Abstract

Red chilies are one of the horticultural commodities that have high economic value in Indonesia. Red chili production in Indonesia in 2021 will reach 136 million tons, with Riau province experiencing a decline in production which causes a production deficit in the province. To increase production, it is necessary to improve red chili cultivation techniques. The growth of red chili plants is influenced by internal and external factors, including ideal rainfall ranging from 600 mm/year to 1,250 mm/year. Rainfall that is too high can cause air humidity to increase and plants are more susceptible to disease. Red chili plants also require slightly hot daytime temperatures and sufficient water availability. In the rainy season, the risk of red chili crop failure is high because the plants cannot tolerate standing water. Excess water can cause plant root rot and diseases such as bacterial wilt and anthracnose. Therefore, it is necessary to develop red chili cultivation techniques in the rainy season, such as making the right planting schedule, understanding cultivation techniques, and using technical cultural measures such as making higher beds and using appropriate pesticides. With the right cultivation techniques, it is hoped that it can increase farmers' income and welfare. Red chili cultivation can also provide large profits if revenue is high and production costs are low. Therefore, it is important to optimize efforts to increase red chili production by using appropriate cultivation techniques during the rainy season. The aim of this community service activity is to increase public knowledge about cultivating chili plants during the rainy season in Teluk Piyai Pesisir.

Abstract

Tujuan dari kegiatan pengabdian masyarakat ini yaitu untuk meningkatkan pengetahuan masyarakat tentang budidaya tanaman cabai merah dan kondisi tanah di Teluk Piyai Pesisir. Pengabdian telah dilakukan pada bulan Agustus 2024. Pengabdian dilakukan dengan metode diskusi dan praktik lapangan. Dari hasil diskusi dan praktik lapangan diperoleh permasalahan yang dominan pada petani adalah adalah kondisi tanah yang mengandung phyrite dan tergenang pasang air laut, pengolahan tanah, serta masalah yang tidak terlalu signifikan adalah hama dan penyakit serta masalah panen hingga penjualan cabai merah. Dari hasil diskusi direkomendasikan untuk kedepannya agar petani untuk dapat melakukan pemupukan yang sesuai dosis anjuran dan pada pengolahan tanah untuk tidak terlalu dalam saat mencangkul atau mengolah tanah menggunakan traktor pada kedalaman lebih dari 40 cm sudah terdapat kandungan phyrite yang dapat mengganggu pertumbuhan tanaman dan kondisi tergenang kandungan phyirite lebih mudah tersebar dan larut di permukaan tanah

Abstract

Celery offers a distinctive flavor to culinary dishes and has biopharmaceutical potential in addressing various health issues. Efforts to obtain high-quality celery in terms of appearance and content continue to be made to meet human needs. The objective of the study is to determine the morphological and physiological responses of celery plants to shade treatment and mung bean sprout extract. The experimental design used a completely randomized design with 2 factors, namely the provision of shade (without shade, 65% shade, 75% shade, and 85% shade) and the provision of bean sprout extract (without bean sprout extract, 10% bean sprout extract, and 30% bean sprout extract). Each treatment was repeated 3 times. Data were analyzed by analysis of variance and Duncan's New Multiple Range Test (5%). Results indicated that 85% shading combined with 30% mung bean sprout extract yielded the highest stomatal density. The same extract concentration also produced the highest chlorophyll a and total content. In contrast, 65% shading resulted in the largest leaf area of celery plants.

Abstract

This study aimed to determine the effect of pyrolysis methods on the biochar yield from oil palm empty fruit bunches (EFB) using variations in material form and combustion systems. The research was conducted from March to May 2025 in Sorek Satu, Pelalawan Regency, Riau Province, and in the Soil Science Laboratory, Faculty of Agriculture, Riau University. The study consisted of several treatments: (1) whole EFB – external semi-vacuum combustion, (2) shredded EFB – external semi-vacuum combustion, (3) whole EFB – total internal vacuum combustion, and (4) shredded EFB – total internal vacuum combustion. Collected data from the study were analyzed using descriptive statistics. The results showed that external semivacuum pyrolysis produced a higher biochar yield compared to total internal vacuum pyrolysis, with the highest yield from whole EFB at 45.6% and shredded EFB at 32.8%. The total internal vacuum system failed to produce biochar and only resulted in dry material without undergoing carbonization. The chemical characteristics from the external semi-vacuum combustion system indicated that biochar from whole EFB had higher contents of carbon, potassium, magnesium, boron, and pH, while biochar from shredded EFB tended to have higher contents of nitrogen, calcium, and iron.

Abstract

Anthracnose is one of the main diseases in chili plants that causes a decrease in the quality and quantity of the harvest. This study aims to identify anthracnose disease in red chili (Capsicum annuum) and cayenne pepper (Capsicum frutescens) in Agrowisata Village, West Rumbai District. Observations were made through observation of symptoms in the field, pathogen isolation, and identification of colony and conidia morphology. The results of the observations showed the presence of typical anthracnose symptoms in the form of circular necrotic spots, dark sunken lesions, and rot on the fruit. Pathogen isolation on PDA media showed variations in colony color in both isolate sources, namely gray and peach in red chili and white and gray in cayenne pepper. Microscopic observations showed cylindrical conidia with both ends fusiform, according to the characteristics of Colletotrichum acutatum. Thus, it can be concluded that anthracnose disease in both types of chili is caused by C. acutatum. These findings are expected to be the basis for developing a more effective and sustainable disease control strategy for chili cultivation in the region.

Abstract

The success of mung bean (Vigna radiata L.) cultivation is determined by the quality of the seeds used. One effort to improve seed quality is through biopriming techniques based on natural ingredients. The purpose of this study was to evaluate the potential of shallot (Allium cepa L.) extract as a biopriming agent in increasing the viability and vigor of mung bean seeds, and to determine the optimum effective concentration. This study was conducted at the Ecophysiology Laboratory, Department of Agrotechnology, Faculty of Agriculture, University of Riau. The experimental design in this study was a completely randomized design (CRD) with one factor with six levels of shallot extract concentration, namely 0% (control), 5%, 10%, 15%, 20%, and 25% with four replications. The observation parameters consisted of germination power and germination rate, vigor index I and II, hypocotyl length, root length, fresh weight, and dry weight of the sprouts. Data analysis used ANOVA and Duncan's advanced test at the 5% level, and was supplemented with effect size analysis with eta-squared (η²). The results showed that 15% extract concentration was the optimum concentration in increasing germination rate and vigor II index. Germination rate and vigor II index decreased in direct proportion to the increase in extract concentration. The application of shallot extract had no significant effect on germination rate, hypocotyl length, root length, dry weight, and fresh weight of mung bean sprouts.
