THE EFFECTIVENESS OF NEEM OIL Azadirachta indica AGAINST Plutella xylostella LEAF CATERPILLAR ON CABBAGE PLANTS
Get PDFABSRTACT Increased production of cabbage plants is often faced with pest problems. Leaf caterpillar Plutella xylostella L. (Lepidoptera: Plutellidae) is a major pest of cabbage plants and if not controlled can decrease both the amount and quality. The use of botanical insecticides is an alternative to controlling P. xylostella insect pests. This study aims to evaluate the effectiveness of neem oil on P. xylostella pests on cabbage plants. The research was conducted in Subdistrict Rasau Jaya, District Kubu Raya, for 4 months. The research design using Randomized Block Design with 8 treatments and 4 replications. The treatment consisted of 5 levels of neem oil concentration, 2 levels of synthetic insecticides and control. Data analysis using ANOVA was continued by Duncan Mutiple Range Test at 5%.

Tanaman padi ialah tanaman pangan yang sering dibudidayakan oleh petani di Kalimantan Barat khususnya di Kabupaten Sambas, tetapi produksi padi yang dibudidayakan masih tergolong rendah yang disebabkan beberapa faktor seperti : pemberian pupuk yang tidak sesuai dengan kebutuhan, pengendalian hama dan penyakit yang tidak maksimal, sistem pertanian padi yang tidak berubah, penggunaan jumlah bibit yang tidak diperhitungkan dalam setiap lubang tanamnya. Penelitian ini bertujuan untuk mengetahui berapa jumlah bibit padi varietas cilosari yang terbaik per lubang tanam di lahan kering Kecamatan Sejangkung Kabupaten Sambas. Penelitian ini dilaksanakan pada tanggal 15 September 2016 sampai dengan 26 Januari 2017 Di Desa Penakalan Kecamatan Sejangkung Kabupaten Sambas, menggunakan Rancangan Acak Kelompok (RAK) terdiri dari 7 perlakuan yaitu b1 (menggunakan 1 bibit per lubang tanam), b2 (5 bibit per lubang tanam), b3 (10 bibit per lubang tanam), b4 (15 bibit per lubang tanam), b5 (20 bibit per lubang tanam), b6 (25 bibit per lubang tanam), b7 (30 bibit per lubang tanam). Masing-masing perlakuan diulang sebanyak 3 kali. Variabel yang diamati dalam penelitian ini meliputi : Tinggi tanaman (Cm), Jumlah Anakan per Rumun (Batang), Jumlah Anakan Produktif (Batang), Jumlah Gabah per Malai (Butir), Hasil Gabah per Petak (Kg), Berat 1000 Butir Gabah (Gram), Persentase Gabah Isi (%), Kerapatan Malai. Berdasarkan hasil penelitian Jumlah bibit padi varietas cilosari di lahan kering Kecamatan Sejangkung Kabupaten Sambas berpengaruh nyata terhadap jumlah anakan per rumpun tanaman, jumlah anakan produktif, kerapatan malai, jumlah gabah per malai, persentase gabah isi sedangkan yang berpengaruh tidak nyata adalah perlakuan tinggi tanaman, hasil gabah per petak dan berat 1000 butir gabah. Hasil pengamatan dilapangan menunjukkan bahwa penggunaan bibit sebanyak 5 batang per lubang tanam merupakan perlakuan yang paling baik di lahan kering Kecamatan Sejangkung Kabupaten Sambas dengan mendapatkan hasil 2,26 kg.

THE EFFECT OF NUMBER OF SEEDS ON PRODUCE AND GROWT OF CILOSARI VARIETIES IN DRY LAND AT SEJANGKUNG DISTRICT OF SAMBAS REGENCY Ihsan1), Radian2) and Maulidi2)Student1) and Lecturer of Agriculture Faculty Tanjungpura University2) ABSTRACTRice (Oryza sativa L) is one of the crops that become the main staple food in indonesia because the most of indonesian’s population brings rice as the source of the main staple food. The rice is a crop that ciltivated freduently by the farmer in West Borneo especially in Sambas regency, but the rice production that had been cultivated still included into poor level in which caused of some factors, that is : unsuitable fertilizing with necessary, pest and disease controling is not maximum, the traditional agricultural system is not chang by the time, the utilization of seed quantity that is not calculated in each planting hole. This reserch’s purpose is to find out how much the best quantity of cilosari varietas seed planting hole in dry land at Sejangkung District, of Sambas Regency. This research conducted on 15th September 2016 to 26th January 2017 in Penakalan Village, Sejangkung District of Sambas Regency by using Randomized Block Design (RAK) consists of 7 treatments, that is : b1(using 1 seed planting hole), b2 (5 seeds planting hole), b3 (10 seeds planting hole), b4 (15 seeds planting hole), b5 (20 seeds planting hole), b6 ( 25 seeds planting hole), b7 (30 seeds planting hole). Each treatments repeated three times. The variabel that observed in this research includes : Planting height (cm), the number of tiller per chill (rice straw), the number of productive tiller (rice straw), the number of grain per panicle (grain), the produce of grain per paddy field (kg), the weight of 1000 grains of grain (gram), grain’s percentage (%), panicle density. Based on the result of this reserch, the quantity of cilosari varietas seed in dry land at Sejangkung District of Sambas Regency had the real effect on the number of tiller per hill. The number of productive tiller, panicle density, the number of grain per panicle, grains persentage. Although, the unreal effect on planting treatment, the produce of grain per paddy field, and the weight of 1000 grains of grain. The result of observation showed that the utilazation of seed as many as 5 rice straw per planting hole is the best treatment in dry land at Sejangkung District of Sambas Regency and got the result 2,26 kg.

The research was conducted on Juni 2016 until Agustus 2016. Soil samples were collected from Pelempai Jaya Village of Ella Hilir Subdistrict, District of Melawi. Soil analysis were conducted in the Biology and Soil Biotechnology Laboratory and Chemical and Soil Fertility Laboratory, Faculty of Agriculture, Tanjungpura University. The parameters observed were soil microorganims activity, soil microorganisms population, soil pH, C-organic, total N, C/N ratio, soil bulk density, soil texture and soil water content. The results showed that the types of land use caused a significant different in both activity and the number of soil microorganisms. Actvity and soil microorganisms population highest in rubber plantation (28,12 CO2/100 g/day and 5,062 x 106 CFU g-1). Activity and soil microorganisms population lowest in upland rice field (776 CO2/100 g/day 6 x 105 CFU g-1).
