    Dalam perencanaan pondasi diperlukan hasil analisis yang berasal dari penyelidikan tanah berupa daya dukung pondasi. Hasil daya dukung tersebut kemudian harus divalidasi, salah satunya adalah dengan uji PDA. Tetapi pada prakteknya, terjadi penyimpangan nilai antara hasil perhitungan teoritis daya dukung pondasi dan hasil uji PDA. Untuk itu, diperlukan sebuah metode teoritis yang mendekati akurat untuk perhitungan daya dukung pondasi yang mampu memikul beban diatasnya dengan baik. Untuk mendapatkan nilai daya dukung tersebut, data N-SPT diinput pada beberapa metode seperti metode Meyerhof (1976), metode Briaud & Tucker (1985), metode Aoki & de Alencar (1975), dan metode Luciano Decourt (1995). Berdasarkan hasil analisis, didapatkan pada pondasi borepile metode Meyerhof (1976) memiliki nilai rerata error terkecil pada Qult yaitu 0,46. Sedangkan pada tiang pancang metode Briaud & Tucker (1985) memiliki nilai rerata error terkecil pada Qult yaitu 0,09. Selain itu, grafik hubungan antara rasio daya dukung dengan waktu menunjukkan bahwa rasio daya dukung akan semakin besar seiring dengan bertambahnya waktu. Perbedaan jenis tanah, dimensi, dan kedalaman penetrasi tiang dapat mempengaruhi kecenderungan bentuk grafik

    Aim: The objective of this study was to determine the heavy metals pollution profile of Citarik, Cimande, and Cikijing Rivers. Methodology and Result: The method of this research to measured heavy metals was cadmium, chromium, copper and zinc. Determination of sampling point refers to SNI 03-7016-2004. The river water sampling procedure refers to SNI 6989.57-2008 on Water and Wastewater - Section 57. The water sample extraction method refers to Standard Method for the Examination of Water and Wastewater. Sediment sample extraction method refers to EPA Method 200.2-1994. The water sample extraction method refers to Standard Method for the Examination of Water and Wastewater. Sediment sample extraction method refers to EPA Method 200.2-1994. Based on test result and comparison to quality standard of Indonesian Government Regulation No. 82of 2001 on Water Quality Management and Water Pollution Control. The metal concentrations in the sediments were much higher than the concentrations of metals contained in water. This is due to the accumulation of metals in sediments that occur continuously. Conclusion, significance and impact study: The concentrations of four metals in water and sediments after river points higher than before passing the industrial area, it indicates that anthropogenic arising from agricultural activities and textile industry near the rivers of Citarik, Cikijing, and Cimande rivers. The degree of contamination and seasonal variation of heavy metals were high in water and sediment

    Introduction: The purpose of this study was to reformulate Leā€™NaturaĀ® biscuit for textural, sensorial, nutritional and glycemic index properties improvement. The original biscuit had a brittle and coarse texture with a bitter after-taste. It also contained high carbohydrate which made the biscuit unsuitable for diabetic patients and less desirable to the health-conscious consumers. Methods and Results: Several ingredients from the original formulation were either eliminated, reduced or substituted in order to modify the texture and taste, to obtain a low glycemic index (GI) value and to increase acceptability. The ingredients involved in reformulation were wheat flour, milk powder, maltodextrin, atta flour, green bean flour, polydextrose, palm oil, and leavening agents. The final reformulated biscuit showed improvements in thickness, spread ratio, fracturability and firmness properties. The improved biscuit also scored higher acceptability for appearance, texture, sweetness, after-taste and overall acceptability attributes. The in vivo GI measured indicates that the improved biscuit was in the low GI range of 44.7Ā±4.7 compared to the original biscuit (63.5Ā±7.7, moderate GI). The nutrients composition of total energy, fat, protein, dietary fiber, iron, and calcium content were increased while total carbohydrate and sodium levels were decreased. Conclusions: With the improvements, Leā€™NaturaĀ® biscuit is expected to capture the functional food market segment more competitively. Keywords: functional food; biscuit; glycemic index; high fibe

    Family functioning is a pivotal factor influencing childā€™s problems including mental, behavioral, and developmental disorder. This study aimed to assemble and validate family functioning scale using confirmatory factor analysis. The research was done on 134 late adolescences, age ranges were between 18-22 y.o. Family functioning scale was developed from the process model of family functioning which has seven components i.e., task accomplishment, role performance, communication, affective expression, affective involvement, control, and value and norm. The result shows that all components have significant factor loadings, and the scale is reliable. However, the data has shown that the model is not fit enough indicated by underperformed CFI. TLI, and RMSEA. Suggestions for future development were discussed.Keberfungsian keluarga merupakan faktor penting dalam mengatasi permasalahan-permasalahan anak seperti gangguan mental, perilaku, dan perkembangan. Penelitian ini bertujuan untuk menyusun dan memvalidasi skala keberfungsian keluarga menggunakan analisis faktor konfirmatori. Penelitian dilakukan terhadap 134 remaja akhir dengan rentang usia 18-22 tahun. Instrumen skala keberfungsian keluarga dikembangkan berdasarkan teori proses keberfungsian keluarga yang memiliki tujuh komponen yaitu pencapaian tugas, kinerja peran, komunikasi, ekspresi afektif, keterlibatan afektif, kontrol, dan nilai serta norma.
