Abstract

Penelitian ini bertujuan untuk mengetahui kelimpahan Ikan Manggaba’i (Glossogobius giuris) dan karakteristik fisik dan kimia air di perairan danau Limboto. Penelitian ini merupakan penelitian deskriptif kuantitatif yang stasiun pengamatannya berada di kawasan Keramba Jaring Apung (stasiun I), kawasan eceng gondok (stasiun II), dan bagian tengah danau (stasiun III). Pengambilan sampel ikan dilakukan dengan menggunakan pukat dan bunggo (meriam tradisional dari bambu). Objek dalam penelitian ini adalah Ikan Manggaba’i (Glossogobius giuris) dan diidentifikasi dengan Buku Identifikasi Ikan Air Tawar Indonesia Bagian Barat dan Sulawesi. Data dianalisis dengan menggunakan rumus kelimpahan. Hasil penelitian ini menemukan bahwa stasiun I memiliki nilai kelimpahan 40% dengan kategori sedang, stasiun II memiliki nilai kelimpahan 27% dengan kategori sedang, dan stasiun III memiliki nilai kelimpahan sebesar 31% dengan kategori sedang. Kelimpahan rata-rata Ikan Manggaba’i di perairan Danau Limboto adalah 32,66% atau termasuk dalam kategori sedang. Sedangkan kondisi fisik perairan Danau Limboto masih memenuhi kriteria kelangsungan hidup Ikan Manggaba’i.

Abstract

The introduction of additives and addictive substances for the younger generation, especially the millennial generation, is very important because children's habits, especially when they are teenagers, do snack activities at school and the surrounding environment without having a selective attitude for the sake of health. The habit of snacking and the lack of knowledge and understanding of healthy snacks and the content of foods that are harmful to health make students not have a selective attitude in consuming snacks in the school environment. Additives contained in food, if excessive can have a negative effect on health. Likewise with addictive substances if misused it will cause negative effects for the body. The purpose of this service activity is to introduce additives and addictive substances that are harmful to health for students aged children and adolescents so that they are able to prevent disease, create a selective attitude in consuming food for the sake of health and save our children from abuse of harmful addictive substances. . The method used in this service activity is the lecture method with a participatory approach through 4 stages of activity, namely, opening, giving material, question and answer/discussion and closing. The socialization activity went well, this could be seen from the enthusiasm of the participants in participating in the socialization activity from beginning to end and actively asking questions and discussing. Learners know the types of additives and addictive substances that are harmful to health and know how to prevent abuse of dangerous addictive substances. In addition, it also adds insight and knowledge to participants about additives and addictive substances that are harmful to health so that students have a selective attitude in snacking activities and consuming food and drinks in the school environment and its surroundings.

Abstract

The purpose of this research is to describe the benefits of the campus environment as a source of learning biology. So many learning difficulties experienced by students on campus. Utilization of various learning resources such as the campus environment is an effort to solve the problem of student learning difficulties. By learning directly in the natural environment, the learning experience experienced by students is more meaningful. Through direct learning in nature or the surrounding environment as a source of learning, it is able to make learning experiences concrete so that learning becomes optimal. The campus environment can be used as a learning resource for several relevant subjects. This research is a descriptive research from a literature study emphasizing the potential process analysis method of the environment around campus 4 of State University of Gorontalo as a source of learning biology. Campus 4 environment of Gorontalo State University, Bone Bolango Regency can be used as a learning resource in several subjects such as plant diversity, low-level and high-level plants, mycology, entomology and so on. This is due to the condition of the campus 4 environment of Gorontalo State University which is still beautiful and cool and has many tall and large trees, low-level plants that are still maintained, has many species of fungi and insects and so on.

Abstract

This study aims to describe the effectiveness of using smartphone-based learning media on ecosystem materials in developing students' environmental care attitudes. This study aims to develop textbooks using the value of the structure of mangrove vegetation and the value of carbon uptake. The value of the mangrove vegetation structure value and the value of carbon uptake have been obtained from the results of previous studies conducted in the mangrove area of ​​Tabongo Village, Dulupi District, Boalemo Regency, Gorontalo Province. In this study focused on the development of coastal ecology textbooks based on the value of the mangrove vegetation structure and its carbon absorption value. The method used is the 4-D model (four D) which includes the defining stage, the planning stage (design), the development stage (develop) and the dissemination stage. The dissemination stage is carried out by implementing textbooks that have been developed in coastal ecology lectures. The data was collected using a validation sheet, which includes material validation, design validation, and legibility testing involving biology students. The data obtained were analyzed using the formula for the average validation score, with the eligibility criteria, namely very feasible (3.26 - 4.00), feasible (2.51 - 2.25), quite feasible (1.76 - 2.50), less feasible (1.00 - 1.75). The research results obtained that, the material expert's assessment of all aspects of assessment for textbook validation is 93.75% which means that it has very good quality, because it is in the range of 81% to 100%, the design expert's assessment of all aspects of the assessment for textbook design validation is 91.67 % which means that the design quality is very good, because it is in the range of 81% to 100%, the student response to the quality aspects of textbooks is at a percentage of 94%, meaning this book is included in the very good category because it is in the range of 81 to 100%. Thus, the textbook produced in this study can be used as a reference in coastal ecology courses. Abstrak. Penelitian ini bertujuan untuk mengembangkan buku ajar dengan menggunakan materi nilai struktur vegetasi mangrove dan nilai serapan karbon. Nilai nilai struktur vegetasi mangrove dan nilai serapan karbon telah diperoleh dari hasil penelitian sebelumnya yang dilakukan di kawasan mangrove desa Tabongo Kecamatan Dulupi Kabupaten Boalemo, Provinsi Gorontalo. Dalam penelitian ini difokuskan pada pengembangan buku ajar ekologi pesisir yang berbasis pada nilai struktur vegetasi mangrove dan nilai serapan karbonnya. Metode yang digunakan adalah model 4-D (four D) yang meliputi tahapan pendefinisian (define), tahapan perencanaan (design), tahapan pengembangan (develop) dan tahapan penyebaran (disseminate). Untuk tahapan penyebarluasan dilakukan dengan mengimlementasikan buku ajar yang telah dikembangkan pada kegiatan perkuliahan ekologi pesisir. Pengumpulan data dilakukan dengan menggunakan lembar validasi, yang meliputi validasi materi, validasi desain, dan uji keterbacaan yang melibatkan mahasiswa biologi. Data yang diperoleh dianalisis dengan menggunakan rumus rata-rata skor validasi, dengan kriteria kelayakan yakni sangat layak (3,26 – 4,00),  layak (2.51 – 2.25), cukup layak (1,76 – 2,50),  kurang layak (1,00 – 1,75). Hasil penelitian yang diperoleh bahwa, penilaian ahli materi dari keseluruhan aspek penilaian untuk validasi buku ajar adalah 93.75 % yang berarti memiliki kualitas sangat baik, karena berada pada rentang 81% sampai 100%, penilaian ahli desain keselurah aspek penilaian untuk validasi desain buku ajar adalah 91.67 % yang berarti memiliki kualitas desain sangat baik, karena berada pada rentang 81% sampai 100%, respon mahasiswa untuk aspek kualitas buku ajar berada pada persentase 94 % artinya buku ini termasuk pada kategori sangat baik karena berada pada rentang 81 sampai 100%. Dengan demikian buku ajar yang dihasilkan dalam penelitian ini dapat dimanfaatkan sebagai salah satu referensi dalam mata kuliah ekologi pesisir
