Abstract

ABSTRACTThe seagrass community structure on Pramuka Island is declining due to human activities. The condition of the seagrass community structure can be seen from the stability of the ecosystem, where the diversity of macrozoobenthos in it can be one of the indicators that describe the condition of the seagrass. This study aimed to investigate the association between seagrasses and macrozoobenthos, as well as the distribution of macrozoobenthos in the eastern part of Pramuka Island. The quadrant transect method was used at three observation points with a 100 m transect and 1x1 m² plots at 10 m intervals. The physical and chemical parameters were measured at the start, middle, and end points of each transect using water and sediment samples. Enhalus acoroides dominated four seagrass species found in three transects. Plots near the shoreline and mangrove ecosystems harbored Macrozoobenthos due to sediment richness in the organic matter. The results showed that the correlation between Enhalus acoroides and the macrozoobenthos Holothuria atra had a perfect level of association. Enhalus acoroides plays an important role in providing habitat and food for macrozoobenthos on Pramuka Island. This symbiotic relationship maintains the balance of the seagrass ecosystem on Pramuka Island. The diversity of macrozoobenthos species found on Pramuka Island indicates that this ecosystem is relatively healthy and able to provide various resources for organisms residing in seagrass beds.Keywords: Association, macrozoobenthos, seagrass beds.

Abstract

Kasus Demam Berdarah Dengue masih tinggi di Indonesia, termasuk pada anak usia sekolah dasar yang memiliki tingkat pengetahuan rendah terkait pemberantasan sarang nyamuk. Penelitian ini bertujuan untuk mengetahui perbedaan tingkat pengetahuan siswa setelah diberikan edukasi menggunakan metode ceramah dan video animasi. Desain penelitian adalah kuasi eksperimen dengan pendekatan posttest only control group. Sampel terdiri dari 54 siswa kelas V yang dibagi secara acak ke dalam dua kelompok. Data dikumpulkan menggunakan kuesioner dan dianalisis dengan uji Mann-Whitney. Hasil menunjukkan rata-rata skor pengetahuan kelompok video animasi sebesar 89 dan ceramah sebesar 86, dengan nilai p = 0,137. Tidak terdapat perbedaan yang signifikan antara kedua metode, sehingga keduanya dianggap sama efektif. Edukasi kesehatan di sekolah dapat memanfaatkan kombinasi metode ceramah dan video animasi. Penelitian lanjutan disarankan menggunakan desain pretest-posttest dan sampel yang lebih besar. Dengue fever cases remain high in Indonesia, especially among elementary school students who often have limited knowledge about mosquito nest eradication. This study aimed to examine if there is a difference in students’ knowledge levels after receiving health education through lecture or animated video methods. The study used a quasi-experimental design with a posttest only control group approach. A total of 54 fifth-grade students were randomly assigned to either the lecture or animated video group. Data were collected using a questionnaire and analyzed with the Mann-Whitney test. The results showed that the average knowledge score in the animated video group was 89, while the lecture group scored 86, with a p-value of 0.137. The difference was not statistically significant, indicating that both methods were equally effective. Combining both approaches in school health education could enhance learning outcomes. Further research using a pretest-posttest design and a larger sample size is recommended.

Abstract

This study aims to examine the feeding habits and analyze the stomach contents of the fish caught in the waters of Talaga Jati Taruna. This study was conducted in an exploratory approach by obtaining fish samples from the fishers, followed by morphometric analysis and identification of natural food types in the digestive tract. The results showed that Nile tilapia (Oreochromis niloticus) had a positive allometric growth pattern with a regression coefficient (b) of 3.15 and a determination value of 0.99, indicating that body weight gain was faster than length gain. The relative gut length (RLG) analysis showed that both species are classified as herbivores, with RLG values greater than 3. Diet composition showed that phytoplankton dominated the stomach contents of both species, with the Cyanobacteriia dominating the Nile tilapia diet (IP% = 73.3%) and the Dinophyceae dominant in Mozambique tilapia (IP% = 70.56%). Abiotic parameters were still within optimal ranges to support aquatic life. These findings emphasize the importance of phytoplankton and zooplankton availability as natural food sources in supporting the growth and ecological balance of the Talaga Jati Taruna aquatic ecosystem.
