Abstract

This study aims to determine the growth response of Katokkon chili plants to the administration of shallot extract. This type of research is an experiment using a quantitative approach method carried out in the form of experiments arranged in a Completely Randomized Design (CRD). This design is carried out with a single treatment consisting of 5 treatment levels, the treatment codes to be tested are: B0: control / no treatment, B1: 7% shallot extract, B2: 14% shallot extract, B3: 21% shallot extract and B4: 28% shallot extract which treatments were repeated 3 times so that there were 15 experimental arrangements. The parameters observed were plant height, number of leaves and stem diameter. Data analysis used the ANOVA test and continued with the BNT test. The results showed that the shallot extract treatment had a significant effect on the growth of Katokkon chili plants in the parameters of plant height and number of leaves. The best treatment was obtained at a concentration of 14% and had no significant effect on stem diameter.

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.
