Published: July 2020

Septic Tank is a shelter for solid materials of human waste (faeces) which will quickly fill up when there is no decomposition process by bacteria decomposers. The amount of bacterial decomposers in a septic tank is generally less compared to the accumulation rate, so it is necessary to supply bacteria decomposers. The addition of these microorganisms is very cheap when compared to the cost of desludging or drying beside being practical, healthy and environmentally friendly. The decomposing bacteria (microorganisms) will decompose the solid materials in the septic tank into water (H2O) and some gas (CO2).Microorganisms that can decompose or degrade human faeces are PAOs (polyphosphate accumulating organisms) by degrading the polyphosphate into phosphate. Microorganisms that play a role in the decrease of phosphates are bacteria and fungi. Aerobic bacteria such as Pseudomonas sp. is one of the phosphate-degrading microorganisms. This research used the Pour Plate and gram staining method for microscopic observation to find the morphology of Pseudomonas sp.

Authors: Setiawan I , Utomo A B S , Mitrayana
Published: July 2020

Thermoacoustic sound generators are devices that produce sound waves by using thermal energy. The output acoustic oscillations can be used to drive a linear alternator to generate electricity. The devices are environmentally friendly because they do not produce any exhaust gases and they can utilize waste heat to generate the sound. This paper presents an experimental testing of a three-stage thermoacoustic sound generator of a looped-tube type. Each thermoacoustic core was composed of a regenerator, a hot heat exchanger and an ambient heat exchanger. The regenerators were made of a tight stack of 30-mesh stainless-steel screens, with a length of 35 mm. The looped-tube was made of stainless-steel pipes with inner diameter of 68 mm and total length of 4.3 m. Atmospheric air was used as working gas within the looped-tube. Three electric heaters, each with input power of around 394 W, were used as the heat sources and installed at the three hot heat exchangers. It was found that the device started to generate sound when the average temperature difference between the hot and ambient sides of the regenerators reached 255 °C. After 45 minutes operation, the average temperature difference was 538 °C, producing sound waves with a maximum pressure amplitude of 2.6 kPa and acoustic power of around 4.5 W. Additionally, it was observed a sound frequency jump during operation, that was 83 Hz until the temperature difference reached 526 °C and jumped to 339 Hz after that. During transition, both frequencies existed with relatively lower pressure amplitudes.

Published: July 2020

Molucca Sea is a seismically active area in eastern Indonesia. An earthquake occurred near to Ternate City, Province of North Maluku (M6.8: depth 29 km) on July 7, 2019. To investigate the detail about the mechanism of the earthquake, we analyzed the moment tensor of the earthquake by applying the regional waveform inversion. We used three components waveform broadband data from 18 station of IA-net seismic network in this study. We carried out the deviatoric mode to determine the double couple and compensated linear vector dipole (CLVD) component of the earthquake. The position and origin time of the earthquake were calculated by a space-time grid search in vertical and lateral positions. The frequency band of 0.01 – 0.023 Hz is used in the inversion process to reduce the instrument low-frequency disturbance and the effect of inaccurate velocity model for the synthetic seismogram. The moment tensor inversion result shows that the source mechanism of the earthquake is transpressional fault. This result agrees well with the tectonic setting of the study area.

The orbital angular momentum state (OAM) of the photon can be theoretically evaluated from minus infinity to infinity, and the different orbital angular momentum states are orthogonal to each other. Therefore, in recent years, it has attracted wide attention from the academic circle and the industry. The purpose of this paper is to study the characteristics of single photon orbital angular momentum transfer based on information processing technology and to provide Suggestions for its technical optimization. Based on the characteristics of the angular momentum state of photon orbit, this paper studies its application and related problems in information processing and transmission. In this paper, quantum multiuser communication technology is studied, and a multiuser communication scheme based on photon orbital angular momentum state is proposed. The scheme takes advantage of the orthogonality of different orbital angular momentum states of the photon and assumes that the sender and receiver share a pair of entangled orbital angular momentum states. On this basis, the spatial light modulator is used to modulate it to the entangled photon of the sender, so that the sending photon carries all the user’s information at the same time. Finally, the receiver accurately extracts the information of each sender by measuring the coincidence count and according to the specific receiving rules. Numerical simulation and experimental results show that the coincidence rate of different coding schemes is between 0 and 0.66, which proves the feasibility of the scheme.

Choosing a career is an important choice in every student’s life, and it is particularly important to evaluate the development of vocational education for students.However, many students today do not have a clear positioning, do not know themselves clearly, do not know what their appropriate work, unable to make a suitable career development plan, thus facing greater employment pressure. Based on this, this paper introduces the development of a professional psychological assessment system for students, which can help students better understand their own interests, personality and professional ability tendency through scientific professional psychological tests, so that teachers can more accurately evaluate students’ development ability and psychology. Based on the analysis of the existing vocational assessment software, the system improves a series of defects such as inflexible report form and incomplete functional modules. In addition, the reliability and validity of the selected scale were analyzed by retest method in this paper. The Pearson plot correlation coefficient basically met the requirements of 0.6∼0.8, with an interest of 0.66, a personality of 0.71 and a personality of 0.79, indicating that the measurement content of this system has a high reliability and relevance validity.
