Abstract

Currently, the condition of fishing facilities for Acehnese fishermen is experiencing difficulties with raw materials due to the difficulty of obtaining good quality wood that is resistant to immersion in water. The Aceh boat measuring 7 meters long which is often referred to in the Acehnese language, namely Boat thep thep is one of the facilities used by Acehnese fishermen to carry out all activities. The application of composite materials or the method of making composites through Hand lay up and Spray up technology is very appropriate to solve this problem. The application of thermosetting polyester resin reinforced with E glass fiber has been proven to be able to increase the efficiency of using this method to become a superior product. This is very appropriate to answer the problems of Acehnese fishermen who have continued to experience losses in the operational cost sector. The main objective of the activity is to create an entrepreneurial partner unit that has the passion and expertise to increase competitiveness against fellow competitors who are directly related to the food security program. national. This is a manifestation of the use of campus academic research results for the community. The target of implementing this product-based science and technology program for the community is that in the short term, it will prioritize increasing the ability of partners and students to improve skills, improve skills in how to produce 2 GT Boats, with improving business management, and help create access to form new business worlds.

Abstract

Entering the economic era of free competition, various fishing technology supports have increased, but there are difficulties in terms of the availability of fish storage media in the long term. Products circulating today are not able to last long and are easily damaged. The problem that occurs is that the storage media does not have long durability against age, impact, maintenance and ease of repair. The composite material application applies the hand lay up method. The work process is carried out in stages starting from making patterns, molds to finished products. The material used consists of thermosetting resin, supported by reinforcing fiber consisting of E-glass fiber and organic ramie fiber. The combination of the two is called a hybrid material. The stages of this process are carried out efficiently and carefully until the final target is met for a quality Ice cool box product. Ice cool box composite as a direct application of campus research results so that it can be used for the needs of Acehnese fishermen.

Abstract

The Singkil Sub-district of Aceh Singkil District comprises alluvium deposits with a relatively low ultimate bearing capacity. The ultimate bearing capacity of the soil is closely related to the safety of a building. The important thing related to estimating the ultimate bearing capacity of the soil is in-situ soil investigation. This study aims to estimate the spatial distribution of soil ultimate bearing capacity using field test data in the Singkil Sub-district. Estimating ultimate bearing capacity is useful to provide an initial picture for various planning and infrastructure development activities in the study area. Twenty CPT in-situ tests have been obtained from various field works in Aceh Singkil Regency. Field data analysis, based on empirical methods, was carried out to obtain the value of the ultimate bearing capacity of the soil at the test location. Then, the estimated distribution of the maximum bearing capacity obtained was carried out. The zoning map of the distribution of soil ultimate bearing capacity in the study was developed from this research. This map can be used as a form or effort of disaster mitigation by various stakeholders involved in planning and building various infrastructure facilities in the Singkil Sub-district

Abstract

Abstract: Aceh – Indonesia, is a province that is prone to the earthquake strike because of the position of it which is close to earth fault. There are subduction tectonic fault, Indo-Australia, Euo-Asia tectonic faults, and Sumatra fault.  The aim of this research was to analyse the probability of sand soil failure (liquefaction potency) as the earthquake strike. The earthquake waves when it reaches the saturated of sand soil layer as a cyclic loads, leads the sand soil layers to fail (soil liquefaction). The soil formation will be change due to the cyclic loads and increase the pore water pressure, as a result the soil shear strength will decrease or even loss strength and becomes like fluida. The location of the research is in Krueng Raya beach in Aceh Besar – Aceh province. The data were obtained from N-SPT test and showed that the soil layers are dominant with sand soil layers. Seed et al (1976) and Castro (1975) were used to analyse the liquefaction potency. The research shows that liquefaction occurs in the depth of 3 m – 15 m for Seed et al (1976) method whereas no indication of liquefaction shows from Castro (1975) methods in any depths.Keywords : Liquefaction, subduction, potential, cyclic load, N-SPT.Abstrak: Aceh – Indonesia, merupakan provinsi yang rawan terhadap gempa dikarenakan antara lain Aceh berada di sekitar pantai barat Sumatera yang merupakan daerah pertemuan dari plat tektonik dasar laut (subduksi), plat tektonik Indo-Australia, Euro-Asia, dan patahan Sumatra Fault yang dapat mempengaruhi gempa. Penelitian ini bertujuan untuk menganalisis potensi keruntuhan struktur tanah pasir (potensi likuifaksi) apabila terjadi gempa bumi. Pada suatu lapisan tanah pasir yang jenuh air, getaran-getaran gempa bumi menyebabkan potensi terjadi suatu gejala likuifaksi yang merupakan gejala keruntuhan struktural tanah akibat menerima beban siklis (berulang). Beban siklis ini menimbulkan perubahan-perubahan di dalam deposit, berupa peningkatan tekanan air pori sehingga kuat geser tanah menjadi berkurang atau bahkan hilang (loss strength) sehingga berperilaku seperti fluida. Studi ini dilakukan pada lokasi pantai Krueng Raya Aceh Besar Provinsi Aceh. Berdasarkan data sekunder N-SPT, diperoleh lubang bor yang struktur tanah per lapisan dominan pasir. Potensi likuifaksi dianalisis dengan menggunakan metode-metode analisis Seed et al., (1976), dan Castro (1975). Hasil studi ini menunjukkan bahwa analisis likuifaksi dengan menggunakan metode Seed et al. (1976) terjadi pada kedalaman 3 m - 15 m dengan magnitude lebih besar dari 7,0 SR. Sedangkan analisis dengan menggunakan metode Castro (1975) pada kedalaman yang sama dengan tinjauan Seed et al (1976) likuifaksi tidak terjadi.Kata kunci : Likuifaksi, subduksi, potensi, beban siklis, N-SPT.

Abstract

Bearing capacity of the soil and the foundation has a close link with the level of safety to the occupants of a building. A foundation design said to be true if the load transmitted by the foundation to the ground does not exceed the power of the land concerned.If the soil strength is exceeded, then a decrease (settlement) excessive or collapse of land will occur, causing damage to the construction which is above the foundation. This research aimsto obtain the value of the soil bearing capacity of shallow foundations in several areas of Aceh Besar, and used as a mapping using ArcGIS 9.2 software. Secondary data used is Cone Penetration Test (CPT) ere obtained from the Laboratory of Soil Mechanics Faculty of Engineering, University of Syiah Kuala. Number of points CPT or sondir is 34 points.  Furthermore, to determine the location of these points in the field using GPS (Global Positioning System). The result shows that most of the area in the study area has a bearing capacity of the land is permitted 50 ton / m2. The area has bearing capacity permits between 50 ton/m2 to 100 ton/m2 occupied area Siem, Cot Gue, Bilui, Adjunct, Baet, Mon Ikeun,Lamkruet, and Lhoknga. Furthermore, the results of the bearing capacity of land used as a mapping so that it becomes a reference in planning the foundation of a building or otherinfrastructure in the region of Aceh Besar.
