Abstract

This research was conducted from October to November 2019 at the peatland of Kualu Nenas Village, Kampar District, Riau Province. The aim of this research is to get a comparison of the mixture between human waste biofertilizer and cow manure biofertilizer to increased the abundance of phytoplankton. The method used in this study is an experimental method using a completely randomized design (CRD), 1 factor with 6 treatment levels and 3 replications. The treatment used were P0 (without biological fertilizers), P1 (giving a mixture of biological fertilizer 100%), P2 (Biofertilizer mixture 25% human waste : 75% cow manure biofertilizer), P3 (Biofertilizer mixture 50% human waste : 50% cow manure biofertilizer), P4 (Biofertilizer mixture 75% human waste: 25% cow manure biofertilizer), P5 (Biofertilizer 100% human waste). The study was conducted for 28 days, using a dose of 750 g/m2. The results of this research showed that the application of a mixture of biological fertilizers 75% human waste: 25% biofertilizer cow manure gave the best results on the abundance of phytoplankton, namely 28,771 ind/L, the diversity index value (H') was 0.49, the species dominance value (C) was 1.10 and the peak of the population occurred on the 16th day. Water quality parameters measured during the study were still optimal for phytoplankton growth with a temperature of 27-29oC, pH 5-7, DO 3.8-6.7 ppm, nitrate 4.75 mg/L and orthophosphate 3.50 mg/L

Abstract

This research was conducted in February 2021 at the mouth of the Dumai River, Rupat Strait. The purpose of this study was to determine the effect of sediment supply from land on changes in bathymetry in the waters of the Rupat Strait based on the analysis of suspended sediment (SSC) and suspended solids (TSS) divided by the area of the study. The method used is a survey method. The results showed that as much as 26,94 tons/year of sediment entered the Rupat Strait and was distributed in the research area. Each part of the research area has a different bathymetric change value. This is presumably due to oceanographic factors in the waters of the Rupat Strait such as strong and weak river currents when entering the sea, the distance between the research area and the sediment supply source, human activities in each part of the study area, erosion along the river and abrasion at the river mouth. the presence of mangrove forests, dominant sediment types, sloping water topography, the cross-sectional width of the river as a sediment supplier, and suspended solids

Abstract

White snapper (Lates calcarifer) is a fish that has high economic value because it has entered a large export market. The obstacle in the cultivation of white snapper is that it requires a higher protein in the threshing phase compared to larger fish to increase the growth performance of white snapper. This study aims to determine the best lysine dose for increasing the growth performance of the white snapper in the threshing phase. The research design method used was a completely randomized design (CRD) with three treatments and three replications. The treatments given were artificial feed without the addition of lysine (KPKM), artificial feed with the addition of 0,15% lysine/kg of feed (KP A), and artificial feed with the addition of lysine 0,35%/kg of feed (KP B) for 56 days. The results obtained in this study were all parameters showed that the results were not significantly different between treatments (p> 0.05) for 56 days of maintenance. This is presumed because the levels of lysine in the formulated feed and the levels of lysine absorbed by the fish in the control treatment were higher than the other treatments. Then for the survival rate, the calculation result is 100% for all treatments. Based on the results obtained, it can be concluded that there is no best lysine dose in this study

Abstract

Bawean Island is one of the islands in Gresik Regency, East Java, where almost all its territory is a coastal environment. This region's tidal oceanographic condition is critical because this area has a lot of potential for marine tourism and relatively shallow waters. This study aims to determine the tidal characteristics in the waters of Bawean Island, East Java, using the Admiralty method. This method was chosen because it can calculate the tidal component with only 15 days of data and can be used in various water conditions. The data used is tidal data from the Geospatial Information Agency (BIG) on November 1-15, 2020. From this research, it can be concluded that tidal analysis using the Admiralty method produces nine components, including M2, S2, N2, K1, O1, P1, M4, MS4, and K2. The four components determine the type of tide, namely O1, K1, M2, and S2, with amplitude values of 11.79347, 30.14857, 55.72241, and 63.69851. The calculation with the Formzahl number equation yields a value of 0.3512 (0.25 <F <1.5), which means that the tidal type in Bawean Island, East Java, has a mixed type with a semidiurnal tendency (double daily).

Abstract

The increase in the human population causes the amount of organic and inorganic waste to increase. The decomposition of inorganic waste is relatively longer compared to organic waste, therefore it is very harmful to the coastal environment. The purpose of this study was to determine the type, weight, distribution, density, and to compare the density and type of inorganic waste at Sebalang Beach and Tanjung Selaki Beach. Garbage collection and measurement of oceanographic parameters were carried out directly from March to April 2020. Garbage was collected on a 100-meter transect following the shoreline at each point at high tide and low tide. Current and wave were measured at two points with four repetitions. Waste data is separated by type, weight and presented descriptively. The results showed that the amount of macro-debris waste was higher than meso-debris waste with plastic waste that was more dominant than other types of waste. Sebalang Beach has a higher density of trash than Tanjung Selaki Beach.
