Abstract

Eggs are one of the sources of protein, fat, minerals, and vitamins that are good for the body. Eggs are prone to deterioration in quality caused by physical damage in the form of cracks that can occur during packing, transportation, and storage. One way to prevent damage is by the salting method. Therefore, it is necessary to soak in a salt solution to become salted eggs. The purpose of this study was to determine the effect of the level of salt concentration and temperature during the immersion of eggs in a salt solution to obtain quality salted eggs. The temperatures used in this research of 50ᵒC, 55ᵒC, 60ᵒC, and 65ᵒC, and salt concentrations of 15%, 20%, and 25%. The parameters observed were the measurement of the salt concentration of the salted egg, the changing color in the salted egg yolk, and the taste test for the saltiness of the salted egg. The results obtained by soaking salted chicken eggs at 60ᵒC at a concentration of the salt solution (15%, 20%, 25%) have met the SNI standard quality of 2% because the higher the concentration of salt solution given, the salt content in the egg will also increase. The taste level of saltiness in salted egg chicken obtained an average score of 3 with the taste of egg with salty egg, in which the salt solution increases according to temperature and concentration. The color of the eggs produced at 60ᵒC and 65ᵒC changed from normal yellow to orange-colored yolk eggs. The increase in temperature and the concentration of different salt solutions on the salted egg yolk color is affected by diffusion currents, and It causes the taste of the salted egg to turn salty. Keywords: Chicken Salt Eggs, Salt Solution, Soaking.

Abstract

The multi-purpose animal feed chopping machine is one of the feed chopping tools that many farmers use to help speed up the chopping of raw materials that will be used as animal feed. The chopping machine can be operated optimally if the machine is ergonomic so that it is safe and comfortable to operate. This study aims to analyze the ergonomics of a multi-purpose animal feed chopper in terms of anthropometry, operating workload and the level of work fatigue specifically for the chopper. This research uses quantitative methods which are supported by literature studies regarding the design of creating machine dimensions. The parameters in this study are: (1) anthropometric data consisting of Standing Finger Tip Height (TJUB), Standing Vertical Reach (JVB), and Standing Horizontal Reach (JHB); (2) the recommended weight limit that can be lifted by the operator (RWL), and (3) cardiovascular load (CVL). The research results stated that the height of the chopper hopper (100 cm) was classified as ergonomic because it was still between TJUB (66.10 cm) and JVB (183.95 cm). The operator's position from the hopper should not exceed JHB (66.00 cm). The recommended load limit (RWL) is 5.38 kg. Operation of the machine chopper section does not cause work fatigue with an average CVL of 10.71% (≤ 30%). Keywords: Anthropometry, CVL,  Pulse Rate, RWL, Work Fatigue.

Abstract

The feed given to goats is generally in the form of grass and cocoa pods. The grass that is given directly without being chopped is not eaten as a whole by the goat, but what is chopped first is eaten until it runs out. This service program aims to apply a forage chopper machine for goats at Isbani Farm so that the forage becomes fine in size. The method for reducing or smoothing the size of forage is to use a chopper in the chopping process. This chopper is in the form of two blades mounted on the axle and driven by diesel so that it can rotate and chop forage material. Service activities include problem formulation with partners, preparation of chopper machines, training on the use of chopping machines for partners and program evaluation. Partners are very open in conveying problems and very cooperative in coordinating. The animal feed material chopper machine can be well prepared; covering frame; the chopper and the driving motor. The training and application of the counting machine to partners went well; partners can absorb the knowledge and skills provided by the community service team. Evaluation of the service program went well; partners' knowledge increased by about 45%. It is necessary to conduct training in making silage or durable feed from agricultural waste feed ingredients such as corn stalks, rice straw and cassava leaves. It is necessary to create a sustainable program so that the partner assistance process is sustainable.

Abstract

Honey with coffee flowers nectar is native honey formed from flower nectar. In this investigation, corn syrup and rice syrup, two artificial sweeteners, were utilized as an adulterant. Portable fluorescence spectroscopy and the SIMCA method are the tools and techniques employed. There were up to 20 samples of pure Apis mellifera honey and up to 120 samples of mixed honey (MC), each used twice. Data on the emission spectra, which are excited at a wavelength of 365 nm, were measured over the wavelength range of 300-800 nm. To improve accuracy, sensitivity, and specificity, the original spectral data was altered using a number of pre-treatments. Pretreatment with the original data with smoothing moving average may accurately identify samples and provides 100% accuracy, sensitivity, and specificity. One of the steps of the SIMCA approach, the cumulative PC, has a value of 92%, which indicates that it well explains the variation of the data. The x-loading plot's values are near the peak of the waves at 378 and 460 nm, indicating the existence of phenolic and flavonoid chemicals at those wavelengths. Keywords:   Apis mellifera honey, Corn syrup, Rice syrup, Portable Spectroscopy, SIMCA.

