Abstract
Black-winged myna (Acridotheres melanopterus) is an endemic species from Indonesia, which has no difference between male and female based on their morphological characteristic. It can be a problem for the breeders to identify the sex when they have to pair the bird. The aim of this research is to identify the differences between male and female black-winged myna based on morphometric characteristic. There are weight, length, width, circumference, and the spread of the wings. The data is processed using principal component analysis (PCA) on the SPSS 20 program. The samples are 71 black-winged myna with minimum two years of age from breeding facilities in Java and Bali islands. Based on the research, morphometric characteristic that distinguishes male and female bird mostly is their wingspan and their weight. Morphometric characteristics of the female myna are smaller than the male. This result is essential for breeders to minimize the risk of pairing the same sex bird.

Abstract
Microplastics (MPs) is the most contamination problem on the marine environment now, therefore a small pelagic fish like anchovies, can feed accidentally the microplastic. This research focused on the amount of abundance of microplastics in the anchovies. We measured the length and dry weight of the anchovies and isolated their digestive tracts. The digestive tracts were then digested with NaOH and sodium lauryl sulphate (SLS) technical grade. The microplastics had observed with the using microscope and confirmed with Fourier-transform infrared spectroscopy (FTIR). Here, the investigation result from anchovies digestive tract (Stolephorus spp.) sampled (n = 15). The total microplastics contamination from Talisayan harbor, East Kalimantan is 366 ± 3. 51 particles/individual. Kind of microplastics size range detected as categories: < 20 µm, 20 -50 µm, 50 -500 µm, 500 -1000 µm, and >1000 µm. Most of microplastics shapes from Talisayan harbor are microfilm (50%) and microfiber (29.59%). The type of polymers are confirmed by Fourier transform infrared (FTIR) spectroscopy as polypropylene, high-density polyethylene and foamed polystyrene nylon. Our findings reported that specific size range (50-500 µm) is the most majority of microplastics size range which are ingested by anchovies from Talisayan harbor. The microplastics are more dangerous if another contamination found together on it. On this investigation, the mercury contamination also tested and the result showed as not detected mercury contaminant. The anchovies are had the economic value and also small pelagic fish which are play as prey for the other big fish. The exposure are possible to the human by contaminated seafood diet.

Abstract
Solar Cell performances as a power plant do not only convert energy, so that electricity is generated, but in the study of power systems it becomes a major element that has an important role in the study of power systems. As a power system element, the Solar Cell acts as an element of electricity generation in this study modelled as a PV system and connected to the network, so it must meet the requirements of the electric power network operation. Through MATLAB / SIMULINK modelling and simulations, a 100 kW peak Solar Cell power plant has been modelled to connect to the network. From the simulation and analysis obtained, this Solar Cell model shows that the connected load affects the voltage condition but does not affect the frequency. The load power factor also affects the network, namely with a lower load power factor, it affects the voltage on the network.

Abstract
A monitoring technology for large area with low-cost and high efficiency is highly demanded. Wireless Sensor Network (WSN) is the solution for a monitoring technology. However, not all monitoring must be continuous, there are some monitoring that can be carried out periodically. Therefore, it is possible to invent a mobile sensor communication system on multicell networks. This research aims to implement a WSN system by collecting data from mobile sensors on multicell networks. The focus of research is on the design of mobile sensor communication with low-cost device as transceivers, namely NodeMCU. The design is implemented using 4 NodeMCU units, 3 of them are functioned as access points, while 1 unit is employed as a client connected to the sensor. The experimentation was conducted by varying transmission distances of sensors with and without barriers. Moreover, handover and blankspot areas are also included accordingly. The result of experimentation shows that the usage of low-cost devices has still a possibility to build monitoring mechanism on multicell networks even though the transmission power was significantly influenced by the availability of barriers.

