Abstract

Sea cucumbers are members of the Phylum Echinodermata which have high economic value and widely used by the coastal communities of the Riau Islands as food sources and medicines. Unregulated fishing greatly pressure sea cucumber populations in natural waters. Aquculture is regarded as a solution to the over-exploitation of sea cucumbers from natural waters. However, further research is needed to establish the better technical and economic efficiency. Local sea cucumber farmer needs information about the technical aspects of sea cucumber seed production so they can produce the seeds independently. Therefore, a series of dissemination and demonstrations were organized to introduce the method of produce sea cucumber seeds using the fission technique. This community service activity was carried out using the participatory action research (PAR) method involving the Maju Mandiri fish farmer group in Kampung Madong, Kampung Bugis Village, Tanjungpinang City. The team carried out counseling and demonstrated the binding procedure to simulate fission in sea cucumber. Our partner group seemed enthusiastic about participating in the activity and quite proficient on some basic fission techniques to provide sea cucumber seeds. This activity also raises awareness among the locals to actively maintain the sustainability of marine resources. So, we hope our partner group can start the sea cucumber culture business with independent seed production, and they can achieve our goals to improving community welfare and preserving the water environment simultaneously.

Abstract

Ikan badut Premnas biaculeatus hasil biakan atau budidaya cenderung mengalami degeneratif warna atau memiliki warna tubuh yang pudar tidak seperti habitat alami. Penelitian ini bertujuan untuk meningkatkan kecerahan warna ikan badut melalui penambahan tepung buah yang mengandung ?-karoten pada pakan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) 4  perlakuan 5 ulangan. Pemberian pakan ikan badut dengan Kontrol (tanpa penambahan tepung), perlakuan A (tepung labu kuning) B (tepung wortel) dan C (tepung ubi jalar ungu) dengan dosis masing-masing 15% (15g/100g pakan). Ikan yang digunakan berukuran panjang dan berat masing-masing  ± 3 cm dan ± 0,5 g. Padat tebar 1 ekor/soliter dan jumlah ikan 20 ekor. Parameter perubahan warna badan merah menunjukkan hasil yang terbaik pada perlakuan B (tepung wortel 15%) dengan nilai R (-14,1± 4,1), G (-16,1±3,8) dan B (-9,3± 5,8). Parameter perubahan warna badan putih diperoleh perlakuan terbaik pada kontrol (tanpa penambahan tepung) dengan nilai R (28,3±0,8), G (34,5±3,1) dan B (28,5±1,0). Parameter laju pertumbuhan bobot mutlak dan panjang mutlak terbaik terdapat pada perlakuan B (tepung wortel 15%) dengan nilai berturut-turut adalah (0,324±0,01) dan (0,64±0,05). Parameter tingkat kelangsungan hidup mendapatkan nilai (100±0,00).

Abstract

Seaweed or algae is macro algae whose habitat is in sea water and several types in brackish water. There are several seaweed cultivation techniques, one of which is the off-bottom technique. The off-bottom technique with different levels of cultivation facilities where seaweed seeds are placed has never been carried out by aquaculturis in the Bintan Island area, Riau Islands (Kepri). The aim of the research was to determine the speed of increase in weight of seaweed grown in cultivation facilities with different numbers of levels using the off-bottom technique. The research will be carried out in September-October 2022 on the sea coast of Tembeling Village, Bintan Regency. The experiment was carried out with three treatments and each was repeated 3 times in a completely randomized design. The treatments consisted of 1 level (K), 2 levels (A) and 3 levels (B) cultivation facilities. The Anova results showed that the weight gain of the seaweed test was significantly different between the three treatments (p<0.05). The best results in the 3 level cultivation facility treatment (B) were 11.04±0.73 g, but the survival and daily growth rates were not significantly different (p>0.05).

Abstract

Grouper fish farming in Indonesia has great potential, but water quality management remains a challenge. Manual monitoring at hatchery D-Marine aquaculture struggles to detect sudden changes, risking mass mortality. This study developed an IoT-based water quality monitoring system using an ESP32 microcontroller, DS18B20 temperature sensors, pH sensors, dissolved oxygen (DO) sensors, a micro-SD card, an organic light emitting diode (OLED) display, and the Ubidots platform. The methodology involved device design, sensor calibration, and field testing. Calibration showed sensor accuracy above 90%. Field tests recorded water temperatures of 26.84 °C (tank 1) and 27.74 °C (tank 2), with pH values of 6.73 and 6.87, which did not meet Indonesian national standard (SNI) standards. Data transmission to Ubidots had a 95% packet delivery ratio (PDR) for device 1 and 97% for device 2. The system successfully provided real-time water quality data, supporting effective farm management. However, improvements to the dissolved oxygen sensor and an automatic control system are needed for better stability and efficiency.
