Abstract

Semakin meningkatnya permintaan pasar untuk ikan hidup terutama ikan bandeng (Chanos chanos), maka dibutuhkan penanganan untuk menjamin kelulushidupan dan menjaga tahapan produksi tidak terganggu aman sampai tujuan. Dalam memenuhi permintaan tersebut, pembudidaya ikan menggunakan transportasi dengan sistem tertutup untuk pengiriman yang memiliki jarak tempuh yang jauh. Anestesi ikan dengan ekstrak sereh dalam transportasi sistem tertutup belum pernah diujicobakan pada benih bandeng. Penelitian ini bertujuan untuk mengetahui pengaruh dan dosis terbaik ekstrak sereh untuk pembiusan benih bandeng dengan transportasi sistem tertutup. Penelitian dilaksanakan pada bulan Juni – Juli 2022 di Balai Besar Perikanan Budidaya Air Payau, Jepara. Penelitian ini menggunakan metode eksperimen, rancangan acak lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 kali ulangan dengan dosis esktrak sereh yaitu A (kontrol), B (0,025 ml/L), C (0,05 ml/L) dan D (0,075 ml/L) di transportasikan dengan lama waktu 8 jam dengan simulasi buatan. Ikan uji yang digunakan adalah benih bandeng dengan panjang 7-15 cm. Bahan uji menggunakan ekstrak sereh dengan kepadatan ikan setiap kantong 10 ekor/liter. Parameter pengamatan adalah tingkah laku ikan selama pembiusan, lama waktu pemingsanan dan penyadaran, glukosa darah, kelulushidupan dan kualitas air. Hasil penelitian menunjukkan bahwa pemberian ekstrak sereh berpengaruh nyata (P<0,05) terhadap lama waktu pemingsanan dan lama waktu penyadaran, namun tidak berpengaruh nyata terhadap frekuensi bukaan operkulum, glukosa darah dan kelulushidupan. Dosis ekstrak sereh yang menghasilkan kelulushidupan rata-rata 90,00% pada perlakuan C dengan dosis 0,05%.

Abstract

Bakteri Pseudomonas sp. cukup banyak ditemukan menginfeksi ikan air tawar yang dibudidayakan di sepanjang Sungai Mahakam Provinsi Kalimantan Timur. Pemanfaatan bakteri dari usus ikan lokal yaitu ikan kelabau (Osteochilus melanopleurus) sebagai kandidat probiotik diharapkan lebih aman untuk mengendalikan infeksi tersebut. Penelitian ini dilakukan untuk menganalisa kemampuan empat isolat bakteri dari usus ikan kelabau yaitu BPs1, BPs2, BP3 dan BeP1 secara in vivo pada ikan kelabau dalam menghadapi infeksi bakteri Pseudomonas sp., yang meliputi tingkat kelangsungan hidup, jumlah bakteri patogen dalam darah dan parameter hematologi ikan kelabau. Ikan kelabau dengan berat 10,23±0,75 g masing-masing sebanyak 10 ekor dipelihara dalam akuarium dengan volume 30 L. Ikan diberi pakan komersil yang sebelumnya disemprot dengan isolat bakteri pada konsentrasi 106 CFU/mL dengan dosis 0,05 mL/g, sedangkan perlakuan kontrol pakan diberi larutan Phosphat Buffer Saline dengan dosis yang sama. Ikan diberi pakan tiga kali sehari secara at satiation dan penambahan bakteri dalam pakan dilakukan satu kali pada pagi hari. Perlakuan pakan diberikan sampai 13 hari, pada hari ke-14 ikan diuji tantang dengan bakteri Pseudomonas sp. yang diinjeksikan secara intramuscular dengan konsentrasi 106 CFU/mL dengan dosis 0,1 mL/ ikan. Ikan selanjutnya diamati sampai hari ke-21. Hasilnya menunjukkan bahwa penambahan isolat bakteri dari usus ikan kelabau mampu menekan infeksi Pseudomonas sp. Daya lindung terbaik ditunjukkan oleh isolat BPs2 (Staphylococcus edaphicus MT 269536) berupa tingkat kelangsungan hidup ikan, jumlah bakteri patogen dalam darah dan parameter hematologi dibanding perlakuan lain terutama kontrol (p>0.05). Berdasarkan hal tersebut bakteri dari usus ikan kelabau berpotensi sebagai probiotik dalam budidaya ikan air tawar.

