Abstract

Mangroves have two meanings, the first refers to plant communities or forests that are able to tolerate salinity or saltwater conditions (aquifers). While the second refers to individual plant species, mangrove species inventories are also important in a global context, given the role these ecosystems play in storing carbon and protecting coasts from storms and erosion. This study aims to inventory of mangrove species in Nagari Pilubang, Sungai Limau District, Sungai Limau Regency, West Sumatra. This study used the Spot Check method. The results of the inventory of mangrove species at the observation location showed that there were 17 species from 16 families that make up the mangrove forest observed. True mangroves include Sonneratia caseolaris, Nypa fruticans, Acrostichum aureum, Acanthus ebracteatus, Acanthus ilicifolius, while the following mangroves include Hibiscus tiliaceus, Derris trifolia, Dolichandrone spathacea, Pandanus tectorius, Cerbera manghas, Melastoma candidum, Ardisia elliptica, Glochidion littorale, Barringtonia asiatica, Calophyllum inophyllum, Morinda citrifolia, and Wedelia biflora.

Abstract

Mangrove forests are very important coastal ecosystems worldwide as they provide a wide range of ecological, economic, and social benefits. One of the key components of mangrove forest ecosystems is mangrove litter, which consists of leaves, twigs, and small organisms that fall from mangrove trees. This litter is a food source for decomposing organisms, such as crabs and mollusks, and contributes to the nutrient cycle of the mangrove ecosystem after going through the decomposition rate process. This study aims to determine the decomposition rate of mangrove litter in Nagari Pilubang, Sungai Limau District, Padang Pariaman Regency. This research was conducted in September 2023-January 2023. This research method uses a litter bag to store leaf litter for 30 days and collection is done every 10 days with 3 collections and then the rate of decomposition is calculated. The results showed that on the last day the decomposition rate at station 3 was 0.365% which was higher than stations 1 and 2 which were only 0.418% and 0.412% respectively.

Abstract

The community of Sikabaluan Village primarily earns a living as fishermen. The obstacles in selling fishermen's products are related to the geographical location of Sikabaluan village, which has limited transportation between the village and areas outside the island. The issues found in the village of Sikabaluan are 1) The accumulation of fish during the harvest season, causing fish prices to tend to be lower than usual, even resulting in unsold fish that spoil, and 2) A lack of knowledge among the community regarding fish preservation. This relates to how to preserve fish so that it does not spoil quickly and has a longer shelf life, as well as how to utilize and prepare natural materials as natural preservatives. 3) There is a lack of skills among the community to process fishery products into other types of food, so that unsold fish can be transformed into other food types with higher market value. Therefore, it is necessary to provide assistance to the community of Sikabaluan village to enhance their knowledge regarding fish preservation and how to process fish into other types of food with high economic value. The method used in this service involves counseling and training for the community. This activity will be held in August 2024 and will be attended by 20 participants from the fishing community of Muara Sikabaluan village. The results of this activity show that (1) there is an increase in public knowledge about food and nutrition as well as innovations in fish processing. (2) The community has acquired skills in processing fish products into nuggets. (3) This knowledge and skill can serve as a foundation for businesses to meet the community's livelihood needs, thereby enhancing the economic situation of the community

Abstract

Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis tumbuhan bawah yang ditemukan pada habitat yang diduga sebagai tempat hidup Nesolagus netscheri di Gunung Singgalang dan Tandikat, Sumatera Barat. Metode eksplorasi digunakan untuk menginventarisasi tumbuhan bawah di dua stasiun penelitian yang terletak di jalur pendakian kawasan Taman Wisata Alam (TWA) Gunung Singgalang dan Tandikat, pada ketinggian antara 600-1.900 m. Identifikasi jenis dilakukan dengan bantuan aplikasi identifikasi tumbuhan dan pencatatan lokasi dengan menggunakan GPS. Hasil penelitian menunjukkan bahwa terdapat 24 famili dengan total 49 spesies tumbuhan bawah yang teridentifikasi. Famili dengan jumlah spesies terbanyak adalah Gesneriaceae (7 spesies), diikuti oleh Rubiaceae (6 spesies) dan Araliaceae (5 spesies). Perbedaan komposisi jenis di kedua lokasi tersebut dipengaruhi oleh faktor lingkungan seperti aktivitas vulkanik, topografi, pH tanah dan kelembaban udara. Beberapa spesies dari famili Gesneriaceae, seperti Crantzia cristata, Kohleria spicata, dan Cyrtandra paludosa, memiliki potensi sebagai sumber pakan N. netscheri di alam. Penelitian ini memberikan wawasan tentang keanekaragaman tumbuhan bawah dan potensi vegetasi sebagai pakan satwa endemik langka, sehingga dapat menjadi dasar dalam upaya konservasi spesies N. netscheri dan ekosistem hutan pegunungan Sumatera

