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.

Abstract

Increase of sugarcane productivity must be followed by improvements to a more environmentally sound cultivation system. One of them is the use of endophytes. Endophytic fungi are indeed included in the group of growth-promoting fungi or Plant Growth Promoting Fungi / PGPF and are known to secrete growth hormones such as Indole Acetic Acid (IAA), gibberellin so that they can spur growth. This study aims to determine the type of endophytic fungus that can potentially be PGPF in sugarcane breeding. The research uses sampling methods, exploration, and application of PGPF in sugarcane plants. The results of the identification of endophytic exploration fungi of sugarcane plants obtained five colonies consisting of 4 genera and four species from Trichoderma sp., Aspergillus sp., Penicillium sp., and Fusarium sp. From the results of the potency test, the results were obtained that the soaking of bud set seeds with isolates of the fungus Trichoderma sp., Penicillium sp. Noticeable effect on plant height, stem diameter, and the number of leaves.

Abstract

Pekarangan secara umum memiliki fungsi sosial budaya, hubungan ekonomi, serta biofisika. Pekarangan memiliki manfaat sebagai penghasil tanaman untuk kebutuhan pangan, rempah, buah, biofarmaka, dan hewan ternak. Penelitian ini bertujuan untuk mengetahui pemanfaatan tanaman pekarangan oleh masyarakat Desa Pagung, Kecamatan Semen, Kabupaten Kediri.  Metode yang digunakan dalam penelitian ini adalah metode survei lapang dimana kegiatan meliputi wawancara, identifikasi jenis tanaman dan analisis data. Pengumpulan data dilakukan  dengan cara wawancara semi terstruktur dengan responden. Setelah pengumpulan data, dilanjutkan pengumpulan spesimen tumbuhan yang didampingi oleh informan kunci. Analisis data dilakukan secara deskriptif kualitatif. Hasil penelitian didapatkan kategori pekarangan Desa Pagung tergolong pekarangan dengan luas sedang yang ditanami 53 spesies tanaman buah yang berasal dari 22 famili. Tanaman buah yang sering  ditemui di pekarangan Desa Pagung adalah Pisang (Musa paradisiaca) sekitar 15,55% dan Mangga (Mangifera indica) sekitar 14,50%. Masyarakat Desa Pagung menanam tanaman buah karena hobi, karena pemeliharaan budidaya yang mudah, vegetasi untuk lahan yang erosi atau longsor, koleksi, peneduh, ketersediaan air yang sulit. Tanaman buah yang dibudidayakan oleh masyarakat Desa Pagung selain dikonsumsi dalam bentuk buah juga dimanfaatkan sebagai obat (22,64%), ritual budaya atau agama (15,09%), peneduh (22,64%), dan hias (3,77%).
