Abstract

Abstrak: Penelitian ini bertujuan mengembangkan perangkat pembelajaran kimia berorientasi model inkuiri terbimbing dengan strategi mind mapping yang valid, praktis dan efektif. Jenis penelitian yang dilakukan adalah penelitian pengembangan dengan model Research Development (R D). Perangkat pembelajaran diujikan terhadap siswa kelas XI SMA Negeri 1 Tuban Tahun Pelajaran 2014/2015 pada materi hidrolisis garam. Hasil penelitian menunjukkan: (1) validitas teoritis terhadap rencana pelaksanaan pembelajaran, buku ajar siswa, lembar kegiatan siswa dan tes hasil belajar berkategori sangat baik; (2) keterlaksanaan rencana pelaksanaan pembelajaran berkategori baik; (3) aktivitas siswa menunjukkan nilai tertinggi pada kegiatan membuat rumusan masalah, membuat hipotesis sementara, mengumpulkan data dan berdiskusi dengan teman; (4) keterbacaan Buku Ajar Siswa (BAS) dan Lembar Kegiatan Siswa (LKS) mudah dipahami oleh siswa (5) seluruh siswa mencapai ketuntasan hasil belajar dengan nilai tinggi (0,9); dan (6) respon siswa baik terhadap proses pembelajaran. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa perangkat pembelajaran kimia SMA menggunakan model inkuri terbimbing dengan strategi mind mapping pada materi hidrolisis garam layak sehingga dapat digunakan dalam pembelajaran.Kata Kunci: inkuiri terbimbing, pengembangan perangkat pembelajaran, strategi mind mapping.

Abstract

Diabetes mellitus is an acute metabolic disorder with several causes with symptoms such as high blood sugar volume accompanied by disorders of carbohydrate, lipid and protein metabolism as a result of insulin function insufficiency. The use of synthetic hypoglycemic chemical drugs can cause some side effects and require relatively expensive costs, so traditional herbal medicine is preferred because it has less side effects and lower costs. Plants that can be used as traditional medicine are secang wood plants (Caesalpinia sappan L). Based on literature studies, compounds contained in the stem or wood part of secang contain flavonoid, tannins, gallic acid, resins, brasilein, α-phellandrene, oscimene, essential oils, resorcinol, and brasilin. It is known that tannic acid (tannins) has antioxidant activity and has an antidiabetic mellitus effects and the brazilin content of secang wood plays a very important role in reducing blood sugar levels. brazilin has three mechanisms of action in reducing blood sugar levels, namely reducing oxidative stress, inhibiting intestinal mucosa GLUT 2, and inhibiting phosphodiesterase. The antihyperglycemic activity of brazilin helps insulin work in the absorption of glucose from the bloodstream into adipose cells by increasing the translocation of glucose transport especially GLUT4. This shows that the extract from the secang wood plant has the potential as an antidiabetic mellitus. Keywords: Antidiabetic mellitus; Antioxidant; Hyperglycemic; Secang wood

Abstract

Artritis reumatoid (AR) is a chronic inflammatory disease caused by inflammatory mediators that migrate to synovial and particular tissues. The disease is characterized by synovial inflammation that leads to the destruction of cartilage and joint damage. Although conventional treatments of AR such as NSAID, corticosteroid and DMARDs commonly alleviate the symptoms of AR, but the high edverse of these treatments leads AR patients toward alternative medicine. The purpose of the present review is to evaluate the potential of secang in rheumatoid arthritis therapy. Various phytochemical components of secang provide pharmacological effects such as antioxidant activity in suppressing oxidative stress as a promoter for disease, including inflammation. Anti-inflammatory and anti-arthritis activities of secang are able to inhibit pro-inflammatory cytokine regulation and cartilage degradation in AR. The pharmacological effect of secang has the potential to be used as a functional food or supplement in the therapy of AR by preventing, treating and repairing the damage caused by AR.. Key words: Anti-arthritis, Anti-infammatory, Anti-oxidant, Artritis Reumatoid, Caesalpinia sappan L.
