Abstract

Abstrak. Metode pengeringan menggunakan surya sebagai sumber energi panas adalah metode pengeringan yang banyak digunakan. Besarnya panas yang dihasilkan tergantung dari jumlah radiasi matahari yang dapat ditangkap oleh kolektor surya. Tangkapan radiasi matahari dapat dioptimalkan dengan merekayasa kolektor surya yang dapat bergerak mengikuti posisi matahari. Kualitas produk pangan yang dikeringkan sangat dipengaruhi oleh aliran udara panas pada proses pengeringan. Berdasarkan permasalahan tersebut, perlu dilakukan kajian tentang aliran udara panas pada kolektor surya yang bergerak mengikuti posisi matahari. Penelitian menggunakan 2 buah kolektor surya yang direkayasa dengan ukuran, bentuk dan bahan yang sama dimana salah satu kolektor berada dalam kondisi tetap dan kolektor lainnya dapat bergerak mengikuti posisi matahari. Kecepatan aliran udara panas yang keluar dari saluran keluar (outlet) kolektor surya divariasikan menjadi 3 perlakuan yaitu 2 m/s, 4 m/s dan 6 m/s. Pengambilan data dimulai dari pukul 08.00 sampai pukul 16.00 dengan selang waktu pengambilan data adalah setiap 30 menit. Hasil analisis menunjukkan bahwa kecepatan udara panas pada outlet kolektor surya sangat berbeda nyata pengaruhnya terhadap nilai temperatur udara panas di dalam dan outlet kolektor surya. Kolektor surya yang bergerak mengikuti posisi matahari dapat meningkatkan performansi temperatur di dalam dan outlet kolektor surya pada berbagai kondisi kecepatan udara outlet berbanding kolektor surya tetap. Kenaikan performansi tertinggi di dalam dan outlet kolektor surya diperoleh pada kecepatan udara outlet 2 m/s masing-masing sebesar 16,29% dan 3,98%.  Analysis of Fluid Flow Speed on Solar Collector Performance which Moves to follow the Position of the Sun Abstract. The drying method using solar as a source of heat energy is a widely used drying method. The amount of heat produced depends on the amount of solar radiation that can be collected by solar collector. The capture of solar radiation can be optimized by construction the solar collector that can move in the sun's position. The quality of dried food products is strongly influenced by the flow of hot air in the drying process. Based on these problems, it is necessary to study the flow of hot air in solar collectors that move in the sun's position. The study used 2 units of solar collector that construction with the same size, shape and material where one of the collectors is in a fixed condition and the other collector can move in the sun's position. The velocity of hot air flowing out of the outlet of the solar collector was varied into 3 treatments, namely 2 m/s, 4 m/s and 6 m/s. Data collection starts at 8:00 a.m. until 16:00 p.m. with an interval of data collection is every 30 minutes. The results of the analysis show that the hot air velocity at the solar collector outlet has a very different effect on the temperature value of hot air inside and the solar collector outlet. Solar collector that move in the sun's position can increase the temperature performance in and solar collector outlets in various conditions of outlet air velocity. The highest increase in performance in and solar collector outlets was obtained at outlet air velocity of 2 m / s at 16.29% and 3.98% respectively.

Abstract

Various types of power threshers have been developed to suit conditions in the field. The development of the power thresher was also carried out by UPJA Sungai Kelambu Village, Sambas Regency by making a mini power thresher that was designed to suit the conditions of the land and the needs of local farmers. The purpose of this research was to obtain a relationship between threshing rotational speed and performance on the mini power thresher. The threshing cylinder rotational speed was varied at 669 and 778 rpm. The measured performance of the mini power thresher was feeding capacity, threshing capacity, cleanliness, percentage of grain not threshed, percentage of scattered grain, threshing efficiency, percentage of yield loss, fuel consumption, and increase in cracked grain. The test sample used was IR 64 rice. Based on the test results, the rotational speed of the thresher cylinder has a very significant effect on the threshing performance of the mini power thresher. Changes in threshing cylinder rotational speed from 669 rpm to 778 rpm can improve the performance of the mini-power thresher in terms of feed capacity, threshing capacity, threshing cleanliness, percentage of grain scattered, and percentage of yield loss. The decrease in performance is found in fuel consumption and the percentage of cracked grain. The variables that relatively unchanged were the percentage of grain not threshed and threshing efficiency. The operation of this mini power thresher is recommended at a thresher cylinder rotational speed of 778 rpm.

Abstract

Bubur pedas is a traditional food from Sambas Regency which is very popular in West Kalimantan. The development of bubur pedas was carried out by making instant bubur pedas so that this food can be enjoyed anytime and anywhere. The main problem found in the production process is in the drying process of raw materials. Based on these problems, it is necessary to develop a drying system to help the instant bubur pedas production process. Through this research, a performance test of a rotary drum type dryer was carried out to analyze the water content and drying rate of instant bubur pedas raw materials. The raw materials for dried instant bubur pedas are katuk leaves, singkil leaves and fern leaves. The rotary drum type dryer is operated at a rotational speed of 14.5 rpm. The drying process takes 2 hours with data collection every 20 minutes. Based on the measurement results, the initial water content of katuk leaves was 76.66%, singkil leaves were 72.72% and fern leaves were 88.06%. After drying for 2 hours, the water content of katuk leaves dropped to 38.40%, singkil leaves 43.91%, and fern leaves 64.64%. The material that experienced the highest decrease in water content was katuk leaves at 38.26%, followed by singkil leaves at 28.81% and fern leaves at 23.42%.

Abstract

The main problem faced by the instant bubur pedas business unit is the filling of pasta seasoning in the packaging. The packaging of seasoning paste is currently done manually by putting the seasoning paste into the plastic packaging using a spoon. The weakness of the manual filling technique was that it has a small filling capacity and needs to be more practical and hygienic. Through this research, an effort was made to overcome these problems by creating a semi-automatic pasta seasoning filling system. This research aims to conduct performance tests on a semi-automatic pasta seasoning filling machine for instant bubur pedas and analyze the relationship between the rotation of the stepper motor and the mass of pasta seasoning coming out of the filling machine. The performance test carried out on the machine is in the form of an analysis of packaging time and packaging capacity. The independent variable was the number of stepper motor revolutions, ranging from 1 to 20. Based on the performance test results, the highest packaging capacity was obtained at 208 packs/hour in the treatment of stepper motor rotation one time, with the number of spices released at 3.29 grams. Increasing the mass of packaged spices requires more stepper motor revolutions, increasing the time needed for each packaging cycle. The stepper motor rotation and the mass of seasoning paste coming out of the filling machine show a consistent linear relationship with a coefficient of determination (R2) value of 0.9983. These results show that this machine can maintain the consistency of the mass of seasoning released per stepper motor rotation.
