ABSTRACT The conventional management of internship logbooks at the Central Bureau of Statistics (BPS) of Riau Province, which previously lacked standardized formats and clear regulations, resulted in inconsistent record-keeping, low intern discipline, and difficulties in monitoring and evaluation by supervisors. To address these issues, a web-based internship logbook management application was…
Phosphate-Solubilizing Bacteria (PSB) are decomposer bacteria capable of dissolving simple carbon compounds such as root exudates and plant littter. They are part of the rhizobacteria group that can promote plant growth by solubilizing phosphate sources. PSB play a crucial role in increasing the availability of phosphorus in a soluble form for plants. This study aimed to isolate PSB from rhizos…
Bananas are one of the horticultural fruit products widely cultivated in Indonesia. The country has several local banana varieties, including Kepok, Raja, and Awak, which are susceptible to Fusarium wilt. Fusarium wilt affects more than 70% of local banana varieties. This pathogen significantly reduces the productivity of local banana plants and causes the death of more than 35% of banana crops…
Gonystylus bancanus (Miq.) Kurz (ramin) is an endemic tree species of tropical peat swamp forests and is currently classified as critically endangered species. Disease resistant genes such as genes encoding NBS-LRR protein are important to maintain the existence of the species. This study aimed to analyze the NBS-LRR gene sequence in ramin growing in the production forest of PT Diamond Raya Tim…
Acrylamide is a toxic compound that is formed in foods heated above 120°C and can trigger oxidative stress that disrupts the body's metabolism. This study aims to determine the effect of acrylamide administration on cholesterol and uric acid levels in Wistar white rats. The study used 16 male rats which were divided into four treatments: P0 (control), P1 (2.5 µg/kg BW), P2 (5 µg/kg BW), and …
The Arecaceae family, also known as the palm family, is one of the oldest families among flowering plants (Angiosperms). It comprises approximately 200 genera worldwide, with about 25% or around 35 genera and 460 species found in Indonesia.
