Abstract

Masalah yang berdasarkan pembelajaran Biologi saat ini didominasi model pembelajaran konvensional dan masih kurang bervariasi dalam memanfaatkan lingkungan sekitar sekolah sebagai sumber belajar. Proses pembelajaran tersebut menimbulkan kecenderungan siswa bersikap pasif dalam belajar. Mengatasi masalah ini perlu adanya model pembelajaran yang dapat menarik minat belajar siswa. Tujuan penelitian ini untuk meningkatkan hasil belajar siawa dengan pendekatan JAS dalam konsep identifikasi tumbuhan kelas angiospermae di SMA Negeri 2 Tondano. Penelitian ini adalah penelitian tindakan kelas yang di lakukan dalam dua siklus. Pada Siklus pertama, jumlah siswa yang memenuhi KKM 17 siswa atau 68%, dan tidak tuntas 8 siswa atau 32% pada siklus kedua, jumlah siswa yang memenuhi KKM terdiri 24 siswa atau 96%, dan tidak tuntas 1 siswa atau 4%. Berdasarkan hasil penelitian ini maka disimpulkan bahwa identifikasi morfologi tumbuhan kelas angiospermae dengan pendekatan jelajah alam sekitar (JAS) dapat meningkatkan hasil belajar siswa di SMA Negeri 2 Tondano Kata Kunci: JAS, hasil belajar biologi, keanekaragaman makhluk hidup.

Abstract

Penelitian ini dilatar belakangi masalah yang ditemukan saat observasi awal yaitu hasil belajar siswa kurang dari standar kelulusan. Hal lain yang diduga mempengaruhi hasil belajar adalah penggunaan metode pembelajaran yang tidak sesuai dengan materi pelajaran. Penelitian ini adalah Penelitian Tindakan Kelas yang bertujuan untuk mengetahui apakah penerapan metode pembelajaran inkuiri dapat meningkatkan hasil belajar siswa kelas X IPA 4 SMA Negeri 2 Bitung. Subjek dalam penelitian ini adalah Siswa kelas X IPA 4 semester genap tahun ajaran 2015/ 2016 yang berjumlah 25 orang siswa. Penelitian ini berlangsung dalam 2 siklus, siklus pertama pada materi filum chordata dengan indikator pencapaian kompetensi mengidentifikasi ciri dan klasifikasi dari filum chordata. Dan siklus kedua pada materi filum chordata dengan indikator pencapaian kompetensi kelas vertebrata.Berdasarkan data hasil belajar yang telah diperoleh pada siklus pertama siswa yang tuntas 44 % dan pada siklus yang kedua 88 %. Maka hal ini menunjukan bahwa penerapan metode pembelajaran inkuiri dapat meningkatkan hasil belajar siswa telah melampaui KKM klasikal 80%. Kata Kunci: Hasil Belajar, Biologi, Metode Inkuiri

Abstract

Tree architectural model represents one of the important concepts to quip characteristic takson in plant morphology and plant taxonomic. Every tree grows at the watershed has a typical architectural model and different ability in rainfall transformation such as stemflow, throughfall, and interception. This research explores tree architectural models at upstream Cianjur watersheds in Mt. Gede Pangrango National Park. Sampling conducted by using plot method to chose 15 trees at sub-montana zone to measure IVI and elevation bevel. Results of the research indicate that there are 12 tree architectural models at upstream Cianjur watersheds. At sub-montana and montana zone models the architectural models are ATTIMS (1 sp), FAGERLIND (1 sp), KWAN-KORIBA (1 sp), MASART (1 sp), PETIT (3 sp) PREVOST (2 sp), RAUH (2 sp), ROUX (1 sp), SCARRONE (1 sp), STONE (1 sp,) and THEORETICAL I (1 sp).

