PERANCANGAN PEMBUATAN PERMEN KAPAS OTOMATIS BERBASIS ARDUINO UNO

Cotton candy is one of Indonesia's traditional foods which was quite popular in its time. Cotton candy is made from sugar that is given food coloring, cotton candy is made using a special tool that rotates and produces refined sugar fibers. Most cotton candy consists of air cotton candy feels sweet and sticky. Even though it looks like wool yarn ... The design of this cotton candy maker uses an arduino uno microcontroller, equipped with a temperature sensor, 3 push buttons and a heating stove as a heating container for the sugar container design of this tool. All Arduino Uno microcontroller working systems have been programmed using the C program language on the Arduino Uno microcontroller. Using a dose of 1/2 spoonful sugar, the average initial temperature (54.5 ° C) and the average final temperature (64.8 ° C) were obtained. Measuring one (1) spoonful of sugar, the initial heating temperature with an average (68.8oC) average final temperature (74.2oC). The dose of sugar 1 1/2 spoon, the initial temperature of the heater with an average (70.4 ° C) the average temperature of the final heater (77.4). This tool takes time to heat the heating stove in approximately 2 minutes to reach ambient temperature (54oC). Testing to find out the exact time of each dose of sugar. as in the dose of half a sugar (1/2) a spoon an average of about 120 seconds is obtained, a dose of sugar (one) spoon is obtained an average time of about 150 seconds and in a sugar one and a half (1½) spoon an average time is obtained about 180 seconds. ABSTRAK:Permen kapas adalah salah satu makanan tradisional khas Indonesia yang cukup populer pada masanya. Permen kapas dibuat dari gula yang diberi pewarna makanan, permen kapas dibuat menggunakan sebuah alat khusus yang berputar dan menghasilkan serat – serat gula yang halus. Sebagian besar permen kapas terdiri dari udara permen kapas terasa manis dan lengket. Meskipun terlihat seperti benang wol..Perancangan pembuat permen kapas ini menggunakan mikrokontroler arduino uno, dilengkapi sensor suhu, 3 buah push button dan kompor pemanas sebagai pemanas wadah penampung gula perancangan alat ini. Semua sistem kerja mikrokontroller arduino uno sudah diprogram menggunakan bahasa program C pada mikrokontroler Arduino Uno.Menggunakan takaran gula 1/2 sendok, didapatkan suhu awal rata-rata (54,5oC) dan suhu akhir rata-rata (64,8oC). Takaran gula satu (1) sendok, suhu awal pemanas dengan rata-rata (68,8oC) suhu akhir rata-rata (74,2oC). Takaran gula 1 1/2 sendok, suhu awal pemanas dengan rata-rata (70,4oC) suhu akhir pemanas rata-rata (77,4). Alat ini membutuhkan waktu untuk memanaskan kompor pemanas dalam waktu kurang lebih 2 menit untuk mencapai suhu sekitar (54oC). Pengujian untuk mengetahui waktu yang tepat dari setiap takaran gula. seperti pada takaran gula setengah (1/2) sendok diperoleh rata-rata waktu sekitar120 detik, takaran gula satu (1) sendok diperoleh rata-rata waktu sekitar150 detik dan pada takarang gula satu setengah (1 ½) sendok diperoleh rata-rata waktusekitar 180 detik.

General Mathematical Model for Energetic and Informatic Evaluated over Natively Producing Surrounded Systems

Some joint (synthetic) closed in itself idea about the world and its being is expounded in the paper, which gives the opportunity to invent the parallel definitions of the energy and the information not exceeding the bounds of the united world. This allows us to introduce some sufficiently general notion of the evaluated produciпg (transmission-streamed conservatively-dynamic contained) surrounded system, described by the proper system of evolutional equations. In the capacity of important partial cases of such systems the proper notions of the energetic evaluated producing surrounded system and the informatic3 evaluated producing surrounded system are introduced. The explicitly analyzed earlier examples of the model of heating stove (as the energetic evaluated producing surrounded system) and the model of personal computer (as the informatic evaluated producing surrounded system) expose the applicability of proposed idea to a generalized and formalized description of some wide class of over native systems really existing.

Comparative evaluation of the performance of an improved solar-biomass hybrid dryer

A solar biomass hybrid dryer intially designed with a front pass flat plate solar air heater and a biomass heating stove was redesigned, reconstructed in order to minimize the excessive convective heat losses and its performance re-evaluated. Due to poor design and contruction of the biomass heating and solar collector sections, the efficiency of the initial design was low. It is believed that the drying efficiency of the dryer could be enhanced if a back pass solar collector and a biomass heating stove incorporated with a gas to gas heat exchanger to ensure that the hot air reaching the samples is clean, smokeless and ash free, substitute for the original solar collector and biomass unit respectively in the improved version. The system’s drying performance was tested on both no load and full capacity load under different meteorological conditions within Nsukka (Lat. 7oN) for two weeks. The testing results showed that the incorporation of a new back pass solar collector and the heat exchanger enhanced the trays temperatures on no load test. Similarly, the efficiency of the dryer based on solar, biomass and solar-biomass heating in drying of fresh okra, fresh groundnut and fresh cassava chips increased from 5.19 – 16.04%, 0.23 – 3.34% and 1.636 – 8.96% respectively over the initial construction. This shows that the dryer can help improve the post-harvest processing and storage quality of farm produce by drying if further optimized.
