This research was conducted to analyze the influence and correlation of interest rates as one form of the implementation of usury practices on inflation and poverty in Indonesia. This study uses secondary data from the publication of the Central Statistics Agency (BPS) and Bank Indonesia for the period 2005-2018. This study uses Simple Linear Regression Analysis Techniques and Pearson Correlation Techniques. The results showed that interest rates as one form of the implementation of usury practices had an effect and had a positive and significant correlation to inflation in Indonesia. The practice of ribawi actually will bring a negative impact on the economy of the people in Indonesia in the form of an increase in the level of inflation in society. Measures of monetary policy intervention in maintaining price stability and inflation in society have not shown a positive impact. Also, the results of the study showed that interest rate policy also had a positive influence and correlation on the increase in the poverty depth index. That is, when interest rates are set to rise, the poverty depth index in the community also tends to go up or get worse. The findings of this study reinforce the legitimacy of the word of Allah Subhanahu Wa Ta'ala in the Qur'an and the Hadith related to the prohibition of usury practices that can lead to injustice, wrongdoing, and economic destruction of the people.

The article considers the anticorrosive properties of inorganic di-and polyphosphate compositions in relation to St-3 steel, depending on the pH of the medium, the nature and concentration of phosphate, and the nature of the modifier ion. The research was conducted using GOST-based methods: gravimetry, potentiometry, photocolorimetry, infrared spectroscopy and scanning electron microscopy. On the basis of experimental data, quantitative indicators of corrosion process were determined: the rate of corrosion process, the degree of protection, the depth index, the coefficient of inhibition and the assessment of the stability of the formed film on the ball scale of corrosion resistance against steel. The analysis of experimental data allows to establish the influence of the above factors on the corrosion processes in the systems under study. The experimental data are supplemented by thermodynamic calculations of the corrosion process parameters, the results of which correlate well with the kinetic data of the process under study. In the course of the research work, the analysis of corrosion deposits was also carried out. The regularities established during the work contribute to the creation of effective di-and polyphosphate inhibitors with the highest degrees of protection.

Highly fractured rocks at Grasberg Mining in PT Freeport Indonesia (PTFI) lead to fractured groundwater flow media. Hydraulic conductivity of fractured rock has more complexity than that of porous rocks media. In this study, hydraulic conductivity (K) has been estimated according to HC-System based on Rock Quality Designation (RQD), Lithology Permeability Index (LPI), Depth Index (DI) and Gouge Content Designation (GCD). Numerical model of HC-System at Grasberg Mining in general can be expressed by the equation K = 2 x 10-6 x HC0.5571. The RQD data can be grouped into three ranges, i.e. first group that dominates over 80 % of the RQD data with K ranging between 1.9x10-8 – 2.3x10-7 m/s, second group that is within 40 – 80% of the RQD data with K falling between 2x10-8 – 7.2x10-7 m/s, and third group that takes part less than 40 % of RQD data with K ranging between 2.1x10-8 – 1.9x10-6 m/s. Based on the lithology, the hydraulic conductivity of rocks can be assinged as follows: igneous rock with K ranging 6.8x10-8 – 1.9x10-7 m/s, and sedimentary rock with K ranging 2.2x10-8 – 1.9x10-6 m/s. HC-System demonstrates good interpretation of hydraulic conductivity by means of clustering method, which uses geological and geotechnical data for hydrogeological characterization

Konduktivitas hidraulik merupakan parameter yang sangat penting dalam pemodelan aliran airtanah. Parameter tersebut dapat diambil melalui pengujian packer test dan slug test . Mahalnya operasional pelaksanaan pengujian tersebut, memberikan dampak minimnya data kondutivitas hidraulik di lapangan. Konduktivitas hidraulik pada batuan yang terkekarkan memiliki kompleksitas (derajad heterogenitas dan anisotropi) yang lebih tinggi dibandingkan dengan konduktivitas hidraulik pada batuan sedimen. Untuk mengatasi minimnya data konduktivitas hidraulik, dalam studi literature ini akan dilakukan cara prediksi nilai konduktivitas hidraulik dengan menggunakan pendekatan metode HC-System. HC-System merupakan metode empirik yang melibatkan data-data geoteknik menduga nilai konduktivitas hidraulik di daerah yang tidak ada data pengukuran (terbatas pada titik pengukuran geoteknik). Data geoteknik tersebut terdiri dari Rock Quality Designation (RQD), Lithology Permeability Index (LPI), Depth Index (DI), and Gouge Content Index

The objective of this study is to elaborate Serra da Estrela cheese with sheep's milk concentrate by ultrafiltration and characterize it in relation to protein, yield, proteolysis, amino acid profile, and acceptability. The cheese elaborated with concentrate milk (F2) presented an increase of 17% yield, and protein content was 2 times higher than cheese without concentrate milk (F1). On the 30thday of storage F2 presented an increase of the amino acids and also of proteolysis extension and depth index in relation to the 1st day. Also presented better sensorial characteristic in relation to F1. Were observed positive correlations (>0.85) between acceptability in relation to protein, depth index, extensionand extension index, valine, methionine, serine, phenylalanine aspartic acid, valine andproline. Cheese elaborated with concentrate milk and coagulated with thistle flower is one alternative to increase cheese yield with differential sensorial characteristics.
