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.

Abstract

The invention of agarwood is crucial for the downstream application of agarwood research results in Indonesia. This study aims to review the invention of agarwood in Indonesia over the past 8 years. According to the Indonesian Intellectual Property Database, the average number of agarwood inventions in Indonesia from 2018 to 2025 is approximately five inventions per year. This number is much lower than the average number of agarwood publications during the same period, which can reach 81 publications per year. Agarwood leaf utilisation accounts for the dominant proportion of the invention, which is equally derived from the Aquilaria and Gyrinops genera. Most of the invention is intended to produce health products that confirm the health-beneficial effects of agarwood, based on research. The invention of agarwood in Indonesia was dominated by simple patents, which are easier to register compared to other types of patents. The proportion of rejected inventions to granted inventions is 1:6, indicating a medium difficulty level of invention registration in Indonesia. The invention right holder is dominated by higher education institutions (70%), followed by research institutions with a proportion of less than 20%. Invention registration location data reveal the uneven distribution of agarwood inventions, which is dominated by three islands: Java, Sumatra, and Kalimantan. It can be concluded that the invention of agarwood in Indonesia is very limited compared to the number of publications, with a minimal contribution from the Industrial sector.

Abstract

Penelitian ini bertujuan untuk melakukan studi diversitas melalui analisis numerik fenetik terhadap kromatogram GC-MS minyak gaharu dari genus Aquilaria. Data kromatogram hasil GC-MS 4 spesies Aquilaria yaitu: A. malaccensis, A. crassna, A. sinensis dan A. subintegra diperoleh dari database online dan ditabulasi dalam tabel n x t. Sebanyak 5 indeks similaritas (Simple Matching Coefficient, Jaccard’s Coefficient, Nei & Li Coefficient, Sorensen’s Coefficient, dan Baroni-Urbani Buser Coefficient) dan 3 algoritma klasterisasi (Nearest Neighbor, UPGMA dan Farthest Neighbor) digunakan dalam analisis klaster. Analisis kofenetik kovarian dilakukan untuk menentukan indeks similaritas dan algoritma optimum berdasarkan nilai r sebagai dasar dalam konstruksi dendrogram. Analisis principal coordinate (PCoA) dilakukan dengan menggunakan algoritma Euclidean dan pendekatan Kaiser’s rule sebagai tambahan analisis yang lebih komprehensif. Sebanyak 68 komponen senyawa berhasil ditabulasi dalam tabel n x t yang dikonversi menjadi angka biner untuk analisis klaster. Hasil analisis kofenetik kovarian menunjukkan nilai r terbesar dan sangat signifikan (α=0,05) dihasilkan dari indeks similaritas simple matching dan algoritma klasterisasi UPGMA sehingga kedua parameter ini digunakan dalam konstruksi dendrogram. Topologi dendrogram menunjukkan similaritas yang rendah antar spesies Aquilaria dengan similaritas tertinggi dimiliki oleh klaster A. subintegra dan A. malaccensis. Grafik 3 dimensi dari PCoA juga menunjukkan hasil releven dengan dendrogram dengan plotting keempat spesies Aquilaria tersebar pada 3 kuadran yang berjauhan sehingga menunjukkan jarak similaritas yang juga berjauhan. Dapat disimpulkan bahwa berdasarkan analisis numerik fenetik, minyak gaharu dari A. crassna, A. malaccensis, A. subintegra dan A. sinensis memiliki karakteristik fitokimia berupa kromatogram GC-MS yang unik dengan diversitas yang tinggi.

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

This research aims to evaluate sensory using a 9-point hedonic scale and different statistical approaches on cookies made from Rhizopora propagule flour. This research used flour made from Rhizopora propagule and wheat flour with varying compositions to make cookies (C1= Rhizophora flour 100% wheat flour 0%, C2 = Rhizophora flour 75% wheat flour 25%, C3 = Rhizophora flour 50% wheat flour 50%, C4 = Rhizophora flour 25% wheat flour 75%). Respondents gave evaluations using a 9-scale hedonic score for the treatments in 4 parameters, including appearance, aroma, taste, and texture. Evaluation scores were analysed using four statistical approaches: Kruskal-Wallis, Freidman, ANOVA-CRD, and ANOVA-RCBD. The results show that different treatments resulted in significantly different respondent evaluation scores. All respondents give evaluation scores higher than the threshold except for C1. This result means that the addition of wheat flour is still needed in Rhizophora cookie production. All treatments have the same evaluation score in appearance treatment, while C3 and C4 treatments have the highest evaluation scores in aroma, taste, and texture. It could be concluded that the potency of Rhizophora flour from its propagule as an ingredient in cookies is confirmed based on sensory evaluation using a 9-point hedonic scale and the ANOVA-RBCD statistical approach.

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.
