Abstract

Ralstonia solanacearum (Smith) is one of soil borne pathogens causes bacterial wilt diseases and R. solanacearum is difficult to control because it has a long survival in the soil and have many hosts alternatives. One alternative to control R. solanacearum and to increase productivity is by using grating with combination of resistant varieties of tomato as a rootstock and high production varieties of tomato as a scion. Several studies on grafting to suppress R. solanacearum were reported. However, study on grafting with combination between resistant tomato varieties (Amelia H7996) and high-production tomato varieties with R. solanacearum infestation and without R. solanacearum infestation on the component of yield and fruit quality is limited. The study aims to analyze the effect of grafting with R. solanacearum infestation to the intensity of bacterial wilt disease, component of yield, and fruit quality with R. solanacearum infestation and without R. solanacearum infestation. The result indicated that the intensity of bacterial wilt disease on grafted tomato did not significantly different from resistant rootstock but significantly different from scion. Infestation of R. solanacearum on grafted tomato can decreased the plant productivity that decreased the component of yield on grafted tomato. R. solanacearum infestation also decreased the fruit quality on diameters and fruit firmness. Nevertheless, R. solanacearum did not affect the Total soluble solid/TSS (°Brix). TSS on grafted tomato indicated that the value is taller than rootstock in the field with R. solanacearum infestation and in the field without R. solanacearum infestation. Keywords: fruit quality, productivity, Rasltonia solanacearum, tomato grafted

Abstract

Effect of Pseudomonas fluorescens P60 on pathological and physiological quality and growth of rice IR 64 seedlings. The research objectives were (1) detection and identification of seed-borne pathogens of IR 64 rice, (2) testing Pseudomonas fluorescents P60 in inhibiting the in vitro growth of seed-borne pathogens colonies, (3) testing P. fluorescents P60 for pathological and physiological seed quality, and (4) testing P. fluorescents P60 on the growth of seedlings in the greenhouse. The results showed that some seed-borne pathogens can be found both on farmers’ IR 64 rice and factory’s; they were Aspergillus flavus, Alternaria padwickii, Pseudomonas glumae, and P. syringae. Application of P. flourescens P60 was able to inhibit the in vitrogrowth of colonies of all seed-borne pathogens, except P. syringae. Related to pathological quality, the effect of P. flourescens P60 on percentage of seed-borne pathogens attack did not significantly different from that of benomil but smaller than distilled water. On the physiological quality of seeds, treatment of P. flourescens P60 has the same effect with benomil and distilled water, with germination rate was more than 80%. In the greenhouse study,treatment of seed immersion time in P. flourescens P60 suspension showed that the effect of immersion time as long as15 minutes and 25 minutes on seedling height, root length, and seedling dry weightdid not significantly different. were. However, 25 minutes immersion time resulted in fresh seedling weight and root dry weight higher than that of 15 minutes immersion time.

Abstract

Oil palm empty fruit bunches (EFB) is the largest solid waste palm oil production. The waste pollutes the environment and waste management (EFB) has been carried out with burnt, aggravating environmental pollution. This resulted in the need for environmentally-friendly waste management. One of them uses microbes that can degrade components of the waste so that the waste can be used as compost EFB and natural mulch for agriculture. Use of microbes to degrade the waste components EFB potentially produces enzymes that accelerate the degradation lignoselulolitik EFB waste components. This research aims to study the biodegradation by a mixture of isolates of Aspergillus sp., Trichoderma sp. and Actinomycetes with the addition of some nitrogen as a nutrient source for growth microbes. The results showed that the addition of a mixture of isolates with the addition amoniumsulfat and chicken manure as a source of N can lower C / N ratio of 10 and 51.9 % of fragility, as well as lower levels of cellulose, hemicellulose and lignin respectively 66 %, 36.4 % and 40.7 % of the initial levels. These results indicate that the addition of N sources of natural and synthetic amoniumsulfat chicken manure as well as accelerate the degradation of fungal isolates TKKS into compost

Abstract

Ralstonia solanacearum (Smith) is a soil-borne pathogen that causes bacterial wilt disease and is a complex species in races, biovars, phylotypes, and strains of various pathogenicities. As a result, the pathogen is difficult to control. An alternative control is by applying actinomycetes and bacteriophages on tomato grafted with resistant rootstock. This study aims to find the best combination in controlling bacterial wilt disease among grafted tomato plants and/or actinomycetes and/or bacteriophage treatments to increase yields. The graftings were between Amelia (East West, Indonesia) or H7996 (AVRDC) as rootstocks, and Servo (East West, Indonesia) as the susceptible scion. The grafting used the tube method, and the experimental design was a randomized completely block design with the grafted plants treated by actinomycetes and/or bacteriophages with three replications. The results indicated that actinomycetes application on plants grafted with Amelia rootstock or H7996 and the application of bacteriophages on susceptible varieties (Servo) could be the best alternative treatment in controlling the bacterial wilt disease. The susceptible varieties with the actinomycetes or bacteriophages application could even increase fruit yields higher than the grafted tomatoes treated with actinomycetes or bacteriophages. In fact, the susceptible tomato varieties with bacteriophage treatment showed high fruit yield. Keywords: actinomycetes, bacteriophages, bacterial wilt disease, fruit yield, Ralstonia solanacearum

