Pengeringan Biji Kemiri Pada Alat Pengering Tipe Batch Model Tungku Berbasis Bahan Bakar Cangkang Kemiri

Generally, this research aimed to study drying characteristic of pecan seed on a Batch type (stove) dryer using pecan shell as fuel. Specifically, this research aimed to determine moisture content reduction, temperature change, drying rate, mass transfer rate, air dryer flow rate, energy requirement, drying efficiency, and drying capacity. This research used experimental method in order to determine drying characteristic of pecan on thin layer method using oven, which was conducted in laboratorium by temperature varied of 40oC, 50oC, 60oC, 70oC, dan 80oC. Thick layer method was conducted by trial mathematical model, i.e. collected data from drying stage on batch stove dryer then analyzed using software based on mathematical model, actual data were also collected from on field experiments. Measurement of pecan geometric characteristic also had been conducted. Result showed that pecan had sphericity number of 0.79. Characteristic curve of thin layer drying obtained from analytical result showed the drying rate was decreasing and correlation between ln MR (%db) with t (hours) on drying temperature of 40 oC to 80 oC showed decreasing moisture content and drying rate towards drying time. General equation for moisture content ratio, MR = exp (-0,0141.T – 0,2583)*t. Graphic of correlation between fuel (kg) and moisture content equilibrium (%) showed decreasing moisture content equilibrium at every fuel addition. Keywords: pecan, stove, drying, batch type &nbsp

Analisis Kebijakan Penanggulangan Kemiskinan Melalui Pendidikan Boarding School Smk Negeri 3 Di Kabupaten Purbalingga

Poverty is a classic problem of mankind in every part of the world andbecomes a complex issue because it is not just about low income. The low level ofeducation, skills, and the lack of introduction to technology are the human resourceconstraints that are closely related to the causes of poverty. Purbalingga regency isone of the areas with a high percentage of poor people who are always ranked in thepoorest areas in Central Java Province. The purpose of this research is to analyze thepolicy of poverty reduction by Purbalingga Government through establishment ofBoarding School of SMK Negeri 3 Purbalingga.This study uses mixed methods between qualitative and quantitative with aqualitative approach remains the main approach. Data collection techniques werecarried out, among others, by collecting documents and in-depth interviews withactors involved in the policy, and using a research questionnaire to the researchsubjects of alumni / boarding school graduate SMK Negeri 3 Purbalingga. Analysisof research data is done by combining primary data obtained and findings in bothqualitative and quantitative data.Based on the research that has been done, it is known that the policy has beenimplemented optimally, consistently, and there is a continuous suitability of visionamong policy actors in 3 different Heads of District (Bupati), and achievements thatcan penetrate TOP 35 in Public Service Innovation Competition (SiNovik) 2016.Quantitative data shows that there is an increase of living standards of alumni SMKNegeri 3 Purbalingga coming from poor families, as the object of poverty problem inPurbalingga Regency. This shows that policies that have the principle of breaking thepoverty chain have succeeded in reducing the number of poor people, thesustainability of the program is likely to reduce poverty significantly

Effectiveness of ATM security mechanisms: a review analysis

In the modern hasty word, Banks and ATM (Automated Teller Machine)s are inevitability possessions of all humans. With the use of ATMs people can do several financial transactions and related activities day to day life. The common authentication mechanism uses in ATM is card with PIN (Personal Identification Number) for the secure transactions since long time ago. But nowadays cause of the higher advancement in technology tends alert and fear among banks and ATM users thus it is important to overcome the problem to safe ATM activities. In this study, analyzes the recent and popular authentication mechanisms related to ATM security and recommends better solution from the past studies to increase ATM security in the process of authentication and to protect from illegal physical activities at the ATM. This study compares different combination of authentication mechanism including the classical PIN method and recommends the best solution by weighting four important attributes namely security Performance, Accuracy, Cost and Flexibility in terms of security. Based on the total score weighted from the comparison this study recommends a secure solution as a combination of two methods from the past studies. A two-step verification method with “PIN and Fingerprint or S-code (Secure-code) with OTP (One Time Password)” was identified as the best solution for authentication since its higher security and flexibility to the users, meanwhile another mechanism with “GPS and sensors” was recommended for the protection against the illegal physical activity and for providing post- tracing capability

Comparative analysis of functional test automation tools

The software development life cycle has several stages. Among them, software testing is a continuous process. It begins after the requirement-gathering phase. Today software testing has become a mandatory process. It comes with a variety of challenges also. Although manual testing is an easy task, sometimes it will not be effective due to its incompatibility, lack of coverage, and repetition of test scripts. This study mainly focuses test automation process and its working mechanism, software testing strategies, and different types of software testing tools. For clarification, test automation tools are divided into functional, test management, and load testing tools. The objective is to provide a comparative analysis of test automation tools with similar characteristics such as platform support, the programming language used, and compatibility with web browsers. This research paper also helps the test teams to select the appropriate test tool according to the customer’s needs

Pengeringan Lapis Tipis Kopra Putih Menggunakan Oven Pengering

West Nusa Tenggara has enormous potential as coconut producer in Indonesia. With total area 64.297,10 ha, it can produced coconuts in amount of 49670.93 tons (NTB in Figures, 2010). Most of the coconut was sent to Java Island, whereas some local communities process the coconuts into copra and traditional coconut oil. However, NTB as producer of copra has not been able to produce good quality copra because the traditional process is conducted using simple processing equipment, requires large human power, and long processing time. Due to these limitiation, it is necessary to implement appropriate technology by using shelf-type dryer (tray dryer) tool that utilizes solar energy as a source of thermal energy. Using solar collectors panel, the dryer produce heat higher than using direct drying and the temperature can be controlled. Purpose of this study was to determine characteristics of copra drying processes (temperature, relative humidity, effective drying rate, and relation between effective drying rate and water content) using oven as ideal drying tool, for further application on solar-energy tray-dryer type. Drying was conducted until water content achieved 9%, the observed and calculations data were plotted into graphic then studied descriptively. Calculated variables are reduction in weight material, moisture content, drying air temperature, ambient air temperature, outflow air temperature, material temperature, air humidity, drying efficiency, air flow rate, and intensity of solar radiation. Constant value indicates that the higher the drying air temperature, the more rapid time were needed to decrease moisture content of the material, therefore the obtained general equation for water content ratio becomes MR = exp (-0,0141.T - 0.2583) * t