Abstract

ARTICLE HIGLIGHTS- Nickel mining activities significantly impacted the ecological integrity of the Pomalaa coastal area in Southeast Sulawesi, particularly in the mangrove ecosystem.- The exposure of overburden waste in the mangrove ecosystem has led to the loss of important gastropod species and a decline in population of surviving species- The low population of gastropod species in nickel mining impact areas indicates extensive environmental damage caused by these activities.ABSTRACTGastropod resources in the Dawi-Dawi mangrove ecosystem, Southeast Sulawesi are greatly influenced by the input of overburden waste (sediment) from nickel mining activities. This condition has been going on for the last 2 decades and has degraded the habitat and structure of the gastropod community. The upstream connectivity (the existing nickel mining area) and the Dawi-Dawi River estuary mean that the mangrove forest (estuary) in this area is continuously affected by (massive) overburden runoff. This research was carried out in June-August in the mangrove ecosystem of Dawi-Dawi Village, Southeast Sulawesi Province. This research aims to determine the existing condition of mangrove gastropods affected by overburden. This research began by conducting initial observations in the field, to identify mangrove ecosystems affected by overburden. research stations were determined using a purposive sampling technique (targeted) and sampling gastropods using a simple random sampling method. The ecological index of the mangrove gastropod community affected by overburden shows a tendency for a medium diversity index (H'=1.81), low species richness (R=1.42), high evenness (E=1.12), and no dominance of certain species (C=0.19). The gastropod species found are typical types that make up the mangrove fauna, namely Terebralia sulcata, Terebralia palustris, Faunus ater, Telescopium telescopium, Hebra nigra, and several taxa (genus) of climbing Littoraria snails (periwinkle) which are found in the roots, stems and leaves of mangroves. The abundance of gastropods obtained was also very low, namely around 0-12 Ind./m2. At some points (rarely) schools of small snails of the type T. sulcata (5-21 Ind./m2) are sometimes found. This research shows de facto that overburden waste eliminates (survival) or reduces the diversity and richness of gastropod species (ecological index) in the mangrove ecosystem of Dawi-Dawi.

Abstract

Bakteri Aeromonas hydrophila adalah patogen penyebab penyakit Motile Aeromonas Septicemia (MAS) pada ikan mas dan umum dijumpai di Indonesia. Pengendalian bakteri ini dilakukan dengan menggunakan bahan kimia dan antibiotik yang dikhawatirkan dapat membahayakan lingkungan budidaya dan konsumen yang mengonsumsi ikan tersebut. Oleh karena itu, diperlukan bahan alami yang ramah lingkungan, dapat menghambat pertumbuhan bakteri, serta efektif menyembuhkan penyakit MAS. Lidah buaya (Aloe vera) adalah salah satu bahan alami yang dapat digunakan sebagai obat ikan karena memiliki aktivitas antibakteri yang mampu mengobati ikan mas dari infeksi A. hydrophila. Penelitian ini bertujuan untuk mengetahui efek ekstrak lidah buaya sebagai antibakteri, serta pengaruhnya terhadap status kesehatan ikan mas yang terinfeksi A. hydrophila. Efek antimikroba ditentukan secara in vitro dengan metoda cakram dan dilanjutkan dengan bioassay (empat perlakuan dan tiga kali ulangan) dengan merendam ikan mas yang sudah diinfeksi A. hydrophila dalam ekstrak lidah buaya dengan dosis sebagai berikut, perendaman ikan 0 ppm (A), 250 ppm (B), 500 ppm (C), dan 750 ppm (D). Data yang dikumpulkan meliputi ukuran zona hambat, gejala klinis, jumlah A. hydrophila, profil darah, bobot mutlak, SGR, kelulushidupan, dan kualitas air. Ekstrak lidah buaya menghasilkan diameter zona hambat berkisar antara 7,33-11,02 mm. Perendaman dengan ekstrak lidah buaya berpengaruh nyata terhadap jumlah bakteri, profil darah, pertumbuhan, namun tidak berpengaruh nyata terhadap kelulushidupan ikan mas. Perlakuan D (dosis ekstrak lidah buaya 750 ppm) memberikan hasil terbaik dari semua parameter yang diukur. Aeromonas hydrophila is common carp pathogen that cause Motile Aeromonas Septicemia (MAS) disease and commonly found in Indonesia. Control of this bacteria is carried out using chemicals and it is worried that they can harm aquaculture environment and consumers who consume the fish. Therefore, it is required natural ingredients that are environmentally friendly, can inhibit bacterial growth, and effectively cure MAS. Aloe vera is one of the natural ingredients that can be used as fish medicine because it has antibacterial activity which is expected to be able to treat carp from A. hydrophila infection. This study aims to determine the effect of aloe vera extract as an antibacterial, and its effect on the health status of common carp that attacked by A. hydrophila. The antimicrobial effect was determined in vitro using disc method and continued by bioassay (four treatments and three replications) by immersing carp that infected by A. hydrophila in aloe vera extract with immersion doses of 0 ppm (A), 250 ppm (B), 500 ppm (C), and 750 ppm (D). The data collected included the size of inhibition zone, clinical symptoms, number of bacteria, blood profile, absolute weight value, SGR, SR, and water quality. Aloe vera extract produces inhibition zone diameters from 7,33-11,02 mm. Immersion in aloe vera extract had significant effect on the number of bacteria, blood profile, growth, but had no significant effect on the survival rate of common carp. Treatment D (dose of aloe vera extract 750 ppm) gave the best results from all parameters measured.

