Abstract

The addition of activated charcoal to the cement matrix can increase the density and durability of the mortar. The purpose of this study was to analyze the effect of activated charcoal on the characteristics of composite mortar including compressive strength, density, and water absorption. Making mortar composite with the composition of activated charcoal to the weight of cement (1%, 2%, 3%, 4%, and 5%), the ratio of cement and sand is 1: 3. The composition will be tested and analyzed for its effect on the compressive strength, density, and water absorption of mortar composite. The results showed that the addition of activated charcoal did not have a significant effect on the characteristics of mortar composite, except for the setting density. The addition of activated charcoal by 5% showed an optimal composition with a compressive strength value of 11.67 MPa, a setting density of 2092.91 kg / m3, an oven-dry density of 1853.93 kg / m3, and a water absorption of 15.20%

Abstract

Seaweed dodol mixed agarwood infusion is an innovative culinary product from Lombok Island made primarily from seaweed flour. This research aims to conduct a sensory evaluation of seaweed dodol mixed agarwood infusion using the 9-point hedonic scale with different statistical approaches for the analysis. Four different seaweed concentrations were applied in this research as treatments: S1(seaweed flour 8% w/v), S2 (seaweed flour 10% w/v), S3 (seaweed flour 12% w/v), S4 (seaweed flour 14% w/v). The proximate analysis measures total protein, lipid, ash, water, and carbohydrates. This study used a Nine-point hedonic scale ranging from 9 (like extremely) to 1 (disklike extremely). Non-parametric statistics (Kruskal-Wallis and Freidman Test) and parametric statistics (ANOVA-CRD and ANOVA-RCBD) are the statistical approaches in this study, which are continued by DMRT (α = 0.05). Thirty trained respondents were evaluated based on appearance, aroma, taste, and texture. Proximate analysis shows that dodol has high moisture with medium carbohydrate content. The result shows that different statistical approaches have a consistent critical P-value, which shows the highly significant effect of treatment on the sensory evaluation value. DMRT analysis shows that the higher seaweed flour concentration results in a higher numerical hedonic value. The spider web chart shows respondents give a more sensitive evaluation of taste and texture than appearance and aroma. It could be concluded that different statistical approaches are reliable for analysing the significant effect of different seaweed flour concentrations on the sensory evaluation value of seaweed dodol mixed agarwood infusion.

Abstract

This study aims to analyze science students’ attitudes toward environmental conservation issues and actions, with a focus on understanding personal commitment, emotional engagement, conservative values, and appreciation for environmental education. Employing a mixed-methods approach, quantitative data were obtained from 43 students through a five-point Likert-scale attitude questionnaire, while qualitative data were collected through in-depth interviews with six selected respondents. Quantitative analysis revealed an average attitude score of 24.56, categorized as "Low", with the majority of respondents (55.81%) showing a weak level of concern toward environmental conservation issues. No respondents fell into the "Very Good" category, and only 6.98% were classified as "Good". The qualitative analysis indicated that, although students expressed normative awareness of the importance of conservation, their involvement remained situational, influenced by social context, and constrained by academic pressure and limited community support. The findings emphasize the need for reform in environmental education at the university level, particularly in integrating affective dimensions, personal values, and psychosocial empowerment. The implications highlight the importance of a transformative and participatory curriculum to foster strong and sustainable pro-environmental attitudes among science students.

Abstract

Lemongrass and agarwood are potential forest herbal tea products which need to be further explored based on research and development schemes. The purpose of this research is to conduct a sensory evaluation using a 9-point hedonic scale and different statistical approaches on mixed lemongrass beverages and agarwood infusion. Four treatments are used in this research including: L1 = Lemongrass concentration 0.1% w/v, L2 = Lemongrass concentration 0.2% w/v, L3 = Lemongrass concentration 0.3 % w/v, L4 = Lemongrass concentration 0.4% w/v. This research used 4 different statistical approaches including Kruskal-Wallis, Freidman Test, ANOVA-CRD, and ANOVA-RBCD. Sensory evaluation was conducted using a 9-point hedonic scale using 30 trained respondents on 4 parameters including appearance, aroma, taste and bitterness. The results show that all statistical approaches give sensitive analysis for P-value measurement except for the Freidman Test. Appearance is the only parameter with a significant p-value in all statistical approaches. Different treatments show different maximum hedonic score values on different parameters, and they are significantly different based on DMRT results. However, based on the area of the spider web chart, L2 has the largest impact on hedonic score value compared to other treatments. It could be concluded that Treatment L2 (lemongrass concentration of 0.2% w/v) has the highest hedonic evaluation score which shows that this is the effective concentration to produce beverage products with good acceptability.

