Soft clay soils generally have unfavorable characteristics or properties, when used as a basis for a construction. The characteristics of soft clay soil are having high soil compressibility, low carrying capacity, low permeability value, being cohesive and having a high level of soil activity. One form of effort to improve the characteristics of the soil's bad properties is to carry out stabilization. Stabilization is an activity of mixing soil with certain materials, and is expected to react with the soil, so that the soil characteristics become better. The methodology applied in this study is chemical stabilization, with mineral materials in the form of marble ash waste with 4 different types of variants. Based on the test results, there was a decrease in the value of the water content and soil plasticity index (PI) of 44.94% in variant 3 (20% marble ash waste) compared to the original soil. It is estimated that there is a reaction from the marble ash on soft clay soil, namely in the form of absorption of excess water contained in the soil and voids contained in the soil filled with marble waste, so that the adhesion between particles becomes better.

This study aims to measure the efficiency of Takaful companies in Southeast Asia and the Middle East region. The efficiency level of Takaful companies in Southeast Asia and the Middle East region was examined from 2016 to 2020. The sample consisted of 23 companies in Indonesia, 14 in Malaysia, three in UEA, and 31 in Saudi Arabia. The efficiency value of Islamic insurance companies was calculated using the Stochastic Frontier Analysis (SFA) method, afterward, the Mann-Whitney test was performed. The results showed that the efficiency median value of the companies in Southeast Asia was lower compared to the Middle East with respective values of 0.26 and 0.32. It was concluded from the results of the Mann-Whitney test that the differences in the median efficiency value of Islamic insurance companies in Southeast Asia and the Middle East were not significant. The novelty of this research is to provide new and significant information on the performance of Takaful Companies during 2016-2020. The results of this study have significant implications for policymakers in each of the countries examined to understand the efficiency condition of Takaful companies in the region. Furthermore, policymakers in Southeast Asia need to promote low-efficiency Takaful operators to expand their business. The lowest efficiency score for Takaful companies is in Indonesia, especially for small Takaful companies. The implication is that the Indonesian government or related agencies need to increase the popularity of Takaful companies among the public so that income and efficiency increase.

This paper aims to analyze the efficiency value and compare the efficiency ratio between sharia insurance and conventional insurance companies, both life insurance and general insurance in Indonesia, for 2018-2020. The research applies the Stochastic Frontier Analysis (SFA) method, which uses total capital and expenses as input variables, and total income as output variables. The efficiency values of Islamic and conventional insurance companies' results were compared using an independent sample t-test statistical test. The population of this research is all Islamic and conventional insurance companies listed on the website of the Financial Services Authority (OJK). The sample used is 19 sharia insurance companies (15 life insurance companies and four general insurance companies). The sample of conventional insurance is 23 companies (22 life insurance companies and one general insurance company). The results showed that the efficiency value of Islamic insurance companies (0.6549) was 0.0697 lower than conventional insurance (0.7246). It can be concluded that the efficiency of conventional insurance is better than Islamic insurance. Islamic insurance management capabilities are lower than conventional insurance companies’ management capabilities.

Salah satu upaya untuk mewujudkan kinerja simpang dan ruas jalan yang baik adalah terpenuhinya kapasitas pada semua simpang dan ruas jalan yang ditandai dengan karakteristik arus yang lancar dan stabil serta tercapainya kecepatan rencana. Salah satu simpang yang dijadikan lokasi penelitian terletak pada simpang tiga tidak bersinyal Jl.Daeng Moh Ardiwinata – Jl.Jati Serut, dimana simpang ini berada pada Kota Cimahi dan merupakan salah satu simpang penghubung menuju ke kota Bandung. Sebelum pandemi, Pemerintah Kota Cimahi telah memberlakukan rekayasa lalu lintas pada simpang ini, namun belum begitu terlihat manfaatnya karena pandemi melanda dan pergerakan kendaraan menjadi terbatas. Pedoman yang digunakan dalam menganalisis simpang tidak bersinyal di daerah perkotaan ini adalah PKJI 2014 untuk mengetahui apakah simpang masih berada dalam kapasitasnya dan dapat melayani dengan baik lalu lintas yang ada di atasnya serta Permenhub KM no.14 tahun 2006. Berdasarkan hasil analisis yang telah dilakukan didapatkan tingkat pelayanan simpang dalam memberikan layanan terhadap lalu lintas dalam kondisi normal berada pada nilai 0,86 sedangkan setelah dilakukan rekayasa lalu lintas berada pada nilai 0,54, dengan demikian rekayasa lalu lintas yang akan diberlakukan kembali dapat meningkatkan salah satu variabel kinerja simpang sebesar 37% dan menjadikan arus pada simpang sangat stabil.

Background: Parenting styles for children are given from an early age, which is a way of educating children to form personalities that will be carried into adulthood. Parenting styles will affect children's development both in gross motor and fine motor skills, personal and social interactions, and language.Objective: The aim of the study was to determine the strength of the relationship between parenting style and the development of pre-school children at Posyandu Kaliboto Karanganyar.Method: The research method is quantitative and cross-sectional. At Kaliboto Posyandu, the under-five population was studied by taking samples using the Slovin formula and obtaining 85 respondents who met the criteria of being parents and having children under the age of five (aged 3-5 years). The instruments used were a questionnaire for parents and the Denver Development Screening Test (DDST) sheet to measure children. Data analysis using Spearman rankResult: The results showed that 57.6% of parents practiced democratic parenting, and 62.4% of children under the age of five showed normal child development. The results of bivariate analysis with Spearman Rank obtained a p value of 0.000 and a positive correlation coefficient value of 0.547.Conclusion: There is a relationship between parenting style and the development of medium-strength preschool-aged children at Posyandu Kaliboto. The parenting style applied by the majority is democratic, and the majority of preschool-aged children are normal. It is expected to be the basis for parents to apply parenting in a democratic manner in order to optimize the development of preschool children.
