Abstract

The aim of this research is to optimise the utilization of third runway in Soekarno Hatta International Airport by giving recommendation based on calculation and simulation of runway capacity. The flight schedule data in Soekarno-Hatta International Airport was taken from flightradar24.com for duration of 1- 6 January 2020. The calculation of the runway capacity uses time space analysis method and simulation in BlueSky ATM Simulator. The highest runway capacity of 44 flights per hour is reached when the runway operates as take-off only or landing-only configuration. The simulation is conducted for 3 scenarios: 2 runways configuration, 3 runways configuration and 3 runways configuration with modification. The log data of simulation is analysed using Python programming to know the separation for every pair of flights and ensured that the minima distance due to wake turbulence is fulfilled. The recommendations are runway 07L/25R and 06/24 operates as segregated parallel operation by installing ILS on runway 06/24, extending NP2 and NP3 taxiway for increasing the capacity and reducing the runway incident probability. The results from extending the taxiway are the operation of runway 06/24 will not disturb runway 07L/25R operation, the runway capacity will increase by 60%, and the utilization of third runway will increase by 55%.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dari refiner time (waktu penggilingan ulang) terhadap kualitas tissue.Data yang dikumpulkan adalah data primer saat proses pembuatan tissue (handsheet).Waktu untuk LBKP (5,  10 dan 25) menit dan NBKP (10, 30 dan 40) menit. Masing-masing pulp dibuat sebanyak 2 buah. Kemudian dilakukan pengujian di Laboratorium QC dengan faktor pengujian yang menentukan kualitas tissue. Seperti:freeness(derajat giling), thickness(ketebalan), machine direction tensile(kekuatan), basisweight (berat), elongation (daya mulur) dan porosity(kerapatan serat). Hasil yang didapat jika semakin lama refiner time,maka (1) freeness akan semakin rendah, (2) thickness akan semakin tinggi, (3) measure direction tensile akan semakin tinggi, (4)elongation akan semakin tinggi dan (5) porosity akan semakin tinggi. Namun tidak akan memengaruhi nilai dari basis weight.

Abstract

Flight planning is one of the essential factors of the airline operation. The selection of routes will determine the economic value of the flight. However, some conditions may prevent the flight to use the most optimum route due to airspace restriction or weather condition. The research aims to develop a search engine program that uses dynamic flight parameters that considers fusion of System Wide Information Management (SWIM) data including weather data and NOTAM to produce the most optimum route in 2D flight planning. The Dijkstra’s pathfinding is implemented in Python programming language to produce the flight plan. The navigation data used is enroute airway in Indonesian FIR regions. The scenario used is a flight from Jakarta to Makassar with duration of 2 hours flight with considering the effect of restricted airspace and weather blockage during in-flight. The study also uses the optimum route produced by the algorithm to be compared with the possible alternate routes to define how optimum the route is. Adding a restricted airspace parameter will result in a new optimum flight plan that able avoids the airspace and the most minimum distance. The effect of external wind parameter could influence the optimum route which may vary depends on the speed of the wind.

Abstract

An alternative energy source that can be utilized in Indonesia is solar energy, this energy is obtained from the intensity of solar radiation and then, is converted into electrical energy with solar panels technology. The performance of the solar panel is strongly influenced by the surface temperature of the panel because the semiconductor material in the panel is sensitive to temperature changes. However, the cooling process in solar panels to maintain temperature panels is important. This study combines the use of a cooling box and fins by considering fins with a very limited area. Experiments were carried out to observe natural and forced convection with or without fins in a cooling box. The results obtained that the natural convection cooling process of the panels using the cooling box and fins (without airflow) can reduce the temperature of the solar panels by 3.52%, on the other hand, by using forced convection process (with airflow), the cooling box and fins can reduce the temperature of solar panels by 3.78%. The effectiveness of fins in the case without airflow is 24.63%, but then the case of airflow cooling of solar panels is 16.63%. The addition of fins on natural convection cooling (without airflow) of solar panels causes the heat transfer area to increase, thereby increasing the rate of heat transfer between the solar panels and the air.

Abstract

Salah satu metode sand control yang umum digunakan oleh perusahaan oil dan gas untuk pekerjaan perawatan sumur adalah sand consolidation (SCON). Selama ini, proses pemilihan provider pelaksana pekerjaan dilakukan secara lelang. Kemudian pimpinan departemen dan engineer akan memutuskan providernya. Agar proses pemilihan lebih transparan, terukur dan bisa dipertanggung jawabkan, maka diperlukan suatu sistem pengambilan keputusan yang standar dan kompatibel. Penelitian ini bertujuan untuk mengetahui parameter apa yang menjadi dasar pertimbangan dan merancang sistem pengambilan keputusannya. Metode yang digunakan dalam penelitian ini adalah Analytical Hierarchy Process (AHP). Hasil dari penelitian ini menunjukkan kriteria yang dijadikan sebagai pertimbangan adalah compatibility (0,349), safety & environment (0,229), quality (0,219), cost (0,127), dan service (0,075). Alternatif ST-α2-HL dengan bobot 0,282 merupakan provider terpilih. AHP dapat diterapkan sebagai metode yang sangat baik dalam kasus penentuan best alternatif provider SCON. Perbandingan hasil antara decision maker dan metode AHP jika dilihat dari perspektif best alternatif saja mencapai 100%.
