Abstract

The hydroponic method could be used as a solution to overcome the difficulty of the availability and continuity of fodder. One of the fodder that can be developed using hydroponic method is sorghum. The purpose of this study was to evaluate the quality of hydroponic sorghum fodder as a feed alternative for ruminants. The treatment used in this study was the use of organic fertilizer as a nitrogen source which was derived from cow and goat manures. The treatments used in this study were P0: 36 ml EM4 + molasses, P1: 36 ml EM4 + molasses + cattle manure, and P2: 36 ml EM4 + molasses + goat manure. Each treatment consisted of 40 g of sorghum seeds. The fodder was harvested at 7, 14 and 21 days of age. The variables observed of this study were nutrient content, in vitro digestibility value, and gas production. Based on the results of the study, it could be concluded that the use of EM4 + molasses + cattle manure as a fertilizer provides the most optimum nutrient content, in vitro digestibility, and gas production of hydroponic sorghum fodder.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh kepemimpinan, motivasi kerja, disiplin kerja, budaya organisasi, kepuasan kerja, dan kompensasi terhadap kinerja kerja serta dampaknya pada produktivitas kerja guru pada SMK Negeri 25, 37 dan 47. Populasi yang digunakan dalam penelitian ini adalah SMK Negeri yang terdapat di wilayah Jakarta Selatan, tetapi dalam penelitian ini penulis mengambil sampel sebanyak 200 responden yang diambil dari SMK Negeri 25, 37, dan 47. Metode penelitian menggunakan Structural Equation Modeling (SEM) dan software AMOS version 6.0. Hasil penelitian menunjukkan terdapat pengaruh yang signifikan antara disiplin kerja, budaya organisasi, kepuasan kerja terhadap kinerja kerja, dan kompensasi kerja terhadap produktivitas kerja. Dalam penelitian ini juga menunjukkan tidak terdapat pengaruh yang signifikan antara kepemimpinan, motivasi kerja, kompensasi terhadap kinerja kerja, dan tidak terdapat pengaruh yang signifikan antara kepemimpinan, kinerja guru terhadap produktivitas kerja.

Abstract

Work on the physical conditioning of the used stator housing and core and the reconstruction of a number of coils can be carried out for the establishment of a single-phase alternator stator winding structure. This work has been carried out in order to achieve two research objectives, namely (i) to recondition the physical condition of the used stator housing and core and (ii) to reconstructa number of coils in the stator core. The research method for fulfilling the reconditioning stages includes cleaning the used stator housing and core, determining grooves, calculating and manufacturing for coil availability adjusted to the number of poles and coil winding type, installing the stator winding structure, and the calculation process in coil manufacture. Fulfillment of the stages ofreconstruction of the coil at the stator core, including the installation of insulation, manufacture of a number of coils according to the determination of the number of poles, installation, connection and bonding of the coils, and calculation of the theoretical value of the output voltage and power.
