Abstract

Semut rangrang (Oecophylla smaragdina) merupakan salah satu spesies semut yang memiliki perilaku sosial kompleks dan berperan penting dalam ekosistem. Studi mengenai karakteristik perilaku makan semut ini menjadi krusial dalam memahami dinamika interaksi mereka dengan lingkungan, termasuk pola pencarian dan konsumsi makanan. Tujuan penelitian ini adalah untuk mendeskripsikan karakteristik perilaku semut rangrang (O. smaragdina) yang hidup di habitat pohon sawo kecik (Manilkara kauki). Penelitian ini menggunakan metode ad libitum sampling yaitu mengamati seluruh aktivitas perilaku makan semut di habitat pohon sawo kecik, yang terlihat tanpa batasan tertentu berdasarkan fakta lapangan. Hasil penelitian menunjukkan bahwa ditemukan karakteristik perilaku semut dalam mencari dan memakan makanan mulai dari semut melihat umpan, mendekati umpan makanan (jangkrik), naik ke sarang untuk memanggil koloni, koloni turun untuk mendekati umpan makanan (jangkrik), koloni mengerubungi jangkrik, mematahkan kaki jangkrik, menghisap cairan tubuh jangkrik, melepas tali yang mengikat jangkrik, membawa kaki jangkrik ke sarangnya, membawa tubuh jangkrik ke sarangnya. Pengetahuan ini tidak hanya memperkaya literatur ilmiah tentang ekologi dan etologi semut, tetapi juga dapat digunakan sebagai dasar bagi penelitian lain yang berkaitan dengan interaksi semut dengan lingkungan mereka, peran semut dalam ekosistem, serta aplikasi praktis dalam pengendalian hama dan pengelolaan lingkungan.

Abstract

The tomato (Solanum lycopersicum), is a very valuable horticultural plant that is extensively grown in Jepron Village, Karangbangun District, Karanganyar Regency. However, pests and diseases frequently limit tomato yield. Finding the kinds of pests and illnesses that target tomato plants in the region is the goal of this study. Direct field observation and laboratory identification are two components of the qualitative descriptive research methodology. The study's findings found a number of pests, including armyworms (Helicoverpa armigera), fruit flies (Bactrocera sp.), and earthworms (Phytothetora infestans). Furthermore, brown spots (Alternaria solani), root rot (Ralstonia solanacearum), and leaf rot (Phytophthora infestans) were discovered. In order to increase harvest yields, this study suggests using environmentally friendly farming technologies and implementing integrated pest management (IPM) strategies. It is anticipated that the findings of this study will serve as a guide for managing pests and diseases to enhance the well-being of nearby farmers.

Abstract

Cashew (Anacardium occidentale) is one of the export commodities with high economic value. However, cashew production in Indonesia faces serious challenges due to pest attacks that can reduce yields. This study aims to identify the types of pests that attack cashew trees in Jatisari Village, Jatisrono District, Wonogiri Regency, and to analyze the relationship between pest occurrence and environmental factors such as temperature, humidity, and rainfall. The method used in this study was direct observation in four hamlets with data collection through visual documentation and recording symptoms of pest attacks on plants. The results showed that there were 11 main pest species that attacked cashew, including Bemisia tabaci, Hyphantria cunea, Sanurus indecora Jacobi, Toxoptera citricidus Kirk., Helopeltis sp., Setothosea asigna, Orgyia definita, Euthalia aconthea, and Melanitis leda. These pests cause various forms of damage to plants, such as defoliation, flower and fruit drop, and stunted growth. Environmental factors such as temperature and humidity have been shown to have a significant impact on the level of pest infestation. This study provides insight for farmers in more effective and sustainable pest control efforts.
