"In this study, a method was developed for tuning moments of inertia for a free-flying dynamically similar/scaled model of an aircraft. For this method, the simulated annealing optimization algorithm was used to obtain similar mass-inertial properties of the model and the full-scale aircraft utilizing ballast weights. For a scaled model of a Su-27 fighter, the ballast arrangement were designed and weights were determined to achieve the required center of gravity position and the moments of inertia based on the similitude requirements. A computer code was developed, and the task of tuning inertia properties was performed. The results showed that the proposed optimization approach was successfully used to determine a feasible ballast weight and position. Moreover, the ballast weight reduced from 8.66 kg to 4.86 kg using the proposed technique, and the inertia characteristics’ non-similarity was minimized."

"ABSTRAK
Surat Keputusan Rektor Universitas Sriwijaya No. 0307/UN9/DT.SP/2017 menjelaskan bahwa kegiatan perkuliahan dapat dilaksanakan secara e-learning, sebanyak 25% pertemuan. Hal ini dalam rangka mendukung isu strategis pengembangan Unsri menuju tahun 2025 yaitu pemerataan dan perluasan akses pendidikan dan globalisasi dan daya saing. Harapan dari pihak LP3MP selaku pengelola e-learning Unsri adalah setiap proses perkuliahan menggunakan e-learning sebanyak 4 kali pertemuan, namun dari hasil laporan masih ada matakuliah yang tidak menggunakan e-learning pada proses perkuliahan. Berdasarkan analisis fishbone, salah satu permasalahannya adalah kurangnya minat dosen dalam menggunakan e-learning. Untuk meningkatkan target perkuliahan online dapat dilakukan dengan mencari faktor-faktor yang menyebabkan kurangnya minat dosen dalam menggunakan e-learning. Faktor-faktor tersebut dapat dilakukan dengan analisis teori SQB dan menerapkan model penerimaan teknologi UTAUT. Hasil yang diperoleh dalam penelitian ini menjelaskan lack of computer self- efficacy dan lack of organizational support terbukti mendorong terjadinya inertia, sementara lack of individuals experience with computers dan lack of resources tidak terbukti secara signifikan memengaruhi inertia. Inertia terbukti secara negatif memengaruhi behavioural beliefs, sehingga secara tidak langsung menurunkan intensi untuk mengadopsi e-learning. Performance expectancy dan effort expectancy terbukti berpengaruh positif terhadap intensi pengguna.

ABSTRACT
Sriwijaya University Rectors Decree No. 0307/UN9/DT.SP/2017 explains that lecture activities can be implemented in e-learning, as much as 25% of meetings. This is in order to support the strategic issue of Unsri's development towards 2025, namely equity and expansion of education access and globalization and competitiveness. Expectations from the LP3MP as the manager of e-learning Unsri is every lecture process using e-learning as much as 4 times of meetings, but from the report there are still subjects that do not use e-learning in lecturing process. Based on fishbone analysis, one of the problems is lack of interest of lecturer in using e-learning. To improve the target of online lectures can be done by looking for factors that cause the lack of interest of lecturers in using e-learning. These factors can be done by analyzing SQB theory and applying the UTAUT technology acceptance model. The results obtained in this study explain the lack of computer self- efficacy and lack of organizational support proven to encourage inertia, while lack of individuals experience with computers and lack of resources are not proven to significantly affect inertia. Inertia has been shown to negatively affect behavioral beliefs, thus indirectly reducing the intention to adopt e-learning. Performance expectancy and effort expectancy proved to have a positive effect on user intentions."