Published: December 2019

Abstract
Operation of an electric power system through a transmission network that has limited capacity can cause system instability when the system is disturbance. This study aims to investigate the influence of dynamic loads on the electric power system oscillation damping. The interaction between the electric power system and dynamic load after and before interference is simulated through Simulink Matlab. Dynamic load models are developed from the Hill model based on load power responses due to voltage changes. While the electric power system model is based on a model developed by Demello, which is a Single Machine Infinite Bus System. Based on the two models, an overall block diagram is made that illustrates the interaction between dynamic loads and the electric power system. The results showed that there was an increase in the stability of the electric power system with dynamic load feedback and a decrease in the rotor angle and increase in voltage. So that it can be concluded that changes in dynamic load parameters affect the stability of the electric power system. This study can be used as a basis for studying the behavior of electrical power systems that experience greater disturbance with load feedback.

Published: December 2019

Abstract
One of an attractive solution for PV ac-module is flyback-type micro inverter since it has a number of advantages include simple control, stable current injection and potentially low-priced technique. But, it has high voltage ripple in the DC-link that may cause high harmonic distortion. Hence, a smooth DC voltage is required in order to maintain the total harmonic distortion within standard level. DC link voltage can be smoothened by using capacitor. However, the size of this capacitor is large and hence affects the weight and size of the inverter package. This paper proposes a control method to reduce harmonic level for flyback-type micro-inverter. MPPT (maximum power point tracker) technique used in this study is perturb & observe because it is the simplest online MPPT method with high efficiency. Several experiments are carried out to examine the effectiveness of the proposed method. The results show that the proposed method can reduce the harmonic level significantly and can be used as an alternative solution.
Small signal stability analysis due to the development of renewable energy generators in Sulawesi electricity
Authors: Darmawan H S , Hadi S P , Sarjiya S 
Published: December 2019

Abstract
The problem of small signal stability is one of the main problems in the current power system because the purpose of operating the system is close to the limit. Small signal stability is important because small disturbances in the form of non-dampened electromechanical oscillations have limited the power flow limit in a steady state, so the oscillation will affect the operating system in a security and quality review. The entry of renewable energy in the Sulawesi interconnection system certainly has an impact on system stability and the emergence of electromechanical oscillations. An estimated 75 MW of power will come from the PLTB that will be built in Sidrap and 62.5 MW in Jeneponto. This study aims to analyze small signal stability due to the development of EBT generators on the Sulawesi interconnection system through eigenvalue characteristics and participation factors. The PLTB that will be integrated in the Sulawesi system certainly affects power flow which has an impact on small signal stability.

Abstract
The Greenhouse is currently a necessity for urban landless people. To save energy, it is necessary to install photovoltaics on the roof of a mini greenhouse to supply electricity. The use of PV is very dependent on climate, temperature, and irradiation, therefore MPPT (Maximum Power Point Tracking) is needed to obtain optimal power. In this paper MPPT for stand-alone PV system based on PSO using input voltage and current of the boost converter is presented. The performance of PSO is validated by Simulink with irradiance and temperature variations. The use of PSO can achieve maximum power for various irradiance. MPPT based PSO was compared by a PV system without MPPT. Based on simulation results PSO provides the power improvement by 29.98 W. Simulation results show that the system designed can optimize power produced by PV.

Published: December 2019

Abstract
Induction motor slip ring-type technology has been widely used in industrial as one of the crucial electrical components to convert energy mechanically. The construction of this motor is more complex than other standardized induction motors such as squirrel cage. The complexity lies in the connection between the rings and brushes which requires more maintenance. Meanwhile, Squirrel cage motor that is supported by a Variable Speed Drive allows its user to start motor smoothly and adjusts the speed more efficiently. In this study, we exclusively investigate the possibility of the outdated technology replacement by using squirrel cage standardized induction motor based on its compatibility and the financial perspective as well. To prevent any coming up problems, the selections of new motor and VSD must fulfil the requirement of the existing system. Technical data were collected from customer’s SCADA and nameplates. While the financial calculation was made based on the payback period. In this case, the payback period is projected within two years and the energy saving could reach 69% that basically depends on operation patterns. According to our perspective, standard squirrel cage motor potentially replaces the slip ring motor in which it is not only having a simple operation but also less maintenance and energy cost.
