Abstract

Nori merupakan makanan kering berbahan baku rumput laut Porphyra sp. Ketertarikan masyarakat terhadap nori berdampak pada nilai impor produk nori yang meningkat setiap tahunnya. Ketersediaan rumput laut Porphyra sp. sebagai bahan baku nori terbatas. Oleh karena itu, diperlukan bahan baku alternatif pengganti Porphyra sp. dalam pembuatan nori. Rumput laut yang melimpah di perairan Indonesia dan berpotensi sebagai bahan baku nori, di antaranya Ulva lactuca, Gracilaria sp., dan Euchema spinosum. Pemanfaatan rumput laut lokal menjadi produk nori memerlukan tambahan bahan sebagai penyalut. Tujuan penelitian ini adalah menentukan penyalut terbaik dalam pembuatan nori berdasarkan karakteristik sifat sensori dan nilai proksimat. Penelitian menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) dengan perbedaan variasi penyalut nori-like product. Penelitian dilakukan tiga tahap, yaitu preparasi rumput laut, pembuatan nori, dan proses penyalutan nori. Hasil penelitian menunjukkan nilai organoleptik produk nori dengan penyalut 100% tapioka (F2) lebih disukai panelis dengan nilai rata-rata organoleptik warna 7,89%, tekstur 7,27%, ketampakan 8,42%, aroma 8,02%, rasa 7,84%, dan keseluruhan 7,89%. Variasi penyalut meningkatkan nilai sensori kerenyahan produk nori berbahan rumput laut lokal. Hasil analisis karakteristik kimia menunjukkan bahwa produk nori U. lactuca, Gracilaria sp., dan Eucheuma spinosum dengan variasi penyalut berbeda mempunyai nilai yang berbeda pula. Nori F2 memiliki kandungan protein 8,82%, lemak 20,16%, air 10,31%, abu 12,43%, dan karbohidrat 48,28%. Produk nori rumput laut U. lactuca, Gracilaria sp. dan Eucheuma spinosum dengan variasi penyalut layak untuk dikembangkan lebih lanjut sebagai produk komersial dari rumput laut lokal.

Abstract

Chaetomorpha crassa is a green seaweed that is abundant in Indonesian waters. The utilization of C. crassa is yet to be fully optimized, as seaweed farmers often view it as a nuisance. However, this seaweed contains natural cellulose, which can be used in industrial applications. Consequently, this study aims to determine the optimal temperature for cellulose extraction from C. crassa, focusing on cellulose content, physical characteristics, and diffraction patterns. The cellulose extraction process involves several stages: depigmentation and delignification at extraction temperatures of 60, 70, and 80°C for 12 h, followed by depolymerization using 5% HCl. The biomass was dried at 60°C for 10 h. The parameters analyzed included the degree of crystallinity, density, flowability index, and porosity, as well as the cellulose, lignin, hemicellulose content, and diffraction patterns. The findings indicated that variations in extraction temperatures of 60°C, 70°C, and 80°C significantly affected (p<0.05) the cellulose, lignin, hemicellulose, bulk density, tap density, Carr's index, Hausner ratio, and porosity. The optimal conditions for cellulose extraction were achieved at a temperature of 70°C, resulting in an average cellulose content of 74.17%, a degree of crystallinity of 64.13%, bulk density of 0.21 g/cm³, tap density of 0.29 g/cm³, Carr's index of 35.11%, Hausner ratio of 2.48, and porosity of 1.27. Diffraction analysis revealed that the cellulose obtained in this study was predominantly type II cellulose (72.66%), with type I cellulose comprising 27.34%.

Abstract

The objective of this research is to develop and test the demonstration tool of Arduino based air heater controller with Proportional Integral Derivative (PID) based control methods for the temperature range between 50ºC and 70ºC.   Arduino Uno was programmed using C-language to do control tasks and to transfer control data serially to computer via USB port. The selection of the initial PID  parameters are determined using the combination of Relay Feedback method and Ziegler-Nichols  formula.  The control methods were focused on proportional (P), proportional derivative (PD) dan Proportional Integral Derivative (PID) with the performance criteria based on overshoot  dan steady state error.  The experimental results show that the PID controllers give best output responses in terms of zero steady state errors, while P and PD controllers still result in steady state errors of about 3ºC. In addition, P controllers still give about 2,5ºC-4ºC fluctuative output values below set points, while the PD and PID have very small fluctuative values and even very close to zero. This laboratory demonstration tool has shown very good PID based controller performance, so it is feasible to be used as a supporting demonstration tool for control system laboratory in Politeknik Negeri Semarang or even other universities.

