DESIGN SPESIAL MAINTENANCE BANGUNAN DERAH IRIGASI IYAY RILAULAMPUNGSELATAN

The maintenance works of inigation network are needed to maintain irrigation infrastructure to be well functioned and operable. The building shall be defected due to natural causes which would make the dimension to become nonstandard, hence the effort to maintain the Building to be well functioned is needed to be conducted by the government by means of special maintenance. Maintenance shall be categorized into 4 gzpes of activities, i.e. continnous maintenance, periodic maintenance, emergency maintenance and annual maintenance. Building handlings shall not be conducted physically only hence the effort to increase the efftciency by means of operational and maintenance activity and by means of maintenance and upgrading of skill and knowledge of the farmers as water resource users shall be conducted following the physical maintenance, hence the farmers could solve their problem considering water usage management independently. The research is a site research to repair the defected or unserviceable Building as it was expected shall be conducted by the government and the water resource users

PEMODELAN TRANSPOR SEDIMEN PANTAI KUALO KOTA BENGKULU

Provinsi Bengkulu merupakan salah satu daerah dengan pantai terpanjang di Indonesia. Secara umum keadaan pantai di Bengkulu telah banyak mengalami kerusakan berupa abrasi dan sedimentasi. Perubahan garis pantai disebabkan oleh faktor alam dan/atau faktor manusia Secara geografis, Pantai Kualo terletak di bagian Barat Pulau Sumatera yang berhadapan langsung dengan Samudera Hindia. Ini berarti, seluruh tepian barat merupakan daerah laut lepas dengan sedikit pulau yang menghalanginya. Sehingga pada saat nantinya, pihak yang berwenang dapat mempertimbangkan hal-hal yang harus dilakukan dalam menjaga pesisir pantai di Pantai Kualo ini. Berdasarkan hal ini, maka penelitian ini tentang peramalan perubahan garis pantai di Pantai kualo Kota Bengkulu dalam jangka waktu tertentu perlu dilakukan. Tujuan dari penelitian ini yaitu menganalisa besarnya transpor sedimen yang terjadi di Pantai Kualo Bengkulu dan memprediksi perubahan garis pantai dalam jangka waktu 10 tahun di Pantai Kualo Bengkulu. Penelitian ini dilakukan dengan menghitung transpor sedimen yang masuk dan keluar pesisir pantai dengan membagi pantai menjadi 10 sel (pias) sepanjang pantai 500 m dengan panjang 50 m pada setiap sel (pias) ditambah satu pias sebagai titik acuan. Penelitian yang dilakukan menghasilkan besarnya transpor sedimen dan perubahan garis pantai

PENGARUH HUTAN BAKAU TERHADAP SEDIMENTASI

The aim of this research is to contribute in engineering consideration especially to study the ability Rhizophora shrub to increase velocity of sedimentation. The research has done using phsycal modelling (prototype refer to Rhizophora aged 4 – 5 years old). Depht obtained by three time measuring with 10 minutes interval to obtain precision f measurement. Model has scale 1:10 base on facility.The result ofresearch shows that Rhizophora shrub can reduce velocity, the depth raise, and the velocity of sedimentation raise.

PENGARUH NILAI KEKASARAN PERMUKAAN AGREGAT KASAR TERHADAP KUAT TEKAN BETON

The aim of this research was to find out the influence of surface cruduity value of coarse aggregater to pressure strength of concrete. The water ratio that aplicated was 0,5. The percentation of surface cruduity value were 100%, 50%, and 0% of the specimen. 9 cylinders of 150 x 300 mm specimens had been tested. It was showed the surface cruduity value to the concrete cause the strengths gettinglower as the percentation getting smaller (average 12 %)

PREDIKSI PERUBAHAN GARIS PANTAI BENGKULU (STUDI KASUS PANTAI ZAKAT KOTA BENGKULU)

