Abstract

The phylum Coelenterata, class Anthozoa, includes a group of marine living things known as corals. Corals feature a variety of incredibly gorgeous colors and patterns. The majority of the world's more than 70,000 coral species may be found in tropical marine environments. Due to its geographic setting, Indonesia has an extremely high level of coral diversity and is the world's largest exporter of ornamental coral. Demand on the market for natural ornamental corals is now rising, along with trends in the rate of industrial development. Allowing this industrial activity to grow will result in huge exploitation and put the coral reef environment at danger. Therefore, to quickly increase the number of corals, this research examined transplantation methods. The montipora and echinopora genera were the focus of this study. The Montipora capricornis coral sample from PT Tirta Samudra Bali had the highest growth rate of the Montipora genus corals there, with an average growth rate of 1,404 cm2/week. The highest growth rate of the Echinopora genus corals had an average growth rate of 0.362 cm2/week. As they have a 100% survival record, cultivation activities using the transplant method performed at PT. Tirta Samudra Bali are regarded as successful

Abstract

Crowds of flies will add to the burden of everyday life. Moreover, if the flies try to eat the fly, they will be caught in the trap placed in the container's open mouth. Therefore, the fly population at X Hospital, Tulung Agung, should be controlled to a non-hazardous extent. This study analyzes the practical design for catching flies in the temporary hospital waste collection area. Fly traps are designed based on design criteria. Where fly traps can be made of wood and wire mesh to form a cylinder, inside which the flytrap is placed cone-shaped wire mesh. The fly trap, which has a length of 165 cm, a width of 180 cm, and a height of 30 cm, will be applied in a closed container with a capacity of 6 m3 and dimensions of 3.3 meters in length, 1.8 meters in width and 1.2 meters in height. This eco-friendly fly trap is made using perforated anti-mosquito wire mesh and arranged on top of the container. At the same time, the flies obtained can be used according to the needs that will be used.

Abstract

Sonar is a technology that uses the propagation of sound waves to detect the position of an object. Usually, fishermen use sonar to detect fish locations. The problem is that the price of sonar is still expensive, so not all fishermen can afford to use it. One of the devices that can be developed is the HC-SR04 module. HC-SR04 has simple components, and the price is cheap. The use of HC SR04 is still very minimal, so it is necessary to analyze the accuracy of its distance readings on various objects and conditions. The research was conducted using experimental methods in August-September 2023 at the Fishing Exploitation Laboratory, Faculty of Fisheries and Marine Sciences, Brawijaya University. The distance data generated by HC-SR04 is used to measure ceramic, Styrofoam, and fish. Based on the research results, it is known that ceramic and styrofoam objects have a calculated t value = 0 while the one-tail Critical t = 1.65, which means the average distance produced by the tool is the same as the average distance by manual measurement. Meanwhile, in the t-test, the fish samples obtained a value of t stat = 23.24 and t Critical one-tail = 1.65. This shows that the tool will show distance measurement results that differ from manual measurements. Furthermore, the RMSE value of distance measurements on ceramic and Styrofoam objects obtained an average value of 0, which means the measurements are very accurate. Meanwhile, the average RMSE value for fish objects = 37.67, which means that the tool measurements are inaccurate.

Abstract

Lamongan Regency has a fairly progressive fisheries sector with high fishing activity, such as the fishing industry and ports, especially in the Paciran and Brondong subdistricts. On the other hand, rapid fishing activities can also cause the entry of pollutants such as heavy metals and have the potential to reduce water quality in the area. The aim of this research is to analyze water conditions based on physical and chemical parameters as well as the distribution of dissolved heavy metal Hg and Pb in the fisheries industrial area and port of Lamongan Regency. The research was carried out using a purposive sampling method at seven stations along the waters of both Brondong and Paciran Districts. The data used in this research includes water quality parameters and dissolved heavy metal Hg and Pb. Analysis of heavy metal content was carried out in the laboratory using an Atomic Absorption Spectroscopy (AAS) instrument. The results showed that the heavy metal Hg at all stations was not detected by AAS because its concentration was very low. Meanwhile, the heavy metal Pb shows varying values at all stations with a range of 0.08 mg/L – 1.88 mg/L. The concentration of the heavy metal Pb at most location points has exceeded the limits set by Indonesian Government Regulations. The results of statistical analysis show that there is a relationship between temperature and pH and the concentration of the heavy metal Pb in water.

Abstract

The Community-Based Water Supply and Sanitation Program (PAMSIMAS) is one of the government's concrete actions to meet water needs in the community. However, implementing the PAMSIMAS program in Kebonagung Village needs more community involvement.  Therefore, this study is conducted to identify the level of community participation using frequency distribution calculations based on Arnstein's participation ladder. Data collection was conducted through a primary survey with 41 respondents using a simple random sampling method, using random respondents who would be used as research samples. The results showed that the level of participation in the PAMSIMAS program in Kebonagung Village was on the fourth ladder of participation, namely consultation with classification into tokenism, which means that the community participates in obtaining information and has the opportunity to argue for decision improvement but is often not accommodated or ignored. It is necessary to increase community participation by paying more attention to community needs so that the sustainability of the PAMSIMAS program continues.
