Penentuan Rute Tercepat Pemadam Kebakaran di Kota Cirebon - Berdasarkan Jarak, Waktu Kejadian, Tingkat Kemacetan dan Jenis Penggunaan Lahan
Get PDFKinerja pemadam kebakaran dapat direpresetasikan dengan kecepatan penanganan pada saat terjadi kasus kebakaran, dimana kecepatan penanganan sangat dipengaruhi oleh kecepatan tempuh unit pemadam kebakaran menuju lokasi kebakaran. Penelitian ini bertujuan untuk mengetahui rute tercepat bagi unit pemadam kebakaran di Kota Cirebon berdasarkan jarak tempuh, waktu kejadian, tingkat kemacetan dan jenis penggunaan lahan. Metode yang dilakukan dalam penelitian ini yaitu dengan cara menerapkan model Geographic Information System (GIS) dalam mengidentifikasi beberapa variable yang mempengaruhi kecepatan tempuh unit pemadam kebakaran. Pada penelitian ini ditentukan beberapa alternatif rute dari pos pemadam kebakaran (Pos Damkar Harjamukti dan Pos Damkar Bima) menuju objek lokasi kebakaran (Pasar Harjamukti) kemudian dihitung waktu tempuh pada masing-masing alternatif rute dengan mempertimbangkan variable jarak tempuh, waktu kejadian, tingkat kemacetan dan jenis penggunaan lahannya. Hasil penelitian diperoleh bahwa waktu tempuh tercepat kendaraan pemadam kebakaran di Kota Cirebon sebagian besar dipengaruhi oleh jarak tempuhnya. Akan tetapi pada kondisi arus lalu lintas tinggi, rute dengan jarak yang lebih panjang tetapi tidak melintasi ruas jalan yang macet dapat menghasilkan waktu tempuh yang lebih cepat jika dibandingkan dengan rute yang lebih pendek tetapi melintasi ruas jalan yang macet. Rute tercepat dari pos pemadam kebakaran Bima menuju Pasar harjamukti adalah rute 1 (2.854 m) pada pagi hari, rute 3 (3.019 m) pada siang dan sore hari. Sedangkan rute tercepat dari pos pemadam kebakaran Harjamukti menuju Pasar harjamukti adalah rute 1 (2.069 m) baik pada pagi, siang maupun sore hari karena memiliki jarak terpendek

Design of Fault Tolerant Control on Wind Turbine Speed Control Based on Bias Fault Estimation Method with Optimization l_0 Norm Constraint
No full textThe availability of onshore wind power plant systems (PLTB) reaches 98%, but the maintenance costs required are still very high for the wind turbine generator system. Meanwhile, the availability of offshore PLTB is decreased by 60% due to the main cause of damage to some components in wind turbine systems. This study proposes the use of fault estimation methods of wind turbine system components in fault tolerant control (FTC) strategy. The error estimation method is build using the ℓ0 norm constraint optimization. The optimization formulation with ℓ0 norm constraint is derived by applying the compressed sensing technique so that the estimation of the bias error can be used to estimate the error of several components by a single observer. This answers the observability issues encountered in single observer use cases. The proposed implementation of observers with the FTC results in better response characteristics when compared to systems without FTC. Response characteristics on actuator errors of 0.3 – 1.3pu, system with observers resulting in a maximum undershoot value of 0.4-1% while systems without observers resulting in a maximum undershoot value of 6.2-26.4%. The characteristics of the response with the observer on sensor errors resulting 0.3-1.3pu resulting in value of 1.6-4%, 0% and 63.9- 70.7s. System without observers, with sensor errors of 0.3-1.3pu resulting in maximum undershoot, steady state error and settling time of 6.2-26.2%, 6.2-26.4%, and 0
Servant Leader’s Characteristics: Implications for Youth Christian Leaders in FS Community
Get PDFThe world knows many types of leadership, one of which is servant leadership pioneered by Greenleaf (1977). According to Spears (2010), servant leadership has 10 main characteristics that make it unique. These characteristics enable a leader to focus on his/her followers and strive to make them grow better, unlike other leadership styles that focus on organizational interests and goals (Rachmawati and Lantu, 2014). This practice of servant leadership started by Jesus Christ continues to be emulated and lived by many figures after Him. Unfortunately, not all people who claim to be Christians (followers of Christ) actually become servant leaders. This study aims to explore whether the main characteristics of servant leadership really emerge in leaders and still relevant to be practiced in church life today. We will focus on exploring servant leadership practices at FS Community, the youth community of GKA Gloria Pacar, using observation, interview, and document analysis. The ten characteristics that discussed in this research are listening, empathy, healing, awareness, persuasion, conceptualization, foresight, stewardship, commitment to the growth of people, and building community. These are not a requirement that all must be prominent in each leader, but rather are the traits of servant leaders. It means, the more these characters are seen in a person, the more he/she has a heart that is willing to serve, and the closer he/she is to the picture of a perfect servant leader. Although perfection is not possible because we are only limited human beings, these ten characters must be a dream to be pursued by leaders who claim themselves as servant leaders

