Abstract

The success of “Developing Villages” is very much determined by a careful planning that is able to answer problems and anticipate opportunities and challenges that arise carefully and in the process carried out in a participatory manner by involving all stakeholders including the community and village officials/apparatus.The method used in the implementation of the Thematic Village Community Service Program is mentoring. At the end of this activity, a village planning document was obtained in the form of a Village Program Work Plan (RKPD) with the village priority program being the provision of clean water. In addition, students carry out additional activities in the village, namely Takraw Competitions between hamlets as an effort to strengthen the sense of brotherhood among residents.

Abstract

Malaria is endemic in most parts of Indonesia. Anopheles aconitus and Anopheles maculatus are examples of dominant malaria vectors in Indonesia. Plant secondary metabolites can be used as malaria vector control that is safe for the ecosystem, one of which is Durio zibethinus leaves which are thought to have active compounds so that they can be used as botanical larvicides. This study aimed to determine the potency of D. zibethinus leaf extract against An. aconitus and An. maculatus and to determine the concentration, type of extract and content of secondary metabolites of D. zibethinus leaves. Determination of LC50 and LC90 using probit analysis. Maceration and remaceration were used to produce the extract and phytochemical screening to determine the active compound of D. zibethinus. The WHO insecticide bioassay testing procedure was used for the larvicide test. Ethanol extract of D. zibethinus leaf as a larvicide for An. aconitus second and third instar and larvae of An. maculatus second and third instar had LC50 ​​respectively: 480; 520; 510; and 540 ppm and LC90 respectively: 750; 760; 760; and 810 ppm. D. zibethinus leaf aqueous extract as larvicides against larvae of An. aconitus second and third instar and larvae of An. maculatus second and third instar had LC50 values ​​respectively 14,500; 16,400; 22,100; and 23,300 ppm and LC90 respectively, 26,100; 27,200; 30,600; and 33,700 ppm. Ethanol extract of D. zibethinus leaves was more effective as a larvicide. Alkaloid, saponins and tannins were found in the leaves of D. zibethinus through phytochemical screening.

Abstract

This study aims to the determine the application of metacognitive knowledge-based learning on students’ learning outcomes in heredity material grade IXth at Junior High School of SMP Negeri 1 Talaga Jaya. This study employs a quantitative descriptive approach, utilizing a pre-experimental design that includes a single group pretest and posttest design. The subjects consist of grade IXth-group 1 during the odd semester of the 2022/2023 academic year, comprising a total of 30 students. The instruments used in this study consisted of questions based on metacognitive knowledge, lesson plans students’ worksheet, teacher activity sheet, and student activity sheet. The research data are analyzed using the formula of teacher ativity, student activity, individual completeness, pretest and posttest average scores, and students’ N-gain. The result showed that the scores of students’ learning outcomes increased, as observable from the posttest scores, which were higher than the pretest scores. The pretest score obtained at the first meeting was 28.53 and the posttest was 75.07. In the second meeting the pretest score was 21.27 and the posttest was 77.00 for the third meeting the pretest score was 27.00 and the posttest was 78,06. In addition, the N-gain score of students at the first meeting was 0.65 or in the medium category, in the second meeting was 0.71 an in the third meeting was 0.71 or in the high categories

Abstract

Mangroves are plants that grow along the coast and have supporting roots. Mangrove ecosystems in addition to protecting the coast from waves and wind are also suitable areas for marine fauna life. One of the fauna found in mangrove ecosystems is the spadefish. Skinks often shelter near the bodies of crabs in order to make it easier for the fish to find food and stay protected from predators. The attachment relationship between these two species growing in the same environment is called association. This study aims to determine the association of silverfish with crabs in the mangrove ecosystem of Tabongo Village, Dulupi District, Boalemo Regency. The study showed that there were 2 species of silverfish and 3 species of crabs, namely Periopthalmus argentilineatus, Periopthalmus malaccensis, Scylla paramamosain, Uca perplexa, and Uca sp. There are 2 types of associations, namely positive associations and negative associations. Positive association with the highest value was found in the pair Periopthalmus argentilineatus with Uca perplexa with a value of 0.37. While the negative association with the lowest value is found in the pair Peripthalmus malaccensis with Uca.

Abstract

This study aimed to identify the different types of parasites infecting manggabai fish (Glossogobius giurus) in Lake Limboto, in addition to analyzing the intensity, prevalence, and dominance of parasites in the population. Twenty manggabai fish samples were collected from three different locations in Lake Limboto, namely Dembe 1, Tabmela, and Hutuo. The parasite examination process was carried out at the Zoology Laboratory of the Biology Department of Gorontalo State University, focusing on organs such as skin, gills, fins, and digestive organs. The method applied was the native method, which involves direct observation. The identification results showed the presence of three types of parasites in manggabai fish, namely Gyrodactylus sp., Camallanus sp., and Ligula intestinalis. The highest prevalence was recorded for Gyrodactylus sp. at 65%, indicating a significant spread of parasites in the fish population. The parasite intensity of Camallanus sp. from Hutuo at 7. The parasite Ligula intestinalis showed the highest dominance with a value of 44%. Meanwhile, the highest prevalence and intensity values were placed in the frequent and mild categories.

Abstract

Background: Mangrove ecosystems are crucial for maintaining biodiversity, including crab communities, which are vital to the stability of these ecosystems. Crabs contribute to nutrient cycling and the food web, reinforcing the overall ecological health of coastal habitats. This study focuses on the crab communities in the mangrove area of Tabongo Village, Dulupi District, Boalemo Regency, examining how environmental conditions affect their distribution and diversity. Methods: The research involved surveys at three stations representing different mangrove vegetation conditions. Crab species were identified and their diversity and abundance recorded. Environmental parameters, such as temperature, salinity, and pH, were measured, and the diversity index (H') was calculated to assess species diversity and the relationship between crab communities  and environmental factors. Findings: A total of 11 crab species from 4 families were identified, including Uca (Paraleptuca) annulipes and Ocypode ceratophthalmus. The diversity index ranged from 1.3 to 1.6, indicating moderate diversity. Environmental conditions, with temperatures between 32–34 °C, salinity from 13–19 ppt, and pH from 6.5 to 7, were conducive to crab survival. Station III, with healthier mangrove vegetation, supported greater crab diversity and abundance compared to degraded stations. Conclusion: The study highlights the crucial role of healthy mangrove ecosystems in sustaining crab biodiversity and ecosystem stability. It underscores the importance of mangrove conservation for maintaining biodiversity and protecting coastal ecosystems from degradation. Novelty/Originality of this article: By linking the health of mangrove ecosystems to crab diversity and abundance, it emphasizes the direct impact of environmental factors on crab populations. The findings highlight the importance of mangrove conservation not only for species richness but also for maintaining the ecological balance in coastal ecosystems, offering valuable data for future biodiversity management and conservation efforts.
