Purpose of this study was to determine and analyze Financial Ratios to Assess the Performance of the Lumajang Regency Transportation Service. The method used in this research is quantitative with the technique of collecting data documentation on the financial statements of the Department of Transportation in the form of operational reports, budget realization reports and balance sheets which will later be calculated the effectiveness ratio and harmony ratio and adjusted to Government Accounting Standards (SAP). The results of this study are that the Lumajang Regency Transportation Service is still not effective in 2017 and 2019 because there is a deficit in that year. Meanwhile, 2018 has been effective because the criteria are above 100%, namely 101, 39%. So it is said to be effective because the income is greater than the PAD budget and has a surplus from non-operational activities. The compatibility ratio increases every year so that the calculation has a matching criteria every year because all spending is optimized on resources.

This study aimed to determine the nitrogen content of spinach leaves by using computer imaging technology. The application of Color Co-occurrence Matrix (CCM) texture analysis was used to recognize the pattern of nitrogen content in spinach leaves. The texture analysis consisted of 40 CCM textural features constructed from RGB and grey colors. From the 40 textural features, the best features-subset was selected by using features selection method. Features selection method can increase the accuracy of image analysis using ANN model to predict nitrogen content of spinach leaves. The combination of ANN with Ant Colony Optimization resulted in the most optimal modelling with mean square error validation value of 0.0000083 and the R2 testing-set data = 0.99 by using 10 CCM textural features as the input of ANN. The computer vision method using ANN model which has been developed can be used as non-invasive sensing device to predict nitrogen content of spinach and for guiding farmers in the accurate application of their nitrogen fertilization strategies using low cost computer imaging technology.

Dried cabya (Piper retrofractum Vahl.) is commonly used in making various types of herbs, spices, and cosmetic raw materials that require heating processes so that they require information on the value of thermal conductivity (k), thermal diffusivity (α), and specific heat (Cp). The thermal properties of dried cabya are affected by different phytochemical compositions at each maturity stage of the fruit. This study aims to determine and analyze the thermal properties and phytochemical content of dried cabya in three stages of green, orange and red maturity. Measurement of thermal diffusivity in this study uses the principle of onedimensional unsteady-state conduction heat flow using a vertical thermal diffusivity test. The value of thermal conductivity is determined indirectly by a calculation method based on the value of thermal diffusivity, specific heat, and density of the material. The thermal conductivity values of green, orange, and red paste cabya are 0.241 ± 0.016, 0.298 ± 0.005, and 0.344 ± 0.025 W/m°C. Reducing sugar levels in dried green, orange, and red cabya are 2.32 ± 0.16, 4.07 ± 0.13, and 6.44 ± 0.13 %, piperine levels are 2.42 ± 0.01, 1.97 ± 0.06, and 1.54 ± 0.05 %, and antioxidant levels are 87.15, 75.26, and 63.38 mg/mL. Based on the results of the study, red dried cabya have higher values of α, Cp, and k compared to orange and green because they contain higher levels of water and reducing sugars. However, red dried cabya have piperin and antioxidant levels which are getting lower

A B S T R A C TMicrofiltration is a low pressure driven membrane process of about 1 bar trans-membrane pressure which is used frequently for separating dissolved particles within 0.1 to 10 μm size. Microfiltration membranes are utilized in water and wastewater treatment processes either during pretreatment, treatment, or post-treatment steps. Moreover in bioprocessing, microfiltration is used in upstream process for substrate sterilization or in downstream process for microbial suspension separation. Fouling is one major concern of membrane filtration processes, including microfiltration. In this article, the fouling mechanism on microfiltration membrane is explained based on the blocking model refer to cake filtration due to the complexity of fouling phenomena. Fouling mechanism on dead-end and cross-flow modes microfiltration are explained, and basically distinguished into four different mechanisms, i.e. complete blocking, standard blocking, intermediate blocking and cake filtration. The proposed models are based on constant pressure operation on the uniform membrane pores, both for dead-end and cross-flow modes. Cross-flow mode, however, is restricted on the beginning of filtration until critical flux condition is reached.Keywords: bioprocess; blocking model; cake filtration; fouling; microfiltration; wastewater A B S T R A KMembran mikrofiltrasi merupakan salah satu teknologi membran yang menggunakan tekanan rendah sekitar 1 bar sebagai gaya pendorong dan digunakan untuk proses pemisahan partikel terlarut yang berukuran antara 0,1 hingga 10 μm. Membran mikrofiltrasi banyak digunakan baik dalam proses pra-pengolahan, pengolahan, maupun pasca-pengolahan air dan air limbah. Pada bioproses, mikrofitrasi juga digunakan pada proses hulu untuk sterilisasi substrat atau pada proses hilir untuk pemisahan suspensi mikrob. Masalah yang paling utama dalam proses filtrasi membran adalah fouling. Dalam artikel ini, mekanisme terjadinya fouling pada membran mikrofiltrasi dijelaskan dengan menggunakan model pemblokiran yang mengacu pada filtrasi deposit partikel (cake) untuk menguraikan kerumitan fenomena fouling dalam mikrofiltrasi. Pada tulisan ini dijelaskan lebih rinci mengenai mekanisme fouling baik pada mikrofiltrasi searah (dead-end) maupun aliran silang (cross-flow). Mekanisme fouling pada proses mikrofiltrasi bisa dimodelkan dengan empat model yaitu pemblokiran pori, penyempitan pori, pemblokiran pori bersamaan dengan endapan permukaan dan formasi endapan permukaan. Mekanisme tersebut berlaku pada kondisi operasional bertekanan tetap dan ukuran pori yang seragam, baik pada aliran searah ataupun silang. Hanya saja, model mekanisme pada aliran silang hanya berlaku pada kondisi awal filtrasi hingga tercapai kondisi fluks kritis.Kata kunci: air limbah; bioproses; filtrasi cake; fouling; mikrofiltrasi; model pemblokiran
