Abstract

Mangroves play a vital role in maintaining the balance of coastal ecosystems and provide ecological, economic, and social benefits to humans. However, some communities do not yet understand the importance of this ecosystem, resulting in various destructive practices, such as logging for firewood, land conversion to fishponds or salt fields, and dumping of garbage and waste into mangrove areas. If this situation continues, it will have serious impacts, one of which is coastal abrasion, which threatens the lives of coastal communities. To address this issue, this community service activity was conducted with the aim of educating and raising public awareness about the importance of mangrove conservation as an effort to prevent abrasion in coastal areas. The implementation method included interactive lectures, group discussions, and concrete actions such as planting mangroves in coastal areas. This activity involved the active participation of the local community, particularly children and adolescents from the Palo Porong Community Community Center (TBM Palo Porong), as agents of change in environmental conservation. The results of the activity showed an increase in public understanding and awareness of the function and benefits of the mangrove ecosystem. The community began to show behavioral changes that were more concerned with the environment, such as no longer cutting mangroves indiscriminately and participating in mangrove planting and maintenance activities. Furthermore, this activity fosters a spirit of mutual cooperation and social responsibility in preserving coastal natural resources. Therefore, it can be concluded that mangrove conservation education through a participatory approach can increase community ecological awareness and encourage sustainable, environmentally friendly behavior.

Abstract

Pohon ketapang (Terminalia catappa) merupakan tanaman tropis yang tersebar luas di wilayah pesisir Indonesia, termasuk di Kelurahan Waibalun. Pohon ketapang memiliki karakteristik morfologi yang khas dan mudah dikenali, mulai dari bentuk daunnya yang lebar hingga buahnya yang elips. daun ketapang mengandung senyawa flavonoid, tanin, dan alkaloid yang memiliki aktivitas biologi tinggi, termasuk sifat antioksidan dan antimikroba yang kuat. Pemanfaatan sumber daya lokal ini sangat potensial untuk dikembangkan sebagai bahan sediaan farmasi alami, dan juga dikenal sebagai tanaman serbaguna dengan manfaat ekologis dan ekonomisnya. Penelitian ini bertujuan untuk menguji daya hambat ekstrak daun ketapang terhadap pertumbuhan bakteri P.acne. Penelitian dilakasanakan dalam 4 tahap utama, yaitu tahap pengambilan sampel, preparasi sampel, ektraksi, dan uji daya hambat. Sampel daun ketapang diperoleh dari lokasi ekosistem pohon ketapang di pesisir pantai Waibalun. Sampel diekstraksi dengan menggunakan metode maserasi, sedangkan uji daya hambat dilakukan dengan metode difusi cakram dengan menggunakan 4 variasi konsentrasi ekstrak daun ketapang, yaitu 2.5%, 5%, 7.5% dan 10%. Amoxilin sebagai kontrol positif. Hasil penelitian menunjukan bahwa ekstrak daun ketapang memiliki aktivitas antibakteri terhadap bakteri P. acne yang ditandai dengan terbentuknya zona bening di sekitar cakram. Diamenter daya hambat yang terbentuk dari konsentrasi ekstrak 2.5%, 5%, 7.5% dan 10% serta kontrol positif berturut turut sebesar 27,55 mm, 29,25 mm, 31,35 mm, 33,38 mm, 24,25 mm, dari hasil ini aktivitas antibakteri ekstrak daun ketapang tergolong dalam aktivitas sangat kuat.

Abstract

East Flores possesses abundant raw materials for salt production and is recognized as one of Indonesia’s key salt-producing regions. However, salt produced through traditional methods in this area has yet to meet national quality standards. This study aimed to evaluate the organoleptic and physicochemical properties of traditionally produced salt from Kolaka, Tanjung Bunga District, East Flores Regency. Salt samples were collected from traditional markets in East Flores using purposive sampling. Organoleptic assessment (aroma and color) and chemical analysis were conducted, with results compared against the Indonesian National Standard (SNI) for consumable salt. Organoleptic evaluation indicated that the salt corresponded to quality grade K3. Chemical analysis revealed that moisture content and water-insoluble matter did not comply with SNI requirements. Nevertheless, arsenic levels were below the maximum limit, confirming that the salt is safe for human consumption
