Abstract

Penelitian ini bertujuan untuk menentukan model prediksi jumlah produksi padi di Kota Mataram pada tahun 2024-2029 dengan menggunakan metode Least Square. Berdasarkan data historis produksi padi dari tahun 2018 hingga 2023, hasil prediksi menunjukkan bahwa produksi padi di Kota Mataram pada tahun 2024 diperkirakan mencapai 16.701 ton dan akan terus meningkat setiap tahunnya, dengan perkiraan mencapai 17.161 ton pada tahun 2029. Tingkat kesalahan prediksi yang sangat rendah dengan menggunakan MAPE sebesar 0,28%, menunjukkan bahwa model ini sangat akurat dan dapat digunakan sebagai dasar perencanaan dan pengambilan keputusan untuk masa depan.

Abstract

The Community Service Program (KKN) of Mataram University in Bonjeruk Village aims to address the issue of plastic waste management by educating the community on utilizing waste into economically valuable products. One of the proposed solutions is training in the production of lightweight bricks made from plastic waste mixed with fly ash from the Jeranjang Steam Power Plant (PLTU Jeranjang). The activities are carried out through a participatory approach, involving the community in various stages, including an initial survey, socialization, training, mentoring, as well as documentation and publication. The brick-making process includes burning plastic waste, mixing it with fly ash and used oil, molding, cooling, and drying before it is ready for use. The results of this program indicate that processing plastic waste into lightweight bricks can be an innovative and sustainable solution for reducing waste while also providing economic opportunities for the people of Bonjeruk Village.
