Abstract

Thermal and surface properties of LiFePO4/very-few-layer graphene (LiFePO4/VFLG) composite manufactured through the sol-gel route have been researched for lithium-ion battery cathode application. VFLG was acquired from a facile, cost-effective, and environmentally benign fluid dynamic shear exfoliation process. The composites were characterized through thermogravimetry analysis (TGA), differential scanning calorimetry (DSC), field-emission scanning electron microscopy (FESEM) interlinked with energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and Braneur-Emmett-Teller (BET) analysis. The TGA-DSC results showed that the integration of VFLG could enhance the thermal stability of the composite by inhibiting oxygen diffusion on the LiFePO4 surface. FESEM-EDX analysis, meanwhile, confirmed the homogeneously distributed VFLG in the composites. TEM results revealed that the average particle sizes of the composites decreased by about 21.2% compared to the bare LiFePO4. TEM and HRTEM results confirmed an intimate contact between VFLG intimately and LiFePO4 particles via plane-to-point contact, contributing to the control and reduction of particle size. Furthermore, physisorption via BET analysis revealed that incorporating VFLG provided a wider distribution of mesopores and increased pore diameter and pore volume by 128.7% and 656.3%, respectively, compared to sole LiFePO4. These significant improvements were related to the flexibility and ability of a thin layer of VFLG to limit the growth of LiFePO4 particles. This approach offers a promising strategy to enhance the thermal stability and surface properties of lithium-ion battery cathodes.

Abstract

Biotechnology is increasingly central to global innovation, with progress depending on effective collaboration between universities, industry, and policy frameworks. This study aims to examine institutional and policy drivers of university–industry collaboration (UIC) in biotechnology and identify models that accelerate commercialization and sustainable growth. Using qualitative comparative analysis (QCA) on four cases—SynbiCITE (UK), Bio Innovation Hub (Australia), Panjab University (India), and Oxford Science Enterprises (UK)—data were drawn from reports, policy documents, and innovation databases (WIPO, OECD, GEM). Results show that hybrid governance, flexible funding, transparent intellectual property (IP) frameworks, and targeted policy incentives shorten commercialization timelines, raise start-up survival above 65%, and boost joint patenting activity. University-linked venture capital provides patient capital and mentorship, while mission-driven R&D policies and balanced IP reforms enhance national alignment and innovation outputs. These findings suggest that integrated governance and policy strategies can foster competitive biotechnology ecosystems, and for emerging economies, adapting such models to local contexts offers pathways to accelerated innovation and long-term societal benefits.

Abstract

This research analyzes the implementation of Al-Islam Kemuhammadiyahan (AIK) and its impact on religious values at the Pimpinan Ranting Muhammadiyah (PRM) Yanggong, Jenangan, Ponorogo. The primary focus is identifying the forms of AIK implementation, evaluating its success in shaping the community's religiosity, and identifying the supporting and inhibiting factors of the process. This study is highly significant due to the limited in-depth research on the effectiveness of AIK at the branch level, especially in facing contemporary challenges such as shifts in community mindset and the strong influence of external culture. To achieve these objectives, the research employs a qualitative approach using a case study method at PRM Yanggong. Data collection involved in-depth interviews with key informants (the PRM Chairman, board members, and community leaders), participatory observation of religious and social activities, and the documentation of historical data. All collected data were then analyzed descriptively to gain a comprehensive understanding of AIK implementation. The research findings indicate that AIK implementation at PRM Yanggong is realized through a holistic approach, encompassing formal and non-formal education, dakwah (Islamic propagation), and communal religious practices. This approach has been significantly successful in building religious values, evidenced by enthusiastic participation in worship and the successful purification of aqidah (creed) from takhayul, bid'ah, and khurafat (TBC - superstition, innovation, and myth) in traditions like weddings and funerals. The main supporting factors are strong leadership and active community participation, though shifts in mindset and the penetration of external culture emerged as primary inhibitors.

