Abstract

AbstrakIkan gurami (Osphronemus gouramy) merupakan komoditas ikan air tawar yang bernilai ekonomis penting tetapi mempunyai kendala dalam budidaya, salahsatunya pertumbuhannya lambat. Salah satu pemecahan masalahnya adalah dengan pemenfaatan probiotik pada pakan. Penelitian ini bertujuan untuk mengetahui pengaruh fortifikasi probiotik dalam pakan dan untuk mengetahui penggunaan jenis probiotik terbaik dalam pakan untuk meningkatkan pertumbuhan ikan gurami (O. gouramy). Penelitian ini menggunakan metode eksperimen skala laboratorium dengan memberikan probiotik dalam pakan menggunakan rancangan acak lengkap (RAL) non faktorial dengan empat perlakuan dan tiga kali ulangan. Hasil penelitian dengan penyemprotan probiotik yang berbeda dengan dosis yang sama menunjukkan pengaruh yang sangat nyata terhadap pertumbuhan bobot, pegaruh nyata terhadap pertumbuhan panjang dan tidak menunjukkan pengaruh yang nyata terhadap kelangsungan hidup dan konversi pakan. Perlakuan terbaik terdapat pada perlakuan D dengan penyemprotan probiotik yang mengandung bakteri Saccharomyces cerevisiae, Lactobacillus acidophilus, Bacillus subtilis, Aspergilus oryzae, Rhodopseudomonas, Actinomycetes dan Nitrobacter per 100 gram pakan dengan laju pertambahan bobot 34,26 %, laju pertambahan panjang 30,95 %, kelangsungan hidup 76,67 % dan konversi pakan 5,35 g.Kata kunci: gurami; probiotik; pertumbuhanAbstractGouramy (Osphronemus gouramy) is a commodity of freshwater fish which is economically important, but it has many problems in their culture, for example is slow growth.

Abstract

Banyaknya industri yang berkembang saat ini menyebabkan meningkatnya kadar logam berat seperti merkuri dalam perairan. Penelitian ini bertujuan untuk mengetahui kerusakan struktur jaringan lambung ikan kakap putih (L. calcarifer) yang dipaparkan pada [Hg (NO3)2] dengan konsentrasi yang berbeda. Dalam penelitian ini, ikan dipaparkan dengan konsentrasi 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm dan 9,97 x 10-1 ppm. Total ikan yang digunakan untuk histologi adalah 15 ekor. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi [Hg (NO3)2] maka kerusakan pada jaringan lambung ikan juga akan meningkat dan mempercepat waktu kematian ikan. Kerusakan yang terjadi yaitu Hipertropi pada sel mukosa lambung, hancurnya villi, terdapatnya ruang antar lapisan otot dan villi serta menipisnya lapisan villi pada konsentrasi [Hg (NO3)2] yang lebih tinggi. Many industries today lead to increased levels of heavy metals such as mercury in water. This research aims to determine the effect of different concentrations of [Hg (NO3) 2] to Asean Sea Bass (L. calcarifer): Gill Histology. In this study, this fishes was treated with 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm, and 9,97 x 10-1 ppm. Total fishes used for histological study was 15 fishes. Results of this research showed that increasing the consentrations of the [Hg(NO3)2] will also increase the damage on the stomach structure and fasten the mortality time of the fish. Damage that occurs is hypertrophy aand hyperplacia on epitel cells, , fuse of secundary lamellae and haemorhage on gill that were exposed to high consentration of [Hg(NO3)2].

