Abstract

Saat ini biji kakao (TheobromacacaoL) merupakan salah satu hasil pertanian yang memiliki harga jual yang cukup tinggi. Salah satu tahapan dalam pengolahan biji kakao adalah proses pemilihan kualitas kadar air biji kakao. Disini para petani mengalami kesulitan dalam mengecek kadar air karena sangat berpengaruh dalam penetuan harga jualnya. Berdasarkan hal tersebut peneliti membuat sebuah alat uji kadar air biji kakao dengan implementasi menggunakan sensor Soil Moisture, diprogram dan dibuat menggunakan Arduino IDE pada mikrokontroler arduino uno r3 yang sangat mudah penggunaanya dengan menancapkan ketumpukan biji kakao yang sudah dikumpulkan dalam wadah sehingga mempermudah petani dalam mengambil keputusan untuk menjual atau menjemurnya kembali supaya petani tidak rugi. Hasil pembacaan data dari sensor soil mosture peneliti menggunakan LCD monitor sebagai penampil hasil uji, LED warna hijau untuk kadar air bagus, LED warna kuning untuk kadar air sedang, dan LED warna merah untuk kadar air tinggi. Hasil penelitian memperlihatkan pengujian yang menggunakan wadah yang didalamnya sudah terdapat biji kakao dalam jumlah 1 kg dengan kondisi kadar air bagus hasil dari alat yang dijual yaitu 6% dan pada alat penelitian 6.5% jadi dapat diambil kesimpulan alat yang dibuat dapat digunakan untuk mengukur kadar air biji kakao dengan tingkat error yang kecil sebesar 0.5%.

Abstract

CV Dwi Putra is one of the chip shops that sells various types of chips with various flavors. However, in managing inventory, they still use manual methods that lead to inaccuracies in stock quantities between reality and records, as well as the lack of computerized systems to manage incoming and outgoing goods. Manual data processing also causes errors in recording final stock, delays in making reports, and makes CV Dwi Putra staff have to calculate and re-record the amount of stock of goods. In addition, the difficulty of determining the updated cost of goods sold is also a problem. The system is built using the Extreme Programming development method, as well as using use case diagram design models, activity diagrams, and class diagrams to illustrate inventory information system models. In its creation, this system uses PHP, HTML, JavaScript, JQuery, and MySQL programming languages, using the Codeigniter Framework. The inventory information system that has been developed has benefits in managing stock data better than the previous system. The system is able to manage incoming goods data (purchases) and outgoing goods data (sales), so as to reduce errors in recording final stock. In addition, the system also helps in making purchase and sales reports easier, faster, and on time. By using the Moving Average Cost method, the system also helps in determining the cost of goods sold when there is an increase or decrease in price.
