Abstract

Metode sonic bloom merupakan pengembangan ilmu pengetahuan dan teknologi di bidang pertanian yang memanfaatkan gelombang suara dengan frekuensi tinggi tanpa merusak lingkungan. Aplikasi sonic bloom berpotensi untuk meningkatkan pertumbuhan pada tanaman yang ditunjukkan dengan adanya peningkatan pembukaan stomata, perkecambahan, pertumbuhan (tinggi tanaman, tinggi dan diameter batang, panjang dan lebar daun, dan panjang akar) serta produktivitas. Metode sonic bloom yang efektif menggunakan bunyi dengan rata-rata intensitas bunyi 65-75 dB, frekuensi bunyi 3-5 kHz dan lama pemaparan 3 jam per hari serta variasi jenis musik.  Gelombang bunyi ini menginduksi pembukaan stomata yang berdampak pada peningkatan penyerapan CO2, H2O dan unsur-unsur hara oleh tanamanThe sonic bloom method is the development of science and technology in agriculture that utilizes high-frequency sound waves without damaging the environment. Sonic bloom application was potential to increase plant growth as indicated by an increase in stomata opening, germination, growth (plant height, height and diameter of stem, length and width of leaf, and root length) and productivity. An effective sonic bloom method used sound with an average sound intensity of 65-75 dB, a sound frequency of 3-5 kHz and an exposure time of 3 hours per day as well as a variety of types of music. This sound wave induced the opening of stomata which had an impact on increasing the absorption of CO2, H2O and nutrients by plants.

Abstract

Public perception of turtle conservation in an area will determine the success of turtle conservation activities. This study aims to analyze the perception of tour guide groups towards turtle conservation on the coast of Bunaken Island, Bunaken National Park, Manado, North Sulawesi. The research method was carried out by means of observation and surveys. Collecting data in the form of interviews with a questionnaire guide. The selection of respondents was carried out by purposive sampling with the target group of tour guides, especially dive guides. Data analysis was carried out using a qualitative descriptive method. The results showed that most of the respondents (78%) already understand about turtle conservation and no longer consume turtles (100%). The turtle habitat which includes coral reefs and seagrasses still supports the presence of turtles and turtles are almost visible at all observation locations. The understanding of turtle conservation by dive guides is quite good, but to maintain the sustainability of conservation so that it is maximized, it is necessary to provide guidance and supervision to the diving guides and also to the surrounding community.
