Abstract

The buildup of sugarcane bagasse fiber and coconut pulp fiber will cause rotting and an unpleasant odor, therefore it needs to be handled seriously. One of them is making natural fiber composites. The aim of the research was to obtain the highest tensile test value for a hybrid composite of coconut fiber and sugarcane fiber in the roots, stems and shoots with a volume fraction of 10% sugarcane fiber - 20% coconut fiber, 20% sugarcane fiber - 10% coconut fiber and sugarcane fiber. 15% - Coconut Fiber 15%, with 5% NaOH alkaline treatment for 2 hours. Samples were made using the hand lay-up method. The analysis was carried out using the direct experimental design method. The result was the highest tensile strength of 17.2 Mpa at a volume fraction of 10% Sugarcane Fiber - 20% Coconut Fiber and there was a decrease in tensile strength at a volume fraction of 20% Sugarcane Fiber - 10% Coconut Fiber. The lowest tensile strength is at a volume fraction of 20% Sugarcane Fiber - 10% Coconut Fiber with a tensile test strength value of 6.6 Mpa, meaning that the more fiber distribution in the resin in each composite will strengthen the bond between the matrix and fiber which causes the composite to be strong and not brittle. . In the micro photo, soaking in 5% NaOH for 2 hours was not able to clean the dirt or film attached to the coconut fiber, whereas in sugar cane fiber, soaking for 2 hours was able to clean the layer or dirt on the fiber. Dirt that sticks to it will affect the bond between the fiber and resin.

Abstract

One source of natural fiber whose utilization still needs to be developed is fiber from corn husk which is cheap, abundant and environmentally friendly. The increasing production of corn plants causes an increase in corn husk waste which is also higher. Even though this corn husk has very strong fiber and can be used as a composite of natural fibers. Composites reinforced with natural fibers have excellent corrosion resistance properties, as well as lower production costs, are more abundant and are considered to be more environmentally friendly. The aim of the study was to determine the effect of soaking 7% NaOH for 1 hour, 2 hours and 3 hours and the effect of curing time at temperatures of 95°, 105° and 115° for 4 hours on the tensile strength of the corn husk fiber woven composite and to determine whether corn husk woven fiber composite can be applied as a car bumper manufacture. Making samples using the hand lay-up method. The analysis was performed using the factorial method. The highest results were found in the tensile test specimens using a variation of NaOH immersion time for 2 hours at a temperature of 95°C having a tensile test strength of 19.93 MPa. Meanwhile, the lowest tensile test strength value was 12.13 MPa using a variation of NaOH immersion time for 3 hours with a temperature of 115°C. Based on the standard for making car bumpers, the corn husk woven fiber composite can be applied as an alternative material for making car bumpers.

Abstract

The rapid growth of the digital economy in Indonesia has increasingly exposed Muslim university students to consumerist ideologies that frequently conflict with the ethical foundations of Islamic finance. Despite the efforts of student organizations like the Forum Silaturahmi Studi Ekonomi Islam (FoSSEI) to promote Islamic financial literacy through education and experiential learning, many students continue to exhibit consumptive behaviors shaped by peer influence, digital culture, and low financial awareness. This study aims to examine the role of Islamic financial literacy and lifestyle in shaping the consumptive behavior of Muslim students, with a specific focus on FoSSEI members in West and Central Sumatra. Utilizing a quantitative approach, data were collected through a validated questionnaire from 210 students, with 206 valid responses analyzed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The results show that Islamic financial literacy affects consumption behavior both directly and indirectly through lifestyle. Furthermore, lifestyle significantly influences consumptive behavior and serves as a mediator that strengthens or weakens the effect of financial literacy. These findings reveal that knowledge alone is insufficient; instead, lifestyle serves as a crucial behavioral channel through which financial literacy manifests. Theoretically, the study contributes by integrating lifestyle as a key mechanism in Islamic financial behavior models. Practically, the findings suggest that financial education programs must go beyond knowledge transfer to include lifestyle transformation, fostering more ethical and sustainable consumption aligned with sharia principles. Recommendations are offered to educators, policymakers, and Islamic financial institutions for designing more holistic interventions. Abstrak Literasi Keuangan Syariah dan Pola Konsumsi Mahasiswa Muslim di Indonesia. Di tengah pesatnya pertumbuhan ekonomi digital, mahasiswa Muslim di Indonesia semakin terpapar gaya hidup konsumtif yang sering kali bertentangan dengan etika keuangan Islam. Meskipun beberapa organisasi, seperti Forum Silaturahmi Studi Ekonomi Islam (FoSSEI) telah berupaya meningkatkan literasi keuangan syariah melalui program edukasi dan pembelajaran berbasis pengalaman, masih banyak mahasiswa dengan pola konsumsi berlebihan akibat pengaruh tekanan sosial, budaya digital, dan rendahnya kesadaran finansial. Penelitian ini bertujuan untuk menganalisis peran literasi keuangan syariah dan gaya hidup dalam membentuk perilaku konsumtif mahasiswa Muslim, dengan fokus khusus pada anggota FoSSEI di Sumatera Barat dan Sumatera Tengah. Menggunakan pendekatan kuantitatif, studi ini mengumpulkan data-data penelitian dengan kuesioner yang terstandarisasi dari 210 mahasiswa, dengan 206 respons yang valid. Hasil analisis dengan metode Partial Least Squares - Structural Equation Modelling (PLS-SEM) menunjukkan bahwa literasi keuangan syariah berpengaruh terhadap perilaku konsumtif secara langsung dan tidak langsung melalui gaya hidup. Gaya hidup juga terbukti memiliki pengaruh signifikan dan menjadi mediator penting yang memperkuat atau melemahkan efek literasi keuangan. Temuan ini menegaskan bahwa pengetahuan saja tidak cukup; gaya hidup menjadi saluran perilaku yang penting dalam mengaktualisasikan literasi keuangan. Kontribusi teoretis studi ini adalah integrasi gaya hidup sebagai mekanisme utama dalam model perilaku keuangan syariah. Secara praktis, studi ini merekomendasikan agar program literasi keuangan syariah tidak hanya berfokus pada pengetahuan, tetapi juga transformasi gaya hidup untuk mendorong konsumsi yang lebih etis dan berkelanjutan sesuai prinsip syariah.

Abstract

Background: Stunting prevention can be accomplished by augmenting maternal knowledge through education that employs locally accessible nutrient-rich foods to facilitate children's growth and development. This entails converting moringa leaves into moringa cake and mackerel tuna into chips as nutritional snack alternatives and flavor enhancers to substitute MSG, thereby supporting the Free Nutritious Meal Program (MBG). Objectives: This study aimed to determine the impact of the educational program on the processing of moringa cake, tuna-based flavor enhancers, and mackerel tuna chips for stunting prevention toward the knowledge of the Family Welfare Movements (PKK) mothers in Tongali Village. Methods: The study used a quasi-experimental design. The sampling method used was accidental sampling, comprising a sample size of 40 respondents. Bivariate analysis was performed utilizing the One Group Pretest-Posttest Design with the Wilcoxon Signed Rank test. Results: Bivariate analysis demonstrated that the educational program significantly influenced the knowledge of PKK mothers before and after their implementation (Prob > |z| = 0.0000 < 0.05). Conclusions: This study aimed to enhance the engagement of PKK mothers in the utilization of moringa leaves and mackerel tuna for the preparation of nutritious foods, diminish the reliance on MSG to mitigate stunting, and bolster the local economy.
