Kuantan Singingi Regency is one of the ruminant-producing districts in Riau Province. Koto Simandolak Village, located in Benai District, Kuantan Singingi Regency, the majority of the people work as farmers. Generally, farmers in Koto Simandolak Village cultivate livestock traditionally, namely by releasing them to the wild. This condition causes several problems including livestock manure, pollution of the village environment, and conflicts with residents. This problem can be solved if the farmer wants to keep the cattle. By holding cattle, the manure will be collected directly in the cage. Animal manure can be processed and used in biogas and organic fertilizer. The Research and Community Services Team of Universitas Riau saw the potential for utilizing livestock manure waste in Koto Simandolak Village. The Team conducts training and assistance in the installation of biogas reactors as well as training and mentoring in the biogas production process using livestock manure. Another output of biogas production is organic fertilizer. The ultimate goal of this service activity is to increase the income of the target community, namely through increasing livestock production, biogas production, and organic fertilizer production.

Ammonia from livestock manure reacts with chemical components discharged from various emission sources to produce airborne particulate matter. This study aimed to investigate a novel effective microbial agent to suppress ammonia gas emitted from manure. Both isolated L12I and 12III strains, identified as Pediococcus acidilactici (PA), were selected for their superior activity in assays performed with the evaluation criteria such as acid production, ammonia decomposition, and urease inhibition, which are key factors influencing ammonia excretion. The survivability of PA strains was confirmed by an increase in DNA abundance in the manure. PA strains lowered the pH of manure and suppressed the growth of hyper-ammonia-producing bacteria (HAB) possessing urease activity. The L12I and 12III treatment groups showed 23.58% and 38.00% emission reductions, respectively. Especially, the 12III strain was proven to be the more effective strain for reducing ammonia gas emission, with the best ability to reduce pH and inhibit HAB. The strains could have an additive effect in improving the manure quality as a nitrogen fertilizer by preserving the total nitrogen and urea content. These results suggest that PA strains can be used as unprecedented microbial agents to improve manure-derived environmental pollution and improve fertilizer quality.

The aim of this review was to provide an update on the complex relationship between manure application, altered pathogen levels and antibiotic resistance. This is necessary to protect health and improve the sustainability of this major farming practice in agricultural systems based on high levels of manure production. It is important to consider soil health in relation to environment and land management practices in the context of the soil microflora and the introduction of pathogens on the health of the soil microbiome. Viable pathogens in manure spread on agricultural land may be distributed by leaching, surface run-off, water source contamination and contaminated crop removal. Thus it is important to understand how multiple pathogens can persist in manures and on soil at farm-scale and how crops produced under these conditions could be a potential transfer route for zoonotic pathogens. The management of pathogen load within livestock manure is a potential mechanism for the reduction and prevention of outbreaks infection with Escherichia coli, Listeria Salmonella, and Campylobacter. The ability of Campylobacter, E. coli, Listeria and Salmonella to combat environmental stress coupled with their survival on food crops and vegetables post-harvest emphasizes the need for further study of these pathogens along with the emerging pathogen Providencia given its link to disease in the immunocompromised and its’ high levels of antibiotic resistance. The management of pathogen load within livestock manure has been widely recognized as a potential mechanism for the reduction and prevention of outbreaks infection but any studies undertaken should be considered as region specific due to the variable nature of the factors influencing pathogen content and survival in manures and soil. Mediocre soils that require nutrients could be one template for research on manure inputs and their influence on soil health and on pathogen survival on grassland and in food crops.

ABSTRAKDesa Bentang Kecamatan Galesong Selatan Kabupaten Takalar merupakan desa yang sebagian besar penduduknya pada sektor pertanian maupun usaha ternak. Namun pada pelaksanaan dilapangan, desa ini belum memanfaatkan hasil alam, dalam hal ini limbah-limbah kotoran ternak maupun pertanian sebagai bahan dasar pupuk organik yang dipergunakan dalam berusahatani. Sehingga pengabdian masyarakat ini bertujuan agar masyarakat Desa Bentang mendapatkan informasi dan pengaplikasian pembuatan pupuk organik padat yang bersumber dari limbah pertanian dan kotoran ternak. Metode pelaksanaan kegiatan masyarakat ini dilakukan dengan beberapa langkah, yaitu: perencanaan, tindakan, observasi dan evaluasi akhir. Hasil kegiatan ini memberikan informasi dan pengaplikasian pembuatan pupuk organik yang bersumber dari limbah pertanian dan kotoran ternak yang nantinya dapat memberikan dampak peningkatan produksi usahataninya.                                                                                                                Kata Kunci: sosialisasi;, aplikasi pupuk organik ABSTRACTBentang Village, South Galesong District, Takalar Regency is a village where most of the populations are in the agricultural sector and livestock business. However, in the implementation of agriculture, that village had not utilized natural products, in this case livestock manure and agricultural wastes as the basic ingredients of organic fertilizer were used in its own agriculture. Thus, this community service aimed to make the people of Bentang Village able to make solid organic fertilizer from compost waste made from livestock manure and agricultural waste to improve agriculture. The method of implementing the had been community activity is carried out in several steps, namely: planning, action, observation and final evaluation. The results of those activities provide information and the application of making organic fertilizers sourced from agricultural waste and livestock manure, which could later have an impact on increasing farm production. Keywords: socialization; application of organic fertilizer

Food waste generated at the consumer level constitutes a gigantic portion of the total amount of food wasted/lost and valorisation is touted as the most sustainable way of managing the generated waste. While food waste valorisation encompasses several methods, composting is the cheapest technique that can produce stabilised carbon-rich soil amendments. The food waste generated at the consumer level, however, is laden with sodium chloride. The compost produced from such waste has the potential of inducing saline and or sodic conditions in the soil, resultantly impeding proper crop growth and yield. Due to the scarcity of plausible means of eradicating sodium chloride from the food waste before composting, the idea of mixing the composted food waste with other low sodium chloride-containing composts to produce a food waste compost-containing amalgam with a high fertiliser potential was mulled in this study. The study then assessed the effects of mixing sodium-chloride-rich food waste compost with the nutritious and low sodium chloride-containing livestock manure composts on the yield and quality of leaf lettuce. Mixing food waste compost with livestock manure composts in the right proportions created mixed composts that produced a higher lettuce yield than both the pure livestock manure composts and food waste compost. The mixed composts also produced leaf lettuce with higher chlorophyll content and, thus, better marketability and lower nitrate content (with higher health value) than the pure livestock manure composts.
