Abstract

Begonia is one of the world's largest genera of flowering plants that spread in various tropical and subtropical regions worldwide. However, deforestation, overexploitation, climate change, and pathogen-causing diseases have threatened the diversity of begonia. Diseases on begonia need to be handled seriously because the level of spread and damage can result in the death of the plant. Thus, this study was conducted to identify the main pathogens causing diseases in the begonia which is expected to be basic information in determining the effective control treatment. As a result, begonia collections of Eka Karya Bali Botanic Garden were mainly infected by three pathogenic fungi (Fusarium spp., Oidium begoniae, and Botrytis cinerea) and one bacterium (Xanthomonas begoniae).

Abstract

Agriculture is an important sector in Indonesia. Farming are how most people make a living within the population [1]. Currently, access to consult with agricultural experts is something that farmers don't have as a privilege. The combination of technology and agriculture needs to be developed to make it easier for farmers to consult. Botani Mobile Apps is an Android-based application that has been developed by the Faculty of Agriculture UB. The purpose of this application is to facilitate farmers in agricultural cultivation. User experience is how a person feels when using a product, system, or service [2]. User experience evaluation needs to be done to measure the success of a product design and to get user feedback for further improvement. One method of evaluating user experience is UEQ (User Experience Questionnaire). Evaluation of user experience of the Botanical mobile application using UEQ will be discussed in this study. Based on the results of the UEQ that have been carried out, the 26 questions asked had an average value of more than 1. After grouping the questions on the 6 UEQ Scale, the average results of calculation showed that all scales are in the green area. Based on UEQ characteristics, the highest scores were Attractiveness, Pragmatic and Hedonic qualities, respectively. All the results of the characteristic values were more than 1. Based on the Benchmark calculation, showed that the Attractiveness, Efficiency, Dependability and Novelty scales had good scale results and the Perspicuity and Novelty scales got above average scale results. Based on all the results of the UEQ evaluation, it can be concluded that the user experience on the BOTANI application is good.

Abstract

Farmers' utilization of pesticides in Indonesia is very high because pesticides are the main method for farmers to control pests and diseases. This research was conducted to determine farmers' level of knowledge of the use of pesticides. The research method used in this research was quantitative, using survey methods. The survey method was used to obtain factual information by exploring the level of knowledge, attitudes and actions of farmers related to pesticides. Sampling was conducted in Tulungrejo Village, Ngantang District, Malang Regency, with 50 farmers as respondents. The results of this study found that most of the respondents know about pesticides and the types of pesticides. The primary factor influencing pesticide use selection was the characteristics of farmers. The farmer age in Tulungrejo Village is 56%, and the farmer is 30-50 years old. Most of them had a low educational level, and 48% of the farmers only finished elementary school. However, the respondents needed to learn that the use of pesticides should be the last step in controlling pests and diseases, according to Integrated Pest Management (IPM). Therefore, an education and training program on IPM and pesticide use should be planned to assist farmers in improving their knowledge and skills.

Abstract

Soil is a habitat for many types of microbes that have a role in maintaining soil nutrition, and most of them grow around plant roots. Factors that are quite influential in the growth process are the hormone auxin, which has a role in stem bending and stimulates differentiation. This study aimed to obtain a genus of IAA hormone-producing rhizosphere fungi (Indole-3-Acetic Acid) and determine the effect of environmentally friendly and conventional land cultivation on the diversity of IAA hormone-producing fungi at Agrotechnopark UB Cangar Garden. Fungi isolates were cultured on Potato Dextrose Agar (PDA) and Potato Dextrose Broth (PDB) media enriched with tryptophan as a precursor to form IAA. IAA measurements were carried out qualitatively by adding the Salkowski reagent and quantitatively by measuring the absorbance. As many as 10 rhizosphere fungal isolates were obtained from environmentally friendly land and 8 fungal isolates from conventional land, which produced IAA hormones. The fungal genera obtained included Acremonium, Aspergillus, Colletotrichum, Fusarium, Penicillium, and Trichoderma. Environmentally friendly cabbage fields (average: 283.8 ppm) showed higher yields than conventional fields (average: 140.9 ppm) in producing IAA hormones. There was a correlation between soil pH and organic matter on fungal diversity, with a correlation value of 0.878. The diversity index value of rhizosphere fungi was 1.359; the evenness index was 0.845, and the dominance index was 0.302 on environmentally friendly land. The diversity index value of rhizosphere fungi was 1.213; the evenness index was 0.875, and the dominance index was 0.344 on conventional land.
