KSP (Koperasi Simpan Pinjam) Makmur Mandiri bergerak dalam usaha perkreditan yang menyediakan pinjaman atau kredit sebagai mana koperasi pada umumnya. Sistem penerimaan pinjaman dalam KSP Makmur Mandiri yang sedang berjalan dilakukan dengan cara calon peminjam datang ke lokasi koperasi dengan mengajukan peminjaman kemudian karyawan mendata peminjam ke dalam form rekomendasi anggota setelah itu form rekomendasi anggota tersebut diberikan kepada pimpinan koperasi.
Masalah yang terjadi pada KSP Makmur Mandiri adalah kehadiran pimpinan koperasi yang sering tidak ada di koperasi, sehingga pengajuan pinjaman yang ada di koperasi menumpuk dan tidak dapat segera di tentukan hasil kelayakan pinjaman. Selain itu masalah yang juga terjadi di koperasi adalah penilaian yang dilakukan pimpinan dalam menentukan kelayakan pinjaman masih bersifat subyektif yaitu hanya memberikan keputusan layak atau tidak seorang peminjam, tanpa memperhitungkan persentase nilai kelayakan pinjaman  tersebut.
Solusi untuk menyelesaikan masalah ini maka dibuatlah sebuah keputusan penentuan kelayakan yang mampu membantu pimpinan dalam proses penilaian dan memberikan perhitungan tepat dalam menilai kelayakan pinjaman. Metode yang dapat mendukung keputusan adalah Fuzzy logic, karena penilain yang bersifat subyektif atau non-linear dapat dimodelkan dan dihitung secara tepat.

A musical instrument is a device created to produce sound. The price of musical instruments themselves varies depending on the type of instrument and the quality of the material used to make the instrument. At NU 07 Brangsong Middle School, there were no instruments except tambourines. That is because there is no funds to buy a musical instrument. The school allocates more funds to buildings or school buildings and scholarship assistance for underprivileged children and intelligent children. Thus students at the school cannot practice or hone their skills in music. From these problems can actually be solved by an arduino-based Piano, Harp, Marching Bell Digital instrument using laser light and LDR. Because this tool can be made at a low cost and can function more than one musical instrument. The working system of this tool is that there are several lasers that will emit light directly on the LDR sensor (in pairs). And when a pair of laser beams and LDR number one are blocked by an object or hand it will emit a piano sound with a "DO" motif. Furthermore, when a pair of laser beams and LDR number two are blocked, it will emit piano sound with the "RE" orientation and so on. This tool is also equipped with buttons that function as a selector of the type of sound that will be generated and the desired octave.
