Abstract

GDM liquid organic fertiliser is an organic-based fertiliser or nutrient that contains complete nutrients according to plant needs. This study aims to describe information on the effect of GDM liquid organic fertiliser on shallot plants of Palu Valley variety and determine the best dose in its use. This research is an experimental study using a completely randomised design (CRD), consisting of 5 treatments with 4 replications. The treatments consisted of P0 = Control (without fertiliser), P1 = 2 ml/polybag, P2 = 4 ml/polybag, P3 = 6 ml/polybag, P4 = 8 ml/polybag. Data analysis used ANOVA test and continued with BNT test. The results showed that the treatment of GDM liquid organic fertiliser had a significant effect on the growth of shallot plants of Palu Valley varieties, and the best dose for plant growth was P3= 6 ml/polybag. The results of this study were then utilised as a learning resource in the form of a practical guidebook. Based on the validation test and trial on students, the results of the research can be utilised declared feasible as a learning resource with an average percentage of assessment results of 89.34%.

Abstract

This study aimed to identify mangrove species occurring in Kaili Beach, Boyantongo Village, South Parigi District. The research employed a descriptive method with a qualitative approach using a field exploration survey. Species identification was conducted based on observations of morphological characteristics, including roots, stems, leaves, flowers, and fruits, supported by measurements of environmental physical parameters such as air temperature (28 °C), salinity (32 ppt), soil pH (7), water pH (6.2), and relative humidity (72% RH). The results revealed that the mangrove vegetation at Kaili Beach comprised five orders, namely Malpighiales, Myrtales, Lamiales, and Sapindales, and four families, including Rhizophoraceae, Lythraceae, Acanthaceae, and Meliaceae. A total of eight mangrove species were identified: Rhizophora apiculata Blume, Rhizophora mucronata Lamk., Ceriops tagal (Perr.) C.B.Rob., Bruguiera gymnorrhiza (L.) Lamk., Sonneratia alba Smith., Avicennia marina (Forsk.) Vierh., Xylocarpus moluccensis Pierre., and Xylocarpus granatum J. Koenig. The presence of these mangrove species indicates that the physical and chemical parameters of Kaili Beach remain within the ecological tolerance range for mangrove growth. However, the slightly acidic water pH (6.2) suggests that habitat conditions are not yet fully optimal.

Abstract

This study aimed to identify and describe the plant species found on the grounds of SMP Negeri 2 Lakea, Buol Regency, and to develop a digital pocketbook in flipbook format as a contextual learning medium based on local biological resources. An exploratory descriptive method was employed, combining qualitative analysis for plant identification with descriptive quantitative analysis for media validation. Data were collected through surveys and systematic field exploration, direct observation, documentation, and plant identification based on morphological characteristics using relevant literature. The developed medium was validated by content, media, and instructional design experts and evaluated through responses from 30 seventh-grade students at SMP Negeri 2 Lakea. The study identified 35 plant species belonging to 20 families and representing four growth forms: herbs, shrubs, bushes, and trees. The recorded species included ornamental, medicinal, and shade plants, as well as naturally occurring wild species. These findings indicate that the school environment has substantial biological resource potential that can be utilized as a contextual learning resource. Based on student responses, the digital pocketbook was considered practical, concise, interactive, and helpful for understanding the learning material. The feasibility assessment yielded scores of 80% from the content expert, 83% from the media expert, 87% from the design expert, and 91% from student responses. The overall mean score was 85%, placing the medium in the highly feasible category. Therefore, the digital pocketbook based on plant diversity at SMP Negeri 2 Lakea is suitable for use as a contextual learning medium integrating local biological potential.

Abstract

This study aimed to evaluate the effectiveness of liquid organic fertilizer (LOF) derived from coconut husk on the vegetative growth of bird’s eye chili (Capsicum frutescens) using a completely randomized design (CRD). The experiment consisted of five treatment levels with four replications, resulting in a total of 20 experimental units. The treatments included P0 (control), P1 (10%), P2 (15%), P3 (20%), and P4 (25%), each applied at a volume of 250 mL per application on 14, 28, and 42 days after planting. Plant height and the number of leaves were measured at 21, 35, and 49 days after planting. The data were analyzed using normality and homogeneity tests, analysis of variance (ANOVA), and the least significant difference (LSD/BNT) post hoc test. The results demonstrated a highly significant effect of coconut husk-based LOF application, with p-values of 0.002 for plant height and <0.001 for the number of leaves. Among the tested treatments, the 15% LOF concentration (P2) exhibited the most optimal effect in promoting the vegetative growth of bird’s eye chili.

Abstract

This study aimed to analyze the effect of collaborative project-based learning (PjBL) on students’ communication skills at SMP Negeri 4 Palu. A quasi-experimental nonequivalent control group design was employed, involving 22 students in the experimental group and 24 students in the control group selected through cluster random sampling. The intervention was implemented through a contextual project, the Eco-Soil Poster Campaign, which involved creating a digital poster campaign promoting soil health conservation within the school environment. Data were collected using a posttest communication skills questionnaire, while a cognitive pretest was administered to verify the initial equivalence of the two groups. The instrument was validated using Aiken’s V and Cronbach’s Alpha. The results revealed a significant difference between the two groups (p = 0.018 < 0.05), with the experimental group achieving a higher mean score (75.64%, categorized as Good) than the control group (69.83%, categorized as Fair), accompanied by a moderate effect size (Cohen’s d = 0.724). These findings indicate that collaborative PjBL significantly improves students’ communication skills and can be recommended as an effective instructional strategy for junior high school biology learning.
