Abstract

Acanthopsoides molobrion is a freshwater previously known to be spread across Malaysia and Borneo. This study aimed to record for the first time the occurrence of the A. molobrion in Bangka Island, Indonesia, and update the geographic distribution of this species. This new record of freshwater fish provides an important contribution to the comprehension of the biogeography of the species. The purpose sampling approach was employed for this study to collect specimens. The species were then identified morphologically by the application of morphometric and meristic methods, and molecularly through the employ of DNA Barcoding. On 20th January 2023, two A. molobrion specimens were collected from the Bumang Kemuja River, Bangka Island using a fish trap. The new record of A. molobrion found here is the southernmost record for this species, expanding its geographic distribution. In addition, the latest record site is about 500 km south of the nearest locality in Peninsular Malaysia, and about 750 km southwest of the nearest locality in Borneo. The new record of A. molobrion has expanded the species' recorded distribution range, which has added to our understanding of this species. Furthermore, we present an updated record for the A. molobrion DNA sequence based on the COI gene. This sequence is the first DNA Barcode to Indonesia. Subsequently, the DNA sequence was registered into NCBI Genbank with the access code OR144414. This DNA barcode will be used as a standard for identifying A. molobrion and will aid in DNA and biotechnology-based studies in the future.

Abstract

Ikan lele (Clarias sp.) merupakan salah satu komoditas perikanan unggulan di Indonesia. Oleh karena itu banyak orang membudidayakan ikan lele, termasuk pembudidaya di Paguyuban Pembudidaya Lele (PPL) Tambak Wedi, Tambak Wedi, Surabaya. Dengan lokasi yang berada di kota Surabaya, keterbatasan air mendorong budidaya lele untuk dilakukan secara urban aquaculture. Akan tetapi, serangan patogen menjadi kendala di (PPL) Tambak Wedi. Serangan patogen menyebabkan kerugian bagi pembudidaya ikan lele di Tambak Wedi. Hal tersebut menyebabkan omset pembudidaya menurun dan harus menutup kolam akuaponik. Salah satu solusi yang dapat dilakukan adalah pemberian bioflok. Bioflok memiliki 3 fungsi utama yaitu meningkatkan kualitas air, sebagai bahan tambahan pakan organisme budidaya dan menekan patogen. Pelaksanaan kegiatan ini terdiri dari tiga tahap yaitu : (1) tahap pembuatan kolam percobaan dan petakan pemeliharaan ikan lele, (2) tahap penyuluhan dan peragaan dan (3) tahap penerapan bioflok pada budidaya ikan lele. Dari kegiatan ini didapatkan hasil bahwa sebelumnya para pembudidaya di Paguyuban Budidaya lele Tambak Wedi Kota Surabaya, Jawa Timur, sudah penah mengaplikasikan bioflok namun mengalami kendala sehingga tidak diteruskan lagi. Setelah kegiatan pengabdian ini, para pembudidaya tergerak untuk kembali mengaplikasikan bioflok untuk usaha budidaya mereka.

Abstract

The purpose of this study was to investigate the water quality and phytoplankton abundance in Lake Toba to determine its trophic status. This research was conducted from January to March 2024 at four stations in Lake Toba. Water samples were taken using a UWITEC water sampler and a plankton net and brought to the laboratory for analysis. The study measured physical and chemical water quality and phytoplankton abundance. The results showed a brightness ranging between 5.8 and 6.3 meters, chlorophyll-a content <10 µg/L, total nitrogen <750 µg/L, and phosphorus ranging from 20 µg/L to 30 µg/L. Based on these parameters, the nutrient quality of Lake Toba was classified as mesotrophic. Phytoplankton abundance ranged from 22,514 to 33,475 individuals/L, with 33 genera identified across nine classes: Bacillariophyceae, Chlorophyceae, Cyanophyceae, Coscinodiscophyceae, Dinophyceae, Euglenida, Fragilariophyceae, Mediophyceae, and Zygnemophyceae. The diversity index (H') was 2.631 - 2.723, the uniformity index (E) was 0.828 - 0.872, and the percentage of blue-green algae was 14.75 - 20.85. Zygnemophyceae was the most dominant phytoplankton class, with Staurastrum sp. being the most prevalent species. In conclusion, Lake Toba's waters are categorized as mesotrophic based on the chemical parameters and as eutrophic based on phytoplankton abundance, indicating potential nutrient enrichment issues that warrant further investigation.

