Konstitusionalitas Badan Peradilan Khusus dan MK dalam Penyelesaian Sengketa Hasil Pilkada Langsung
Authors: Suhartono Slamet
Published: October 2018

In accordance with the decision of the Constitutional Court Number 97/PUU-XI/2013, the Constitutional Court is no longer authorized to resolve disputes on direct election results, because the provisions of Article 236C of Law Number 12 Year 2008 NRI are against the Constitution of 1945. Article 157 paragraph (1) Law No. 8 Year 2015 determines that the dispute settlement on direct election results become the authority of specialized judiciary. But before a specialized judiciary is formed, then the Constitutional Court is authorized to resolve disputes on direct election results. The authority of the Constitutional Court is the constitutional authority to fulfill temporary legal vacuum (rechtvakum). Therefore legislators should immediately establish a specialized judiciary which has the authority to resolve the disputes on direct election results.
Rekonstruksi Politik Hukum Pidana Nasional (Telaah Kritis Larangan Analogi dalam Hukum Pidana)

A paradigm shift in the state of life—especially post the Constitution of the Republic of Indonesia 1945 amendments—have not been fully understood  properly. Up to now—included in the lawless life—is still a gap between the paradigm and its implementation . This paradigmatic gap visible example of the lack of a comprehensive implementation of the basic principles of the Constitution of the Republic of Indonesia 1945 in a national criminal law reform ( draft Code of Criminal Law ) . The draft Code of Criminal Law as one form of national criminal law reform is seen has not fully represent constitution demands. Prohibiting the   use of analogy in criminal law is still seen at odds with the provisions of Article 1 ( 3 ) of the Constitution of the Republic of Indonesia 1945. The gap is not only paradigmatic potential to cause difficulties in its application, but also potentially the cancellation clause in the legislation  concerned.
Ultra Petita dalam Pengujian Undang-Undang oleh Mahkamah Konstitusi
Authors: Abadi Suwarno
Published: October 2018

Ultra petita decision practiced under the MK’s jurisdiction to review the constitutionality of legislation needs to be assessed carefully. This practice should not be condemned as illegitimate because there is no explicit constitutional rule that guarantee it. The author therefore argues that this practice can be justified under two reasons. First, judicial activism. Second, the very nature of constitutional adjudication in order to defend the supremacy of the constitution over legislation. According to these reasons, the MK’s ultra petita decision should be upheld because this practice is the most reasonable means to protect the constitution.
Kebebasan Hak Ijtihad Nikah Beda Agama Pasca Putusan Mahkamah Konstitusi
Authors: Tobroni Faiq
Published: October 2018

This paper has three key issues. The first issue discusses the arguments constructed by applicant of judicial review (JR) to assess the constitutional rights’ violations caused by the application of Article 2 (1) UUP. The second issue discusses on how the Constitutional Court (MK) seated position of state associated marital affairs in the rejection of JR. The third issue discusses model of freedom of ijtihad (legal thought) on interfaith marriage as the impact of MK’s Decision. Based on    the discussion, regarding to the first issue, the applicant of JR assess the application of Article 2 (1) UUP has legitimized the state as the sole interpreters of religious teachings for a requirement validity of the marriage. According to the applicant,  the role is used by the state (The Office for Religious Affairs/KUA) to not accept interfaith marriage. This refusal led to the violation of some other constitutional rights. Furthermore, as the findings of the second issue, MK’s decision has placed   the real position of state not as interpreters of religious teachings, but merely to accommodate the results of religious scholars’s ijtihad regarding marriage into the state law. Thus, it is not true that the state has violated the constitutional right to more intervene the religious life of citizens. Last findings as the third issue, MK’s decision has affected the model of ijtihad freedom on interfaith marriage. Actually interfaith marriage can still be served through the Civil Registry Office (KCS). KCS could be an alternative way to facilitate the interfaith marriages for all religions in Indonesia. Special for KUA, the institution reject to record interfaith marriage.   In this way, it only accommodates freedom of ijtihad within the limits of ijtihad jama’i. KUA just accomodates ijtihad by institutions such as the Majelis Ulama Indonesia, Nahdlatul Ulama, Muhammadiyah and other similar institutions that reject interfaith marriage. Special for marriage in muslim community, ijtihad jama’i is better than ijtihad fardiy because the second could trigger the liberalization of marriage laws (temporary marriages, polygamy more than four, underage marriages and denial of recording).

