Abstract

Pelatihan penggunaan kolam bundar HDPE (High-Density Polyethylene) untuk budidaya ikan nila memberikan solusi efisien, hemat biaya, dan ramah lingkungan. Kegiatan ini dilakukan sebagai bagian dari pengabdian masyarakat di Desa Batuyang, Lombok Timur, dengan melibatkan kelompok pembudidaya ikan “Sinar Timur”, akademisi, mahasiswa, dan masyarakat. Budidaya ikan nila sebelumnya menggunakan kolam terpal yang mudah bocor atau kolam semen yang mahal. Oleh karena itu, kolam bundar HDPE dipilih sebagai alternatif inovatif. Pelatihan dilaksanakan di lahan milik pembudidaya setempat, menggunakan metode kombinasi teori dan praktik. Peserta diajarkan langkah-langkah konstruksi kolam, mulai dari pengukuran, pengelasan lembaran HDPE, persiapan lokasi, pembentukan struktur dasar, pemasangan besi wermes, hingga uji coba dan penyesuaian akhir. Kolam HDPE yang dibuat memiliki diameter 5 meter, dilengkapi sistem aerasi menggunakan blower, dan dirancang untuk tahan cuaca ekstrem serta keausan. Kegiatan diawali dengan persiapan dan knowledge transfer dari tim pengabdian, yang juga menyediakan sarana dan prasarana. Hasilnya, kelompok pembudidaya berhasil membuat kolam HDPE yang kokoh, tahan lama, dan praktis untuk budidaya ikan nila. Perawatan rutin tetap diperlukan untuk menjaga performa kolam agar dapat digunakan dalam jangka panjang. Solusi ini diharapkan mendukung keberlanjutan budidaya perikanan di wilayah tersebut.

Abstract

The objective of this research was to determine the decline in freshness of skipjack tuna stored at room temperature. Fish freshness testing was carried out using organoleptic tests such as eyes, gills, odor and texture of the fish, as well as counting the number of bacteria taken from the gills of skipjack tuna. Skipjack tuna was taken from 3 different markets in Mataram City. Observations on the fish were carried out twice, the first in the morning after the fish was taken from the market at 09.00 WITA and the second observation at 15.00 WITA. The results of the study showed that in the morning the skipjack tuna was in a condition of declining quality freshness, then during the day the quality of the skipjack tuna decreased further with a condition that was almost rotten. The results of observations of total bacteria also showed that in the morning the total bacteria had passed the predetermined threshold and during the day the number of bacteria increased until it could not be counted.

Abstract

The transgenic GloFish Tetra (Gymnocorymbus ternetzi), engineered to express fluorescent proteins, is increasingly popular in the global ornamental aquaculture industry. However, optimized protocols for its breeding and larval rearing under tropical freshwater conditions remain underexplored. This study aimed to evaluate the effects of substrate type and larval stocking density on reproductive performance, larval survival, growth, feed utilization, and fluorescent color intensity in GloFish Tetra. A 3×3 factorial experiment was conducted at a tropical hatchery in Indonesia using three substrate types—no substrate (S0), artificial fiber mat (S1), and natural aquatic vegetation (Hydrilla verticillata, S2)—combined with three stocking densities: 15, 10, and 5 larvae per liter. Key parameters, including fecundity, fertilization rate, hatchability, survival rate (SR), specific growth rate (SGR), feed conversion ratio (FCR), and color intensity (∆E), were measured and statistically analyzed using a two-way ANOVA. Results demonstrated that the S2-D5 treatment (natural vegetation with low density) significantly improved fecundity (330.2 ± 10.8 eggs), hatchability (82.3 ± 2.7%), SGR (4.30 ± 0.11%/day), and color intensity (∆E = 17.6 ± 1.0), while achieving the lowest FCR (1.31 ± 0.07). In contrast, high-density and substrate-free conditions (S0-D15) yielded the poorest performance across all metrics. These findings underscore the crucial role of environmental enrichment and density management in enhancing both biological and aesthetic traits in GloFish Tetra. This study presents a validated protocol for enhancing hatchery success and improving the ornamental quality of transgenic fish in tropical aquaculture systems.

Abstract

Turtles are a species that faces the threat of extinction due to habitat degradation, hunting, and marine pollution. North Lombok Regency has a coastal ecosystem that is an important habitat for turtles to lay their eggs, so conservation efforts are crucial. This community service program aims to optimize the release of hatchlings by increasing community and tourist participation as an ecotourism-based conservation strategy. The methods used include conservation education, community involvement in beach patrols, and hatchling releases involving tourists with a local wisdom-based approach. The results of the activities show an increase in community and tourist awareness of the importance of turtle conservation, as evidenced by their increased involvement in nest monitoring and hatchling releases. In addition, this program contributes to local economic growth through conservation-based ecotourism, where communities are starting to get involved in tourism support services. However, there are still challenges in terms of long-term funding and regulations that need to be strengthened to maintain a balance between tourism and conservation activities. In conclusion, a hatchling release program involving communities and tourists can be an effective and sustainable conservation model. With the right strategy, such as increasing education, partnerships with various parties, and supporting regulations, this program can continue to grow and provide ecological and socio-economic benefits for the community in North Lombok Regency.