Abstract

The limited knowledge and skills in the hatchery technology application of the freshwater fish to seed production business are obstacles faced by prospective young entrepreneurs in the aquaculture sector. The Community Partnership Program (PKM) was provided as a strategic step to overcome the obstacles faced by the target partner group in this PKM activity in line with the Public Vocational Secondary School's (SMKN) expectations to provide sufficient insight into science and technology for SMKN students as provision for independent entrepreneurship. The aim of this PKM was to transfer the application of freshwater fish (catfish) hatchery technology and the produce fish seeds independently. The activity method was conducted through: a) delivery of material and training related to broodstocks selection and gonad maturation, b) training on the application of freshwater fish hatchery technology (catfish), and c) regular monitoring and assistance to PKM target partner groups by involving related agencies (SMKN). Delivery of material was carried out regularly, both online and face to face (offline). Approximately 40 students of SMKN Ngadirojo, Pacitan Regency who took the flagship program of Aquaculture Agribusiness, attended this activity. This PKM activity was also attended by accompanying teachers. The practical results show an increase in the knowledge and skills of partners in catfish hatchery through the application of semi-artificial catfish broodstocks spawning technology.

Abstract

Graphical Abstract Highlight Research Tuban (Indonesia) aquaculture commodities are surveyed. Aquaculture diversity in Tuban are consisted of 5 fields, namely rice field ponds, floating net cages, freshwater ponds, and brackish aquaculture ponds Aquaculture commodities in Tuban consist of 11 families and 14 species of the main aquatic production. Cyprinus carpio or common carp is one of the commodities cultivated in four different aquacultures. Abstract Fishery is a sector expected to overcome the food crisis. Indonesia is one of the leading countries in high volumes of fishery production in most of its areas, including the Regency of Tuban in East Java Province. The area of Tuban Regency is 1,839.94 km2 with the coastline covers 65 km and a sea area of 22,608 km2. This study aims to provide information regarding aquaculture production, diversity, and distribution in Tuban.  This study used a survey method in collecting fishery commodity data directly from aquaculture areas. The results of this study showed that the highest production came from the brackish water with a value of 32.46% (13,561.79 tons), followed by rice field pond (27.79% or 11,612.45 tons), freshwater pond (25.76% or 10,764.62 tons), floating net cage (13.97% or 5,836.59 tons), and marine (0.1% or 5.67 tons). Aquaculture biodiversity in Tuban consisted of 11 families and 14 species of the main aquatic produces, such as Cyprinidae (Cyprinus carpio, Barbonymus gonionotus, Parastromateus niger), Clariidae (Clarias bathracus), Pangasiidae (Pangasianodon hypophthalmus), Penaeidae (Penaeus monodon, Litopenaeus vannamei), Channidae (Channa striata), Cichlidae (Oreochromis niloticus, Oreochromis mosammbicus), Osphronemidae (Osphronemus gourami), Serranidae (Epinephelus), Lutjanidae (Lutjanus), and Chanidae (Chanos chanos). Cyprinus carpio or common carp is fish cultivated in four different aquacultures, namely rice field pond, floating net cages, freshwater ponds, and brackish aquaculture ponds. Unfortunately, the diversity and production of marine aquaculture has not been improved even though Tuban has large marine areas.

Abstract

This research investigates the phytochemical composition, antioxidant activity, and antibacterial efficacy of Ipomoea pes-caprae extracts collected from Pantai Talang Siring Pamekasan, Madura. Phytochemical analysis revealed the presence of alkaloids, flavonoids, phenolic compounds, terpenoids, tannins, and saponins in the extracts, indicating their rich bioactive profile. Antioxidant activity assessed via the DPPH assay demonstrated concentration-dependent scavenging of free radicals, with methanol and ethanol extracts exhibiting superior activity compared to the aqueous extract. Antibacterial assays against Escherichia coli and Staphylococcus aureus revealed significant inhibitory effects, with methanol and ethanol extracts displaying greater potency than the aqueous extract. These findings underscore the potential of Ipomoea pes-caprae as a source of natural antioxidants and antimicrobial agents, warranting further investigation into its pharmacological applications and therapeutic potential.
