Abstract

Cauliflower (Brassica oleracea var. botrytis L.) during its development period needs to be controlled by pests and diseases, because at that time the flowers or krobs come out and will determine the quality and quantity of its production. This research is conducted to characterize and differentiate various types of pests and diseases found in cauliflower plants in the gardens of Gonaman Village, Koripan, Matesih District, Karanganyar. This research employs a methodology based on descriptive qualitative analysis. The tools utilized in this study include a mobile phone, writing instruments, and observation sheets. The research subjects consist of various pests and diseases identified in the garden area. Data collection by observation of the garden and direct interviews with garden owners. For data analysis and validation, qualitative descriptive techniques are used with additional interview activities with cauliflower farmers and literature studies. Based on the results of the study, eight pests have been found, namely; Whitefly / Cabuk (Aphis brassicae), Thrips (Thrips tabasi), Whitefly (Aleyrodidae sp), Crop Caterpillar (Crocidolomia binotalis), Ladybug (Illeis galbula), Brown grasshopper (Valanga nigricornis), Leaf beetle (Aluacphora sp), Leaf caterpillar (Plutella xylostella). And four diseases were found; Alternaria brassicae fungus, bacterial rot by Pectobacterium carotovorum, Erwinnia carotovora bacteria, and Xanthomonas camprestis bacteria. The visible symptoms are damage to the leaves, yellow, brownish to blackish leaves, rotten and wilted flowers so that they can reduce the harvest. Pest and disease control can be done by spraying pesticides, fungicides once a week, maintaining land cleanliness, maintaining planting distance, selecting healthy seeds, and providing lime and boren. For further research, it should be done for several days, in the morning and evening when insects are active.

Abstract

Biodiversity learning in senior high schools (SMA) is often less than optimal due to a lack of local context. Tawangmangu boasts a diverse range of banana varieties in its traditional markets, which offer potential as a biology learning resource in line with the existing curriculum. This study aims to identify and analyze the diversity of local banana varieties in Tawangamngu Tourist Market and develop biology learning resources for high school biodiversity. Sampling was conducted using a purposive-random method across all market stalls. Morphological identification was conducted systematically, including visual documentation, measurements of quantitative (fruit length, diameter, number of clusters) and qualitative (skin color, fruit shape, flesh texture, aroma) parameters, and interviews with vendors to obtain ethnobotanical information. Data were verified with taxonomic literature and then analyzed through triangulation of morphological observations, ethnobotanical interviews, and literature references. The research identified 17 banana varieties with the AA, AAA, AAB, ABB, and BB genome groups, including Bawen, Raja Bulu, Susu, Cavendish, Raja Sereh, Raja Uli, Raja Mas, Ambon Lumut, Ambon Kuning, Tanduk, Kepok Kuning, Kepok Putih, Mas Kirana, Nangka, Klutuk, and Kembung. Each variety has distinctive morphological characteristics and different uses. The diversity of local bananas at Tawangmangu Tourist Market can be used as an effective learning resource for high school biodiversity materials, bridging theoretical concepts with students' real-world environments, in accordance with the Independent Curriculum framework.
