Abstract

Disrupsi teknologi Kecerdasan Buatan (AI) menuntut transformasi fundamental dalam kepemimpinan pendidikan, dari peran manajerial menuju peran yang lebih adaptif dan beretika. Penelitian ini bertujuan untuk menganalisis bagaimana pemimpin pembelajaran di SMK Muhammadiyah 1 Baturetno, sebuah sekolah kejuruan di wilayah non-urban, memaknai dan mentransformasikan bermaksud untuk mengintegrasikan AI secara etis dan berkeadilan. Dengan menggunakan pendekatan kualitatif berdesain studi kasus, data dikumpulkan melalui wawancara mendalam, observasi partisipan, dan studi dokumentasi dengan kepala sekolah, wakil kepala sekolah, dan beberapa guru. Hasil penelitian menunjukkan bahwa transformasi peran terjadi melalui tiga tahapan utama: (1) pergeseran makna kepemimpinan dari 'manajer' menjadi 'arsitek ekosistem belajar'; (2) penerapan strategi 'koalisi-terbatas' untuk menavigasi resistensi dan memantik inovasi dari bawah; dan (3) munculnya kesadaran akan dilema antara mendorong inovasi dengan memastikan keadilan digital bagi siswa dari latar belakang sosial-ekonomi yang beragam. Temuan ini mengimplikasikan bahwa kepemimpinan yang efektif di era AI tidak hanya menuntut kecakapan teknis, tetapi juga kecerdasan emosional untuk mengelola perubahan dan kompas moral yang kuat untuk menempatkan keadilan sebagai inti dari kebijakan teknologi.

Abstract

Pengembangan biomaterial antibakteri yang berkelanjutan sangat penting untuk kemajuan bioteknologi lingkungan dan meningkatkan pengendalian patogen. Komposit hidrogel berbasis kitin menunjukkan aktivitas antimikroba alami. Namun, penentuan formulasi optimal masih menjadi tantangan akibat interaksi nonlinier antara kitin, PVA, gelatin, dan honey (madu). Studi ini memperkenalkan jaringan saraf tiruan Multilayer Perceptron (MLP) sebagai kerangka kerja prediktif dan optimasi cerdas untuk menentukan komposisi hidrogel paling efektif terhadap Pseudomonas aeruginosa. Model MLP dilatih menggunakan dataset sekunder dan dievaluasi melalui R², MSE, RMSE, dan MAE untuk menilai akurasi prediksi dan kinerja generalisasi. Model mencapai R² sebesar 0.991 pada tahap pelatihan dan 0.914 pada tahap pengujian, menunjukkan kemampuan yang baik dalam menangkap hubungan variabel yang kompleks. Kemudian, optimasi berbasis grid mengidentifikasi formulasi optimal yang terdiri dari 0.06 g/mL kitosan, 0.05 g/mL PVA, 0.00 g/mL gelatin, dan 0.01 g/mL honey (madu), menghasilkan zona inhibisi maksimum sebesar 30.66 mm. Selain itu, validasi eksternal menunjukkan bahwa model MLP menghasilkan bias rata-rata sebesar 4.80%, melampaui Response Surface Methodologydan mengonfirmasi kemampuannya yang superior dalam pemodelan nonlinier. Hasil ini menunjukkan potensi jaringan saraf MLP sebagai salah satu algoritma pemodelan untuk mempercepat penemuan dan optimasi hidrogel antibakteri ramah lingkungan dalam aplikasi bioteknologi lingkungan.

Abstract

A QCM (Quartz Crystal Microbalance) can be developed as a humidity sensor with a selective coating material. TiO2 (titanium dioxide) is a metal oxide with several crystal phases: anatase and rutile phases. However, there are few studies on the crystal phase investigation of a TiO2-based humidity sensor. Thus, this study aimed to develop a humidity sensor by functionalizing TiO2 particles with different crystal phases. The coating materials were prepared by ultrasonication. The synthesis was conducted by mixing 7 mL of TTIP (Titanium (IV) Isopropoxide) precursor in ethanol. This solution was stirred for 30 minutes, ultrasonicated, and heated for 16 hours to make a gel. The next step was a calcination process with two different temperatures to produce different crystal phases: 500oC (anatase) and 700oC (rutile). The synthesized powders were analyzed using XRD-SEM and coated onto the surfaces of the QCMs used as the developed sensors. These sensors were tested inside a chamber using a humidity control kit and a frequency counter (humidity levels: 57% to 92%). The results show that the rutile phase has a smaller particle diameter (252.672 nm) than the anatase phase (384.589 nm). The humidity sensing examinations indicate that the anatase-phase sensor has faster response-recovery times (19 seconds and 8 seconds) than the rutile-phase sensor (28 seconds and 50 seconds). It can be concluded that TiO2 particles in the anatase and rutile phases can be functionalized as a high-sensitivity coating material for a QCM humidity sensor.