The Use of PT Petro Kimia’s by-Product Gypsum as Fill Materials
Get PDFGypsum is a by-product of the Phosphoric Acid factory PT Gresik Petrochemicals; it is produced around 1,200,000 tons/year. In order to reduce the amount, an effort needed to use gypsum as fill materials. For this purpose, the problem needs to be considered is that gypsum should not contain substances that harmful to the environment and meet the fill materials requirements. In order to answer all these questions, chemical tests were carried out to determine its heavy metal content. Gypsum plasticity and its particle size distribution were determined by conducting Atterberg limit and sieve analysis tests. Compaction test and CBR test were also carried out to determine the density and its strength. Those results were then analyzed using "The Fifteen Point Method" to obtain a relationship curve between dry density (d) and soaked-CBR. This curve was important to determine the soaked-CBR that can be achieved by gypsum materials in the field with different compaction energy 90%, 95%, and 100% of maximum compaction energy. Chemical test result shows that all heavy metals content in gypsum material are far below the regulatory limit; therefore, it is safe for the environment. Besides, Gypsum is non-plastic (NP) material and it is classified as A-4 (AASHTO) or SM (USCS); it means that Gypsum is very good for fill materials and safe to the environment. In addition, the result from the Fifteen Point Method shows that the minimum soaked CBR value is 13% achieved by using 90% of maximum compaction energy with 30-40 % of water content. It means that the gypsum material can be used as selected fill material because it fulfils its requirement where IP10%

Performance Analysis of Screw Turbine Design with Additional Flaps Modification Using Computational Fluid Dynamics Method
Get PDFRenewable energy is a type of alternative energy that can be utilized to generate electricity. Wind energy is one of the renewable energy sources. Because of Indonesia's equatorial location, the wind characteristics are moderate, with wind direction and speed changing frequently. To harvest wind energy, it is therefore vital to diversify the types of wind turbines. A screw turbine, also known as an Archimedes screw turbine or a screw turbine, is a type of wind turbine that is often employed in micro hydropower plants. The great efficiency of this turbine is a benefit. This screw turbine will use a Horizontal Axis Wind Turbine (HAWT). The advantage of using the horizontal axis over the vertical axis is that the rotor's efficiency is higher. The screw turbine was changed in this study by adding flaps to boost torque and rpm performance while also increasing wind catchment. The model design with the inclusion of 3 cm flaps with a flap angle of 30° has a high torque and angular velocity with a torque value of 0.00609 Nm and an angular velocity of 12.55 rad/s at an airflow velocity of 3.4 m/s, according to the results obtained from model simulation using CFD (119,84 RPM). Power Coefficient (CP) = 0.00659, Torque Coefficient (CQ) = 0.01990, and Tip Speed Ratio (TSR) = 0.331357
