Abstract

Palm oil fronds is one of the wastes originating from the oil palm industry which are difficult to decompose. The right decomposer application is one of the success keys, if the oil palm fronds are processed into compost hence the expected quality of compost is achieved. This research aim was to determine the quality of oil palm fronds compost with Trichoderma harzianum and cow dung application based on N, P, K nutrients content, C-organic and C/N compost ratio. The research design used was factorial complete randomized design, the first factor was cow dung (0 kg, 1 kg, and 2 kg) and the second factor was Trichoderma harzianum (0 g, 50 g, and 100 g). Research observations included compost temperature, compost pH, N, P, K, C-organic, and C/N compost ratios. The results showed that the application of cow dung, Trichoderma harzianum and their interactions had no significant effect on N, P, K nutrient content, C-organic, and C/N compost ratios, as a whole, the observed compost characteristics met compost criteria based on SNI 7030-200.

Abstract

This study aims to get the response of plant vegetative growth banana (Musa paradisiaca sapientum L) effect to the use of goat manure and fungus Trichoderma harzianum and the combination of both treatments. The research was conducted in the area of the garden village Selamat District of Biru-Biru with altitude 200 m above sea level. The study was conducted from April 2014 through August 2014. This study used a randomized block design factorial consisting of two factors, namely goat manure dose factor (K) consists of 3 levels of treatment: K0 = 0 kg/plant, K1 = 2.5 kg/plant, K2 = 5 kg/plant and dosing frequency factor fungus Trichoderma harzianum (T) consists of 3 levels of treatment are: T0 = 0 g/plant, T1 = 25 g/plant and T2 = 50 g/plant. Parameters were observed in this study is plant height (cm), number of leaves (pieces), stem diameter (cm). The results showed goat manure significantly affected plant height and diameter growth of banana stem. Goat manure is best obtained at a dose of 5 kg/plant. Fungus Trichoderma harzianum significant effect on plant height at a dose of 50 g/plant, but no real effect on the number of leaves and stem diameter. Interaction dose goat manure and fungus Trichoderma harzianum giving no real effect on the vegetative growth of banana.

Abstract

Ganoderma boninense is afungus that causes the disease rotting the roots (basal stem rot). Infection and disease transmission generally occurs through the contact ofthe root or the base ofthe stem with a source inokulum in the ground. Ganoderma boninense can cause death in plant oil palm. Trichoderma sp saprofik is a fungus that lives in the soil, litter, dead wood, and living in various places. Easy to find, quickly, and which were capable o f killing other fungi.

Abstract

Elaeidobius kamerunicus is one of the weevil pollinator of oil palm. Weevil pollinator, E. kamerunicus in plantation is useful to increase fruit set. Continuity of the oil palm pollination require minimal amount of the weevil. This research to know aggressiveness and population dynamic of the weevil E. kamerunicus in flower of oil palm at Grea Estate PT. Karya Hevea Indonesia. This research uses descriptive analysis method consists of observing and collecting data about the aggressiveness and population dynamics of weevil pollinators visit in anthesis male flowers and receptive female flowers of oil palm of seven years after planting. Observations were made on an hourly basis, starting at 08:00 am until 15:00 pm. Observations were made daily on trees with receptive flowers and anthesis flowers, carried out for 20 days with a different tree every day. The results showed that the aggressiveness of the weevil Elaeidobius kamerunicus as the main oil palm pollinating insect had a significant difference in interest. Where E. kamerunicus tend to be more aggressive to visit the male flower anthesis as many as 1399 tails of the visiting receptive female flower that only 25 tails. Effect of temperature on the population dynamics of E. kamerunicus visit also differ between male flowers and female flowers. For male flowers, E. kamerunicus is more active at 27 ° C. While in the female flowers, E. kamerunicus is active at 30 ° C. E. kamerunicus actively visited male anthesis flowers and receptive female flowers at 63% and 62% moisture respectively.

