Abstract

Trichoderma is a soil saprophytic fungus that is naturally parasitic and attacks many types of plant disease-causing fungi or has a broad spectrum of control. This study aims to obtain superior isolates of the antagonist fungus Trichoderma sp from several plantations. This study used a non-factorial completely randomized design consisting of seven treatments with three replications. The treatments tested were: No Treatment (To); Trichoderma sp isolate from Langkat rubber (T1) Trichoderma sp isolate from Palm Oil Langkat (T2), Trichoderma sp isolate from Cocoa Langkat (T3), Trichoderma sp isolate from Percut oil palm (T4), Trichoderma sp isolate from Karo Coffee (T5), Trichoderma sp isolates from Karo cocoa (T6) Parameters observed were identification of the fungus Trichoderma sp., pathogenicity test on tobacco plants and percentage of pathogen inhibition. The results of both macroscopic and microscopic identification of Trichoderma sp isolates from rubber plantations in Langkat area (T1) showed that the highest percentage of inhibition and pathogenicity tests against Pussicoccum sp disease of tobacco plants showed negative results (no necrotic spots).

Abstract

Porang tubers (Amorphophallus oncophyllus) have recently garnered more attention with the increasing demand for their derivative products. This research aimed to determine the morphological and chemical characteristics of porang tubers from different harvest periods. The method used was a completely randomized design. Also, for comparison, the morphological and chemical characteristics of bulbils were obtained from previous studies. Based on the analysis, morphologically, the stem tubers have an oval shape developing at the base of the stem with yellowish-brown to orangish-brown skin. Bulbils have an irregular oval shape with brown skin and white spots. They all have similarly dark yellow fibers. The stem tubers in the first harvest period were smaller in diameter and lighter (479.20 ± 183.54 g) than in the second period (609.71 ± 169.42 g). In contrast, bulbils at the leaf axils are smaller (diameter = 3–3.7 cm, thickness = 1.9–2.4 cm) and only weigh about 12.3–25.3 g. Chemical analysis revealed that the flour made from the stem tubers contained 14.28–17.57% glucomannan and 9.16­–11.10% protein, generally higher than bulbils with 25.78% glucomannan and 9.52% protein (very low). The yields of porang flour were 0.15±0.02% and 0.14±0.01% from the first and second harvest.

Abstract

Kopi Arabika merupakan salah satu produk pertanian yang sangat berpotensi dari Kabupaten Dairi. Luas areal Kopi Arabika di Dairi yang terbilang cukup tinggi belum diimbangin dengan produktifitasnya yang hanya sekitar 700 kg/ha setiap tahun nya. Hal ini diakibatkan oleh beberapa faktor salah satunya adalah faktor pemupukan. Pembuatan POC dari limbah yang ada di lahan  petani bertujuan untuk : 1) mengurangi biaya produksi khususnya biaya pupuk, 2) menjaga ekosistem di lingkungan pertanian dengan memanfaatkan bahan organic, 3) meningkatkan produksi tanaman dengan POC sebagai sumber hara tanaman, 4) penggunaan dosis yang tepat, 5) waktu dan pengaplikasian POC yang baik,dan  6) petani mampu membuat pupuk sendiri dari bahan alami. Pembuatan POC diawali dengan pemaparan materi dan diskusi bersama petani Kelompok tani Pahottas Kecamatan Parbuluan IV Kabupaten Dairi dan di lanjutkan dengan praktek masing-masing pembuatan POC yang kemudian dibawa ke rumah masing-masing untuk proses selanjutnya selama 2 minggu.  Hasil dari pembuatan POC ini adalah POC yang siap diaplikasikan ke berbagai tanaman di lahan petani.

Abstract

The rice productivity in Panai Tengah was still relatively low, producing 4.75 Mg ha-1, compared to the national production of 5 to 6 Mg ha-1. Low rice productivity was caused by limiting factors in land use, namely, physical and biological factors, soil chemistry, and agricultural systems. Providing organic fertilizer or municipal waste compost is one way to overcome the constraints on the soil’s physical, biological, and chemical characteristics. This study aims to determine the response to the growth and yield of rainfed rice fields in Kecamatan Panai Tengah with a dose of Municipal Solid Waste Compost (MSWC). This research was conducted by taking soil samples in the rainfed rice fields and then analyzing them in the experimental field at the Faculty of Science and Technology, Labuhanbatu University. The analysis stage was for six months, from seeding to harvesting. The methodology for this study was a non-factorial randomized block design consisting of 7 treatments. The result showed that applying MSWC at a dose of 18 Mg ha-1 showed high yields. The recommendation to farmers was to give 18 Mg ha-1 of MSWC to increase the yields of their rice fields.

Abstract

The transformation of the nest swiftlet house for the cultivation of grey oyster mushrooms is seen as a strategic transition. A few improvements and a little expense given a good value of impact on yield (mushrooms). A total of 119.3 g per bag of grey oyster media produced in the swiftlet house, Sg. Petani, Kedah compared to 149.1 g per media bag in the Environmental Controlled Mushroom House (CEMH), MARDI Headquater, Serdang, Selangor. Although, mushroom yield is higher (CEMH) than swiftlet house but CEMH operating cost is bigger (high electricity consumption). However, there was no significant difference in the yield of mushrooms in the swiftlet house (119.3 g per media bag) with the DANA project mushroom house, MARDI Kedah Office, Alor Setar, Kedah (115.9 g per media bag). Indirectly, giving an entrepreneur a second chance against financial loss.
