Pemanfaatan Kompos Ela Sagu, Sekam dan Dedak sebagai Media Perbanyakan Agens Hayati Trichoderma Harzianum Rifai.

The use of biological agents to prevent the growth of plant diseases is aimed at decreasing the capability of particular pathogen, preventing their growth and spread, reducing the infection and intensity of pathogenic attack to main plants. Trichoderma harzianum is commonly found in almost all types of soil, and is one of fungi that can be used as biological agents to control plant pathogens. Growth and development of this fungi are mostly influenced by factors such as temperature, light, air, and pH. It is also dependents on other nutrients such as carbon, nitrogen and plain carbohydrate which are contained in sago waste (ela), bran and rice husk. The objective of this study is to find out the utilization of sago waste, bran and rice husk as media to multiply the biological agents T. harzianum. The result of this study showed that sago waste compost could be used as a medium to multiply the antagonist T. harzianum; when appropriately mixed with bran and rice husk (1:1:1 v/v), sago waste composts would be an effective media to develop the T. harzianum fungus. This mixture is better compared to sago waste composts, husk, sago waste composts and bran, and sago waste composts and husk. It is doe to the fact that in the media number of spore of T. harzianum (7,08 x 109/mL) increased and colony characteristics was dense.

Control of Damping Off and Increased Growth of Tomato Seeds by Utilizing Trichoderma Harzianum Based on Solid Organic Materials

Low soil fertility and the presence of damping off disease which is a inhibiting factor in the nursery of tomato plants. This can be overcome by utilizing the biological agent Trichoderma harzianum based on solid organic matter (Trichocompost). The aim of the study was to determine the effect of giving Trichocompost and obtain the optimal Trichocompos dose to reduce the intensity of damping off disease and increase the growth of tomato seedlings. The treatments tried were Trichocompos with doses of 20, 40 and 60 tons/ha, designed using a complete randomized design with 10 replications. The plant response observed was the intensity of the disease; height, fresh weight and dry weight of canopy; length, fresh weight and root dry weight. The results showed that the monitoring of Trichocompost can reduce the intensity of damping off disease to 54.80% and increase the growth of tomato seedlings. The recommended Trichocompos dosage is 60 tons/ha or as much as 30 g/1 kg of soil. The results of this study can be used to increase agricultural production and also a solution in an environmentally friendly and sustainable farming system

Aplikasi Pupuk Hayati Konsorsium dan Inokulan Padat Trichoderma Harzianum terhadap Produktivitas Tanaman Sawi pada Lahan Terkontaminasi Rhizoctonia Solani

Choy sum (Brassica rapa L.) cultivation main obstacle in Maluku was soil fertility and plant diseases. Biological agent and Biofertilizers will play a significant role to reduce the intensity of disease attacks, and increase crop productivity. The objective of this experiment was to study the effects of nitrogen fixing and phosphate solubilizing microbe (Bion-UP) and Trichoderma harzianum solid inokulan (Bokelas Plus) on choy sum productivity grown on land Rhizoctonia solani-contaminated land. The experimental treatments were liquid biofertilizer and Bokelas Plus which has been combined into 6 treatments: Without biofertilizer and Bokelas Plus, 50 kg Bokelas Plus/ha without biofertilizer, 15 mL biofertilizer per plant without Bokales Plus, 15 mL biofertilizer per plant + 50 Kg Bokelas Plus/ha, 15 mL biofertilizer per plant + 25 kg Bokelas Plus/ha, and 7.5 mL biofertilizer per plant + 50 kg Bokales Plus/ha. The results showed that giving of Bokelas Plus and biofertilizer with different dose levels decreased leaf blight intensity and increasing fresh weight of choy sum. Biofertilizer application with and without Bokelas Plus decreased the intensity of leaf blight disease by 39.14% - 46, 93%, and increase the fresh weight of choy sum by 15.19% - 36.25%

PENGENALAN SUMBERDAYA MOLUSKA DAN EKOSISTEM LAMUN SERTA PENGENALAN MIKROPLASTIK DAN DAMPAKNYA BAGI LINGKUNGAN PESISIR BAGI SISWA SISWI SDN NEGERI LAMA KECAMATAN TELUK BAGUALA KOTA AMBON

Teluk Ambon dalam dengan tingkat pemanfaatan sumberdaya dan aktivitas kegiatan di laut yang tinggi mengakibatkan teluk Ambon banyak mendapat tekanan. Sumberdaya moluksa dan lamun merupakan sumberdaya yang ada di pesisir teluk Ambon. Isu mengenai polusi lautan oleh partikel mikroplastik telah membuka mata banyak orang tentang potensi bahaya yang mengincar biota laut dan manusia akibat pembuangan  sampah plastik ke laut secara sembarangan. Metode yang digunakan dalam kegiatan penyuluhan ini yaitu metode tahapan pendidikan, yaitu metode yang dilakukan melalui penyampaian materi melalui metode penyuluhan. Hasil dari pengabdian kepada masyarakat  (PKM) ini adalah Pengenalan sumberdaya moluska dan ekosistem lamun serta mengenal mikroplastik dan dampak bagi lingkungan pesisi
