Abstract

The objective of this research is to assess the impact of PGPR, Trichocompost, and MOL on the growth and quality of production, as well as the incidence of disease-causing microorganisms in tomato plants. This study will be conducted by comparing the use of beneficial organic microorganisms namely PGPR, Trichocompost, and MOL with inorganic farming systems that utilize synthetic fertilizers and manure as sources of nutrition for tomato plants. The research method employed a randomized block design consisting of three treatments as follows: Treatment A involved a combination of PGPR, Trichocompost, and MOL; Treatment B utilized inorganic fertilizers N, P, K along with foliar fertilizers Gandasil D and B; Treatment C consisted of chicken manure. Each treatment was replicated five times, with 50 plants per plot, resulting in a total of 750 plants for observation. The results indicated that the application of PGPR, Trichocompost, and MOL positively influenced the average flowering time, the average weight of 50 fruits, and the duration until fruit decay during the growth, development, and production phases of tomato plants. Furthermore, the use of PGPR, Trichocompost, and MOL effectively reduced the incidence of the fungal pathogen P. palmivora on leaves, the bacterial disease Erwinia sp. on leaves, and the fungal disease P. palmivora on fruit stems.

Abstract

The purpose of this study is to determine the types and populations of pests in cabbage plants planted intercropping with mustard greens in Kakaskasen I Village, Tomohon City. The research method used is a survey method on experimental land made without the use of pesticides. Data collection was carried out on 3 observation plots with the number of sample plants in each plot was 30 plants. Observation of pest types and populations on cabbage plants is carried out every 2 weeks from the age of cabbage plants 2 weeks after planting to harvest. The data obtained were analyzed descriptively about the types and populations of pests in cabbage plants. The results of this study found that the main pests that attack cabbage plants that are planted intercropped with mustard greens are Plutella xylostella and Crocidolomia binotalis. The population of P. xylostella pests in cabbage plants is low on average ranging from 0.002 to 0.067 larvae/plant, while the population of C. binotalis pests is high with an average range of 0.056 to 1,422 larvae per plant. It is necessary to preserve the parasitoid D. semiclausum to control the pest of P. xylostella and find environmentally friendly pest control solutions of C. binotalis to produce healthy cabbage production.

Tujuan dari penelitian ini adalah untuk mengetahui jenis dan populasi hama pada tanaman kubis yang ditanam tumpangsari dengan refugia sawi hijau di Desa Kakaskasen I Kota Tomohon.  Metode penelitian yang digunakan adalah metode survei pada lahan percobaan yang dibuat tanpa menggunakan pestisida.  Pengambilan data dilakukan pada 3 plot pengamatan dengan jumlah tanaman sampel masing-masing plot adalah 30 tanaman.  Pengamatan jenis dan populasi hama pada tanaman kubis dilakukan setiap 2 minggu sekali sejak tanaman kubis berumur 2 minggu setelah tanam sampai panen. Data yang diperoleh dianalisa secara deskriptif tentang jenis dan populasi hama pada tanaman kubis. Hasil penelitian ini ditemukan hama utama yang menyerang tanaman kubis yang ditanam tumpang sari dengan refugia sawi hijau adalah hama Plutella xylostella dan Crocidolomia binotalis.   Populasi hama P. xylostella pada tanaman kubis rendah berkisar rata-rata 0.002 – 0.067 larva/tanaman, sedangkan populasi hama C. binotalis tinggi dengan rata-rata berkisar 0.056 sampai 1.422 larva per tanaman.  Perlu melestarikan parasitoid D. semiclausum untuk mengendalikan hama P. xylostella dan mencari solusi pengendalian hama C. binotalis yang ramah lingkungan untuk menghasilkan produksi kubis yang sehat.

Abstract

Eco-enzyme (EE) liquids produced by fermenting fruit waste may provide low-cost, locally available odor sources for fruit-fly monitoring. This study evaluated the effectiveness of EE baits prepared from nutmeg, banana, and pineapple wastes, as well as a mixed formulation, for trapping Bactrocera spp. in chili (Capsicum frutescens L.) fields in Kakaskasen I Village, Tomohon City, Indonesia. The experiment used a randomized complete block design with four EE treatments and five replicates. Traps were installed in fruiting-stage chili plots at approximately 1.5 m above ground level with ~5 m spacing and were observed over four sampling rounds at 6-day intervals. Captured adult fruit flies were counted and identified morphologically, and treatment effects were analyzed using analysis of variance followed by an LSD (BNT) test at the 5% significance level. Two species were recorded, Bactrocera dorsalis and B. cucurbitae. Mean trap catches (adults per trap) were highest for pineapple EE (6.3), followed by mixed EE (3.1), nutmeg EE (1.7), and banana EE (1.3). Pineapple EE differed significantly from the other treatments (LSD5% = 3.7), whereas the remaining treatments did not differ significantly. Captures were reported to be predominantly female, and non-target insects were also collected, indicating limited selectivity. Overall, pineapple fruit-waste EE showed the strongest field performance and warrants further development as a practical bait for Bactrocera spp. monitoring in chili agroecosystems.
