Abstract

Kendaraan barang yang selama ini diandalkan sebagai alat distribusi barang nampaknya memiliki berbagai permasalahan. Masalah yang muncul adalah akibat dari kelalaian pengguna dengan memberikan beban muatan yang berlebih pada kendaraan tersebut. Berbagai permasalahan yang dapat terjadi karena muatan berlebih pada angkutan barang apabila tidak ditanggapi dengan serius dapat menyebabkan kerugian yang semakin besar. Memanfaatkan teknologi saat ini, dikembangkannya sebuah sistem anti overloading pada kendaraan barang yang dapat mengatasi permasalahan kelebihan muatan. Di dalam perancangan alat ini perlu dilakukan eksperimen awal untuk mencari batas jarak beban aman sebagai dasar membuat program. Metode penelitian yang digunakan pada penelitian ini adalah Research and Development (R&D) yang merupakan suatu proses untuk mengembangkan produk baru atau menyempurnakan produk yang telah ada. Desain pemasangan dari sistem anti overloading pada rangka chasis bawah untuk mendeteksi batas jarak beban aman dan beban muatan antara rangka chasis bawah dengan dumper kendaraan. Kinerja sistem menggunakan sensor jarak pada alat peraga dengan beban yang diberikan dapat bekerja dengan baik serta alat dapat memberikan kinerja output sesuai dengan pemrograman yang telah dirancang seperti menampilkan hasil pembacaan jarak dan beban muatan pada handphone Android. Tingkat akurasi dari fungsi sensor terhadap pembacaan jarak memiliki persentase rata-rata success 100% dan error 0%.

Abstract

One of the most common stresses in rice cultivation is salinity. Rice plants stressed by salinity exhibit changes such as yellowing leaves, drying tips, and chlorosis. The efforts made by the government and farmers so far include implementing cultivation scheduling techniques, planting patterns, and using stress-resistant varieties, as well as improving soil to increase water-holding capacity through lime application. Each of these efforts comes with its own risks. Another approach to enhance the growth and yield of rice plants is the application of vitamins. Providing vitamins can stimulate the growth of plant organs, as they play a crucial role in the growth process by acting as catalysts for metabolism. Research has indicated that vitamin B1 can significantly promote plant growth under stressful conditions. This study aims to investigate the positive effects of various concentrations of vitamin B1 on the growth and yield of rice plants while also reducing salinity stress. The method used involved planting three varieties of rice—IR-46, Inpari-32, and Pokkali—in planting buckets using the TABELA system. Vitamin B1 was applied at concentrations of 0, 5, and 10 mM during the peak vegetative phase, with salinity stress of 6 dS/m introduced one day after vitamin application. The plants were maintained under salinity stress conditions until harvest, during which morphological and phytochemical analyses were conducted. Morphological analysis included measurements of plant height, number of tillers, number of productive tillers, number of grains per panicle, and percentage of healthy grains. Biochemical parameters measured included total chlorophyll and electrolyte leakage analysis. The results indicate that vitamin B1 can effectively reduce stress in plants affected by salinity.

Abstract

Construction productivity plays a crucial role in determining the success and efficiency of project implementation. In foundation works, particularly bored pile installations, productivity is often affected by various technical and environmental factors. This study focuses on analyzing the productivity of bored pile foundation work on the Hotel X project in Lumajang City and identifying the dominant factors that hinder performance. The research employed a mixed-method approach combining quantitative productivity analysis with qualitative field observations and interviews. Productivity data were calculated using the Unit Completed method, while statistical testing was conducted using SPSS software to determine the correlation between influencing variables such as materials, equipment, labor, environment, and management. The analysis revealed that for bored piles with diameters of 600 mm and 500 mm at depths ranging from 5 to 18 meters, the average productivity rate was 0.86 meters per hour per unit during a 37-day observation period (totaling 1,713 working hours). Material factors contributed most significantly to productivity losses, accounting for 39.66% of total lost work hours (165.53 hours out of 417.35 hours), followed by environmental, equipment, labor, and management factors. The findings demonstrate that inadequate material logistics and unstable soil conditions substantially reduce project efficiency. In conclusion, effective management of these key factors is essential to improve productivity performance in bored pile foundation work on construction projects.

Abstract

Climate change in Indonesia has led to an increase in abiotic stress, particularly drought, which significantly affects sugarcane productivity. This research was conducted from 2024 to 2025 at the Laboratory of Molecular Biology and Biotechnology, Waste Management Unit, and Integrated Laboratory, University of Jember. The aim of this study was to evaluate the agronomic, physiological, and biochemical responses of five sugarcane varieties under drought stress conditions. The results showed that drought stress had varying impacts depending on the tolerance of each variety. The drought-tolerant transgenic variety (NXI4T) exhibited more stable responses, as indicated by lower drought and leaf rolling scores, higher soil water content (SWC) and relative water content (RWC), and relatively stable levels of chlorophyll, phenolics, and flavonoids. In addition, lower H₂O₂ accumulation and a stronger root system supported better adaptation to drought conditions.