Abstract

The growth of an organism can provide fundamental ecological data and serve as a primary parameter for describing an organism's population dynamics. Telescopium telescopium gastropods were studied in September 2021 using purposive sampling in the mangrove forest of Cut Mamplam Village, Aceh Province. This study aims to provide fundamental data for mangrove management in Indonesia. Data were collected by creating a 40 m perpendicular to the coastline line transect, followed by 10 x 10 m sample plots and five 1 x 1 m sub plots. Following the collection of samples, additional analysis of the density, length and weight relationship, demographic structure, spatial distribution patterns based on the Morisita index, and growth characteristics were conducted as unique characteristics when compared to T. telescopium in other areas analyzed using PCA. The study's findings indicated that the density was low (< 7 ind/m2), the allometric length and weight relationship was negative (b < 3), the dominant growth demographic structure was mature (dominant SL 79.36 – 86.34 mm), the distribution pattern was clustered (Iδ = 02.75), and the BT, BWL, and AL morphometrics, in particular, had a variance of 95.91%. Pertumbuhan suatu organisme dapat menyediakan data ekologi dasar dan merupakan salah satu parameter yang utama dalam mengambarkan dinamika populasi suatu organisme, sehingga kajian gastropoda Telescopium telescopium di hutan mangrove Desa Cut Mamplam Provinsi Aceh dilakukan menggunakan purposive sampling pada bulan September 2021 dengan tujuan sebagai data dasar dalam pengelolaan mangrove di Indonesia, dimana data dikumpulkan dengan cara membuat transek garis sepanjang 40 m tegak lurus garis pantai, kemudian dibuat petak-petak contoh berukuran 10 x 10 m dan selanjutnya dibuat sub plot berukuran 1 x 1 m sebanyak 5 sub plot.

Abstract

The study of ecological characteristics, health conditions and the level of vulnerability of mangrove degradation when initiating North Rupat as a Regional Aquatic Conservation Area (KKPD) was conducted in July 2018 with the aim of future baseline data and comparison. Data collection on the condition of mangrove vegetation is carried out by making line transects and plots drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland. The results of the study showed that 12 identified species. The diversity index and dominance are relatively low (H’ ≤ 2.0 and 0 < C ≤ 0.5), while the uniformity is classified as stable (0.75 < E ≤ 1). For the density of mangroves the highest category of trees is at Station 4 (2525 ind/ha ± 638.15), while the density of saplings and seedlings at Station 1 (2800 ind/ha ± 873.48 and 50000 ind/ha ± 17638.34), where Xylocarpus granatum is the dominant species in the tree and seedling category (Importance Value Index/IVI 191.74% and 240.80%), while Avicennia alba was for the saplings category (IVI 216.01%). In the main land part of the North Rupat KKPD area, the mangroves' health condition was increasingly threatened by destruction compared to the small islands around it. However, overall the level of vulnerability of mangrove degradation in the initiating area of North Rupat KKPD is still relatively low.

Abstract

The study was carried out in March 2022 at 8 observation stations in the Krueng Geukueh Harbor coastal protection facility in Aceh Province, using the visual encounter method for 120 minutes. The Shannon-Weaver diversity index, Simpson dominance, and Shannon-Weaver uniformity were used to generate the gastropod ecology index, while PCA was used to examine dominance by specific species and CA was used to analyze similarities in species composition. The study's findings included 20 species, 7 families, and a group of chitons. Gastropods Littorina angulifera, Echinolittorina puncatata, Nerita chamaeleon, Mauritia arabica, Thais mancinella, Morula musiva and Herba corticata are classified as rare (relative frequency < 20%); Littorina undulata, Nerita planospira, Cypraea mauritiana and Chiton sp. classified as occasional (relative frequency 21 – 40%); Littorina brevicula and Echinolittorina placida are relatively common (relative frequency 41 – 60%); Nerita albicilla, Nerita costata, Tylothais virgata and Tenguella granulata are relatively common (relative frequency 61 – 80%); and Thais (Thalesa) aculeata, Trochus radiatus and Cellana radiata were found to be relatively abundant (relative frequency > 80%). The gastropod diversity and uniformity indices were both low (1.49 and 0.48, respectively), where as the dominance index was moderate (0.52). The PCA analysis revealed that the dominant gastropod species were C. mauritiana, M. arabica, and M. musiva, and the CA analysis revealed the establishment of three groups based on the species composition discovered as a result of human activities near the study site.  Kajian dilakukan pada bulan Maret 2022 di 8 stasiun pengamatan pada bangunan pelindung pantai Pelabuhan Krueng Geukueh Provinsi Aceh menggunakan metode visual encounter selama 120 menit.