The position of Regional Representative Council in the context of the implementation of the legislative function has an important role in order to create the principle of checks and balances between state institutions which include the House of Representatives and the President. Contextually Constitutional Court Decision No. 92/PUU-X/2012 reinforce the DPD position both in terms of national legislation program planning, delivery of opinions, views, list of inventory issues,  and discussion of a draft law. Much progress has been achieved but in the political realm seems legislative authority of the DPD is still not perfect when not reached the stage of deciding to join a draft law being discussed. In order to strengthen    DPD as part of regional representation, the amendments to the Constitution of  1945 was important to conduct state institutional arrangement holistically and comprehensively.

The Pro’s – Con’s of the Constitutional Court in the review of law in a regulated of the authority, since, it was a conflicting of procedural principles between “ius curia novit” with “nemo judex idoneus in propria causa”. Morever, the background by implication of Constitutional Court decisions, sometimes Constitutional Court making a “rule breaking”,  for examples: nullify of some of law if had reduction of  the authority, addition of constitutional authority to review of law before the 1945 Constitution amendment, additional authority to review of Government Regulation in lieu of law, and used non-constitution as a standard in the formal review, and others. On the other hand, the Constitutional Court also sometimes to choose a   legal logic doesn’t precise and anti-accountability principle. The Conflicts of the procedural principles can  be  resolved  by  understanding  philosophy  of  purposes of law (justice value, legal certainly, utility principle), so that, the Court will have been prioritizing to “ius curia novit” principle and it ignored “nemo judex idoneus  in propria causa”principle, it is intended that the enforcement of the constitution (values) and the state of the Indonesian rule of law, as well as for the Court to aims decided of constitutional issues and to aim the protection of constitutional rights.

Hukum dan Keadilan Sosial dalam Perspektif Hukum Ketatanegaraan
Authors: Sumadi Ahmad Fadlil
Published: October 2018

Law in this discussion is the law that is deliberately formed (by designed) by  the state, not the law that occurs naturally in the society, which constitute the crystallization of human interaction within the society as the subject of law.  Law is known as the common law or customary law and the second is the religious law, in particular, Islam with its Islamic law. The process of formation of common law or customary law is from the bottom upward (bottom-up process) while the establishment of islamic law is from top to bottom (top-down). The same as the nature of the process of formation of Islamic law is the in question in this discussion, which is the law called state legislation, or which is also usually known as laws and regulations. The only difference is, Islamic law is made by God, Allah SWT,  while the maker of statutory laws is a state institution of which the major function is to make laws (legislative power). Legislation is interrelated to with humanity and justice, both in the establishment, implementation, and enforcement. This can be proven by tracing since the establishment of the state, particularly Indonesia, because the law is one of the implementation of state functions. State is established on the basis of motivation associated with humanity and justice, so that the objectives and the foundations are also related to humanity and justice. The State and the law is  an instrument of humanity and justice, therefore, state and law must be related to humanity and justice, and thus, also would not be enough in the instrumental perspective, the state and the law itself without humanity and justice in serving the society.
Review of Recent Advances in Vaginal Mesh Tissue Interaction
Authors: Chanda Arnab
Published: October 2018

Pelvic Organ Prolapse (POP) is a critical deformity of the female pelvic floor suffered by over millions of women in the US. POP leads to prolapseof pelvic organs onto the vaginal canal causing discomfort, pain, strain and sexual dysfunction. Vaginal meshes are traditionally implanted surgicallyto rectify the herniation of the pelvic organs and correct patient-specific POP conditions. However, the bio incompatibility of such meshes within thefemale pelvic system have been recognized to be deletarious to the surrounding tissues due to mesh erosion, organ perforation and tissue slicing,leading to severe complications. In literature, several studies have been conducted to understand vaginal mesh mechanical properties and mesh tissueinteractions. The current article reviews these recent advances, which will not only be valuable to understand the state of the art in the mesh tissueinteraction characterization and the directions in which further work needs to be conducted, but would also be indispensable for understanding thechallenges associated with vaginal mesh failure and the corrective strategies in terms of design and implementation moving forward.
Thought, pattern and consciousness
Authors: Yu Xiaoyang
Published: October 2018

