Abstract

Freshwater pomfret (Colossoma macropomum) is one of the fishery commodities with high economic value. This encourages the supply of pomfret for consumption to increase, so that the supply of seeds for rearing is also increasing. The purpose of this study was to determine the growth and survival of pomfret fry. The test fish used were Freshwater Pomfret with an initial length of 3 -5 cm with an initial weight of 2.1 - 2.5 grams, which were kept in a 30 liter container. The research method used is an experimental method using a completely randomized design (CRD), consisting of 5 levels of treatment with 3 replications. The results showed that treatment A (stocking density 50 birds/25 liters) showed the highest growth of 4.01 grams, with a length of 5.67cm, survival of 96.67%, and FCR of 6.98 The lowest growth was in treatment P1 ( stocking density of 10 fish/25 liters) was 2.97 grams, with a length of 4.31 cm, survival of 96.67% and FCR of 1.45. The results of observations of water quality measured during the study were still within the tolerance limits for the growth and development of Freshwater Pomfret. From the results of the research conducted, it is known that the best stocking density for growth and survival in the maintenance of Freshwater Pomfret is P5 treatment (stocking density of 50 fish/25 liters) with an average absolute weight of 4.01 grams, a growth rate of 0.100 grams/day. absolute length 5.67 cm. 100% survival.

Abstract

The purpose of this study was to identify the diversity of fish species based on the waters in Kuala Langsa Village and provide outputs in the form of water conditions in Kuala Langsa Village. Fish sampling was carried out using the Purposive Sampling method. The composition of fish species caught at the three stations consisted of 12 species, namely: Mystus nemerus, Channa striata, Chanos chanos, Drepane punctate, Stolephorus sp, Gerres erythourus, Leiognathus splendens, Lutjanus johnii, Planiliza subviridis, Johnius belangerii, Epinephelus sp., Terapon jarbua. The total number of fish caught at station I was 36 fish, station II was 22 fish, and station III was 28 fish. Total relative abundance at stations I, II, and III in Kuala Langsa Kota waters obtained the highest abundance of fish from the species Leiognathus splendens with a value of 31.40% while the lowest relative abundance was found in the species Epinephelus sp and Chanos with a value of 1.16%. The diversity index at stations I, II, III ranged from 1.73 to 2.19. The three stations had moderate diversity criteria, indicating that the biological condition and fish diversity were still stable. Uniformity values of stations I, II, III, range from 1.53-1.59 which indicates high uniformity. This is due to the high uniformity because the fish population is spread evenly at each station. Dominance values at stations I, II, III range from 0.14-0.24 indicating low dominance or no fish species dominating at each station. Keywords: Diversity; Dominance; Kuala Langsa; Relative abundance; Uniformity

Abstract

Limbah tahu yang mengandung gizi yang tinggi sekitar 17,72% protein dan 66,24% karbohidrat sehingga berpotensi menjadi sumber energi. Gampong Lengkong, yang dikenal sebagai penghasil tahu terbaik di Kota Langsa, biasanya memproduksi tahu sebanyak 200–250 kg per hari. Namun, selama masa pandemi, produksi menurun drastis menjadi 100–150 kg per hari, yang berdampak negatif terhadap perekonomian lokal. Kegiatan pengabdian kepada masyarakat ini menawarkan solusi dengan melatih warga setempat, khususnya para produsen tahu dan anggota PKK, untuk mengolah limbah tahu menjadi keripik bernilai ekonomis. Kegiatan ini mencakup sesi ceramah untuk menambah wawasan peserta mengenai pemanfaatan alternatif limbah tahu, serta sesi praktik yang menunjukkan secara langsung proses pembuatan keripik limbah tahu. Pelatihan ini menunjukkan hasil yang menjanjikan: keripik limbah tahu berpotensi menjadi produk yang layak jual dan mendukung pengembangan industri rumah tangga. Inisiatif ini berpeluang meningkatkan kesejahteraan dan memperkuat ekonomi masyarakat Gampong Lengkong.

