Abstract

Lampung Province has great potential in developing horticultural commodities, particularly chili (Capsicum frutescens L.), which is a strategic commodity for farmers’ livelihoods and national food price stability. However, chili production in Lampung often fluctuates due to seasonal factors, climate change, pest attacks, limited farmer capital, and market conditions. This study aims to forecast chili production in Lampung Province using POM-QM software with the Linear Regression method based on historical production data from 2020–2023 obtained from BPS. The data were processed using POM-QM version 5 to predict production for the 2024–2027 period. The results indicate that the most appropriate forecasting method for predicting cayenne pepper production in Lampung Province was Linier Regression, as it produced the lowest Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE) values, namely 1,192.25 and 9.76%, respectively. The linear regression model obtained was y = 1080.9x – 2E+06, with a coefficient of determination R2 of 0.7503, indicating that the model adequately explained the variation in production data. Based on this model, the forecasted cayenne pepper production in 2027 is 12,488

Abstract

Negarasaka Village, located in Negeri Katon Subdistrict, Pesawaran Regency, Lampung Province is an area with high agricultural potential through its farming and livestock sectors. However, livestock activities generate significant waste, which, if not properly managed, can lead to environmental pollution. The utilization of livestock manure as compost has not been optimized, prompting the implementation of a socialization and workshop program on compost-making to improve community knowledge in Negarasaka Village. This activity involved 30 participants and employed methods such as material presentation, hands-on practice, and evaluation through pre-test and post-test to measure the effectiveness of the socialization program using questionnnaires. The result showed an increase in participants knowledge about compost by 77-100% regarding the concept, benefit and methods of compost produstion.
