Purpose: The purpose of this study is to reduce the level of work accidents in stadium construction by developing risk-based work breakdown structures. Methodology: The research methodology includes several stages, namely the literature study, analysis of data archives and previously related project and research, as well as through the validation of experts. Result: The results of this study are WBS standards, implementation methods, activities, resources, potential hazard risks and safety planning using risk-based WBS standards on stadium construction work, as a method in preventing, reducing, eliminating or even nulliying the chance of accident throughout the development of a construction work. Applications/Originality/Value: This research will hopefully provide benefits to the construction world by presenting work accidents prevention methods by incorporating risk elements into each level of project work in the Work Breakdown Structure which will be used as input in the making of a safety plan.

Tujuan penulisan jurnal ini adalah untuk membuat aplikasi pemesanan alat kontrasepsi keluarga berencana untuk membantu pegawai Badan Keluarga Berencana dan Pemberdayaan Perempuan (BKB-PP) kota Palembang khususnya Sub Bagian Umum dan Gudang dalam melakukan pencatatan data pemesanan dan pengiriman alat kontrasepsi. Setelah penulis melakukan observasi dan wawancara maka diketahui bahwa masalah yang ada pada Sub Bagian Umum dan Gudang BKB-PP kota Palembang adalah belum adanya aplikasi khusus yang dapat membantu dalam mengelolah data pemesanan dan pengirim alat kontrasepsi, sehingga dalam pencatatan data pemesanan masih dilakukan secara konvensional dengan menggunakan kertas, dengan demikian maka penulis memutuskan untuk membuat aplikasi yang lebih aplikatif dan mudah digunakan untuk membantu dalam efesiensi kerja pegawai BKB-PP kota Palembang. Aplikasi pemesanan alat kontrasepsi keluarga berencana yang dibuat menggunakan program Visual Basic.Net 2008 dengan database MySQL yang mengkasilkan 16 form dan lima report.

Background: Clean water supply can be obtained from various sources, both groundwater and surface water. Groundwater often contains high levels of iron (Fe). Many residents are forced to use water which in terms of quality does not meet the requirements, one of which is the chemical elements in the form of high iron content which can cause diarrhea, anemia, kidney damage that ends in death. Methods: This research is an experimental study to determine the effectiveness of bagasse activated carbon thickness in reducing iron (fe) levels in groundwater in Kebon Jeruk district, west Jakarta. This research was conducted at the workshop of environmental health department of health polytechnic of the ministry of health Jakarta. The water sample used was 45 liters, samples from electric pump wells treated with sugarcane bagasse activated carbon filtration with a thickness variation of 0 cm as control or without activated carbon bagasse, 30 cm, 45 cm, 60 cm, and 75 cm. Result: results of chemistry laboratory research at the department of environmental health polytechnic of the ministry of health Jakarta on the content of iron (fe) in groundwater, iron content (fe) before processing by filtration method using bagasse pulp activated carbon as much as 2.99 mg / l against allowable iron (fe) levels for clean water quality requirements based on ministry of health regulation no. 32 in 2017, the maximum allowable content of 1.0 mg / l. Conclusion: of the five treatments the most effective thickness of activated carbon reduces iron (fe), is at a thickness of 45 cm because it has been able to reduce iron levels below the maximum allowable level based on ministry of health regulation no. 32 in 2017 which is 1.0 mg / l.

This study aims to develop big book media for learning Indonesian in grade 3 elementary school and to determine the feasibility of big book learning media. This research uses research and development (R&D) methods using the FOUR-D (Define, Design, Develop and Disseminte) model. The data collection technique used is by using questionnaires and trials. The feasibility of big book learning media is obtained from the results of media validation and testing. Validation was carried out by material experts and learning media experts. The results of the research show that the validation of the material experts and the validation of the learning media experts are very valid. The trials used in this study were limited to 10 students and received a very good response. The results of this development research indicate that the big book media for learning Indonesian in grade 3 Elementary School is very suitable for use in learning in Elementary School.Â

Dalam penelitian ini bertujuan untuk mengetahui keefektifan metode drill (latihan) dalam pengajaran perbaikan pada anak diskalkulia. Penelitian ini menggunakan library research untuk pengumpulan datanya. Gangguan berhitung atau diskalkulia dalam penelitian sebelumnya menunjukkan bahwa dari kelas bawah hingga kelas atas masih ditemukannya siswa yang mengalami gangguan berhitung. Dengan begitu perlu adanya solusi dalam peningkatan belajar untuk meningkatkan kemampuan siswa dalam kemampuan berhitung. Dari hasil study literatur menunjukkan hasil metode drill dalam proses pembelajaran perubahan pada nilai siswa, selain itu metode drill juga berhasil meningkatkan keaktifan siswa di kelas. Pengajaran perbaikan dalam usaha membantu siswa yang mengalami gangguan berhitung untuk meningkatkan kemampuan mereka. Sehingga dalam implementasi pengajaran perbaikan dengan metode drill akan meningkatkan kemampuan siswa dalam berhitung dan akan mengurangi anak kesulitan berhitung (diskalkulia).
