A COMPUTER CALCULATION FOR TENTATIVE ELECTRICAL SYSTEM IMPROVEMENT BY REACTIVE POWER COMPENSATION CONSIDERING SYSTEM UNBALANCED

An improvement of unbalanced distribution system operation is carried out by reactive power compensation. The lagging reactive power demand is compensated by allocating a number of three-phase shunt capacitors. At the stage, the compensation devices are determined tentatively in term of number, size and location. The effects of the installed shunt capacitors are then analyzed. The unbalanced condition of distribution system is taken into account due to the fact that distribution system is inherently imbalance. For three-phase unbalanced power flow analyses, forward-backward propagation algorithm is proposed. The algorithm works directly on the system without any modification. Starting with determination of forward and backward propagation paths, the algorithm calculates branch currents using backward path. With the branch currents in hand, the bus voltages are calculated using the obtained branch currents and line impedances. Equivalent injection currents representing loads and shunt admittances method are required. The algorithm offers robust and good convergence characteristics for radial distribution system. In this paper, reactive power compensation is simulated using tentative approach and the achieved system improvements are observed. The improvements are presented as losses minimization and voltage profile enhancement. The simulation is carried out for the IEEE 34-bus system, while the system improvements due system compensation are described. The generated results indicate that for further optimal system improvement, an optimization technique is require

Analisa regresi kelompok

ABS TRAK Analisa regresi kelompok adalah sebuah teknik statistik untuk membuat model dan menyelidiki hubungan antara dua variabel atau lebih, dimana data yang tersaji dalam bentuk data yang dikelompokkan. Metode pengelompokan data dengan nilai rata-rata kelompok yakni data ash dikelompokkan dalam interval-interval atau kelompok-kelompok tertentu kemudian data ash dalam setiap kelompok digantikan dengan nilai rata-ratanya. Teknik analisa regresi menggunakan data kelompok pada dasarnya adalah perluasan dari teknik analisa dengan menggunakan data ash. Model regresi untuk data yang dikelompokkan memiliki variansi kesalahan acak tak konstan sehingga penaksiran koefisien regresi dengan metode GLS, dimaksudkan untuk mendapatkan penaksir yang memiliki sifat BLUE. Penaksiran koefisien regresi dengan menggunakan data kelompok memiliki variansi koefisien regresi lebih besar dan pada uji signifikansinya memberikan analisa yang kurang peka dibandingkan dengan menguna.kan data ash. Selain itu juga tidak didapatkan sesatan murni pada model regr esi dengan data kelompok sehingga tidak dapat dilakukan pengujian kecocokan model, dan untuk mempertimbangkan model digunakan nilai koefisien dtenninasi

Matrik transformasi pada model linier dengan gangguan dalam proses rata-rata bergerak

ABSTRAK Estimasi parameter persamaan regresi linier dengan asumsi gangguan berautokorelasi tidak didapatkan estimator yang BLU atau BLUE (Best Linier Unbiased Estimator). Untuk kasus gangguan berautokorelasi dengan proses rata rata bergerak (RB), BLUE dapat diperoleh kembali dengan mencari Transformasi yang cocok pada model linier yang asli sedemikian sehingga estimasi OLS (Ordinary Least Square) pada model regresi tertransformasi menghasilkan GLSE (Generalized Least Square Estimator)

DETERMINING LANGUAGE TYPOLOGY BASED ON DIRECTED MOTION LEXICALIZATION PATTERNS AS A LANGUAGE DOCUMENTATION: A CASE STUDY ON JAVANESE

Every language has directed motion constructions, but the lexicalization pattern of the constructions may differ from one language to another. The similarities and differences of directed motion lexicalization patterns can be used as the basis for classifying languages typologically. This paper aims to discuss how language typology can be determined based on directed motion lexicalization patterns found in a language. In this study I use the data of Javanese to examine whether Javanese can be classified into Talmy’s (1975, 1985) typology of verb-framed or satellite framed languages. Some problems and implications of this language typology will be discussed to see whether there is interaction between directed motion lexicalization patterns and other syntactic structures. The data of Javanese show that Javanese has some verb framing and satellite framing characteristics, and so language typology is not exactly definite in the sense that there are some restrictions that need to be considered