"[ABSTRAK
Pendahuluan
Hipertensi merupakan masalah kesehatan dunia karena jumlah penderita yang
banyak serta komplikasi yang diakibatkannya. Pengendalian tekanan darah pada
pada pasien hipertensi masih belum adekuat. Penyebab utama kegagalan
pengendalian tekanan darah pada pasien hipertensi adalah ketidak-patuhan berobat,
adanya therapeutic inertia dan penyakit yang resisten.
Tujuan
Mengetahui proporsi therapeutic inertia pada pasien dengan tekanan darah tidak
terkontrol, tingkat medication adherence dan proporsi pengendalian tekanan darah
pada pasien hipertensi yang telah berobat lebih dari enam bulan dengan melakukan
pengisian kuesioner mengenai kepatuhan berobat dan evaluasi dari rekam medis
mengenai tatalaksana hipertensi.
Metode
Telah dilakukan penelitian potong lintang pada bulan April 2015 sampai Mei 2015
terhadap 126 pasien dengan hipertensi dan telah berobat lebih dari enam bulan di
poliklinik Ginjal-Hipertensi RSCM Jakarta-Indonesia. Subjek dilakukan
wawancara terstruktur dan pengukuran tekanan darah dan diminta untuk mengisi
kuesioner 8-item Morisky Medication Adherence Score (MMAS-8) untuk menilai
kepatuhan berobat serta evaluasi rekam medis pasien untuk menilai tatalaksana
hipertensi yang diterima, serta tekanan darah selama berobat.
Hasil
Didapatkan 113 subjek yang sesuai dengan kriteria penelitian. Dari hasil penelitian
didapatkan pengendalian tekanan darah adalah sebesar 69,3% dari seluruh
kunjungan pada pasien dengan tekanan darah tinggi, dari 30,7% pasien dengan
tekanan darah tidak terkontrol, tingkat therapeutic inertia mencapai 84,1%.
Kepatuhan berobat yang baik didapatkan pada 85,8% pasien dengan hipertensi
Simpulan
Tingkat pengendalian tekanan darah pada pasien hipertensi sudah cukup baik.
Kepatuhan berobat pasien dengan hipertensi sudah baik. Tingkat therapeutic
inertia pada pasien hipertensi dengan tekanan darah tidak terkontrol masih tinggi.

uncontrolled blood pressure, medication adherence level and blood pressure
control rate in hypertensive patient who has been on medication for over than six
month by filling questionnaire on medication adherence and evaluation of medical
record on hypertension therapy.
Method
A cross-sectional study was conducted in April 2015 through May 2015 on 126
hypertensive patient and has been on hypertension medication for over than six
month at Nephrology-Hypertension clinic Cipto Mangunkusumo Hospital, Jakarta-
Indonesia. We conducted structured interview and blood pressure measurement to
the subject, and requested to fill 8-item Morisky Medication Adherence Score
(MMAS-8) to evaluate medication adherence and reveiw of medical record to
evaluate hypertension therapy and blood pressure during ambulatory visit.
Results
There were 113 subject that meet the study criteria. The blood pressure control rate
were 69.3% from all visit of hypertensive patient. From 30.7% visit with
uncontrolled blood pressure, therapeutic inertia were 84,1%. Good medication
adherence were found in 85.8% hypertensive patient.
Conclusion
Blood pressure control rate in hypertensive patient is good. Medication adherence
in hypertensive patient were also found good. We found that the theraputic inertia
level among hypertensive patient with uncontrolled blood pressure is high., Background

"Metode kendali vektor telah menjadi alternatif utama dalam pengendalian motor induksi tiga fasa. Salah satu metode kendali vektor yang sering digunakan adalah metode kendali torsi langsung. Namun sistem ini memiliki kekurangan dengan adanya riak pada torsi yang besar. Penambahan duty ratio berbasis logika Fuzzy dapat memberikan unjuk kerja yang lebih baik bila dibandingkan dengan metode kendali torsi langsung konvensional. Dengan melakukan pengujian sistem kendali torsi langsung dan duty ratio dengan motor induksi tiga fasa kapasitas kecil, sedang dan besar, dapat dilihat pengaruh dari momen inersia terhadap putaran rotor. Pada tesis ini digunakan MATLAB SIMULINK untuk simulasi dengan tiga tipe motor, yaitu 1 HP, 10 HP dan 50 HP. Dengan parameter yang sama, dapat terlihat motor dengan nilai momen inersia besar memiliki putaran lebih stabil bila dibandingkan dengan motor yang memiliki momen inersia kecil.

