Abstract

The growth of pakchoy is determined by the availability of nutrients around its root system. Research on the effect of bokashi and NPK fertilizer on pakchoy vegetative growth was conducted from May to August 2025. This study aimed to measure the increase in pakchoy growth after being given bokashi and NPK fertilizer. The pakchoy planting experiment was conducted using a completely randomized design with two factors. Pakcoy was planted in experimental pots, given bokashi treatment 3 days before planting and given NPK fertilizer 15 and 22 days after planting. The results of the experiment showed that: (1) the vegetative growth parameters of pakchoy given 1.5 g of NPK fertilizer were significantly different from the control, except for leaf width, (2) the vegetative growth parameters of pakchoy given 1.6 kg of bokashi were significantly different from the control, except for leaf width, (3) The interaction of bokashi and NPK fertilizer did not significantly affect the vegetative growth of pakchoy.

Abstract

Indonesia is recognized as a country rich in biodiversity, boasting an extensive variety of plants and animals. Lombok Island, one of Indonesia's islands, showcases a significant level of biodiversity. This island is home to the Mount Rinjani National Park. Within the TNGR region, Aik Berik Village serves as the designated hiking route for Mount Rinjani National Park, featuring a remarkable variety of plant life, such as orchids and ferns. Nonetheless, studies exploring the orchids and ferns along the Aik Berik hiking path remain scarce, and no one has examined them across different elevations, making this research essential. This study aims to determine the types of orchids and ferns and their distribution on the Aik Berik hiking trail of Mount Rinjani National Park. The method used in this study is the cruise method. The findings of this research identified 14 genera and 24 species of orchids, which include 17 epiphytic orchids and 7 terrestrial orchids, totaling 940 individuals. The orchid with the broadest distribution is Pinalia multiflora, located at altitudes between 1,000 and 2,500 meters above sea level, with a count of 100 individuals. Conversely, the least common species is Dendrobium rindjaniense, which exists at heights of 2,000 to 2,500 meters above sea level, totaling only 5 individuals. The study also discovered 15 families, 22 genera, and 31 species of ferns, comprising 25 terrestrial ferns and 6 epiphytic ferns, amounting to 8,165 individuals in total. The fern species that is distributed the most is Macrothelypteris torresiana, found at altitudes of 1,000 to 2,500 meters above sea level, with 1,150 individuals recorded. In contrast, the species with the least distribution is Huperzia selago, which appears at altitudes between 1,000 and 2,000 meters above sea level, with just 20 individuals present.

Abstract

Forest of Lemor Botanical Gardens in Suela District, Lombok Island, Indonesia, is known for its rich plant diversity, including members of the Moraceae family, which have important ecological and economic values. Existing records of Moraceae in this area are primarily based on botanical collections from the ex-situ zone, whereas information on species occurring in the in-situ forest conservation area remains limited. Therefore, this study was conducted to explore and identify species of the Moraceae family present in the forest area of Lemor Botanical Gardens. The research applied a descriptive exploratory approach using purposive sampling and the cruise method during field surveys conducted from September to November 2025. Data collection included counting individual plants, photographic documentation, morphological description, and voucher specimen verification. The study recorded sixteen species belonging to four genera in the Moraceae family, namely Ficus, Artocarpus, Streblus, and Morus, with a total of 805 individuals. Among these, Ficus septica was the most abundant species, with 125 individuals recorded, making it the dominant species in this habitat. These findings provide preliminary baseline data that can support conservation management of the area, complement the need for in-situ data, and document Moraceae botanical collections that had not previously been recorded within the ex-situ area of the botanical garden. In addition, the results are expected to serve as a scientific reference and to improve public understanding of Moraceae diversity.

