Abstract

The increasing demand for fossil fuel energy (BBM) has driven the development of renewable energy sources, one of which is biodiesel derived from microalgae. Chlorella sp. is a promising microalga due to its high lipid content. This study aims to determine the optimal concentration of tempeh wastewater for culturing Chlorella sp. to maximize lipid production as a raw material for biodiesel. The culture was carried out for five days using different treatments of tempeh wastewater: 0% (control using Walne fertilizer), 3%, 5%, 7%, and 9%. Observed parameters included temperature, pH, dissolved oxygen, nitrate, phosphate, cell density, and lipid content, with lipid extraction performed using the Soxhlet method. The culture temperature ranged from 25-27°C, pH increased from acidic to neutral, and dissolved oxygen levels decreased at higher wastewater concentrations. The highest cell density was found in the 7% treatment (8.45 million cells/mL), although it was not significantly different from the other treatments. The highest lipid content was obtained at 3% wastewater (40.3%), which was higher than the control (21.3%) and other treatments. The decrease in lipid content at higher wastewater concentrations was attributed to toxicity and reduced media quality. It is concluded that a 3% concentration of tempeh wastewater is optimal for enhancing lipid production in Chlorella sp. as a sustainable biodiesel feedstock.

Abstract

Budidaya ikan hias memiliki potensi ekonomi tinggi, terutama pada skala UMKM, dengan margin keuntungan lebih besar dibandingkan ikan konsumsi. Salah satu jenis ikan hias populer adalah ikan guppy (Poecilia reticulata), khususnya jantan yang memiliki warna tubuh dan sirip menarik, sehingga memiliki nilai jual lebih tinggi. Desa Sindangsari, Kecamatan Sukasari, merupakan wilayah potensial untuk budidaya ikan guppy karena ketersediaan air yang memadai dan lingkungan yang mendukung. Budidaya di daerah ini telah menggunakan berbagai media pemeliharaan seperti kolam tanah, beton, dan plastik. Namun, salah satu tantangan utama adalah rendahnya proporsi anakan jantan. Solusi yang ditawarkan adalah penerapan teknologi pengarahan kelamin (maskulinisasi) untuk meningkatkan jumlah ikan jantan. Umumnya, maskulinisasi dilakukan menggunakan hormon sintetis seperti 17α-metiltestosteron yang berisiko menimbulkan dampak negatif terhadap lingkungan dan kesehatan ikan. Oleh karena itu, dibutuhkan alternatif alami seperti air kelapa yang mengandung kalium, berperan dalam biosintesis hormon steroid. Program Pengabdian Masyarakat (PPM) oleh Departemen Perikanan FPIK Unpad bertujuan memberikan penyuluhan dan pendampingan tentang pengaruh perendaman induk bunting ikan guppy dalam air kelapa terhadap proporsi anakan jantan. Kegiatan ini dilaksanakan pada 25 Juli 2024 bersama kelompok Mina Sari Barokah di Desa Sindangsari, dengan jumlah peserta sebanyak 21 orang. Peserta juga akan mendapat pendampingan selama pelaksanaan kegiatan.

Abstract

Water quality is an important factor in the process of fish farming. This study aims to determine the application of FBs pressure that can increase the productivity of comet goldfish farming in an aquaponic system. The research was carried out from January to March 2022 at the Ciparanje Green House, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor. This study used a completely randomized design (CRD) experimental method with four treatments and three replications. The treatment used was the application of FBs pressure of 0 atm (A), 5.25 atm (B), 5.5 atm (C), and 5.75 atm (D). Maintenance of test fish for 30 days with ad satiation feeding. Observation of fish growth through sampling is done by taking fish 10% of the total population randomly in each pond. Data were analyzed using the F test at a 95% confidence level, followed by Duncan's multiple range test with a 95% confidence level, while water quality data were analyzed descriptively. The results showed that the specific daily growth rate of FBs 5.75 was 2.51%, the absolute length growth was 3.33%, the absolute weight growth was 1.70 grams and the fish survival rate was 99.3%. It was concluded thatthe use of FBs in the aquaponic system can increase production of the system.

