Peningkatan Kestabilan Quadrotor menggunakan Kendali Linear Quadratic Regulator dengan Kompensasi Integrator dalam Mempertahankan Posisi
The quadrotor's ability to maintain position is a major requirement for the completion of various current missions. However, the large steady-state error (SSE) and multiple overshoots due to environmental disturbances cause flight instability. This condition makes Quadrotor unable to complete the mission optimally. Therefore, in this study applying a linear quadratic regulator control method, this research contributes to the addition of integrator compensation in handling the translational movement of the quadrotor. System model design testing is carried out by comparing quadrotor control using the LQR method without an Integrator and LQR with an Integrator. The value of R=1 for all states and Q_x=0.87, Q_y=124.6, Q_(v_x)=1.77, Q_(v_y)=124.6 and Ki_x=0,004, Ki_y=0.002 makes the SSE tendency that occurs 0.10 meters for the x-axis and -0.28 for the y-axis, while the multi-overshoot that occurs is 0.41 m for the maximum deviation and -1.35 m for the minimum deviation on the x-axis and 0.40 m maximum deviation and 0.47 m minimum deviations on the y axis. The test results show that the LQR control method with Integrator compensation is able to minimize and improve SSE and multiple overshoots that occur in quadrotor flights. In addition, it is able to significantly increase accuracy to 100% from 71.38% and precision to 37.71% from 35.91%.Kemampuan quadrotor dalam mempertahankan posisi menjadi kebutuhan utama untuk penyelesaian berbagai misi saat ini. Namun, besarnya steady state error (SSE) dan multiple overshoot karena gangguan lingkungan menyebabkan ketidakstabilan gerak terbang. Kondisi tersebut menjadikan quadrotor tidak mampu menyelesaikan misi secara optimal. Maka dari itu, pada penelitian ini menerapkan sebuah metode kendali Linear Quadratic Regulator penelitian ini memiliki kontribusi dengan penambahan kompensasi Integrator dalam menangani pergerakan translasi quadrotor. Pengujian desain model sistem, dilakukan dengan membandingkan antara pengendalian quadrotor menggunakan metode LQR tanpa Integrator dan LQR dengan Integrator. Nilai R=1 untuk semua state serta Q_x=0,87; Q_y=124,6; Q_(v_x)=1,77; Q_(v_y)=124,6 dan Ki_x=0,004; Ki_y=0,002 menjadikan kecenderungan SSE yang terjadi sebesar 0,10 m untuk sumbu x dan -0,28 m untuk sumbu y, sedangkan multi overshoot yang terjadi sebesar 0,41 meter simpangan maksimal dan -1,35 m simpangan minimal pada sumbu x serta 0,40 m simpangan maksimal dan 0,47 meter simpangan minimal pada sumbu y. Hasil pengujian tersebut menunjukkan bahwa metode LQR dengan kompensasi Integrator mampu meminimalkan dan memperbaiki SSE maupun multiple overshoot yang terjadi pada penerbangan quadrotor. Selain itu juga mampu meningkatkan akurasi secara signifikan sebesar 100% dari 71,38% serta presisi sebesar 37,71% dari 35,91%
Quadrotor Altitude Control using Recurrent Neural Network PID
The quadrotor is one type of Unmanned Aerial Vehicle (UAV) or unmanned flying vehicle. Quadrotor can be operated by a remote controller or autonomously. Quadrotor control is a challenging problem because it takes into account complex things such as parametric uncertainty, external disturbances, and so on. At the spatial level, three linear degrees of freedom along three axes and three degrees of freedom rotating along three axes are used for the control of a quadrotor. Conventional controls for quadrotors are widely used such as PID, state feedback, and so on. However, because the control is linear, non-linear control has begun to be developed. Some of these controls, for example, use a sliding mode control system, fuzzy methods, and controls by combining linear control with artificial intelligence. This paper will use PID control and an artificial neural network for the quadrotor direction control system. The results of this control test indicate that the combination of PID and RNN on the directional control shows a better response than conventional PID

Deixis or direct appointment is included in the realm of pragmatic studies. Pragmatics is classified into four namely Deixis, conversational implicature, pranggapan, and also Speech Acts (Levinson, 2003). Deixis one of them can be found on the lyrics of the song. This study focused on the deixical analysis of Yvonne Catterfeld's song lyrics. The purpose of Deixis analysis is to describe the meaning of reference. In this study the theory of George Yule (2006) was used to analyze data in the form of 3 lyrics of the song Yvonne Catterfeld entitled âNeben dir, Die Zeit ist reif, and Sonnenscheinâ. This study includes a type of qualitative research that raises descriptive data in the form of words. Data collection conducted in this study using the technique of SBLC (Simak Bebas Libat Cakap) and note-taking techniques. The results obtained from this descriptive qualitative research in the form of a description of Deixis (persona and time) and the meaning of reference. Based on data analysis, it was found that the type of singular first persona Deixis in the lyrics of the song âDie Zeit ist Reif and Sonnenscheinâ both refers to the speaker, while the plural persona Deixis in the lyrics of the song âNeben dirâ refers to the speaker and his partner. Furthermore, the second single persona deiksis on the lyrics of the songâ Die Zeit ist Reif and Sonnenschein " the reference refers to the closest person to the speaker as a speech opponent. The third persona Deixis in the lyrics of the song "Sonnenschein" refers to a noun pronoun and in the lyrics of the song "Die Zeit ist Reif" refers to the family of a close friend of the speaker as a speech opponent. Deixis time is also found in the lyrics of the song "Die Zeit ist Reif and Sonnenschein" found data in the form of the use of the words âjetztâ, âDieser Tagâ, âheutâ, and âirgendwannâ

INCORPORATING COMPLEX SURVEY DESIGN FOR ANALYSING THE DETERMINANT OF WOMEN IN REPRODUCTIVE AGE PARTICIPATION IN FAMILY PLANNING PROGRAM IN INDONESIA
Data generated from complex survey are often treated as un-weighted simple random samples by analyst. This is unfortunate because everyone has different probability to be selected as sample in each stage of the complex survey design. Fail taking it into account will have serious impact in parameter and variance estimation. This paper aims to examining relationship between participation in family planning program and socio demographic status of women in reproductive age in Indonesia used data from latest Indonesianâs Demographic and Health Survey (IDHS). IDHS employs a multi stage stratified sampling design, thus there are a number of weights included in public-use IDHS datasets to account for this complex sample design. We found that the complex design features of the IHDS increased the variance estimates of the estimated parameters in the logistic regression models by about 1.325 â 1.88 times, compared to a simple random sampling. Therefore, using variance estimated from un-weighted simple random samples would lead to wrong conclusion of the significance parameter suggested by the model. The result also found that all of socio demographics variables used as predictors are significant. Thus, women with moderate education, unemployment, exposed by media, living in rural community and wealthy, have spouse that have moderate education and have a job tend to participate in family planning program
