Abstract

AbstractIt is very important to know the characteristics of candle nut before designing nut-deshelling machine. This study was conducted to investigate physical and mechanical characteristics of candle nut before analyzing the impact force on the de-shelling process. The result showed that average diameter of candle nut at intercept A (length), B (width) and C (thickness) were 32.55 mm, 29.05 mm and 23.23 mm respectively. The average value of sphericity and roundness of candle nut were 0.86 and 0.65 respectively. At high moisturecontent candle nut had a greater value of compressive strength and resulted a sticky kernel in the shell. Candle nut had 4.96% db moisture content after dried at sun drying for 20 hours. The value of compressive strength from the maximum load during a compression test (rupture force) of candle nut at this moisture content were 1,208 N, 1,198 N and 1,950 N for intercept A, B and C respectively.AbstrakSangat penting untuk mengetahui karakteristik kemiri sebelum mendesain mesin pemecah biji kemiri. Penelitian ini dilakukan untuk mengetahui karakteristik fisik dan mekanik biji sebelum menganalisis gaya tumbukan pada proses pemecahan biji kemiri. Hasil penelitian ini menunjukkan bahwa rata-rata diameter biji kemiri pada intersep A (panjang), B (lebar) dan C (tebal) adalah 32.55 mm, 29.05 mm dan 23.23 mm. Nilai rata-rata kebulatan dan kebundaran biji kemiri adalah 0.86 dan 0.65. Pada tingkat kadar air yang tinggi, kemiri memiliki nilai kekuatan tekan yang lebih besar dan akan menghasilkan inti lengket pada tempurung bagian dalam. Kadar air kemiri mencapai 4.96% bk setelah dijemur di bawah sinar matahariselama 20 jam. Nilai kekuatan maksimum pada saat pemberian uji tekan (rupture force) pada tingkat kadar air tersebut pada intersep A adalah adalah 1,208 N, intersep B 1,198 N dan intersep C 1,950 N.

Abstract

 Diperlukan pengetahuan dasar tentang besarnya energi dan gaya yang dibutuhkan pada proses pemecahan cangkang biji kemiri untuk mendapatkan daging biji kemiri bulat utuh. Penelitian dilakukan dengan metode menjatuhkan biji dari berbagai level ketinggian kemiri dan metode menjatuhkan beban mengenai biji kemiri. Hasil penelitian memperlihatkan bahwa dengan metode menjatuhkan biji kemiri dari berbagai level ketinggian diperoleh bahwa ketinggian optimum untuk memecahkan biji kemiri pada posisi intersep C dengan kadar air 6%  adalah dari ketinggian 9 m dengan gaya sebesar 1,52 N. Sementara dengan metode menjatuhkan beban 209,7 gr mengenai biji kemiri diperoleh gaya 6,52 N dan menjatuhkan beban 182,64 gr diperoleh gaya 6,26 N. Untuk keseluruhan metode dibutuhkan energi sebesar 1 joule untuk memecahkan cangkang biji kemiri.   Basic knowledge about amount of energy and breaking force of the candlenut deshelling process is needed to get a whole round kernel. The study was conducted by dropping the candlenut from various level of height and dropping the load on the candlenut. The result showed that the method of droping candlenut from various levels of height was obtained that the optimum height to break the candlenut in the intercept C position with a water content of 6% was 9 m with a force of 1,52 N. While by dropping a load of 209,7 gr obtained a force of 6,52 N and dropping a load of 182,64 gr obtained a force of 6,26 N. For the whole method an energy of 1 joule is needed to break the shell of the candlenut.

Abstract

Advanced knowledge of candlenut deshelling machine is needed to obtain optimal whole round kernel. The objective of this study was to modify the rotor bar on a candlenut deshelling machine with a ripple mill system. The method was engineering or modification, were made in the form of processes and products. The number of grooves on the rotor bar was modified became 2, 4 and 6. Rotation speed of the rotor bar were varied to 15 rpm, 18.75 and 25 rpm. The number of grooves gave a very significant effect on the capacity of the machine, whole round kernel, broken kernel, sticky kernel and unbroken seeds. The rotational speed of the rotor bar gave a very significant effect on the capacity of the machine, broken kernel, and sticky kernel, and gave an insignificant effect on whole round kernel and broken kernel. Interaction between the number of grooves and the rotational speed of the rotor bar gave a very significant effect on the capacity of the machine and the sticky kernel and insignificant effect on the whole round kernel, crushed kernel and unbroken seeds.

Abstract

The effect of Mt. Sinabung eruption has profoundly affected the quality of fruit and vegetable production, in this context is fruit and vegetables. Fruit and vegetable, carrot, strawberry and pakcoy is kind of fruit and vegetable that is consumed by the community especially the communities surrounding both the mountain ranges and the general medan area. The fruit and vegetable are kinds of climateric and the lifespan must be kept. During the transportation of field to market, there wa both mechanical and physical damage.The damage will obviously harm farmers, merchants, and other marketers. So that hydrocooling is applied as a post harvest treatment. Hydrocooling is done right after the harvest, This prosess extracts heat from fruit and vegetables so that respiration and transpiration can continue for a long time.The lack of farmer understanding for post harvest handling is a major problem. Therefore, farmers in aberastagi will be given education and training about post harvest handling (hydrocooling) so they could understand and self applying that will keep their produce fresh. As for the output of this activity is a simple hydrocooling device designed as a visual aid in training. This hydrocooling equipment can also be a reference to training science for schoolchildren in particular agriculture schools and could be a referenceto researchers and developing them.
