Abstract

This study aimed to evaluate the effects of applying solid compost and coal fly ash on the improvement of Ultisol chemical properties and to determine the optimal dosage for its application. Ultisol, known for its high acidity, low organic matter content, and limited nutrient availability, requires specific amendments for optimization. The study was conducted using a factorial completely randomized design (CRD) with 12 treatment combinations: four levels of solid compost (0 t.ha-1, 2,5 t.ha-1, 5 t.ha-1 dan 7,5 t.ha-1) and three levels of fly ash (0 t.ha-1, 3 t.ha-1 and 6 t.ha-1), each with three replications. The soil that has been treated is incubated for two weeks, then the chemical properties of the soil are analyzed. The results showed that the combination of solid compost and fly ash significantly improved Ultisol chemical properties, including increasing soil pH, reducing Al-dd levels, and enhancing P-available, organic carbon (organic C), total nitrogen (total N), cation exchange capacity (CEC), and total potassium (total K). The combination of 7,5 t.ha-1 solid compost and 6 t.ha-1 fly ash provided the best results, achieving a soil pH of 5.15, an increase available P to 23.7 ppm, and a high CEC level. This combination effectively improved Ultisol quality, making it more supportive for plant growth.

Abstract

Gold snail (Pomacea canaliculata L.) is the main pest of rice plants in Empat Balai Village, Kuok District, Kampar Regency. Farmers in Empat Balai Village experience gold snail infestation every year, which has an impact on production. The purpose of community service activities is to conduct community service by counseling and controlling carp pests in rice fields by utilizing local wisdom in Empat Balai Village. The methods in this service are survey, consolidation, counseling and field practice. The counseling was held at Mushallah Miftahul Jannah in Pulau Empat Hamlet, while the field practice was at the farmer’s house and rice fields in Empat Balai Village. The material provided was about bioecology and how to control the carp snail pest. It was emphasized that the recommended control carp pests are the management of carp pests in the egg phase, because one group of eggs has 500 eggs and control is easier in the egg phase. Control in the egg phase includes making drainage or small ditches, installing bamboo stakes so that the snails lay their eggs there, and collecting the eggs once a week. In the snail phase, involves setting up attractant plant traps (gadung tuber leaf, papaya leaf, and banana leaf), kalambuai traps (kaltrap), installing of irrigated nets, utilizing ducks, and vegetable molluscicides. In addition, preventive measure was taken, such as planting older seedlings. The farmers were very enthusiastic about this activity. As a result, farmers gained additional knowledge about gold snail pests and how to control them, improve farmers skills on gold snail pests control methods by utilizing local wisdom.

Abstract

This research was conducted with the aim of studying the effect of the interaction of solid compost with coal fly ash and each treatment, as well as to obtain the best dose in increasing the growth and yield of upland rice plants (Oryza sativa L.) on Podsolic medium (Ultisol). The study used an experimental method with a completely randomized design (CRD) factorial of two factors, namely the provision of solid compost (0; 2.5; 5; and 7.5 t.ha-¹) and coal fly ash (0; 3; and 6 t.ha-¹) so that 12 treatment combinations were obtained with three replications, totaling 36 experimental units. The soil used was Ultisol soil from Batu Belah Village, Kampar. Observations included growth parameters and yields of upland rice plants of the Inpago 12 variety which included: plant height, maximum and productive number of tillers, panicle emergence age, harvest age, number and percentage of full grain, weight of 1,000 full grain grains, and weight of dry milled grain per clump. The research data were analyzed using analysis of variance (ANOVA) and continued with the Duncan Multiple Range Test (DMRT) at the 5% level. The study showed that there was no interaction between solid compost and coal fly ash on the growth and yield of upland rice (Oryza sativa L.) on Podsolic soil (Ultisol). Solid compost significantly affected several parameters such as plant height, panicle emergence age, harvest age, percentage of full grain, weight of 1000 full grain grains, and weight of dry milled grain per clump with the best dose of 5 t.ha-¹. On the other hand, coal fly ash did not show any significant effect on all observed parameters. Therefore, solid compost at a dose of 5 t.ha-¹ is recommended to increase the growth and yield of upland rice variety Inpago 12 on Podsolic soil (Ultisol).

Abstract. Hamzah A, Saputra R, Puspita F, Nasrul B, Irfandri, Depari NS. 2021. Ganoderma diversity from smallholder oil palm plantations in peatlands of Kampar District, Indonesia, based on mycelia morphology and somatic incompatibility. Biodiversitas 22: 16-22. Basal Stem Rot disease is caused by the pathogenic fungus Ganoderma boninense which has caused major economic losses in the palm oil industry. Ganoderma boninense has been reported not only infecting crops in the field, but also attacking at the immature phase of the plant even in the nursery. Studies related to Ganoderma diversity in oil palm plantations in Riau, Indonesia have not been widely reported. Ganoderma genetic diversity is important because its provide information regarding the mechanism of infection and the spatial distribution. The Ganoderma spp. isolates were collected from three blocks of smallholder oil palm plantation in Deli Makmur Village, Kampar District, Riau Province, Indonesia and brought to Plant Disease Laboratory, Faculty of Agriculture, Riau University, Pekanbaru, Indonesia. This experimental research was conducted using six Ganoderma isolates (Gan1, Gan2, Gan3, Gan4, Gan5, and Gan6) on the parameters of colony diameter and growth speed, while for the parameters of the morphological diversity of Ganoderma mycelium and the diversity based on somatic incompatibility assay was carried out descriptively. The results of this study show that oil palm plants in smallholder plantations in Kampar District are infected by two groups of Ganoderma based on morphology characteristics using UPGMA dendrogram, but different among isolates based on genetically using somatic incompatibility assay. For the next confirmation, it is necessary to further identify whether the six isolates are different species using molecular identification.

Abstract

Oil palm is a plantation commodity that plays a strategic role in the economic development of Kampar Regency. Sungai Pagar Sub-district, located in Kampar Kiri Hilir District, Kampar Regency, Riau Province, is an area where the majority of the population works as oil palm farmers. Cultivation activities in managing oil palm plantations are accompanied by an abundance of palm oil waste, particularly Empty Fruit Bunches (EFB). This waste is often considered an environmental problem due to its large volume and potential for pollution. Therefore, it needs to be processed into beneficial products such as organic fertiliser to support sustainable agriculture. This programme aimed to provide education and training on the production of vermicompost, thereby increasing public knowledge on managing oil palm EFB waste in an environmentally friendly and economically valuable way. The implementation methods included dissemination of information on vermicomposting, technical training and mentoring, and evaluation through pre- and post-tests. The training involved 25 participants. The results of the community engagement activity demonstrated a significant increase in participants’ knowledge regarding the use of palm fronds. Evaluation showed a notable improvement in understanding, application, and programme impact, with scores rising from an average of 38.96% in the pre-test to 100% in the post-test. Overall, this activity enhanced the awareness of Kampung Sialang Sakti residents regarding the transformation of EFB waste into vermicompost by 62.04%, from 38.96% to 100%.
