Abstract

A water channel is a building made for the process of draining water. The water channel will drain water from a high place to a lower place. Waterways are commonly used to drain rainwater, irrigate rice fields and household wastewater. The problem that often arises in waterways is the accumulation of garbage. Garbage that accumulates can clog drains. Clogged drains can cause environmental problems such as flooding, water pollution, sources of unpleasant odors, and breeding grounds for mosquitoes. Garbage problems that arise in waterways must be addressed immediately. One form of solving the problem of piles of garbage in waterways is the process of monitoring the state of the waterways. The process of monitoring waterways aims as a form of monitoring the condition of waterways. In the current technological era, the process of monitoring water flow can be done remotely by utilizing internet of things technology. The monitoring process using internet of things technology can facilitate monitoring work because there is no need to visit the location to see the condition of the waterways. The design of monitoring waste piles in loRa-based waterways is a tool design to facilitate the process of monitoring waste in waterways. The monitoring process is carried out by paying attention to the water discharge to determine the condition of the water channel. The process of sending data on waterways uses the LoRa transmission system.

Abstract

Hydrogen is an alternative energy source that can be produced from renewable energy sources, such as biomass and is known as biohydrogen. In addition to abundant producing sources, biohydrogen is also environmentally friendly. But this biohydrogen industry will produce waste that will pollute the environment if simply thrown away. Industrial liquid waste can have a considerable impact on the environment, this waste can cause biological oxygen demand (BOD) and chemical oxygen demand (COD). The high value of BOD and COD produced by this waste resulted in it not being discharged directly into the environment and special treatment was needed in advance. Technology that can be used in handling waste problems, among others, is the utilization of microorganisms as an effort to speed up the process of decomposition of waste, especially organic waste into organic fertilizers. Biohydrogen waste contained in the biohydrogen fermenter tank, then filtered biohydrogen waste which was originally in the form of slury, liquid waste is discharged and solid waste is stored to be mixed with goat manure. A mixture of biohydrogen waste and goat manure is made with a ratio of 20: 80 ; 40:60 ; 60:40 and 80:20 after all the ingredients are well mixed then the sample is stored in a sealed container that has previously been fitted with a thermometer to measure the temperature of the compost. The compost mixture sample is then stored for 30 days and observed its temperature and pH every day, and measured the moisture content at the beginning of the composting process and the end of composting After 30 days of storage the compost mixture is then analyzed nitrogen (N), phosphorus (P), potassium (K) levels. In the research on making compost from biohydrogen waste with maja fruit raw materials obtained the best results, namely at a ratio of 60:40 with N levels of 0.05%, P levels of 0.15% and K levels of 0.61%.

Abstract

MIMO sectoral antennas are antennas that are often used and installed in BTS towers owned by cellular operators. The sektral antenna is useful for GSM, GPRS, and LTE communications. The gain generated by sectoral antennas is quite large compared to other antennas. As well as the resulting radiation pattern can select the area that can be reached. This research designs and builds a sekotral antenna with a working frequency of 900 MHz which will be used as a transmitter for bladeRF as the main radio. Designing and simulating the antenna is carried out on the MMANA-GAL software application. In order to get the desired parameters and results and to know the parameters of the antenna, it is necessary to design the antenna first. The parameters that will be obtained when measuring sectoral antennas in this research are SWR, Gain, radiation pattern, polarization, and impedance. After taking measurements and simulations, it is found that the difference in the results obtained from the experiment is that the performance of sectoral antennas is very good and can be used on real radio or in real conditions in the field. In the 4-element simulation, the SWR generated during the simulation is 1.22, the resulting gain is 13.17, the resulting impedance is 57.87, and the radiation pattern has an angle of 60o. Meanwhile, when testing using the Antenna Network Analyzer, it can only determine 3 parameters, namely impedance, SWR, and smitch chart. The resulting SWR is 1.4 which is not the same as the MMANA-GAL simulation results, then there is an impedance which has a good value of 54.6. Which value is close to the value of 50 but in the simulation the value obtained is greater. The thing that affects the values of these parameters is because during the simulation the array elements should be circular but instead formed a rectangle and the measuring instrument used is also still unstable when measuring in real terms on the antenna. This sectoral antenna can be used properly in GSM technology telephone communication at a working frequency of 900 MHz which will be used in the Software Defind Radio BladeRF

Abstract

The problems are happening at PT. XYZ regarding the work system. A good work system is a work system that has high efficiency and productivity values. So the role of industrial management is absolutely necessary in terms of designing a new system that can increase the production. Activities or linkages between elements are interdependent to achieve the same goal. In line with current problems, the purpose of this study is to determine the management of existing processes in a company that is influenced by several factors. In addition, the output also affects the efficiency of existing work productivity. The results of this study indicate that an engineering project is needed to increase the existing effectiveness. To be able to produce products with good quality and in accordance with standard operating procedures in making products. The company must carry out quality control by taking into account the level of defects produced in production. In order for the defect level of a product to be close to zero defect or if none is equal to zero, it is necessary to make a repair which of course will require quite a long time and a lot of money. By using quality control, it is hoped that a company can reduce the occurrence of defective products, and can reduce things that are not expected by the company in accordance with the vision and mission. There is a management system that can be applied, namely MBOS or better known as Management By Olympic System.
