Abstract

Non-conventional feeds are generally of low quality so feed fermentation needs to be done to increase its use. This research was conducted to examine the effect of giving fermented feed types on egg quality. This research was conducted in June until August 2018 in the cage of Cibadak poultry in Sukabumi district. The animals used in this study were 24 Brown Strain Isa Brown laying hens as many as 24 birds. The study used a completely randomized design (CRD) consisting of 6 treatments and 4 replications. The treatment in this study was R0 = 100% Basic Ration, R1 = 90% Basic ration + 10% fermented non conventional ration, R2 = 80% Basic ration + 20% fermented non conventional ration, R3 = 70% Basic ration + 30% Non ration conventional fermented, R4 = 60% Basic ration + 40% Fermented non-conventional ration, R5 = 50% Basic ration + 50% Fermented non-conventional ration. The data obtained were analyzed using Analysis of variance (ANOVA), if the data showed results that were significantly different (P <0.05) followed by the Duncan test. The results showed that substitution feeding did not significantly influence the egg index, egg white weight, Haugh Unit value, and shell thickness. Therefore, it can be concluded that demonstrable non-conventional feed can be given in ration of laying hens up to 50%.

Abstract

Tungro adalah salah satu penyakit penting pada padi, yang disebabkan oleh dua jenis virus, yaitu Rice Tungro Bacilliform Virus (RTBV) dan Rice Tungro Spherical Virus (RTSV), melalui vektor wereng hijau (Nephotetic virescens). Tingginya intensitas pertanaman menyebabkan keseimbangan unsur hara semakin berkurang, termasuk unsur silika (Si). Pemberian pupuk silika dengan dosis yang tepat dapat meningkatkan kesuburan tanah dan menyebabkan tanaman lebih tahan terhadap serangan hama penyakit. Tujuan penelitian ini untuk mengkaji pengaruh pemberian pupuk silika dalam pengendalian penyakit tungro. Penelitian menggunakan rancangan faktorial dua faktor. faktor pertama yaitu dosis pemberian pupuk silika (kontrol, NPK dosis umum digunakan petani, 1/3 NPK + 1 lt si, 1/3 NPK + 3 lt si, 1/3 NPK + 5 lt si), faktor kedua adalah penggunaaan varietas (inpari 36 dan TN1). Hasil penelitian menunjukkan bahwa interaksi pemberian dosis pupuk silika dan varietas tidak berpengaruh nyata terhadap semua parameter pengamatan, kecuali pada hasil gabah. Varietas berpengaruh nyata terhadap tinggi tanaman, panjang malai, dan hasil gabah.

Abstract

Usually, commodities shift occurs from food crops to commercial crops, such as horticulture with the aim of improving the welfare of farmer’s life. However, a different situation happened in Sedong Subdistrict, Cirebon Regency where mango farmers switched to paddy cultivation which is a non commercial crop. Most mango farmers began to abandon mango cultivation and made paddy cultivation as their main livelihood. Therefore this research aimed at analyzing the factors underlying the farmer’s decisions to abandon or continue mango cultivation and describing the potential and constraints of mango cultivation. Samples taken were 65 farmers in Sedong Subdistrict, Cirebon Regency consisting of 30 present-grower of mango who also experienced paddy cultivation and 35 past-grower of mango who switched to paddy cultivation. The research method used is the survey research method with data analysis using descriptive statistics and crosstabulation analysis with the fisher exact test. The results showed that the factors related to the farmer's decision to abandon or continue mango cultivation consisted of age, farmer's perception of mango cultivation, risk taking attitude, land tenure status, land area, and farmer group membership. Mango farming has easy transportation in the marketing activities provided by traders, as well as ease of access to credit bunt only for large scale farmers. The constraints felt by farmers in conducting mango farming consist of limited capital for small farmers,

Abstract

Residents of agrarian areas are residents who depend their livelihood to agricultural products, but the production of community plantations is often not as desired. Our research aims to know  influence the physiological response of weeds to glyphosate herbicide and paraquat herbicide. This experiment was conducted at the UGL Kutacane Faculty of Agriculture experimental garden, Babussalam Subdistrict, Southeast Aceh Regency, which ran from January to February 2018. This study used a non-factorial Randomized Block Design (RBD) consisting of 4 treatment levels: H1: Glyphosate Herbicide = 300 ml/4 L water; H2: Glyphosate herbicide = 1000 ml/13 L water; H3: Herbicide Paraquat = 300 ml/4 L water; H4: Herbicide Paraquat = 1000 ml/13 L of water. The results of Glyphosate Herbicide 1000 ml / 13 L of water effectively control total weeds up to 14 HSA. Glyphosate herbicide is able to inhibit the 5-enolpiruvil-shikimat-3-phosphate synthase (EPSPS) enzyme which plays a role in the formation of aromatic amino acids. The author concludes that the recommended dose of glyphosate based on the research is 1000 ml/13 L of water, because the dose is herbicide Glyphosate has been able to suppress total weed growth.
