Abstract

Climate change caused by increasing carbon dioxide (CO₂) emissions has become a global issue affecting environmental balance and rising global temperatures. Tropical forest ecosystems, including the Hungayono karst area in Bogani Nani Wartabone National Park, play an important role as carbon sinks through vegetation biomass. This study aims to analyze vegetation density, biomass, carbon content, and carbon sequestration potential in the Hungayono karst ecosystem. The research was conducted using a quantitative descriptive method with purposive sampling techniques at three observation points through the transect quadrat method. Vegetation data were analyzed using allometric equations and IPCC conversion factors. The results showed a tree density of 290 individuals/ha and sapling density of 335 individuals/ha. Total biomass reached 677.79 tons/ha, carbon content was 420.06 tons/ha, and carbon sequestration potential was 1541.63 tons CO₂e/ha. These findings indicate that tree-level vegetation plays a dominant role in carbon storage and climate change mitigation.

Abstract

The growth of cultivated plants is often hampered by soil degradation due to excessive use of chemical inputs. The use of microorganisms such as actinomycetes offers an environmentally friendly alternative, but its appli cation is still limited due to its low viability in the field. This study aims to analyze the colonization ability of encapsulated actinomycetes on the roots of cultivated plants, focusing on parameters such as the ability to infect root tissue, and the ability to induce growth in cultivated plants. Actinomycete isolates were obtained from the rhizosphere of maize plants that exhibit PGPR activity. This study was conducted quantitatively with a descriptive approach. This study used treatments with and without inoculation of encapsulated actinomycetes on maize (Zea mays var. ceratina) and cocoa (Theobroma cacao) plants. The results showed that encapsulated actinomycetes were able to colonize the root systems of maize and cocoa plants, as indicated by the presence of actinomycete filamentous structures on the root surface and within the root tissue. Inoculation with encapsulated actinomycetes induced growth in both plant species, as demonstrated by improvements in all growth parameters. Encapsulated actinomycetes have the potential to be effective biological agents for enhancing plant growth and provide an environmentally friendly technological alternative to support sustainable agriculture.

Abstract

Coastal science learning in Pagimana, Central Sulawesi, has not adequately connected local environmental problems with students’ thinking development and environmental awareness. This study aimed to develop and examine the expert validity of the PjBL-STEAM-IC model, in which IC denotes Innovation and Creativity, for SOLO-based thinking skills and environmental awareness in coastal schools. Using an adapted Borg and Gall research and development procedure, this article reports the needs analysis, hypothetical model design, development of instructional materials and research instruments, expert validation, and Product Revision I. Three validators evaluated the model and its supporting products; their ratings were analysed using Aiken’s V, and their written recommendations were examined descriptively. The developed model comprises six phases linking coastal environmental problems, STEAM-IC project activities, SOLO-based reasoning, and four dimensions of environmental awareness: knowledge, attitude, behaviour, and skills. All validated components were classified as very valid, with Aiken’s V coefficients ranging from 0.902 to 0.961. Expert feedback led to clearer operational syntax, stronger theoretical mapping, more explicit STEAM-IC integration, improved alignment with SOLO-based thinking and environmental awareness, and refinement of the student response questionnaire. The model and its supporting products were therefore considered sufficiently valid to proceed to subsequent classroom field testing.

Abstract

Biology learning on excretory system materials often experiences obstacles due to the abstract nature of the material and the lack of use of interactive learning media. As a result, students tend to be passive and learning outcomes are low. This condition shows the need for digital-based learning media innovations that are able to present visualization and interactivity in the learning process. This study aims to determine the level of validity of Google Sites-based learning media on human excretion system materials. The type of research used is research and development with the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. However, this study is limited to the limited stage of trials. The research instrument is in the form of validation sheets assessed by material experts and media experts. The results of the study showed that the average validation score by material experts was 94.3% and by media experts was 92.5%, both of which were included in the very valid category. Based on these results, it can be concluded that the Google Sites-based learning media developed is suitable for use as a biology learning medium. This media is effective in helping students understand the concept of the excretory system in a more interesting, contextual, and interactive way.

