Abstrak
Kondisi asimetris pada bangunan akan menyebabkan titik berat bangunan tidak berada ditengah bangunan yang menyebabkan terjadinya efek torsi ketika diberi gaya lateral. Salah satu solusi untuk mengurangi efek torsi yaitu dengan pemberian dilatasi. Penelitian ini bertujuan untuk menganalisis perilaku struktur tidak beraturan ber-layout T dengan dilatasi balok kantilever agar dapat diketahui kemungkinan terjadinya pounding, selain itu juga dilakukan desain balok kantilever.
Penelitian ini dilakukan dengan menggunakan bangunan fiktif yang dianalisis dengan menggunakan perangkat lunak. Bangunan yang dianalisis merupakan bangunan 8 tingkat dengan ketinggian 32,5 m. Pada analisis ini digunakan data gempa Time History kota Padang. Analisis dilakukan pada tiga model bangunan. Model kedua dan model ketiga merupakan bentuk terpisah dari bangunan yang utuh, dan model pertama merupakan bentuk utuh dari bangunan ber-layout T.
Hasil analisis yang telah dilakukan didapatkan bahwa perioda fundamental dari struktur model 1 sebesar 1,485 second, perioda fundamental struktur model 2 sebesar 1,396 second, dan perioda fundamental struktur model 3 sebesar 1,490 second yang bisa dilihat dari mode 1. Pola gerak struktur pada mode 1 dan mode 2 di ketiga model tersebut mengalami translasi. Berdasarkan analisis yang telah dilakukan didapatkan hasil bahwa simpangan antar lantai pada setiap model tidak ada yang melebihi batas izin simpangan antar lantai. Bangunan mengalami pounding pada detik ke 21.63, tetapi hal ini dapat diatasi dengan adanya pemisahan struktur (dilatasi). Pemberian jarak dilatasi direncanakan sebesar 70 mm. Desain tulangan untuk balok kantilever 250×500 mm yaitu 3 buah tulangan tarik dan 2 buah tulangan tekan masing-masing dengan diameter tulangan 22 mm.
Kata Kunci : dilatasi, balok kantilever, pounding, simpanga

ZulhamPromotor: Prof. Dr. Said Muhammad, MACo-Promotor: Prof. Dr. Raja Masbar, M.Sc ; Prof. Dr. lic.rer.reg. Sirojuzilam, SEPenelitian ini bertujuan untuk mengkaji dampak otonomi khusus terhadap konvergensi pertumbuhan ekonomi regional di Aceh, serta faktor-faktor yang mempengaruhi konvergensi pertumbuhan ekonomi tersebut sebelum dan sesudah berlakunya otonomi khusus di Provinsi Aceh. Variabel bebas dalam penelitian ini adalah PDRB per kapita awal, penduduk bekerja, penduduk miskin, lama sekolah, usia harapan hidup, pembentukan modal tetap bruto, pendapatan asli daerah, dana perimbangan, dana otonomi khusus, dan total penerimaan. Sedangkan variabel terikat adalah pertumbuhan ekonomi (Barro dan Sala-I-Martin, 1992, 1995, 2004). Data yang digunakan adalah data sekunder bersifat data panel yakni 23 kabupaten/kota di Provinsi Aceh dari tahun 1991 sampai dengan 2012. Model yang digunakan adalah model regresi data panel yang dikelompokkan ke dalam empat bagian analisis yakni sebelum otsus (1991-2001), sesudah otsus (2002-2012), sesudah ada dana otsus (2008-2012), dan periode keseluruhan (1991-2012). Hasil estimasi menunjukkan bahwa terjadi konvergensi sigma pertumbuhan ekonomi regional di Aceh ditandai dengan menurunnya nilai standard deviasi dari 0,7698 sebelum otsus menjadi 0,5411 setelah otsus. Secara absolut, juga terjadi konvergensi pertumbuhan ekonomi regional di Aceh dan signifikan di mana nilai half-life of convergence dengan migas selama 21 tahun, dengan non migas sekitar 27 tahun. Sedangkan speed of convergence sesudah otsus baik migas maupun non migas mengalami kenaikan. Namun, setelah adanya dana otsus, kecepatan konvergensi migas mengalami penurunan, sedangkan non migas mengalami kenaikan. Secara kondisional, tidak terjadi konvergensi pertumbuhan ekonomi regional sesudah ada dana otsus di mana parameter logPDRB per kapita awal bernilai positif 0,3801, P-value 0,2529, t stat 1,1494 < t tab 1,6582. Variabel eksogen yang berpengaruh signifikan hanya pendapatan asli daerah dan lama sekolah. Bahkan, total penerimaan dan dana otsus berhubungan negatif dengan pertumbuhan ekonomi. Keseluruhan periode diperlukan waktu half-life of convergence sekitar 30 tahun dengan speed of convergence rata-rata 2,30 persen per tahun untuk menuju ke arah steady state. Program pembangunan ke depan haruslah berorientasi pada penciptaan lapangan kerja yang banyak, menurunkan jumlah penduduk miskin secara signifikan, peningkatan harapan hidup yang tinggi, dan meningkatkan lama sekolah penduduk ke jenjang yang lebih tinggi, serta pemanfaatan dan pengelolaan dana otsus yang terbaik, sehingga pertumbuhan ekonomi regional Aceh meningkat sekaligus terjadi kecepatan konvergensi dan pengurangan disparitas pembangunan antar daerah di Aceh.Kata Kunci: Konvergensi, Speed of Convergence, Half-life of Convergence, Otonomi Khusus, Pertumbuhan Ekonomi Regiona
