Abstract

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is a new pest on maize that has successfully spread to various regions in Indonesia. This pest can cause severe damage to the affected plants. Most farmers have relied on synthetic insecticides for control. This research was conducted to determine susceptibility level of S. frugiperda larvae to emamectin benzoate, chlorantraniliprole, and spinetoram insecticides by using the diet-dipping method. There is no registered insecticide to control S. frugiperda, so the three types of insecticides used were based on the recommendation of the Ministry of Agriculture of the Republic of Indonesia. Five field-collected population from Central Java and a laboratory populations of S. frugiperda were used to develop a baseline susceptibility for each insecticide. First instar larvae of S. frugiperda were placed in vials containing artificial diet treated with insecticides and an untreated control (treated with water only), observed for mortality on the seventh day and data was analyzed using probit. S. frugiperda from Tegowanu was the most susceptible to emamectin benzoate (LC50 = 0.11 mg/L), while the least susceptible population was from Wedi (LC50 = 0.39 mg/L) with the resistance ratio (RR) values of 0.45-folds and 1.60-folds compared to the laboratory population, respectively. S. frugiperda from Ngombol was the most susceptible population to chlorantraniliprole (LC50 = 12.63 mg/L), while the least susceptible population was from Tegowanu (LC50 = 30.29 mg/L) with RR values of 0.90- and 2.15-fold compared to the laboratory population, respectively. Meanwhile, S. frugiperda from Jogonalan was the most susceptible to spinetoram (LC50 = 2.75 mg/L), while the population from Wedi was the least susceptible (LC50 = 5.94 mg/L) with the RR values of 0.52- and 1.12-fold compared to the laboratory population. Field-collected S. frugiperda populations were still susceptible to the three tested insecticides tested and emamectin benzoate being the most toxic compared to spinetoram and chlorantraniliprole.

Abstract

Visual documentation is an essential part of the data collection process in scientific research. Documentation can help data become more understandable and unambiguous. An effective visualization can strengthen the credibility of the data, facilitate readers' or audiences' understanding of the research context, and support the validity of field or laboratory observations. Based on initial observations and informal interviews with several final-year students, it was found that most lacked basic photography skills, especially in scientific documentation. Therefore, a photography technique coaching clinic was conducted by the Community Service Team, the Agrotechnology Student Association of Palangka Raya University, and the Indonesian Phytopathology Association of Central Kalimantan Regional Command. The aim was to improve students' knowledge and skills in scientific documentation photography. The method used was blended learning (theory and direct practice), along with pre-test and post-test questionnaires. The training results showed a significant increase in participants' understanding of basic photography techniques. Knowledge of photo composition increased to 87.8%, the use of light and shooting angles to 96.9%, optimal use of photographic equipment to 90.3%, and the preparation of visual documentation in research reports to 86.2%. This indicates that participants no longer view photography as merely a supplement but as an integral part of the process of recording data, analyzing, and presenting results scientifically and communicatively.