Abstract

AbstrakMangrove sangat penting bagi kehidupan biota pesisir dan laut, dimana telah mengalami kerusakan dan juga telah dilakukan rehabilitasi. Kajian komunitas fauna makrozoobentos di kawasan reboisasi mangrove Kepulauan Seribu berdasarkan faktor lingkungan, distribusi, ekologi komunitas, pola sebaran dan hubungannya telah dilakukan pada bulan Maret 2014. Hal ini bertujuan untuk mengetahui faktor lingkungan, distribusi, ekologi komunitas, pola sebaran serta hubungannya. Faktor lingkungan diukur secara in situ, sedangkan fauna makrozoobentosnya dikumpulkan dengan transek garis dan plot. Kemudian ekologi komunitas fauna makrozoobentosnya dilihat berdasarkan indeks keanekaragaman, dominansi maupun keseragaman, sedangkan pola penyebarannya dianalisis dengan indeks morisita serta hubungan antara faktor lingkungan, ekologi komunitas dan pola penyebarannya dianalisis menggunakan regresi linier sederhana. Faktor lingkungan yang diukur tidak begitu berbeda dan juga tidak melebihi baku mutu. Sebanyak 6 spesies dengan 3 kelompok fauna makrozoobentos telah ditemukan di kawasan reboisasi mangrove Kepulauan Seribu. Kemudian indeks keanekaragaman maupun keseragamannya tergolong rendah, dominansinya tergolong tinggi dan pola penyebarannya tergolong seragam (uniform). Selain itu, hubungan antara faktor lingkungan (suhu, salinitas dan DO perairan) dengan indeks keanekaragaman maupun keseragaman berkorelasi positif, sedangkan hubungan antara faktor lingkungan dengan indeks dominansinya berkorelasi negatif. Kemudian korelasi antara faktor lingkungan dengan pola penyebaran berkorelasi positif (membentuk kelompok) dan korelasi antara ekologi komunitas (keanekaragaman dan keseragaman) dengan pola penyebarannya juga berkorelasi positif serta membentuk kelompok.Kata kunci: fauna makrozoobentos; reboisasi mangrove; faktor lingkungan; distribusi; ekologi komunitas; pola sebaran; Kepulauan SeribuAbstractMangrove ecosystems are essential for the life of coastal and marine biota, which have been damaged and have been reforested. Study macrozoobenthos fauna community in mangrove reforestation area of Kepulauan Seribu was conducted in March 2014. This aimed to assess the relationship between environmental factors, distribution, ecology, and distribution patterns of the macrozoobenthos fauna community. The environmental factors were measured in situ, and macrozoobenthos was collected using line and plot transect. The ecology of macrozoobenthos fauna was analyzed based on diversity, uniformity, and dominance index. Distribution patterns were analyzed using Morisita index, and their relationships were analyzed using linear regression. Six species from 3 groups were found in this area. Diversity and uniformity index was classified low, dominance index was high, and the distribution patterns were relatively uniform. In addition, the relationship between the environmental factors (temperature, salinity, and DO) with diversity and uniformity index were positively correlated, and relationship between the environmental factors with dominance index were negatively correlated. The correlation between environmental factors with distribution patterns were positive (form groups), and the correlation between community ecology with distribution patterns were positive.Keywords: community ecology; distribution; Kepulauan Seribu; mangrove reforestation; macrozoobenthos fauna

Abstract

In Aceh Province, tiger prawns (Penaeus monodon) are one of the main commodities of farmers for cultivation. Feed is one of the factors that can support the development of tiger prawn culture. The quality feed is feed that contains essential nutrients in sufficient quantities, one of which is protein. This study aims to determine the effect of commercial feed with different protein content on the growth and survival of tiger prawn fry. This study used a completely randomized design (CRD) method consisting of 3 treatments and 4 repetitions, namely P1 (using 40% protein feed), P2 (using 35% protein feed), and P3 (using 26% protein feed). The results showed that commercial feed with different protein content had an effect on active weight growth and feed conversion ratio, but had no effect on tiger prawn survival. Furthermore, the best protein content for the growth and survival of tiger prawn was obtained, namely 40%.Keywords: commercial feed; growth; protein; survival rate; tiger prawn.

Abstract

This study aims to determine the effect of giving GDM probiotics on maintenance media on water quality and growth of pomfret fish. The method used was a completely randomized design (RAL) with 4 treatments and 3 replications, namely P0 (without the addition of probiotics). P1 (addition of probiotics 1.5 ml/L). P2 (addition of probiotic 2.0 ml/L) and P3 (addition of probiotic 2.5 ml/L). Each treatment used seeds measuring 4-5 cm. Parameters observed during the study were water quality, absolute weight growth (PBM), absolute length growth (PPM), survival rate (SR), and specific growth rate (SGR). Based on the analysis of variance, it was found that the treatment given had a significant effect (P<0.05) on absolute weight growth, absolute length growth, SR survival rate, and specific growth rate. Also, based on Duncan's test, treatment P1 (1.5 ml/L) was the best treatment.
