Formula with active ingridient of fluorescent pseudomonads and its influence on wilt disease development of pepper.The purpose of this study was to synergize organic fertilizer with biopesticides of fluorescent pseudomonads 122 to be the best formula to increase the resistance of pepper plants to wilt disease. The study used a completely randomized design (CRD), which consisted of four treatments. The treatments were forms of active ingredient formula of fluorescent pseudomonads (powder, pellet, granule, and liquid). The effectiveness of the formula in suppressing development of the disease was measured by observing the incubation period, index of the disease and discoloration of vascular tissue of pepper. The results showed that the disease incubation period of plant treated with liquid and powder formula was longer than formula with granule and pellet. Plants treated with powder formula showed the lowest disease index compared to control, liquid, pellet and granule formula. Disease index and discoloration in vascular tissue was also of the lowest value when the plants were treated with powder formula. This result indicate that active ingredient of fluorescent pseudomonads formulated in powder was the most effective to inhibit the development of wilt disease on pepper caused by Fusarium sp. and Ralstonia solanacearum. ABSTRAK Formula berbahan aktif pseudomonad fluoresen dan pengaruhnya terhadap perkembangan penyakit layu pada cabai.Tujuan penelitian ini untuk mensinergikan pupuk organik dengan biopestisida pseudomonad fluoresen 122 menjadi formula terbaik untuk meningkatkan ketahanan tanaman cabai terhadap penyakit layu. Penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri dari empat perlakuan. Keempat perlakuan tersebut adalah bentuk formula dengan bahan aktif pseudomonad fluoresen yaitu formula serbuk, pelet, granul, dan cair. Keefektifan formula dalam menekan perkembangan penyakit, diukur dengan mengamati masa inkubasi, indeks penyakit dan perubahan warna jaringan pembuluh pada tanaman cabai. Hasil penelitian menunjukkan bahwa pada pengamatan masa inkubasi yang diperlakukan dengan formula cair dan serbuk terlihat lebih lama dibandingkan formula granul dan pelet. Adapun hasil pengamatan terhadap indeks penyakit yang diperlakukan dengan formula serbuk menunjukkan hasil yang paling rendah dibandingkan dengan kontrol, cair, pelet dan granul. Sampai akhir pengamatan indeks penyakit dan panjang perubahan warna pada jaringan pembuluh, dengan pemberian formula serbuk menunjukkan nilai paling rendah. Keadaan tersebut menunjukkan bahwa perlakuan dengan pemberian formula berbahan aktif serbuk paling mampu menghambat perkembangan penyakit layu pada cabai yang disebabkan oleh Fusarium sp. dan Ralstonia solanacearum.Kata kunci: cabai, penyakit layu, pseudomonad fluorescen
Introduction of biofertilizer containing pseudomonad fluorescent isolate Pf-122 as active ingredient for improving growth and production of chili plant in the field.Some biological control agents required an efficient formulation required to be apply on large scale in the field. The purpose of this research is to review some biofertilizer formulations form of active ingredients pseudomonad fluorescent Pf-122 which can increase growth and production chilli in the field. The research using Randomized Complete Block Design (RCBD) which consists three kinds of formulation. The formulations are powder, granules and pellets. Chilli without formulations as a control. The best results was growth and production of chilli can be showed from plant height, branch number, productive branch number, fruit number, and fruit weight which was given powder formulation. The results of fruit number, the powder formulation which is given can produce double chilli yield than yield from control plant. Moreover, weight fruit from chilli which is given powder formulation can produce fourfold yields. Growth and production chilli which is given others formulations such as granules and pellets were not significantly different results. The overall result of this research, the best formulation to increase growth and production of chilli in the field was formulations contain active biopesticide pseudomonad fluorescent Pf-122 in powder.
The purpose of the study is to explain the important impact of using mural art as a destination branding to promote Kampong Opak Gambir in Plosokerep Village, Blitar City. This study uses a qualitative research method with a phenomenological approach. This study aims to reveal the structure of the subject's awareness in relation to the phenomenon of destination branding using murals. Data collection techniques used surveys with questionnaires and used interviews with village officials, community leaders, local creative economy actors, women's groups, and youth organizations. The researchers realized the expectations of the subjects, based on the results of field observations, responses from questionnaires, and interviews (15 informants) by changing the appearance of the village through mural art in several locations chosen by villagers. This study found that the collective identity of the residents of Plosokerep Village agreed to give the name Kampong Opak Gambir as a destination branding. Meanwhile, mural artworks strengthen destination branding, because they beautify tourist spots to increase the attractiveness of tourist objects and the number of tourist visits. Determination and strengthening of destination branding through a construction process among local government actors, local economic actors, and local tourism actors through collective activities involving elements of cognition, affection, and social relations within the village community and externally with the city government and investors.
Green fleas or Coccus viridis (Homopterа: Coccidae) is one of the pests of coffee plants. Pest control efforts can be carred out by using environmentally friendly botanical pesticides. Vegetable pesticides are pesticides whose main ingredients come from plants. The purpose of this study was to determine the effect of giving pesticides from tobacco plants, brotowali plants, and a mixture of the two, with different concentrations on the level of damage to green tick pests on Robusta coffee plants in Dompyong Village, Bendungan District, Trenggalek Regency. This research was carried out in vivo and in vitro. In vivo testing using the RAK method or Factorial Randomized Block Design and then for in vitro testing using the non-factorial RAL method. For in vivo testing there are 6 levels of treatment, each treatment has 4 replications. In vitro testing was carried out in the laboratory with 5 levels of treatment and there were 4 replications. The application of botanical pesticides has a significant effect on the intensity of pest attacks, the number of pest populations, and the mortality of green lice. The result of this study is that the most effective composition of botanical pesticides to reduce pest attacks on coffee plants in Dompyong village, Bendungan district, Trenggalek district is to use a composition of vegetable pesticides made from tobacco plants. For the concentration of botanical pesticides that are effective in reducing the level of damage to coffee plants caused by green lice is a concentration of 200 ml/l with an average mortality value of 20.00.