Abstract

The world's demand for wood is increasing while the amount of solid wood production is decreasing with the depletion of forestsdue to illegal logging and conversion of forest functions as plantation land. To overcome these problems, it is necessary to do theefficiency of wood raw materials so that the use of solid wood can be reduced. One of the efficient ways to use wood raw materials isto utilize optimized wood industrial waste by combining one or more types of wood which are glued together into a single unit,commonly called a laminated board. In this study, we will look at the effect of different types of wood and the weight of the gluespread on the resulting laminated board. Advantages Laminate board can produce a board size that is wide and long as neededbecause the joints are made as long as needed. In the manufacture laminated boards are made with the type of wood, namely jatiputih (Gmelina arborea. Roxb), bajur (Pterospermum javanicum), sengon (Paraserianthes falcataria) and mixtures(jati putih, bajur and sengon) and the glue spread factor is 150 g and 200 g. Then the physical and mechanical properties weretested. The test results showed that the wood type had a significant effect on all physical and mechanical properties except for thethickness shrinkage and MoE tests. The interaction of the lamination glue spread factor and the wood type factor did not significantlyaffect all physical and mechanical properties of mixed wood waste laminated boards. Based on the test results, laminated board isclassified as strong class III which can be used as a lightweight construction material indoors.

Abstract

The phytochemical profile of tea beverages under different brewing conditions should be further examined using sensory evaluation to measure preference levels, which are essential for product development. This study aims to comprehensively review the sensory profile of tea beverages with different adjustments to the brewing conditions from recent 10-year publications. This study used the methodological standards outlined in the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) across five databases (Scopus, Web of Science, ScienceDirect, ProQuest, and CABI). The Office of Health Assessment and Translation (OHAT) was used for risk bias assessment. A total of 1555 articles were identified, yielding 24 eligible studies. Various brewing conditions were identified in the study, mostly adjusted across three parameters: tea-to-water ratio, brewing temperature, and brewing duration. Preference level quantification is conducted using different hedonic scales with varying point levels, including 3-point, 5-point, 9-point, and 10-point scales. The quality assessment of tea is measured using various standards, including: Chinese national standard for sensory evaluation of tea, Check All That Apply (CATA), Percentage grading system, unstructured quantitative descriptive analysis, and degree of satisfaction difference. It could be concluded that studies about brewing condition in tea are focused on hot brewing and cold brewing with the optimum value of tea to water ration is 1:50. The sensory evaluation of tea from this different brewing condition is mainly conducted by trained panelists using 10-point hedonic scales as quantitative preference level and Chinese national standard for sensory evaluation of tea as a quality assessment method.

Abstract

Wastewater management is one of the issues at the heart of the Sustainable Development Goals. This is urgent because waste that is not properly managed can cause damage to water bodies, reducing clean water sources that can be used for household, office and industrial needs. One of the low-cost yet effective wastewater management strategies which also produce valuable products is the use of microalgae as remediators to improve the quality of polluted waters. The aim of this study was to evaluate the efficiency of H. pluvialis culture as a bioremediator for tofu effluent. The research stages consisted of activation of H. pluvialis microalgal starter in Walne medium, followed by cultivation of microalgae in tofu effluent medium, observation of microalgal growth in the effluent, and measurement of water quality parameters such as pH, colour, BOD and COD, as well as the aroma of tofu effluent before and after use as a microalgal growth medium. According to the growth curve of H. pluvialis in the tofu wastewater medium, it is known that this microalgae can grow well in the effluent and can improve wastewater quality. Where the pungent odour typical of soya waste began to disappear from the second day of cultivation, the pH increased from acidic to neutral, and BOD and COD levels were drastically reduced. In conclusion, H. pluvialis microalgae can be used as a bioremidiator of tofu ffluent as it can effectively improve the quality of the wastewater.
