Abstract

Bunga Kembang Sepatu (Hibiscus rosa-sinensis L) berpotensial sebagai salah satu sumber antosianin yang dapat berfungsi sebagai antioksidan, antimutagenik, dan antikarsinogenik. Antosianin dapat rusak pada suhu tinggi (pemanasan) yang biasa digunakan dalam pembuatan sejumlah produk pangan. Penelitian ini bertujuan untuk mengkaji kandungan antosianin dalam bunga kembang sepatu berdasarkan variable konsentrasi pelarut. Penelitian dilakukan dengan metode ekstraksi maserasi menggunakan pelarut etanol konsentrat dalam air. Variable tetap yang digunakan dalam penelitian ini adalah konsentrasi etanol (60, 70, 80, 90, 96 % (v/v)). Waktu maserasi adalah selama 24 jam pada temperatur ruang dan kondisi terlindung dari cahaya matahari ataupun sinar langsung. Hasil ektraksi kemudian disaring dan dipekatkan dengan rotary vakum evaporator dan selanjutnya dianalisis menggunakan instrument Spektrofotometer  UV-Visible. Hasil penelitian menunjukkan bahwa rendemen dan kadar antosianin tertinggi ditandai dengan warna yang paling pekat yang didapatkan dari pelarut ethanol 96%. Hasil rendemen tertinggi yang diperoleh adalah 22,05% (b/b) yang mengandung ekstrak antosianin sebesar 48,260 mg dari 25 gram bahan baku. Persamaan yang menghubungkan antara variable konsentrasi pelarut etanol dan rendemen adalah y = -36,547x2 + 72,335x + 12,422. R2= 0,9642.Kata kunci : antosianin,ekstraksi, Hibiscus rosa-sinensis L, kembang sepatu

Abstract

Penelitian ini berangkat dari permasalahan dalam proses pembelajaran dan hasil belajar yang terjadi di kelas VIII A SMP Negeri 2 Gedangsari pada mata pelajaran PPKn. Proses pembelajaran tidak kondusif (siswa tidak fokus, berbicara dengan teman selama pembelajaran, tidak memerhatikan penjelasan guru). Prestasi belajar yang diperoleh siswa cenderung rendah (rata-rata 71,94 dari KKM 75). Selain itu, dari 34 siswa, hanya 10 orang siswa yang memenuhi ktiteria KKM. Bertolak dari permasalahan tersebut, tujuan penelitian ini adalah untuk meningkatkan motivasi belajar siswa yang diharapkan akan berdampak pada peningkatan prestasi belajar siswa. Upaya ini dilakukan dengan cara mengganti model pembelajaran yang konvensional dengan pembelajaran yang inovatif, yaitu pembelajaran kooperatif tipe Group Investigation. Jenis penelitian ini termasuk Penelitian Tindakan Kelas yang menggunakan model Kemmis dan Taggart. Pengumpulan data dilakukan dengan teknik tes (untuk prestasi belajar), dan pedoman observasi (untuk motivasi belajar). Data yang terkumpul dianalisis dengan teknik analisis deskriptif. Hasil penelitian menunjukkan terjadi peningkatan motivasi belajar dari pra siklus ke siklus I dan siklus II. Rata-rata motivasi belajar siswa meningkat menjadi 32 pada siklus I, dan meningkat lagi menjadi 41 pada siklus II. Sedangkan prestasi belajar juga senantiasa mengalami peningkatan. Pada siklus I, rata-rata nilai meningkat menjadi 79,91 dengan ketuntasan sebanyak 26 orang. Sedangkan pada siklus II, rata-rata nilai meningkat menjadi 89,59 dengan ketuntasan sebanyak 32 siswa. Oleh karena itu dapat disimpulkan bahwa penggunaan pembelajaran Group Investigation dapat meningkatkan motivasi belajar dan prestasi belajar siswa pada mata pelajaran PPKn.

Abstract

Udara adalah faktor penting dalam kehidupan, namun, di era modern, sejalan dengan perkembangan pembangunan fisik kota dan pusat industri, serta berkembangnya transportasi, telah menyebabkan kualitas udara mengalami perubahan. Dari yang mulanya segar, kini, kering dan kotor akibat dari terjadinya pencemaran udara karena kendaraan transportasi. Lewat penggunaan metode kepustakaan, maka, tampak dengan jelas ada beberapa hal yang harus mendapatkan perhatian yang serius, di antaranya; 1. Pemberian izin bagi angkutan umum kecil lebih dibatasi, sementara, kendaraan angkutan massal, diperbanyak. 2. Kontrol jumlah kendaraan pribadi. 3. Pembatasan usia kendaraan . 4. Pembangunan MRT, dan pembuatan Electronic Road Pricing. 5. Pengaturan lalu lintas, rambu-rambu, dan tindakan tegas terhadap pelanggaran berkendaraan. 6. Uji emisi harus dilakukan secara berkala pada kendaraan umum maupun pribadi. 7. Penanaman pohon berdaun lebar di pinggir jalan yang lalu lintasnya padat serta di sudut-sudut kota.

Transportation is the backbone in creating social welfare in Jakarta. Therefore, if there are problems in the transportation system, it will have an impact on the smooth traffic flow and will ultimately hamper the achievement of public welfare. This study used a descriptive-qualitative method. This study refers to the theory proposed by Anderson (in Tachjan, 2006: 23) and Sarana, et al (2009: 9). The results of the study are as follows. Policy implementation transportation system in Jakarta has been able to improve the social welfare of most citizens, which means some people have to feel and enjoy the outcome of transportation development  in Jakarta.