Abstract

The physics laboratory plays an essential role in science learning as it supports experiments that enhance students’ conceptual understanding and learning interest. This study aimed to analyze the standardization level of the physics laboratory at SMA Negeri 1 Turi and its relationship with the learning interest of grade X and XI students. A descriptive method with a mixed-methods approach using an Explanatory Sequential design was employed through observation, questionnaires, interviews, and documentation. The results showed that laboratory infrastructure (90%) and facilities (87%) were categorized as very good, while personnel (33%) were lacking and management (62.7%) was only sufficient. Laboratory implementation in learning scored (67.5%) in the good category, but its use as an assessment tool was not optimal. Questionnaires and interviews indicated that practicum activities increased students’ enthusiasm, although limited personnel and weak management made them irregular. Thus, the physics laboratory at SMA Negeri 1 Turi is very good in infrastructure and facilities but requires improvement in personnel and management to effectively support students’ learning interest.Keywords: laboratory standardization; management; learning interest; physics

Abstract

This study investigates the enhancement of religious moderation by implementing Islamic religious education values at Public Senior High School 1 Bambanglipuro, Bantul. Employing a descriptive qualitative research design, data were gathered using observations, semi-structured interviews, and document analysis. The research is underpinned by Thomas Lickona's theory of value education, emphasising the role of value education in shaping character and behaviour. Participants included the principal, teachers, and students selected through purposive sampling to provide comprehensive insights. The findings highlight integrating critical Islamic values such as faith, honesty, obedience, and tolerance into the school's curriculum. These values are conveyed through classroom activities, extracurricular programs, and school culture, resulting in notable improvements in student behaviour, reduced inter-religious conflicts, and enhanced attitudes of tolerance and respect. The study underscores the effectiveness of Islamic religious education in promoting religious moderation and fostering a peaceful and pluralistic society. Implications for educational policy and practice are significant, suggesting that incorporating structured moral education can play a crucial role in achieving societal harmony. Recommendations include the nationwide adoption of similar educational programs and ongoing professional development for educators to ensure sustained positive impacts. Future research should expand to include more schools and regions to validate these findings further and explore additional factors influencing the success of religious moderation initiatives in educational settings.

Abstract. Kusumawardana A, Ilyas S, Qadir A, Trikoesoemaningtyas, Human S, Sihono. 2026. Radicle emergence as a rapid indicator of sorghum seed vigor to predict mean germination time, vigor index, and field emergence. Asian J Agric 10 (1): g100124. https://doi.org/10.13057/asianjagric/g100124. This study aimed to develop a standardized radicle emergence test for sorghum (Sorghum bicolor) seeds by determining the optimal single-count timing and temperature for the simultaneous assessment of seed vigor and viability. This test was conducted by calculating the percentage of seeds whose radicles had emerged by at least 2 mm in length during a single observation period at the beginning of germination. Seed lots with low radicle emergence rates showed slow germination, reflecting an early physiological indicator of seed deterioration and a key factor contributing to reduced vigor. The experiment was arranged in a randomized complete block design with one factor: 12 sorghum genotypes, and four replications (blocks). Radicle length was measured at 2-h intervals from 40 to 48 h, with a minimum length of 2 mm. Results of radicle emergence (production of 2 mm radicle) at 25°C and alternating temperatures 20⇔30°C for 44 h (the optimal time), mean germination time, germination percentage, germination speed, vigor index, maximum growth potential, tetrazolium test, and field emergence were compared using 12 genotypes of sorghum seeds with standard germination above 83%. The single counts of radicle emergence performed at 25°C and 20⇔30°C were highly correlated with key vigor and viability indicators. Correlations with vigor-related traits, such as mean germination time (R²=0.87-0.81), vigor index (R²=0.83-0.89), germination speed (R²=0.73-0.71), and field emergence (R²=0.77-0.70), were strong, as were those with viability parameters, including standard germination (R²=0.66-0.59) and tetrazolium test results (R²=0.58-0.52). This study concludes that a single count of radicle emergence at 44 h, conducted at either 25°C or 20⇔30°C, is a method for simultaneous assessment of seed vigor (mean germination time, vigor index, germination speed, and field emergence) and viability in sorghum, offering a significant improvement over more time-consuming tests, such as germination test that requires 10 days.

Abstract

Efficient storage and retrieval of electronic components remain challenging in laboratory-scale environments due to reliance on manual handling. This study presents the development and experimental evaluation of a laboratory-scale three-axis Automated Storage and Retrieval System (ASRS) prototype designed for electronic component management. The proposed system uses a combination of servo and stepper motors to provide controlled motion along the X, Y, and Z axes. It is managed by a Programmable Logic Controller (PLC) integrated with a Human–Machine Interface (HMI). Manual operation is used for system calibration and motion adjustment, while automatic operation facilitates sequential storage and retrieval processes. We evaluated the system's performance by measuring positional accuracy and deviation at multiple target rack locations. The results show that the system achieves positioning accuracy of 84.62% - 95.38%, with absolute deviations between 0.3 and 1 cm. These findings demonstrate that the ASRS prototype is a feasible solution for effective laboratory-scale automation in storage applications and for PLC-based educational purposes.

Abstract

The development of Islamic Religious Education curriculum in Indonesia increasingly emphasizes the integration of psychological principles to address the mental, emotional, and social needs of students. This approach aims to create a balanced learning experience that not only imparts knowledge but also fosters holistic character development. Research reveals that an academically focused curriculum often neglects students' psychological well-being, leading to decreased motivation and limited character formation. This research uses the literature study method by analysing various literatures related to developmental psychology, learning psychology, and the humanistic approach in education. Findings from this study highlight three key results: first, the relevance of psychological principles in bridging cognitive and emotional aspects of education; second, the practical strategies for embedding psychological frameworks into curriculum design to encourage student engagement and empathy; and third, the measurable impact on students’ moral development and interpersonal skills. Through a responsive curriculum aligned with Indonesia's educational goals, educators can foster an environment conducive to the intellectual, moral, and emotional growth of students. Therefore, through a qualitative literature study, this article provides conceptual insights and recommendations for the implementation of a psychologically enriched curriculum framework in Islamic Religious Education.
