Pajanan Kebisingan dan Hipertensi di Kalangan Pekerja Pelabuhan

Penyakit kardiovaskular menempati urutan ke-4 atau 15% dari penyebab kematian yang berhubungan dengan pekerjaan. Hipertensi yang merupakan salah satu penyakit pembuluh darah, dikenal sebagai silent killer karena sering tidak menimbulkan gejala. Sebagian besar penderita hipertensi di Indonesia tidak terdeteksi, sementara mereka yang terdeteksi umumnya tidak menyadari kondisi penyakitnya dan hanya sebagian kecil yang berobat secara teratur. Tujuan penelitian ini untuk mengetahui prevalensi hipertensi pada pekerja pelabuhan di wilayah kerja Kantor Kesehatan Pelabuhan Kelas II Tarakan serta faktor-faktor risiko yang berpengaruh. Desain penelitian yang digunakan adalah potong lintang; subjek diperoleh dari hasil survei penyakit tidak menular tahun 2011 oleh Kantor Kesehatan Pelabuhan Tarakan. Subjek yang terkumpul adalah 361 pekerja. Nilai pengukuran tekanan darah menggunakan nilai baku dari JNC VII tahun 2003. Prevalensi hipertensi ditemukan lebih rendah daripada angka nasional dan provinsi, yaitu 21,88%. Pajanan kebisingan dikaitkan dengan usia, riwayat keluarga hipertensi, stres, indeks massa tubuh dan berhubungan dengan hipertensi.Cardiovascular disease range ranks fourth or 15 % of the causes of death related to job. Hipertension is one of cardiovascular disease thet is known as silent killer because of lack of simptom. Most of hypertension patients in Indonesia are not detected, while they are whose detected do not conscious their disease condition and only little who get the treatment regularly. The objective of this study was to know the prevalence and risk factors of hypertension among harbor worker at Port Health Office Class II of Tarakan with it's associated risk factors. The study design used was crosssectional. The study used secondary data source of noncommunicable disease survey, 2011 at Port Health Office of Tarakan. The subjects were 361 workers. Value of blood pressure measurement using the raw value of the JNC VII IN 2003. The prevalence of hypertension were found lower than national and province indicator score, 21,88%. Noise exposure is associated with hypertension together with age, family hypertension history, stress, body mass index

Pengaruh Suhu Pemadatan Campuran Untuk Perkerasan Lapis Antara (AC-BC)

The main objective of this study was to determine the influence of variations of temperaturechanges on the asphalt compaction process heat (hot mix asphalt) layer between (AC - BC)against Marshall parameter with reference to the specifications of Highways in 2010.Based on the analysis of data processing obtained that the value content of asphalt used formiddle limit is 6.1 % and the lower limit of 6.85 %.Based on the analysis of data processing obtained that the value content of asphalt used formiddle limit is 6.1 % and the lower limit of 6.85 %. From the test results Marshall at atemperature of 135oC, 145oC and 155oC in the middle limit has met all the parameters Marshall.Only at a temperature of 125oC and 115oC that do not meet the parameters Marshall Void in valuedue Mix (VIM) and the Marshall Quotient (MQ) do not enter Specifications Highways Marshall2010. While testing the lower limit on the temperature 115oC, 125oC and 135oC does not meet allthe parameters Marshall, because the value of Marshall Quotient (MQ) did not enter thespecifications of Highways in 2010

Pengaruh Suhu Tumbukan Pada Campuran Aspal Beton Dengan Jenis Lapis AC-WC Gradasi Halus

This study was conducted to determine the effect of temperature on the Marshall parameterscompaction to mix AC - WC subtle gradations central limit. Optimum Asphalt Content Value(KAO) in the study sought to use 15 samples and done in the laboratory of Highway University ofLampung. From the analysis of the Marshall parameters obtained KAO mixture is 5.7%. Marshallparameter data retrieval is done twice trials, each experiment using 2x24 samples with the sametreatment for each experiment. Compaction temperature is 120 o C-155 o C is reviewed by varasi5 o C.From the results of experiments that have been conducted, Marshall parameter valuesobtained in experiment 1 and experiment 2 is not too much different. In general, the Stability,Flow, VMA and VFA qualify specifications bina marga 2010, the MQ does not meet thespecifications of 135 o C or lower temperatures and VIM value does not meet the specifications of130 o C or lower temperatures.Based on the tendency of marshall parameter values obtained fromexperiment 1 and experiment 2 indicate that the data obtained from these experiments hasparticularly a small false possibility

Aspal Modifikasi Dengan Penambahan Plastik Low Liniear Density Poly Ethylene (LLDPE) Ditinjau Dari Karakteristik Masrhall Dan Uji Penetrasi Pada Lapisan Aspal Beton (AC-BC)

This reseach was conducted by reviewing the impact of the addution of plastic plastik low linear density poly ethylene (LLDPE) in a mixturu of AC-BC layer. Next, calculate the optimum bitumen content and continued with the manufacture of test specimens to determine the optimum levels af- ter the analysis process by perfoming the process measuring, weighing, and testing with marshall. From the results of analysis obtained value of the optimum bitumen content that meets the sixth requisite criteria for the mixture according to the specification of Bina Marga 2010 revision III. After that followed the variation with the addition of plastic low linear density poly ethylene (LLDPE) with levels of pesecnt 1%, 3%, 5%, 7%, 9% calculate on the weight of the asphalt. From the analysis of the test reselt, the velue of the stability of the increasing levels of LLDPE in in - creasing the value of stability. But in value VIM no specifications that meet the standarts of Bina Marga 2010 revision III. The Velues decreased penetration of asphalt mix

Perubahan Parameter Parameter Marshal Akibat Perbedaan Jumlah Tumbukan Pada Aspal Concrete – Wearing Course (ACWC) Gradasi Halus

This study was conducted to see the changes in the value of the parameter values marshall afterthe number of collisions in the standards vary the amount of the collision then analyzed thenumber of collision and then analyzed the number of collisions are most effective assessed on thevalue of the characteristic marshall. In the Marshall planning standard for the number ofcollisions of heavy traffic conditions compaction test specimen as 2x75 collision with a mixturecavity boundary between 3.5-5%.This study uses gradation Asphalt Concrete - Wearing Course (AC-WC) smooth gradations formiddle and upper limits. From the data obtained aggregate gradation and asphalt aggregatedemand needs are used to find the optimum bitumen content that is used in the manufacture of testspecimens for variations in the number of collisions is 2x55, 2x65, 2x75, 2x85, and 2x95. Marshallthen test to see the number of collisions are most effective against the characteristics of asphaltmixture.Based on the analysis of the data processing is obtained that the value content of asphalt is used tolimit the middle that is 5.7% and the upper limit of 6.5%. Total Collision 2x75 and 2x85 that meetsall the parameters marshall. For the number of collisions 2x55 and 2x65 obtained small stability,voids In The Mix (VIM) is great and does not make the specification, to the number of collisions2x95, obtained great stability and voids In The Mix (VIM) is small and does not get in thespecification
