Abstract

Gradasi aktual LPA setelah dipadatkan akan bergeser keluar melampaui batas atas spesifikasi sebagai pengaruh terhadap perbedaan nilai abrasi. Sehingga perlu didesain campuran gradasi di bawah batas bawah spesifikasi agar setelah pemadatan diharapkan gradasi akan bergeser masuk ke dalam spesifikasi. Material yang digunakan adalah LPA dari lokasi Gunung Kayangan dan Katunun, Kalimantan Selatan yang telah dipadatkan sesuai OMC. Dengan berbagai macam variasi gradasi campuran yang mengacu pada Spesifikasi Bina Marga 2010 revisi ke-3. Metode yang digunakan adalah uji permeabilitas skala laboratorium dengan arah pengaliran horisontal menggunakan alat fabrikasi yang terkalibrasi melalui sampel pasir. Uji analisa saringan dilakukan setelah proses pemadatan dan uji permeabilitas dilakukan agar dapat diketahui ukuran aktual butiran setelah dipadatkan. Persamaan y=0,00018x2 ? 0,02674x + 0,95229 dapat digunakan untuk desain di bawah dari batas bawah spesifikasi. Gradasi butiran yang terpotong pada saringan No. 40 cenderung mempunyai nilai koefisien permeabilitas yang besar yakni 5,52 x 10-2cm/det. Pada penerapan di lapangan, dengan memberikan kemiringan permukaan LPA = 3% pada badan jalan kelas I dengan lebar 7 m dan panjang lintasan pengaliran 3,5 m, maka air yang menggenangi jalan akan hilang dalam waktu 2,45 hari. Menurut AASHTO (1993) drainase termasuk ke dalam kategori drainase dengan kualitas baik menuju sedang.Kata kunci: pondasi agregat Kelas A (LPA), permeabilitas horisontal, variasi gradasi, abrasi.

Abstract

In the current era of globalization, government agencies in general operate their management using a computerized system. The system is a collection of elements / elements that are interrelated and influence each other in carrying out joint activities to achieve a goal. The system is very necessary in an organization or company, or service. The smooth running of government and development is very dependent on the performance of the state apparatus, especially the Civil Servants as development planners and implementers. In completing various tasks and responsibilities that constitute an effort to carry out the duties of the Civil Servant, the employee needs to be fostered as well as possible. Performance appraisal is known by the term performance rating, performance appraisal, personnel assessment, employee evaluation is an evaluation activity carried out by the Office or company on employee work performance. Employees are people who are employed in a particular body, both in government institutions and in business entities. An employee appraisal method, namely management by objectives, is a process of approval of objectives within an organization so that management and employees approve these objectives and understand what their position is in the organization.

Abstract

Background: Previously has been defined that peptic ulcer has strongly correlated to Helicobacter pylori (H. pylori) infection. But it hasn’t determined about correlation of gastrin serum level to the ulcer severity on H. pylori infection. The aims of this study were to find the percentage of H. pylori infection on peptic ulcer cases and its correlation to the gastrin serum level. Method: This is analytic cross sectional study in 50 patients with gastric ulcer who came to Adam Malik hospital from February to October 2007. The correlation between gastrin serum level and the size of ulcer with positive and negative Urea Breath Test (UBT) group was analyzed by unpaired student t- test. The correlation between gastrin serum level and ulcer size were investigated with Pearson correlation test and linier regression. Result: Fifty eligible patients, 33 (66%) had positive UBT and 17 (34%) were negative. There were statistically significant difference on gastrin serum level in positive UBT and negative respectively (p = 0.017). There were also significant difference between mean of ulcer size in positive UBT and negative respectively (p = 0.025). There were correlation between gastrin serum level and ulcer size (r = 0.315; p = 0.026). It can predict the increasing ulcer size in 0.012 mm every 1 pg/mL of gastrin serum elevated. Conclusion: Patients with positive UBT has greater ulcer size and higher gastrin level as compared to the negative group. There were positive correlation between gastrin serum level to the size of ulcer in peptic ulcer patients and increase of ulcer size followed with elevated of gastrin serum level. Keywords: Helicobacter pylori infection, gastrin serum level, ulcer size

Abstract

In geotechnical constructions incorporating geomembranes and geotextiles, the interfacestrength of the twogeo!>ynthetics is of the most concern. Some researchers found considerably low values of the strength from variousdevices. This research aimed at contributing the interface strength database with a ring shear device for simulatinglarge displacements commonly mobilised in thefield when failures occur. The interfacing geomembranes were VLDPE,smooth HDPE, PVC, and textured HDPE. Values of ?residuatfor the geomembrane-geotextile interfaces were found tobe independent of stress level. They vary widely from 6.1°to 33.8°, and are controlled mainly by the te,tture andstiffness of geomembranes, and the types and arrangement off ilaments composing the geotextile. The lower value is fora smooth HDPE with a geotextile comprising glossier filaments, while the higher value is mobilised by the texturedHDP E against a geotextile with filaments that are best-interwoven. Of all interface combinations, the ring shear testswith a smooth HDPE geomembrane always resulted in lowest residual interface strengths.

Abstract

Indonesia adalah negara yang berdasarkan atas hukum oleh karena itu sudah sepantasnya selalu menjunjung tinggi keadilan dan ketertiban dalam kehidupan berbangsa dan bernegara. Untuk mencapai hal tersebut diperlukan suatu aturan-aturan atau ketentuan-ketentuan yang dibuat oleh penguasa berwenang  dengan tujuan untuk mengatur, melindungi, menjaga dan memelihara kehidupan warga negaranya. Pelanggaran terhadap aturan-aturan atau ketenuan itu, maka sudah barang tentu penyelesaiannya adalah berdasarkan hukum-hukum positif yang telah dibuat. Hukum positif itu sendiri adalah hukum yang berlaku sebagai hukum bagi masyarakat pada suatu waktu dan tempat tertentu. Sebagai sumber dari hukum positif pada umumnya adalah undang-undang, kebiasaan, ilmu pengetahuan hukum dan jurisprudensi.Hukum dari bermacam-macam jenisnya, salah satu diantaranya adalah hukum pidana. Dalam ruang lingkup hukum pidana yang luas, baik hukum pidana substantif (materil) maupun hukum acara pidana (hukum pidana formil) disebut hukum pidana. Hukum acara pidana sendiri berfungsi untuk menjalankan hukum pidana substantif (materil), sehingga disebut hukum pidana formil atau hukum acara pidana. Tujuan dari hukum acara pidana adalah untuk mencari dan mendapatkan kebenaran materil atau setidak-tidaknya mendekati, ialah kebenaran yang sebenar-benarnya dari suatu perkara pidana dengan menerapkan ketentuan hukum acara pidana secara jujur dan tepat dengan tujuan mencari siapakah pelaku yang dapat didakwakan melakukan pelangaran hukum,dan selanjutnya meminta pemeriksaan dan putusan dari pengadilan guna menemukan apakah terbukti bahwa suatu tindak pidana telah dilakukan dan apakah orang yang didakwa itu dapat dipersalahkan
