Abstract

Ekosistem mangrove di Desa Ketapang Raya memiliki nilai ekologis yang tinggi dan berpotensi sebagai sumber belajar IPA, terutama bagi guru dan siswa di sekolah sekitar seperti SMP Gerupuk, Kecamatan Pujud, Lombok Tengah. Terdapat 10 spesies mangrove beserta biota asosiasi (Mollusca, Crustacea, Echinodermata, ikan) yang melimpah. Namun, guru IPA belum memanfaatkan potensi tersebut dalam pembelajaran berbasis lingkungan untuk meningkatkan literasi sains. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemanfaatan nilai ekosistem mangrove sebagai sumber belajar IPA serta menanamkan nilai konservasi lingkungan melalui pendidikan formal. Metode yang digunakan adalah pelatihan, diskusi, dan praktik lapangan. Hasil kegiatan menunjukkan partisipasi aktif siswa dan guru dalam diskusi serta apresiasi terhadap materi pembelajaran berbasis mangrove. Luaran kegiatan berupa publikasi pada jurnal ber-ISSN dan terindeks SINTA.

Abstract

Edu-ecotourism in the context of science learning is an educational approach that integrates the concept of ecotourism into the learning process, which offers an effective way to teach science material contextually, experience-based, and relevant to everyday life and can instill an attitude of caring for the environment around students, so that learning becomes more enjoyable and meaningful. However, the fact in the field is that there are still many schools that have not been able to implement edu-ecotourism-based science learning due to various obstacles including the availability of edu-ecotourism-based teaching materials and the lack of teacher knowledge about edu-ecotourism. From previous research, researchers have developed ecotourism/ethnoscience-based science teaching materials that connect community knowledge of the cultural products of the Sasak, Samawa and Mbojo tribes with chemistry or science materials, but have not been widely implemented in schools. Based on the role of edu-ecotourism in the context of science learning in schools is very important, the implementation of ecotourism-based science teaching materials is necessary. Therefore, the purpose of this study is to analyze the implementation of ecotourism-based science teaching materials at SMPN East Lombok Regency. This study uses a qualitative descriptive approach to describe the existing phenomena in depth regarding the implementation of ecotourism-based science teaching materials at SMPN East Lombok Regency, including the obstacles faced by teachers and students, as well as the learning experiences of students obtained after the learning. The research instrument was the research team with the help of questionnaires, observation sheets and interview guidelines. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed using an interactive model. The implementation of ecotourism-based science teaching materials went very well and was received positively by the majority of teachers. A total of 45 teachers actively tried to use at least two of the five teaching materials socialized in their classroom learning. The results of in-depth interviews with 15 teachers stated that the teaching materials used helped them bridge the gap between the theory in textbooks and the reality that exists in the students' environment. Teachers felt that abstract science concepts became easier for students to understand when they saw their direct application in their culture and local wisdom.

Abstract

The mangrove ecosystem is one of the coastal ecosystems that plays an important role in climate change mitigation due to its ability to absorb and store large amounts of carbon, especially in sediments (below ground carbon). Sedimentary carbon is relatively stable and stored for a long period of time, making its presence an important indicator in blue carbon studies. This study aims to analyze the potential of mangrove sediment carbon storage in Bagek Kembar Village and Cemara Beach, Lembar Selatan Village, West Lombok Regency. The study was conducted from August to December 2025 using a quantitative descriptive method. Sediment sampling was carried out by purposive sampling in three mangrove zones, namely the front, middle, and back zones. In each zone, sediment samples were taken at three depth intervals, namely 0–30 cm, 30–60 cm, and 60–100 cm, resulting in a total of 18 samples analyzed. Analysis of organic matter and sediment carbon content was carried out using the Loss on Ignition (LOI) method, while bulk density was used as a physical parameter of the sediment for calculating sediment carbon stocks. The results of the study showed that the bulk density value of mangrove sediment in Bagek Kembar Village ranged from 0.51–0.62 g/cm³ with an average of 0.57 g/cm³, while at Cemara Beach, Lembar Selatan Village ranged from 0.44–0.69 g/cm³ with an average of 0.60 g/cm³. The carbon stock of mangrove sediment in Bagek Kembar Village was higher than that of Cemara Beach, Lembar Selatan Village. This difference was influenced by the density of mangrove vegetation, the organic matter content of sediment, as well as the environmental characteristics and water dynamics at each location. This study shows that both locations have good potential as sediment carbon stores and need to be managed sustainably.

Abstract

Koi (Cyprinus carpio) are a freshwater ornamental fish with high economic value, thus requiring feed that can support growth and efficient nutrient utilization. The purpose of this study was to examine how adding seaweed extract from Sargassum sp. to food affected the growth and survival of koi. Using a completely randomized design (CRD) with four treatments and three duplicates, the trial was carried out over a 30-day period. P0 (no Sargassum sp. extract applied), P1 (50 mL/kg of feed), P2 (100 mL/kg of feed), and P3 (150 mL/kg of feed) were the treatments. Survival rate, absolute length growth, absolute weight gain, feed conversion ratio (FCR), feed use efficiency (EPP), feed proximate composition, and water quality were among the factors noted. ANOVA at a 95% confidence level was used to evaluate the data, and where significant differences were discovered, Duncan's test was used. The findings demonstrated that while the addition of Sargassum sp. extract had no influence on survival rate, it had a substantial impact on absolute length growth, absolute weight growth, FCR, and EPP (P < 0.05). The greatest absolute weight increase of 62.00 g, the greatest absolute length growth of 15.17 cm, the lowest FCR of 1.09, and the highest EPP of 90.75% were all achieved by treatment P3. Nevertheless, additional testing revealed no discernible differences between P2 and P3. In every treatment group, the fish's survival rate was 100%. Therefore, the development and feed consumption efficiency of koi fish were ideally enhanced by the addition of Sargassum sp. extract at a concentration of 100 mL/kg of feed.

Abstract

Kappaphycus alvarezii is one of the leading commodities in the aquaculture sector due to its potential as a source of carrageenan. This study aimed to analyze the carrageenan content of Kappaphycus alvarezii and to determine the optimum harvest age for obtaining the highest carrageenan yield. The study employed an experimental method using a Completely Randomized Design (CRD) consisting of six harvest-age treatments: P1 (20 days), P2 (25 days), P3 (30 days), P4 (35 days), P5 (40 days), and P6 (45 days), with three replications for each treatment during a 45-day cultivation period. The observed parameters included absolute weight, specific growth rate (SGR), carrageenan yield, tissue histology, and water quality. The results showed that all treatments exhibited increased growth. The highest absolute weight was recorded in the 40-day harvest treatment (P5), reaching 1012 ± 138.32 g, while the highest specific growth rate (SGR) was also observed in P5 at 6.93 ± 0.12% day⁻¹. The highest carrageenan yield of the basal thallus of Kappaphycus alvarezii was obtained in the 20-day harvest treatment (P1), reaching 38.23 ± 8.22%. Histological observations revealed progressive tissue development in the basal thallus with increasing harvest age, characterized by the continued development of the medullary tissue. Throughout the study, water quality parameters remained within the optimal range for the growth of Kappaphycus alvarezii. Based on the results, it can be concluded that different harvest ages had a significant effect (p < 0.05) on the carrageenan yield of the basal thallus of Kappaphycus alvarezii. The average carrageenan yield ranged from 24.25 ± 5.81% to 38.23 ± 8.22%, with the highest yield obtained at the 20-day harvest age.
