ABSTRAK
Sejalan dengan perkembangan zaman dan kemajuan ilmu dan
teknologi, kebutuhan akan ketersediaan energi listrik kian meningkat. Energi
listrik tidak dapat disimpan dalam skala besar, sehingga energi ini harus
disediakan pada saat dibutuhkan. Berdasarkan pertumbuhan jumlah penduduk,
peningkatan pembangunan infrastruktur, pertumbuhan ekonomi dan
ketersediaan energi listrik, maka perlu dilakukan peramalan beban listrik jangka
panjang. Kota Probolinggo mempunyai banyak potensi di antaranya Industri
sebanyak 398 unit juga Pelabuhan Perikanan Pantai (PPP) Mayangan yang
tentunya membutuhkan konsumsi listrik yang sangat besar. Pada penelitian ini
peramalan beban listrik jangka panjang menggunakan metode logika fuzzy
Tsukamoto sebagai solusi peramalan. Kemampuan peramalan sangat baik jika
memiliki nilai MAPE kurang dari 10% dan mempunyai kemampuan peramalan
yang baik jika MAPE kurang dari 20%.
Data yang digunakan adalah data histori yang diambil dari GI
Probolinggo pada tahun 2011 – 2020 yang di dukung dengan jumlah
pertumbuhan penduduk dan nilai PDRB (Produk Domestik Regional Bruto)
yang nantinya akan dibagi dalam beberapa sektor.
Pada Penelitian ini penulis menggunakan fungsi keanggotaan segitiga.

ABSTRACT
In line with the times and advances in science and technology, the
need for electricity availability is increasing. Electrical energy cannot be stored
on a large scale, so this energy must be provided when needed. Based on
population growth, increased infrastructure development, economic growth and
availability of electricity, it is necessary to forecast long-term electricity loads.
The city of Probolinggo has a lot of potential in the Industrial sector as many as
398 units and the Mayangan Pelabuhan Perikanan Pantai (PPP) which requires
very large electricity. In this research forecasting long-term electricity load
using Tsukamoto fuzzy logic method as a forecasting solution. Forecasting
capability is very good if it has a MAPE value of less than 10% and has good
forecasting ability if MAPE is less than 20%.
The data used is historical data taken from GI Probolinggo in 2011
- 2020 which is supported by the amount of population growth and PDRB value
(Produk Domestik Regional Bruto) which will be divided into several sectors.
In this research the author uses the triangle membership function.
This study produces an average MAPE value of 2.4% so that it can be said to be
very good.

Go_Gaming adalah sebuah re-seller yang bergerak dibidang penjualan pc game dan mulai berjalan sejak bulan September 2011. Pada awal memulai bisnis ini go_gaming menggunakan Kaskus dan Twitter sebagai media untuk menjual dan mempromosikan dagangannya, tidak hanya membeli bahkan konsumen dapat memesan game yang tidak ada didalam daftar. Apabila game tersebut ada maka game itu pun akan dijual kepada konsumen yang memesannya dan memasukkan kedalam daftar game. Lambat laun go_gaming merasa membutuhkan sebuah aplikasi yang berbasis web untuk lebih bisa mengontrol data lebih baik lagi dan juga lebih praktis, sehingga bisnisnya dapat berjalan lebih lancar lagi. Untuk itu penulis mempunyai ide membuat sebuah aplikasi penjualan dan pemesanan secara online yang menggunakan bahasa pemrograman php dan sebagai toolnya penulis menggunakan macromedia dreamweaver 8, sedangkan untuk mengedit gambar menggunakan paint, fireworks 8 atau juga bisa dengan adobe photoshop. Lalu untuk melihat hasil penulis menggunakan browser mozila firefox, selain firefox bisa juga menggunakan browser yang lainnya. Untuk menjalankan aplikasi tidak lupa juga harus di instal xampp yang berfungsi sebagai perangkat yang menggabungkan tiga aplikasi ke dalam satu paket, yaitu Apache, MySQL dan PHPMyAdmin. Aplikasi ini terdapat konten-konten menu yang mudah diakses dan dimengerti oleh konsumen dan terdapat kategori-kategori untuk produk, sehingga konsumen dapat mencari game sesuai dengan kategori yang diinginkan. Bukan hanya itu, tapi juga terdapat produk-produk best seller.