Abstract

This study aimed to describe the condition of coral reefs in the waters of Popaya Island, Mas Popaya Raja Nature Reserve, North Gorontalo Regency, using the Coral Point Count with Excel Extensions (CPCe) method. Data collection was conducted using the Underwater Photo Transect (UPT) method through skin diving along a 50-meter transect at a depth of 3–6 meters. Coral reef conditions were documented using a 60 × 40 cm frame placed alternately on the left and right sides of the transect line at one-meter intervals, resulting in 50 photographs. Data analysis was performed using 30 random points applied to each photograph to classify live and dead substrate categories. Environmental parameters, including water temperature, pH, current velocity, and water clarity, were also measured. The results showed that the environmental conditions of the waters supported coral growth, with a temperature of 28.7°C, pH of 7.8, current velocity of 0.51 m/s, and water clarity of 90%. The percentage of live coral cover was 74.37%, which was categorized as good. The composition of live coral cover was dominated by Acropora Branching (78.21%), followed by Coral Massive (12.34%), Acropora Tabulate (7.10%), and Coral Foliose (2.33%). The diversity index (H' = 1.41) and dominance index (D = 0.48) indicated a moderate category. The mortality index value of 0.10 indicated a low level of coral mortality. It can be concluded that the coral reef ecosystem in the waters of Popaya Island is in good and stable condition.

Abstract

Salt lick merupakan sumber daya habitat yang dapat dimanfaatkan oleh mamalia untuk memperoleh mineral serta melakukan berbagai aktivitas seperti mencari makan, bergerak, dan berinteraksi. Informasi mengenai kunjungan dan perilaku mamalia pada salt lick di Suaka Margasatwa Nantu–Boliyohuto masih terbatas, terutama setelah munculnya African Swine Fever (ASF) pada bentang alam di sekitarnya. Penelitian ini bertujuan mengidentifikasi taksa mamalia yang mengunjungi satu lokasi salt lick serta mendeskripsikan pola perilakunya selama periode pengamatan. Penelitian dilaksanakan pada 23 Februari–23 Maret 2026 menggunakan dua kamera jebak yang beroperasi selama 24 jam dan didukung pengamatan lapangan. Perilaku yang terekam diklasifikasikan berdasarkan ethogram untuk menggambarkan aktivitas mamalia selama berada di lokasi penelitian. Sebanyak lima taksa mamalia terdeteksi, yaitu Macaca hecki, Bubalus depressicornis, Viverra tangalunga, Muridae, dan Sciuridae. Macaca hecki merupakan taksa yang paling sering terdeteksi dan menunjukkan beragam aktivitas, termasuk mencari makan, berjalan, berpindah, kewaspadaan, serta interaksi sosial. Bubalus depressicornis terutama terdeteksi pada malam hari dengan aktivitas berjalan, eksplorasi, kewaspadaan, dan kunjungan ke area salt lick. Viverra tangalunga hanya terdeteksi dalam jumlah terbatas pada periode malam hari, sedangkan Muridae dan Sciuridae menunjukkan deteksi yang relatif sedikit. Kelompok Suidae tidak terdeteksi selama periode penelitian. Hasil ini memberikan gambaran awal mengenai kunjungan dan perilaku mamalia pada satu salt lick di Suaka Margasatwa Nantu–Boliyohuto dan dapat menjadi data dasar untuk pemantauan jangka panjang, termasuk untuk mengevaluasi perubahan aktivitas mamalia dan kemungkinan perubahan keberadaan Suidae di kawasan tersebut.

Abstract

This study aimed to analyze the effect of using Biology learning multimedia based on Smart App Creator (SAC) on the learning outcomes of Grade X students on the topic of Environmental Change. This study employed a quantitative method with a quasi-experimental design using a Non-Equivalent Control Group Design. The sample consisted of 50 Grade X students at SMA Negeri 2 Gorontalo, divided into an experimental class of 25 students and a control class of 25 students. The experimental class received instruction using SAC-based multimedia, while the control class used an E-Book. Data were collected through learning outcome tests in the form of pretest and posttest, and were subsequently analyzed using the Wilcoxon test, Mann-Whitney test, and N-Gain analysis. The results showed that the mean learning outcome of the experimental class increased from 28.00 on the pretest to 77.60 on the posttest, representing an increase of 49.60 points. Meanwhile, the control class increased from 26.72 to 48.32, representing an increase of 21.60 points. The N-Gain analysis showed that the experimental class obtained a mean N-Gain score of 0.69, categorized as moderate, while the control class obtained a mean N-Gain score of 0.29, categorized as low. Based on these results, it can be concluded that the use of Biology learning multimedia based on Smart App Creator has a significant effect on students' learning outcomes on the topic of Environmental Change, with a greater improvement in learning outcomes compared to the use of an E-Book.
