Abstract

Hutan mangrove atau mangal adalah sejumlah komunitas tumbuhan pantai tropis dan sub-tropis yang didominasi oleh pohon dan semak tumbuhan bunga (Angiospermae) terestrial yang dapat menginvasi dan tumbuh di lingkungan air laut. Selain magrove juga terdapat Terumbu karang yang merupakan salah satu ekosistem perairan tropik yang sangat produktif. Peran ekologis yang dimainkan terumbu karang adalah sebagai daerah penyedia makanan, daerah asuhan, daerah pertumbuhan dan daerah perlindungan bagi biota-biota yang berasosiasi dengan terumbu karang serta sebagai penyimpan karbon. Terumbu karang sangat berpotensi menyimpan karbon dalam kerangkanya. Ekosistem terumbu karang ini sangat rentan mengalami kerusakan, ada dua penyebab kerusakan terumbu karang, yaitu akibat dari kegiatan manusia dan pengaruh dari alam. Kerusakan terumbu karang telah terjadi di berbagai daerah di Indonesia, termasuk juga di Sumatera Barat. Rusaknya terumbu karang yang berfungsi sebagai pemecah ombak dan pelindung pantai, mengakibatkan daerah di Pesisir Pantai Sumatera Barat terancam bencana gelombang besar dan abrasi. Salah satu upaya yang dilakukan adalah penetapan kawasan konservasi melalui pembentukan daerah konservasi laut.

Abstract

Pengamatan kromosom merupakan salah satu langkah yang dapat dilakukan agar mendapatkan infromasi dasar mengenai genetik. Informasi mengenai kromosom sangat membantu untuk melihat hubungan kekerabatan, pengungkapan variasi, dan upaya untuk melestarikan suatu spesies. Penelitian pada kromosom ikan air tawar telah banyak dilakukan di Indonesia. Namun penelitian terdahulu yang dilakukan hanya terfokus pada jenis ikan tertentu saja tanpa memperlihatkan perbandingan jumlah dan karyotipe dari masing-masing kromosom ikan air tawar tersebut. Metode yang digunakan adalah studi literatur dari berbagai penelitian terkait kromosom ikan air tawar yang ada di Indonesia. Tujuan dari penelitian ini adalah untuk melihat perbedaan jumlah dan karyotipe masing-masing kromosom pada ikan air tawar. Dari hasil analisa diperoleh jumlah kromosom ikan yang bervariasi mulai dari 36 – 98 kromosom. Selain memiliki jumlah kromosom yang berbeda, juga terdapat perbedaan bentuk ataupun karyotipe kromosom dari masing-masing ikan air tawar. Data hasil penelitian dapat digunakan sebagai bahan referensi untuk melihat perbandingan dari jumlah dan karyotipe dari masing-masing kromosom ikan.

Abstract

Mangrove ecosystems provide a variety of ecosystem services, including coastal protection, carbon sequestration, and opportunities for biodiversity. The mangrove ecosystem, which is an intermediate area between sea and land, has a sharp environmental characteristic gradient. The tides of seawater can cause large fluctuations in several environmental factors, especially temperature and salinity so that the animals that survive and thrive in the mangrove ecosystem are animals that have a great tolerance to extreme changes in environmental factors. This study aims to determine and identify the diversity of fauna species in the mangrove ecosystem. The survey location in this study is in the mangrove area of ​​Bungus Bay which is spread over 4 observation points, namely location 1 (Cindakir), location 2 (Kaluang Cove), location 3 (Kabung Labuhan Cino Cove), and location 4 (Pandan Cove) which is mangrove ecosystem as a sub-system of the coastal ecosystem. Based on the results of the field survey, there were no endemic species found in the protected zone on the coast of Bungus Bay. The fauna found in the mangrove ecosystem in the Bungus Bay area is divided into 2 (two) fauna characteristics, namely vertebrates consisting of 5 (five) species, namely aves (birds), reptiles, amphibians, mammals and primates and fish vertebrates. While invertebrates consist of Crustaceans or crabs, carideas or shrimp, molluscs, echinoderms, and polychaeta or worms. The results of the field survey showed that the types of species based on the family characteristics of the fauna found in the mangrove ecosystem at observation location 1 (Cindakir) were less than the number of species found at observation locations 2, 3 and 4 (Kaluang Cove, Kabung Labuhan Cino Cove, and Pandan Cove).

Abstract

Reducing maternal mortality is one of Indonesia's main targets for improving health. By offering antenatal care services for pregnant women at least four times with the standard 10T during pregnancy, efforts are made to reduce maternal mortality. This kind of research uses a phenomenological approach and is qualitative in nature. The purpose of this study is to obtain, obtain a description, analysis, interpretation of the coverage of antenatal care services. Data were obtained from in-depth interviews with 20 informants consisting of the head of the Puskesmas, Coordinator Midwife, Village Midwife, Cadre and pregnant women. The study findings indicate that although antenatal care services at the Agam District Health Center are covered, the policy reference to Minimum Service Standards has not been met in terms of facilities, labor, or funding. The author suggests expanding the access of pregnant women to health workers through the "Ojol for Pregnant Women" activity, because it is concluded that the coverage of antenatal care services at the Agam District Health Center has not reached the Minimum Service Standards and is expected to improve services, especially visits to pregnant women, health education, and improvement of health services. community participation. This activity is in the form of transportation prepared by the community, either two-wheeled or four-wheeled vehicles that are ready to pick up pregnant women to health facilities

Abstract

Information on the ecological status of inland waters is important to know in the framework of management and conservation purposes, including the biota elements of the Macro-zoobenthos community. This study aims to determine the composition and ecology of feeding acro zoobenthos and its relation to the water quality of Lake Maninjau. Lake Maninjau is one of the priority lakes that has an important role both economically and ecologically. Data were collected from journal literacy. There are 34 types of acro zoobenthos with a low diversity index (H= 0.34-0.82). The distribution of each Taxa was less to nearly even (E= 0.30-0.93). The Macro-zoobenthos found belonged to Molluscs, Oligochaeta, EuHirudinea, Insect Larvae, and Crustaceans. Molluscs were the most abundant, spread over 70% of locations and dominated by Corbicula species. The highest abundance is in the Sigiran location. A total of 26 Taxa were characterized by temperature, TDS, and conductivity variables, while the other 8 were characterized by DO and ORP based on CCA results. The feeding Collector ecology group (especially the filter collector) dominates. This indicates that the waters of Lake Maninjau are rich in fine particulate organic matter (FPOM).
