Introduction: Kirinyuh leaf is a widely grown plant in Indonesia, containing alkaloids, flavonoids, saponins, tannins, and steroids. Flavonoids are compounds that can capture free radicals or act as natural antioxidants. Effervescent granules can mask the bitter taste and simplify the dissolving process without involving manual stirring. Objective: The purpose of this study was to make and evaluate a formulation of effervescent granules of Kirinyuh leaf extract. Methods: The granule method was carried out by the wet granulation method. Granule evaluation included organoleptic test, water content test, dissolve time test, flow time test, pH test, and hedonic test. Results: Organoleptic test results showed similar granule size, slightly brownish colour, and characteristics of Kirinyuh leaf odour. When examining their quality, the granules produced met the requirements, with moisture content between 0.4% and 0.7%, dissolving time of 30-35 seconds, flow time test of 8-8.5 g/second, and pH of 5.6-5.8; the results of the hedonic test showed that the effervescent granule preparation was much preferred.

Zingiber Cassumunar

Zingiber cassumunar Roxb contains active compounds such as cassumumin AC, cassummarin AC, phenylbutanoid, and (E) -4- (3,4-dimethoxyphenyl) but-3-en-1-ol which has activities as anti-inflammatory, antioxidant and anti-allergenic agents so that they are potentially used as anti-allergies. Zingiber cassumunar Roxb is made into tablet because it has several advantages, which are easy to consume, practical, the right amount, cover the bitter taste and the distinctive smell and its stability is maintained in storage. This study aims to produce Zingiber cassumunar Roxb tablets that have good physical properties by using PVP as a binder. Zingiber cassumunar Roxb extract was made by maceration using 70% ethanol solvent, the tablet was formulated using wet granulation method. Zingiber cassumunar Roxb ethanol extract tablet was formulated in 3 formulas with variations in the PVP FI content of 1%, FII 2.75%, and FIII 4.5%. The resulting granules were tested for physical properties including moisture test, particle size distribution, flow time, stationary angle, bulk density, and compressibility, while the tablets produced were tested for physical properties including organoleptic test, uniformity of size, uniformity of weight, friability, and disintegration time. The results showed that the optimum concentration obtained was at FIII with 4.5% PVP concentration that complied the organoleptic test requirements, uniformity of size, weight uniformity, and fragility of tablets.

Ground Monitoring

A wireless monitoring unit is designed for underground rail vehicles (URVs) in fields of mining engineering and underground construction. The unit consists of transmitting subsystem and receiving subsystem which are connected by using radio-frequency (RF) technique. Transmitting subsystem acquires and transmits the real-time motion parameters and state of a URV. Receiving subsystem transfers the data to ground monitoring station by RS-485 bus based on Modbus protocol. The upper computer in ground monitoring station displays and stores monitoring results of the URV, which enables the staff to obtain the information of a URV in time. Test results prove that the wireless monitoring unit can work steadily.

Abstract Tests were made to study the differential aeration corrosion of zinc in molar NaCl solutions under varying conditions of aeration, pH, and length of test time. Test results led to the conclusion that formation of differential aeration macrocells is due to passivity of zinc on the zones of the specimen where cathodic reduction of oxygen takes place, and that the principal process of corrosion is accompanied by local corrosion processes at the cathodic and anodic areas of the macrocell. With buffered solutions which do not permit the passivation of zinc, distribution of corrosion changes radically, a localized attack taking place at the water level line where the oxygen flux is at a maximum.3.6.2

Simple Numerical Model

During the past decades, many numerical models have been used to predict responses of asphalt mixes under different types of loading. Some of these models were simple due to practicality but overestimated the response of asphalt mixes. On the other hand, sophisticated but effective numerical models have been developed to address the shortcomings of the simpler models, and were used mostly in finite element analysis (FEA). However, these models were complicated and not user friendly. Recently, the approach of the discrete element method (DEM) was adopted. Unlike traditional FEA, DEM can simulate crack propagation by allowing the separation of elements in the simulated models. Understanding these challenges, this study was initiated to investigate the utilization of a simple visco-elasto-plastic model that had been used successfully in predicting deformation in asphalt mixes using the DEM embedded in Particle Flow Code in Two Dimensions (PFC2D) software simulations. Simulation results, when compared to flow time (FT) and number (FN) test results, showed that this model could simulate actual tests, thus predicting deformation of asphalt mixes using the DEM on a larger scale.

The introduction of coronavirus disease (COVID-19) into the human population represents a tremendous medical and economical crisis. The immune system plays a central role in protecting against this novel virus. This activity aimed to empower young generation using participatory learning and action approach to improve their knowledge about medicinal plants that grow in Indonesia and whose anti-inflammatory, antioxidant, immunomodulatory, and antiviral properties. Organoleptic test results showed that Kunyit Asam (consisted of turmeric and ginger) and Tealang (consisted of butterfly pea and lemongrass) were highly favored by panelists. Our results provide valuable information on the medicinal plants used as an immunity booster within the studied community.

This research was conducted in the Seed Technology laboratory and Laboratory of Microbiology, Faculty of Agriculture, University of Nusa Cendana, Kupang, which lasts from September to December 2013 with aims to investigate the influence of substitution of wheat flour with flour suweg the physicochemical properties and organoleptic cake. This study used a completely randomized design (CRD) with 5 treatments, namely substitution suweg flour to wheat flour: 0%, 10%, 20%, 30% and 40%. The parameters analyzed were proximate, softness, porosity, degree of development, test organoleptic colour, flavour, aroma, and texture. Organoleptic data obtained from the 20 panellists and subsequently analyzed by Friedman test, while ANOVA test if there is a real effect then tested further by using DMRT. The results showed that the substitution of different flour suweg provides a very significant effect on water content, fat, ash content, protein, carbohydrate esandtenderness cake. Based on the results of the organoleptic test, cake with flour substitution suweg the colour, aroma and taste of a real significant show, panellists liked the cake substitution suweg 40%, while the texture, the panellists still like to substitution of 40% flour suweg, an assessment of the texture with the highest scores on substitution treatment 10% flour suweg. Organoleptic test and Friedman test results it can be concluded that the cake treatment received a positive response from the panellists was a cake with 40% flour suweg treatment with a total of 66 rankings for colour, aroma as a total ranking of 68, and for a sense of the total ranking of 74. Similarly, some a score on the cake substitution acceptance panellists ranged from 3,1 to 3,4 and the obtained cake was elected with 40% substitution treatment suweg flour.

The organoleptic test of coffee grown in the Toyomarto area aims to determine consumer preferences for coffee grown on the slopes of Mount Arjuna. The two types of coffee that are most in demand in the global market are Arabica and Robusta. When viewed from the level of consumption, around 70% of the world's population are consumers of Arabica coffee, which has a mild and aromatic taste. Meanwhile, the remaining 30% of the world's population are consumers of Robusta coffee, which has a bitter taste and 50% higher caffeine content than Arabica coffee. There is another type that is grown in Toyomarto, namely the Liberica type. Toyomarto Village, which is located in Singosari District, Malang Regency, is located at an altitude of 700-1200 masl. has a fertile soil that makes a specific and unique taste in the coffee that grows around it. Organoleptic testing has been carried out at 2 different locations. The panelists really liked the sour taste of Arabica coffee and the bitter taste of Robusta coffee. Meanwhile, Liberica coffee was less liked by the panelists.
