Perencanaan Filter Pasif untuk Meningkatkan Kualitas Daya Listrik di Kampus Diploma III Fakultas Teknik Undip
Full text linkArkhan Subari, Saiful Manan, in this paper explain that most electronic equipment is non-linear load. Likewise with the equipment in campus buildings Diploma III Faculty of Engineering. Non-linear load is a load that has a voltage waveform supplied from non sinusiodal although sinusoidal voltage. Non-sinusoidal wave causes the shape of the voltage becomes distorted or defects that result in decreased quality of power. The defect wave called harmonics. To dampen harmonics on non-linear load can be used filter. With the addition of a filter on the power system, then the waves of unwanted harmonics can be suppressed as small as possible. In addition, harmonic filter at the fundamental frequency can compensate for reactive power and is used to improve the power factor of the system. From the measurement results in the Diploma Program Campus FT Undip found that the influence of harmonic waves big enough. THDv reached 32.13% while the THDi amounted to 7.85%. It affects so cos phi cos phi measured just 0.72. After the installation of a passive filter, the value THDv and THDi be good lebik ie 1.61% and 0.39% to reach 0.94 cos phi measured

Full text linkThe proposed project is focus on understanding the suitable criteria for grape plantation and establishment of land suitability map of grape for new plantation area by using AHP (Analytical Hierarchy Process) approach. Grape is one of the most important fruit crops of the world. It is also one of the most ancient crops known to people. Grape is also well known as one of the demanded fruits in Malaysia, expensive and exclusive fruits, because it hardly to be grown in tropical climate. Today, there are certain types of grapes that can be planted in Malaysia and it had been proved by the Perlis Department of Agriculture. Thus, there are also some of Malaysian citizen that bravely plants the grapes such as in Sendayan Valley and Beris. Nowadays many people become excited on planting the grapes. This research study is with intention to explore and determine the suitable criteria and area for grapes plantation in Perlis State. The analysis is made based on the agro-climatic, soil series and the location of land with co-relation to the road network and terrain condition. The analysis is done through the Geographic Information System (GIS) using AHP (Analytical Hierarchy Process) approach. The analysis tools that been use such as intersect, buffer zone and erase tools is used based on the criteria being chosen. Finally, the potentially grape plantation area map is generated and zone for suitable and marginal suitable for grapes plantation in Perlis State is presented. The results demonstrated that GIS driven by AHP (Analytical Hierarchy Process) multi criteria decision making approach was able to accurately generate potential grape plantation area map for the study area. Fundamental technical and methodological developments resulting from this research will have significant impacts upon the GIS community
Digital Close Range Photogrammetry (DCRP) in façade recording and 3D as-built mappping for cultural heritage building / Abd. Manan Samad, Mat Rahim Ibrahim and Saiful Aman Sulaiman
Full text linkThe proposed research study is focus on the significant to contribute to the Malaysia in cultural heritage conservation where the data can be used in re-build the buildings or objects. It will also prepared for engineers and others professionals in the field of construction and heritage conservation for their reference. The scope of this research study will be focusing on comparing the methods in cultural heritage recording with conventional method and Digital Close Range Photogrammetry (DCRP). The process of recording only involve the outside structure, the interior structure not be included. Since the public is getting more concerned about conservation of cultural heritage features, it is predictable that more will make use of 3D models to explain their projects as 3D would provide excellent visual appreciation of the spatial relationship of structures with existing environment and to record historical features to facilitate future maintenance and restoration works. Other than that, the result can be used as a reference for the future generation and very precious as Lorn Acton stated: “Ultimate history we cannot have in this generation, but we can dispose of conventional history, and show the point we have reached on the road from one to the other, now that all information is within reach, and every problem has become capable of solution.

PENGARUH PERUBAHAN BEBAN TERHADAP TEGANGAN INTERNAL PEMBANGKIT PADA SISTEM TENAGA LISTRIK
Full text linkThe fluctuation of load conditions especially that is happened when the peak load condition, ifs called power system dinamics. It will influence to the stability and quality of electric energy system throughlly both, generators and customer as user of energy. This influence will seek directly on plant system as supplier of electric power system, more over if this power system includ the large area and plants system includ many types of generation.
One of qualities which must be sufficient by the power system is stable voltage if change or fluctuation load is occur, especially at the peak load condition That's to be known because the voltage quality on the consumer is depend on the internal voltage which is generated by generators of plants system.
Kondisi beban yang fluktuatif khususnya yang terjadi saat beban puncak pada konsumen, akan sangat berpengaruh terhadap kestabilan dan kualitas sistem tenaga listrik secara keseluruhan baik pada pencatu tenaga listrik maupun pada konsumen sebagai pemakai energi listrik. Pengaruh ini akan secara langsung terasa pada sisi pencatu beban. Apalagi jika pencatu beban tersebut mencakup daerah yang cukup luas, serta terdiri dan beberapa jenis pembangkit tenaga listrik
Salah satu kualitas yang hams dipenuhi oleh penyedia energi listrik itu adalah tegangan yang stabil jika tedadi perubahan beban, khususnya pada saat beban puncak. Hal ini perlu diketahui karena kualitas tegangan pada konsumen tersebut sangat tergantung dari tegangan pencatu daya yang dibangkitkan oleh pem¬bangkit-pembangkit pencatu daya tersebut
