`STILISTIKA, RETORIKA DAN PEMBANGUNAN
Get PDFManusia pemakai bahasa merupakan ciptaan Tuhan yang paling sempurna. Kesempurnaannya justru karena manusia secara eksistensial bersifat labil. Ia selalu mempersoalkan adanya. Ia tidak pernah menganggap bahwa sesuatu bersifat final. Daur kehidupan manusia selalu berada dalam proses menjadi. Tidak pernah jadi-jadi. Oleh karenanya manusia berperadaban. Pertanyaannya, jika eksistensi manusia bersifat labil dengan ciri seperti tersebut maka apa dan bagaimana implikasinya terhadap pemakaian bahasa (stilistika dan retorika) dalam konteks pembangunan?Ada dua kerangka berfikir yang akan dipakai untuk menjawab pertanyaan tersebut. Pertama, empirisme-positivisme memosisikan bahasa hanyalah representasi realitas, mirror of reality karena realitas dan kebenaran dianggap riil-faktual atau alamiah-objektif. Dengan logika berfikir tersebut maka orientasi pemakaian bahasa lebih ke arah kategori benar atau salah dan baik atau buruk. Logika berfikir ini akan memberi peluang untuk dimanfaatkan kelompok atau golongan tertentu yang secara politik dan ekonomi dominan untuk menghegemoni.Kedua, logika berfikir kaum fenomenologis dan kritis. Realitas, makna, dan dunia menurut mereka hanyalah ada dalam kata atau bahasa. Dunia dalam kata atau bahasa tersebut hanyalah hasil berduel (retorika) dan konstruksi sejarah yang masih bersifat semu dan labil. Pertarungan atau duel itu merupakan konsekuensi logis bahwa realitas itu ada apabila sudah dalam bahasa. Bahasa sebagai sekretaris sang ada. Logika berfikir ini dapat bernilai positif-produktif karena dapat memberi peluang kepada manusia, masyarakat, dan bangsa yang sedang membangun untuk terhindar dari praktik-praktik sosial, politik, ekonomi, dan budaya yang bernuansa otoritarian-hegemonik
The Use of Box Culvert Precast as a Main Bridge Structure in Arterial Highway Road: An Analysis Study
Get PDFA bridge is a construction that connect two parts of the road cuts off by both natural and artificial obstacles. Meanwhile, a box culvert is a rectangular precast concrete structure that has a basic function as underground construction in the form of culverts, drains, and other supporting constructions. Those function of the box culvert is now developing as the main structure in the construction of bridges and highways. Thus, a research and evaluation should be done. The performance of the existing box culvert structures is in accordance with SNI 1725: 2016 regulations. The research methodology is done by manual calculation to get the load and reinforcement needs, while for static analysis by modelling the structure in SAP 2000 V.14.2.5 program. The material used is the existing material for top-bottom box culvert type (4000 x 4000 x 1500) fc '= 30 MPa and fy = 400 MPa. The results shows the reinforcement does not meet the minimum requirements of strong box structure reinforcement against bridge construction loads. The reinforcement ratio in plate slab area are almost close to the maximum ratio of reinforcement requirements. Whereas in the box culvert wall area, there is an over-reinforcement so the dimensions must be increased

Effect of Volume Fraction Filler on Sound Insulation in Oil Palm Fronds Fiber Composite Polyester Matrix
Get PDFIn this study, the effect of adding palm fiber rods to the polyester matrix for sound insulation purposes was investigated. The type of fiber used is short fibers with random orientation with the percentage difference in the amount of fiber in the composite as a comparison. Testing loss of voice transmission using impedance tube method is done to know the ability of material to reduce or prevent sound. The data obtained from the TL test results were analyzed and the STC (sound transmission class) values were calculated on each sample. The best results obtained are in the first and second samples with the percentage of fiber 0% and fiber 30%. The calculated results of the STC values in samples one and two each have 32.1 dB and 31.6 dB which indicates sufficient ability to defeat the loud noise. Based on these results, a composite with a 30% fiber content can be used as a sound insulation material and can reduce waste of palm oil that is underutilized

Get PDFPengembangan fasilitas bangunan laut seperti platform, subsea pipeline, subsea cable, maupun mini FLNG di wilayah perairan di teluk Bintuni mengakibatkan penyempitan area olah gerak kapal-kapal yang beroperasi di wilayah tersebut. Pengembangan infrastruktur tersebut juga berpengaruh terhadap meningkatnya lalu lintas kunjungan kapal. Hal ini dapat berdampak pada peningkatan resiko tabrakan, baik tabrakan antar kapal, tabrakan antara kapal dengan platform, maupun kemungkinan terjadi kapal kandas. Untuk itu, pada studi ini dilakukan Kajian Traffic Separation Scheme (TSS), dengan tiga alternatif desain shipping lane. Kajian ini menekankan pada perbandingan tingkat resiko kecelakaan yang terjadi pada masing-masing desain shipping lane, serta mitigasi yang direkomendasika
Delays in Construction Project : A Review
Get PDFDelays in construction projects schedule is one of the most noticed problems. Delays may be caused by several project parties and further categorized into excusable non-compensable delays (EN) caused by many factors beyond parties’ control, excusable-compensable delays (EC) caused by the owner, and non-compensable delays (NE) caused by the contractor. Another issue is concurrency in delays. The result of concurrent delay often leads the project parties into complicated situations. Thus, understanding the causes and identifying the types of delays are essential to be done before executing the delay analysis methods in order to allocating the liability of each party. This study concludes that some existed schedule delay analysis methods produce different results, therefore, the practitioners or schedule delay analyst should understand the anticipated results that can be accepted by all construction projects parties
