Abstract

Pasuruan Regency is a major industrial center in Indonesia where their heavy metal industrial waste accompanied by  , household waste, and agricultural activities polluted  Pasuruan waters. The purpose of this study was to determine the status of heavy metal pollution in the Pasuruan sea in the coastal areas of Kraton, Lekok and Nguling and to find out how to overcome it. The survey method was used in this study to analyze the levels of heavy metals (Hg, Pb, Cd) in the waters and calculate the water pollution status based on the pollution index and water quality. Water sampling is carried out at a depth of between 2-15 meters at 3 stationary lift nets (Bagan tancap) at each location. The results showed that the highest levels of heavy metals were found in Lekok waters. The results of the calculation of the pollution index (IP) show that Lekok water has a heavy pollution status for all types of heavy metals (Hg, Pb, Cd). The pollution status in Nguling and Kraton waters based on the Hg and Cd pollution index is classified as heavily polluted. Meanwhile, heavy metal levels of Pb still meet water quality standards. The results of measurements of temperature, pH, dissolved oxygen, salinity, and current velocity are classified as optimum for aquatic biota. Based on the research results, it is known that there are areas of Pasuruan waters that are heavily polluted. Therefore, better water quality management is needed to meet the needs of biota by planting Rizhophora mucronata mangroves.

Abstract

Air sisa budidaya ikan lele berupa bahan organik apabila dibuang ke perairan secara terus menerus dan berlebihan mengakibatkan pengkayaan nutrisi di perairan sehingga terjadi perubahan lingkungan. Upaya pengelolaan yang dapat dilakukan untuk menurunkan kadar bahan organik adalah dengan menggunakan metode bioremediasi dalam penelitian ini yaitu penambahan bakteri Bacillus subitilis. Tujuan dari penelitian ini adalah  untuk mengetahui pengaruh dinamika jumlah bakteri Bacillus subtilis dalam menurunkan kadar bahan organik pada limbah budidaya ikan lele Sangkuriang (Clarias gariepinus). Metode yang digunakan dalam penelitian  atau uji laboratorium adalah metode eksperimen dengan rancangan acak lengkap (RAL) faktorial dengan 2 perlakuan.  Adapun 2 perlakuan tersebut yaitu perlakuan waktu inkubasi (24, 48, 72, 96 dan 120 jam) dan perlakuan kepadatan bakteri yaitu 107 CFU/mL, 106 CFU/mL dan 105 CFU/mL, dengan ulangan sebanyak 3x dan pengolahan data dilakukan Uji ANOVA dengan menggunakan software SPSS (Statistical Package for Sosial Science) Statistic 23 dan software Minitab 18 untuk uji lanjutan Tukey. Kurva pertumbuhan bakteri bertujuan untuk mengetahui waktu bakteri memasuki fase logaritmik dan fase stasioner.  Hasil pengukuran Total plate count bakteri Bacillus subtillis mengalami peningkatan jumlah bakteri pada semua perlakuan kepadatan setiap 24 jam. Hasil kepadatan bakteri berkisar antara 2,44 x 105 CFU/ml sampai 5,3 x 107 CFU/ml. Selama masih ada bahan organik maka bakteri akan tetap berkembang, bakteri akan menurun seiring nutrientnya habis, jika menurunkan bahan organik dalam waktu 5 hari, tetapi untuk bakteri membutuhkan waktu lebih dari 5 hari bahan organik tidak terdegradasi 100%.

Abstract

Clarias and Nile tilapia ponds contain high organic matter levels which will be decomposed by bacteria. It also produces carbon dioxide, which can be utilized by phytoplankton for photosynthesis process. This research aimed to compare the types of phytoplankton and zooplankton in Clarias and Nila tilapia ponds for eutrophication and water quality control. The research was conducted in August-September 2020. The water samples were taken using plankton net to become 35 ml from Clarias and Nile tilapia ponds. Analysis of plankton abudance, diversity, Evenness and Dominance Index was carried out in the Laboratorium Hidrobiologi. The analysis result of the average abundance of phytoplankton in the Clarias ponds was 71.026 cell/mL (11 genera), and zooplankton was 93 ind/mL (4 genera). Meanwhile in Nile tilapia ponds was 1.503 cell/mL (9 genera), and zooplankton was 91 ind/mL (1 genus). The average of zooplankton in Nile tilapia pond was higher than in catfish ponds; since Clarias are carnivores while Tilapia are omnivores. The plankton diversity index of catfish pond was average 0.817, while in Nile Tilapia was average 0.553. The evenness ndex of catfish pond was average 0.5, while in Nile Tilapia was average 0,4. The dominance index of catfish pond was average 0.59, while in Nile Tilapia was average 0.77. The conclusion obtained is the type of phytoplankton in Catfish pond consisted of 11 genera (99.62%) and zooplankton of 4 genera (0.38%), while in Nile Tilapia pond the type of phytoplankton consisted of 9 genera (97.85%) and zooplankton of 1 genera (2.15%).

