In developing Sultan Hasanuddin Airport Makassar, one of the efforts is by installing Approach Light System, a navigation tool installed at both runway edges used to improve flight security and safety. By installing Approach Light System at both runway edges, it can guarantee safety flight in order to develop air traffic system in the movement area that is safe, fast and smooth.The objective of Approach Light System is to provide clear guides to pilots when performing landing on the runways. The tool is also useful for making accurate landing of the aircraft.By using descriptive qualitative technical approach method in the analysis of this study, it can be concluded that by completely installing the Approach Light System at both runway edges in Sultan Hasanuddin Airport, it has met the regulation number SKEP/114/VI/2002 on the Airport Installation System Standard Blueprint (Airfield Lighting System) issued by the General Directorate of Air Transport so that safe and secure flight can be conducted optimally and aircraft movement can be increased as well.Approach Light System merupakan peralatan navigasi pada kedua ambang landasan untuk meningkatkan keamanan dan keselamatan penerbangan. Tujuan dan manfaat dari Approach Light system adalah untuk memberikan tuntutan kepada pilot/penerbang saat melakukan pendaratan menuju landasan dan manfaatnya untuk ketepatan pendaratan pesawat udara.Melalui metode pendekatan teknis deskriptif kualitatif dalam melakukan analisis pembahasan dapat disimpulkan bahwa dengan terpenuhinya kebutuhan Approach Light system pada kedua ambang landasan bandara Sultan Hasanudin Makassar, maka sudah sesuai dengan ketentuan yang berlaku yaitu SKEP/114/VI/2002 yang diterbitkan oleh Direktorat Jenderal Perhubungan Udara tentang Standar Gambar Instalasi Sistem Bandar Udara (Airfield Lighting System) sehingga dapat terselenggara keamanan dan keselamatan penerbangan secara optimal dan dapat meningkatkan pergerakan pesawat udara.

Tracing Method

The study computes the availability of street lighting system in Warri. This system under study consists of subsystems that are known as workstations. A generator and sets of street light make up a workstation. The power source and the street lighting were modeled into series and parallel  combinations. Reliability Block Diagrams and Path Tracing Method were employed assuming independent failure of the components. The availability of the set of street lightings, workstations and hence the availability of the system were determined. Results of the study show that users in Cemetery road had the least availability of 62.19% for the period. The implication is that users travelling along this road experienced wide variation of light that could lead to accidents. Keywords: Availability, Street Lighting and Reliability block diagram

The Monte Carlo Method

The article has considered the calculation of the unified glare rating (UGR) based on the luminance spatial-angular distribution (LSAD). The method of local estimations of the Monte Carlo method is proposed as a method for modeling LSAD. On the basis of LSAD, it becomes possible to evaluate the quality of lighting by many criteria, including the generally accepted UGR. UGR allows preliminary assessment of the level of comfort for performing a visual task in a lighting system. A new method of "pixel-by-pixel" calculation of UGR based on LSAD is proposed.

Prediction Approach

The air traffic is mainly divided into en-route flight segments, arrival and departure segments inside the terminal maneuvering area, and ground operations at the airport. To support utilizing available capacity more efficiently, in our contribution we focus on the prediction of arrival procedures, in particular, the time-to-fly from the turn onto the final approach course to the threshold. The predictions are then used to determine advice for the controller regarding time-to-lose or time-to-gain for optimizing the separation within a sequence of aircraft. Most prediction methods developed so far provide only a point estimate for the time-to-fly. Complementary, we see the need to further account for the uncertain nature of aircraft movement based on a probabilistic prediction approach. This becomes very important in cases where the air traffic system is operated at its limits to prevent safety-critical incidents, e.g., separation infringements due to very tight separation. Our approach is based on the Quantile Regression Forest technique that can provide a measure of uncertainty of the prediction not only in form of a prediction interval but also by generating a probability distribution over the dependent variable. While the data preparation, model training, and tuning steps are identical to classic Random Forest methods, in the prediction phase, Quantile Regression Forests provide a quantile function to express the uncertainty of the prediction. After developing the model, we further investigate the interpretation of the results and provide a way for deriving advice to the controller from it. With this contribution, there is now a tool available that allows a more sophisticated prediction of time-to-fly, depending on the specific needs of the use case and which helps to separate arriving aircraft more efficiently.

Street Lamp

This research proposes a simple but very effective method to determine faulty street lamps by utilizing a microcontroller associated with relay control technique to analyze the current consumption of the lamps. With such approach, the lighting system can automatically report the number and the position of the faulty street lamp to the operator in the control room. As a consequence, the faulty street lamp can be quickly repaired. The user interface and controller are programmed in LabVIEW software. The result is verified by modeling street light system using five 100 watts incandescent light bulbs connected in parallel. The results of this research can be applied to improve the existing street light system especially in Thailand. Furthermore, equipment used in this research is cost effective.
