Abstract

This research was conducted from 15 March to 15 April 2021Brackishwater Fish Seed center (BBIAP) Kab. Meranti Islands, Riau Province. The stocking density and diameter of the PVC hole had a significant effect onthe growth of the Star Pomfret Fish (Tracinotus blochii). The small diameter ofthe PVC hole will produce air bubbles that burst faster than the diameter of themedium and large PVC hole. In this study, the highest number of bubbles wasproduced in treatment D1 (Ø 2 mm), and the best treatment and the effect onabsolute weight growth of this star pomfret fish was treatment D2 (Ø 3 mm),which was 2,3200 grams. This treatment has an impact on the agile movementand response of the fish to get the food given is very good, as well as the effectof low and high levels of dissolved oxygen resulting from differences in thediameter of the PVC holes. Star Pomfret Fish maintenance can be carried out with a high stockingdensity of up to 500 fish/m3. Where with a diameter of 3 mm PVC hole is ableto provide an absolute weight growth rate of 2,3200 grams, feed efficiency of64.4400%, specific growth rate of 6.0617% and survival rate of 97.51%.

Abstract

This research was conducted from December2015 until January 2016 at Technology Research and Development Center in Riau Balitbang.Thepurpose of this research was to investigate growth and survival rate of african catfish with addition bacterial dose in bioflocs techniques. This research using experimental method and completely random design (RAL) with three treatment and two replications, fourare P1 : 10 mL/m3 bacterial dose, P2 : 15 mL/m3bacterial dose, P3 : 20mL/m3bacterial dose. The result showed that african catfish with addition bacterial dose in bioflocs techniques affect significantly on the growth of absolute weight,the specific growth,but does not affect absolute length growth and survival rate. The best treatment were obtained in treatment P2 with 15mL/m3 bacterial dose, with value growth of absolute weight 50,15g, growth in absolute length 13,97cm, specific growth rate 3,39% and survival rate 98,16 %.   Keyword : african catfish, Dose bacteria, Bioflocs technology

Abstract

Stunting adalah sebuah kondisi gagal tumbuh kembang pada anak balita dibawah usia lima tahun dikarenakan asupan gizi yang kurang baik sehingga menyebabkan tinggi badan pada ukuran balita tersebut terlalu pendek untuk usiannya. Keikutsertaan mahasiswa dalam upaya percepatan pencegahan dan penanggulangan stunting dengan melakukan sosialisasi terhadap masyarakat merupakan hal sesuatu hal yang sangat penting. Pengetahuan dengan cara bersosialisasi akan berpengaruh dalam waktu jangka panjang. Kegiatan ini bertujuan sebagai edukasi terhadap masyarakat betapa pentingnya pencegahan stunting. Metode yang diguakan dalam penelitian ini yaitu tahap perencanaan meliputi studi pendahuluan dan perizinan. Tahap pelaksanaan meliputi sosialisasi kepada masyarakat. Hasil dari kegiatan adalah bertambahnya pengetahuan masyarakat akan bahaya stunting. Setelah dilakukan sosialisasi stunting, masyarakat antusias dalam materi yang disampaikan dibuktikan dengan hasil kuisioner masyarakat dari Kelurahan Lubuk Tukko Baru.

Abstract

This study investigates the effectiveness of combining the low-tide transect method with the use of crab pots to map the spatial distribution of mangrove crabs (Scylla spp.) in the Kalangan River, Central Tapanuli. Mangrove crabs are ecologically and economically significant species in coastal environments, yet limited data exist on their spatial population dynamics. An exploratory survey was conducted over a period of one month across three transect sites using standardised 1×1 meter PVC frames and systematically placed crab pots. Observations included species composition, carapace size, and habitat substrate type. The findings revealed that Scylla olivacea dominated the catch (68%), with the highest density recorded at transect 2 (0.86 individuals/m2), characterised by fine, sandy-muddy substrate and moderate mangrove cover. Transect 1 showed the lowest density (0.63 individuals/m²), likely due to degraded mangrove vegetation and coarse sandy substrate. A positive correlation was observed between tidal depth and catch abundance. The results suggest that this integrated method offers a reliable baseline for assessing mangrove crab populations and can inform sustainable coastal resource management practices.

Abstract

This study aims to evaluate the effectiveness of an innovative filtration system in bucket aquaponics “budikdamber” on the growth performance of water spinach (Ipomoea reptans) at three different locations: Tapian Nauli, STPK Matauli, and the Central Bureau of Statistics of Central Tapanuli (BPS). The experimental design was a randomized block design with two treatments (conventional and innovative filtration systems) and three replications. Observed parameters included plant height, number of leaves, and daily growth rate. The results showed that using the innovative filtration system significantly enhanced plant growth compared to the conventional system. The innovative system recorded the highest plant height at Tapian Nauli, reaching 26.3±1.7 cm and 11.5±0.9 leaves per plant, with a daily growth rate of 3.62%. The innovative filtration system improved water quality through mechanical and biological filters that supported the conversion of ammonia into plant-available nitrate. Thus, this system can be an adaptive and sustainable technology to enhance budikdamber productivity, particularly in coastal and rural areas.

Abstract

Mangrove crab (Scylla spp.) aquaculture has high economic potential, but its implementation in coastal areas such as Central Tapanuli Regency still faces challenges, including limited land, water quality fluctuations, and maintenance efficiency. This study aims to develop and test the effectiveness of the Crab Flow System (CFS), a modular crab culture system based on controlled water flow designed to improve crab growth and survival performance. The research was conducted from January to March 2025 at the Laboratory of the Matauli College of Fisheries and Marine Sciences, North Sumatra, using an experimental method with two treatments: (1) conventional culture and (2) culture using CFS, each with three replicates. Parameters observed included daily growth rate (SGR), survival, and water quality (temperature, pH, DO, ammonia). Results showed that the use of CFS resulted in 18.4% higher average daily growth and 92% survival rate, compared to the conventional system. Water quality in the CFS system was also more stable and within the optimal range for crab growth. In conclusion, the CFS system proved to be effective in increasing the efficiency and productivity of crab culture, and has the potential to be an innovative solution for the development of sustainable aquaculture in coastal areas.
