Aneka ragam buah-buahan segar diciptakan Sang Khalik untuk umat manusia. Di antara sekian banyak buah-buahan itu, salah satu yang disebutkan Allah SWT dalam Alquran. Adalah buah tin, zaitun, delima, anggur, dan kurma. Untuk itulah kita sebagai muslim perlu men- getahui zat-zat yang terkandung dalam buah tersebut, se- hingga dapat memanfaatkan buah tersebut dengan sebaik- baiknya. Tidak ada sekecil apa pun Allah ciptaan jika tidak membawa kemanfaatan bagi manusia.
Abstract. This research purposed to investigate the effect of integrated science model and its implementation in learning by Unity of Science in Basic Biology courses to improve students' critical thinking. This method research is a quasiexperimental with experimental design posttest only control group design. The population was all students of the first semester Biology, 2015/2016 academic year with consists of two classes. Samples were taken with a simple random sampling technique. The data was collected using an open essay tests and observation of critical thinking skills. Data were analyzed with descriptive analysis and MANOVA test. The results showed as follows: (1) There are differences between the understanding of basic biology concepts students learn to use the integrated science model of with students who learn to use the direct teaching model (F = 7.783; p <0.05), (2) there are differences in thinking skills critical significantly between students learning with integrated science model and its implementation in Unity of science learning with students who learn to use the direct teaching model (F = 11.11, p <0.05).
Islamic economy is a progressive and dynamic economy. Various new theories have been raised as an offer for the development of Islamic economics, one of which was carried out by Abbas Mirakhor. This article discusses the main principles of the economic system to the role of the state; an offer of Abbas Mirakhor to Islamic economics. To know more deeply the Islamic economic thoughts offered by Abbas Mirakhor, from the main principles of the economic system to the role of the state in the economy. This article uses a type of qualitative research using library research. The results of this study indicate that Abbas is a practitioner of Islamic economics and finance who has a good reputation in the world, both Islam and the West and is considered a reformer in the Islamic economy, and is part of the Iqtishad school of thought. In the field of the Islamic economic system, Mirakhor argues that the main principle of the Islamic economic system requires distribution in two mechanisms, namely freedom, and justice, without which prosperity will not be realized. Therefore, there is a need for a hermeneutical approach to answering various problems that occur in the Islamic economic system. In the context of the state, according to Mirakhor, the state has a very significant role in the welfare of society, especially through its productive policies. The state must also be present in realizing justice amid society.
Many parts of the Calotropis gigantea plant are known to contain bioactive compounds, but leaves contain the most. This study aimed to determine the toxicity and antifeedant activity of C. gigantea leaves against Plutella xylostella. The study was carried out from November 2019 to July 2020. Toxicity was tested using the leaf dipping and spraying methods. Antifeedant activity was tested using a no-choice test and a choice test. Identification of the compound composition of the leaf extract of C. gigantea was carried out at the Integrated Research and Testing Laboratory, Gadjah Mada University. Extract toxicity data obtained were analyzed by Probit analysis. The results showed that the antifeedant activity of C. gigantea leaf extract a no-choice and with choice at each concentration had a significant effect on the consumption of P. xylostella larvae rations. The toxicity (LC50) of the leaf extract of C. gigantea to P. xylostella by the dipping method was 2,958 µgl-1 while the spraying application was 3.944 µgl-1. The composition of chemical compounds contained in the leaf extract of C. gigantea is saponins, alkaloids, flavonoids, tannins, phenols, terpenoids. With the composition of these chemical compounds, the leaf extract of C. gigantea has the potential as a source of vegetable insecticide compounds against P. xylostella.

Proses pembelajaran biologi diharapankan mampu memenuhi peraturan pemerintah yang tertuang dalam “Standar Nasional Pendidikan” (SNP) serta mampu mencapai “Standar Kompetensi Lulusan” (SKL). Cara yang dapat dilakukan dalam menciptakan proses pembelajaran sesuai peraturan yang berlaku adalah menggunakan media ular tangga bercerita materi ekosistem yang diharaoakn mampu meningkatkan kemamouan berpikir kritis dan pendidikan karakter. Tujuan penelitian ini adalah untuk mengetahui karakterisik, tingkat kelayakan, dan efektivitas dari media yang dikembangkan. Model pengembangan yang digunakan adalah ADDIE. Teknik pengumpulan data melalui observasi, wawancara tidak terstruktrur, angket, dan tes soal uraian kemampun berpikir kritis. Sampel ujicoba produk skala besar produk ini diujikan secara kuasi eksperimen yakni pada kelas X MIA 1 (eksperimen) dan X MIA 2 (kontrol). Spesifikasi media yang dikembangkan diantaranya: papan ular tangga bercerita, kartu soal, kartu kunci, petunjuk permainan, buku pegangan, dan kotak penyimpanan. Media dilengkapi penanaman nilai karakter serta pertanyaan yang memicu kemampuan berpikir kritis. Hasil kelayakan produk dari ahli materi, ahli media, dan praktisi menunjukkan produk tergolong dalam kategori sangat layak digunakan. Hasil respon siswa juga menunjukkan bahwa media termasuk kategori sangat menarik. Keefektivan media pembelajaran ular tangga bercerita berbasis pendidikan karakter diperoleh rata-rata kelas ekperimen 74.2 sedangkan rata-rata kelas kontrol 66.07 dengan nilai t<sub>hitung</sub>= 3.891 dan t<sub>tabel</sub>=2.0154, sehingga t<sub>hitung</sub> > t<sub>tabel</sub> dan H<sub>a </sub>diterima dan H<sub>o</sub> di tolak, disimpulkan terdapat perbedaan hasil <em>post-test</em> kelas ekperimen dengan kelas kontrol. Uji N-gain didapatkan nilai rata-rata kelas kontrol 35.32 yang berarti sedang dan nilai rata-rata kelas eksperimen 43.48 yang berarti sedang, sehingga disimpulkan bahwa penggunaan media ular tangga bercerita berbasis pendidikan karakter terbukti efektif untuk meningkatkan kemampuan berpikir kritis siswa kelas X pada materi ekosistem MA Hidayatul Mubtadi’in
