Abstract

The dam foundation is a basic structure that meets the requirements as a supporting sector for dam construction and ensures safety against one of the serious threats in the form of seepage and Piping. Therefore, analyzing the stability of the dam foundation against seepage and Piping is necessary. This study uses the Finite Element program to analyze stability, seepage, and Piping under Normal Water Level conditions. Dam stability analysis is carried out by adding earthquake load coefficient factors OBE (Operating Basis Earthquake) and MDE (Maximum Design Earthquake). The analysis is carried out in two stages, namely the first stage without additional repairs and the second stage with additional repairs in the form of Curtain Grouting and Cut-off wall. Under Normal Water Level conditions without earthquakes or with OBE and MDE 1.00H earthquakes, the stability of the foundation in Existing conditions, Alternative 1, and Alternative 2 meets the criteria, but does not meet the MDE 0.25H, 0.50H, and 0.75H earthquakes so that dynamic analysis is required using the Makdisi-Seed method. Seepage analysis shows that the discharge in the Existing condition is 49,716.74 m³/day exceeding the permit limit of 45,000 m³/day, while Alternative 1 (255.13 m³/day) and Alternative 2 (238.55 m³/day) meet the criteria. Meanwhile, Piping analysis in Normal Water Level conditions shows that the Existing does not meet the Safety Factor, while Alternative 1 and Alternative 2 meet the criteria and are safe for Piping.

Abstract

Handling anxiety can be done pharmacologically or non-pharmacologically. Several non-pharmacological therapies that can be used to reduce anxiety levels include relaxation therapy, sound therapy, and aromatherapy. Some examples of sound therapy are classical music therapy and murottal Al-Qur'an. The Aim of this research is to determine the effect of classical music therapy and Al-Qur'an murottal therapy on the patient's anxiety level before tooth extraction by observing changes in blood pressure before and after listening to classical music and Al-Qur'an murottal. This type of research is quasi-experimental with a pretest-posttest design. The research sample consisted of 30 patients with indications for tooth extraction divided into 2 groups: the group that was given classical music therapy Sonata in D major for two pianos, and the group that was given murottal therapy Al-Qur'an Al-Insyirah Surah and its translation and then assessed blood pressure before and after giving classical music therapy and murottal Al-Qur'an therapy. The distribution of patient anxiety which is known through the MDAS-Modification questionnaire shows that anxiety is in the moderate category. The Paired T-test results on blood pressure values of each pre and post intervention treatment group showed a p-value for classical music systole was 0.132, classical music diastole was 0.148, Qur'an murottal systole was 0.000, and Al-Qur'an murottal diastolic was 0.000. The results of the Independent T-test on blood pressure values between the two pre and post-intervention treatment groups were p-value systole of classical music and murottal Al-Qur'an was 0.000, and diastolic classical music and murottal Al-Qur'an was 0.000. The conclusion is listening to classical music and murottal Al-Qur'an can reduce patients' anxiety before tooth extraction. Murottal Al-Qur'an reduces patient anxiety before tooth extraction better than classical music

Abstract

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.