Abstract

Waters that are presumably contaminated with heavy metals need to be observed to ensure the level of pollution to perform water restoration. This study was aimed to determine the status of water quality based on heavy metal contents. The survey method was employed in this study, and it was conducted in Pasuruan sea waters in different seasons; September 2019 represented the dry season, and April 2020 represented the rainy season. The water sampling stations were chosen by using purposive sampling in three sampling locations: the sea waters of Kraton, Lekok, and Nguling districts. The heavy metals and water quality parameters were analyzed by using Storet Index. The results indicated that the highest level of heavy metals was found in Lekok waters in September, consisting of Hg (1.22 mg/l), Cd (1.20 mg/l), and Pb (0.55 mg / l). The seawater of Nguling district had the lowest content in April, while Kraton's seawater was moderate. The water quality status based on the Storet Index suggested that the sea waters of Kraton, Lekok, and Nguling districts were classified as moderately polluted with a score of -16 to -24. The highest score was in September in the rainy season with a score of -24 and the score in April in the dry season was -16. It means that the score is increasing but still in the moderately polluted category. The measurement results of temperature, pH, dissolved oxygen, salinity, and current velocity were in optimum results for aquatic organisms in the dry season or the rainy season. Regarding the water quality status in Pasuruan sea waters, it can be concluded that the heavy metal contents exceeded the quality standard set by the government. Therefore, improved management is required to prevent the deterioration of the pollution status in Pasuruan sea waters

Abstract

One way to help the feeding process vannamei shrimp in ponds that have cloudy surface using constructed with a size of 50 × 50 × 18 cm with a water height in the pond of 7 cm from bottom, where the data in the form of images was obtained from data collection 25 times using a camera is placed at a height of 52 cm above the water surface. The pond’s entire surface was captured with one click of the camera. The number of vannamei shrimp used in this study was 7. The method used for data processing is thresholding, in which the threshold value is generated using a histogram-based technique from the image data. This method is employed to distinguish shrimp from non-shrimp regions in the image. From this study, a vannamei shrimp detection technique was developed, producing results in the form of a script that distinguishes vannamei shrimp objects from non-vannamei shrimp. The detection accuracy achieved using the thresholding method in this study is 94.28%. The positions of the shrimp were produced in the form of coordinates as a step to success according to the objectives of this study, which were able to detect positions, in order to help facilitate the process of feeding in ponds. This detection technique could be developed for application on full-scale ponds, utilizing cameras mounted on drones as a tool for detecting vannamei shrimp positions in cloudy pond water. This technology may be adapted to allow targeted feeding of shrimp in ponds, thus maximizing food consumption and minimizing food wastage.

Abstract

Pakan merupakan salah satu unsur penting dalam perkembangan kegiatan budidaya yang menunjang pertumbuhan dan kelangsungan hidup ikan. Pakan pada kegiatan budidaya umumnya menggunakan pakan komer- sial yang menghabiskan sekitar 60-70% dari total biaya produksi yang dikeluarkan. Penelitian bertujuan untuk menganalisis pengaruh pemberian pakan maggot terhadap pertumbuhan ikan lele (Clarias sp.). Latar belakang penelitian ini didasarkan pada tingginya biaya pakan komersial dalam budidaya ikan lele, sehingga diperlukan alternatif pakan yang lebih ekonomis dan tetap mendukung pertumbuhan ikan. Maggot (Hermetia illucens) memiliki kandungan protein tinggi yang berpotensi sebagai pakan alternatif. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan pakan: (A) 100% pakan komersial, (B) 70% pakan komersial + 30% maggot, (C) 50% pakan komersial + 50% maggot, dan (D) 100% maggot. Parameter yang diukur meliputi pertumbuhan panjang dan bobot mutlak, laju pertumbuhan harian, rasio konversi pakan (FCR), efisiensi pakan, serta tingkat kelangsungan hidup ikan. Hasil penelitian menunjukkan bahwa perlakuan C (50% pakan komersial + 50% maggot) memberikan pertumbuhan panjang dan bobot tertinggi, dengan FCR optimal dan efisiensi pakan yang lebih baik dibandingkan perlakuan lainnya. Semua perlakuan menunjukkan tingkat kelangsungan hidup ikan sebesar 100%. Kualitas air selama penelitian pada kisaran yang layak untuk kelangsungan hidup ikan lele.
