AbstractPneumatic conveying recirculate dryer (PCRD) is an artificial drying machine which is suitable for flour drying. Previous research has designed PCRD machine to dry the sago flour. The change of sago flour color in PCRD machine is very difficult to be directly measured during the drying process. The aim of this research was to develop an artificial neural network (ANN) model to predict the color difference (ΔE) between wet sago flour before drying and dried sago flour after drying by PCRD machine. The value of ΔE observation was obtained based on the sago color data calculation. The color of sago flour was measured using a color meter (TES 135A). The observation ΔE data were trained and tested on the ANN model using Graphical User Interface (GUI) application, a neuralnetwork- toolbox-based ANN on Matlab R2014a. The training and testing results of the ANN model showed that the best network structure were 12 input neurons, 5 neurons of the first hidden layer, 5 neurons of the second hidden layer, 1 neuron of the third hidden layer, and 1 output neuron (12-5-5-1-1). The value of MSE obtained by the ANN model structure was 0.0005121 with 16 times epoch. The validity test result showed that the coefficient of determination value for the training process (R2 train) equal to 0.987 and for the testing process (R2 test) equal to 0.976. Meanwhile, the optimization analysis result showed that the value of MSE and MRE were quite small, as well as the MSE and MRE value on each parameter variation. It showed that the ANN model is valid to be used to predict the color difference of sago flour drying on PCRD machine.AbstrakPneumatic conveying recirculate dryer (PCRD) adalah salah satu mesin pengering buatan yang cocok digunakan untuk mengeringkan bahan tepung. Pada penelitian terdahulu telah dirancang mesin PCRD untuk mengeringkan tepung sagu. Pengukuran perubahan warna tepung sagu pada mesin PCRD sangat sulit dilakukan secara langsung selama proses pengeringan. Tujuan penelitian ini adalah mengembangkan model jaringan syaraf tiruan (JST) untuk memprediksi perbedaan warna atau color difference (ΔE) antara tepung sagu basah sebelum dikeringkan dengan tepung sagu kering setelah dikeringkan dengan mesin PCRD. Nilai ΔE observasi diperoleh berdasarkan hasil perhitungan data warna tepung sagu. Warna tepung sagu diukur menggunakan color meter (TES 135A). Data ΔE observasi tersebut dilatih dan diuji pada model JST menggunakan aplikasi Graphical User Interface (GUI) JST berbasis neural network toolbox pada Matlab R2014a. Hasil pelatihan dan pengujian model JST menunjukkan bahwa struktur jaringan yang terbaik adalah 12 neuron input, 5 neuron lapisan hidden layer 1, 5 neuron lapisan hidden layer 2, 1 neuron lapisan hidden layer 3, dan 1 neuron output (12-5-5-1-1). Nilai MSE yang dicapai struktur model JST tersebut, sebesar 0,0005121 dengan epoch 16 kali. Hasil uji validitas menunjukkan bahwa nilai koefisien determinasi untuk proses pelatihan (R2 latih) sebesar 0.987, dan proses pengujian (R2uji) sebesar 0.976. Sedangkan hasil analisis optimasi menunjukkan bahwa, nilai MSE dan MRE yang dihasilkan cukup rendah, begitupula nilai MSE dan MRE pada setiap parameter variasi. Hal ini menunjukkan bahwa model JST tersebut valid digunakan untuk memprediksi color difference pengeringan tepung sagu pada mesin PCRD.

There are losses of production due to oil palm field’s material handling. Activities that may raise the losses are harvesting and transportation, which may cause bruise and damage to fruit. This research was aimed to learn the bruise of fresh fruit bunch (FFB) phenomenon in harvesting and transportation. Method used in this research was measuring the bruise area resulted by FFB falling when harvested, loading (throwing up) FFB to truck bin, and transporting using truck. These data, coupled with weight of bruised fruit, were calculated to get FFB bruise index. Each FFB bruise index is related to potential free fatty acid (FFA) value. FFA is one of important quality indicator of crude palm oil. The harvesting was conducted at mineral land and peat land, and the loading and transportation was conducted using wooden board truck and dump (iron board) truck. There was a difference between bruise index and FFA of FFB fall on mineral and on peat land. FFA of mineral land harvesting was 2.19% while of peat land was 1.27%. It was obvious that fruit quality degradation was higher when FFB positioned at the bottom of bin truck layer rather than at the top. FFA of truck bin bottom layer was 2.79% while of top layer was 0.64%. It was found that there was a cumulative bruise on FFB within material handling, start from harvesting, loading up to truck bin, and transporting from field to loading ramp.

The inequity of benefits among actors in the Indonesian patchouli value chain has been taking place for decades. This phenomenon has made distillers unable to guarantee the patchouli oil quality, one of the essential things in the global market. The objective of this study was to evaluate effects of modernization of distillation units and applications of a nonlinear return on investment (ROI) equity model to the financial performance of actors in the value chain to help the government together with the actors making the correct decisions and policies in the development of patchouli oil business. The study was done in the Gayo Lues District, Aceh, Indonesia. The findings indicate that the distillers get the least benefits (the lowest ROI) among actors in the Gayo Lues value chain. Moreover, modernization of the distillation units can increase the ROIs of the actors in the value chain. But, to observe how to establish equity among the actors, a nonlinear ROI equity model was developed. To make ROIs of the actors equal, outputs of the model recommend that the ideal patchouli oil share ratio between farmers and distillers is around 3.3 – 3.4: 1. Outputs of the model also suggest that both net gross and profits per kg of medium middlemen should be increased, while both net and gross profits per kg of large middlemen should be decreased.

This study aims to improve the effectiveness and efficiency of the fertilization process of chili plants. The development carried out is esp32 cam which serves to detect chili plants that lack elements. The method used is input of the nutritional needs of chili plants, spray doses of each plant, and a microcontroller to control applicator components such as sprayer pumps, selenoid valve, and esp32 cam. In this liquid fertilizer applicator there are 2 pipes, each pipe has 4 nozzles. The results of laboratory tests show that the discharge of liquid fertilizer sprayed follows the input results of the nutritional needs of chili plants. The discharge released on the PWM sprayer motor varies from 40 to 100% resulting in very different discharge variations in each PWM spray. The efficiency of this VRA-based liquid fertilizer applicator reaches 87% or an increase of about 14.7% from the applicator before development. Regression analysis of dimmer level to spraying discharge showed a function y = 6.3016x + 18.937 with an R 2 of 0.9921. While the regression analysis of the dimmer level of the applicator speed obtained the function y = 94.075x + 20.203 with an R2 of 0.9936.
