Pembelajaran Mitigasi Bencana Banjir Pada Siswa SMPN 8 Kubu Raya
Floods are a serious threat in many regions in Indonesia and have a significant impact on society and the environment, either due to the rainy season or due to ROB floods caused by strong sea tides and large waves, especially in the coastal areas of West Kalimantan. Learning flood disaster mitigation material at school age from an early age is very necessary as a provision for students in implementing the steps or efforts that need to be taken when there is a flood disaster. This community service activity aims to educate students at SMPN 8 Kubu Raya which is located in the coastal area of Kakap Kubu Raya District, regarding flood disaster mitigation. This activity was attended by 40 students from class 2 representatives, using educational lecture learning methods and watching YouTube content together. An effective learning approach involves the use of a variety of resources, including instructional videos. The students' interest during this activity was shown by group discussion activities which took place enthusiastically, a flood disaster simulation using animation in YouTube video content was also an effective method in increasing students' understanding and involvement. Students' active involvement in flood disaster mitigation learning activities can increase their awareness of the importance of preparedness and preventive measures. Based on the evaluation of educational activities carried out by the activity implementing team through questions given regarding educational lecture material and watching YouTube animation videos, it shows that randomly selected participants were able to respond with appropriate and quick answers to these questions
Nutritional Value Composition Of Lamun Fruit Enhalus Acoroides From Samboang Beach, Bulukumba District, Sulawesi Selatan
As the main producer, seagrass leaves are the main food for several marine animals such as turtles and dugongs, while seagrass fruit which contains soft seeds can be consumed as food for humans, but it is not very popular and there is not much information regarding the nutritional content of seagrass fruit. One species of seagrass that is often found in the waters of Samboang Beach, Bulukumba Regency is the Enhalus acoroides species. This research aims to determine the proximate and essential metal content of Enhalus acoroides seagrass fruit taken from Samboang coastal waters, Bulukumba Regency, South Sulawesi. Determination of proximates, namely proteins, was carried out using the Kjeldahl method, fats using the extraction method with n-hexane solvent and essential metals, and while determination of essential metal content using the atomic absorption spectrophotometry method. The results of this research show that the water content is 87%, the ash content is 0.76%, the protein content is 1.2%, the fat content is 0.66% and the carbohydrate content is 10.38%. The essential metal test results show zinc (Zn) levels of 5.32 ppm, iron (Fe) of 7.2 ppm, and cobalt (Co) of 0.11 ppm.

Abstrak
Sebagai produsen utama, daun lamun merupakan makanan utama dari beberapa hewan laut seperti penyu dan dugong sedangkan buah lamun yang mengandung biji yang lunak dapat dikonsumsi sebagai pangan untuk manusia, tetapi belum begitu populer dan informasi terkait kandungan gizi dari buah lamun tersebut belum banyak ditemukan. Salah satu spesies lamun yang banyak ditemukan di perairan Pantai Samboang Kabupaten Bulukumba adalah dari jenis Enhalus acoroides. Penelitian ini bertujuan untuk menentukan kandungan proksimat dan logam esensial dari buah lamun Enhalus acoroides yang diambil dari perairan pantai Samboang Kabupaten Bulukumba Sulawesi Selatan. Penentuan proksimat yaitu protein dilakukan dengan metode kjeldahl, lemak menggunakan metode ekstraksi dengan pelarut n-heksan dan logam esensial, sedangkan penentuan kandungan logam esensial dengan menggunakan metode spektrofotometri serapan atom. Dari hasil penelitian ini menunjukkan kadar air sebesar 87%, kadar abu sebesar 0.76%, kadar protein sebesar 1.2 %, kadar lemak sebesar 0.66% dan kadar karbohidrat sebesar 10.38 %. Pada hasil pengujian logam esensial menunjukkan kadar logam zink (Zn) sebesar 5.32 ppm, besi (Fe) sebesar 7.2 ppm dan kobalt (Co) sebesar 0.11 ppm

COMMUNITY STRUCTURE OF MACROALGAE IN LEMUKUTAN ISLAND WATERS, WEST KALIMANTAN
Macroalgae or known as seaweed is one of the potential resources and is responsible for primary productivity in marine waters. Macroalgae plays an important role in marine ecosystems, provides food, oxygen, and habitat for several types of marine biota. Moreover, macroalgae have been reported as renewable resources in marine environment and widely used in various fields. The biodiversity and abundance of macroalgae are strongly influenced by aquatic environmental factors. Lemukutan Island is the largest inhabited island located in Bengkayang Regency, West Kalimantan and has the potential natural resources, including macroalgae. This Island can become a center for producing macroalgae that can be used to meet food needs both locally and domestically. The main objective of this study were to determine the community structure of macroalgae and the condition of the environmental physico-chemical parameters. The sampling locations were carried out in-situ at three stations and the determination of the sampling site was done by purposive random sampling method, by selecting an area based on the presence of macroalgae. The sampling of macroalgae was carried out using a quadratic transect with size of 10x10 m2 and the water quality parameters were measured using the AZ 8603 of WQC instrument. The study found 6 genera of macroalgae, such as Caulerpa, Halimeda, Padina, Turbinaria, Sargassum, and Gracillaria. Among the identified macroalgae, Phaeophyceae have the highest per cent contribution (50%), and Padina had the highest abundance (29.84 ind/m2). Lemukutan Island waters had a moderate level of diversity, high macroalgae uniformity, and dominance index in the low category. The aquaatic environmental factors influenced the abundance of macroalgae in Lemukutan Island waters.
