Abstract

Ulat daun bawang merah (Spodoptera exigua Hubn.) merupakan hama utama pada pertanaman bawang merah, yang dapat menurunkan hasil produksi, sehingga mengakibatkan kerugian yang cukup besar bagi petani. Rimpang jeringau (Acorus calamus L.) dapat berperan sebagai racun perut, racun kontak, anti-feedant dan repellent bagi serangga. Penelitian ini bertujuan untuk mengetahui pengaruh beberapa konsentrasi Ekstrak Rimpang Jeringau (ERJ) terhadap mortalitas larva S. exigua. Penelitian dilaksanakandi Laboratorium Ilmu Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Tadulako Palu pada bulan Juni sampai September 2016. Pengujian aktivitas insektisida ERJ dilakukan dengan menggunakan metode pencelupan dan disusun dalam Rancangan Acak Lengkap (RAL) dengan 6 tingkat konsentrasi ERJ, yaitu K0: Kontrol (Tanpa Perlakuan) K1: ERJ (1,5%), K2 : ERJ (2%), K3 : ERJ (2,5%), K4 : ERJ (3%) dan K5 : ERJ (3,5%).Hasil penelitian menunjukkan bahwa ERJ 3% menunjukkan aktivitas insektisida yang tertinggi. ERJ 3% menyebabkan kematian larva S. exiguainstar 3 sebesar 65,42% dan menghambat pembentukan pupa dan imago S. exigua sebesar 99,1%  Kata kunci: Acorus calamus L., Aktivitas insektisida, Ulat daun bawang merah

Abstract

The research implemented in Mpanau Village, Sigi Biromaru, Sigi Regency. The study began from March to May 2016. The purpose of this research is to know the effect dosage of bran and corn flour on sawdust media to growth and yield of white oyster mushroom (Pleurotus ostreatus). The benefits of this research isa source of basic scientific provides information the growth and yield of white oyster mushrooms to the dosage of bran and corn flour as source of nutritious white oyster mushroom plant, In addition it is expected to be a reference for future researchers about mushrooms white oyster. The method of this study was arranged in the design of this the study using Completely Randomized Design (RAL) with 7 treatments as follows: D0 =  media sawdust (100%), as control, D1 = sawdust (80%), and bran (20%), D2 = mixture of sawdust media (75%), and bran (25%), D3 = mixed sawdust (70%), and bran (30%), D4 = mixture of sawdust (80%), and corn powder (20%), D5 = mixture of sawdust media (75%) and corn powder (25%), D6 = mixed sawdust (70%), and corn power (30%). The results of this study showed that the addition of dosage of bran and corn powder to each treatment of sawdust media had a very significant effect on all parameters of observation that is on the first observation parameter growing mycelium, the number of white oyster mushroom body, white fruits oyster mushroom cap dry weight of white oyster mushrooms. Treatment with 30% dosage of bran dose gave the best result to all observation parameters except on observation parameter of white oyster mushroom diameter. On the average parameter of white oyster mushroom fruits diameter the best treatment was treatment (D1) with dosage 20% of bran. Treatment by using a dosage of corn powder gives a low yield on all observation parameter. Keywords: Oyster mushrooms, Sawdust

Abstract

The purpose of this study is to predict the rate of erosion based on some slope in the village of Molino Petasia Eastern District of North Morowali district. The usefulness of this research can used as a source of information for the government in general and provide information about the amount of erosion potential. The research was conducted in December 2015 and February 2016. This study used directly in the field survey and soil sampling for analysis of materials in laboratorium. Then the results of the analysis processed by using the formula USLE (Universal Soil Loss Equation). The results showed that the rate of erosion that occurred in PT. Agro Nusa Abadi is high, moderate to low. Erosion is highest at an inclination of 3% and 8%, while the erosion rate was at an inclination of  3% on replicates 2 and 3, the slope of 8% on repeat 1 (first) whereas the low level of erosion found on a slope of 1%. Keywords: Erosion Prediction, Palm oil and Slope
