Abstract

Every construction project, whether high-tech or simple, has risks in the implementation process. there-fore it is necessary to establish a Project Safety Management (PSM), to minimize the risk of occupational safety and health (OSH) of construction project. However there are still many construction companies that are lacking in identifying risks of occupational safety and health(OSH) of construction project and implementing an occupational Project Safety Management (PSM)) in the process of implementing a con-struction project. The purpose of this study was to determine the level of risk occupational safety and health based on existing risk factors, and to measure the application level of SMK3 in a construction pro-ject. In this study, the object of the case study was the construction project of the Mangusada Badung Regional General Hospital, at the time of finishing work. After carrying out risk identification, 4 risk fac-tors are obtained, namely human, material, equipment and environmental factors. then the results of the identification are processed, and the level of risk obtained from the implementa-tion of the Mangusada Badung Regional General Hospital Development Project is included in the Medium Category, with a risk value of 6. Meanwhile, the implementation of the Project Safety Management (PSM) of the Mangusada Badung Regional General Hospital Construction Project was included in the good cate-gory with a total application value of 83%. Hopefully this research will serve as a reference in identifying occupational safety and health (OSH) risks, and a reference in implementing the Occupational Project Sfety Manajemen (PSM).

Abstract

Compost is an important organic fertilizer in agriculture. Compost comes from weathering / decomposition of waste such as leaves. In the composting process, it can occur naturally but requires a longer time because during the decomposition process the temperature can change so that the performance of microorganisms that decompose waste decreases. The Arduino-based automatic machine is designed to maintain the temperature during the composting process. There are two types of systems used in composting machines. The first composting machine uses an automatic system that works every 3 hours to stir the waste in the tube while the second machine uses the system to work when the temperature detected by the DS18b20 sensor in the tube increases. In the second engine system the highest temperature is set at 38˚C. If the temperature in the tube increases and exceeds the temperature limit that has been set, the motor will work to stir the waste until the temperature in the tube drops. The results of the compost feasibility test on the first machine obtained a pH value of 5.84; Nitrogen 9.67%; Organic carbon 16.33%; C/N ratio 16.90; while the second machine obtained a pH value of 5.60; 8.60% Nitrogen; 17.89% organic carbon; C/N ratio 20.81

Abstract

In this study, the focus is on the analysis of oil quality pollution caused by the thirst of the components in the engine. [7]Komponen bagian dalam engine yang dialiri oleh pelumas sangat berpotensi terjadinya kehausan yang diakibatkan oleh pergesekkan antara material yang beroperasi dalam sistem kerja engine. Oil in the engine has specifications or properties that will affect engine performance. In this study, the authors took samples on the diesel engine oil multi grade S.A.E 15W-40 which was applied to an excavator heavy equipment engine with a capacity of eleven tons. One type of Additives in engine oil is Anti-Wear which functions to reduce wear by coating the surface with an oil film. The focus of this research will be to see how much thirst occurs in the internal components of the engine that are flowing with oil. The thirst of components in the engine will be seen from the quality of the engine oil, if the thirst that occurs is greater then the work of anti-wear additives in the oil has begun to decrease so there must be a solution or analysis obtained. Test results on tests from the S.O.S. laboratory From the six sampling times, the highest wear metal value was 35 ppm at the time of operation of the 1665 Meter [Hr] unit. Based on the results of the test, it is stated that the excavator engine is in good condition when viewed from the wear metal, oil contaminant, oil condition and oil viscosity.

Abstract

Repeated heating of paml oil has a greater effect to produce high levels of trans fat. The excess consumsion of food contained trans fat is couse of diabetes and coronary heart diseas. The oil spinner machine of 10 kg capacity are proposed to overide this problem because it is able to throw the oil particles out from the fried food caused by centrifugal force. The drying area is a 50 cm long tube having diameter of 40 cm which is driven by an electric motor single-phase 1 Hp 1400 rpm. In order to increase the speed of the drying tube into 2800 rpm, a 6 inch diameter pulley attached to the motor shaft while a 3 inch is mounted on a 10 cm diameter drying tube shaft. The two pulleys are connected by means of an open belt drive with a length of 60 inch and 187,480 the contact angle.

