    Still limited learning resources available in the library and the inability of most college students to purchase learning resources either in the form of a book or module.Then the necessity created a learning resource in the form of learning materials in the form of modules. This research aims to look at the results of a study of college students in learning using a module-based constructivism. The research is the research action class (PTK) consisting of three cycles, each cycle consists of four stages, namely action planning, implementation, observation, evaluation and reflection. The subject of this study is a three-semester student physical education PGMIPAU. The object of this research is the result of student learning. From the results of the studyobtained the use of Constructivism-based modern physics module on cycle 1 median – median test results of students are 50.54, on average cycle 2 – align students ' test results was 61.00, and median – median 3 cycle test results of students are 66.00, so it can be concluded that the use of Constructivism-based modern physics modules can improve student learning outcomes

    Pengukuran tahanan jenis dengan konfigurasi Schlumberger telah dilakukan di daerah panas bumi Pincara dengan cara mapping dan sounding. Secara geologi, hasil pengamatan geologi lapangan batuan didaerah penelitian didominasi oleh batuan granit dan granodiorit (batuan granitik), batuan lava, batuan breksi, batuan sedimen dan satuan batuan aluvium yang menempati bagian selatan daerah penelitian.. Pengukuran mapping pada bentangan arus AB/2 = 250m, 500m, 750m, dan memperlihatkan daerah bertahanan jenis rendah makin meluas dengan bertambahnya kedalaman ke arah tenggara dengan kontras tidak terlalu besar. Sedangkan anomali bertahanan jenis tinggi cenderung melebar kebagian baratlaut. Secara geologi daerah bertahanan jenis rendah ditafsirkan sebagai batuan sedimen cenderung lebih tebal kearah tenggara, sedangkan batuan yang bertahana jenis tinggi ditafsirkan sebagai batuan beku berupa granit yang tersebar dibagian baratlaut. Kondisi ini mencerminkan makin kearah tenggara batuan sedimen makin dalam dan secara tidak langsung mengindikasikan keberadaan reservoir.Pengukuran Sounding menunjukkan lintasan penampang tahanan jenis semu terdapat perbedaan nilai resistivity yang sangat mencolok pada bagian baratlaut dan tenggara, diduga akibat adanya perbedaan lithologi antara batuan resistif (granit) di bagian baratlaut dengan batuan yang kurang resistif di bagian tenggara (batuan rombakan)

    Get PDF
    Nypa fruticans Wurmb or ‘nipa’ is a palm plant that includes mangrove commodities, found along the mouths of tropical and subtropical rivers. Nipah forests in Indonesia are spread on the coast of the islands of Sumatra, Kalimantan, Sulawesi, Maluku, and Papua. Coastal communities in Indonesia usually use nipah as an ingredient in traditional medicine, food coloring, to various handicrafts. The main phytochemical composition of nipah is polyphenols, phenolics, alkaloids, tannins, flavonoids, and saponins. Therefore, the knowledge and utilization of this nipah plant need to be sought and studied more deeply to optimize its utilization. This study aims to find out the utilization of the phytochemical composition of nipah leaf extract on the coast of Indonesia. The results of the literature study on the phytochemical content of nipa leaves and their use have the potential as traditional medicine, and can act as antioxidants, antidiabetics, antimicrobials (antifungals and antibacterials), anticancer, anti-inflammatory, and analgesic. In addition to medicine, nipah plants are also used as roofs, livestock pens, or huts in gardens, brooms, handicrafts, fishing gear, as food coloring, as a source of food and beverages, to renewable energy fuel sources

    Resistensi Lalat Rumah, Musca Domestica Linnaeus (Diptera: Muscidae) Dari Empat Kota Di Indonesia Terhadap Permetrin Dan Propoksur

    House flies (Musca domestica Linnaeus) is one of the common urban pests causing health, economics, and aesthetics problems. Although intensive control by using inseticides are carried out, there are reports of control failures, which are probably due to insect resistance. Bioassay tests with topical application to study the status as well as resistance mechanism of house flies collected from the city of Jakarta (JKT), Bandung (BDG), Yogyakarta (YGY) and Surabaya (SBY) to pyrethroid (permethrin) and carbamate (propoxur) insecticides were carried out. The results show that, as compared to the most susceptible strain (YGY), we found that BDG strain is highly resistant to permethrin with resistance ratio (RR) of 133.7 fold. SBY strain was the most resistant to propoxur with RR of 38.36 fold, followed by Bandung strain with RR of 18.22 fold. The addition of piperonyl butoxide (PBO) to either permethrin or propoxur in most of the strains caused a decrease in LD50 values and increasing the synergist ratio (SR) suggesting that the detoxifying enzyme mixed function oxidase (MFO) played an important role in the development of resistance to permethrin and propoxur. Our study is the first report of M. domestica resistance to permethrin and propoxur in Indonesia

