Abstract

Seaweed (Eucheuma cottonii) is an abundant marine commodity in Indonesia, used for gelatin and carrageenan in food, pharmaceutical, and cosmetics industries, while sweet potato is one of crop commodities as a source of carbohydrates having potential for food diversification and agro-industry, such as noodle. The main concern characteristic of noodle is chewiness and elasticity. The aim of this study was to determine the effect of seaweed flour addition and the ratio of purple of sweet potato paste on quality of noodle. The research was conducted by using Completely Randomized Design (CRD) consisting of two factors, namely seaweed flour concentration (P) (10%, 20%, 30%), and ratio of sweet potato paste (R) (50:50, 60:40, 70:30). The results showed that the addition of seaweed flour (P) had no significant effect on water content, cooking time, organoleptic test regarding color, taste, and elasticity, but it had effect on ash content, water absorption capacity, and breaking strength. On the other hand, ratio of sweet potato had no significant effect on ash content, breaking strength, cooking time, and organoleptic tests of color, taste, and elasticity. The interaction between those two factors had effects on water and ash content. The best treatment was adding 30% of seaweed flour with ratio of sweet potato paste 60:40, in which 62.2% water content, 0.92% ash, 61% water absorption, 13 cm breaking strength, 2.15 minutes, and usual acceptance of organoleptic parameters (color, taste, elasticity). Keywords: Elasticity; noodle; purple sweet potato paste; seaweed flour

Abstract

A study was conducted on the treatment of palm oil liquid waste using activated bentonite through an adsorption method. Four variations of adsorbent treatments were employed: untreated bentonite (UBA), and chemically activated bentonite with 5%, 10%, and 15% H2SO4 (CAB-5, CAB-10, and CAB-15, respectively). The adsorption capacities (qe) for UBA, CAB-5, CAB-10, and CAB-15 were found to be 91.01, 97.01, 94.46, and 93.27 mg/g, respectively. The adsorption kinetics followed a first-order reaction model, with correlation coefficients (R2) of 0.70, 0.93, 0.98, and 0.94 for UBA, CAB-5, CAB-10, and CAB-15, respectively. Additionally, the fatty oil content of the treated waste, when adsorbed for 60 to 100 minutes, met the quality standard threshold, reducing it to below 25 mg/L. This study underscores the importance of addressing the waste produced by the palm oil industry and emphasizes the need for effective effluent treatment to protect the environment and ensure industry sustainability.

Abstract

The natural resources of agricultural products have the potential to be raw material for making biodegradable plastic, one of which is starch from kluwih seeds (Artocarpus camansi). This study examines the potential of kluwih seed starch as a basic material for making biodegradable plastic. This research method is experimental, the raw material for making biodegradable plastic is the kluwih seed starch originating from Aceh Besar Regency, Aceh Province. Other additives used are chitosan as reinforcement and glycerol as plasticizers. The analysis is carried out, namely mechanical properties, morphology, thermal, functional groups, water absorption and degradation analysis. The results of the analysis of this study show that the kluwih seed starch functions as a basic material for making biodegradable plastic. As chitosan concentration increases, the resulting tensile strength increases with results obtained around 119.17-166.67 kgf/mm2, while the percentage of elongation is lower the results obtained are 6.82-11.15%. The morphological analysis shows the biodegrable plastic produced has a compact and homogeneous structure. The thermal analysis shows a good thermal stability to ranging from 180 to 370 oC. The results of the biodegradable plastic FTIR show wave numbers 1662.64–1049 cm-1. Water absorption analysis is obtained around 7.658-12.068%, a decrease in water absorption is influenced by the addition of chitosan concentration. Biodegradable paltic planted in the soil containing EM4 degraded for 3 days.

