Abstract

Tujuan dari penelitian ini adalah untuk mengetahui diversitas jenis plankton di sekitar kerang kima dan keterkaitan antara diversitas plankton terhadap warna kima di beberapa pulau-pulau kecil di Teluk Lampung. Variabel yang diamati adalah jenis kima yang ditemukan dan keberagaman plankton yang berada di sekitar kima, variable pendukung yakni factor lingkungan. Data plankton yang diperoleh kemudian dianalisis menggunakan rumus indeks keragaman, keseragaman, dan dominansi. Penelitian ini telah dilaksanakan pada bulan Agustus-Oktober di perairan sekitar Gosong Susutan, PulauKelagian, dan PulauUnang-Unang. Hasil dari penelitian menunjukkan bahwa kerang kima yang ditemukan pada tiap lokasi berjumlah satu dan termasuk spesies Tridacna squamasa. Kelompok fitoplankton yang ditemukan antara lain Bacillariophyta, Pyrrophyta, Cyanophyta, dan Chlorophyta. Bacilllariophyta adalah kelompok yang paling banyak ditemukan pada ketiga lokasi penelitian (52-59%), sementara Chlorophyta adalah kelompok yang paling sedikit ditemukan (3-5%). Banyaknya Bacillariophyta yang ditemukan di sekitar kima menyebabkan mantel kima berwarna kuning kecoklatan seperti warna pigmen yang dimiliki oleh kelompok ini. Hasil parameter lingkungan menunjukkan masih dapat mendukung kehidupan kerang kima.

Abstract

The aim of this research was to find out the effect of probiotic on blood cholesterol in laying hens. Materials used were laying hens (Isa Brown strain) 43 weeks old and ration using probiotics. This research was conducted by using completely randomized design (CRD). The advanced research was done with testing the local probiotic with various concentration treatment, they are P0 (ration without probiotic), P1 (ration + 1% local probiotic), P2 (ration + 2% local probiotic), and P3 (ration + 3% local probiotic) with 5 time repetitions and in every repetitions consists of 2 chicken. Variables that were observed in the advance research were laying hens’s blood cholesterol that consists of total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, and total leucocyte. The level of total cholesterol on P0, P1, P2, and P3 were 129.00±38.26, 116.00± 26.53, 121.00±33.72, and 137.00±52.53 mg/dL (P0.05) respectively; the HDL level were 50.60±16.47, 35.80±11.28, 59.40±19.74; 56.80±30.56 mg/dL (P0.05); the LDL level were 100.20±49.53, 39.20±17.14, 104.60±51.23, and 96.80±66.22 mg/dL (P0.05), respectively; the trigycerides level were 862.00±355.5, 533.00±146.1, 829.00±242.6, and 810.00±304 mg/dL (P0.05), respectively; and leucocyte count were 22.00±1.72, 21.00±3.79, 31.00±3.99, and 34.00±3.55 x103 mm3 (P0.01), respectively. In conclusion, the administrtion of local probiotic do not effect the blood cholesterol of layer chicken.

Abstract

Plastic waste will be degraded into microplastic which has a size of ≤ 5 mm. These microplastic particles change in size and color due to various natural processes that occur in the environment. The purpose of this study was to determine the shape, color and size characteristics of microplastics found around Pasaran Island. Sampling was carried out by taking microplastic samples in water and green mussels around Pasaran Island. Based on the research results, microplastic fragments, films, fibers, granules and foam were found. Microplastic colors consist of black, blue, green, yellow, red, clear, and white. Microplastic fragments, films and fibers were found in the <50µm to 1000 - 5000 µm size group. Granular microplastic types were found in the <50 µm to 100 - 500 µm size group and foam types were found in the <50 µm to 500 - 1000 µm size group.

Abstract

Planktons are microorganisms that live in aquatic habitats. Plankton is used as a quality bioindicator of a water body. Way Sekampung flows to several areas in Lampung Province. The existence of activities around the watershed such as settlements, agriculture, and industrial waste disposal is thought to affect the water quality of the Way Sekampung River. The purpose of this study was to determine the water quality of Way Sekampung River based on plankton community structure consisting of abundance index, diversity index, uniformity index, and dominance index. Water sample data were analyzed using chemical parameters namely pH, BOD, DO, Phosphate, Nitrate, and physical parameters namely temperature and Total Suspended Solid (TSS) which are used to determine the status of water quality standards. This research was conducted at the beginning of the dry season (April) and the beginning of the rainy season (October). Sampling used a survey method based on the Way Sekampung River segment. Sampling points were carried out before and after the Argoguruh Dam. The results showed that the water quality of Way Sekampung River at the beginning of the dry season (April) and the beginning of the rainy season (October) were moderately polluted based on the analysis of plankton community structure such as abundance index, diversity, uniformity, and dominance.

Abstract

Nile tilapia (Oreochromis niloticus) is a fish that is in demand because of its high economic value and thick meat. Tilapia is easy to breed, uncontrolled spawning can occur so that growth is inhibited. The growth of male tilapia is faster than females at the same age. To increase the growth rate, sex reversal is carried out towards males through immersion in steroid hormones. Bioactive substances contained in sea urchins are steroid compounds. The purpose of this study is to determine the effect of the length of immersion in sea urchin gonad extract (Diadema setosum) on the formation of male phenotypes of tilapia larvae and tilapia survival. The method used is a completely randomized design with 4 treatments and each treatment with 3 replicates at a dose of 4 mg/L with soaking times of 0, 12, 18, and 24 hours. Data are analyzed using SPSS 16 software with analysis of variance (One-way ANOVA). The results show that different lengths of immersion in sea urchin steroid extract at a dose of 4 mg/L affect the formation of male individuals. A soaking time of 18 hours is quite effective in directing the sex of fish to males by 66%. Immersion time also affects the survival of tilapia larvae.

Abstract

River pollution is a major problem in the water quality crisis due to certain factors, including human activities around the river ecosystem which are strongly suspected to be the main cause of the problem. The purpose of this study was to determine the diversity and abundance of macrozoobenthos and the level of water pollution in the Way Semah Pesawaran River. The research was conducted using three indicators of water quality: biological indicators in the form of macrozoobenthos, physical indicators in the form of temperature and brightness, and chemical indicators in the form of pH, DO, and BOD. Sampling was carried out at 3 stations with two points, namely the right bank and left bank points at each station. The method of determining the location and data collection using the purposive sampling method. Based on the results of the analysis of abundance, diversity, uniformity and dominance of macrozoobenthos obtained the ecosystem of Way Semah River waters showed mild to moderate polluted conditions with a range of 1.21 - 1.87

Abstract

Water pollution refers to the introduction of living organisms, substances, or other components by human activities that can degrade water quality or cause environmental harm. Gonad maturity level indicates the stage of readiness of prospective broodstock for the spawning process, assessed through visual and histological methods. This study aimed to assess water quality in the Way Awi River based on fish community structure and to evaluate the impact of sewage discharge on fish gonad maturity levels in Bandar Lampung's Way Awi River. Conducted between November and December 2023, this research sampled five points along the Way Awi River. Chemical analysis included pH, BOD, COD, and DO, while physical parameters such as temperature and TSS (Total Suspended Solids) were also analyzed. The findings indicate that the Way Awi River is moderately polluted, with no significant impact on the community structure, although there is a noticeable decrease in fish numbers from upstream to downstream. This study underscores the importance of understanding the risks associated with continuous disposal of waste into rivers.
