Abstract

ABSTRAK. Penelitian ini bertujuan mengkaji pengaruh dosis herbisida glifosat dan paraquat pada sistem TOT terhadap sifat kimia tanah, karakteristik gulma serta hasil tanaman kedelai. Rancangan yang  digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial yang terdiri dari 2 (dua) faktor yaitu dosis dan herbisida dengan pengulangan sebanyak 3 (tiga) kali. Peubah yang diamati dalam penelitian ini adalah sifat kimia tanah, karakteristik gulma, dan komponen hasil dan hasil tanaman kedelai. Hasil penelitian menunjukkan bahwa semua dosis dan jenis herbisida memberikan peningkatan pH, N-total tanah, dosis 1,50 kg b.a. ha-1 memberikan nilai K-dd yang lebih baik dibandingkan dosis 0,75 dan 2,25 kg ha-1. Dosis 2,25 kg b.a. ha-1 meningkatkan persentase pengendalian gulma dan bobot kering gulma yang lebih rendah, meningkatkan komponen hasil dan hasil tanaman kedelai. Herbisida glifosat dan paraquat memiliki kemampuan yang sama dalam memperbaiki sifat kimia tanah, meningkatkan persentase pengendalian gulma dan menurunkan bobot kering gulma serta meningkatkan komponen hasil dan hasil tanaman kedelai. Interaksi antara dosis 2,25 kg b.a. ha-1 dan herbisida glifosat memberikan nilai persentase pengendalian gulma yang lebih tinggi dan bobot kering gulma yang lebih rendah.The Application of Several Dosage Herbicide Glyphosate and Paraquat in No-Tillage System and Its Influence on Soil Chemical Properties, Weed Characteristics, and Soybean YieldABSTRACT. This study aims to assess the effect of dose of herbicide glyphosate and paraquat on the NT system to soil chemical properties, weeds characteristics of soybean yield. The design used is a randomized completely block design (RBD) factorials consisting of 2 (two) factors herbicide and dose with 3 (three)  replication times. The variables properties of chemical, characteristics of weed, components and yield of soybean. The study results showed that all doses and types of herbicides provided increased pH, total soil-N, 1.50 kg dose ba ha-1 gave the value of K-dd are better than the doses of 0.75 and 2.25 kg ha-1. 2.25 kg dose b.a. ha-1 increased the percentage of weed control and dry weight weed is lower, improving yield and yield components of soybean. Herbicide glyphosate and paraquat have the same ability in improving soil chemical properties, improve weed control and reduce the percentage of dry weight of weeds and increase yield and components and yield of soybean. Interaction between 2.25 kg dose b.a. ha-1 and the herbicide glyphosate give a percentage higher weed control and dry weight weed is lower

Abstract

Ketidaksesuaian/penyimpangan penggunaan lahan di Kecamatan  Montasik dan Blang Bintang terjadi pada lahan sawah irigasi, yang beralih fungsi menjadi bangunan, kebun campuran dan kebun campuran dan bangunan. Terdapat lahan sawah irigasi yang bertentangan dengan ketetapan RTRW. Di Kecamatan di Montasik seluas 167,12 ha (45,37%) dan di Blang Bintang seluas 64 ha (64%). Penelitian ini dilaksanakan di Kecamatan Indrapuri, Ingin Jaya, Montasik dan Blang Bintang Kabupaten Aceh Besar. Analisis data citra dilakukan di Laboratorium GIS Fakultas Pertanian Universitas Syiah Kuala untuk pembuatan peta. Metode yang digunakan dalam penelitian ini yaitu metode analisis spatio temporal yang terdiri dari analisis citra satelit multi temporal, analisis Sistem Informasi Geografis (SIG), dan survey lapangan. Hasil penelitian menunjukkan terjadi penyimpangan lahan sawah irigasi dalam beberapa Kecamatan di Kabupaten Aceh Besar, Terdapat lahan sawah irigasi yang bertentangan dengan ketetapan RTRW. Analysis Of The Deviation Of Extensive Paddy Fields Irrigated In Spatial In Two Districts In Aceh Besar DistrictDiscrepancies/irregularities land uses in Indrapuri, Ingin Jaya, Montasik and Blang Bintang Subdistrict occur in irrigated rice fields, that switch function to building, the garden mix and garden mix and buildings. There are rice fields irrigated contrary with RTRW rules. In Montasik Subdistrict in acre 167.12 ha and Blang Bintang area of 64 ha (64%). This research implemented in Indrapuri Subdistrict, Ingin Jaya, Montasik and Blang Bintang, Aceh Besar Regency. Image data analysis conducted in GIS laboratory of Agriculture Faculty of Syiah Kuala University for the creation of a map. The methods used in this study i.e. spatio temporal analysis method consists of multi temporal satellite image analysis, analysis of geographic information systems (GIS), and survey the field. The results showed irregularities occurred in some irrigated rice fields subdistrict in Aceh Besar Subdistrict, there are rice fields irrigated contrary to RTRW rules.

Abstract

The Characteristics of Soil Physical Properties at the University Farm Station Bener MeriahABSTRACT. The University Farm Bener Meriah located in Tunyang village, Timang Gajah sub-district, Bener Meriah district, has the area of 76.37 ha. The site is allocated as the Bener Meriah Campus of Syiah Kuala University. The University Farm Station has functional as research centre, education and training for farmers, practice field for student, and training for farmers about organically managed of highland commodities. The aim of study are to characterize of soil physical properties and in the area of the University Farm Station Bener Meriah. The descriptive method was use in this research, by means of soil survey and direct observation in the field. The soil survey was carried out by a systematic method (grid system). Based on the research results, field observation, and the analysis of soil physical properties in laboratory, soil physical properties of the area of the University Farm Station were soil texture consisted of sandy loam, loam, and sit loam, soil aggregate stability index ranged from less stable (46.46 – 46.56) to stable (65.40 – 73.90), soil permeability comprised of moderate (2.16 – 4.50 cm h-1), moderately rapid (6.25 – 7.19 cm h-1), and rapid (13.33 cm h-1), soil water content ranged from 31.02 to 37.82%, soil bulk density ranged from 0.82 to 1.16 g cm-3, and soil porosity ranged from 52.56 to 75.34%.

Abstract

Effect of various Types of Bokasi and Dosages on the Change of Macro Nutrient (N, P and K) on Saline Soil and the Grewth of Maize (Zea mays L)ABSTRACT. The research was aimed to find out the effect of various types of bokasi and dosages on the change of macro nutrient (N, P and K) on saline soil and the growth of maize. The research method was a randomized complete block design factorial, consist of two factors. First factor was types of bokasi made from some organic matters decomposited using EM4 I,e. paddy hay, sawdust, and gamal. Second factor wa dosage I.e. 10 ton ha-1, 15 ton ha-1 and 20 ton ha-1. The experiment had three replications so that there were 27 experiment units. Observed variables were chemical soil properties (pH H2O, N total, P available, and K exchangeable at 60 days after incubation), plant growth (plant height at 30 and 60 days after planting, dry weight on top of plant and dry weight on the root at 60 days after planting. The result showed that application of various types of bokasi and dosage gave significant effect on al variable observed. Bokasi from gamal gave the biggest changes of all of observed variable, followed bay paddy hay and sawdust. The higher the bokasi dosage were given, the bigger the changes were occurred on all of observed variable. There were no significant interactions between bokasi types and dosage.
