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

Indonesia is an archipelago country located in Southeast Asia. It has high numbers of species in terms of biodiversity and ecosystem variations. Amphibians and reptiles also exist in the ecosystem of Indonesia. Herpetology is a discipline of zoology that focuses on amphibians and reptiles (herpetofauna). Amphibians and reptiles do not share the same taxonomic group, but they are studied together because they share similar physiological character hence it influences their behavior and metabolism, so they would study with similar method in one discipline. Amphibians and reptiles are widespread across the globe, and they play various roles in the ecosystem. This survey was conducted in morning at 6:00 to 9:00 and in evening at 18:00 to 22:00 at Resort Pondok Ambung SPTN I Pembuang Hulu, Pos Jaga Sungai Buluh Besar, and Pos Jaga Sungai Buluh Kecil Resort Teluk Pulai SPTN III Tanjung Harapan, Taman Nasional Tanjung Puting, between 2020 – 2023. The method was Visual Encounter Survey combined with Road Cruising and/or River Cruising. Herpetofauna photo was taken, and the species was identified by its morphological character based on the field guide. The result is morphology character and protection status description. The species encountered consist of five species of amphibians: Pseudobufo subasper, Polypedates colletti, Polypedates macrotis, Leptobrachium abbotti, Hylarana erythraea, and Pulchrana baramica. Eight species of reptiles: Tomistoma schlegelii, Crocodylus porosus, Draco cornutus, Ptychozoon kuhlii, Varanus salvator, Dendrelaphis sp., Fowlea piscator, and Malayopython reticulatus.

Abstract

Red sweet potato (Ipomoea batatas L.), which contains oligosaccharides, is one of carbohydrates source in Indonesia. The oligosaccharides can benefit the growth of probiotic bacteria and increase the number of probiotic bacteria. Different heating processes can affect the physical and chemical properties of oligosaccharides contained in sweet potatoes. This study aims to assess the survival ability of L. plantarum in a suspension containing red sweet potato as a synbiotic formulation. The observed variables included the total LAB, lactic acid level, and pH values. Red sweet potato substrate with different pretreatments increased the total number of lactic acid bacteria (LAB) and lactic acid levels and decreased the synbiotic pH value. The effect of L. plantarum application on red sweet potatoes resulted atotal acid of 0.45% greater, pH reaching 3, total LAB of 11 log CFU/mL. The best result was pasta with microwave treatment because it can produce simpler sugars, has high anthocyanin levels, and has antioxidant activity.

Abstract

The Gunung Muria forest is one of the important ecosystem value areas in Central Java. This area is relatively well-maintained and in good condition. One strategy for enhancing the protection and preservation of the area is to elevate the status of the forest area's function from that of a protected forest and production forest to that of a nature conservation area within the context of a great forest park. This research is descriptive and exploratory with a qualitative approach. Primary data was obtained from interviews with key people and observations in the field. Secondary data was obtained from literature studies and document studies from related agencies. Data analysis was conducted using a qualitative descriptive method supported by systematic data presentation. The important values of the change in the status of the Mount Muria forest area are 1) protection function, 2)biodiversity, 3) important bird area, and 4) cultural identity. The results show that the Mount Muria forest ecosystem serves as a vital component in the maintenance of the life-support system, acting as a natural barrier for 11 upstream watersheds. The area has high biodiversity and habitat for protected and endangered wildlife. The conversion of the Gunung Muria forest region into a forest park is planned to protect endemic wildlife, specifically the Javan leopard, and their ecology. This change's effectiveness depends on careful planning, community participation, and support from many stakeholders.

Abstract

Gua Nglirip Nature Reserve was initially a conservation area rich in native flora, such as Weeping fig (Ficus benjamina) and Walen (Ficus ribes Reinw.). However, habitat destruction has led to the loss of native flora in the area. This study aimed to analyze ecosystem recovery management in the Gua Nglirip Nature Reserve, specifically emphasizing native flora rehabilitation. This research was conducted using a descriptive qualitative method, data was collected through interviews and document studies from key informants and official reports. The ecosystem recovery process was carried out in two rehabilitation blocks with a total area of 20,504 m², involving the replanting of lost native flora species, such as Weeping tree and Walen, with 836 seedlings planted across both blocks. However, challenges such as fires, prolonged drought, wildlife habitat disturbances, and insufficient monitoring and evaluation, particularly in documenting plant growth data, have caused delays in the ecosystem recovery process. The study results indicate that although progress has been made, improvements in management and better implementation are needed for long-term success.