    Penelitian ini dilakukan untuk menganalisis pembelajaran IPA dengan lesson study berbasis Transcript Based Lesson Analysis (TBLA) dianalisis melalui perekaman dialog pembicaraan guru dan siswa serta pengamatan yang dilakukan oleh observer, penelitian ini berfokus untuk melihat respond siswa selama pembelajaran. Melalui analisis ini dapat dilihat bagaimana penerapan lesson study berbasis Transcript Based Lesson Analysis (TBLA), bagaimana analisis proses pembelajaran bersifat student centered atau bersifat teacher centered dapat dilihat melalui pola dialog yang muncul berdasarkan pembicaraan antar guru dan siswa. Jenis penelitian ini adalah studi kasus, Data dalam penelitian ini berbentuk data penelitian kualitatif. Subjek dalam penelitian ini adalah siswa kelas VIII.4 SMP Al-Falah Kota Jambi. Pengumpulan data dalam penelitian ini menggunakan rekam video selama pembelajaran, catatan lapangan observasi, dan dokumen yang lainnya. Penelitian ini berlansung dalam 2 siklus dilaksanakan pada bulan februari 2021 dengan 3 tahapan Lesson study yaitu plan, do, dan see. Berdasarkan dialog percakapan antara guru model dan siswa pada siklus I dan II ditunjukkan dalam dua grafik number of words. Siklus I dalam penelitian ini terlihat guru masih mendominasi percakapan, tidak banyak siswa yang memberikan respond dan menjawab pertanyaan yang diajukan guru model. Pada siklus II pembelajran berlansung secara diskusi kelompok terlihat beberapa siswa yang aktif berdiskusi dalam memecahkan masalah yang disajikan oleh guru model, dilihat dari banyaknya percakapan yang muncul dalam grafik number of wold siklus II. Saran yang termuat dalam penelitian ini agar guru bisa menerapkan pembelajaran dengan lesson study berbasis Transcript Based Lesson Analysis (TBLA), dengan demikian dapat membantu guru dalam menganalisis proses pembelajaran yang berlansung pada setiap siswa yang dilihat dari dialog percakapan guru dan sisw

    Ubi jalar mengandung beberapa jenis oligosakarida yang mungkin berfungsi sebagai prebiotik, dan diharapkan setelah proses pengolahan, fungsi daari prebiotik dapat dipertahankan. Penelitian ini dilakukan dengan tujuan untuk melakukan uji in vitro dan in vivo ekstrak ubi jalar sebagai prebiotik. Pengujian efektifitas sari ubi jalar terhadap pertumbuhan Bakteri asam laktat dilakukan menggunakan media de Mann Rogosa sharpe broth (MRSB), dengan perlakuan K (-): MRSB sebagai kontrol negatif; K (+) : MRSB + BAL sebagai kontrol positif ; P1 : MRSB + BAL + sari ubi jalar Sukuh ; P2 : MRSB + BAL + ari ubi jalar Betta-1 dan P3: MRSB+ BAL + sar ubi jalar Antin. Pengujian in vivo dilakukan dengan menguji pertumbuhan bakteri asam laktat (BAL) dan uji kompetisi pertumbuhan BAL dan Escheria coli (E.Coli) terhadap ekstrak ubi jalar yang terbaik dari hasil uji in vitro sebelumnya. Uji in vivo dilakukan dengan menggunakan 4 kelompok tikus percobaan, yang masing-masing terdiri dari 4 ekor tikus putih jantan galur Sprague-dawley berumur dua bulan. Berdasarkan hasil uji vitro menunjukkan ekstrak ubi jalar semua varietas memiliki nilai absorbansi yang semakin tinggi pada 0 dan 24 jam dengan panjang gelombang 660 nm. Hal tersebut menunjukkan ekstrak ubi jalar pada dapat menstimulir pertumbuhan BAL dengan baik. Ekstrak ubi jalar dapat menekan pertumbuhan E. Coli dan Menstimulir BAL terutama ubi jalar varietas Betta-1 dan Sukuh. Hasil uji in vivo menunjukkan ekstak ubi jalar pada dosis pemberian ekstrak ubi jalar 0,54 g/hari dan 1,08 g/hari belum efektif meningkatkan bekteri asam laktat fekal dan menekan pertumbuhan bakteri asam laktat E.
