Abstract

Tangerang City is the largest city in Banten Province and the third largest city in Greater Jakarta area which is split by one of the major rivers on the island of Java, namely the Cisadane River. With the increasing number of population and vehicle ownership, it is necessary to develop a public transportation network to reduce traffic volume and meet the needs of urban public transportation that is fast, easy, safe and comfortable for the citizen. The existence of the Cisadane River in Tangerang City has the potential to be developed into a public transportation route in the form of a waterway. Therefore, the right strategy is needed in the planning of river transportation. This study aims to analyze the influencing factors and strategic priorities in planning river transportation as urban public transportation using the Strength Weakness Opportunity Threat (SWOT) and Analytical Hierarchy Process (AHP) methods. In this study, a questionnaire was given to eight expert respondents related to river transportation. The respondents' answers were tested for consistency with AHP to ensure the accuracy of the answers. From the results of the SWOT analysis, it was obtained the strengths, weaknesses, opportunities and threats in river transportation planning, as well as the ST (Strength-Threat) strategy with the largest weight of 3.99 as the strategy to be used in planning river transportation. Then from the AHP analysis, the strategic priority results in planning river transportation were obtained, namely the safety criteria with a weight of 0.29 and alternative strategy for life jackets with a weight of 0.117853325 as the main priority in carrying out the chosen strategy. Respondents' answers are fairly accurate with a consistency ratio of 2.58% ≤ 10%.

Abstract

The production process of making gamelan in Tihingan Village still uses the traditional way, namely using prapen with an open flame both for the melting process and in the formation process. This causes the workload of craftsmen to be quite heavy due to exposure to radiant heat and dust. The results of microclimate measurement of the work environment obtained an average dry temperature of 33.2oC, an average wet temperature of 24oC. The average ball temperature was 33oC, WBGT 26.3oC and the mean humidity (RH) was 59.0%. The average light intensity at work reaches 319.2 lux. The average temperature of the furnace at low heat is 340oC and during the combustion process it reaches 860 oC. The results of measurements of air quality in the workplace include levels of NO2 17.00 µg /m3 (increased by 112.50%), SO2 5.33 µg/m3 (increased by 45.23%), CO 407.16 µg/m3 (increased by 217, 99%), oxidants (Ox) 61.00 µg/m3 (increased by 1.67%) and dust 48.50 µg/m3 (increased by 125.58%). The mean pulse of the nguwad workers reached 125.81±1.35 beats/minutes (including heavy workload). This causes the productivity of craftsmen to be low due to the increase in musculoskeletal disorders and craftsmen fatigue. To overcome this condition, the workings of the craftsmen need to be improved immediately through the application of appropriate technology in the form of furnace repair so that the flames and dust produced can be removed from the workplace, then exposure to hot air and combustion dust will no longer expose the craftsmen.

Abstract

Less optimized natural lighting would result in apartment residents being dependent on artificial lighting, thus increasing energy consumption. Building opening orientation considerably influences the natural light intensity. This research aimed to analyze the natural lighting pattern on apartment units with east-oriented opening orientation and determine methods to support the existing condition to be optimized. This research applied the descriptive analysis research method assumed from calculation outcome of the software DIALux. Results indicated a proportion of units in The H-Residence Apartment do not meet the requirements specified by SNI 03 6197-2011, predominantly in the kitchen area. The average light intensity in a day in units with east-oriented opening reached its peak at 08.00 – 09.00 a.m. and decreased towards 16.00 p.m. following the sun path. The light intensity in numerous areas exceeded the requirements significantly. Other factors influencing the natural light distribution are layout and interior element. Several ways to optimize the natural light intensity utilization are adding suitable shading device, using dark-colored interior elements, and considering the sun path in designing building openings.

Abstract

The process of drying fish using solar energy is strongly influenced by weather conditions. Sunlight is needed by household scale workers because it is cheap. On the other hand, sun drying creates additional workload for workers. Workers are exposed to hot sun during drying. Continuous heat exposure results in an increased work pulse. This affects the level of worker productivity. To anticipate this, a solar dryer is used by utilizing a solar collector as an absorber of sunlight and a drying chamber for the drying process of fish. The use of solar dryers has been shown to increase drying temperatures and reduce workers' sun exposure. This decreases the workload of workers, so that it has an impact on increasing productivity. Worker productivity increased by 133.94%.

Abstract

In the construction planning process, the calculation of the quantity of each project work was packaged in a Bill of Quantity (BoQ) to complete the project and greatly affected the continuity of the entire construction construction process. With advances in technology in the world of construction, it could simplify planning in built a building and could increased the accuracy of calculations without using assumptions that could increased the volume of work. One of the results of current technological advances was the creation of the Building Information Modeling (BIM) method, a method that was able to simulate all information in a development project into a 3-dimensional model. Currently the use of the BIM method in Indonesia was still limited so that in this research, the aim was to determine the effectiveness of the use of BIM on the accuracy calculation of the volume of the BoQ and to know the percentage comparison. The building project that was used as a comparison was a building with the middle rise building category, namely the Central Jakarta BPJS Building. Based on the research conducted, it was found that the difference between conventional and BIM results on pilecap components was 5%, column 6%, beam 35%, floor slabs 2%, stairs 22%, ceiling 2.26% floor coverings 14% lower than conventional calculations but for the wall component the BIM calculation is 0.78% greater than the conventional calculation. So that the total percentage ratio is 10%, thus this proves that the use of the BIM method in calculating quantity was effective in terms of calculation accuracy.

Abstract

This paper deals with a comparison of inverter types and develops a system to provide pure sine wave ac voltage. The ac voltage is utilized to drive the compressor ac split. The assembled inverter problem is a square waveform, power losses, torque, efficiency, and a lag behind in terms of performance reliability. The push-pull amplifiers technic is proposed to produce sine wave output from dc input. The output result shows that an experimental pure sin wave obtains a frequency of 50.05 Hz, V max 13.49 Volt, V min -14.49 volt, and duty cycle 50.1%. the assembled inverter has a frequency is 37.87 Hz, V max 11.88 Volt, V min 13.09 volt, and a duty cycle is 50 %. A modified 3-phase inverter attains frequency 50.05 Hz, V max 15.71 Volt, V min -16.11 Volt, and the duty cycle is 50.5 %. The frequency, v max, v min, and duty cycle are bigger than an assembled inverter, then the modified 3-phase inverter has small harmonic distortion. The comparison of inverter types gives information for home appliances.

Abstract

When the box culvert system is placed on a sandy soil layer with a relatively low bearing capacity and is disposed to potential liquefaction, the soil layer must be repaired to avoid damages to the box culvert structure. The proposed method is Geosynthetic Encased Stone Columns (GESC) to increase the bearing capacity and anticipated the liquefaction potential. however, to meet the criteria for a stable and safe GESC soil improvement in liquefaction conditions, the value of the settlement must meet the requirements for the settlement permit limit. This research was conducted to determine the potential for liquefaction at the study location, to calculate the value of single and group settlements in liquefaction conditions and to analyze the stability of single and group settlements including safe or unsafe in liquefaction conditions. Analysis of liquefaction potential was analyzed based on SPT data using the Valera and Donovan method, and settlement analysis applied the Almeida and Alexiew method. The analysis shows that potential liquefaction due to an earthquake with a magnitude of 9.0 SR will be at a depth of 4 to 8 m. Single and group settlements (144 sets) with an installation distance of 1.2 m with a diameter of 0.4 m and at a depth of 10 m are 246.23 and 214.92 mm, respectively. The entire GESC system is considered to be in an unstable and unsafe condition against potential liquefaction and box culvert loading.
