Abstract

Rice plants typically grow in paddy fields, but they can also be cultivated in dryland areas, known as upland rice. This study aims to examine the effect of applying the micronutrient boron on the growth and morphological characteristics of two rice varieties, IPB 3S and IPB 9G, conducted at the Leuwikopo experimental field of IPB using the legowo planting system. The treatments consisted of four combinations: no boron application on IPB 9G and IPB 3S varieties, and boron application on both varieties. Boron was applied at a concentration of 20 ppm through foliar spraying on the lower leaf surface three times during the growing period. Observations were made on plant characteristics, including leaf shape and position, plant height, number of tillers, flowering age, panicle exertion, and grain characteristics. Based on the results, it can be concluded that rice grain filling is influenced by pollen production and viability, which can increase the percentage of filled seeds and seed production. However, the production results in this study could not be analyzed due to bird pest attacks, which resulted in the absence of harvest data. Therefore, further research is recommended with more optimal plant protection to accurately obtain seed production data.

Abstract

West Bangka Regency has significant potential from its local avocado accession, Muhfud, which has been cultivated and adapted to local agroecological conditions for decades. However, this accession has not been registered as a variety, rendering it vulnerable to genetic erosion and misappropriation. This study aimed to characterize the morphological traits of Muhfud avocado accession from West Bangka Regency as a step toward preserving local germplasm. Qualitative and quantitative morphological observations were performed on vegetative, generative, and fruit traits. The study was conducted from August to October 2025, employing purposive sampling on five trees, including the original parent tree. Characterization followed the descriptor for avocado, encompassing tree organs, leaves, flowers, fruits, and seeds. The results indicate that Muhfud accession exhibits distinctive morphological features, such as a semi-circular tree architecture, type B flowering, a clavate fruit shape with buttery-smooth, doughy texture, and fruits that are longer with thinner skin compared to other local varieties such as Muntok accession. Variations in mean values and standard deviations of quantitative morphological characters (particularly fruit weight of 358.40 ± 29.04 g, tree height of 5.90 ± 2.32 m, and stem circumference of 70.12 ± 26.67 cm for Muhfud accession) suggest strong genetic potential and adaptation to the local agroecological conditions of West Bangka Regency. These characteristics support the development of locally adapted, productive, and storage-resilient superior varieties. In conclusion, the findings contribute to germplasm conservation efforts and the advancement of local avocado breeding programs in tropical Indonesia.

Abstract

Perkembangan teknologi rekayasa optik telah membawa perubahan signifikan dalam sistem penilaian mutu benih, melalui penerapan metode non-destruktif seperti Biospeckle Laser Imaging (BLI). Kajian ini bertujuan untuk mereview secara sistematis publikasi ilmiah terpilih dalam 10 tahun terakhir yang membahas aplikasi BLI, pencitraan multispektral dan hiperspektral, serta Optical Coherence Tomography (OCT), evaluasi kesehatan dan kualitas benih. Artikel dianalisis berdasarkan relevansi dengan topik, kebaaruan metode, dan fokus pada metode non-destruktif berbasis optik. Hasil analisis menunjukkan bahwa BLI mampu mendeteksi aktivitas metabolik, viabilitas, vigor, dan infeksi patogen pada berbagai jenis benih dengan tingkat akurasi yang sangat tinggi, mencapai lebih dari 90%. Keunggulan utama teknik ini meliputi efisiensi waktu, sifat non-destruktif, serta ramah lingkungan dibandingkan metode konvensional. Selain itu, integrasi teknik optik dengan algoritma machine learning dan deep learning terbukti mampu meningkatkan akurasi klasifikasi dan efisiensi diagnosis, seperti pada deteksi kontaminasi aflatoksin, kerusakan mekanis, dan identifikasi varietas benih. Namun, implementasi teknologi ini di tingkat lokal masih menghadapi tantangan berupa keterbatasan infrastruktur, rendahnya literasi teknologi, serta kebutuhan akan perangkat portabel dan protokol standar yang mudah diadopsi. Secara keseluruhan, pendekatan rekayasa optik berbasis BLI dan teknik pencitraan lainnya berpotensi besar menjadi standar baru dalam sistem penjaminan mutu benih yang presisi, efisien, dan ramah lingkungan. Rekomendasi utama diarahkan pada penguatan kolaborasi lintas sektor untuk mempercepat adopsi teknologi ini dalam mendukung pertanian presisi dan ketahanan pangan nasional.

Abstract

This study explores the knowledge, attitudes, and practices of farmers in Bangka Regency, Indonesia, regarding the management of diseases affecting horticultural crops. Field surveys and structured interviews were conducted across nine villages to assess the incidence of plant diseases and the control methods employed by local farmers. The results showed an average disease incidence of 23.33%, with the highest observed in cucumber crops at 66%. Most farmers (75%) practiced monoculture farming, which contributed to the persistence and spread of soil-borne diseases such as Fusarium wilt and root rot. Synthetic pesticides were the predominant control method, with 68% of farmers applying them regularly, and many exceeding recommended dosages. Although most respondents could visually identify disease symptoms, their understanding of disease development stages, causal agents, and sustainable control options was limited. Notably, none of the farmers were familiar with biological control agents and only a minority believed that organic materials could reduce disease incidence. The findings underscore a heavy dependence on chemical control and highlight a significant gap in awareness of integrated and environmentally friendly disease management practices. Factors such as improper pesticide use, poor seed quality, and suboptimal soil conditions further exacerbated disease risks. To enhance productivity and sustainability, it is critical to strengthen farmers' capacity through education and training in integrated disease management, emphasizing crop rotation, balanced fertilization, and the adoption of biological control strategies. These interventions are essential for reducing losses and promoting sustainable horticultural production in Bangka Regency.