Abstract

The cere fish species (Gambusia affinis) is a small fish, which is 2-3 cm. This fish is a wild fish that fills rivers, ditches and ditches. Cere fish are generally easy to adapt and reproduce. However, the water that irrigates rivers, ditches and ditches often contains community wastes, whether in the form of household waste, laundry, or even oil waste from workshops. So this study aims to obtain the LC5o-72 hour value of waste originating from river waste, laundry, and workshop oil on cere fish mortality. This research was conducted using a completely randomized design experiment. Each waste was treated in 4 treatments with different doses, namely 5 ml/L, 10 ml/L, 25 ml/L, and 50 ml/L for 72 hours with checking every 3 hours, 24 hours, 48 hours, and 72 hours. The results showed that laundry waste had a tolerance limit at a concentration of 10 ml/L and waste oil at a concentration of 25 ml/L.

Abstract

Tomato (Solanum lycopersicum L.) is one of the horticultural commodities with high economic value whose growth is greatly influenced by environmental conditions. This study aims to examine the phenology of tomato plants, including the time of flowering and flowering duration in different environmental conditions as a basis for developing more effective cultivation techniques. The study was conducted in two locations, namely Kamang Magek District and Padang City, with 20 replications per location. Phenology observations were carried out on the time of flowering and flowering duration of tomato plants, and the data obtained were analyzed using the t-test at a significance level of 5%. The results showed a significant difference between the two locations, where the average time of flowering in Kamang Magek District was 38.5 days after planting (DAP) with a flowering duration of 10.85 days, while in Padang City the time of flowering occurred at 75.8 DAP with a flowering duration of 30.3 days. This difference indicates that environmental conditions in Kamang Magek District are more supportive of accelerating the flowering phase with a shorter flowering cycle.

Abstract

Setiap hari aktivitas masyarakat termasuk masyarakat kampus (dosen, pegawai, dan mahasiswa) selalu menghasilkan limbah organik dan anorganik. Limbah dapat berasal dari sisa makanan sivitas akademika UNP maupun sisa bahan praktikum-praktikum di laboratorium biologi dan kimia FMIPA UNP. Ketika lingkungan kotor maka tidak sedikit tim cleaning service di UNP yang kewalahan. Tujuan kegiatan ini adalah bagaimana pengolahan sisa sayur dan buah di lingkungan kampus menjadi produk bermanfaat. Solusi yang ditawarkan melalui pengabdian ini adalah mengolah sampah makanan khususnya buah dan sayuran menjadi larutan ecoenzyme yang dapat digunakan untuk berbagai keperluan bagi kesehatan dan lingkungan. Oleh karena itu sangatlah tepat jika hadirnya suatu pusat produksi ecoenzyme di jurusan biologi FMIPA UNP. ECOBY adalah merek dagang ecoenzyme yang dibuat oleh unit usaha PPUPIK Jurusan Biologi FMIPA UNP berkerjasama dengan Tim Mahasiswa HMJ Biologi. Proses pembuatan ecoenzyme berasal dari sampah sayur dan kulit buah, gula merah dan air dengan perbandingan 3:1:10. Proses ini membutuhkan waktu 90-100 hari minimal. Sisa buah yang digunakan adalah kulit apel, jeruk, nanas, pir, semangka, lemon, melon, mangga, alpukat yang diperoleh dari lingkungan sekitar UNP. Ecoenzyme mempercepat reaksi biokimia di alam untuk menghasilkan enzim yang berguna untuk berbagai kebutuhan sehari-hari.