Abstract

Groupers (family Serranidae) are high-value reef fish that are often prone to misidentification due to their morphological similarities. This research examined the phylogenetic relationships of grouper species landed at the Pondok Sampan Fish Landing Site in Labuhan Lombok using the Cytochrome Oxidase Subunit I (CO1) gene. One specific sample (K5) was analyzed to verify its taxonomic status. DNA isolation was performed through the CTAB technique, followed by PCR amplification and sequencing. Morphological identification initially suggested the sample belonged to the genus Epinephelus. However, molecular results showed that K5 is Aethaloperca rogaa (100% similarity). The phylogenetic analysis was conducted using the Neighbor-Joining approach with 10,000 bootstrap iterations and the Kimura 2-Parameter model in MEGA XI, which placed the specimen within a monophyletic group alongside A. rogaa sequences from Egypt, showing a genetic distance of 0.00. The nucleotide composition (T: 29.8%, C: 27.3%, A: 25.5%, G: 17.4%) was identical to the reference sequence, confirming the anti-G bias typical of teleost mitochondrial DNA. This research illustrates the critical importance of DNA barcoding to correct morphology-based misclassifications. It emphasizes the need for genetic confirmation in fisheries diversity evaluations and in the sustainable management of grouper populations across the Indo-Pacific.

Abstract

The utilization of pineapple peel waste as a fermentation substrate has the potential to increase product value while reducing environmental pollution. One product that can be developed from this waste is nata de pina. This study aimed to analyze the effects of Acetobacter xylinum starter concentration and fermentation time on the quality of nata de pina. The research employed a quantitative experimental method using a Completely Randomized Design (CRD) with three replications. The treatments consisted of starter concentrations of 10%, 15%, and 20%, and fermentation periods of 8, 10, and 12 days. The observed parameters included nata thickness, yield, color, and texture. Data were analyzed using Two-Way ANOVA, and Tukey's post hoc test at a 5% significance level. The results showed that starter concentration and fermentation time significantly affect the thickness and yield of nata de pina with the results showing a significant effect (p < 0.05). The highest thickness (0.78 mm) and yield (48%) were obtained at a 20% starter concentration with 12 days of fermentation. The best color and texture were produced by nata de pina fermented with a 20% starter concentration for 10 days. Furthermore, The results showed no significant interaction between starter concentration and fermentation time on nata thickness (p > 0.05), whereas a significant interaction was observed for nata yield (p < 0.05). In conclusion, increasing the concentration of A. xylinum starter and extending fermentation time improved the physical quality of nata de pina, while the combination of a 20% starter concentration and 10 days of fermentation produced the best characteristics. These findings demonstrate the potential of pineapple peel waste as a sustainable raw material for producing value-added functional food.

Abstract

Pelaksanaan kegiatan pengabdian kepada masyarakat telah berlangsung mulai Bulan April sampai dengan Agustus 2026. Mitra kegiatan adalah masyarakat tani Dusun Bunsambang Desa Sukarara Kabupaten Lombok tengah yang berprofesi sebagai petani dan peternak. Tujuan Kegiatan pengabdian kepada masyarakat ini adalah untuk mengedukasi mitra tentang pemanfataan kotoran ternak sebagai bahan baku pembuatan kompos serta cara pengunaannya pada lahan pertanian tanaman tomat. Budidaya tanaman tomat dilakukan pada lahan dengan luas 100 m2. Tanaman tomat hanya dipupuk menggunkan kompos tanpa adanya penggunaan pupuk anorganik. Kegiatan pengabdian kepada masyarakat dilakukan dengan metode ceramah dan pendampingan. Hasil dari pelaksanaan pengabdian adalah mitra memiliki keterampilan tentang pemanfaatan sampah organik dalam pembuatan kompos serta cara pengaplikasiannya dalam budidaya tanaman tomat. Tanaman tomat yang dibudidayakan oleh mitra tumbuh dan berproduksi dengan baik. Masyarakat yang menjadi mitra kegiatan, terlibat secara aktif pada semua tahapan kegianatan, mulai dari kegitan sosialisasi sampai dengan panen tanaman tomat.
