Synthetic pesticides are widely applied for pest and disease control in Indonesia. However, a lack of knowledge and use of Good Agricultural Practices (GAP) for safe pesticide usage among Indonesian farmers remains a problem. This study aims to investigate the gap between farmers' knowledge of GAP for safe pesticide usage and their application of it. This research was conducted in 2020 in five Indonesian provinces. Primary data collection was by means of a survey, in which 298 respondents answered structured questionnaires. The survey also identified the sources of the information recorded and the respondents' experience of pesticide exposure. The analysis tools used were the Wilcoxon Signed Ranked Test and Importance-Performance Analysis (IPA). There were significant differences in the results of the first analysis. These results appear to confirm the results of further analysis using IPA, which show that a high level of knowledge does not mean that farmers will apply this knowledge in practice: this is particularly relevant to wearing gloves and masks, using tools to remove blockages, never clearing blocked nozzles by blowing into them, and disposing of empty containers properly. Nevertheless, in some cases high levels of knowledge do result in high levels of application. Cases of pesticide exposure affecting human health by causing symptoms such as dizziness, nausea, and vomiting confirm that GAP for pesticide usage are not being implemented properly by some farmers. It is therefore recommended that their knowledge should be enhanced through the series of technical training programs using participatory approaches, so that farmers accumulate knowledge which will drive them to adopt GAP for safe pesticide usage.
Abstract. Rubiyo, Dewi YA, Imran, Salim A, Baharudin, Indrawanto C, Ratule MT. 2020. Evaluation of yield and pest and disease resistance of cocoa clones in Kolaka District, Southeast Sulawesi, Indonesia. Biodiversitas 21: 5698-5607. Cocoa is one of the main plantation commodities in Indonesia. It is an important source of foreign exchange and employment. Currently, Indonesian cocoa production and productivity, including in Southeast Sulawesi, are declining due to pests and diseases. In addition, there is a lack of high-quality and high-yielding clones. This study aimed to evaluate the quality of cocoa clones and resistance to cocoa pod borer (CPB) and cocoa pod rot (CPR) disease caused by the fungus Phytophthora palmivora. The study tested 12 cocoa clones, which included four high-yielding clones. The research location was in Lambandia Subdistrict, Kolaka District, Southeast Sulawesi Province, Indonesia. Clonal planting material was propagated by grafting in 2010. The study used a randomized block design and the treatments consisted of 20 plants of each cocoa clone with three replications. The clones were evaluated from 2018 to 2019. The observed variables included resistance to CPB and CPR. The results of the study based on the quality component showed that the clones MT, M04, and M01 had the highest average weight per one dry bean of 1.55 g, 1.64 g, and 1.24 g, respectively. Beans produced by clones MT, M01, and M04 had an average fat content of 53.36%, 52.72%, and 50.76%, respectively. Observations of the average number of pods with CPR showed that the lowest rate of attack (about 6%) was in BAL 209 and PT. Ladongi clones, with attack intensities of 20% and 18%, respectively; therefore, these clones were classified as resistant to CPR. Evaluation of the level of resistance to attack by CPB pests found two resistant clones, PT. Ladongi and Sulawesi 2, with light levels of attack on beans.
In Solok District, West Sumatra Province, farmers plant curly red chilies using the local variety Sukarami with simple cultivation technology. The resulting productivity is around 6-7 tonnes /ha. The Indonesian Agency for Agricultural Research and Development (IAARD) has introduced cultivation technology for red chilies namely ‘Proliga’ to increase productivity. The experiment was conducted in Sukarami Field Station in Solok Regency. Four treatments with Six replication have been applied, (1) Proliga cultivation technology using Kopay Variety (Proliga Kopay), (2) Proliga cultivation technology using Kencana Variety (Proliga Kencana), (3) Proliga cultivation technology using Sukarami Variety (Proliga Sukarami), (4) Farmer’s cultivation technology using Sukarami Local Variety. The results show that the application of Proliga technology increases the yield. The largest increases were obtained through the application of Proliga technology using Sukarami local variety, with a revenue value of Rp. 209,448 million / ha or an increase of 57.44% compared to the Farmer’s cultivation technology using Sukarami Local Variety. The R/C and MBCR values of the Proliga Sukarami technology are 1.51 and 2.36 respectively.
