the isolates showed tolerance to salts and acids based on physiological testing. The six most promising LAB isolates showed important characteristics of LAB that should be evaluated when selecting probiotic candidates, namely TEa-4130, TEb-4230, TEb-4130, TEb-3150, TEb-3250, and TEb-4250 isolates.

Abstract

Inventory of seed-borne fungi is a data collection on fungi that infect seeds, this is done to determine the health of the seeds. Seed health testing is very necessary to prevent the spread of disease in the field through seeds. The aim of this research is to inventory and identify fungi carried by chili seeds from Sidodadi Ramunia village. The research method used was isolation of seed-borne fungi which refers to seed health testing methods, namely the Blotter Test method, Rolling Paper method and identification of the fungi obtained to determine the type of fungi that infects chili seeds. The results obtained were that chili seeds from Sidodadi Ramunia Village were infected with seed-borne fungi with the highest percentage being 8% and the lowest being 0.5%. The seed-borne fungi with the highest percentage of infection is the fungus Curvularia sp. The conclusion of this research is that red chili seeds from Sidodadi Ramunia Village, Deli Serdang, North Sumatra were infected with seed-borne fungi, namely Aspergillus sp1., Fusarium sp., Curvularia sp., and Aspergillus sp2. Next, it is necessary to carry out pathogenicity tests and molecular identification of the fungi that have been identified.
