Abstract

Temulawak (Curcuma xanthorrhiza Roxb.)  has empirical phenolics and flavonoids which can act as antioxidants. The purpose of this study was to produce tablets of temulawak (Curcuma xanthorrhiza Roxb.) with variations in the addition of maltodextrin concentration and to find the best results. This research was conducted using a non-factorial Randomised Block Design (RBD) with 3 treatment levels, the ratio of maltodextrin to 1:2 (50%), 1:4 (25%) and 1:6 (16.70%).  The results of this study showed that all tablets formed met the requirements of BPOM Number 32 of 2019 such that the tablets must be less than or equal to 10% and all the shaped tablets had a uniform weight. The tablets with 1:2 (50%) treatment had the highest value which was able to produce the highest total mean value of phenolics and flavonoids when compared with 1:4 (25%), 1:6 (16,70%) and control treatments. In a 1:2 (50%) treatment, the total phenolic value was 3.63 mg GAE/g ± 0.09, while the total flavonoid value was 6.11 mg QE/g ± 0.30. Therefore, it can be stated that the maltodextrin concentration treatment with a ratio of 1:2 (50%) was the optimum method for producing temulawak (Curcuma xanthorrhiza Roxb.) tablets in this study.

Abstract

Sanankerto Village has an abundant number of livestock (goats), resulting in a significant accumulation of goat manure, which poses a potential health threat to the residents. To enhance the economic value of goat manure in Sanankerto Village, it is necessary to establish an institution focused on managing goat manure waste from upstream to downstream, namely a farmers' group. This community service program aims to initiate the formation of the Sanankerto Village Farmers' Group, with a focus on organizational quality systems, including vision, mission, objectives, quality policies, organizational structure, task mapping, SOPs, and work instructions (IK). Using the PRA (Participatory Rural Appraisal) method, an agreement was reached between the program implementers and Sanankerto Village officials to establish the farmers' group. Due to time constraints, the reported program for forming the farmers' group covers only the formulation of the vision, mission, objectives, and quality policies. This program successfully formulated the vision, mission, and quality policies of the farming group, although further action is still required for full implementation. Based on the achievements to date, it can be concluded that the establishment of the farming group using the PRA method has successfully raised community awareness of the economic potential of goat manure

Abstract

In this paper, we propose a novel technique for unsupervised change detection dataset derived from a process pasteurization using aluminium plate left and right with frequencies 1kHz, 2kHz, 100Hz, 250Hz images using principal component analysis (PCA) and k-means clustering. The distinct image is partitioned into h × h non-overlapping blocks. orthonormal eigenvectors are extracted through PCA of non-overlapping block set to create an eigenvector space. Each pixel within the distinct image is characterized by a feature vector of a certain dimensionality. This feature vector is obtained projection the distinct image data onto the eigenvector space that has been generated. Change detection is accomplished by dividing the feature vector space into two clusters through the application of k-means clustering with k=2. Each pixel is then assigned to one of these two clusters based on the minimum Euclidean distance between the pixel's feature vector and the mean feature vector of the clusters. Empirical results validate the effectiveness of the proposed approach.

Abstract

The high water content of honey can lead to fermentation and accelerate the deterioration of honey. One way to prevent fermentation in honey is to reduce the water content of honey. There are several ways to reduce the water content of honey, namely through a dehumidifier and evaporation. This study aimed to examine the relationship of reduced water content towards time in between dehumidifier and evaporation processes. The research method uses an exponential equation model to determine the value of the constant (K). The constant value (K) is used to predict the rate of reduction in moisture content between the dehumidifier and evaporation processes. The results showed that the water content value after the dehumidifier and evaporation process had met the International Standard (SI) with a moisture content value of less than 19 %. The initial moisture content of honey before processing was 21.335 %, then after going through the process, the moisture content of honey in the dehumidifier and evaporation processes were 16.397 % and 14.625 %, respectively. The processing time required for decreasing the water content of honey in between dehumidification and evaporation processes also shows a very significantly difference; In the dehumidifier process, the process takes 720 min. While in the evaporation process, it is 50 min. The exponential equation to determine the constant value of K (1/min.) for the dehumidifier is y = 21.262e-0.00037x with the value of regression R2 = 0.9943. While the exponential equation formula to determine the constant value of K (1/min.) in the evaporation process is y = 21.961e-0.007x with the regression value represent R2 = 0.9262

