This study aims to analyze the mechanical and thermal properties of water hyacinth fiber-based composite materials as an alternative to environmentally friendly packaging materials. This composite material is produced by mixing water hyacinth fiber with a natural polymer matrix that can decompose easily. Manufacturing methods include mixing, pressing, and thermal treatment processes. The mechanical properties of composite materials, including tensile strength and resistance to deformation, are tested using tensile tests and hardness tests. Thermal analysis is carried out through thermogravimetric tests (TGA) to identify the thermal stability and decomposition of the material. The results showed that the water hyacinth fiber-based composite materials had fairly good mechanical properties in certain mixture compositions, although they were not as strong as composite materials using synthetic fibers. However, this material shows potential in packaging applications that do not require extreme mechanical strength. The mechanical properties of the water hyacinth fiber composite produced lead to the fulfillment of the need for use as packaging, which is light, flexible and not easily broken. The thermal properties of the composites show faster decomposition compared to synthetic fiber based composites, but are still within the acceptable range for single-use packaging. With its environmentally friendly properties, this composite material can be an attractive alternative to reduce the use of plastic in the packaging industry. Nonetheless, improvements in manufacturing processes and material formulations are still required to improve their mechanical and thermal properties and maintain packaging durability under diverse usage conditions.

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.

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.

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.