Abstract

Hydroton is a clay-based growing medium used in hydroponic systems with variations in size 1-2.5 cm. In Indonesia, most hydrotons are still imported from other countries. The main purpose of this study was to observe the root growth and production of tomato plants grown on hydroponic systems, static aerated technique (SAT) with variations in hydroton size. This study was designed using a complete random design (CRD) with 4 hydroton size treatments (commercial hydroton as control (H0) and 3 experimental treatment with differences in hydroton size made from a mixture of clay and charcoal husk burn (H1, H2 and H3) and 6 replications in each size treatment so that there are 24 experimental units. On the observation of plant productivity showed different results on the treatment applied, while on the growth of roots did not show different results but the growth of roots on artificial hydroton better than commercial hydroton as a control based on physical roots and trend data. The amount of fruit harvested per plant obtained the best results of 25 fruits in the H3 treatment and the total weight of fruit per plant obtained the best results of 1.055,5 grams in the H3 treatment. The longest root in this study measured 96.6 cm in H0 treatment and the weight of the heaviest root in the net pot is 71,5 grams in H1 treatment while the weight of the heaviest root outside the net pot is 276,6 grams in H2 treatment. Based on the results of this study, the increase in the size of the hydroton is able to increase the production value of tomato plants compared to commercial hydroton and hydroton which are smaller in size.

Abstract

Nori is a popular seaweed-based food made from red algae Porphyra. The demand for nori in Indonesia is increasing, but Indonesia does not have Porphyra as raw material and lacks knowledge to find alternatives. Pakcoy (Brassica rapa L.) is a nutritious vegetable that is rarely developed and has the potential to become an alternative raw material for nori. This research aims to develop nori made from pakcoy with various binders to approach commercial nori products. This study is expected to produce an alternative nori that is easily sourced and cultivated in Indonesia. The research used a Completely Randomized Design (CRD) method with 10 treatment levels, which are combinations of 3 types of binders (CMC, tapioca, and cornstarch) at 3 concentration levels (3%, 5%, and 7%). Pakcoy nori was made through the processes of washing, steaming, ginding, molding, and drying. The results of the study show that the addition of 3% CMC produces pakcoy nori with the most preferred color, aroma, flavor, and crispiness by the panelists. The use of CMC, tapioca, and cornstarch as binders can produce pakcoy nori with characteristics similar to commercial nori. This research indicates that pakcoy nori has the potential to be developed as an alternative raw material for nori using 3% CMC as a binder. Keywords:  Binder, Brassica rapa L., CMC, Nori, Pakcoy, Porphyra

Abstract

Chicken eggs are a food that is very rich in nutrients, including protein (12.8%) and fat (11.8%). The high levels of water, fat and protein in eggs can make them a good medium for bacterial growth. Quality deterioration in eggs can be prevented by using egg preservation methods, namely drying eggs into egg powder or flour. Chicken eggs are still very limited and inefficient processing to be used as salted egg flour. Therefore, it is necessary to conduct research on the manufacture of boiled salted chicken egg flour (Gallus gallus. D). This research was conducted to study the making of boiled salted chicken egg flour and understand the characteristics by taking measurements on whole eggs, egg whites, and yolks using the proximate test method, measurement of fineness, and color test. This research was conducted using a non-factorial Completely Randomized Design (CRD) model consisting of 6 testing factors (T) and (A), namely: T1 whole unsalted chicken eggs, T2 white unsalted chicken eggs, T3 yellow unsalted chicken eggs, A1 whole salted chicken eggs, A2 white salted chicken eggs, and A3 yellow salted chicken eggs. The research results of salted chicken egg flour making is a process that involves drying salted eggs and grinding them into flour form. The preparation of salted egg flour showed that the difference between regular chicken eggs and salted chicken eggs, which resulted, affected the proximate properties and had a noticeable impact on the nutritional composition and physical properties of the egg flour produced, while the moisture content was not significantly different. Keywords: Chicken Egg Flour, Egg Preservation, Proximate Properties, Salted Eggs.
