Abstract

Bricks are a building material that has long been known and used by people in both rural and urban areas and has the same function, namely as a construction material. Bricks are used for civil engineering applications such as walls and residential buildings, fences and also channels. Bricks are made from clay which are made using a simple mold made of wood. After being molded, the bricks are dried in the sun to dry. Once dry, the bricks are arranged neatly and burned at a fairly high fire temperature. This burning process can cause the bricks to become hard. This research was carried out to determine the quality of bricks in two villages, namely Hatu village and Laha village using physical and mechanical properties testing on printed brick samples. Based on the results of testing the physical properties in Hatu village, it was found that the specific gravity was 1.596, the bulk density was 14.7 gr, the porosity was 37.8% and in the Laha village the specific gravity was 1.811, 13.6 gr and 42.4%. Meanwhile, the mechanical test results for the bottom sample in Hatu village were 27.31 kg/cm2 and the bottom sample was 40.10 kg/cm2 and the results in the bottom sample village were 19.16 kg/cm2 and the results for the top sample were 18.02 kg/cm2.

Abstract

Roads are one element of land transportation which is intended to facilitate the movement of people or goods. If road damage occurs it can have an impact on social conditions, especially land transportation facilities. Many causes of road damage are caused by vehicle loads and vehicle volumes which continue to increase beyond road capacity.   The aim of this research is to determine the types of damage that occur on these road sections, such as potholes, longitudinal cracks, collapse, patching, and loose grain which is damage to the Jendral Sudirman road, Ambon City. Based on the level of damage or the condition of the road that has deteriorated, road damage will be handled according to the PCI method according to the level of road damage on the Jendral Sudirman road section, Ambon City.From the results of calculating the condition of the road pavement on Jalan Jendral Sudirman, Ambon City, a rating of 65% was obtained with the condition (Fair).

Abstract

Pegs are a connecting tool in wood construction that is used as the main material to connect wooden beams with one another wooden beam so that they can be strengthened and united. One of the woods that will be made pegs is merbau wood which is found in Maluku. The research method used is an experimental method carried out through an experiment to obtain information on an object of research. This research was conducted at the Laboratory of the Department of Civil Engineering of Ambon State Polytechnic. The number of specimens used is 9 pieces with a peg diameter of 15 mm and variations in pedestal widths of 20 mm, 30 mm and 40 mm totaling 3 pieces each. Of the three variations of test specimens, there is an average maximum load on each test specimen, namely for a 20 mm pedestal of 15000 N, test specimen 2, a 30 mm pedestal of 16500 N and test specimen 3, a 40 mm pedestal of 17166.67 N and the average shear strength produced is, 42.46 Mpa at a pedestal thickness of 20 mm, 46.71 Mpa for wood thickness of 30 mm,  and 48.59 Mpa for 40 mm wood thickness.

Abstract

Bridges are a means of transportation that have a significant role in the smooth traffic movement. Where the function of a bridge is to connect transportation routes that are separated by rivers, swamps, lakes, straits, canals, highways and other crossings. Because the role of bridges is very important, it is necessary to evaluate the feasibility of the bridge. This research aims to analyze the damage level to the Wai Pohon Pule I and Wai Pohon Pule II Bridges in Ambon City based on the standard Bridge Management System (BMS) assessment. From the research results, there was damage to the Wai Pohon Pule I Bridge and the Wai Pohon Pule II Bridge with the condition values ​​of the bridges being as follows, the Wai Pohon Pule I Bridge with the condition value of the bridge being 3 (Damage that requires immediate action), the Wai Pohon Pule Bridge II with the condition value of the bridge being 3 (Damage that requires immediate action).

Abstract

Peningkatan jumlah kendaraan bermotor di Kota Ambon tidak sebanding dengan kapasitas infrakstruktur jalan yang tersedia, sehingga menimbulkan permasalahan kemacetan, terutama pada ruas Jalan Ir. M. Putuhena. Penelitian ini bertujuan untuk menganalisis pengaruh volume kendaraan terhadap kapasitas serta menentukan tingkat pelayanan jalan tersebut. Metode yang digunakan ialah pendekatan deskriptif kuantitatif berdasarkan Manual Kapasitas Jalan Indonesia (MKJI, 1997). Data primer diperoleh melalui survei volume lalu lintas selama tiga periode waktu pengamatan, yaitu pagi (08.00 – 10.00), siang (11.00 – 13.00), dan sore (16.00 – 18.00). Data kemudian dianalisis untuk menghitung volume lalu lintas dalam satuan mobil penumpang (smp/jam), kapasitas jalan, dan derajat kejenuhan (DS). Hasil analisis menunjukkan bahwa volume lalu lintas tertinggi terjadi pada jam puncak sore hari sebesar 1810 smp/jam, dengan kapasitas jalan 3008 smp/jam dan derajat kejenuhan 0,60. Nilai tersebut mengindikasikan bahwa  kondisi arus stabil dengan kecepatan kendaraan yang mulai terkendali. Dengan demikian, kapasitas ruas Jalan Ir. M. Putuhena saat ini masih mampu menampung volume kendaraan, namun diperlukan pengelolaan lalu lintas yang lebik baik untuk mencegah penurunan tingkat pelayanan di masa mendatang.
