Abstract

The increase in demand for sweet potatoes was not accompanied by an increase in production caused by a reduction in the area planted with sweet potatoes due to land conversion from wetlands to marginal lands. However, the available land for the expansion of agricultural areas is dominated by acid soils that are poor in nutrients. The main problem of planting in acid soil is the high content of Aluminum (Al). One of the effective approaches to selecting plants that are resistant to Al is using the solution culture method by adding Al and adjusting the pH of the solution. This activity aimed to obtain and develop the most appropriate and efficient screening method for selecting the resistance of some sweet potato germplasm to Al stress. The plant materials used were several collections of sweet potato germplasm, namely: Antin 1, Antin 3, Beta 1, Beta 2, Kidal, Papua Salosa, Sari, and Sarwentar. The research activities included: (1) Screening of sweet potato shoots in Al solution culture media in the form of AlCl3.6H2O with concentrations of 0, 100, 200, 300, 400, and 500 mg/L with a solution pH of 4.0 and (2) Testing of sweet potato Al tolerant on acid soils, namely yellow red podzolic soil from Bagoang Jasinga Village, Bogor Regency, Indonesia with a pH of 4.4-5.2. The results obtained were two sweet potato varieties that were tolerant of Al and acid soils, namely Kidal and Papua Salosa. Both of these varieties can be used as Al-tolerant and acid-soil-tolerant sweet potato planting material. Meanwhile, Antin was used as a comparison plant material that was intolerant of Al and acid soil.

Abstract

Talas (Colocasia esculenta L. Schott) merupakan salah satu tanaman pangan tropis dengan nilai gizi tinggi yang berperan penting dalam ketahanan pangan lokal maupun global. Namun, produktivitas tanaman ini sering terhambat oleh keterbatasan bibit berkualitas, rentan terhadap serangan patogen, serta siklus perbanyakan vegetatif yang relatif lambat. Teknik kultur jaringan, khususnya melalui induksi dan regenerasi secara in vitro, menawarkan solusi untuk menghasilkan planlet talas dalam jumlah besar dan seragam. Zat pengatur tumbuh (ZPT) berperan krusial dalam mengarahkan proses morfogenesis, baik pada tahap induksi kalus maupun regenerasi planlet. Penelitian ini bertujuan untuk mengkaji efektivitas berbagai kombinasi ZPT, yaitu NAA, BAP, dan kinetin dalam menginduksi tunas dan regenerasi planlet talas. Metode penelitian melibatkan kultur eksplan talas pada media Murashige dan Skoog (MS) dengan variasi konsentrasi ZPT. Kombinasi ZPT terbaik adalah BAP 1,0 mg/L + NAA 0,5 mg/L menghasilkan waktu induksi tunas tercepat dan jumlah tunas terbanyak. Perlakuan media MS yang hanya diberi NAA tunggal terbukti paling efektif untuk induksi perakaran, dengan konsentrasi terbaik untuk induksi perakaran adalah 1,0 mg/L. Penelitian ini diharapkan memberikan kontribusi terhadap pengembangan teknik perbanyakan massal talas yang efisien, mendukung konservasi plasma nutfah, serta meningkatkan produktivitas pertanian.

Abstract

Tanah Sareal District is an urban area with a high level of urbanization and land conversion, potentially reducing the presence of conservation-value vegetation. This study aims to identify, analyze, and map the distribution of urban vegetation with conservation value using a Geographic Information System (GIS)-based spatial approach. The research method uses a descriptive quantitative approach through field surveys, Landsat 8 and Sentinel-2 image analysis, Normalized Difference Vegetation Index (NDVI) analysis, and overlay techniques, kernel density, and vegetation fragmentation analysis. The results show that more than two-thirds of the area is dominated by built-up areas, while high-density vegetation (NDVI > 0.5) is only found in limited areas such as river banks, green open spaces, and educational areas. The identified conservation-value vegetation includes Tanjung (Mimusops elengi), Kecapi (Sandoricum koetjape), Beringin (Ficus benjamina), Bisbul (Diospyros blancoi), and Pulai (Alstonia scholaris), with a fragmented distribution pattern. This study shows that GIS-based digital mapping effectively supports vegetation conservation planning and strengthens green open spaces in urban areas.

Abstract

This study investigated the integration of Artificial Intelligence based digital media into Argumentation Driven Inquiry learning activities to enhance vocational high school students’ critical thinking and problem-solving skills in Jakarta. The research employed a mixed-methods design involving two vocational schools (SMK PGRI 16 and 20). Data was collected through pre- and post-assessments, classroom observations, and structured interviews with students, teachers, and parents. Digital media included adaptive AI-powered learning modules and interactive simulations designed to foster curiosity and collaborative argumentation. Quantitative results showed significant improvements in students' Critical Thinking Skills, with an average increase of 23% between the pre- and post-tests, whileqQualitative findings revealed that AI-based digital media improved motivation, fostered deeper engagement with IPAS concepts, and supported self-directed learning. Despite the positive outlook, challenges included limited infrastructure and uneven digital literacy among students. Overall, the integration of AI-driven digital media in ADI-based learning offers a promising pathway to strengthen Higher order Thinking Skills in vocational education
