Abstract

In visual way, distinguishing mangrove land cover located in Kembung river Bengkalis is hard to do especially if it is using far remote sensing technology. However by applying spectral analyze method, this problem is possibly fixed. It started by taking area sample (training area) 3x3 pixels as many as 10 areas for each classes of land cover, then the result obtained is analyzed by statistical variability test before continued to DMRT test to measure the ability of separation by using separability. Based on the analysis of variability to the spectral value of sattelite vision Sentinel-2A that F-hit (17,626) higher than F-tab (1,98), it showed the treatment has significant effect. The result of DMRT test on reflectancy value of spectral sattelite vision sentinel-2A can be classified into five spectral groups and DMRT test to the mangrove land cover consisted of four groups. Meanwhile, based on separability test there are 36 class pairs, 32 (90,9%) can be separated each way, while 4 (9,1%) can not be separated.

Abstract

Pekerjaan di bidang kehutanan tergolong berisiko tinggi, baik terhadap kecelakaan kerja maupun penyakit akibat kerja. Rendahnya kesadaran pekerja terhadap pentingnya Keselamatan dan Kesehatan Kerja (K3) menjadi salah satu penyebab utama belum optimalnya penerapan K3 di sektor ini. Sayangnya, pemahaman mengenai K3 masih sangat minim, baik dari segi edukasi, pelatihan, maupun sosialisasi di lingkungan kerja kehutanan. Siswa SMK Kehutanan, sebagai calon tenaga kerja masa depan, perlu dibekali sejak dini dengan pengetahuan menyeluruh tentang pentingnya K3. Kegiatan ini bertujuan untuk memberikan informasi dan pemahaman awal kepada siswa, khususnya di SMK Negeri Kehutanan Pekanbaru, agar mereka memiliki kesiapan bekerja secara sehat, aman, dan bertanggung jawab setelah menyelesaikan Pendidikan. Kegiatan diimplementasikan melalui sosialisasi K3 yang mencakup tiga tahapan utama: prasosialisasi, sosialisasi, dan pascasosialisasi. Materi disampaikan melalui metode posko dengan pendekatan edukatif, partisipatif, dan interaktif. Terdapat empat fokus materi yang diberikan, yaitu: (1) K3 di bidang kehutanan, (2) alasan pentingnya K3, (3) alat pelindung diri (APD) yang digunakan dalam kehutanan, dan (4) perancangan praktik kerja kehutanan yang sesuai dengan standar K3. Hasil kegiatan menunjukkan bahwa pendekatan ini efektif dalam meningkatkan pengetahuan siswa. Evaluasi dilakukan melalui pre-test dan post-test terhadap 20 indikator yang telah ditentukan. Hasilnya menunjukkan peningkatan pengetahuan siswa dari 49% sebelum sosialisasi menjadi 82% setelah kegiatan berlangsung. Ini membuktikan bahwa kegiatan sosialisasi berhasil membangun kesadaran awal siswa mengenai pentingnya perlindungan diri dan keselamatan kerja sejak dini, khususnya dalam sektor kehutanan.

Abstract

Soil is an important component of forest ecosystems because it acts as a provider of nutrients, a support for vegetation, and a regulator of biogeochemical cycles. Variations in the physical and chemical properties of soil are greatly influenced by vegetation cover and soil depth. This study aims to analyse the chemical properties of soil in two types of vegetation cover, namely dense and moderate cover, in the Riau University Arboretum, which was determined using the Normalised Difference Vegetation Index (NDVI) method. Soil samples were taken at three depths (0–10 cm, 10–20 cm, and 20–30 cm) to determine the vertical variation in soil chemical properties. The parameters analysed included pH, organic carbon (organic C), total nitrogen (total N), phosphorus (P₂O₅), and potassium (K₂O). The results showed that soil pH was in the acidic category, ranging from 4.43 to 5.21. Organic carbon content was higher in the surface layer than in the lower layers, with the highest value of 5.14% in medium cover. Total N content was low in all samples (0.11–0.25%), indicating a limitation of nitrogen as a factor restricting vegetation growth. The nutrient elements P₂O₅ and K₂O tended to be higher in the surface layer, especially in dense cover (P₂O₅ = 26.66 mg/100 g; K₂O = 24.56 mg/100 g). In general, dense cover was able to maintain nutrient availability better than medium cover, although medium cover had relatively higher organic C content on the surface. These findings confirm that vegetation cover plays an important role in maintaining soil quality, and the preservation of dense vegetation needs to be optimised to support soil fertility and the sustainable conservation function of the arboretum.