Thought can be copied from one person to another. Thought is a pattern. Pattern is more than thought. Patterns are everywhere. Pattern can be copied between nonlife and life. For example, when a person sees a ball, the ball's shape as a pattern can be copied into the person's mind. When the person says the word "ball", the sound "ball" is a pattern copied from the ball in his mind.Currently we know that consciousness only arises in complex neuron network of life. Consciousness contain patterns. The feeling of having consciousness in oneself's mind is a pattern. This pattern can be copied. A person can describe the content of his consciousness, and other people will get it.Consciousness is something new invented in life's evolution. It is real. People do have consciousness, they are not zombies who don't have consciousness but can act as if they have it. Being consciousness created some new thoughts in human kind's mind.Patterns copied among people. Most thoughts in one's mind are copied from other people. The thoughts in one's mind control this person. The person is controlled by his thoughts. He can't control his thoughts. A person decides something is true or false by his physiological activity. If a person decide that something is true, that thing can be true in reality, and it is also possible that that thing can be false in reality. The problem is that a person cannot know whether the thing is true or not in reality, although he can decide it in his mind. "True" or "false" are two concepts. All other concepts have the same problem. Human have concepts in their mind, and they can be copied among people, but they cannot be defined precisely enough. In fact, there is no way to define any concept really precisely. All definitions will use words, but we can't define any word without using other words. For example, what is "red"? How to define red as a color precisely? And how do we define "color"? How can we explain the concept "color" to a blind person? We can't.

The Impact of Translation Techniques on Politeness Strategies in Giving Advice
Authors: Ardi Havid , Nababan M. R. , Djatmika  , Santosa Riyadi
Published: October 2018

Giving advice is a common speech act but potentially problematic as it may threaten the face of the hearer. The speaker will use politeness strategies to mitigate face threatening act in giving advice. Politeness strategies as mitigation are not only appeared in real conversation but also in fiction. Thus it raises a question how translators deal with politeness marker in giving advice in intercultural context. This paper aims at exploring the translation of politeness markers in giving advice used by the main characters in the novel Deception Point written by Dan Brown (2001). Data were the utterance of advices made by main characters in the novel Deception Point and its two Indonesian translation version. Data were taken by document analysis and focus group discussion in classifying the translation techniques. The result show that 1) there are only two main characters who give advice due to the felicity conditions of advice, 2) positive and negative politeness strategies are employed by the main characters in giving advice, 3) there is a change in the translation caused by the implementation of translation techniques to the politeness markers.
POLITENESS IN MAKING REQUESTS USING MODAL AUXILIARIES IN EFL SPEAKING CLASS
Authors: rakhmawati deny efita nur
Published: October 2018

People communicate each other mostly by using spoken language. During the communication, they cannot avoid using modal auxiliaries especially in asking their interlocutors which then it influences the politeness of the utterances. This research, therefore, discusses the students’ usage of modal auxiliaries in speaking class. Here, the modal auxiliaries are found during their performances in the classroom. It is integrated into the English Language and Literature classes in Sunan Gunung Djati Islamic State University in the year 2012. While carrying out the research, qualitative research method is employed. Data are mainly gathered through the observation by recording of students’ performances and interview. The research reveals that ‘can’ is the highest occurrence of modal auxiliaries used by the students (43%). Moreover, 90% students in speaking class tend to produce positive politeness. ‘Can’ is in the highest occurrence since the students think it as the simplest modal and most heard in daily communication, while the positive politeness tends to appear since they consider that they need to create refined communication with the interlocutors. At the end, it is hoped that this research might inspire the English lecturers to be more aware of students’ politeness during speaking English.

Development of the Frankfurt Youth Acculturation Scale (FRACC-Y)
Authors: Bongard Stephan , Frankenberg Emily , Kupper Katharina
Published: October 2018

This paper describes the development and psychometric properties of the Frankfurt Youth Acculturation Scale (FRACC-Y), a bidimensional instrument designed to assess orientation to culture of origin, orientation to host culture and acculturation strategy (i.e. assimilation, integration, separation and marginalization). Data were obtained from 292 adolescents in two German cities. Results of confirmatory factor analysis supported the postulated two-factor solution. The first 7-item factor measures orientation toward host culture, the second 5-item factor assesses orientation toward culture of origin. Both subscales yielded adequate internal reliability. Evidence for concurrent and discriminant validity is provided and implications for future research of acculturation in adolescents are discussed.
Analysing cultural frequency data: neutral theory and beyond
Authors: Kandler Anne , Crema Enrico R.
Published: October 2018

