Lingkungan dapat digunakan sebagai sumber belajar langsung. Proses pembelajaran yang mempertemukan siswa dengan objek yang dipelajari dapat meningkatkan produktivitas belajar siswa. Penelitian ini bertujuan untuk menganalisis peningkatan minat dan hasil belajar siswa dengan memanfaatkan potensi lingkungan sebagai sumber belajar. Pembelajaran dilaksanakan dengan pendekatan saintifik di lingkungan pesisir. Data minat belajar siswa dianalisis secara deskriptif dari angket observasi respon siswa sebanyak 5 orang dari masing-masing sekolah. Peningkatan hasil belajar siswa dianalisis berdasarkan hasil hitung N-gain skor evaluasi. Respon siswa di sekolah A memperoleh skor persentase 85,5% (positif) dan sekolah B memperoleh skor persentase 87,5% (positif). N-gain peningkatan hasil belajar kognitif siswa di sekolah A adalah 0,42 (sedang) dan siswa di sekolah B adalah 0,79 (tinggi). Hasil penelitian menunjukkan pembelajaran memanfaatkan lingkungan sebagai sumber belajar mampu meningkatkan minat dan hasil belajar kognitif siswa SMA.

Gastropoda tersebar luas di kawasan pesisir, salah satunya pesisir Pulau Sembilan Kotabaru. Kawasan ini masih tergolong alami dan terdapat terumbu karang. Beberapa titik terumbu karang mulai mengalami kerusakan. Terumbu dan batu karang di zona eulitoral merupakan habitat alami gastropoda. Gastropoda terbagi menjadi tiga ordo, dua diantaranya adalah Ordo Mesogastropoda dan Ordo Neogastropoda belum didokumentasikan. Penelitian ini bertujuan untuk melanjutkan dokumentasi spesies gastropoda (Mesogastropoda dan Neogastropoda) dan menganalisis indeks keanekaragamannya. Data dikumpulkan dengan teknik purposive sampling dengan luas plot 1 m2, sebanyak 20 plot, di sepanjang seratus meter mengikuti garis pantai. Data yang dikumpulkan adalah nama spesies dan jumlah individu setiap spesies.­ Berdasarkan data tersebut ditentukan indeks keanekaragaman menggunakan persamaan Shannon-Wienner. Ditemukan lima spesies dari Ordo Mesogastropoda dan dua spesies dari Ordo Neogastropoda.Indeks keanekaragaman (H’) Mesogastropoda dan Neogastropoda adalah 1.620 dengan kategori sedang, artinya ekosistem di kawasan tersebut tergolong stabil. Gastropods are widespread in the coastal area, one of which is the coast of Pulau Sembilan Kotabaru. This area is still relatively natural, and there are coral reefs. Some points of coral reefs began to suffer damage. Reefs and rocks in the eulittoral zone are natural gastropod habitats. Gastropods are divided into three orders, two of which are mesogastropod orders, and the neogastropod order has not been documented. This study aims to continue the documentation of gastropod species (Mesogastropods and Neogastropods) and analyze their diversity index. Data were collected by purposive sampling technique with a plot area of 1 m2, as many as 20 plots, along a hundred meters following the coastline. The data collected is the name of the species and the number of individuals in each species. Based on these data the diversity index is determined using the Shannon-Wiener equation. Five species of the mesogastropod order and two species of the neogastropod order were found. The Mesogastropod and Neogastropod diversity index (H') is 1,620 in the medium category, meaning that the ecosystem in the region is classified as stable.

The cognitive abilities of Indonesian students are still low based on The Learning Curve in 2013, so the quality of education should be improved. One of them with environmental-based learning. Most Indonesians live in coastal areas, and some use snails as alternative dishes. Therefore, snails in coastal areas can be used as a source of learning. Interest in reading Indonesian students is also low, so the need to develop an interesting book and easily understood so that students are interested to read it. So developed a Book of Popular Scientific-based Diversitas Gastropoda in Coastal Areas. This research is the early stage of development research, which is the validation of popular science books. The purpose of this research is to develop a valid popular science book. Validation is done with three experts by giving a validation sheet of popular science books. Validation data were analyzed descriptively categorization. Suggestions and comments from validators become the reference for product revisions. Validation complete when obtaining minimum category valid. The results showed coherence aspect; legibility; active and passive sentences; method; applications and implications; definitions and explanations; and other styles the device obtains very valid category. Aspects of vocabulary; avoid dubious words; and the format obtains a valid category. Based on the results of this study, the popular scientific books developed have met the rules of popular scientific writing that is interesting and easy to understand, so this popular scientific book can be used by the community and students.

