This study aims to determine the effect of busy book media on the fine motor skills of children aged 4–5 years at Bina Cakrawala Kindergarten PALI. The method used is quantitative with a one-group pretest-posttest design, and the sampling technique uses purposive sampling with a total of 10 children. Data collection techniques use performance test sheets to measure children's fine motor skill…
Thrombosis is the leading cause of morbidity and mortality due to cardiovascular disease, thus requiring the development of more effective and safer thrombolytic therapies. This study aims to optimise the biosynthesis of silver nanoparticles (AgNP) based on green synthesis using leaf and stem extracts of gambir (Uncaria gambir) as biocompatible photothermal thrombolytic agents. Optimisation was…
Nitrate transport in subsurface tidal swamp land was evaluated using fieldmeasured hydraulic conductivity and numerical modeling. The study was conducted in Mulya Sari, Banyuasin, employing the auger hole method, laboratory analysis, and MODFLOW-MT3DMS simulation. Hydraulic conductivity ranged from 46.44 to 323.87 cm/day (average 185.66 cm/day), indicating high values, while nitrate concentrati…
The increasing production of coal fly ash waste in Indonesia and its relatively low utilization rate, highlighting the need for effective treatment methods to enhance its added value. The objective of this research was to investigate the effect of the Sequential Acid–Alkaline Leaching (SAAL) method on the chemical composition of coal fly ash (CFA) using X-Ray Fluorescence (XRF) analysis. Coal…
This study aims to analyze the reinforcement efficiency of pilecap beams and floor slabs subjected to variations in pump-induced vibration loads in the Karanganyar Pulokerto Pump Intake Structure. The analysis was carried out using ETABS software with the Walking Vibration Analysis method on two types of centrifugal pumps, namely EN 733 and DPV 18-60. The evaluation was based on vertical accele…
Sustainable agricultural development is an important part in achieving the Sustainable Development Goals (SDGs), especially goal 3 (Good Health and Well Being), goal 8 (Decent Work and Economic Growth), and goal 15 (Terrestrial Ecosystems). Pemulutan District as a swamp area in Ogan Ilir Regency has a large potential for rice production, but still faces various drought challenges such as limite…
Sistem pengelolaan inventarisasi data aset pada Dinas Kelautan dan Perikanan Provinsi Sumatera Selatan saat ini belum terintegrasi secara optimal. Seluruh data inventaris yang tergabung menjadi satu kesatuan besar tanpa kategorisasi yang sistematis menyulitkan proses pemantauan kondisi kelayakan barang, pelacakan riwayat perawatan, serta penyusunan laporan periodik. Penelitian ini bertujuan unt…
Student attendance is an important activity in supporting school administration and monitoring student presence. SMP Negeri 30 Palembang still uses a manual attendance system that is less effective. The recording and recapitulation processes take time and are prone to errors This study aims to design and implement a web-based student attendance application, The system uses barcode technology to…
Peat soil is formed from the accumulation of organic matter, resulting in a high carbon content and high acidity. Although peat soils generally have a high cation exchange capacity (ECC), the availability of basic nutrients, such as potassium (K), is often low. This study aimed to determine the ECC value and K availability in peat soils of oil palm plantations during the TBM and TM phases at PT…
