Abstract

Landslide Vulnerability Inventory with Landsat 8 OLI TIRS Imagery on the Eastern Slope of Mount Agung. Landslides are one of the natural disasters that often occur in Indonesia and cause loss of life, property, and damage to facilities and infrastructure. Landslide vulnerability on the eastern slope of Mount Agung is categorized as medium to high, making the area very vulnerable to landslides, therefore an inventory of landslide vulnerability in the area is needed. This study aims to analyze the results of land cover interpretation using BSI vegetation index approach and supervised classification on the eastern slope of Mount Agung, Bali, compare the results of land cover accuracy test of BSI vegetation index approach interpretation and supervised classification, and analyze landslide vulnerability from 2013 to 2022. The method used in this research is qualitative by utilizing data taken from Landsat 8 OLI TIRS images recorded from 2013 to 2022 in the form of Blue band, Red band, Near Infrared band, and Shortwave Infrared 2 band. Land cover classification uses Bare Soil Index vegetation index analysis and supervised classification. The results showed that the comparison of the area of non-vegetated land distribution for each year of the Bare Soil Index analysis results was greater than the results of the analysis using supervised classification. The highest non-vegetated land area based on the results of the Bare Soil Index was in 2019 with an area of 11,469.60 ha, while the supervised classification occurred in 2017 with an area of 6,182.03 ha. The accuracy test results show that the BSI method is more accurate (82.86%) compared to the supervised classification method (62.86%). Non-vegetated land (vacant land) based on BSI that is included in the Movement Vulnerability Zone is an area vulnerable to landslides, its distribution changes due to various events that occur in the area such as forest fires, landslides, land use change, and others. The highest vulnerability area was in 2019 amounting to 1,779.03 ha while the lowest vulnerability area was in 2016 amounting to 1028.94 ha.

Abstract

Ginger (Zingiber officinale) is the main biopharmaceutical export commodity of Indonesia. However, its productivity and quality are low because it is not cultivated using optimal techniques. This study aimed to examine the effect of magnesium (Mg) fertilizer on the growth, rhizome yield, and essential oil content of two ginger varieties in the organic field. The two factors tested were the rate of Mg fertilizer application (0, 50, 100, and 150 kg MgOha-1) and the variety of ginger (elephant ginger [Zingiber officinale var. officinarum] and red ginger [Zingiber officinale var. rubrum]). The variables measured were plant height, number of leaves, number of tillers, rhizome weight, and essential oil content. Mg fertilizer application rate and ginger variety significantly affected growth, yield, and essential oil content. No interaction effects were found between the two factors. Mg fertilizer applied at 150 kg MgOha-1 resulted in the highest rhizome yield and essential oil content, with an increase of 21.74% and 15.38%, respectively, compared to the control (0 kg MgOha-1). The yield of elephant ginger was 29.41% higher than that of red ginger, whereas the essential oil content of the red ginger was 16.67% higher than that of the elephant ginger.

Abstract

Rayap kayu kering (Cryptotermes spp.) merupakan hama perusak kayu yang menyebabkan kerugian ekonomi signifikan, dan penggunaan pestisida kimia konvensional menimbulkan masalah lingkungan dan kesehatan. Inovasi penggunaan biopestisida perlu dilakukan untuk meningkatkan efikasi dan stabilitasnya. Sebuah penelitian dilakukan untuk mengevaluasi pengaruh pemberian biopestisida berbasis ecoenzyme terhadap mortalitas, repelensi, dan daya cegah serangan rayap kayu kering. Biopestisida-ecoenzyme dibuat dengan cara memfermentasi 7 bahan nabati sebanyak 12,5% di dalam ecoenzyme selama 30 hari. Pada uji aplikasi biopestisida dan penentuan LC50, percobaan disusun menurut rancangan acak lengkap dua faktor dengan tiga ulangan. Faktor pertama adalah cara pemberian (uji mortalitas, uji repelensi, dan uji proteksi) dan faktor kedua adalah dosis biopestisida (0, 10, 20, 30, 50, dan 75%). Hasil penelitian menunjukkan bahwa biopestisida-ecoenzyme secara signifikan efektif dalam mengendalikan populasi rayap kayu kering melalui tiga mekanisme utama, yaitu: 1) bio-pestisida mampu menyebabkan kematian pada rayap kayu kering dengan nilai LC50 5,90%; 2) biopestisida mampu mengusir rayap kayu kering dengan nilai LC50 35,77%; 3) biopestisida mampu mencegah serangan rayap kayu kering dengan nilai LC50 56,97%. Dengan demikian biopestisida berbasis ecoenzyme memiliki potensi besar sebagai agen pengendali hama rayap kayu kering yang efektif. Pada uji frekuensi pemberian biopestisida, percobaan disusun menurut rancangan acak lengkap dua faktor dengan tiga ulangan. Faktor pertama adalah dosis biopestisida (0, 6, 36, dan 57%) dan faktor kedua adalah frekuensi pemberian (1, 2, dan 3 minggu sekali). Hasil pengujian frekuensi pemberian biopestisida menunjukkan mortalitas rayap sangat tinggi (lebih dari 80%) dengan aplikasi hanya setiap 3 minggu sekali menggunakan konsentrasi 6%.