Abstract

Gastropoda banyak ditemukan di ekosistem mangrove dan sangat dipengaruhi oleh kondisi lingkungan maupun kerapatan hutan mangrove. Salah satu gastropoda yang ditemukan adalah Terebralia palustris yang sering dijadikan sebagai bioindikator kesehatan mangrove. Kajian T. palustris (Linnaeus 1767) dilakukan pada bulan September 2020 di hutan mangrove Pantai Payum Merauke Papua dengan 3 stasiun pengamatan. Kajian ini bertujuan untuk mengetahui kepadatan, hubungan panjang berat tubuh, kualitas dan penciri lingkungannya serta faktor penentu distribusi dan kepadatan T. palustris di Pantai Payum. T. palustris maupun mangrove dikumpulkan dengan membuat transek garis sepanjang 50 m tegak lurus garis pantai dan dibuat petak-petak contoh berukuran 10 x 10 m untuk mangrove serta 1 x 1 m (di dalam plot 10 x 10 m) untuk T. palustris. Hasil kajian memperlihatkan bahwa kepadatan T. palustris bervariasi di setiap stasiun pengamatan dengan kepadatan tertinggi berada pada Stasiun 2 (54,20 ind/m2) dan terendahnya pada Stasiun 3 (19,67 ind/m2). Pola pertumbuhan T. palustris bersifat allometrik negatif. Untuk kualitas lingkungan secara keseluruhan, hasil penghitungan memperlihatkan bahwa kerapatan mangrovenya tergolong tinggi (> 1000 ind/ha) dengan parameter kualitas perairan untuk suhunya berkisar antara 28,33 – 31,67°C, DO 5,60 – 7,67 mg/L, pH 6,83 – 7,53 dan salinitas 29,33 – 30,00‰. Analisis PCA memperlihatkan bahwa penyebaran stasiun pengamatan dan karakteristik lingkungan membentuk 2 kelompok dengan kelompok pertama Stasiun 3 dipengaruhi oleh salinitas, suhu, DO dan kerapatan mangrove yang tinggi, sedangkan kelompok kedua Stasiun 1 dan 2 dipengaruhi oleh pH yang tinggi serta diameter batang mangrove yang besar. Berdasarkan hasil analisis PCA, faktor penentu distribusi dan kepadatan T. palustris adalah suhu, DO dan kerapatan mangrove.   Many mangrove habitats contain gastropods, which are greatly influenced by environmental conditions and the density of mangrove trees. One of the gastropods discovered was Terebralia palustris, which is frequently employed as a bioindicator of mangrove health. A research of T. palustris (Linnaeus, 1767) was done in September 2020 at three observation sites in the mangrove forest of Payum Beach, Merauke Papua. This study aims to evaluate the density, the relationship between body length and weight, the quality and characteristics of the environment, and the distribution and density determinants of T. palustris in Payum Beach. T. palustris and mangroves were gathered by constructing a 50 m perpendicular to the seashore line transect and creating 10 x 10 m plots for mangroves and 1 x 1 m plots (within a 10 x 10 m plot) for T. palustris. The study revealed that the density of T. palustris fluctuated at each observation station, with the highest density occurring at Station 2 (54.20 ind/m2) and the lowest density occurring at Station 3 (19.67 ind/m2). The T. palustris growth pattern is negative allometric. The calculation findings indicate that the mangrove density is high (> 1000 ind/ha) and that the water quality parameters range from 28.33 to 31.67°C, DO 5.60 to 7.67 mg/L, pH 6.83 to 7.53, and salinity 29.33 to 30.00‰. PCA analysis revealed that the distribution of observation stations and environmental parameters formed two groups, with Station 3 influenced by salinity, temperature, DO, and a high mangrove density, and Stations 1 and 2 influenced by a high pH and a big mangrove trunk diameter. According to the results of PCA analysis, the distribution and density of T. palustris are determined by temperature, DO, and mangrove density.