Abstract

Bujangseta is a technology used throughout the year to produce citrus fruits. This technology has economically succeeded in increasing the income of citrus farmers by 23.5%. Sustainable management of bujangseta technology is neede, one of which is maintaining the sustainability of the agroecosystem. A stable agroecosystem ensures the availability of ecosystem services through nutrient cycling and the natural control of pest and disease populations. The stability of agroecosystems is coherent with the high biodiversity of arthropods. This study aims to evaluate the effect of applying the citrus plant bujangseta in Karangwidoro village and Krajan village, Dau District, Malang Regency, East Java, from June to December 2022. The two application methods were light trapping (lighttrap) and pit trap (pitfall glass), and the results were analyzed using a t-test. The diversity index, species richness index, species evenness index, and dominance index were calculated. The results showed that the detrivores of the Collembola group dominated the diversity of arthropods, the primary pest of the Diaphorina citri, and the predatory arthropods of Paederus sp. and Braconidae. Diversity and community structure of arthopods indicated there at significant differences in diversity, dominance, evenness, and species richness in those two locations. Bujangseta in the Krajan has a higher community structure compared to the Karangwidoro, showing that the ecosystem at the Krajan location is better preserved. Keywords: arthropods, bujangseta, citrus, community structure

Abstract

Fertilizer is a substance that provides nutrients for plants. Deficiency of fertilizer results in stunted plant growth and development. Therefore with the condition of the scarcity of chemical fertilizers that occurs in Indonesia decrease of productivity. This is impact in the government's efforts to promote the pro-organic movement. One of the pro-organic movement is learning through field schools (SL) about integrated pro-organic technology in rice cultivation. Integrated pro-organic technology thaat includes the use of organic fertilizer, biological agents/local microorganisms, botanical pesticides and biosaka. This SL activity is carried out as a form of community service in overcoming the problem of scarcity and farmers' dependence on chemical fertilizers. Besides that, integrated pro-organic technology is also expected to be able to maintain the stability of rice plant productivity. The aim of this community service is to maintain the productivity of rice plants with integrated pro-organic technology. This activity was implemented in 10 farmer groups in Jetis District, Ponorogo Regency. The method used is learning and practice through field schools about integrated pro-organic technology which includes organic fertilizer, biological agents/local microorganisms, vegetable pesticides, and Biosaka. Furthermore, rice cultivation using integrated pro-organic technology in 10 farmer groups. The results of the application of integrated pro organic technology showed that integrated pro organic technology is able to maintain and increase the productivity of rice plants by 7.49 tonnes/ha compared to rice cultivation without pro organic technology of 7.22 tonnes/ha. These results increase the enthusiasm of farmer groups in carrying out pro-organic cultivation in the midst of a scarcity of fertilizer

Abstract

Latar belakang: Pemanfaatan bahan-bahan alami sebagai pestisida dalam upaya penanganan hama kutu daun pada cabai merah menjadi salah satu alternatif yang perlu untuk dikembangkan. Daun sirih merupakan tanaman yang potensial untuk dijadikan pestisida nabati karna memiliki kandungan kimia dengan sifat antimikroba dan insektisida alami seperti minyak atsiri dan beberapa kandungan lainnya. Namun pemanfaatan daun sirih sebagai pestisida nabati oleh petani di Desa Kayu kebek masih minim dikarenakan petani belum memiliki pengetahuan dan keterampilan dalam pembuatan pestisida nabati daun sirih. Penelitian ini bertujuan untuk melakukan penyuluhan dan menganalisis perubahan perilaku petani di Desa Kayukebek terhadap pemanfaatan daun sirih sebagai pestisida nabati dalam menangani hama kutu daun pada tanaman cabai merah. Metode: Metode penelitian ini menggunakan mix method (metode kualitatif dan Kuantitatif) yang dilaksanakan pada bulan januari sampai dengan bulan Mei 2024. Penyuluhan dilaksanakan dengan menggunakan pendekatan secara individu yakni anjangsana serta pendekatan kelompok yakni pertemuan kelompok, kaji terap dan kunjungan lapang.Sampel penelitian ini sebanyak 20 petani yang tergabung dalam kelompok tani Taman Madani. Analisis data dilakukan secara deskriptif kualitatif dan kuantitatif untuk mengukur dan mengetahui perubahan tingkat pengetahuan, sikap dan keterampilan petani. Hasil: Hasil analisis data menunjukan bahwa terdapat peningkatan pengetahuan petani sebesar 44% yang diketahui dari nilai pre test 47% meningkat menjadi 91% pada nilai post test. Sedangkan perubahan tingkat sikap sebesar 87% pada kategori bertanggung jawab dan tingkat keterampilan sebesar 93% pada kategori problem solving.
