Abstract

This study was conducted to determine morphometric kijing taiwan at several locations in Minahasa District and North Minahasa regency and its association with the abundance of plankton and water quality. Sampling gravestone taiwan and water quality obtained from the four (4 ) locations: Rap Rap Village, BBAT Tatelu North Minahasa Regency, Paleloan and Tataaran II Village, Minahasa regency. Morphometric measurements kijingg taiwan include dimensional measurements and weighing of the shell. Measurement of shell dimensions include length , width , and thickness. Include the weighing of the weighing of the total, shell weight and wet weight of meat. Water quality measurements carried out directly at the sites include measurement of temperature, pH, dissolved oxygen and water base texture, while the identification of plankton carried in Pathology and Clinical Laboratory of Fish Diseases, Faculty of Fisheries and Marine Sciences, University of Sam Ratulangi. Morphometric measurements will be taken in any of 50 individual kijing taiwan each location. The results of morphometric measurements in multiple locations showed uniform size Tataaran II contained in the Village, the Village and Village Paleloan Rap Rap while in BBAT Tatelu uniformity of size only in size from 7-18 to 9-74 cm was caused by Taiwan in the pool because kijing BBAT Tatelu regarded as pest extermination so regularly done. Relationships shell length and total weight kijing taiwan to change at any time is influenced by several factors such as the condition of gonadal maturation , water quality and availability of food in the waters.

Abstract

Abstrak - Serangan penyakit merupakan pemicu kegagalan budidaya. Penyakit yang menyerang organisme budidaya air tawar yaitu penyakit bacterial salah satu agen bakteri yang menginfeksi adalah bakteri P. fluorescens. Penggunaan antibiotik seringkali digunakan untuk mengatasi penyakit yang disebabkan oleh bakteri, sehingga perlu adanya alternatif dengan penggunaan bahan alami. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak lengkuas merah (A. purpurata) terhadap daya hambat bakteri P. fluorescens secara In Vitro. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan, 2 kontrol dan 4 kali ulangan. Perlakuan A (100 ppm), perlakuan B (105 ppm), perlakuan C (110 ppm), perlakuan D (115 ppm), perlakuan E (120 ppm), kontrol positif menggunakan tetracyline 30 ppm, dan kontrol negatif tanpa pemberian ekstrak. Hasil penelitian didapat zona hambat tertinggi pada perlakuan E (120 ppm) dengan rerata zona hambat sebesar 10,53 mm dan terendah pada perlakuan A (100 ppm) dengan rerata zona hambat sebesar 8,15 mm. Zona hambat antar perlakuan menunjukkan grafik linier dengan persamaan y = -3,25 + 0,11x dan koefisien determinasi (R2) yaitu sebesar 0,8552. Kata kunci: Lengkuas Merah (A. purpurata), P. fluorescens, Antibakteri Abstract - Disease attack is a trigger for cultivation failure. Disease tat attack freshwater aquaculture organisms, namely bacterial disease, one of the bacterial agents that infect are P. fluorescens bacteria. The use of antibiotics is still often used to treat diseases caused by bacteria, so there is a need for alternatives to the use of natural ingredients. This study aims to determine effect of red galangal extract (A. pupurata) on inhibitory of P. fluorescens bacteria in vitro. This study used an experimental method with a completely randomized design (CRD) consisting of 5 treatments, 2 controls and 4 replications. Treatment A (100 ppm), treatment B (105 ppm), treatment C (110 ppm), treatment D (115 ppm), treatment E (120 ppm), positive control with 30 ppm tetracyline, and negative control without extract. The results showed that the highest inhibition zone was in treatment E (120 ppm) with an average inhibition zone of 10,53 mm and the lowest was in treatment A (100 ppm) with an average inhibition zone of 8,15 mm. The inhibition zone between treatments shows a linear graph with the equation y = -3,25 + 0,11x and the coefficient of determination (R2) is 0,8552. Key words: Red galangal (A. purpurata), P. fluorescens, Antibacterial

Abstract

Abstract - Waste management issues are a global problem that continue to have negative impacts on the environment. One factor contributing to the increasing amount of waste is the growing diversity of human activities. Coastal areas are highly vulnerable to waste pollution, particularly plastic waste. Plastic waste pollution in coastal marine areas is one of the fastest-growing environmental issues, causing significant negative impacts on marine ecosystems, including the destruction of marine habitats, disruption of the food chain, and the decline in coastal environmental quality. This problem is not only ecological in nature but also has social and economic impacts on coastal communities. This study aims to analyze the understanding and awareness of students at SMPN 2 Semau regarding plastic waste pollution and its implications for coastal marine ecosystems, as well as to examine the effectiveness of educational approaches in improving students’ knowledge and positive attitudes toward plastic waste management. The research method used is descriptive quantitative, with data collected through questionnaires, observations, and environmental outreach activities involving students as the main subjects. The results reveal that although most students already possess basic knowledge about the negative impacts of plastic waste on marine ecosystems, their awareness and involvement in waste management remain relatively low. Environmental education programs in schools can serve as one effective strategy to reduce plastic waste pollution in coastal areas, thus preserving marine ecosystems to support the sustainability of natural resources and the welfare of coastal communities. Keywords: Plastic waste, marine ecosystem, environmental education.

Abstract

Ohoi Hako merupakan desa pesisir di Pulau Kei Besar yang ditempati oleh nelayan yang menjalankan aktivitas perikanan skala kecil, namun kondisi tersebut tidak didukung dengan informasi ilmiah terutama mengenai pola penangkapan ikan yang dilakukan nelayan. Penelitian ini dilakukan dengan tujuan untuk menganalisis pola penangkapan ikan ditinjau dari aspek temporal dan aspek spasial. Penelitian dilakukan pada bulan September 2023 di Ohoi Hako, Kecamatan Kei Besar Selatan Barat, Kabupaten Maluku Tenggara, Maluku. Pengambilan data dilakukan menggunakan teknik wawancara dan pemetaan partisipatif untuk memetakan waktu dan lokasi penangkapan melalui kalender musim dan peta daerah penangkapan. Tool yang digunakan untuk melakukan digitalisasi peta partisipatif adalah ArcGIS. Hasil penelitian menunjukkan aktivitas penangkapan ikan berlangsung sepanjang tahun, dengan konsentrasi tinggi pada bulan Maret – April dan September – Desember, dan rendah pada bulan Januari – Februari dan Mei – Agustus. Gillnet hanya dapat dioperasikan selama enam bulan, sementara hand line dan troll line dapat dioperasikan sepanjang tahun. Lokasi penangkapan ikan meliputi perairan pantai sepanjang pesisir Ohoi Nerong ke Selatan hingga pesisir Ohoi Weduar Fer, meluas ke Saaru Rumaat hingga ke perairan sekitar Tanimbar Kei. Komposisi jenis tangkapan nelayan terdiri dari berbagai jenis ikan, dimana kerapu menjadi target utama tangkapan harian dan tongkol merupakan target utama musiman (Agustus – September).