Vector control has become the first alternative in control of three phase inductionmotor. One of the vector control method which is commonly used is a direct torque control method. However, this system has drawback as the existence of ripples at torque. The addition of duty ratio control base on Fuzzy logic can give better performance when compared to conventional direct torque control. By doing an examination on direct torque control and duty ratio with small, medium and big capacities of three phase induction motors can be shown the influence from moment inertia to rotor rotation. This thesis uses MATLAB SIMULINK for the simulation study with three types of motors, for example 1 HP, 10 HP and 50 HP. It is shown that using the same parameters, a motor with a larger moment inertia gives a better performance in comparison to a motor with smaller moment inertia."

"ABSTRAK
Penelitian ini mengembangkan Computer Aided Diagnosis (CAD) untuk mamografi dengan menggunakan metode segmentasi Markov Random Field (MRF) dan local threshold. Metode local threshold mencari abnormalitas dengan membandingkan segmen citra abnormal dengan normal. Sementara itu, metode MRF mencari abnormalitas berdasarkan nilai piksel dan bentuk cluster. Metode MRF dikerjakan dengan dan tanpa median filter, contrast enhancement histeq dan CLAHE. Metode segmentasi local threshold memiliki sensitivitas 77,8%, akurasi 68,4%, spesifitas 60,4%, presisi 62,5%, dan overall error 31,6%. Rendahnya keberhasilan disebabkan bentuk payudara pada data sampel tidak seragam, sehingga tiap segmen dari tiap citra belum tentu menunjukkan posisi yang sama. Segmentasi citra MRF yang dilakukan tanpa filter dan contrast enhancement, memiliki keberhasilan terendah. Hal ini membuktikan bahwa citra mamografi memiliki kontras yang rendah dan noise yang tinggi. Metode MRF dilengkapi dengan median filter memiliki akurasi tertinggi (87,0%) dan overall error terendah (12,8%), yang berarti metode ini adalah metode yang paling baik dalam melakukan deteksi sesuai dengan diagnosis dokter. Metode histeq+MRF memiliki sensitivitas yang tinggi (95,9%) dan spesifitas yang rendah (76,2%) yang menunjukkan bahwa metode ini berhasil mendeteksi citra abnormal sebagai abnormal, namun banyak mendeteksi citra normal sebagai abnormal. Metode CLAHE+MRF memiliki nilai spesifitas tertinggi (92,2%) dan sensitivitas terendah (73,1%) yang berarti metode berhasil mendeteksi citra normal sebagai normal, namun banyak mendeteksi citra abnormal sebagai normal. Dalam menentukan sifat benign dan maglina dari cluster abnormal, metode histeq+MRF merupakan metode yang paling berhasil dalam memvisualisasi citra dengan diagnosis maglina.

ABSTRACT
This research developed Computer Aided Diagnosis (CAD) for mammography using Markov Random Field (MRF) and local thereshold method. The Local thereshold methods finds abnormalities by comparing segments from abnormal image. While, MRF methods find abnormalities based on the pixel value and cluster's shape. In this research, the MRF method carried out with median fiter, histeq, and CHALCE contrast enhancement. MRF without any filter and contrast enhancement also done. The sensitivity, accuracy, specfity, presision and overall error of local thereshold method sequentially are 77.8%, 68.4%, 60.4%, 62.5%, and 31.6%. The low result caused by the diversity of the breast's from in the sample, so that each segment on each image doesn't refer to the same anatomical position. MRF segmentationwithout any filter and contrast enhancement gave the worst result. This result proved that mammography images have poor contrast and lot of noise. MRF method with median filter has the highestaccuracy (87.0%) and the lowest overall error (12.8%). This score shows that median filter + MRF method is the best method that can matches doctor's diagnosis. Histeq+MRF method has the highest sensitivity (95.9%) and the lowest specifity (76.52%). This result indicates that histeq+MRF method succesfully detect abnormal image as abnormal, but detect many the normal images as abnormal. CLAHE+MRF method has the highest specifity (92.2%) and the lowest sensitivity (73.1%). It shows that this method has a good performance in detecting normal image as normal but detect many abnormal images as normal. Histeq+MRF method shows the best performance in visualizing maglina clusters."