Abstract

Nanokitosan adalah jenis polisakarida hasil turunan kitosan yang bersumber dari eksoskeleton arthropoda laut seperti krustasea (udang, lobster, kepiting, teritip, kril) serta kutikula serangga. Nanokitosan telah disetujui sebagai feed aditif oleh Badan Pengawas Makanan dan Obat-obatan Amerika Serikat tetapi masih jarang digunakan oleh para peternak lokal di Indonesia. Berdasarkan potensi tersebut dilakukan penelitian dengan tujuan menganalisis pengaruh kadar pemberian aditif pakan nanokitosan dalam pakan terhadap bobot badan dan somatometri itik pengging yang ditunjukkan dengan panjang badan, lingkar toraks, lingkar abdomen, panjang leher, paruh, sayap, tibia, dan tarsometatarsus. Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri atas 5 perlakuan meliputi P0 (pakan basal 100%), P0 adalah pakan basal tanpa aditif pakan nanokitosan (100% pakan basal); P1, P2, P3, dan P4 adalah pakan basal yang diberi aditif pakan nanokitosan, masing-masing dengan kadar 2,5; 5; 7,5; dan 10 g/kg pakan, tiap perlakuan diulang sebanyak lima kali. Pakan dan minum diberikan secara ad libitum. Data dianalisis menggunakan uji Kruskal Wallis. Berdasarkan hasil analisis penelitian disimpulkan bahwa nanokitosan sebagai aditif pakan dapat mempertahankan bobot badan dan ukuran somatometri pada itik pengging berdasarkan indikator yang diukur, meliputi panjang badan, lingkar toraks dan abdomen, panjang sayap, leher, paruh, tibia, dan tarsometatarsus. Penggunaan nanokitosan sebagai aditif pakan dapat diberikan pada itik pengging (Anas platyrhynchos) umur 4 minggu (fase starter) agar dapat diperoleh efek yang optimal terhadap proses pencernaan, metabolisme, dan performa produktivitas yang terkait dengan bobot badan dan ukuran somatometri pada itik pengging.

Abstract

Obesity can decrease the quality of life for those affected. The issue of obesity in female students is not only related to their physical condition but also affects their psychological well-being. Meanwhile, self-concept encompasses an individual's mental representation of themselves, including both physical and psychological aspects. The aim of this study is to understand the self-concept of female students experiencing obesity and the factors influencing it. This research employs a qualitative method with a phenomenological approach. Data were obtained through interviews with five female student subjects experiencing obesity. Subjects were selected using purposive sampling technique. The criteria for subjects in this study were active female students at the State Islamic Institute (IAIN) of Kediri, unmarried, with a body mass index (BMI) classification indicating obesity (BMI > 25.0 according to WHO). The results of this study are as follows: (1) The self-concept of female students experiencing obesity at the State Islamic Institute (IAIN) of Kediri is that they can describe their current physical and psychological conditions. Slimness is considered the beauty standard in their environment, although the subjects have their own beauty standards and make efforts to achieve them. Obesity does not hinder them in carrying out daily activities but affects their health. Female students experiencing obesity receive negative treatment and comments from their surroundings. They feel sad, regretful, self-blaming, and self-loathing about having an obese body. They also experience anxiety related to their health and lack confidence when looking in the mirror. In interactions, they may appear relaxed or embarrassed, but they still fulfill their daily roles effectively. (2) Factors influencing the self-concept of female students experiencing obesity include body shape, nicknames, unsuccessful weight loss attempts, and social support.

Abstract

Ayam petelur jantan merupakan ayam cull yang memiliki pertumbuhan efisien dan dijadikan sebagai produk substitusi ayam kampung. Daun kelor mengandung komponen nutrien esensial dan berpotensi dijadikan aditif pakan untuk pemacu pertumbuhan ayam petelur jantan. Penelitian ini bertujuan untuk menganalisis pertumbuhan ayam petelur jantan yang diberi tepung daun kelor sebagai aditif pakan. Penelitian menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 6 kali ulangan. Kelompok perlakuan terdiri atas kontrol (tanpa penambahan tepung daun kelor), serta kelompok aditif tepung daun kelor 1%, 2%, 3%, dan 4%. Variabel yang diukur meliputi konsumsi pakan, bobot tubuh mingguan, pertambahan bobot tubuh, dan rasio konversi pakan. Hasil penelitian menunjukkan bahwa aditif pakan tepung daun kelor tidak berpengaruh secara signifikan terhadap konsumsi pakan, bobot tubuh mingguan, pertambahan bobot tubuh, dan rasio konversi pakan pada ayam petelur jantan (P>0,05). Meskipun demikian, penggunaan tepung daun kelor sebagai aditif pakan sampai dengan dosis 4% tidak memberikan dampak negatif pada pertumbuhan ayam petelur jantan.
