Published: July 2020

At present, the adsorbents generally use bentonite and activated carbon, but the availability of bentonite is less so that other alternatives are needed for substitution of bentonite as an adsorbent. One of the materials that have the potential as an adsorbent is the ceramic industry waste (ceramic clay). Ceramics clay containing feldspar which before being activated using sulfuric acid has a ratio of concentration between silica and alumina (silica/alumina) of 3.6, so a process is needed to increase the ratio of silica and alumina. One such process is by activating ceramic clay using sulfuric acid. The characterization and adsorption performance of adsorbent from ceramic clay were studied with various acid concentration. Ceramic clay powder was activated with sulfuric acid. The adsorbent particles were characterized by IR Spectra, X-Ray Diffraction, X-Ray Fluorescence, and BET. Various concentrations of sulfuric acid solutions for activation have a significant effect on the characteristics and performance adsorbent. This is indicated by XRD analysis where the characteristics of the adsorbent have feldspar (Ca-KAl2SiO3) content with the ratio between silica and alumina increasing around 4.3-4.8 with an increase in sulfuric acid concentration from 10-30% and adsorbents in the form of mesoporous crystalline structure. The characteristics of adsorbent with IR Spectra analysis showed that the presence of silicate alumina groups, so the products have the potential as a bleaching agent. The best surface area is produced at a concentration of 15 % sulfuric acid solution with one hour activation time which is equal to 117.44 m2/g.

A company needs to improve its performance, especially in terms of quality, in an effort to assure its survival in the business competition with other companies. Therefore, the company needs to measure its performance so that it can find out its current position in the competition and how to improve said position and achieve its goals. Nowadays, many companies try to improve themselves by putting more emphasis on product quality, which is an external kind of quality, instead of on the internal quality of the company. This strategy will not yield the best result in the long run because the internal quality affect the quality of the resulting products. One of management systems that put emphasis on the internal quality and consumer satisfaction is Total Quality Management, which involves all members of the organization. One approach to the aspects included in Total Quality Management is to use the Deming Prize, which reviews the internal quality based on several categories. Based on the results and data analysis, it can be seen that the score for organizational variables is 3.41; standardization of 3.00; control of 2.81; analysis of 2.59; and influence of 3.30. However, there are several categories in the variable that are lower than the terget score, among others, job analysis, organizational goals, work tools, measurement, employee input, and rewards.

Published: July 2020

This paper presents field analyses on the influences of condenser and evaporator approach temperatures of water cooled air conditioning system for a shopping mall. The mall building comprises food and non-food retail stores and uses a centralized air conditioning (AC) system to condition the entire building. The AC system comprises three chillers with the same cooling capacity. Chillers’ performance parameters included power consumption, condensing and evaporating temperatures, evaporator-condenser approach temperatures, pressure drop and cooling capacity parameters were hourly recorded for a period of one year. Performance characteristics of each chiller were evaluated at different condenser and evaporator approach temperatures and regression analyses were also established to examine the correlations and influences of the approach temperatures on the chillers’ performance. The analyses results showed that the increase of condenser approach temperature could increase the power consumption and reduce the coefficient of performance (COP) of the chillers. While evaporator approach temperature was found to have insignificant effect to the chiller performance. The results also showed that for the investigated chillers with condenser and evaporator approach temperatures maintained below 2 K, the approach temperatures had negligible correlation to the power consumption and the overall performance of the chillers. At this operational conditions, the water cooled air conditioning systems could operate at their best possible performance.

Lung is one of the vital respiratory organs in the human body. Where during respiration, there is a process of gas exchange in the lungs by taking oxygen (O2) from the air and releasing carbon dioxide (CO2) into the air. Because in the process of respiration involves air in the surrounding environment, the more contamination of air is inhaled, can cause various lung diseases. If the lung diagnosis is done early, then lung disease can get health care earlier. Chronic Obstructive Pulmonary Disease (COPD) is a type of disease that blocks the flow of air into the lungs due to swelling and mucus or phlegm, so that the sufferer has difficulty breathing. In making this research, we want to make a design tool to detect COPD and determine its severity using medspiro (medical spirometer). COPD can be diagnosed by measuring the value of Forced Expiratory Volume in One Second (FEV1), Forced Vital Capacity (FVC) and comparing it with predictive values of FVC and FEV1. The results obtained from the manufacture of spirometers have FVC measurement errors of 5.8950%, and FEV1 measurement errors of 10.5030%.