Critical thinking in science learning emphasizes students' knowledge and understanding of scientific concepts and processes needed to make decisions in real conditions. Students who have the ability to think critically are expected to be able to face problems and make decisions intelligently and based on information to live a better life. This study aims to improve students' critical thinking skills by developing teaching materials based on local wisdom. The results showed that the learning carried out significantly affected the level of critical thinking of students, both viewed as a whole (z=-4.731; p-value=0.000<0.05) or based on three aspects of critical thinking separately (p-value=0.000<0.05). The results of this study recommend that the use of teaching materials with local wisdom in science learning materials, especially materials that make up the ecosystem, must be optimized, both at the school and university levels.Abstrak Berpikir kritis dalam pembelajaran sains menekankan pada pengetahuan dan pemahaman mahasiswa terhadap konsep-konsep ilmiah dan proses yang diperlukan untuk mengambil keputusan dalam kondisi nyata. Mahasiswa yang memiliki kemampuan berpikir kritis diharapkan mampu menghadapi masalah serta mengambil keputusan secara cerdas dan berbasis informasi agar dapat menjalani kehidupan yang lebih baik. Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis mahasiswa dengan mengembangkan bahan ajar berwawasan kearifan lokal. Hasil penelitian menunjukkan bahwa pembelajaran yang dilakukan mempengaruhi tingkat berpikir kritis mahasiswa secara signifikan, baik dilihat secara keseluruhan (z=-4,731; p-value=0,000<0,05), maupun berdasarkan tiga aspek berpikir kritis secara terpisah (p-value=0,000<0,05). Hasil penelitian ini merekomendasikan agar penggunaan bahan ajar berwawasan kearifan lokal dalam materi pembelajaran sains khususnya materi yang membentuk ekosistem perlu dioptimalkan, baik dalam level sekolah maupun pada tingkat perguruan tinggi.

Competition in the field of education globally is increasingly competitive, but it has not been directly proportional to the development of education in several regions in Indonesia. Students still have difficulty in critical thinking, including the concept of classification of living things, because the teaching materials used are not fully related to the experience and environment of students. This study aims to develop teaching materials for the concept of classification of living things based on local potential. The development is carried out using Tessmer's formative model which includes five stages; 1) self-evaluation (self-evaluation); 2) expert opinion (expert review); 3) Individual trial (one to one); 4) small group trial; and 5) field test. The results showed that by developing a prototype of contextual teaching materials based on local advantages, it was able to increase students' interest, activity, and thinking skills which could be measured by increasing their learning outcomes.Abstrak Persaingan di bidang pendidikan secara global semakin kompetitif, namun belum berbanding lurus dengan perkembangan pendidikan di beberapa daerah di Indonesia. Peserta didik masih mengalami kesulitan dalam berpikir kritis, diantaranya pada konsep klasifikasi makhluk hidup, karena bahan ajar yang digunakan belum sepenuhnya berkaitan dengan pengalaman dan lingkungan hidup peserta didik. Penelitian ini bertujuan untuk mengambangan bahan ajar konsep klasifikasi makhluk hidup berbasis potensi lokal. Pengembangan dilakukan dengan menggunakan model formatif Tessmer yang meliputi lima tahapan; 1) evaluasi diri (self-evaluation); 2) pendapat pakar (expert review); 3) Uji coba perorangan (one to one); 4) uji coba kelompok kecil (small group); dan 5) uji lapangan (field test). Hasil penelitian menunjukkan bahwa dengan dilakukan pengembangan prototype bahan ajar kontekstual berbasis keunggulan lokal mampu meningkatkan minat, aktivitas, dan kemampuan berpikir siswa yang dapat diukur diantaranya dengan meningkatnya hasil belajarnya.