Abstract

AbstrakRumput laut merupakan sumber daya hayati perairan yang telah diteliti mengandung sejumlah komponen bioaktif untuk meningkatkan kesehatan manusia seperti meningkatkan sistem imun atau bersifat sebagai imunomodulator.Penulisan artikel ini bertujuan untuk menjelaskan lebih jauh tentang sifat imunomodulator rumput laut, diharapkan tulisan ini dapat memberikan informasi ilmiah tentang rumput laut sebagai imunomodulator, sehingga nantinya dapat dikembangkan lagi penelitian ilmiah tentang pemanfaatan rumput laut sebagai imunomodulator.Rumput laut dapat meningkatkan sistem imun spesifik dan non spesifik melalui berbagai sel imun seperti sel makrofag, monosit atau sel limfosit melalui berbagai mekanisme di tingkat seluler.Sifat imunomodulator rumput laut dalam meningkatkan aktivasi makrofag terjadi melalui peningkatan proliferasi makrofag, produksi NO dan sekresi sitokin. Rumput laut juga dapat memodulasi aktivitas makrofag secara in vitro dan in vivo yaitu melalui ekspresi reseptor dan sitokin inflamasi seperti tumor necrosis factor (TNF-α) dan interleukin-1β (IL-1β)., produksi NO dan PGE2 dan ekspresi gen NOS-2 dan COX-2. Sifat imunomodulator rumput laut juga terjadi melalui peningkatan fungsi dan aktivitas limfosit. Ekstrak atau komponen bioaktif rumput laut dapat meningkatkan aktivasi limfosit, diantaranya menstimulasi aktivitas sel limfosit B yaitu melalui peningkatan produksi antibodi imonoglobulin (Ig), meningkatkan proliferasi sel T dan produksi subset limfosit T seperti CD4 dan CD8. Ekstrak rumput laut juga telah diteliti  mempengaruhi ekspresi mRNA untuk meningkatkan produksi  sitokin oleh Th1 seperti TNF-α dan IFN-γ, dan menurunkan sitokin yang diproduksi oleh Th2 seperti  IL-4 dan IL-10 serta  meningkatkan produksi IL-2 pada sel limfosit T.Kata kunci: rumput laut; komponen bioaktif; imunomodulatori; makrofagAbstractSeaweed is one of the marine biological resources that is known to contain bioactive compounds to improve human health, such as enhancing the immune system or being as an immunomodulator. This study aims to explain more about the nature of seaweed immunomodulators so that scientific research could be developed in the use of seaweed as an immunomodulator later. Seaweed could increase specific and nonspecific immune systems by involving various immune cells such as macrophage cells, monocytes, or lymphocyte cells through various mechanisms at the cellular level. The role of Immunomodulatory properties of seaweed in increasing macrophage activation occurs through increasing macrophage proliferation, NO production, and cytokine secretion. Seaweed would modulate macrophage activity in vitro and in vivo through the expression of inflammatory receptors and cytokines such as tumor necrosis factor (TNF-α) and interleukin-1β (IL-1β), NO and PGE2 production and NOS-gene expression 2 and COX-2. Seaweed immunomodulatory activity would also occur through increasing function and activity of lymphocytes that stimulate the activity of B lymphocyte cells, production of antibody immunoglobulin (Ig), T cell proliferation and production of T lymphocyte subsets such as CD4 and CD8. Seaweed extracts also have been investigated to be able to affect mRNA expression to increase cytokine production by Th1 such as TNF-α and IFN-γ, decrease cytokines produced by Th2 such as IL-4 and IL-10 and increase IL-2 production in T lymphocytes.Keywords: seaweed; bioactive components; immunomodulatory; macrophage