KAJIAN PENERAPAN ZoSS (ZONA SELAMAT SEKOLAH) DI KOTA BOGOR

Placing of (location) school facility (elementary school) as basic equipment facilitation of environment is sometimes accessible to road gives feeling of insecure/unsafe, cause of its impact on interaction conflict within its user (especially toward children). As implementation in giving saving protection to children, by traffic calming concept is thereby Schoolyard Secure Zone program (ZoSS),that is ; location on the road side which time based velocity road to manage vehicle speed around elementary school especially on school rush hour, to protect pedestrian walker mainly toward elementary school student and the danger of traffic accident. ZoSS implementation is effort to optimize road function as city facilitation by managerial on road operation as effort in administering movint system on road link to increase movement efficiency and safety of traffic user, which dependently toward road’s function classification. This observation is aimed to study the implementation of ZoSS at 3 (three) different locations in Bogor City, that are; SDN 1 Cibuluh, SDN I Batutulis and SD Mardiwaluyo, toward pedestrian walker, the walker perception and traffic performance. The observation method which used is quantitative descriptive, and the sample collection technique is Simple Random Sampling by Z-test statistics analysis for pedestrian user, and Accidental Sampling by descriptive analysis for traffic user, then traffic performance analysis toward service quality (V/C ratio), Level Of Service (LOS) and the velocity (V). The analysis yielded that ZoSS as conditional learning stated can change traffic user behavior, which the user is prone to do in save manner (value Z-count > Z-table) with error is 5%. While the traffic user perception, show that implementation of ZoSS has give secure feeling toward elementary student when crossing, but for parent SD still has anxiety toward driver’s manner. Vehicle velocity at roadside in implementation ZoSS under save category (under maximum limit of 20 km/h), which contradictive with minimum velocity planed (PP No. 34/2006) 30 km/h for secondary artery road, 20 km/h for secondary collector road. The implementation of ZoSS in Bogor city affects toward traffic performance by V average ranged within 17-24 km/h and VCR in scoped 0,0 - 0,6 which showed that LOS on E category with unstable flow characteristics, low speed, maneuver activity in traffic flow and direction changing were difficult to do and caused vehicle treading. Those conditions are continue, meanwhile management effort and traffic administration will only fixes capacity by decreasing the source, and therefore, must be considered in consistent way about long term solution in fixing traffic system based on road function classification. The ZoSS Implementation on collector and local road sides can be considered, but the implementation on artery road side need to be reviewed and toward inconsistency of artery road function which have conducted, need to be given alternative solution : 1) dividing expressline and slow line, by crossing facility on roas as JPO or underpass, 2) decreasing road function classification, but it should be existed alternative road which accommodate secondary road function. It is need improvement on further observation comprehensively by comparing performance between ZoSS crossing area with conventional “zebra cross”. Therefore, toward alternative handling on fixing the traffic artery road, it is need conducted further study related toward traffic pattern formation based facilition system and transportation demand, concord with direction of Bogor city development.

KONSEP PENDIDIKAN AKHLAK PERSFEKTIF HADIS (Telaah Terjemahan Kitab Al-Lu’lu Wal Marjān)

Character degradation has occurred in many places, especially Indonesia. Whereas in Islam, the concept of morality has been formulated mainly on normative sources, especially the hadiths of the Prophet. Many Muslims lack hadith literature, especially for laymen, even though there are so many books of hadith translation and are suitable for reading for laymen. Among the translated books that can be accessed by is the book Al-Lu'lu Wal Marjān which contains all the sahih hadith with matan narrated equally from sahih Bukhari dan Muslim. In addition to being a recommendation related to the source of hadith literacy, this study also aims to explore how the concept of moral education in the form of narration and behavior exemplified by the Prophet Muhammad during his life. Researchers use qualitative research methods, qualitative research is research that raises information descriptively, both in the form of written words, spoken and the behavior of someone being studied. Qualitative is often referred to as research whose conditions are natural, so that the data collected is factual. The results of this study explain that the concept of moral education contained in the hadith that has been studied consists of 4 pillars, namely morals to Allah, the Messenger of Allah, fellow humans and oneself. implementation of morals to Allah by carrying out all commandments and avoiding all moral prohibitions to Allah by worship, to the Messenger of Allah by imitating him, , to one's fellow man by doing good, and to oneself by not burdening difficult things

ANALYTIC CAUSATIVES IN JAVANESE : A LEXICAL-FUNCTIONAL APPROACH

This paper is a study of analytic causatives in Javanese from a Lexical Functional Grammar (LFG) perspective. Analytic causative s are the type of causatives where there are separate predicates expressing the cause and the effect, that is, the causing notion is realized by a word separate from the word denoting the caused activity. The question addressed in this paper is whether analytic causative s form a mono - or bi - clausal structure. In addition, this paper aims to explain the mechanism of argument sharing between the verbs involved in analytic causatives. By using a negation marker and modals as the syntactic operators to test mono - or bi - clausa lity of analytic causatives, it was found that analytic causatives in Javanese are biclausal. These constructions have an X - COMP structure, in that the SUBJ of the second verb is controlled by the OBJ of the causative verb (N)gawe ̳make‘. The syntactic str uctures of analytic causatives are described within a constituent structure and a functional structure, two main components of LFG
