Abstract

Economic growth that increases the traffic load on national roads requires these roads to have decent, safe and comfortable services. Landslide was occurred on the Sekayu-Mangun Jaya STA 127+350 road section which disrupted traffic activity. This occurrence caused the major road to shift sideways and deteriorate, rendering the route's service capacity insufficient. The road section has been repaired and is planned to use soil retaining wall reinforcement as a countermeasure. This study aims to determine the slope stability of the Sekayu-Mangun Jaya road before and after reinforcement is carried out. Slope stability analysis was performed by empirical methods using infinite slope theory and the finite element method using the Plaxis program. The calculation results show that the safety factor of the slope before the retaining wall is installed at BH-01 is 0.9. This value falls under the category of unstable slope. The safety factor at the BH-02 location was obtained at 1.3 in the moderate stability category. Slope stability after strengthening with the installation of embankments and retaining walls shows an increase in the safety factor at BH-01 to 2.59. After the slope reinforcement was carried out, the slope deformation decreased significantly to 1.5 m. The results implicated that with slope reinforcement, slope stability increases and the possibility of landslides decreases.

Abstract

The foamed mortar (morbus) lightweight material consists of a mixture of sand, cement, water, and liquid foam (foam agent), which can improve the mechanical properties of clay soil and increase its bearing capacity. This research uses various variations of superplasticizer mixtures, namely by adding additional ingredients in the form of sikament-LN which will increase compressive strength by up to 40% at 28 days. This research needs to be carried out to determine the effect of sikament-LN on increasing the compressive strength of foamed mortar. The percentages of the sikament-LN mixture were 0.5%, 0.75%, 1%, and 1.25% with ages of 7, 14, and 28 days, each of which made 3 test objects in 4 variations of the mixture. The research results showed that the addition of sikament-LN to the 1.25% mixture did not meet the requirements because it produced a flowability of 23.5 cm and the mixture experienced a shrinkage of > 20% when placed in a cylindrical mold. All foamed mortar specimens experienced an average dry density increase of 1.994% at a curing age of 7 to 14 days and an average dry density increase of 4.044% at a curing age of 7 to 28 days. In a mixture of 0.5%, 0.75%, and 1%, at 28 days the maximum compressive strength value obtained was 841,667 kPa (more than the required 800 kPa). For the sikament-LN mixture, a maximum of 1% of the cement weight is recommended so that the hardening process occurs in the foamed mortar test object.

Abstract

Nowadays, the opportunity to get a job is depend on education degree. Therefore, looking for job opportunities such as entrepreneurship is an alternative for people who have limited degree of education. The 50 kota sub-district is the area with the largest coconut plantations in the 50 kota district. Apart from producing coconuts for sale, coconut trees can also be used as material for making furniture. This is a business opportunity for residents by utilizing coconut tree waste and wood waste. The solution to this condition is to provide knowledge training to young people who are not yet working and wood business people in the area to be able to create innovative furniture products. Of course it has a connection in reducing the number of people who are not working. The use of wood waste that can be obtained from processing coconut trees that are quite old and cannot produce good coconuts, as well as other wood waste can be utilized by creating simple furniture/decoration products that have selling value. This can certainly be a business opportunity for the community/youth of Karang Taruna who have not/don't work to become competent entrepreneurs independently. PKM activities begin with conducting field observations, providing material regarding sources of wood waste, types of wood, marketing steps in selling furniture products and continue with providing training on how to process wood waste into simple furniture/decoration products. The implementation of the work is carried out directly by the community/youth of Karang Taruna, then an evaluation is carried out by looking at the results of the product work by looking at its attractiveness and aesthetics so that it can become an item of marketable value on the market.

Abstract

This research was carried out using the P laxis 8.0 finite element method and manual calculations as well as by evaluating the safety factor value. Slope stability analysis using the P laxis program aims to determine the safe value of the slope before and after reinforcement using a cantilever - type retaining wall. Based on the analysis of the P laxis program before the installation of the cantilever retaining wall, in general the condition of the retaining wall on Jalan Ahmad Yani Gg. Batu Mas, Singkawang City experienced a landslide due to the condition of the soil which was classified as having low soil mechanical properties. Slopes with designed cantilever wall reinforcement are considered safer because they have the smallest displacement and settlement values, and meet all slope stability requirements, ie, shear stability is 1.251 > 1.5 (Safe), stability against overturning is 2.415 > 2 (Safe) , and bearing capacity is 0.555 < 0.583. The cantilever retaining wall structure uses D16-100 principal reinforcement and D10-100 shrinkage reinforcement, the base plate uses D16-150 principal reinforcement and D10-100 shrinkage reinforcement.
