Abstract

Ulva lactuca, a widely available green seaweed, has demonstrated promising bioactivity as a tyrosinase inhibitor. This study aimed to evaluate the tyrosinase inhibitory activity of U. lactuca extracts and identify the active compounds responsible. The seaweed was extracted using methanol via maceration, followed by partitioning with hexane, chloroform, and water. Total phenolic and flavonoid contents were determined using UV-VIS spectrophotometry, and tyrosinase inhibition was assessed in vitro. Among the tested fractions, the hexane fraction exhibited the highest tyrosinase inhibitory activity with an IC50 value of 584.34 ± 35.07 µg/mL, classifying it as an active inhibitor. Although this activity was weaker than kojic acid (IC50 = 11.07 ± 0.86 µg/mL), the hexane fraction showed relatively high phenolic (11.66 ± 0.53 mg GAE/g) and flavonoid (9.75 ± 0.30 mg QE/g) contents. Gas Chromatography-Mass Spectrometry (GC-MS) analysis identified several bioactive compounds, notably 2,4-dimethoxycinnamic acid, chalcone, and derivatives such as 2,6-dihydroxybenzoic acid and phloretin. These findings highlight the potential of U. lactuca, particularly its hexane fraction, as a source of natural tyrosinase inhibitors. This opens avenues for its application in the pharmaceutical and cosmetic industries, especially in formulations targeting hyperpigmentation and skin brightening.

Abstract

The potential for aquaculture in Aceh Province is enormous, one of which is in the Nagan Raya Regency area. Fish farmers in the Nagan Raya Regency area have long cultivated freshwater catfish using a conventional system. This catfish cultivation system does not increase the production of farmed fish and does not produce organic fish. This activity aims to educate and assist in applying turmeric probiotic supplementation technology to increase farmed fish production and produce organic catfish. The implementation of this activity is carried out using education and assistance. The stages of implementing the activity include initial discussion with farmer partners (UPR Clarias Fish Farm), program preparation, education of community service activities, community service activity workshops, monitoring and evaluation, and activity reporting. Indicator of success in the education and assistance method is that partners understand the material and practices presented by the presenter regarding turmeric probiotic supplementation and good fish farming methods. This activity is evaluated through pre-test and post-test questionnaires using the material provided. This community service activity is said to be successful if the average value of the farmer partners is obtained ≥75% of the post-test questionnaire given. The results of this community service activity are in the form of increased knowledge and understanding of farmer partners. The harvest results also showed an increase in mass production of farmed fish given turmeric probiotics compared to farmed fish without turmeric probiotics. In conclusion, UPR Clarias Fish Farm's fish farming partners experienced an 80% increase in understanding of turmeric probiotic supplementation and catfish production using turmeric probiotics increased the length gain by 3.9 cm longer or 17.89% compared to without probiotics and fish given turmeric probiotics were also 25.96 grams heavier or 21.72% heavier than without probiotics.

Abstract

This research aims to analyze the supply chain and marketing chain of freshwater fish in the West-Southern Region of Aceh Province, Indonesia. The research activities took place from May to July 2022, with data collection continuing in 2023. The determination of data collection locations used purposive methods, and data collection was conducted through survey methods. Data were obtained from fish traders in four  markets: Ujong Baroh Meulaboh Fish Market, Blang Pidie Market, Nagan Raya Market, and Krueng Sabe Fish Market. Data analysis was conducted descriptively. The research results indicate that the supply chain includes fish farmers, partner traders, collector traders, retailers, and consumers, and there are two supply chains based on regions: inter-insular and intra-region. The dominant types of freshwater fish supply are catfish and tilapia. Tilapia has a higher price compared to catfish. Tilapia is dominant in the Ujong Baroh market, while catfish is dominant in the Blang Pidie  market. It has become a substitute when sea fish are scarce or expensive in the market. Based on the value chain analysis, a margin ranging from 10% to 30% was obtained. Partner traders play a significant role in production activities and the supply chain due to cooperation in input-output factors. Challenges in the freshwater fish supply consist of seeds and feed, with seeds mostly supplied from outside West-South, accounting for more than 80%.. Addressing freshwater fish supply challenges in Southwest Aceh requires an integrated supply chain approach enhancing hatchery systems and fry distribution upstream, improving aquaculture infrastructure and feed subsidies at the production level, and establishing collection centers, cold storage, and modern markets in key districts to strengthen distribution, stabilize prices, and improve food security.

Abstract

Program Kuliah Kerja Nyata (KKN) yang dilaksanakan di Desa Suka Jaya, Kecamatan Kuala Baru, Kabupaten Aceh Singkil, berfokus pada pemanfaatan potensi perikanan lokal, khususnya ikan tongkol, untuk dijadikan produk abon ikan. Inisiatif ini bertujuan untuk meningkatkan minat  masyarakat  dalam  berwirausaha  serta  mengoptimalkan  hasil  tangkapan  ikan  yang selama ini belum dieksploitasi secara maksimal. Metode yang digunakan melibatkan pelatihan pembuatan abon ikan, mulai dari persiapan bahan hingga pengemasan produk. Hasil kegiatan menunjukkan bahwa abon ikan yang dihasilkan memiliki kualitas baik dari segi rasa, tekstur, dan daya tahan. Selain itu, program ini berhasil meningkatkan keterampilan masyarakat setempat, terutama ibu rumah tangga, serta membuka peluang usaha baru yang berdampak positif pada perekonomian desa. Tantangan yang dihadapi meliputi keterbatasan teknologi pengolahan dan akses pasar yang masih terbatas. Oleh karena itu, diperlukan dukungan lebih lanjut dalam bentuk pelatihan lanjutan dan pemasaran yang lebih luas untuk memaksimalkan potensi produk abon ikan ini.