Abstract

Traditional pastoral counseling often relies on intuition or spiritual experience without a systematic methodological foundation, making it difficult to measure intervention effectiveness and limiting accountability in service. This study aims to explore the importance of scientific thinking in pastoral counseling practice as a means of epistemological integration between psychology and spirituality, to produce reflective and responsible practice. The method employed includes a literature review on counseling theories, scientific epistemology, and pastoral practice, as well as conceptual analysis on the application of scientific methodology in assessment and counseling interventions. The results indicate that applying scientific thinking enables pastoral counselors to evaluate intervention effectiveness objectively, reduce subjective bias, and strengthen professional service. Integrating scientific approaches with spiritual values also allows counselors to facilitate clients’ holistic growth, uniting psychological, social, and spiritual aspects. Thus, an ideal pastoral counselor functions as both a spiritual guide and a reflective scholar grounded in validated data, theory, and experience.

Abstract

One area that requires attention in water quality studies is the estuarine ecosystem. Estuaries are transition zones connecting freshwater and marine waters, thus possessing unique environmental dynamics. However, there is limited information regarding the effect of sea tides in the area on local estuary water quality. Therefore, this study aims to identify the existing relationship between sea tide levels and EC values, using an IoT-based system that is portable, lightweight, and capable of operating in real time. This study was conducted over five days in Senggigi village, Batulayar, West Nusa Tenggara, Indonesia. The collected data focused on the EC parameter's water quality levels at different tide levels, which were monitored using the self-developed system. This system was developed using an EC sensor, a microcontroller, and a wireless internet router (for wireless data communication via ThingSpeak.com). This system was also equipped with a pH sensor, a TDS sensor, and a water temperature sensor. The recorded data show that the resulting data are valid and highly accurate, and that the system is ready for examination at the measurement area. The resulting data show that the correlation between tide level and EC value is logarithmic, with a regression coefficient of 0.934. The EC level was about 20.42 – 62.54 mS/cm, depending on the tide level. It can be concluded that the tide level indeed influences the EC parameter in the estuary area. Moreover, TDS plays an important role in regulating EC levels, underscoring the need to systematically measure this parameter in any estuarine water-quality study.

Abstract

Chitosan, a natural biopolymer, has attracted attention for its potential antibacterial properties against a wide range of pathogens. The escalating crisis of antibiotic resistance necessitates the exploration of novel antibacterial agents effective against both Gram-positive and Gram-negative bacteria. This study aimed to predict the antibacterial potential of chitosan against Staphylococcus aureus (a Gram-positive bacterium) and Escherichia coli (a Gram-negative bacterium) using a comprehensive in silico approach. Short chitosan oligomers, specifically trimers, were used to ensure computational feasibility and reliable molecular docking, as full-length polymers are too large for standard docking algorithms. Molecular docking simulations were performed using AutoDock to investigate the interactions between 13 chitosan compounds and the essential bacterial protein DNA gyrase, a key enzyme involved in DNA replication and repair. Binding affinities, interaction patterns (such as hydrogen bonding and hydrophobic contacts), and conformational changes were analyzed. The ligand showing the most favorable docking profile was further evaluated via molecular dynamics simulations using OpenMMDL to assess the stability of the complex over time. The results indicated that the chitosan derivatives, namely aminoethyl chitosan and dimethylaminoethyl chitosan, interact favorably with DNA gyrase in S. aureus and E. coli, respectively, with differential binding energies and interaction modes suggesting potential variations in inhibitory mechanisms between Gram-positive and Gram-negative bacteria. These computational findings support the potential of chitosan as a broad-spectrum antibacterial agent and provide a theoretical framework to guide further in vitro and in vivo validation of chitosan as a novel antibacterial compound.
