Therefore, countermeasures from polluting cow dung into organic fertilizer and domesticated sewage into growing media platform for applying organic fertilizer to prevent and reduce pollutants in the environment, and also promote the use of organic fertilizer as alternative is scarce and expensive fertilizer in agriculture. The study employed qualitative methods with a PAR approach using data retrieval techniques that jump diretly into the study. While the main targets of this study are the Lendang Bunga youth. At least the solution offered on the problem might reduce pollution of the environment and contribute to communities especially farmers. During this activity yong blossom lenders enthusiastically follow the program step. Young pople can meke their own organic fertilizer and create the growing and apply media by growing in and putting it in the yard.

Some of the weakness of using transformer is cost by some losses in core. By solving this problem, it can save more energy usage. To calculate the losses in traditional techniques, it can use nonlinear programming, numerical method and others. Other than that, Finite Element Method (FEM) can be used. It can predict the period for transformer; calculate core losses, flux distribution and others. In this project, FEM technique is applied to calculate the flux and loss distributions in single phase transformer using MATLAB software. This also presented the localized flux density and loss over a core. As the result, the software must be agreed with the experimental data. vii ABSTRAK Pemboleh ubah voltan adalah salah satu alat yang penting yang selalu digunakan di dalam kilang. Salah satu kelemahan ketika menggunakan pembolehubah voltan ini adalah masalah kewangan disebabkan ada sedikit pembaziran di dalam teras pemboleh ubah. Dengan menyelasaikan masalah ini, ia dapat menjimatkan lebih banyak tenaga yang digunakan. Untuk mengira pembaziran menggunakan cara lama boleh digunakan teknik "nonlinear programming", "numerical method" dan lain-lain teknik lagi. Selain dari itu, "Finite Element Method (FEM)" juga boleh digunakan. FEM boleh menjangka tempoh hayat sesuatu pembolehubah, mengira pembaziran di teras, penyebaran medan magnet dan lain-lain. Di dalam projek ini, teknik FEM digunakan untuk mengira medan magnet dan pembaziran di dalam pemboleh ubah satu fasa dengan menggunakan sistem MATLAB. Ia juga boleh mengesan kepadatan medan magnet dan pembaziran keatas teras. Sebagai kesimpulan, sistem MATLAB yang digunakan mestilah mengikuti dengan data semasa membuat eksperimen. viii
