PHYSIOLOGY CHARACTER of Bacillus Spp As BIOSTIMULANT PROMOTING OF PLANT GROWTH
No full textThe purpose of this research to know the physiologically character of Bacillus spp. rhizobacteria of potato var. Hartapel as promoting to plant growth. Rhizosbacteria was isolated and tested for producing ACC deaminase, IAA, GA, fixing nitrogen, dissolving phosphate, producing siderophores and hydrogen cyanide. Bacterial isolates Bacillus niabensis Strain PT-32-1, Bacillus subtilis Strain SWI16b, Bacillus subtilis Strain HPC21, Bacillus mojavensis Strain JCEN3, Bacillus cereus Strain HY, and Bacillus moyavensis UCMB 5075 are non-pathogenic thermotolerant. The consortium of bacterial isolates Bacillus subtilis Strain SWI16b with Bacillus subtilis Strain HPC21 are synergistic non pathogenic and have the most complete characters that can stimulant the growth and development in vitro of potato crops. These bacterial isolates can be used as active ingredients for biostimulant formulation to promote plant growth

Full text linkAbstractThis research aims to analyze the diversity of fruit flies (Bactrocera sp.) and their damage to tomato plantings. The research was carried out in Ouw village, East Saparua District, Central Maluku Regency. This research was a quantitative descriptive study carried out using a survey method with ME traps, which were applied directly in the field using Steiner Trap Type II traps. Data analysis includes the Diversity Index, Relative Density, Evenness Index, Dominance Index, and Damage Intensity. According to the study's findings, Bactrocera dorsalis, Bactrocera umbrosa, and Bactrocera cucurbitae were the fruit fly species that were discovered in tomato plantings. The Diversity Index (H') value is 0.7253, which indicates a low level of diversity; the highest Abundance Index (KR) is B. dorsalis with a value of 62.4633%; the Evenness Index (E) is 0.6602 in the even category; and the Dominance Index (D) is 0.4365 in the medium dominance category with a Damage Intensity of 9.76 percent, which is classified as light criteria

Full text linkThe research aims to identify the types of natural enemy insects of cocoa fruit borer pests and analyze the diversity index and calculate the index of dominance of natural enemy insects in cocoa cultivation (Theobroma cacao L.) in Mamala and Hila Villages, Leihitu district, Central Maluku regency. Random sample method with sampling techniques with certain criteria (cocoa plants that have borne fruit). Each village was taken 3 farmers then each farmer determined 3 sample plots with a plot size of 20 x 20 m2 then determined 3 sample crops. Insect catching uses 4 traps namely sweep net, pit fall traps, yellow traps, and leaf traps. The dataanalyzed in the form of qualitative data is the type of insects found and quantitative data, namely the diversity index and the dominance index. Based on the results of the study obtained the results of the study obtained 5 orders and 9 Families that have the potential as natural enemies, namely the Order Hymenoptera, Dermaptera, Ortopthera, Diptera and Ordo Coleoptera while the Families found are the Family Formicidae, Chelisochidae, Carcinophoridae, Forficulidae, Mantidae, Dolichopodidae, Stratiomydae, Coccinelidae, and the Family Chrysomelidae. The natural enemy diversity index in mamala village cocoa plantation (0.0771) and Hila (0.0884) is low and the dominance index in Mamala (0.97600557) and Hila (0.97362747) is hig

