Abstract

The problem of kitchen waste, such as vegetable and fruit scraps, in urban areas is increasing with population growth and urbanization in various cities in Malaysia. Furthermore, organic waste such as rice washing water (leri water) is generally discarded, despite its great potential as a raw material for Local Microorganisms (LMICs) in the production of liquid organic fertilizer from kitchen waste. This community service article aims to describe the innovation of processing leri water into environmentally friendly liquid organic fertilizer from kitchen waste through training. This program was implemented at the Muhammadiyah Kepong Guidance Center, Kuala Lumpur, Malaysia, in January 2026. The methods used were outreach and the production of Leri water MOL. The results of the activity showed an increase in the knowledge and skills of children at the Muhammadiyah Kepong Guidance Center in processing kitchen waste into useful organic fertilizer, supporting household food security, and reducing urban organic waste.

Abstract

Lettuce (Lactuca sativa L.) is a horticultural commodity widely cultivated using hydroponics due to its economic value and relatively short harvest cycle. However, hydroponic lettuce remains susceptible to insect pest infestations that can reduce both yield quality and quantity. Information regarding the types of pests, infestation levels, and damage symptoms affecting hydroponic lettuce at the Experimental Garden of the Faculty of Agriculture, Universitas Muhammadiyah Palembang, remains limited; thus, field data is required to inform pest management strategies. This study aimed to identify insect pests and determine their infestation levels on hydroponic lettuce plants at the Experimental Garden of the Faculty of Agriculture, Universitas Muhammadiyah Palembang. The research was conducted between October and December 2025 using a survey method with purposive sampling. The study sample consisted of two lettuce plants monitored over four observation sessions. Direct observations were made to detect the presence of pests and symptoms of plant damage. Collected insects were identified based on morphological characteristics using taxonomic keys. Infestation levels were calculated using the formula: IS = (number of infested plants / total number of observed plants) × 100%. The results revealed the presence of aphids (Aphis sp.) and red spider mites (Tetranychus urticae). Aphids were the dominant pest, with an infestation level of 50%, while T. urticae showed an infestation level of 25%. Observed symptoms included leaf yellowing and stunted growth. The findings indicate that pest presence is associated with environmental conditions and crop sanitation. These data can serve as a basis for implementing integrated pest management in hydroponic lettuce cultivation.