In this chapter we review the application of neutral theory to archaeological case studies. In particular, we focus on commonly used neutrality tests and discuss the interpretation of their results. We argue that one needs to be careful with interpreting the consistency (or inconsistency) of archaeological data with theoretical neutral expectations as evidence for the absence (or presence) of selective force in the population. While neutral theory does very well in replicating various population-level frequency patterns, many alternative processes of cultural transmission may do so, too, making the pattern-matching approach a fairly weak approach for inferring underlying transmission processes. We advocate the use of generative inference frameworks as one possibility to go beyond the hypothesis testing approach. These frameworks do not only allow for the identification of the most likely underlying learning process given the empirical data but for a description of the breath of processes that could have produced these data equally well. This brings us a step closer to understanding the limits to inferring underlying transmission processes from population-level frequency data and therefore the kinds of questions can be answered with which kinds of data.
The ‘new’ League success in the red belt and its post-fascist inheritance: evidence from 2018 National Elections
Authors: Mancosu Moreno , Ladini Riccardo
Published: October 2018

In 2018 national elections, the Lega, an Italian xenophobic right-wing party, has dramatically increased its consensus in the ‘red belt’, the central part of the country traditionally ruled by center-left parties. Pundits have argued that this performance can be attributed to the effect of the new leadership of Matteo Salvini, who shifted the ideological location of the party (that now aims at being a national right-wing party), combined with the drop in preferences of Forza Italia, the ally/competitor in the right-wing ideological spectrum. This paper aims at providing new insights in the explanation of these electoral outcomes, by hypothesizing that geographical trajectories of diffusion of the party are correlated with the presence of geographically clustered post-fascist minorities present in the region since the First Republic age. By employing official figures at the municipality level, the paper analyses the relationship between the percentages of votes for the MSI (the most relevant post-fascist force during the First Republic) in 1976 and the Lega Nord in the 2006-2018 period. Consistent with our hypothesis, the post-fascist inheritance is significantly correlated with the local prevalence for the Lega Nord in 2018, after the change in the political discourse and leadership of the party. Empirical analyses provide evidence of our expectations, even when controlling for unemployment rate and percentage of immigrants.
Strategies for the Heat Treatment of Steel-Aluminium Hybrid Components
Authors: Herbst S. , Maier H. J. , Nürnberger F.
Published: October 2018

The production of massive steel-aluminium hybrid components by means of massive (hot) forming following a joining operation requires advanced heat treatment strategies for the adjustment of local material properties with maximum joint strengths. For the given process-step sequence, the challenge is that the heat treatment of the hybrid component can only take place in the joined state and after (hot) forming. Consequently, suitable heat treatment strategies must enable both a T6 heat treatment of the aluminium component and a surface hardening of the steel component. It could be shown that the inductive surface hardening of a steel functional surface in the immediate vicinity of the aluminium component can take place without reducing the bond strength. To achieve the desired hardening result, the use of a field former is required. The bond strength could be increased by up to 20% compared to the friction-welded initial conditions by adjusting the parameters of the T6 heat treatment.
WEB-BASED PERSONAL DIGITAL PHOTO COLLECTIONS: MULTIMODAL RETRIEVAL
Authors: Ismail Nor Azman , O'Brien Ann
Published: October 2018

When personal photo collections get large retrieval of specific photos or sets of photos becomes difficult mainly due to the fairly primitive means by which they are organised. Commercial photo handling systems help but often have only elementary searching features. In this paper, we describe an interactive web-based photo retrieval system that enables personal digital photo users to accomplish photo browsing by using multimodal interaction. This system not only enables users to use mouse click input modalities but also speech input modality to browse their personal digital photos in the World Wide Web (WWW) environment. The prototype system and it architecture utilise web technology which was built using web programming scripting (JavaScript, XHTML, ASP, XML based mark-up language) and image database in order to achieve its objective. All prototype programs and data files including the user’s photo repository, profiles, dialogues, grammars, prompt, and retrieval engine are stored and located in the web server. Our approach also consists of human-computer speech dialogue based on photo browsing of image content by four main categories (Who? What? When? and Where?). Our user study with 20 digital photo users showed that the participants reacted positively to their experience with the system interactions.
DESIGN AND PERFORMANCE ANALYSIS OF VCO FOR STANDARD GSM USING MEMS
Authors: Al-Khateeb Khalid A. S. , Al-Khateeb Wajdi F.
Published: October 2018