Abstract

This research examined the post-rehabilitation dynamics of the mangrove ecosystem in the Mangrove and Crab Conservation Area, Tarakan, North Kalimantan, four years after the launch of a community-based restoration program in 2019. The objectives were to evaluate species composition, vegetation structure, and the survival of mangrove seedlings within rehabilitated plots. The sampling was done on purpose in areas that show the main ecological features of the site. This study found five types of mangrove trees: Avicennia alba, Rhizophora mucronata, Avicennia marina, Sonneratia alba, and Xylocarpus granatum. It is fewer than the ten species that were there in the past. Among these, Avicennia alba consistently dominated both the mature and seedling stages, recording the highest relative density (72.56%), frequency (42.86%), and canopy cover (78.08%). Its naturally regenerating seedlings reached a survival rate of 52%, substantially higher than the 17% recorded for planted Rhizophora mucronata. The Avicennia alba is particularly well adapted to the prevailing site conditions, mainly owing to its tolerance of sediment disturbance and variable salinity. This outcome highlights the importance of Assisted Natural Regeneration (ANR) that employs locally adapted species, offering a more practical, cost-effective, and sustainable approach than conventional planting methods. Although there have been some improvements, the decrease in species numbers shows the ecosystem is still in the early stages of recovery. To make sure it stays healthy and strong for the future, it is important to keep the water flowing properly, reduce human impact, and keep up with regular checks and monitoring.

Abstract

Graphical Abstract Highlight Research The results of this research showed that allometric growth in males and females had negative allometric growth characteristics. The growth condition index in male and female fish is dominated by thin and fat body shapes.The maximum length growth (L∞) and growth speed of males is higher than that of females. Total mortality and fishing mortality for males is higher than for females, but natural mortality for females is higher than for males. The exploitation rate of males and females is in the Under-exploitation category because the E value is <0.5. Abstract Exploring the length-weight relationship of fish and characterising growth parameters is essential in fisheries as they offer fundamental biology and population dynamics data to establish good management strategies for fisheries resources. This study examines the growth and mortality patterns of Oreochromis mossambicus. Data was collected between September and December 2022 using quantitative descriptive survey sampling. The study involved 20 repeats and deliberate random sampling of 30-50 fish per sample, emphasising total length, weight, and sex parameters. Based on 726 samples of O. mossambicus (352 fish identified as male and 374 fish identified as female). The growth model study revealed the typical negative allometric growth for both sexes (male and female). Male individuals attained a length of 33.449 cm after 37 days has a growth trend ± 0.3265 year-1, and females reached 21.150 cm in 34 days with a growth rate around 0.3135 year-1, as per the von Bertalanffy growth model. There were complex mortality patterns, with males contributing to most total deaths. This study emphasises the complex biology of tilapia and its untapped potential in the aquaculture pond system ecology in Tarakan.

Abstract

Sungai Cikeruh merupakan Daerah Aliran Sungai (DAS) Citarum yang melintasi Kabupaten Bandung dan Kabupaten Sumedang, yang berada di kawasan tingginya padat penduduk, sehingga mengalami pencemaran pada perairan. Tercemarnya Sungai Cikeruh diakibatkan oleh masukan beban cemaran dari aktivitas antropogenik seperti limbah domestik, pertanian, dan industri yang memberikan suplai bahan anorganik atau unsur hara seperti nitrat dan fosfat. Ketersediaan unsur hara dapat diindikasikan oleh nilai produktivitas primer berdasarkan sebaran klorofil-a. Penelitian ini bertujuan untuk menentukan produktivitas primer serta faktor lingkungan yang mempengaruhi sebaran dan konsentrasi klorofil-a di Sungai Cikeruh. Penelitian ini dilaksanakan pada bulan Desember 2024 – Januari 2025, dengan metode survei dan teknik pengambilan sampel purposive sampling yang dilakukan di lima titik stasiun dengan 4 kali ulangan. Hasil dari pengujian kualitas air terdapat parameter yang tidak memenuhi baku mutu kualitas air berdasarkan Peraturan Pemerintah No. 22 Tahun 2021 yakni BOD dan DO. Nilai rata-rata BOD tidak memenuhi kelas 2 maupun kelas 3 pada setiap stasiunnya, sedangkan nilai rata-rata DO pada Stasiun 2 dan 4 tidak memenuhi baku mutu kelas 2  dan pada Stasiun 5 tidak memenuhi baku mutu kelas 3. Nilai konsentrasi klorofil-a di dapatkan nilai rata-rata 0,135-0,613 mg/L, berdasarkan uji statistik One-way anova konsentrasi klorofil-a didapatkan nilai p-value 0,086 > taraf signifikansi, yang diartikan tidak terdapat perbedaan yang signifikan pada setiap stasiunnya, hal ini dikarenakan perairan Sungai Cikeruh tergolong pada perairan oligotrofik melalui perhitungan produktivitas primer yang didapatkan yakni nilai rata-rata 15,998 – 40,300 mgC/m3/hari, hal ini menandakan bahwa unsur hara dan produktivitas pada Sungai Cikeruh tergolong rendah.
