Abstract

CO2 flux from peat soil planted with oil palm is temporally and spatially dynamic, which is related to various environmental factors. This flux can be partitioned into fluxes from oil palm root respiration, litter decomposition, and peat material decomposition. The aim of this study was to determine the temporal and spatial dynamics of CO2 fluxes, the contribution of oil palm roots respiration, the contribution of litter decomposition, and the relation between flux and environmental factors in oil palm plantations on peatland. Measurements of CO2 flux using an infrared gas analyzer (IRGA) were carried out in harvesting path and inter raw of oil palm plantation, and nearby bushland. Flux measurements were repeated every three to four days for almost five months. Results showed the dynamics of the CO2 fluxes temporally and spatially. Temporally, CO2 flux in oil palm plantation and bushland ranged from 2.9 – 11.1 and 0.5 – 6.4 g C-CO2 m2/day, respectively. Spatially, the flux in oil palm plantation and bushland ranged from 4.8 – 8.8 and 2.7 – 3.4 g C-CO2 m2/day, respectively. The contribution of oil palm roots respiration and litter decomposition were 48.4 and 5.8%, respectively. These results confirm that plant roots respiration plays an important role in the release of carbon from the soil surface.

Abstract

The Edu-Eco-School Program was implemented as a community service activity at SMPS Khazanah Boarding School, Pujud District, with the aim of optimizing school land through the cultivation of food crops and vegetables supported by a water-efficient irrigation system. This program is significant as it aligns with the Sustainable Development Goals (SDGs), particularly Zero Hunger and Climate Action, which emphasize food security and water resource conservation in education. The implementation stages included land condition surveys, the design and construction of a bore well and PVC pipe network as an irrigation system for plant watering, agricultural training, and mentoring up to the harvesting stage. The program successfully transformed underutilized land into a productive garden with various commodities, such as chili, tomato, corn, and vegetables. The harvest not only met the school’s basic needs but also served as a contextual learning medium for students to practice sustainable agriculture. Overall, this program enhanced school community engagement, improved water-use efficiency, and created a productive green area that supports local food security while strengthening environmental education.

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

National chili demand continues to increase, but productivity at the farmer level remains low due to attacks by the whitefly (Bemisia tabaci Genn.) virus. Benai Kecil Village, Benai District, Kuantan Singingi Regency, Riau, is a horticultural center with low chili productivity (4–5 tons/ha), far below the potential of commonly used superior varieties. This community service activity aims to improve farmers' knowledge and skills in chili cultivation by initiating the use of the superior virus-resistant Neno variety. The program was implemented for five months with stages of socialization, field practice, mentoring, monitoring, evaluation, and follow-up. The results of the activity indicated that farmers improved their understanding and skills in chili cultivation techniques, including seeding, soil cultivation, maintenance, and pest and disease control. The evaluation showed that the Neno chili variety has the potential to be developed because it is adaptive to dynamic climate change and effectively reduces the risk of curly virus attacks. In addition, the use of virus-resistant varieties can also support environmentally friendly pest and disease control. This program demonstrates that the development of the superior Neno variety has the potential to be a sustainable strategy for increasing chili production while simultaneously strengthening food security and farmer welfare.

Abstract

This community service program aims to improve farmers' knowledge and skills in cultivating chili plants and preventing geminivirus infection, a major constraint in production. The activity was carried out through outreach activities covering the stages of land cultivation, virus infection prevention techniques, whitefly population control as a vector, land clearing of weeds that are hosts of geminivirus, sanitation of infected plants, and proper pesticide use. In addition, participants were also introduced to the use of chili varieties resistant to the yellow geminivirus as an alternative sustainable solution. The results of the activity showed an increase in farmers' understanding of healthy cultivation strategies and integrated pest control, with an average score increasing from 45% to 85%, with the vector control aspect increasing from 30% to 90%. This outreach is expected to reduce the level of virus infection and increase chili productivity.

Abstract

Lahan gambut memiliki peran penting dalam ekosistem, namun sangat rentan terhadap degradasi akibat perubahan penggunaan lahan dan kebakaran. Penelitian ini bertujuan untuk mengevaluasi karakteristik fisik tanah gambut pada penggunaan lahan kelapa dua tipe penggunaan lahan gambut di Pulau Burung, Indragiri Hilir, Riau, yaitu lahan perkebunan kelapa dan lahan gambut terbakar yang telah berkembang menjadi semak belukar. Contoh tanah diambil dari kedalaman 0–20 cm dan 20–40 cm, lalu dianalisis untuk parameter fisik tanah. Analisis deskriptif-komparatif menunjukkan bahwa lahan perkebunan kelapa memiliki sifat fisik tanah yang berbeda, dengan bobot isi rendah (0.18-0.11 g/cm³), kerapatan partikel <1 g/cm³, dan porositas tinggi (80–84%). Sebaliknya, lahan semak belukar bekas terbakar menunjukkan peningkatan bobot isi dan kerapatan partikel. Perbedaan ini mencerminkan dampak dari kebakaran, serta manajemen dari perkebunan kelapa. Hasil penelitian menekankan pentingnya pengelolaan lahan gambut yang berkelanjutan tanpa kegiatan pembakaran.

Abstract

Eggplant (Solanum melongena L.) is a widely consumed vegetable in Indonesia, both as a fresh salad and in various prepared dishes. This vegetable is rich in nutrients, particularly vitamin A and phosphorus, and can help improve the nutritional diversity of the population. In Riau Province, average eggplant productivity has declined, necessitating improvements to the production system to meet steadily rising demand. This study aims to investigate the interaction between earthworm application and cabbage residue and to identify the combination that produces the best eggplant plants. The experiment used a factorial Completely Randomized Design (CRD) with two factors. The first factor was earthworm application (0, 20, and 30 earthworms per polybag). The second factor was cabbage residue application (0, 420 g, and 630 g per polybag). The observed parameters included plant height, days to flowering, days to first harvest, fruit length, fruit diameter, and fruit weight. The data were statistically analyzed using analysis of variance (ANOVA); if the calculated F-value exceeded the table F-value, the analysis continued with Duncan's New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that there was no significant interaction between the two factors for any of the observed parameters. However, individually, the application of 30 earthworms and 630 g of cabbage waste tended to produce the best growth and yield. Based on the research results, it is recommended to use a combination of 30 earthworms and 630 g of cabbage waste.
