Abstract

Monkey pest attacks pose a serious threat to agricultural productivity, particularly affecting the Tunas Baru Farmers Group. This study aims to implement appropriate technology to mitigate crop damage caused by these pests. The activity was conducted in Rempang Cate Ward from May to September 2025. The implementation method included field observation, system design (hardware and software), on-site installation, as well as monitoring and performance evaluation. The developed device utilizes a Convolutional Neural Network (CNN) with a Raspberry Pi microcontroller and a webcam to detect the presence of monkeys within a radius of up to 35 meters. Upon detection, the system automatically generates a gunshot sound audible up to a radius of 250 meters to repel the pests. Given that the partner's location lacks access to the PLN electricity grid, the device is powered by solar panels as a renewable energy source. The implementation results demonstrate a significant impact, marked by a reduction in crop damage from an average of nine trees to only three trees per attack incident. This reduction contributed to a 67% increase in production yield compared to the pre-installation period. This technology has proven to be a more effective and efficient solution than manual guarding methods and has the potential to be replicated in other areas to support food security and rural welfare.

Abstract

Currently, motorcycles are the maximum extensively used approach of transportation in Indonesia. apart from being a way of transportation and for delivering items, of direction, it has unique settings from motorbikes which might be used for daily purposes via making overall performance upgrades by using modifying the noken axle (camshaft) on motorbikes which are used each day. The characteristic of the camshaft is to manipulate the valve opening, both the consumption and exhaust valves at the time decided with the aid of the four stroke engine cycle. at the changed engine, numerous adjustments have been made to several systems and components to improve the performance of the bike. The cause of this take a look at become to determine the performance of the Honda Absolute revo 110cc combustion engine which incorporates torque, strength and gasoline intake with the aid of comparing the standard camshaft and The changed camshaft which has modified the lift top by using 1mm has changed in the absolute revo 110cc engine, adjustments occur amongst them in torque, energy and greater gasoline intake enter the combustion chamber. The studies was received from a tool which can decide power called Dynotest. Dynotest serves to measure the torque strength of a motorcycle that has been modified by means of camsaft so as to understand better which is the modified camasafth and the usual camsafth on a 110cc revo absolute motorcycle.
