Abstract

Fruit waste management has gained increasing attention as an eco-friendly approach to sustainable agriculture. The increasing accumulation of organic waste, particularly from fruit residues, poses a significant environmental challenge. Utilizing these waste materials for agricultural purposes can contribute to waste reduction and soil fertility improvement. This study aimed to evaluate the effects of orange and tomato juice application on the growth and yield of potato plants (Solanum tuberosum L.), considering the potential of fruit waste as an organic fertilizer. A Randomized Block Design (RBD) was employed with two treatments: orange juice and tomato juice, each at five concentration levels (0%, 25%, 50%, 75%, and 100%) with three replications, totaling 75 samples. The parameters observed included the number of leaves, stem height, number of tubers, and tuber weight. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT). The results indicated that orange juice significantly increased leaf number, stem height, and tuber weight, while tomato juice had a limited effect. No significant interaction was observed between the two treatments. These findings highlight the potential of fruit waste as an alternative organic fertilizer for sustainable agriculture.

Abstract

Indonesia is known as a country that has very abundant biodiversity, one of which is moss. Mosses are non-vascular plants, small in size, and play a crucial role in forest ecosystems as pioneer plants, water reservoirs, erosionreducers, bioindicators, andmedicinal resources. Theresearchaims tocollect data and information regarding liverwort species in Deli Serdang Regency, North Sumatra, specifically focusing on sampling points along rivers and waterfalls as potential habitats for liverwort life. Thalloid liverwort sampling was conducted using an exploratory survey method, which involved exploring along the courseof rivers and waterfalls. The research findings revealed 6 species of liverworts, consisting of 3 genera and classified into 2 families: Marchantiaceae (Marchantia with 4 species, Dumortiera with 1 species) and Metzgeriaceae (Metzgeria with 1 species). Commonly found species at the location include Dumortiera hirsuta, Marchantia paleacea, and Metzgeria, while the least encountered species are Marchantia treubii, Marchantia pinnata, and Marchantia emarginata.

Abstract

This study aims to analyze what anti-microbial power contained in plants and starfruit plants, and compare which plants are stronger anti-microbial power. The method used in this study is an experimental method, with Escherichia coli bacteria as a representative of disease-causing bacteria. The data obtained were analyzed using the ANOVA test. Based on the results of the study, the stems and leaves of the plant leaves and leaves of star fruit positive containing the composition of secondary metabolites saponins that have antimicrobial power that utilizes the growth ability of E coli. The average diameter of inhibitory zones of plant extracts of wake-up and starfruit ≥ 21 mm, so it is categorized as having strong antimicrobial power. However, the inhibitory zones formed have not been able to match or beat the inhibition zones C 25% (52.54 and 43.1), ciprofloxacin (64.41), which is antibiotics sold on the market that are made with positive control.

Abstract

Medicinal plants have long been used in traditional medicine as part of healing and disease prevention practices. The Malay ethnic group possesses inherited ethnobotanical knowledge regarding the use of medicinal plants. This study aims to identify the types of plants used as medicine and their applications by the Malay community in Bagan Percut Village, Percut Sei Tuan District, Deli Serdang Regency, North Sumatra. A qualitative and quantitative descriptive approach was employed through interviews with 50 respondents and 10 key informants possessing local knowledge of medicinal plants. The results revealed 65 medicinal plant species belonging to 35 sukues, with the dominant ones being Zingiberaceae (6 species), Solanaceae (5 species), and Fabaceae (5 species). The most frequently used plant parts were leaves (46%), fruits (28%), and rhizomes (9%). The most common method of preparation was boiling (29%), while the most common mode of use was oral consumption (48%). Herbaceous plants constituted the most utilized growth form (31%). The purposes of plant utilization included treatment (61.53%), care (24.6%), and general health improvement (13.8%). This study highlights the importance of preserving traditional ethnobotanical knowledge among the Malay community.

Abstract

Virgin Coconut Oil (VCO) merupakan minyak yang diperoleh dari ekstraksi kelapa segar dan diproses dengan berbagai cara, termasuk metode produksi tradisional di rumah. Tujuan pembuatan VCO dan pliek-u yaitu untuk memberikan informasi tentang pemanfaatan produk kelapa berupa santan yang dapat diolah kembali menjadi minyak VCO, dan ampas minyaknya digunakan sebagai pliek-u sebagai makanan tradisional. VCO memiliki nilai jual yang tinggi dan berkhasiat obat. Pliek-u terbuat dari ampas kering sisa minyak kelapa tua. Kedua produk ini dibuat dengan mitra melalui praktik langsung. Hasil yang diperoleh dari pembuatan VCO adalah memiliki sifat fisik yang baik yaitu bening seperti air, memiliki aroma yang harum dan rasa yang dapat diterima, serta bebas dari bau tidak sedap. Pliek-u merupakan alternatif pengganti buah kelapa dan makanan tradisional yang harus dilestarikan. Pliek-u biasanya ditambahkan sebagai bumbu masakan kari, sehingga memberikan rasa yang unik dan otentik. Hasil uji organoleptik pliek-u yaitu warnanya coklat, rasanya asam dan aromanya tidak berbau.
