Abstract

Protein is a macromolecule having base goods 20 kinds of amino acid. Protein has main role in biological system in every organism, some between it is as catalyst, as conveyor and depositor of other molecule like oxygen, supports mechanically impenetrability system (immunity) body, yields movement of body, as transmitor movement of nerve and controls growth and development. Existence of the biological function becomes base in classification for protein. This article explained about one of type from protein namely collagen. Solution about collagen in this article include;covers special and common of collagen and collagen structure. Conclusion from this article inter alia: collagen is material having strength of spread and structure which is in the form of fibre, collagen is main fibre component in bone, tooth, cartilage, skin layer in derm, tendon cartilage and eyepiece, collagen fibril consisted of polypeptide unit sub called tropokolagen which consist of three polypeptide chains which called helix, existence of collagen that is unsatisfying perfect in the forming can cause disease like scurvy, that marked by venous damage and skin structure.

Abstract

The increasing of human population growth in the world causes increasingly height of requirement of goods and service. Accomplishment requirement of goods and service will be able to fulfilled if production of the goods and service is done on a large scale. Produce of goods and service requires input raw material obtained from exploitation resources of natures which there in ecosystem. The exploitation causes lowering ecosystem service and that thing experiences affecting globally. Global impact of which can be make a phenomenon, it is called global climatic change. In this article explained about some related of degradation ecosystem service and increasing global climate change. Some the things namely: understanding of global climate change, ecosystem and its component and process, degradation of service ecosystem as caused of human activity and degradation of ecosystem service can increase the global climate change. Conclusion in this article are the of global climate change happened, caused of human activity to exploiting source of natures and that activity done to increase product goods and service.

Abstract

This studi aimed to describe about the pattern and bioecology of ferns (Pteridophyta) in the sanctuary area of Ambang mountain, part of east Bolaang Mongondow district. It was a descriptive research through survey method and the data were collected through purposive sampling technique. It was divided into 5 stations; each of them 10 plots of sampling. The data were analyzed with morista index formula. The results indicated that there were 21 kinds of ferns, i.e. Asplenium nidus, Drymoglosum piloselloides, Microsorum pustulatum, Selaginella wildenowii, Adiantum peruvianum, Pyrrosia sp, Angiopteris agustifolia, Polypodium sinuosum, Lygodium sp, Dipteris conjugata, Thelypteris paleata, Davallia trichomanoides, Cyathea sp, Gleichenia linearis, Dicranopteris dichotoma, Goiophlebium persicifolium, Hymenophyllum australe, Blechnum capense, Lycopodium sp.1, Lycopodium sp.2, Dicranopteris linearis. Each of ferns gets 0 which means a clumped dissemination pattern. There ara two bioecology factor; biotic factor (habitus or subtract of pteridophyta, because beside pteridophyta terrestrial, there are pteridophyta epifit too. This petridophyta grow in body of host plant (Eucalypthus urophylla, Leucaena leucocephala, Pandanus tectoricus, Calophyllum inophyllum, Coffea arabica, Eugenia aromaticum).abiotic factor are tempherature, humidity, and light intensity.

Abstract

Environmental quality is resultant from various conditions which caused by event of in natures and also cause of activie of human. One of a real problems related to condition and environmental quality is management of natural resources. In management of natural resources, balance between exploitings and continuity is important prerequisite. Existence of exploiting of natural resources and environment having the character of eksploitatif will affect to environmental quality. Management of natural resources required some policies, two among others is exploiting policy and observation policy. In this article explained about the policies. Conclusion from this article; exploiting of natural resources and environment having the character of eksploitatif, causes the balance and continuity annoyed; required various strategic steps and. action according to development of natural resources and environmental; observation policy of natural resources is interpreted as straightening of law in environmental management and natural resources; coordination effort between between institute which related in exploiting of natural resources is required.

Abstract

Lalat Buah (Diptera: Tephritidae) menyebabkan kerugian dan penurunan produksi tanaman tomat (Solanum lycopersicum). Penelitian bertujuan untuk menganalisis struktur komunitas lalat buah (Diptera: Tephritidae) dan tingkat serangan pada tanaman tomat (S. lycopersicum). Penelitian dilakukan di Desa Ayula Sejahtera, Kab. Bonebolango dan identifikasi morfologi lalat buah di Laboratorium Entomologi Balai Karantina Pertanian Kelas II Gorontalo pada bulan Desember 2022 sampai dengan Januari 2023. Jenis penelitian adalah deskriptif kuantitatif dengan metode survey menggunakan perangkap steiner trap. Analisis data struktur komunitas lalat buah meliputi Indeks Keanekaragaman (H’), Indeks Kemelimpahan (KR), Indeks Kemerataan (E), Indeks Dominansi (D) dan tingkat serangan pada tanaman tomat. Hasil penelitian menunjukkan bahwa pada tanaman tomat ditemukan 278 individu yang terdiri dari 2 spesies yaitu Bactrocera umbrosa dan Bactrocera dorsalis. Berdasarkan nilai indeks keanekaragaman Shannon-Wienner, ada H’= 0,600 yang dikategorikan sebagai keragaman rendah. B. dorsalis memiliki indeks kelimpahan tertinggi dengan nilai 0,712%. Indeks kemerataan (E) lalat buah memiliki nilai E= 0,866 kategori kemerataan tinggi. Indeks dominansi berada pada D= 0,59 dikategorikan dominansi sedang. Tingkat serangan lalat buah terjadi peningkatan dan penurunan serangan dengan kategori tergolong ringan yaitu (11,04%), (9,31), (4,97%), (7,69%), (6,94).

Abstract

This research is an experimental research that aims to determine the effect of the Numbered Head Together (NHT) learning model on biology learning outcomes of SMA N 1 Limboto Barat, Gorontalo on ecosystem material with the Nonequivalent Control Group Design research design. The population in this study consisted of three classes, namely class X MIPA 1 with a total of 20 students and X MIPA 19 with a total of 30 students as an experimental class and class X IPS 1 with a total of 14 students as a control class. The research variable consists of the independent variable, namely the use of Number Head Together (NHT), while the dependent variable is student learning outcomes. Data collection was carried out through pre-test and post-test. Based on the results of the study, it was shown that the average post-test learning outcomes for students in class X MIPA 1 and X MIPA 2 as an experimental class taught using the Numbered Heads Together (NHT) model, obtained an average result of 74.92, while the results the average learning obtained by students of class X IPS 1 as a control class taught using the conventional model is 51.12. Furthermore, the control class experienced an increase in student graduation by 21%, while the experimental class experienced an increase in student graduation by 64%, which means that the value of student learning outcomes increased more than threefold with the treatment of using the Numbered Heads Together (NHT) model, especially in the experimental class.
