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

This study explores the social interaction behaviors of domestic pigeons (Columba livia domestica) during the matchmaking period. The aim is to understand how multi-channel communication through body movements, vocalizations, and tactile contact affects the formation of pair bonds. This research employed an observational method at the Green House of Universitas Veteran Bangun Nusantara using the ad libitum sampling technique to record daily behaviors of pigeons kept in a confined space. The results revealed that male pigeons predominantly initiate interactions, while females exhibit selective responses that determine mating success. Characteristic behaviors such as bowing, cooing, billing, and allopreening were observed to follow a sequential pattern from orientation and approach to attraction and acceptance. These findings suggest that the intensity and consistency of social interactions significantly contribute to successful pair bonding in domestic pigeons. Future research may investigate hormonal or neurological aspects that underlie these social behaviors.

Abstract

Long photoperiods can delay flower initiation and slow down the formation of flower primordia, so they can delay flowering. This study aims todetermine the photoperiodism response of four o'clock flowers (Mirabilis jalapa L.) to the short length of irradiation. The research was carried out for 3months (April-June 2024) and specifically data collection was carried out on 8 June 2024 in Bulurejo village, RT.03 RW. 04, Karangmojo, Weru District,Sukoharjo Regency, Central Java. From 05.53 WIB to 17.30 WIB. Samples of 15 plants growing in Bulurejo village, observed when the flowers bloom. Datawere analysed descriptively qualitative and combined with literature studies. The results of research on 15 plants of four o'clock flower (Mirabilis jalapa L.),the same species and location of four o'clock flower blooming turned out to be different times even though the difference was only slight. The average time ittakes to bloom is 10 hours 42 minutes. Further research needs to be done with a variety of different flowers, not only red flowers, but plus white, red andmixed colours with varied village locations, especially at differentaltitudes.Four o'clock flower (Mirabilis jalapa L) is a member of the family Nyctaginaceae, order Centrospermae, and is easy to grow in the yard withoutmuch care.