No full textThe Effectiveness of Leaf Powders from Several Types of Plants as Botanical Insecticides Against Mung Bean Beetle Pest (Callosobruchus chinensis L.) in Storage
Full text linkMung bean (Vigna radiata L.) has the third economic value among the legume group in Indonesia, after soybeans and peanuts. In storage, mung beans are often attacked by the beetle pest Callosobruchus chinensis L.; thus, it is necessary to control these pests. One way to control it is by using botanical insecticides derived from several types of plants, including lime leaf powder, noni leaf powder, nutmeg leaf powder, and lemongrass leaf powder. The purpose of this study was to obtain the most effective type of plant powder in controlling C. chinensis pests on mung bean seeds in storage. The study was conducted at the Plant Pest Laboratory of the Faculty of Agriculture, Pattimura University, which took place from November 2020 to January 2021. The study was conducted using a Completely Randomized Design with 4 treatments, namely DJ (15 g of lime leaf powder per 100 g of mung bean seeds), DM (15 g of noni leaf powder per 100 g of green bean seeds), DP (15 g of nutmeg leaf powder per 100 g of green bean seeds), DS (15 g of lemongrass leaf powder per 100 g of green bean seeds) and K (control, without leaf powder). Twenty imagos of C. chinensis were used in each treatment, and the experiment had 3 replicates. The variables observed included the initial symptoms after treatment, the mortality rate of the test insects, and the mortality of the test insects. The results showed that the DS (lemongrass leaf powder) and DM (noni leaf powder) treatments resulted in the mortality of the test insects of 93.33% and 91.67%, respectively, and were more effective than the other two treatments, namely DP (nutmeg leaf powder) and DJ (lime leaf powder) as well as controls.

Full text linkPenelitian ini bertujuan untuk mendapatkan jenis media yang efektif digunakan dalam perbanyakan masal jamur M.anisopliae di Laboratorium dan mendapatkan data lama waktu simpan untuk menjaga kualitas M. anisopliae tetap dalam kondisi baik. Penelitian dilaksanakan di Balai Besar Perbenihan dan Proteksi Tanaman Perkebunan (BBPPTP) Ambon dan Laboratorium Penyakit Fakultas Pertanian Universitas Pattimura Ambon pada bulan Agustus - November 2023. Rancangan Acak Lengkap digunakan dengan 4 perlakuan yaitu menggunakan media PDA, SDA, jagung dan beras yang diulang sebanyak 3 kali. Parameter yang diamati yaitu morfologi koloni M. anisopliae pada setiap media meliputi warna, tekstur, elevasi dan bentuk koloni; diameter pertumbuhan yang dilihat secara visual; dan jumlah kerapatan spora yang dihitung pada minggu ke 1, 2, 3, dan 8 pada setiap media. Hasil penelitian menunjukan bahwa media terbaik untuk perbanyakan jamur M. anispleae di laboratorium yaitu media jagung diikuti dan media SDA dengan kerapatan spora pada minggu ke 3 masing- masing 20 x dan 16 x .Media dengan daya simpan terbaik sampai minggu ke 8 yaitu media jagung dan media SDA dengan kerapatan spora masing-masing 17,67 x dan 14,00 x

Full text linkUpaya peningkatan produktivitas terung seringkali terkendala kerusakan tanaman oleh serangan fitopatogen dan hama. Pemanfaatan metabolit sekunder agens hayati untuk pengendalian fitopatogen dan hama perusak pada tanaman, merupakan cara pengendalian yang ramah lingkungan. Penelitian ini bertujuan untuk mendapatkan konsentrasi metabolit sekunder Trichoderma harzianum yang efektif untuk mengendalikan penyakit busuk buah Phomopsis vexans dan hama perusak daun Epilachna, serta untuk meningkatkan produksi terung. Perlakuan yang dicobakan adalah metabolit sekunder T. harzianum dengan konsentrasi 0%, 10%, 20% dan 30%. Hasil penelitian menunjukkan bahwa perlakuan metabolit sekunder T. harzianum menekan penyakit busuk buah Phomopsis, tetapi tidak berpengaruh terhadap kerusakan daun Epilachna. Pengobatan dengan konsentrasi 10%, 20% dan 30% masing-masing dapat menurunkan intensitas penyakit 51.65%, 64.25% dan 69.63%. Kerusakan daun oleh Epilachna sp tergolong ringan untuk semua tingkat konsentrasi yakni berkisar 3.65-4.32%. Perlakuan metabolit sekunder T. harzianum dengan berbagai tingkat konsentrasi berpengaruh terhadap panjang buah tetapi terhadap jumlah buah, diameter buah, dan berat buah tidak berpengaru