The design of a prototype monolithic Micro Electro-Mechanical Systems (MEMS) electronic circuits, namely the Voltage Controlled Oscillators (VCOs) is presented. The components can achieve the stringent requirements of wireless communication applications such as GSM cellular telephony. The VCO meets the low phase noise specifications of -136 dBc/Hz at large offset frequency of 3MHz, over the appropriate frequency range. The model of the monolithic VCO is based on the topology of the Colpitts Oscillator. It is relatively less complicated, which facilitates the practical integration of the MEMS components into the configuration. The variable capacitor and the monolithic 3-D coil inductor are suitable for low phase-noise and low power consumption at the application frequencies. A PSpice simulation model was developed with MEMS switching devices that can be integrated into the system. The model helps in determining the design parameters, which affect the performance and operation reliability of the RF transceiver system, for which a prototype has been tested and proved successful.
ROLE OF DISCRETE NATURE OF CHIP FORMATION AND NATURAL VIBRATIONS OF SYSTEM COMPONENTS IN CHATTER FORMATION DURING METAL CUTTING
Authors: Nurulamin A. K. M. , Jaafar I. H. , Patwari A. U. , Zubaire W. W. D.
Published: October 2018

In the present work a review of the existing theories of chatter formation has been conducted and the weaknesses of the most widely accepted â€˜Regenerative Chatter theoryâ€™ in explaining various phenomena related to chatter formation have been identified. An attempt has been made in this work to determine the common causes of chatter formation in different metal cutting operations, namely, turning, thread cutting and end milling conducted on plain carbon steel AISI 1040. Experimental investigations have been conducted during the above types of machining processes to identify the marks of instability and chatter on the formed chips. It has been identified that in all the three machining operations the chips formed show a common type of discreteness in the form of secondary saw teeth, which appear at the free edge of the chip. Mechanism of formation of these teeth has been studied and the frequencies of their formation have been determined for different cutting conditions. Apart from the secondary saw teeth primary saw teeth have also been identified at the main section of the chip and their frequencies were also determined. At the same time the natural vibrations of the main system components have been identified and the acceleration amplitudes at the prominent natural frequencies during actual machining were recoded using a dedicated vibration monitoring system. The frequencies of secondary chip serration and the natural frequencies of the system components were plotted against cutting speed. Acceleration amplitudes at the prominent natural frequencies were also plotted separately against cutting force. Based on comparison and analysis of these two frequency and amplitude graphs it was concluded that chatter (vibration with relatively high amplitude) appears in the system when the frequency of secondary saw teeth approaches values equal to half or integer multiple of a prominent natural frequency of the system resulting in resonance. In the case of thread cutting and turning the main vibrating component was identified as the tool holder and in the case of end milling the main vibrating components were the tool holder and the spindle. Severe vibration/chatter was found to appear during end milling when the tool and the spindle simultaneously entered into resonance. This occurred when the chip serration frequency got close to the spindleâ€™s natural frequency, which was approximately twice the value of the natural frequency of the tool holder in the conducted experiments.

ACOUSTIC EFFECTS ON BINARY AEROELASTICITY MODEL
Authors: Yu Kok Hwa
Published: October 2018

Acoustics is the science concerned with the study of sound. The effects of sound on structures attract overwhelm interests and numerous studies were carried out in this particular area. Many of the preliminary investigations show that acoustic pressure produces significant influences on structures such as thin plate, membrane and also high-impedance medium like water (and other similar fluids). Thus, it is useful to investigate the structure response with the presence of acoustics on aircraft, especially on aircraft wings, tails and control surfaces which are vulnerable to flutter phenomena. The present paper describes the modeling of structural-acoustic interactions to simulate the external acoustic effect on binary flutter model. Here, the binary flutter model which illustrated as a rectangular wing is constructed using strip theory with simplified unsteady aerodynamics involving flap and pitch degree of freedom terms. The external acoustic excitation, on the other hand, is modeled using four-node quadrilateral isoparametric element via finite element approach. Both equations then carefully coupled and solved using eigenvalue solution. The mentioned approach is implemented in MATLAB and the outcome of the simulated result are later described, analyzed and illustrated in this paper.

