Abstract

Abstract. Sweet corn production in Indonesia can be increased by intensification program, such as the use of superior cultivars, the use of balanced fertilizer, and the use of organic fertilizer. Objective of the research was to study Integrated Crop Management System, that related to use of fermented organic fertilizer (bokashi) which suitable to sweet corn crop, especially in lowland area of Karawang district. The method of research was experiment. The experimental design was Randomized Block Design, that consisted of 16 treatments and 3 replications. The treatments were 4 bokashi dosage (0, 5, 10 and 15 ton ha-1) combined with 4 varieties of F1 sweet corn (Bonanza, Talenta , Secada and Sweet Boy). The data were analyzed using analysis of variance and Duncan multiple-range test at 5%. The results show that bokashi dosage had given difference on plant height, number of leaves per plant, diameter of the stem, weight of ears, number of grain rows, and yield. Dosages of 10 tons ha-1 bokashi gave the best growth and sweet corn yield of Sweet Boy F1 varieties on Integrated Crop Management System. Keywords: Sweet Corn, Bokashi, CMS. Sari. Produksi jagung manis di Indonesia dapat ditingkatkan dengan program intensifikasi, diantaranya dengan penggunaan kultivar unggul, pupuk berimbang, dan pupuk organik. Tujuan penelitian ini adalah untuk mempelajari sistem pengelolaan tanaman terpadu, yang berhubungan dengan penggunaan pupuk orga-nik bokashi yang cocok pada tanaman jagung manis, khususnya di dataran rendah Karawang. Metode penelitian ini menggunakan percobaan. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok, terdiri dari 16 perlakuan dan 3 ulangan. Perlakuan terdiri dari 4 dosis bokashi (0, 5, 10 dan 15 ton ha-1)  yang dikombinasikan dengan 4 varietas jagung manis F1(Bonanza, Talenta , Secada dan Sweet Boy). Data dianalisis menggunakan analisis varians dan uji jarak berganda Duncan pada taraf 5%. Hasil menunjukkan perlakuan dosis bokashi memberikan perbedaan pada tinggi tanaman, jumlah daun, diameter batang, berat tongkol, jumlah baris biji, dan hasil. Dosis bokashi 10 ton ha-1 memberikan pertumbuhan dan hasil terbaik jagung manis varietas Sweet Boy pada sistem Pengelolaan Tanaman Terpadu. Kata kunci: Jagung Manis, Bokashi, Pengelolaan Tanaman Terpadu

Abstract

This study aims to produce android mobile learning application using appy pie software on temperature and heat materials as a valid physics learning media for senior high school. Research was conducted in Physics Education Laboratory of Riau University. This research is a type of research and development using research design adapted from ADDIE instructional model with Analysis, Design and Develop stage only. Data in this research is validation score from validator with research instrument used is validation quisioner. The data collection technique used is observation by using validation sheet with data analysis technique is descriptive analysis. Each component of android mobile learning applications using appy pie software on temperature and heat material is valid if it has an average score > 2.50 which is in high or very high category. The results of this research indicate that the application of mobile learning "Temperature and Heat" obtained a total validity value of 3.49 and is in very high category. Thus it concluded that mobile learning application "Temperature and Heat" is a valid physics learning media and feasible use in the learning process.