Abstract

Fiber To The Home (FTTH) is a network that uses fiber optics. One of the devices on FTTH is optical distribution point (ODP). There are two methods of ODP installation, namely by connecting aerial cables directly to ODP and branching. Branching is a method of branching FTTH devices. In previous studies branching was carried out in the closure. However, in the study there was a drawback, namely the branching in the closure must be carried out by connecting fiber optic cables which requires high accuracy. Therefore, this study discusses branching in ODP with the 1: 2 passive splitter method and dropcore cable. Therefore, with this method branching can be done without connecting fiber optic cables. The result of this study is branching with a 1:2 passive splitter, one of the outputs to the ODP Closure Area of the passive splitter 1:8 has a high attenuation value when at the customer's home, which is 32.23dB, compared to other outputs in the passive splitter 1:2 directly connected to the OTB has a attenuation value of 23.53dB. In contrast to branching, using a dropcore cable to the ODP passive splitter 1:4 as a branching tool produces a attenuation value of 26.55dB, which is in accordance with the standards for all four outputs. The high attenuation value affects the quality of the network in the customer's home. Therefore, good branching is to use a dropcore cable. The allowable attenuation value in the customer's home is less than 28dB in accordance with itu-T G.984 standard.

Abstract

In this study, a comparison was made of the attenuation values ​​of passive splitters 1:8 and 1:16 in Optical Distribution Points (ODP). Perform several measurements at the ODP using an Optical Light Source paired with a Passive Splitter 1:4 and 1:8 to become input power at the Optical Distribution Cabinet (ODC) and measure the output from the Passive Splitter 1:8 and Passive Splitter 1:16 at the ODP using Optical Power Meter (OPM) as a measuring tool with a cable length parameter of 100 meters. The measurement results using the OPM are smaller than the calculations with the Power Link Budget, with the measurement results of the passive splitter 1:8 on ODP with measurements made at the rosette obtained attenuation of -19.78 dBm and the results of measurements on passive splitter 1:16 on ODP with measurements carried out in the rosette the attenuation is -23.57, from these results it can be said that the use of passive splitters with excess needs can be used with replacement of passive splitters that have more capacity.

Abstract

Seiring dengan perkembangan ilmu pengetahuan dan teknologi, campuran beton mengalami beberapa perubahan seperti dengan diberi material tambahan atau penggantian suatu bahan dalam beton untuk memenuhi tujuan tertentu. hal tersebut dapat memberikan alternatif untuk memanfaatkan limbah plastik yang tidak termanfaatkan sehingga diharapkan mampu mengurangi pencemaran lingkungan yang terjadi dan dapat menaikkan kualitas beton yang lebih tahan terhadap retakan. Metoda perencanaan campuran beton menggunakan metoda American Concrete Institute (ACI) 112.4R 1993 dengan variasi penambahan cacahan limbah plastik HDPE terhadap agregat halus tertahan saringan 2.36 mm sebesar 0.5%, 1.5%, dan 2.5%. Berdasarkan data hasil pengujian kuat lentur beton umur 56 hari dapat diketahuibahwa kuat lentur beton umur 56 hari mengalami penurunan 9.672% pada variasi 0.5%, dan 27.204% pada variasi 1.5% terhadap nilai kuat lentur tanpa tambahan limbah plastik. Penggunaan plastik dengan variasi 0.5%, dan 1.5% pada beton belum mampu menahan retak akibat beban tarikan pada saat pengujian lentur. Sedangkan padapengujain pola retak pada benda uji dapat disimpulkan bahwa setiap pertambahan variasi cacahan plastik pada beton mempengaruhi pola retak yang dihasilkan dimana pola retak yang dihasilakan semakin memanjang.

Abstract

Population growth that continues to increase and the ease of purchasing private cars is one factor in the increase in the number of private car owners. The government is here to change public transport services in the regions, including by operating the Trans Metro Dewata Bus in four corridors within the Sarbagita area. For now, the amount of vehicle operating costs (BOK) and operating income obtained from the operation of the Trans Metro Dewata Bus are unknown. This needs to be investigated further, especially in terms of financial feasibility. Based on the results of the study, assuming the bus fleet from the government, the total operational costs of Trans Metro Dewata Bus vehicles from 2023 - 2029, amounting to Rp.282,256,543,602. Assuming the bus fleet from the operator, the total operational cost of Trans Metro Dewata Bus vehicles from 2023 – 2029 is Rp. 391,744,920,721. The operating income based on the buy the service scheme from 2023-2029 is Rp. 366,173,491,600, while operating income based on the Tariff of Governor Regulation No. 112 of 2018 from 2023-2029 is Rp. 67,495,948,574. Based on the tariff according to Governor Regulation No. 112 of 2018 the operation of the Trans Metro Dewata Bus is not financially feasible.