Abstract

The biggest problem that often found in barb hatcheries are the poor hatching rate of eggs. One of the causes of low hatchability is infestation of fungi such as Saprolegnia sp. Prevention of the infestation of fungi could be done by adding natural ingredients such as plants leaves that contain antifungal, such as Jatropha leaf. Soaking Jatropha leaf solution aims to protect the chorion from being infestated by fungi so that it can minimize hatching failure of eggs. The purpose of this study was to determine the effect of soaking Jatropha (Jatropha curcas L.) leaf solution on the hatching rate and survival rate of Java barb (Barbonymus gonionotus) eggs. The testing eggs which were used on this study were originated from male and female broodstock aged 1-1.5 years. Experimental method was carried out using a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The treatments were Jatropha leaf solution at dosages of A (0 g/l), B (2 g/l), C (4 g/l), and D (6 g/l). The data observed were embryonic development, hatching rate (HR), survival rate (SR), and water quality. The results showed that treatments C and D demonstrated fastest embryonic development and hatching phase achieved at 475 minutes. Furthermore, treatment C showed the best value with HR (84.00±3.16%), SR (85.24±1.00%). It can be concluded that soaking eggs using Jatropha leaf solution at concentration of 4 g/L significantly improved hatching rate and survival rate of Java barb (Barbonymus gonionotus). Keywords: Jatropha, Java barb eggs, hatchability, fungi

Abstract

This study aims to analyze the relationship between salinity and the extent and type of mangrove vegetation in ponds within the Mahakam Delta, East Kalimantan. Sampling was conducted in ponds with different salinity levels: 0–10 ppt, 11–20 ppt, and 21–30 ppt, with each salinity category represented by 10 pond plots. Data analysis was performed using linear regression. The results showed a strong relationship between salinity variation and pond area, with an r-value of 0.630. The extent of pond expansion is related to the original mangrove type present in the pond area. This information can be used as a basis for determining suitable aquatic species for cultivation based on salinity levels. In other words, the selection of aquatic species for cultivation can be adjusted according to the appropriate pond area. Further research is needed to determine whether other factors influence the relationship between salinity levels and pond area in the Mahakam Delta region.

Abstract

Seaweed farming needs essential nutrients for growth. Nitrate and phosphate are essential nutrients for the growth of seaweed algae and phytoplankton produce chlorophyll-a. Chlorophyll-a content is needed in the photosynthesis process and triggers seaweed metabolism to absorb more nutrients. This study describes the relationship between nitrate, phosphate, chlorophyll-a for west and east monsoon waters with other water quality parameters in Tarakan Island. Insitu and exsitu measurements of water quality samples at 14 stations were determined by stratified random sampling in March 2024 for the west monsoon and June 2024 for the east monsoon. The distribution of chlorophyll-a was obtained from observations of the JAXA GCOM-C OCEAN CHLA V3 satellite image and the ocean contour model from BIG. There are significant differences in the distribution of chlorophyll-a, phosphate, and nitrate in the west and east monsoons. Chlorophyll-a distribution in the west monsoon of 0.60-1.10 mg/m3 tends to be higher than that in the east monsoon of 0.50-0.85 mg/m3 divergent pattern and correlates with nitrate, phosphate, water brightness, turbidity, sea surface temperature, current and pH. Water quality in the east and west monsoons supports seaweed farming.  Budidaya rumput laut membutuhkan nutrien penting untuk pertumbuhannya.

Abstract

The Pomalaa mangrove ecosystem in Southeast Sulawesi primarily consists of the gastropods Faunus ater and Terebralia sulcata. The Pomalaa District is the largest nickel mining area in the region, and mining activities have significantly impacted the ecosystem by introducing overburdened sediment waste, visibly affecting the substrate, roots, and stems of mangroves. This research was conducted from June to September 2023 in the mangrove ecosystem of the Pomalaa District. This study examined the density differences of gastropods F. ater and T. sulcata in areas impacted by nickel mining overburden compared to minimally disturbed sites in the Pomalaa mangrove ecosystem, Southeast Sulawesi. Sampling was conducted using purposive and simple random sampling techniques. Gastropod samples were obtained (counted), analyzed for density, and associated with mangrove density in the sampled area. The results showed that the highest densities of F. ater and T. sulcata were found in areas not affected by nickel mining overburden (reference sites) with ranges of 50-153 ind./m2 and 24-57 ind./m2, respectively. In contrast, in the areas affected by overburden, the population densities of the two types of gastropods ranged from 0-11 ind./m2 for T. sulcata and to 0-21 ind./m2 for F. ater) despite having high mangrove densities in several places. The distribution pattern of these two species was in the clumped category. This study found a significant decrease in the density of two typical mangrove slug species in overburden-affected areas compared to the reference sites. Keywords: gastropod, mangrove, overburden, nickel mining, species density
