Abstract

Survey of road damage data can be conducted by the direct survey method or manual inspection, but that mothod is quite long and requires a lot of employers, so it is not effective and efficient. This research focuses on the inspection of road damage using drone technology by taking aerial photos using the UAV-Photogrammetry method. Aerial photography was carried out along the roads in the study area. The partial aerial photos are processed using image processing software to become the orthophoto map and digital elevation model (DEM). Road damage data identification was carried out by measuring the dimensions (length, width, and depth) from the orthophoto map and DEM by the visual interpretation method. The research results show that the types of road damage identified from the orthophoto map and DEM in the study area are potholes, block cracks, continuous cracks, and patches. The accuracy of the dimensions of road damage produced from the orthophoto map and DEM compared to the dimensions of road damage measured directly has different values for horizontal of 0.001 - 0.088 m and vertical of 0.010 - 0.019 m, RMSE values range from 0.005 to 0.058. The results of the t-test statistical test show that there is no significant difference between measurements of road damage dimensions from the orthophoto map and DEM and the results of direct measurements.

Abstract

Kegiatan penghijauan pada area pemukiman kini semakin giat dilakukan agar mendapatkan lingkungan yang hijau, sehat dan asri. Pelestarian lingkungan dengan cara menanam tumbuhan dan pohon menciptakan udara bersih dan sehat serta mendapatkan penyerapan air yang baik di lingkungan terutama di area pemukiman. Pada tumbuhan memiliki suatu bagian yang tumbuh pda ranting atau batang dan biasanya tumbuh berhelai-helai hingga lebat yang biasa disebut dengan daun. Daun memiliki banyak warna yang bervariasi, namun kebanyakan memiliki warna hijau dikarenakan didalam daun tersebut terdapat zat klorofil. Adapun warna daun selain berwarna hijau disebabkan karena zat klorofil pada daun tersebut tidak terlalu banyak. Selain fungsi utama daun sebagai tempat fotosintesis dan pengahasil oksigen, daun dapat digunakan sebagai pewarna alami pada kain atau tekstil. Salah salu teknik pemanfaatan daun tumbuhan sebagai alternative pewarna alami pada tekstil adalah teknik ecoprint. Teknik ecoprint merupakan suatu proses pewarnaan dengan mentransfer warna pada daun ke kain melalui kontak langsung. Teknik ini dianggap lebih mudah dan lebih efisien sehingga dapat dilakukan tanpa perlu keahlian khusus. Dengan adanya penyuluhan pemanfaatan daun tumbuhan sebagai alternative pewarna alami diharapkan dapat menciptakan kreativitas masyarakat dan menjadikan peluang usaha dengan nilai jual tinggi.

Abstract

The construction industry is globally recognized for its high occupational risks, making the implementation of robust Occupational Safety and Health (OSH) programs a critical concern. While the importance of OSH is undisputed, its direct, quantifiable impact on worker performance requires continuous empirical validation. This study aims to analyze the influence of occupational safety and occupational health practices on the performance of workers in a high-rise building project in Surabaya, Indonesia. Utilizing a quantitative approach, data were collected from 63 project personnel via a structured questionnaire. The data were analyzed using multiple linear regression. The results confirm a significant and positive relationship, with OSH practices collectively explaining 44.2% of the variance in worker performance (Adjusted R² = 0.442). A partial analysis of the regression coefficients revealed that occupational safety (β = 0.453) exerts a more dominant influence on performance than occupational health (β = 0.341). This study provides quantitative evidence that OSH programs are not merely a compliance requirement but a direct investment in operational productivity, with tangible safety measures being the primary driver of enhanced worker performance.
