Abstract

Clays are soft soil which have a low bearing capacity. One of the methods to determine the soil bearing capacity is CBR (California Bearing Ratio). Research on Laboratory for determining CBR value of soil generally performed on condition of optimum moisture content or fully saturated soil. This research evaluates the CBR value of clays with various fly ash contents from OMC to fully saturated. The results showed that, when the soil is compacted at OMC conditions, the effect of saturation resulted will decrease the CBR value up to 67% of CBR unsoaked. When soil is compacted with moisture content above the OMC, increase of water content resulted will decrease the CBR value up to 24%. Furthermore, the addition of fly ash content is effective to improve the CBR value between 20% -25%.  Key Words: CBR, water content, clay, fly ash

Abstract

Helical pile can provide an alternative for wood pile over peat soil. The reaserch studied about the effect of amount of helical plates to lateral capacity of helical pile and compared to wood pile and helical without pile. The amount of helical plates used were L, 2L, 3L, LM, and LMS with spacing 50cm. Lateral ultimate capacity was interpreted by Tangent Intersection and. Theoritical lateral capacity of helical pile was calculated using Broms method. Data obtained from experiments in the form of load and displacement described in the normal scale and interpreted by using method tangen of intersection. It is known that increasing the addition of the same diameter of helical plate will increase the lateral bearing capacity of helical pile. But if the bottom of helical plate is smaller then the addition of helical plate no significant effect on the lateral bearing capacity although the helical plate on it larger.Loading experimental results were compared with the result of calculation lateral bearing capacity used Broms method. From the comparison note the lateral bearing capacity of the field is greater than analytical lateral bearing capacity.Keywords: Helical Pile, amount of Helical Plates, Peat soil, lateral Capacity, Wood Pile, pile without helical.

Abstract

The practice of gambling is growing day by day in various levels of society, from the lower classes to the upper classes. This was proven when the Pesisir Selatan Criminal Investigation Unit (Sat Reskrim) arrested 7 (seven) mothers who played playing card gambling in Kampung Samudera, Kenagarian Surantih, Sutera District, Pesisir Selatan on October 21, 2017. But before taking the route criminal law in general, this case has been resolved by customary law in Pesisir Selatan by receiving customary sanctions. This research is a descriptive analytical study. The approach used in this study is a normative juridical approach supported by an empirical juridical approach. From the results of the research it can be explained that: First, the application of customary sanctions in the settlement of gambling crimes in Pesisir Selatan Regency, is by considering local rules and discretion made by the Head of Criminal Investigation Unit of the Pesisir Selatan Police. Where deliberation leaders, traditional, religious and family leaders hold a meeting, the results of the deliberation are conveyed to the police so that the suspects will be given customary sanctions, in the form of requiring them to walk from the location of arrest to one of the mosques, and vowing not to repeat the act again. Second, the obstacles to the application of customary sanctions in solving gambling crimes in Pesisir Selatan Regency are internal obstacles to the police and external obstacles to the police. There are settlement steps that can be taken in overcoming the obstacles that occur in overcoming gambling with preventive and repressive measures.
