Abstract

Serangan penyakit karat tumor pada sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) yang disebab- kan oleh fungi Uromycladium tepperianum (Sacc.) Mc. Alpin. masih terjadi di hampir semua wilayah pertanaman sengon di Jawa. Upaya pengembangan teknik pengendalian penyakit ini, seperti pengembangan fungisida alternatif masih perlu dilakukan. Tujuan penelitian ialah untuk mengetahui efektivitas jenis dan dosis fungisida hasil formulasi berbasis tembaga dan boron serta pemangkasan yang dilakukan dalam menekan pertumbuhan penyakit karat tumor pada tanaman sengon. Percobaan dilakukan menggunakan rancangan faktorial dalam rancangan acak lengkap dengan tiga faktor, yaitu pemangkasan, jenis fungisida dan dosis yang digunakan. Fungisida sebanyak 10 ml diaplikasikan pada tanaman sengon dengan metode injeksi batang setiap bulan. Hasil penelitian menunjukkan kedua fungisida yang diuji menunjukkan efektivitas yang berbeda. Perlakuan fungisida CC dosis 10% pada tanaman sengon yang dipangkas dan tidak dipangkas dalam waktu dua bulan mampu menekan karat tumor sebesar 4,2 buah. Pada perlakuan fungisida PG dosis 10% pada tanaman yang dipangkas mampu menekan karat tumor sebesar 4,8 buah, tetapi pada sengon yang tidak dipangkas mampu menekan karat tumor sebesar 1,6 buah. Fungisida CC lebih efektif menekan karat tumor pada sengon yang tidak dipangkas sedangkan pada sengon yang dipangkas lebih efektif menggunakan fundisida PG.

Abstract

Nyamplung and Malapari a potential bioenergy crops on marginal land to be developed on the coastal land. The constraints of the coastal land is the less of water and soil nutrient. Input technology is needed in order to suceed the crop planting such as using bio fertilizer. Mycorrhizae plays an essential role in helping plants to absorb phosphate and increase the resistance to drought. Trichoderma spp involves in producing beneficial hormones for metabolism and helps break down organic matter. Utilization of biofertilizer is still rarely used as treatment in bioenergy plant seedlings. This study aimed to determine the quality of nyamplung and malapari seedlings after mycorrhizal and Trichoderma spp application in the nursery. Experiments were arranged in a complete randomized block design (RCBD). The treatment of media: soil as control (T), soil+organic fertilizer with ratio of 3:1(TK), soil+organic fertilizer+mycorhizae 10 g (TKM), soil+organic fertilizer+Trichoderma spp 10 g (TKT), soil+organic fertilizer+mycorrhizal 10 g+Trichoderma 10 g (TC). Application was done when the seedlings reached 1 (one) month old. Biofertilizer was sown around seedling roots. Each treatment consisted of 50 samples and 3 replications so the total seedlings were 750 seedlings. The results showed that after 6 and 12 months treatment malapari with organic fertilizer + mikoriza + Tricoderma spp (TC) gained 67.5% taller and 427% larger on dry weight of leaf than the control, whereas in nyamplung seedlings, TC treatment resulted better growth with diameter 8% larger, root length 78.56% longer, and total dry weight 7.88% heavier compared to control (T).

Abstract

Maruca testulalis is one of pest on leaves of Pongamia pinnata (L.) Pierre. leaf in nursery. The objective of this research was to compare the efficacy of insecticides on larvae population and degrees of damage intensity. The research used complete randomized design with five treatments and three replications. The treatments were control, azadirachtin 5 g/l, Bacillus thuringiensis 1 g/l, klorantraniliprol 1 g/l and monosultap 0.5 ml/l. The results showed that tested insecticides influence on the intensity of M. testulalis. Klorantraniliprol azadirachtin and monosultap insecticides were more effective to control the larvae of M. testulalis when compared to B. thuringiensis.

Abstract

Nyamplung (Calophyluminophylum) merupakan salah satu jenis tanaman yang dikembangkan sebagai tanaman penghasil biofuel. Penanaman nyamplung banyak mengalami gangguan berupa serangan hama trips (Heliothrips haemorrhoidalis Bouche) dan hama penggerek pucuk. Upaya pengendalian hama terpadu ditekankan pada pengurangan penggunaan insektisida sintesis dengan penggunaan insektisida nabati. penelitian ini bertujuan untuk mengetahui efektfitas beberapa jenis insektisida terhadap hama trips dan penggerek pucuk. Penelitian menggunakan rancangan acak lengkap (RAL) yang terdiri dari 3 perlakuan (kontrol, insektisida kimia dan ekstrak daun sirsak). Setiap perlakuan di ulang sebanyak 30 kali, sehingga total tanaman sebanyak 90 tanaman. Hasil penelitian menunjukkan bahwa Ekstrak sirsak efektif menurunkan tingkat kerusakan hama penggerek pucuk sampai 10% sedangkan insektisida kimia efektif menurunkan tingkat kerusakan hama trips sampai 85%.

Abstract

The purpose of this study was to determine the weed density and the dominant species of weeds in Malapari (Pongamia pinnata (L). Pierre) agroforestry. The study was conducted in Patutrejo Village, Grabag District, Purworejo Regency. The method used is single plot method in malapari agroforestry, as a comparison of observations of weeds on empty land that is not planted. Weed sample collection was carried out by the quadratic method measuring 1 m x 1 m as many as 3 plots placed in malapari agroforestry and empty land diagonally. Observations were repeated 3 times so that there were 18 observation plots. The results showed that weed density in malapari agroforestry (29.95) was lower than empty land (54.17). The dominant species of weeds in both malapari agroforestry and empty land is Eulalia amaura (Buese) with Important Value Index (IVI) of 36.40 % and 43.39 %. This species is a pioneer weed and fast growing, so monitoring and control are needed so that the weed population is not economically disserve.Keywords: agroforestry, density, dominant, malapari, weed