Abstract

Payangka fish (Ophieleotris aporos (Bleeker)) is one of the most common fish species in Lake Tondano, North Sulawesi. Due to the availability of this fish throughout the year, it is one of the types of fish consumed by many people. However, the economic value tends to be below. This study diversified payangka fish into nuggets with clove spice (Syzygium aromaticum) and brown seaweed (Sargassum sp) supplementation. The research conducted aims to obtain a proximate profile and fatty acid content of payangka nugget. The research method used is an experimental laboratory method. The study consisted of preparing payangka fish, making payangka nuggets supplemented with clove and seaweed extracts, proximate analysis by gravimetric method and analysis of fatty acid content by gas chromatography method. The results showed that the supplemented payangka nugget had 67% water content, 0.80% ash content, 0.05% total fat, and 10.50% crude fiber. Omega 3 content is 4.75%, while Omega 6 content is 34.16%. Payangka fish nuggets that were supplemented had a higher nutritional content than those without supplementation. Payangka fish nuggets supplemented with clove extract and brown seaweed contain good dietary content.

Abstract

The Girian watershed with a length of 17.5 km is the longest river in Bitung City which flows through a densely populated area as well as various industries such as smoked fish, tofu and tempeh, animal husbandry, agriculture, and industrial fish factories whose waste goes directly to the Girian watershed. The great deal of population activities can have an impact on water quality and the Girian watershed ecosystem. This study aims to analyse the water quality of the Girian watershed caused by domestic waste. This study uses a quantitative descriptive approach and the method used in this study is the Indonesian National Standard (SNI) according to the water quality parameters that have been determined. The results of the analysis of water quality upstream to downstream show that there is a decrease in water quality. Upstream is classified as good when compared to the parameters that have been determined. Densely populated areas begin to experience a decrease in water quality, namely with DO and Oil and Fat that exceeds the predetermined quality standard. As well as estuaries that have concentrations of TSS, NH3-N, Oils and Fats, COD, and BOD that exceed the specified quality standards. The results of the calculation of the pollution index show that station point 1 upstream is classified as good in 4 groups, station point 2 in densely populated areas shows lightly polluted results in group 2, and The Station 3 estuary shows moderate pollution results in group 3

Abstract

Diversity in animals is a variation of the structure, shape, number, and other properties at a particular time and place. Diversity describes a situation that varies from one person to another, objects that occur cause differences in size, shape, texture, and amount. Arthropods are animals with segmented legs, and segments on the body belong to the animals that live both above and below the ground. This research aims to know the diversity and types of ground surface arthropods in the forest surrounding the Department of Biology, Faculty of Mathematics and Natural Science, Manado State University. This research is located in the forest area of the Department of Biology, Faculty of Mathematics and Natural Science, Universitas Negeri Manado, Tonsaru village, South Tondano District, Minahasa Regency, North Sulawesi. Taking data using the pitfall trap method and analyzing using Shannon Wiener diversity index, species richness index, species evenness index, and species dominance. The data collection and collection results obtained as many as 12 genera with a total of 166 individuals. Namely, Myrmica, Carebara, Paraponera, Papederinae, Anisolabis, Hogna, Spirostreptus, Cafius, Phalangium, Opilio, Oxidus, and Pholidoptera. The diversity index value yields 1,11043. The species richness index shows a value of 2,1518. Index the evenness of the species showed a value of 0,44687. The dominance of type indicates a value of 0,457. The level of diversity is moderate, species richness is low, evenness is moderate, and species dominance is low.

Abstract

This research aims to determine the effectiveness of practicum activities to improve student learning outcomes at SMA Negeri 2 Tondano. This type of research is quantitative descriptive research that uses a survey method to describe and explain data based on the reality in the field. The research was carried out by distributing questionnaires to teachers and students, observation sheets, and practical activity sheets with data sources consisting of 30 students of class X Science 1, 30 students of class X Science 2, and biology teachers. Based on the research results, the level of readiness to obtain data for class X IPA 1 At the implementation stage of the practicum activities for class X Science 1 is 91%; the efforts made to improve the quality of practicum implementation are by improving practicum weaknesses such as the availability of tools and materials, good laboratory management, conducting evaluations, arranging implementation schedules and paying attention to laboratory layout in order to carry out practicum optimally. The factors that influence the quality of practicum implementation include student motivation, limited tools and materials, practicum schedule, availability of facilities and infrastructure, teacher's role in practicum activities, and students' active thinking.