Abstract

Indonesia merupakan negara agraris dengan hasil pertaniannya yang begitu besar, baik dari kategori buah, sayur, umbi, dan lainnya. Melimpahnya produk pertanian dan pemenuhan kebutuhan pangan di Indonesia, menjadikan proses pasca panen menjadi hal yang sangat penting. Hal ini harus dilakukan karena produk pertanian yang baru dipanen mayoritas tidak memiliki umur simpan yang panjang. Dan ketika memasuki musim panen, akan sangat berpengaruh terhadap rantai pasok dan bisa mengakibatkan terjadinya ketidakstabilan harga jual dipasaran. Untuk mengatasi masalah tersebut, maka komoditas pertanian harus mendapatkan perlakuan khusus yaitu salah satunya yaitu melalui proses pengeringan. Pada penelitian ini dilakukan modifikasi alat pengering ERK DMT 2 sebagai pengering serba guna, yaitu dengan membuat prototype pengering menggunakan bahan polycarbonate menggantikan plastik UV pada alat pengering sebelumnya (ERK DMT 1). Tujuannya adalah meningkatkan efisiensi kinerja pengering ERK dan menyempurnakan kekurangan pada alat sebelumnya. Bahan uji yang digunakan adalah ubi jalar ungu yang diiris tipis kemudian dikeringkan menjadi bentuk chips. Hasil modifikasi pengering ERK DMT 2 memiliki dimensi panjang 500 mm, lebar 450 mm, dan tinggi 550 mm. Alat pengering ini dapat tetap digunakan pada saat musim hujan dengan nilai efisisensi sebesar 13-17%, memberikan nilai yang lebih baik daripada pengering tipe DMT 1 yang memberikan efisiensi sebesar 11-42%.

Abstract

Finished leather, a primary material for making shoes, bags, and wallets, is processed through tanning to remove veins and feathers. Liquid waste contains a high demand for chemical oxygen (COD), chloride, chromium, and sulfide that can affect river water quality if not treated further. This research was conducted at PT X in Malang City, where liquid waste treatment using an aerator is considered less effective. The tool used in this study is a jet aerator to increase the spread of oxygen in the aeration process. The study aimed to assess changes in the characteristics of tanning liquid waste (pH, temperature, total suspended solids/TSS), and COD) and the effectiveness of using jet aerators in aeration methods in tanning liquid waste treatment. Aeration is carried out for three days. The treatment carried out is aerator + 15 L (A15), jet aerator + 15 L (JA15), and jet aerator + 20 L (JA20). The data were analyzed using Factorial Complete Randomized Design followed by the Smallest Significant Difference test. pH and temperature have met quality standards, while TSS and COD have not. The results showed that the jet aerator +15 L (JA15) decreased maximum tanning liquid waste characteristics on day 1. In contrast, aerator +15 L (A15) and jet aerator +20 L (JA20) decreased maximum waste characteristics on day 2. The jet aerator+15 L (JA15) treatment provides the highest effectiveness value compared to other treatments. COD decreased 49.2%, and TSS decreased 49.7%.

Abstract

Extraction is one of the important processes for obtaining anthocyanins as natural dyes. The aim of this study is to investigate the performance of the extraction apparatus using ohmic technology to produce anthocyanins. This study used a series of ohmic heating consisting of tubular pipes with a diameter of 6 cm and a length of 5.5 cm with a volume capacity of 100 ml. This extraction machine was completed with two electrodes that each have a thickness of 10 mm. The performance of extraction machines using ohmic technology was analyzed by using various voltages of 20, 30, 40, 50, and 60 Volts/cm. The result showed that the voltage affected the electric current of the machine. The voltage of 60 Volts/cm was able to produce the largest average electric current of 5.28 A with the greatest electric current achievement of up to 6.21 A. The result showed that increasing the voltage during the extraction process reduced the time needed to reach the expected temperature. The fastest time was achieved in the voltage of 60 Volts/cm with an average time of 11.3 seconds. The increased voltage in the extraction treatment also affects the total anthocyanin produced. The highest total anthocyanin was obtained from a voltage gradient of 60 Volts/cm with a value of 288.014 mg/L and a yield of 14.4%.

Abstract

In the field of computer vision, image segmentation using a clustering approach was employed. This non-destructive method was applied to process ohmic heating in honey, aiming to achieve an efficient and time-saving mass production process. The K-means clustering algorithm converted RGB color data to Lab color space for effective segmentation. The validation of outcomes was conducted through the evolution of RMSE values and regression analysis for each frequency. Notably, at a precision frequency of 1 kHz, the results were as follows: RMSE Red 1.4902, RMSE Green 0.7017, RMSE Blue 0.3328, Regression Red 0.0792, Regression Green 0.5782, Regression Blue 0.202, and heat penetration regression 0.658. This proposed method was benchmarked against the conventional heat penetration analysis in ohmic heating.

Abstract

The objective of this research is to determine the impact of temperature gradients and solvent ratios in the evaporative vacuum cooling method on the yield of phenol and flavonoid content in galangal extract; ascertain the impact of these factors on the yield generated by galangal extract; and ascertain the mass balance analysis of materials are the objectives of this study. Throughout the extraction of galangal. The study's findings demonstrated that the evaporative vacuum cooling technique, conducted at 49 ºC and with a 1:1 solvent ratio of 1.4432±0.7317 mg GAE/g, produced the highest total phenol concentration. The three differences in the temperature of the evaporative vacuum produced the total phenol content cooling. The overall phenol content obtained decreases with increasing solvent ratio addition. Although the evaporative vacuum cooling treatment at 45 °C yielded the highest total flavonoid content (1.2418±0.2365 mg QE/g) at a 1:2 solvent ratio, the total flavonoid content varied between the three evaporative vacuum cooling temperature variations. The yield of total phenolic and flavonoid compounds was not significantly affected by temperature gradient adjustments or the ratio of galangal extract to solvent (Sig. > 0.05) in any of the data samples pertaining to phenolic and flavonoid compounds. Keywords: Evaporative vacuum cooling, Flavonoids, Galangal, Phenol.
