On the other hand, a new project can make construction service<br>businesses have problems due to their failure to manage existing resources. One of the risks is the delay in project<br>completion time, which results in the threat of penalty by the construction project owner. This study aims to reduce<br>the risk of penalties faced by small-scale construction service businesses using Time cost trade-off (TCTO). TCTO<br>is a method used to increase the productivity of human resources by substitute using several costs. In increasing<br>the productivity of human resources, this study uses two work systems, namely a four-hour overtime system and<br>a Shift work system. The results of this study found that by using shift work system, it can accelerate the project<br>complementation time by 70 days and reduce the risk of penalties by Rp. 2,525,634,233.<br><br>ABSTRAK<br>Industri konstruksi di Indonesia yang berkembang cukup baik, membuat pelaku usaha jasa konstruksi skala kecil<br>mendapatkan banyak peluang proyek baru. Disisi lain proyek baru dapat membuat pelaku usaha jasa konstruksi<br>mengalami masalah dikarenakan kegagalan mereka dalam mengelola sumber daya yang ada. Salah satu risiko<br>yang terjadi akibat kegagalan mengelola sumber daya adalah keterlambatan waktu penyelesaian proyek yang<br>berakibat pada ancaman penalti oleh pihak pemilik pengguna jasa konstruksi. Penelitian ini bertujuan untuk<br>mengurangi risiko penalti yang dihadapi pelaku usaha jasa konstruksi skala kecil dengan cara Timecosttardeoff<br>(TCTO). TCTO adalah sebuah metode yang digunakan untuk meningkatkan kapasitas produktivitas sumber daya<br>manusia dengan menggantinya menggunakan sejumlah biaya. Dalam menaikkan produktivitas sumber daya<br>manusia, penelitian ini menggunakan dua sistem kerja yaitu sistem kerja lembur selama empat jam dan sistem<br>kerja Shift. Hasil dari penelitian ini didapatkan bahwa dengan menaikkan produktivitas kerja dengan sistem shift<br>dapat mempercepat waktu pelaksanaan sampai dengan 70 hari dan mengurangi risiko denda sebesar Rp.<br>2.525.634.233</p> Felicia T.

Sidewalks are a means of transportation for pedestrians to indulge. However, in Blitar City such as Jl. Ahmad Yani is still improving the two terms in terms of physical as well as in terms of utilization. There are still many groups that approve the sidewalk, there is also damage to the sidewalk that makes pedestrians feel uncomfortable for activities. Method of collecting data. Questionnaires and documentation are needed. Analysis of the data used is quantitative data. Data processing using SPSS version 20. The results obtained, the level of comfort (43.95%), safety (52.3%), and security (51.4%) can be categorized quite well.</p> Putri Copyright (c) 2019 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2019-11-06 2019-11-06 9 2 12 19 10.35457/quateknika.v9i2.823 EVALUASI KINERJA PELAYANAN ANGKUTAN UMUM BERUPA BUS BAGONG https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/824 <p>The title of this thesis is “Performance Evaluation of Public Transport Service in the Form of Bagong Buses”. Bus is one of the public transportation that is needed by the community to support their activities. However, there are still many buses that operate in an unfit condition (age and condition of the vehicle). In addition, bus cleanliness also affects passenger comfort. In this study, researchers took the Bagong Bus sample. Data collection methods include questionnaires and documentation. Analysis of the data used is quantitative data. Data processing using SPSS version 20. The results obtained, the level of comfort (80.95%), cleanliness (94.44%), and service (66.67%) can be categorized quite well</p> Fandre Copyright (c) 2019 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2019-09-23 2019-09-23 9 2 20 26 10.35457/quateknika.v9i2.824 REAL TIME CLOCK SEBAGAI TRACKING SINAR MATAHARI PADA SOLAR CELL BERBASIS MIKROKONTROLER UNTUK LAMPU TAMA https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/821 <p>One of the new and renewable energy is the utilization of sunlight into electricity. which can be used to be converted into electrical energy using solar panels. The installation of solar panels installed for garden lights so far is often still placed in a static (silent) position at an angle of 90⁰, while the sun moves from sunrise to sunset. Because it will cause maximum energy absorption in solar panels which are placed in a static position only at 12:00. To overcome this problem a system is needed to track the position of the sun so that it is always perpendicular to the surface of the solar panel. Design and build garden lights with a solar light tracking system on a microcontroller-based solar panel will later be made to move because it follows the direction of the sun's movement every hour, from rising to setting. This tool will detect the time setting inputted by Real Time Clock (RTC) which is then processed by a microcontroller to drive a servo motor that functions as a solar panel drive machine so that the position of the solar panel will always be perpendicular to the sun. throughout the day and the absorption of energy in solar panels will be more leverage. From the results of tests that have been done, the increase in the voltage of solar panels using a tracking system compared to solar panels without using a tracking system is 7.85%.</p> Moch Nur Qomaruddin(1), Matlubul Khairi(2), Sulistiyanto Copyright (c) 2019 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2019-09-23 2019-09-23 9 2 27 32 10.35457/quateknika.v9i2.821 APLIKASI DANGER MESSAGE DAERAH RAWAN KECELAKAAN DENGAN ANDROID GIS https://ejournal.unisbablitar.ac.id/index.php/qua/article/view/822 <p>There are several areas in Probolinggo District where accidents often occur because the location of the existing road is indeed very dangerous, because of sharp turns or because of the heavy traffic on the road, this problem can be reduced by giving messages through the Android mobile application. The number of accidents that occur in various places with the time of the incident in the district of Probolinggo can be obtained at the Office of Transportation. The purpose of this research is to create an GIS android application that can provide information about maps of accident-prone areas in Probolinggo Regency. The method used is using a spiral. With stages, Planning, Risk Analysis, Product Engineering, Evaluation by users. Information about traffic accident-prone locations is very much needed by the community, transportation and law enforcement agencies in this case the police. Android-based Geographic Information System as an appropriate tool to be applied in this case because it uses the Mapping location of accident-prone areas and will, sending messages (dangger message), in the form of user distance from accident-prone locations.</p> Ranu Setyobudi(1), Matlubul Khairi(2), Sulistiyanto(3) Copyright (c) 2019 Jurnal Qua Teknika https://creativecommons.org/licenses/by-sa/4.0 2019-09-23 2019-09-23 9 2 33 37 10.35457/quateknika.v9i2.822