Published: July 2020

Humans often encounter obstacles in doing their work. Especially if the work is related to an emergency situation that concerns the safety of human life, it needs quick and appropriate handling. Telerobotic technology that has a haptic function is one solution to these problems. In this study a system of 1 DOF haptic manipulator with slave master configuration was developed using bilateral haptic manipulator control. In bilateral control the position and information are transmitted in two directions between two manipulators. Position information is obtained using a potentiometer and force information is obtained by representing the force with the current using the WCS2702 sensor. There are three control methods used, namely bilateral symmetrical position control, bilateral reflection force control and force feedback bilateral control. The best method of control is the bilateral feedback force control. In the force feedback bilateral control system, the slave can move following the master movement with a ± 2° position error. When the slave arm is held by a hard object, the master arm is also restrained with ± 11° position error. Whereas when the slave arm is held by a soft object, the reflection of the object is felt by the master arm with ± 10 position error. Movement of the master and slave arms is lighter than using bilateral control of symmetrical position.

Walking is a non-motorized transportation option that has a large portion compared to the use of bicycles and traditional transportation. Previously, the quality assessment of pedestrians was only calculated based on their physical form. But now the pedestrian ways are not only seen as a facility to support the human movement but has become a public space. To investigate this, we surveyed Pahlawan Street, Semarang, Indonesia (N=90). The method using is PEQI (Pedestrian Environment Quality Index) which is a quantitative calculation based on the 5 indicators (crosswalk safety, pedestrian traffic, land use, street design, perceived walkability). We find that the most qualified pedestrian way is Segment I East (70.35), though the lowest is Segment III East (50.16). In particular, we find that the percentage of social and optional activity is higher than the necessary activity that been the user choose in Pahlawan Street.

The building price is especially fluctuating every year. The price fluctuations can be caused by several factors, both in terms of material costs and in terms of labor costs. There are several studies discuss the prediction of the budget plan, but not to discuss the most influential cost components in increasing the cost of building a residential house. so that it is not known what costs need to get special attention to be made savings, from this it is necessary to do this research so that the estimator can focus on the largest cost component for alternative swatches so that cost savings can be made. The method used is the method of quantity take-off. As a result, the average salary and material needs for housing are 31% for salaries, while for materials it is 69% of the total cost. The highest order is for the salaries of the first workers, second handyman, third foreman and the last is the chief handyman. Whereas in the most influential cost material is portland cement, both concrete iron, third galvalume frame, and finally aluminum. These prices and salaries need to be considered to make savings in the planned budget for a residential house.

Commonly house’s damage under earthquake is because their capacity inadequate to prevent from collapse, and the masonry wall system is not designed to resist the earthquake force. However, masonry infill wall is commonly used as partition and to separate large area with a purposed. Interaction between frame and masonry infill wall are not good connected to prevent building damage from earthquake. To understand the interaction between frames and infill wall can be simulated by numerical method or by Macro-modelling approach. The purpose of this numerical study is modelled a frame as a single element, a masonry infill wall as a plate element, and an interface between frame and masonry infill wall as an elastic spring. The concept of modelling depends on material parametric provided and the number of elements. Modelling with computational software facilitate to create material element and model and this modelling is conducted by Tohoku-coast NS time history seismic. The result shows the frequency parameter expressively increase from frequency on frame model to frame with infill wall model, or the time period parameter significantly reduce with the addition of infill wall. By the addition of mortar thickness which increased the stiffness also affect the frequency parameter and maximum displacement. The thickness of mortar brought the optimal value to good response is recommended with thickness of 0.5 cm to 1.5 cm. The finding is that infill wall gives significant influence on frame response if the interface of frame and infill wall designed with good material characters.

In Indonesia, as part of tropical regions, calculating the amount of daily potential evapotranspiration (PET) becomes significant to ascertain the water balance. Applied Artificial Neural Network (ANN) as data-driven modeling in the period of Industrial Revolution 4.0 to develop a better world. Using ANN simplifies the process of modeling the various input climate data to count up the amount of daily PET. There six climate data that will be input in the Modified Penman Method, which are average-temperature, wind velocity, rainfall, relative-humidity, evaporation, and the time of solar radiation. Therefore, for further modeling using fewer input data than typically used in this method, so the high affect climatology data must be known. The methodology is to compare the best model, which has input six of the climate data with the model developed by just five of the climate data. The results of this research are the sequence of climate data that influence the daily PET model from the highest to the smallest: wind velocity, relative humidity, the time of solar radiation, temperature, rainfall, evaporation.
