Abstract

Daun kemangi (Ocimum basilicum) merupakan salah satu dari banyaknya jenis tanaman obat. Daun kemangi terbukti mengandung senyawa aktif saponin, terpenoid, tannin dan flavonoid.  Penelitian ini bertujuan untuk mengetahui kandungan senyawa antioksidan dan pengaruh rasio NADES pada daun kemangi. Proses ekstraksi daun kemangi menggunakan NADES dari Asam Sitrat dan Sukrosa dengan perbandingan rasio mol 1:1, 1:2 dan 2:1. Metode ekstraksi yang digunakan merupakan metode Ultrasound Assisted Extraction (UAE). Pengujian aktivitas antioksidan menggunakan metode DPPH (2,2-difenyl-1-pikrylhidrazyl). Nilai aktivitas antioksidan dari daun kemangi dinyatakan dalam nilai IC50. Pada rasio 1:1 adalah 37,58 µg/mL, pada rasio 1:2 adalah 96,45 µg/mL dan pada rasio 2:1 adalah 107,18 µg/mL. Aktivitas antioksidan terbaik dengan nilai IC50 37,58 µg/mL ditunjukan oleh ekstrak daun kemangi yang diekstrak dengan menggunakan NADES asam sitrat : sukrosa rasio mol 1:1.

Abstract

In terms of potential, the people of Palas Village mostly depend on the agricultural sector, industrial employees and fisheries in the river basin (DAS). One of the local potentials that is quite prominent is the existence of a Fishing Park on the banks of the Siak River (SUSI). With 6 floating houses and 2 fishing boats, it can improve the decent life for partners by seeing changes in their increasingly improving economic growth so that the sustainability of this program can be carried out in such a way. Implementation in the form of intensive implementation and assistance to produce mobile-based floating house empowerment products. The activities that have been carried out are the manufacture of 5 floating houses for a size of 2x2 meters and 1 unit with a size of 3x5 meters, as well as one unit of fiber boat made from new with a 7.5 Hp engine and repair of 1 unit of 20 Hp capacity boat, as well as the installation of a 100Wp solar panel lighting system and financial management and asset management training have also been carried out as well as social media-based marketing training.

Abstract

Emulsion stability is one of the key parameters in cosmetic formulation because it is directly related to product quality and consistency during storage. In Carbopol-based emulsion systems, the mixing process plays a major role in forming the gel structure and in the rheological properties of the final product. This study aims to examine the effect of mixing-speed variation on the viscosity and stability of a Carbopol system neutralized using NaOH. The mixing process was carried out at speeds of 1000, 1100, and 1200 rpm for 10 minutes, with a relatively constant Carbopol concentration. The observed parameters included changes in pH and emulsion viscosity, measured using a viscometer. The results show that all samples met the company’s pH and viscosity standards, with a mixing speed of 1100 rpm producing the highest viscosity value. These findings indicate that setting the appropriate mixing speed is essential for obtaining optimal emulsion stability in Carbopol-based cosmetic formulations.

Abstract

The refining process of crude palm oil (CPO-TO) into Refined Bleached Deodorized Palm Oil-Technical Oil (RBDPO-TO) requires a bleaching step to remove pigments and impurities. The use of bleaching earth (BE) at this stage plays a crucial role in improving oil quality, but has the potential to cause oil losses, which can reduce product yield. This study aims to analyze the effect of bleaching earth dosage on oil content, total oil losses, and RBDPO-TO yield in the refinery process. The study was conducted quantitatively using operational data and laboratory analysis results at PT XYZ Dumai during the period of December 1–14, 2025. The bleaching earth dosage varied between 0.8–1.5% with a relatively constant feed flow rate. The results showed a positive correlation between increasing bleaching earth dosage and oil content and total oil losses, and a negative correlation with RBDPO-TO yield. A high BE dosage (1.4–1.5%) resulted in the highest oil losses of up to 0.89% and the lowest yield of around 84.23%, while a lower BE dosage (0.8–0.9%) reduced oil losses to 0.50% and increased RBDPO-TO yield to 89.39%.

Abstract

Toxic heavy metals in aquatic ecosystems pose serious environmental and ecological risks. This study evaluates the adsorption performance of H3PO4-activated oil palm frond biochar for removing Pb(II) and Cu(II) from a multi element system. Competitive adsorption was simulated using Certified Reference Material (CRM) containing 23 elements. The optimized adsorbent dosages were 0.05 g for kinetic experiments and 0.01 g for isotherm experiments, with metal concentrations of up to 10 mg/L in 25 mL of solution. Metal concentrations were analyzed using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES 5800 VDV). Kinetic analysis over 180 min showed that the adsorption process followed the pseudo-second order model, while equilibrium data were best described by the Langmuir isotherm, indicating selective adsorption toward competing metal ions. The adsorbent demonstrated high removal efficiencies for Fe, Al, Cu, Pb, and Cr, exceeding 80%. These results indicate that H?PO?-activated oil palm frond biochar has strong potential as an effective adsorbent for treating wastewater containing multiple hazardous heavy metals.