Abstract

Community empowerment activities aimed at enhancing the knowledge and skills of the community in managing and processing household organic waste have been conducted in Notoprajan Village, Yogyakarta City. The target of this activity is the PKK members and community groups in the village. The activity was conducted using extension and education methods on waste management, which included waste reduction and handling, followed by practical training on processing organic waste. Through this activity, products have been produced in the form of Ecoenzyme scrub, used cooking oil candles, gkalranulated compost, pasteurized liquid organic fertilizer, tutorial videos, and publications in national journals. It is concluded that this training activity can enhance the knowledge and skills of the residents of Kalurahan Notoprajan in managing and processing organic waste. The impact of the success of this activity is contributing to the direct reduction of organic waste volume, minimizing methane (CH4) production and other greenhouse gas emissions, supporting climate change mitigation efforts at the community level, providing practical skills that can open new economic opportunities for the community, transforming waste into sellable products, and enhancing financial independence, as well as improving climate resilience through increased environmental awareness, independence, and active community participation in maintaining the cleanliness and health of their own environment

Abstract

Sampah merupakan sektor penyumbang emisi gas rumah kaca (GRK) di Indonesia. Kabupaten Bantul di Daerah Istimewa Yogyakarta berpotensi besar menyumbangkan emisi gas rumah kaca dari sampah yang berasal dari sektor rumah tangga, pertanian, peternakan, dan wisata. Dari jumlah rata-rata sampah yang mencapai hampir 500 ton per hari, lebih dari 50 % adalah sampah organik. Timbunan sampah organik di tempat-tempat pembuangan sampah mengalami dekomposisi anaerobik, dan proses ini menghasilkan gas metana, yang merupakan GRK sangat kuat. Selain metana, GRK yang potensial dihasilkan dari sampah adalah CO₂ yang berasal dari dekomposisi aerobik, pembakaran sampah, transportasi dan pengolahan sampah pada fasilitas pengolahan sampah bermesin yang menggunakan bahan bakar fosil. Pengelolaan sampah yang baik dan berkelanjutan, seperti pengurangan sampah dari sumbernya, pemilahan, daur ulang, pengomposan, dan teknologi pengolahan sampah yang menghasilkan energi dengan emisi rendah, sangat penting dalam upaya pencegahan (mitigasi) pemanasan global dan perubahan iklim. Kegiatan yang ditujukan untuk meningkatkan pengetahuan dan ketrampilan masyarakat dalam mengelola sampah perlu terus dilakukan, termasuk yang dilaksanakan di Kalurahan Parangtritis. Sasaran kegiatan ini adalah kelompok tani dan peternak, termasuk juga kelompok masyarakat yang bekerja di kawasan wisata pantai di Parangtritis. Kegiatan dilaksanakan menggunakan metode sosialisasi (ceramah) tentang pengelolaan sampah yang mencakup pengurangan dan penanganan sampah, dilanjutkan dengan pelatihan ketrampilan mengolah berbagai sampah organik. Melalui kegiatan ini dihasilkan produk (pupuk organik cair, kompos, decomposer, eco enzyme), video pengolahan, dan publikasi pada jurnal nasional. Disimpulkan bahwa kegiatan pelatihan ini dapat meningkatkan pengetahuan dan ketrampilan warga masyarakat Kalurahan Parangtritis dalam mengelola dan mengolah sampah organik.