Abstract

Weeds are undesirable plants because they can compete with the oil palm. Weed growth can reduce the production of bunches by 20%. Weeds are not only due to competition against nutrients but also produce allelopathic substances that are toxic to oil palm. Inventory and find out the dominance of weed species is needed in the management of effective weed control. The study aims to determine the diversity of weeds in different areas of planting year. This study used a sampling method carried out on two mature areas (18 years and 8 years) and an immature area (1 year), with the direct observation method. Every planting area is made of 2 large plots with a size of 20 m x 60 m at interrow of palm, then inside there are made 6 small plots with a size of 2 x 2 m. Data were analyzed with SDR (Summed Dominance Ratio) value to determine the dominant weed species. The diversity of weeds from each area is varied, there are 29 species of weeds and 20 families, nevertheless, there are 5 species of weeds found in all areas of study; O. nodusa, Poaceae; C. kyllingia, Cyperaceae; A. comressus, Poaceae; P. Niruri, Phyllanthaceae; A. spinous, Amaranthaceae. The dominant weeds in the immature area are E. indica, Poaceae while in the mature areas are O. nodosa, Poaceae.

Abstract

Penelitian ini bertujuan untuk mendapatkan aplikasi pupuk an organik dan campuran biochar dengan pupuk kandang yang tepat untuk pertumbuhan kacang kedelai. Penelitian dilakukan dengan menggunakan Rancangan Split Plot Design dimana petak utama pemberian pupuk anorganik (F) terdiri dari 2 taraf, yaitu : F0 (tanpa diberi pupuk anorganik); F1 (diberi pupuk anorganik), anak petak yaitu campuran biochar dengan pupuk kandang (K) yang terdiri dari 6 taraf yaitu: K1 (Biochar sekam padi + pupuk kandang ayam); K2 (Biochar sekam padi + pupuk kandang sapi); K3 (Biochar serbuk gergaji + pupuk kandang ayam); K4 (Biochar serbuk gergaji + pupuk kandang sapi); K5 (Biochar tangkos kelapa sawit + pupuk kandang ayam); K6 (Biochar tangkos kelapa sawit + pupuk kandang sapi). Aplikasi pupuk anorganik dan campuran biochar dengan pupuk kandang memberikan perbedaan nyata pada tinggi tanaman, jumlah klorofil, dan total luas daun, sedangkan interaksi keduanya hanya berpengaruh nyata pada tinggi tanaman dan total luas daun. Perlakuan terbaik diperoleh pada perlakuan aplikasi pupuk anorganik, kombinasi pemberian pupuk anorganik dengan biochar tankos sawit + pupuk kandang ayam. Sedangkan aplikasi biochar sekam padi + pupuk kandang sapi, biochar tankos sawit + pupuk kandang ayam, biochar serbuk gergaji + pupuk kandang ayam menunjukkan nilai terbaik.

Abstract

Penelitian ini bertujuan untuk mendapatkan dosis pupuk kandang dan bakteri pelarut fosfat Rhiphosant yang tepat untuk pertumbuhan dan produksi kacang hijau di lahan kering. Penelitian dilakukan di Desa Tanjung Rejo, Kecamatan Percut Sei Tuan. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) Faktorial dengan dua faktor dan tiga ulangan. Faktor pertama adalah pupuk kandang (P) terdiri dari P0 (0 ton/ha), P1(3 ton/ha), P2 (6 ton/ha dan P3 (9 ton/ha). Faktor kedua aplikasi BPF Rhiphosant (B) terdiri dari perlakuan B0 (0 kg/ha), B1(1 kg/ha), dan B2 (2 kg/ha). Aplikasi pupuk kandang memberikan perbedaan tidak nyata pada bobot kering tanaman dan indeks panen tanaman kacang hijau di lahan kering. Namun pupuk kandang memberikan efek berbeda nyata pada komponen hasil panen yaitu jumlah polong dan bobot biji. Perlakuan BPF Rhiphosant memberikan efek tidak nyata pada pertumbuhan vegetatif dan komponen panen. Demikian juga kombinasi perlakuan pupuk kandang dan BPF Rhipohosant menunjukkan pengaruh tidak nyata untuk semua parameter yang diamati, sehingga belum diperoleh kombinasi dosis yang tepat untuk mendukung pertumbuhan dan produksi tertinggi kacang hijau di lahan kering.
