Effects of Vermicompost on Soil Physical Properties, Organic Carbon Content, and the Growth, and Yield of Carrot (Daucus carota L.) on Inceptisols
Get PDFCarrot (Daucus carota L.) is a root vegetable cultivated year-round, particularly in subtropical and highland regions, serving as a vital source of vitamins and minerals. In Indonesia, favorable environmental conditions—such as temperature, rainfall, humidity, and soil type—support carrot cultivation. Among the dominant soil types, Inceptisols are widely distributed but often constrained by low organic carbon content and suboptimal physical properties. However, studies on the long-term effects of organic amendments, particularly vermicompost, on soil quality and crop performance in highland Inceptisols remain limited. This study evaluated the effects of long-term vermicompost application on selected soil physical properties, organic carbon content, and the growth and yield of carrot plants cultivated on Inceptisols. The experiment was conducted from November 2023 to February 2024 in Air Duku Village, Selupu Rejang Subdistrict, Rejang Lebong District, at an altitude of 1,054 meters above sea level. The site had received vermicompost applications for nine consecutive years. A randomized complete block design (RCBD) was employed, with five vermicompost doses (5, 10, 15, 20, and 25 tons ha⁻¹), each replicated three times, resulting in 15 experimental plots. Soil and plant analyses were performed at the Soil Science Laboratory, Faculty of Agriculture,University of Bengkulu.Application of 15 tons ha⁻¹ vermicompost significantly improved pF1 (37.89%), soil organic carbon content (4.15%), and root weight per plant (198.68 g). The 20 tons ha⁻¹ dose significantly increased soil permeability (6.17 cm h⁻¹) and total plant weight (36.17 kg plot⁻¹), while 25 tons ha⁻¹ enhanced water retention at pF2 (43.95%) and pF3 (39.63%). These findings demonstrate the potential of vermicompost to improve soil quality and carrot productivity in highland Inceptisols and support its integration into sustainable vegetable farming systems.

Trait Evaluation of 9 Bird’s Eye Chili (Capsicum frutescens L.) Hybrids on Coastal Area
Get PDFSoil in coastal areas are less suitable for agriculture due to various constraints causing low soil fertility. Until now, there has been no available bird’s eye chili variety tolerant to coastal stress conditions. This research aims to characterize nine bird’s eye chili hybrids grown on coastal land. The research was conducted on coastal land in Kuala Alam Nusa Indah, Ratu Agung District, Bengkulu, from August 2024 to February 2025. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replications. The traits observed consisted of both quantitative and qualitative variables related to bird’s eye chili growth and yield. Quantitative data were analyzed using ANOVA at a 5% and 1% significance level, followed by a Scott-Knott test, α = 5%, to assess data grouping. Qualitative data were descriptively analyzed by comparing with reference to the descriptor for capsicum. The results showed that the tested hybrids differed in all traits. The results showed that the hybrid H3 (A11 × A7) showed the highest production potential with long fruit and large yields despite slower days to flower and a small stem diameter, while hybrid H8 (A39 × A29) excelled more equally in most traits, including fast days to flower, highest plant height and dichotomous height, large stem diameter, large number of branches, high leaf greenness, long fruit with large diameter, and a high fruit weight. Overall, H3 and H8 bird’s eye chili hybrids are potential to be adapted varieties to coastal areas with improvements in several characteristics.

Pengaruh Model Project Based Learning (PjBL) Terhadap Sikap Peduli Lingkungan Siswa Kelas V di SDN Kota Bengkulu
Get PDFThis study aims to determine the effect of using the Project Based Learning (PjBL) model on the environmental care attitude of fifth-grade students in elementary schools in Bengkulu City. This research employed a quantitative approach with a quasi-experimental method and a Matching Only Pretest-Posttest Group Design. The research population included SDN 69, SDN 71, SDN 72, SDN 88, SDN 89, and SDN 103 in Bengkulu City. The sample consisted of fifth-grade students from SDN 69 (experimental group) and SDN 71 (control group). The instrument used was a questionnaire on environmental care attitudes administered through pretests and posttests. Data were analyzed using descriptive statistics, prerequisite tests, and t-tests. The results showed that the t-count (2,807) > t-table (2,004) and the Sig. (2-tailed) value of 0,007 < 0,05. The average score of environmental care attitude in the experimental group was 44,10, while the control group scored 40,88. This indicates a significant difference in posttest results between the two groups, caused by the different treatments. The experimental class applied the PjBL model with a real project such as ecobrick making, which provided hands-on experience and was more effective in shaping environmental care attitudes compared to the control class that only used the PBL model without a real project. Thus, it can be concluded that the PjBL model has an effect on the environmental care attitude of fifth-grade students in elementary schools in Bengkulu City