Abstract

Papaya (Carica papaya L.) is a tropical plant known for its various health benefits. Almost all parts of this plant, including its roots, contain phytochemical compounds such as flavonoids, alkaloids, saponins, and papain enzymes with potential anti-inflammatory properties. This study aimed to develop an anti-inflammatory cream based on papaya root waste extract, providing a natural therapeutic solution for skin inflammation. Papaya roots were obtained from Laweung, Pidie Regency, and processed using maceration with 96% ethanol solvent, yielding an extract with a 26% recovery rate. Phytochemical analysis revealed the presence of flavonoids, phenolics, tannins, alkaloids, terpenoids, and saponins.The cream formulation was developed with varying extract concentrations: F0 (control), F1 (1.2 g), F2 (1.6 g), and F3 (2.0 g). Based on organoleptic testing, the cream formulations showed good stability in terms of color, aroma, and texture during storage. The added rose oil provided a pleasant fragrance that meets the SNI cosmetic standards. The pH test results indicated that all formulations (F0 to F3) were within the safe range for skin application, between 5.2 and 6.4. Formula F3 had the lowest pH (5.2), but it still complied with the SNI standard. The spreadability test showed varying results, with F0 having the highest spreadability (8.1 cm), while formulas with papaya extract (F1 to F3) showed spreadability ranging from 6.06 to 7.1 cm. The viscosity of the cream increased with higher extract concentrations, with F0 having the lowest viscosity (10,000-10,800 cPs) and F3 the highest (19,000 cPs). Homogeneity testing confirmed that all formulations had uniform distributions without phase separation. In conclusion, the cream based on papaya root waste extract has potential as a natural anti-inflammatory product with physicochemical stability suitable for topical use and adds value to plant waste.

Abstract

Nyamplung (Calophyllum inophyllum L.) is a plant commonly found in coastal areas and lowlands. In Aceh, it is locally known as boeh beunot, a coastal species that grows easily and has various local names in different regions. This plant belongs to the Clusiaceae Lindl. Family and can be propagated both vegetatively (cuttings) and generatively (seeds). Nyamplung begins to bear fruit at the age of 5–20 years and can produce throughout the year, with peak harvest occurring in May–June. Fruit production can reach up to 20 tons/ha/year or approximately 250 kg/tree/year. In this study, nyamplung seeds originating from Aceh Province were utilized as a source of bioactive compounds for the formulation of transparent solid soap with antioxidant properties. The research stages included sample preparation (drying, peeling, and size reduction into powder), followed by extraction using the maceration method. Extraction optimization was carried out using the Response Surface Methodology (RSM) approach with Box-Behnken Design (BBD), involving three main factors (sample amount, extraction time, and solvent volume) at three levels (low, medium, and high). The obtained nyamplung seed extract was characterized through phytochemical analysis, GC-MS testing, and antioxidant activity assays. Optimization results indicated the best conditions were achieved with 200 g of sample, 1,000 mL of solvent, and 36 hours of extraction, yielding antioxidant activity with an IC₅₀ value of 18.5 ppm. Phytochemical tests identified the presence of phenolics, flavonoids, terpenoids, steroids, and saponins. The extract with the highest antioxidant activity was subsequently formulated into antioxidant transparent solid soap. Characterization of the transparent soap formulated with nyamplung seed oil showed a pH of 10.53, which remains within the safe range for alkali-based soaps. The measured moisture content was 15.05%, indicating good physical stability and a low risk of microbial growth. Furthermore, skin irritation tests revealed no signs of redness, itching, or allergic reactions, confirming that the soap is safe for human skin.

Abstract

This study aimed to evaluate the performance of a tofu-dregs-based polyurethane adsorbent in removing Zn(II) ions and to examine its effects on the moisture content, ash content, and pH variation in oysters (Crassostrea spp.), as well as to assess compliance with Indonesian National Standards. The method used in this study involved exposing fresh oysters to ZnSO₄ solutions at concentrations of 2, 4, and 6 ppm for 60 minutes in the presence of the composite adsorbent. Moisture content was determined gravimetrically at 105 °C, ash content by dry ash at 550 °C, and pH was monitored throughout the contact period. The results showed that the moisture content of fresh oysters remained stable at 89–91% before and after adsorption, while dried oyster samples had reduced moisture levels of 11.0–11.8%, meeting the ≤ 12% limit for dried products. The ash content of the adsorbent increased from 3.00% to 7.80–9.60%, indicating effective retention of Zn(II) ions, whereas the ash content of oysters remained relatively constant at 1.90–1.96%, suggesting minimal accumulation of metal ions in the tissues. A gradual increase in solution pH during the adsorption process confirmed chemical interactions between Zn²⁺ ions and functional groups on the adsorbent surface. These findings demonstrate that the tofu-dregs-based polyurethane adsorbent is effective for Zn(II) removal while maintaining oyster quality within national safety standards, highlighting its potential as an environmentally friendly material for heavy-metal remediation.