Deteksi Gen COL2A1 dan SLITRK1 Menggunakan DNA Preservasi Asal Saliva Manusia yang Diberikan Kombinasi Antimikroba dan Penghambat Dnase
No full textBackgrounds. The use of DNA is important in many fields. DNA is often obtained from blood samples. Compared to blood, saliva has several advantages. In saliva, DNase and microorganisms capable of degrading DNA are present. DNA preservation in saliva requires a combination method of antibiotics that can be bactericidal while inhibiting DNase activity. Detection of genes encoding proteins, namely COL2A1 and SLITRK1, can prove the success of the preservation of the human genome from saliva. Aims. This research aims to determine the role of a combination of antibiotics and DNase inhibitors to preserve DNA from human saliva by detecting COL2A1 and SLITRK1 genes. Methods. This was a purely pilot experimental study. Saliva samples were collected from 10 subjects and divided into no-treatment (NT) and treatment (T) groups. The NT group was not given anything. Group T was supplemented with gentamicin sulfate, clindamycin, ketoconazole, and EDTA. Blood samples served as positive controls. Salivary DNA was extracted using the spin column method on days 0, 3, 7, 10, and 14 of storage at room temperature. DNA purity and concentration were measured using a nanophotometer. COL2A1 and SLITRK1 genes were detected using the polymerase chain reaction method and then visualized using 1% agarose gel electrophoresis. Results. The average concentration of DNA obtained from the extraction was 29.40 ng/μL and the average purity was 1.70. The PCR results of the NT group showed more multiple bands, smears, and undetectable genes. Meanwhile, more target gene bands were detected in group T. Conclusions. The use of a combination of antimicrobials and DNase inhibitors can be a method to preserve DNA in closed containers at room temperature for up to 14 days.88 HalamanSkripsi Sarjan

The Correlation Between Plasma Epstein-Barr Virus DNA Levels and DNA Methyltransferase in First-Degree Relatives of Nasopharyngeal Carcinoma Patients in North Sumatra
No full textBackground: Nasopharyngeal carcinoma (NPC) is highly prevalent in Southeast Asia. It is often diagnosed at an advanced stage, which necessitates screening in high-risk populations. The interaction between the Epstein-Barr virus (EBV) and the host's epigenetic response plays a role in identifying suitable screening methods.
Objective: This study aims to evaluate the differences in plasma EBV DNA and DNA methyltransferase-1 (DNMT-1) levels, as well as to analyse the correlation between EBV DNA and DNMT-1 levels in NPC patients and their first-degree relatives.
Methods: A cross-sectional study was conducted involving 25 NPC patients and 25 first-degree relatives of NPC patients. EBV DNA and DNMT-1 levels were measured using qRT-PCR. Differences in EBV DNA and DNMT-1 levels between NPC patients and their first-degree relatives were analysed using the independent samples t-test and the Mann-Whitney test. The correlation between EBV DNA and DNMT-1 was assessed using the Spearman correlation test.
Results: The median, minimum, and maximum values of DNMT-1 relative expression and EBV DNA relative quantity were higher in NPC patients compared to their first-degree relatives. The difference in the relative quantity of EBV DNA was statistically significant (p 0.05). Additionally, there was no significant correlation between the relative quantity of EBV DNA and the relative expression of DNMT-1 in NPC patients and their first-degree relatives (p > 0.05).
Conclusions: There are notable differences in plasma EBV DNA levels between NPC patients and their first-degree relatives, suggesting the potential use of EBV DNA as a disease marker in NPC patients and a risk marker for NPC in first-degree relatives in North Sumatra. However, plasma EBV DNA levels are not correlated with DNMT-1 levels in NPC patients and their first-degree relatives.117 PagesTesis Magiste