Authors: Yusliza Yusof , Zuraida Ahmad
Published: October 2018

ABSTRACT : The effect of fiber content on mechanical properties and thermal stability of the cotton/albumen composites (CAC) were investigated and presented in this paper. The composites having 0%, 3%, 6%, 10%, 13 %, and 16% w/w of cotton fiber were considered. Â Hands lay-up technique was used to prepare the CAC specimens and dried for 24 hours before characterised and evaluated for their mechanical performance. The structure and thermal stability of the composites were characterized by using x-ray and thermogravimetry analysis, respectively. The tensile strength and impact resistance of CAC are found maximum with the value of 8.7 MPa and 19.0 kJ/m2, respectively. Analysis on the morphological structure by SEM revealed that the mechanical properties of the composites depend on good wettability and adhesion between fiber/matrix.

Authors: Kim Kidong , Kwon Kijung
Published: October 2018

Surface pressure distributions on a rotating blade were measured by using pressure sensitive paint (PSP) to understand aerodynamic characteristics of a rotor blade. The present study was conducted to investigate the PSP techniques for measuring the pressure distributions on a rotor blade. In order to perform the experiment, the PSP was required to response very fast due to rapid pressure fluctuations on a rotor blade. High energy excitation light source was also needed to acquire proper intensity images in a short excitation time. The techniques were based on a lifetime method. Qualitative pressure distributions on an upper surface of small scale rotor in hovering condition were measured as a preliminary experiment prior to forward flight conditions in the KARI low speed wind tunnel laboratory. From measured pressure distributions, striking pressure gradient was observed on an upper surface of rotor blade and the resulting pressure showed expected gradient depending on different collective pitch angles.

Investigation of the Swirl Effect on Engine Using Designed Swirl Adapter
Authors: AKM Mohiuddin
Published: October 2018

Swirl is the rotational flow of charge within the cylinder about its axis. The engine used in this investigation is a basic Double Overhead Camshaft (DOHC) which has a capacity of 1597 cc and installed with a total of 16 valves developed by Malaysian car manufacturer PROTON. The swirl adapter is placed inside the intake port of the Engine. The Adapter angle is set to 30o to force the charge to bounce off the wall of the port to create swirl. The objective of this paper is to find the effect of swirl on the engine and to compare it with the normal turbulence mixing process. The swirl effect analysis is done by using the GT-SUITE which has a standard swirl flow embedded in the software. The effect is simulated on the GT-SUITE and it is found that the swirl affects the engine in reducing the fuel consumption and increasing the volumetric efficiency. The experimental result shows that the effect of swirl increases the power as well as torque in the idle and cruising speed conditions in comparison with normal turbulence. But it decreases rapidly in the acceleration speed. This happens due to the inability of the swirl adapter to generate swirl at higher wind flow velocity during the higher throttle opening condition.ABSTRAK: Pusar merupakan aliran putaran cas melingkungi silinder pada paksinya. Enjin yang digunakan untuk penyelidikan ini merupakan Enjin Aci Sesondol Stas Kembar (Double Overhead Camshaft (DOHC)) asas, yang mempunyai kapasiti 1597 cc. Ia dipasangkan dengan 16 injap yang dibangunkan oleh pembuat kereta Malaysia, PROTON. Penyesuai pusar diletakkan di dalam masukan liang enjin. Sudut penyesuai di tetapkan pada 30o untuk memaksa cas supaya melantun kepada dinding liang agar membentuk pusaran. Tujuan tesis ini ditulis adalah untuk mendapatkan kesan pusar ke atas enjin dan membandingkannya dengan proses percampuran gelora normal. Analisis kesan pusaran dilakukan dengan menggunakan GT-SUITE yang mempunyai aliran pusar yang telah dipiawaikan di dalam perisian tersebut. Kesan tersebut disimulasikan menggunakan GT-SUITE dan didapati bahawa pusaran mengakibatkan penggunaan bahan api yang berkurangan dalam enjin dan juga meningkatkan kecekapan isi padu. Keputusan eksperimental menunjukkan kesan pusaran meningkatkan kuasa, daya kilas dalam keadaan melahu dan laju jajap dibandingkan dengan keadaan golakan normal. Walaupun begitu, ia berkurangan secara mendadak semasa pecutan kelajuan. Ini berlaku disebabkan oleh ketakdayaan penyesuai pusar untuk menghasilkan pusaran pada aliran angin halaju semasa keadaan bukaan mendikit luas.