Abstrak: Prediksi Perubahan Garis Pantai Bengkulu (Studi Kasus Pantai Zakat Kota Bengkulu). Kota Bengkulu merupakan daerah pantai yang berpotensi menjadi objek wisata salah satunya Pantai Zakat yang akan menjadi lokasi penelitian. Penelitian ini dimulai pada koordinat 3°47’4,71” Lintang Selatan - 102°15’26,88” Bujur Timur sampai dengan 3°46’38,52” Lintang Selatan - 102°15’43” Bujur Timur bertujuan untuk mengetahui proses perubahan garis pantai, dan proses sedimentasi-abrasi di pantai Zakat Kota Bengkulu. Penelitian ini memprediksi perubahan garis pantai 5 tahun. Prediksi perubahan garis pantai didekati dengan pendekatan model dengan GENESIS (Generalized Model for Simulating Shoreline Change). Hasil penelitian menunjukkan dalam kurun waktu 5 tahun (2020-2025) mengalami abrasi sebesar 2,823 m dan sedimentasi sebesar 1,677 m. Dengan demikian pantai Zakat Kota Bengkulu dalam kurun waktu 5 tahun akan mengalami sedimentasi dan abrasi. Kata kunci : Perubahan Garis Pantai, Sedimentasi, Abrasi, GENESIS Abstract: Prediction of Changes in Bengkulu Beach Line (Case Study Zakat Beach City of Bengkulu City). Bengkulu City is a coastal area that has the potential to become a tourist attraction, one of which is Zakat Beach which will be the study location. This study begins at coordinates 3°47'4,71" S 102°15'26,88" E to 3°46'38,52" S, 102°15'43" E to conducted to find out the process of shoreline change, and the process of sedimentation-abrasion at the Zakat beach of Bengkulu City. This study predicts the shoreline changes over the next 5years. The prediction of shoreline changes is approached with GENESIS (Generalized Model for Simulating Shoreline Change) approach model. The results showed within 5 years (2020-2025) the shoreline will experience abrasion of 2.823 m and sedimentation of 1,677 m. Thus Zakat beach of Bengkulu city in period 5 years will experience abrasion and sedimentation. Key words: Shoreline Change, Sedimentation, Abrasion, GENESI

Kajian Kondisi Jalur Pejalan Kaki di Dalam Kawasan Kampus Universitas Bengkulu

ABSTRAK. Berjalan kaki merupakan kegiatan yang esensial dalam menikmati suatu wilayah sekaligus moda transportasi yang alami dan tanpa emisi. Berdasarkan observasi awal peneliti, ditemukan pada kawasan Universitas Bengkulu tidak tersedia jalur pejalan kaki, jalur pejalan kaki yang terputus, serta  jalur pejalan kaki yang tidak memenuhi standar. Sehingga untuk mewujudkan jalur pejalan kaki yang memenuhi standar dan mendorong aktivitas berjalan kaki di dalam kampus maka dibutuhkan jalur pejalan kaki yang sesuai standar dan walkable. Teknik pengumpulan data dan informasi primer pada penelitian ini meliputi teknik observasi dan kuesioner untuk mengkaji tingkat aktifitas pejalan kaki di kawasan kampus. Berdasarkan penilaian yang telah dilakukan, ditemukan bahwa pada segmen 1 merupakan area dengan kondisi jalur pedestrian yang telah tersedia sesuai standar dan berfungsi dengan baik dan pada segmen 2 merupakan area yang memiliki permasalahan jalur pejalan kaki yang tidak sesuai standar sehingga perlu beberapa solusi yang tepat untuk meningkatkan kondisi jalur pejalan kaki. Kata kunci: Kampus, Observasi, Jalur Pejalan Kaki ABSTRACT. Walking is an essential activity in enjoying an area as well as a mode of transportation that is natural and without emissions. Based on the researchers' preliminary observations, it was found that there were no pedestrian paths in the University of Bengkulu area, broken pedestrian paths, and pedestrian paths that did not meet standards. To realize pedestrian paths that meet the criteria and encourage walking activities on campus, pedestrian paths appropriate to the standard and walkable are needed. This study's primary data and information collection techniques include observation and questionnaire techniques to assess the level of pedestrian activity in the campus area. Based on the assessment that has been done, it was found that in segment 1 is an area with pedestrian track conditions that have been available according to the standard and functioning correctly. Segment 2 is an area with pedestrian path problems that are not following standards, so it needs some appropriate solutions to improve pedestrian path conditions. Keywords: Campus, Observation, Pedestrian Wa
