The PIRT permit is a form of legality and guarantee that a processed food product has met quality …
ABSTRACT Sweet corn (Zea mays saccharata Sturt.) is an important horticultural crop valued for its sweetness and nutritional composition. Productivity in Riau Province remains below the national average due to the predominance of marginal soils such as Inceptisols, which are characterized by low pH, low base saturation, and limited nutrient availability. Soil fertility improvement has been att…
ABSTRACT Shallots are a high-value horticultural crop. A major constraint in its cultivation is the limited availability of quality bulb seeds, which are often disease-prone, bulky to transport, and required in large quantities per hectare. Mini bulbs produced from true shallot seed offer an alternative planting material that is healthier, more efficient, and easier to handle during storage an…
ABSTRACT Felling activities in Industrial Forest Plantations (IFP) present occupational safety and health risks due to the use of mechanical tools such as chainsaws and tree shears.

Students and educators must also be able to use technology such as gadgets because learning media will also be more focused on technology such as platforms on gadgets so that learning has variations that can build students' enthusiasm for learning in the learning process. This development research aims to produce E-LKPD based on experiential learning using liveworksheets on acid-base material f…
ABSTRACT Rice husk is an abundant agricultural waste containing lignocellulosic compounds and silica, which have the potential to be used as a base material for adsorbents. This study aims to examine the effect of varying heating temperature and time on the physicochemical characteristics and adsorption capacity of rice husk as an adsorbent. Rice husk was heated at temperatures of 100°C, 125�…
ABSTRACT The contamination of lead (Pb) heavy metal in industrial waste is one of the serious environmental problems that threaten both the environment and human health. Industrial wastewater containing lead ions (Pb²⁺) can accumulate in the food chain, posing a danger to human health. One effective and environmentally friendly solution is the adsorption method using biomass as an adsorbent…

Pemahaman konsep dalam pembelajaran kimia memiliki peran penting dalam membentuk pengetahuan ilmiah yang utuh pada peserta didik. Namun, kenyataannya masih banyak peserta didik yang mengalami miskonsepsi yaitu pemahaman keliru yang bertentangan dengan konsep ilmiah yang sebenarnya. Miskonsepsi ini seringkali terjadi pada materi yang bersifat abstrak seperti struktur atom, di mana peserta didik …
ABSTRACT The fluctuating rainfall pattern in Pekanbaru poses a challenge in determining the optimal planting time for red chili cultivation. Reliance on traditional planting calendars often increases the risk of crop failure since it does not account for climate variability. This study develops a daily rainfall prediction model using the CNN–BiLSTM architecture with BMKG weather data from Ja…
ABSTRACT Tracer studies at the program level often suffer from manual collection, delayed updates, and limited, non-standardized reporting hindering accreditation and curriculum review. This study designs and develops a program-level, web-based tracer study system for the Informatics Engineering Program at Universitas Riau using Laravel 11 and MySQL, with DataTables for interactive data views …
ABSTRACT Linear Alkylbenzene (LAB) is an organic chemical compound in the form of a clear liquid (molecular formula C₆H₅CₙH₂ₙ₊₁, n=C9-C14) which acts as the main raw material in the production of detergents and cleaning products. This compound has the advantages of high biodegradability and better cleaning effectiveness than other surfactants, as well as characteristics that are …