This paper introduces an attempt to enhance the accuracy of panel methods. A low-order panel method is selected and coupled with semi-empirical methods to enhance the accuracy of drag prediction of flying bodies at supersonic speeds. The semi-empirical methods are used to improve the accuracy of drag prediction by mathematical modelling of viscosity, base drag, and drag due to wing-body interference. Both methods were implemented by a computer program and validated against experimental and analytical results. The comparisons show that a considerable improvement has been achieved for the selected panel method for prediction of drag coefficients. In general, accuracy within an average value of -4.4% was obtained for the enhanced panel method. Such accuracy could be considered acceptable for the preliminary design stages of supersonic flying bodies such as projectiles and missiles. The developed computer program gives satisfactory results as long as the considered configurations are slender and the angles of attack are small (below stall angle).  ABSTRAK: Kertas kerja ini memperkenalkan percubaan untuk  mempertingkatkan ketepatan kaedah panel. Kaedah panel tertib rendah telah dipilih dan digabungkan dengan kaedah separa empirik untuk mempertingkatkan ketepatan ramalan seret objek terbang pada kelajuan supersonik. Kaedah semi empirikal yang digunakan untuk meningkatkan ketepatan jangkaan seret menggunakan model matematik bagi kelikatan, seretan dasar, dan  seretan disebabkan  oleh badan sayap interferens. Kedua-dua kaedah dijalankan menggunakan program komputer dan disah berdasarkan keputusan uji kaji dan analisis. Perbandingan keputusan menunjukkan peningkatan yang mendadak diperolehi melalui kaedah panel yang telah dipilih sebagai jangkaan pekali seret. Secara umumnya, ketepatan yang melingkungi nilai purata sebanyak -4.4% telah diperolehi daripada kaedah peningkatan panel. Keputusan sebegini boleh diterima untuk peringkat reka bentuk permulaan bagi objek terbang supersonik seperti projektil dan misil. Program komputer yang direka memberikan keputusan yang memuaskan selagi konfigurasi yang dipilih adalah kecil dan sudut serangan adalah rendah (di bawah sudut tegun).

In this study, sludge palm oil was utilized as a raw material for process optimization in a stirred tank bioreactor for the biosurfactant production. Optimized parameters include temperature, agitation and aeration while the pH and media compositions such as NaNO3, NaCl, FeSO4, Meat extract, and glucose have been fixed from the previous study. The design of this research was made by using the Design-Expert software (2 level factorial design). Surface tension was used as indirect indicator for biosurfactant production. After model validation, yield of biosurfactant was found to be highest when surface tension was at its lowest value (<24 mN/m) at temperature of 300C , agitation 300 rpm and around 0.5 vvm of aeration with percentage error less than 10% between observed value and predicted value. The finding in this research can be applied to produce biosurfactant in large amount from the less expensive material such as sludge palm oil by using the same optimized model equation.ABSTRAK: Dalam kajian ini, enapcemar kelapa sawit digunakan sebagai bahan mentah untuk pengoptimuman proses dalam bioreaktor bagi penghasilan biosurfactant. Parameter yang dioptimumkan termasuk suhu, pergolakan dan pengudaraan manakala pH dan komposisi media seperti NaNO3, NaCl, FeSO4, ekstrak daging, dan glukos telah ditetapkan daripada kajian sebelumnya. Reka bentuk kajian ini telah dilakukan dengan menggunakan perisian Design Expert (2 Level factorial design). Tegangan permukaan digunakan sebagai penunjuk tidak langsung untuk penghasilan biosurfactant. Selepas pengesahan, hasil biosurfactant didapati terbanyak apabila tegangan permukaan pada nilai terendah (<24 mN/m) pada suhu 300C, pergolakan 300 rpm, dan sekitar 0.5 vvm pengudaraan dengan margin perbezaan kurang daripada 10% antara nilai sebenar cerapan dan nilai yang diramalkan. Penemuan dalam kajian ini boleh digunakan untuk menghasilkan biosurfactant dalam jumlah yang besar dari bahan yang murah seperti enapcemar kelapa sawit dengan menggunakan model optimum yang sama.KEY WORDS:  Biosurfactant, Sludge Palm Oil, Process optimization, and Factorial design.
