Abstract

Rusa timorensisis native wildlife Indonesia which have protected status that require attention in order to preserve and utilization. This study aimed to preference level of the type of diet, and mineral nutrient content of feed in the conservation area Peucang Island. Data collection was performed by following the daily movement of deer and record all types of plants are edible. Neu indexes was used to scoring of level feed,chi square test was used to distinguish in the level of preference, and inspection of feed nutrients and minerals was done in the laboratory animal science. The results showed Cynodon dactylon, Axonopus compressus, Hibiscus tiliaceus, Dendrolobium umbellatum, Lagerstroemiawhere the types of feed most preferred by the index value of the preference of feed w> 1, there where differences in the choice of feed indicated by the chi-square test χ2count = 23.1850> χ2 (0:05, 10) = 18:31, nutritional value and mineral feed in the forests and grasslands showed no significant difference (p> 0.05). Deer in Peucang have a tendency to choose the type of feed that contains the same nutrients and minerals between feed in the forest or grassland although of a different kind.

Abstract

The purpose of this research is to identify the types and characteristics of mangroves on Gantan Island and to evaluate the environmental conditions around the mangrove locations on the island. Mangrove samples were collected through exploration around Gantan Island by closely observing the various mangrove species, taking direct photographs of leaves, roots, flowers, and fruits, and then describing their characteristics. The research results indicate the presence of 11 plant species, including 6 true mangrove species such as Exoecaria agallocha, Xylocarpus granatum, Bruguiera gymnorhizza, Avicennia alba, Sonneratia caseolaris, and 3 associated mangrove species including Acanthus ilicifolius, Hibiscus tiliaceus, and Terminalia catappa. Additionally, non-mangrove plants like grasses and Casuarinaceae trees were also found. Some observation points, such as points 1 and 7 located directly along the open sea, experienced high sea erosion due to large waves, causing damage to the natural habitat. Local residents have undertaken reforestation efforts to restore the damaged habitat. Observation point 6 also experienced sea erosion as it is situated along a large river. Meanwhile, observation points 2, 3, 4, and 5 are still areas with pristine natural conditions in accordance with the mangrove perpendicular zone.

Abstract

The learning process in food microbiology courses generally uses learning media in the form of powerpoint slides which are still general in nature and have not been able to mobilize students' critical thinking skills. As a result, the student's ability score obtained is in the low category. This study aims to determine the level of validity and practicality of STEAM-based E-booklet media. This type of research is research and development using the ADDIE development model which consists of five stages, but in this case it is carried out until the development stage. The validity test was carried out by giving validation sheets to six experts while the practicality test was carried out by giving questionnaire sheets to lecturers and students. The results of the validity test by material expert validators, media experts and learning design experts obtained an average percentage of 88% with a very valid category. Practicallity test by course lecturers obtained an average percentage of 88,5% and student assessment of 97%. The E-booklet can be used as a learning media for students

Abstract

Microplastics threaten the survival of aquatic organisms including fish in Lake Toba. This study aims to identify the type and abundance of microplastics found in the gills and digestive tract of tilapia (Orochromis mossambicus) in cages and non-cages of Lake Toba, Samosir Regency. Sampling was conducted in February-March 2024 at three stations namely Tanjung Bunga, Palipi, Simarsasar with sampling at each location of 10 caged and non-caged fish each. Extraction of microplastics using the Fenton. Observation parameters included gill weight, gut length, and abundance of microplastics in the gills and digestive tract. The results revealed that the majority of microplastics identified in cages and non-cages were fiber and filament types, with non-cage fish having a higher abundance of microplastics than cage fish.

Abstract

This research aims to Know the level of feasibility teacher response, student’s response and effectiveness of learning resources in the form of Environmental Pollution Booklets based on Local Potential based on material experts, learning experts and design experts. The type of research that will be carried out in this study is development research (Research and Development). This research is focused on developing booklet learning media based on local potential on Environmental Pollution material. The development model used is the 4D model (Define, Design, Development, and Disseminate). The data collection techniques used in this research are interviews, observations, questionnaires or questionnaires and tests. The research results show that the local potential-based environmental pollution booklet learning media that has been developed is declared “Very Feasible” based on the assessment of material experts with the category “Very Feasible” (89.13%), based on learning experts with the category “Very Feasible” (93.18), and based on design experts with the category “Very Feasible” (90, 78%), the results of the effectiveness of the good category which means that the local potential-based booklet developed is effective in improving student learning outcomes, namely there is a difference between pretest and posttest scores with an average pretest score of 54.22 while the average posttest score is 84.06 with an average N-Gain value of 0.64.

Abstract

The threat of decreasing populations of Tor species continues to increase due to intensive fishing, habitat destruction and infrequent cultivation efforts. Monitoring of this group of fish must be carried out routinely to reveal the population conditions of fish. This research aims to reveal the population conditions of fish through an analytical approach to the length-weight relationship and fish otolith size. All fish samples were then taken for otoliths to measure their size and analyzed further using a scanning electron microscope (SEM). The research was conducted in the Tangkahan River, North Sumatra, Indonesia from January-March, 2023. The results showed that 43 samples of T. douronensis, 34 samples of T. tambra, and 24 samples of T. tambroides had b values of 2.853, 2.757, and 2.353, respectively. The b value in this study indicated that the fish had a negative allometric growth pattern. The size of the otoliths of the three Tor species shows that T. tambra has the highest length (the distance measured from the anterior to the posterior of the of sagitta otolith) on average reaching 9.31 mm, while T. tambroides and T. douronensis only reach 1.53 mm and 1.83 mm. The results were confirmed by ANOVA showing significant differences (P 0.05) in the mean value of otolith size based on Tor species, where the otolith size of T. tambra was significantly different compared to the other two species. The condition of Tor species in the Tangkahan River has experienced ecological pressure. This indication was concluded from the results of the analysis of the length-weight relationship of fish which showed b value 3 (negative allometric). The results show that the characteristics and size of the otoliths can differentiate Tor species and facilitate identification efforts related to management and conservation.Keywords:Habitat DestructionNegative AllometricAnterior of Sagitta OtolithPosterior of Sagitta Otolith
