Abstract

Eucalyptus is one of the fast growing species plants, currently used in the pulp and paper industry. The leaves of Eucalyptus are known as forest harvesting waste. This research aim to examine the antibacterial potency and the physicochemical profiles of Eucalyptus pellita leaves waste essential oils grown in PT Surya Hutani Jaya Site 32, East Kalimantan named EP B077. The essential oils distilled using water and steam distillation methods. Analysis of physicochemical profiles from this oil included yield, colour, refractive index, specific gravity, and chemical compositions by GC-MS. Antibacterial activity assayed by agar diffusion method against Staphylococcus epidermidis, Streptoccoccus sobrinus and Streptoccoccus mutans with slight modification. The results showed that EP B077 had the yellow colour, yield oils was 0.44%, 1.471 of refractive index, and 0.8706 of specific gravity. Chemical components of EP B077 oils were dominated by α-Pinene (40.36%), 1-β-Pinene (31.75%), Cyclohexene, 1-methyl-4-(1-methylethenyl)- (9.64%), Trans(β)-Caryophyllene (4.29%) and Eucalyptol (1,8-Cineole) (3.88%). This EP B077 oils was active to inhibit bacteria against S. epidermidis and S. sobrinus range from 9-15 mm, also against S.mutans ranging from 9-14 mm. Based on the results, this Eucalyptus pellita leaves named EP B077 had potential to develop as a new source of essential oil and antibacterial agents.

Abstract

Plant use as traditional medicine is still widely practiced in Indonesia. Muara Tae tribe people, West Kutai regency are one of the regions that still rely on Blumea balsamifera and Cordyline fruticosa plants as traditional medicine. This study aims to determine the potential of Blumea balsamifera and Cordyline fruticosa leaves as medicinal plants with phytochemicals and antioxidants. Phytochemical analysis was tested using Harborne and Kokate methods. Antioxidant activity was evaluated by DPPH radical scavenging assay with slight modification. The results of the phytochemical analysis showed that the extracts of n-hexane, ethyl acetate, and ethanol from the leaves of Blumea balsamifera and Cordyline fruticosa contained alkaloids, tannins, and triterpenoids. Antioxidant activity of Blumea balsamifera leaves extract showed that the n-hexane extract display an ability to inhibit DPPH free radical by 50% at 100 ppm concentration, while ethyl acetate and ethanol extracts display an ability by 77% and 81% at 50 ppm concentration. IC50 value of ethyl acetate and ethanol extracts of Blumea balsamifera leaves sequentially were 23.68 µg/mL and 17.59 µg/mL. Antioxidant activity of Cordyline fruticosa leaves extract showed that the n-hexane and ethyl acetate extract display an ability to inhibit DPPH free radical by 45% and 56% at 100 ppm concentration, while ethanol extracts display an ability by 76% at 50 ppm concentration. IC50 value of ethyl acetate and ethanol extracts of Cordyline fruticosa leaves sequentially were 73.72 µg/mL and 20.17 µg/mL. Based on the results, Blumea balsamifera and Cordyline fruticosa leaves extracts had the potential to develop as natural antioxidants.

Abstract

Salah satu aspek penting dari pembangunan berkelanjutan adalah partisipasi masyarakat lokal yang mengikuti. Di daerah perkotaan, partisipasi seperti itu diperlukan dalam konservasi hutan mangrove untuk mendukung pengembangan daerah pesisir. Penelitian ini bertujuan untuk menjelaskan upaya konservasi yang dilakukan hutan bakau oleh masyarakat lokal yang berada di daerah perkotaan. Metode yang digunakan adalah studi kasus, di mana pengumpulan data dilakukan melalui wawancara mendalam dan observasi partisipan. Hasil penelitian menunjukkan bahwa masyarakat menerapkan  pengetahuan  ekologi traisional dan  mendirikan  institusi  sehingga  pelestarian  mangrove tetap  terjaga. Pemerintah kota dan perusahaan lokal juga memainkan peran dengan mendukung upaya-upaya dibuat oleh komunitas lokal

Abstract

Perubahan iklim menjadi permasalahan global yang berdampak pada kehidupan di muka bumi dimana untuk pengendaliannya memerlukan intervensi dari semua pihak. Perempuan memiliki peran strategis dalam memitigasi perubahan iklim melalui kegiatan domestik rumah tangga. Hanya saja dalam konteks lingkungan tidak banyak perempuan yang menyadari dan paham akan posisi dan perannya. Oleh karenanya diperlukan sosialisasi dan edukasi gaya hidup yang mendukung keberpihakan kepada lingkungan. Kelompok sasaran sosialisasi dan edukasi adalah perempuan anggota Dasawisma Alamanda Kelurahan Sidodadi Samarinda Kota. Metode yang digunakan adalah presentasi, tanya jawab dan diskusi serta pemutaran video-video pendek yang relevan dengan perempuan dan perubahan iklim. Perempuan merupakan agent perubahan yang memiliki peran strategis dalam penyelamatan lingkungan melalui aksi-aksi kecil dan nyata dari lingkup domestik rumah tangga. Hemat dalam menggunakan energi, bijak memanfaatkan air, cerdas memilih peralatan rumah tangga dan terampil dalam memilah dan mengolah sampah merupakan perilaku yang berpihak terhadap lingkungan. Disiplin mempraktikkan sikap dan perilaku yang mencerminkan cinta lingkungan dalam rumah tangga akan menular kepada anggota keluarga lain dan lingkungan sekitar. Pada gilirannya akan menjadi green lifestyle yang berkontribusi positif terhadap perbaikan lingkungan. Kata Kunci: Perempuan, Perubahan Iklim, Mitigasi, Green Lifestyle
