Abstract

Busuk buah rhizoctonia adalah salah satu penyakit pada tomat yang terjadi karena adanya serangan dari cendawan Rhizoctonia solani Kühn yang menyebabkan penurunan hasil buah tomat yang cukup signifikan dan mempengaruhi tinggi permintaan pasar, sehingga membutuhkan upaya pengendalian jamur yang dapat mengimbangi angka serangan penyakit. Secara teknis petani saat ini menggunakan pestisida sintetik untuk pengendalian penyakit pada tanaman budidaya yang dapat menimbulkan dampak negatif bagi lingkungan, sehingga dibutuhkan alternatif pengendalian dengan menggunakan pestisida nabati. Penelitian ini dilakukan untuk mengidentifikasi jamur penyebab penyakit, mengetahui pengaruh pemberian ekstrak daun salam, lengkuas dan kunyit terhadap jamur, serta menganalisis kombinasi terbaik ekstrak daun salam, lengkuas dan kunyit dengan konsentrasi 5% untuk mengendalikan jamur penyebab penyakit busuk buah Rhizoctonia pada tanaman tomat. Penelitian ini dilakukan di Laboratorium Ilmu Hama Penyakit Tumbuhan, Fakultas Pertanian, Universitas Mulawarman dari Januari  hingga April 2023. Hasil percobaan disusun dalam  Rancangan Acak Lengkap dengan 8 perlakuan dan diulang sebanyak 6 kali. Data yang diperoleh dianalisis dengan menggunakan sidik ragam (ANOVA) dan di uji lanjut menggunakan uji Beda Nyata Terkecil (BNT) pada taraf 5%. Penelitian ini menunjukan pemberian ekstrak daun salam, lengkuas dan kunyit memberikan aktivitas penghambatan pada pertumbuhan koloni jamur. Pemberian perlakuan kombinasi ekstrak daun salam, lengkus dan kunyit memiliki efektifitas terbaik dalam menghambat pertumbuhan koloni jamur uji dengan konsentrasi 5% ditunjukkan pada daya hambat sebesar 53,56%.

Abstract

Kutai Kartanegara (Kukar) Regency has the potential for vast land, a suitable climate, and the enthusiasm of local farmers as a major dragon fruit producing area in East Kalimantan, even nationally. Batuah Village, Loa Janan Sub-district, is one of the villages with a high number of dragon fruit producers managed by a joint farmer group. The development of dragon fruit is now starting to be constrained by problems in cultivation as well as pests and diseases. Pest attacks can reduce the quality and quantity of crop yields, thus becoming a limiting factor in dragon fruit production. This research aims to inventory pests on dragon fruit plants in Batuah Village. This research was conducted for approximately 1 month, starting from research preparation to final identification in 5 (five) different gardens in Batuah Village, Loa Janan District. Observations were made on dragon fruit plants that were attacked by diseases, pests and nematodes. Based on the results of the research conducted, it can be concluded that dragon fruit plants in Batuah Village are attacked by pests and diseases which are mostly caused by fungi, bacteria and fruit flies. But for bacteria can only be seen based on symptoms and signs, while the nematodes found are non-parasitic nematodes. Fungi that attack dragon fruit plants include Fusarium sp., Phytophthora sp., Pythium sp., Botryodiplodia sp., and Bipolaris sp. The most common fungus found in this study is Fusarium sp. Pests that are commonly found and damage dragon fruit are fruit fly larvae (Bactrocera sp). Non-parasitic nematodes found on dragon fruit plants in this study were Rhabditis sp., Dorylaimus sp., and Aphelenchus sp.

Abstract

The study entitled Persistence of the virus that causes mosaic disease in chili seeds originating from the production of chili plants that are attacked by a virus that is treated by soaking at some temperature aims to see the persistence or presence of the virus that causes the mosaic. The persistence of the virus is done by observing the chilli seedlings that are 8 weeks after planting. The research was carried out at the Plant Pest and Disease Laboratory, Faculty of Agriculture, Mulawarman University, Samarinda. The study was conducted using the observation method that is directly observing the treatment carried out. This study used 5 treatments and each of 4 replications, consisting of: C1 = treatment of warm water with a temperature of 40 ° C for 10 minutes, C2 = treatment of warm water with a temperature of 45 ° C for 10 minutes, C3 = treatment of warm water with a temperature 50 ° C for 10 minutes, C4 = treatment of warm water with a temperature of 55 ° C for 10 minutes, Cs = treatment of warm water with a temperature of 60 ° C for 10 minutes. The results showed that soaking warm water had an influence on the persistence of viruses carried in the seeds to the development of mosaic disease in chilies. Temperatures of 50 ° C and above have been able to prevent mosaics disease at chillie plant.

Abstract

The research was conducted to determine: endophyte fungi on paddy plant (Oryza sativa); the antagonistic percentageof endophyte fungi against to Pyricularia oryzae Cav.; and the antagonistic mechanisms between each endophyte fungi to Pyricularia oryzae Cav..The experiment was conducted at the Integrated Laboratory of Agriculture Faculty of Mulawarman University, and samples of infected plant was collected from Sungai Kapih village, Sambutan Sub-district of Samarinda City The experimental treatments was arranged in a Completely Randomized Design (CRD), consisting of four treatments and each treatment was repeated ten times.The results showed that endophyte fungi isolated from the paddy plant (Oryza sativa) were Trichoderma sp., Rhizopus sp., Gliocladium sp., and Penicillium sp. The competition was proved as the antagonistic mechanism of Rhizopus sp. against, while antibiosis was proved as the antagonistic mechanism of Penicillium sp. against. Trichoderma sp. and Gliocladium sp. against were shown to have two antagonistic mecanism are competition and parasitsm. The capability of endophyte fungi as a biological agents to compete those P. Oryzae was express an antagonism capacity differences, the highest rate of inhibition was occurred on the P. oryzae vs Gliocladium sp.(78,96%).
