Nutmeg is a source of income for some people in South Aceh, and some types of nutmeg, like mace nutmeg, are of better quality. Mace nutmeg is also an agricultural community with great economic value and benefits for humans, as it can be processed into spices and herbs. A range of products includes nutmeg oil and medicines. The harvesting and drying of mace nutmeg, which is still considered a problem by nutmeg growers, cannot be isolated from the processing of the basic ingredients. The natural process of drying mace nutmeg involves the use of sunshine, which necessitates a considerable drying time. Therefore nutmeg farmers frequently complain of erratic weather, especially during the wet season. The constant rain can cause the mace to rot, causing the nutmeg farming community's revenue to become unstable. Methods and steps of research work starting from the study of literature, determination of design specifications, hardware design, software design, toolmaking, tool testing.Good results were reached with the dryness of the mace nutmeg, which can be adjusted, and without putting into account the weather in the drying process, which is usually done with the heat of the sun, per the results of the testing of the designed tools.The average dryness of mace nutmeg is at a temperature of 45 percent with a time of 4 hours and a capacity of 100 grams; according to the test results of the automatic mace drying machine, it produces 50 grams of dry mace.

Banana Stem

Bananas provide many health benefits because they have enough vitamin A for daily body vitamins. Benefits of bananas are not only found in the fruit alone. Banana stem is rarely used because it is considered not to have more benefits and is only considered as waste. However, banana stem can be transformed into various forms of beautiful crafts and high economic value. Banana banana is dried first before being processed into various handicrafts. The process of drying banana is very dependent on the weather conditions and the heat of the sun. Conventional banana drying process takes approximately 70 hours with a solar temperature of about 40oC. The solution to this problem is, design and manufacture a microcontroller based banana bum dryer using PI control to regulate the temperature and utilize the heater as an alternative heat source. This PI control uses Chien Regulator I and Chien Servo I tuning methods. In this Final Project, temperature and banana moisture content is measured. The control will adjust the exhaust fan when the temperature read by LM35 is displayed on LCD 4x20 for temperature monitoring. To adjust the AC-AC voltage controller voltage on the heater, depending on the angle of ignition of the TCA785 IC. DAC of Microcontroller ATMega16 will convert the digital data released microcontroller into analog voltage. The Kp and Ki values used are Kp = 5 and Ki 0.625 using Chien Regulator I method and Kp = 4,126 and Ki 0.414 using Chien Servo I method The drying process takes 16 hours with water content of 4.76% at ± 65oC using Chien Servo I method because the temperature response is more stable.

The results of studying the morphological and biochemical parameters of plants of sea buckthorn are presented. For the first time, genotypes of sea buckthorn ranked by ontogenetic and morphological characteristics and ecological features (relation to the level of soil moisture and humidity air, providing soil nutrients, its рН, amount and mode of precipitation, lighting, positive and negative temperatures) natural, semi-natural and anthropic coenopopulations genotypes of sea buckthorn be ranked by ecomorphic affiliation to certain climate ecotypes (рolissia, forest-steppe) and subecotypes (western-forest-steppe, northern-forest-steppe, рolissia–forest-steppe, central-forest-steppe). Biotypes, that have been a limited ability to carry soil and atmospheric drought (in which the root system is well developed, ground part with copious leaf cover), selected in natural and semi-natural places of growth appertain tо mesophytes (Ms). The genotypes, selected in catchment areas, the lowlands of Forest-Steppe, Polissia of Ukraine, appertain to mesohygrophytes (MsHg) (by morphological and physiological features characterized by weak drought and heat resistance – 6 points, require sufficient moisture and sufficient provision of organic and mineral substances, are weak frost resistant, but very resistant to temperature changes during the winter). A special group makes up widely ecological flexibility mesophyte plants of sea buckthorn – mesoxerophytes (wfMsKs) – are presented рolissia–forest-steppe subecotype, characterized by wide environmental plasticity, due to the high winter, drought and frost resistance, compared to others subecotype.

Abstract Seaweed Eucheuma sp. is one of the natural resources of Indonesia. Seaweed many processed in dry form after going through a drying process or processed into food ready for consumption. Seaweed is no longer just eaten or used to direct treatment, but can be processed into jelly, Algin, carrageenan (carrageenan) and furselaran (furcellaran) which is an important raw material in the food industry, pharmaceuticals, cosmetics and so on. This plant has an important economic value in various industries such as pharmaceutical, cosmetics, food, textile and paper industries. This study aims to determine the Fixer solution of Tawas, Poly Aluminium Chloride and Kapur Tohor most effective at biopigmen Eucheuma sp. instead of synthetic dyes in textile and determine the best concentration of the solution Fixer Tawas, Poly Aluminium Chloride and Tohor in deciding the color biopigmen Eucheuma sp. instead of synthetic dyes in textiles. This study uses a randomized block design (RAK). This research was conducted by observing and comparing the effect Fixer solution between Tawas, Poly Aluminium Chloride and Kapur Tohor against staining quality biopigmen seaweed Eucheuma sp. instead of synthetic dyes in textiles. Organoleptic test results showed fixation material Poly Aluminium Chloride able to maintain better color than the color produced by the fixation Tawas and Kapur Tohor. Poly Aluminium Chloride fixation material produces a bright brown color, Tawas brown, reddish brown Tohor. The test results of color fastness to rubbing cloth (dry) indicates that the color fastness of the strongest to the weakest sequentially generated from Tawas fixation materials, lime Tohor, Poly Aluminium Chloride, while the test fastness to washing soap and desecration of white cloth from the strongest to The weakest is Poly Aluminium Chloride, Kapur Tohor and Tawas.

Abstract This work aimed to evaluate the effect of carrier agents containing maltodextrin and protein, represented by hydrolyzed collagen on the spray drying process of cocona (Solanum sessiliflorum Dunal), and on the properties of the resulting powders. We used pre-established proportions between the solids of cocona pulp and the carrier agents (P:CA), and among carrier agents themselves, maltodextrin and hydrolyzed collagen, (MD:HC). The process was carried out in a spray dryer at an inlet air temperature of 120 ºC. We prepared twelve feed solutions containing 20% of total solids, with P:CA ratios of 1:3, 1:4, 1:5 and 1:6, and MD:HC ratios of 0:100, 50:50, and 100:0. Solids recovery was obtained for the evaluation of the spray drying process. The cocona pulp powders were analyzed for moisture content, water activity, particle size distribution, mean particle diameter, chemical structure (FTIR) and color. For a P:CA of 1:6, for the sample formulated with hydrolyzed collagen only, solids recovery (96.2%) was much higher than that of the sample with maltodextrin only (39.2%). The chemical structure of cocona powders can be considered a sign of a good encapsulation process. The color of the cocona pulp powder was similar to that of the carrier agents. The formulation with highest content of hydrolyzed collagen improved the recovery of solids, guaranteed the cocona pulp encapsulation, and obtained fruit powders with bioactive properties.

The economic value of many proteins as food ingredients lies in their functional properties. Those having abilities such as foaming, emulsifying and water-holding are often supplied as dried powders [for example, egg white (albumin) and milk whey proteins]. The drying process, however, can have a great effect on such functional properties through denaturation of the protein. This paper will address some of the issues affecting functionality for spray-dried whey proteins, previ ously concentrated by ultrafiltration. The limiting factor is the outlet air temperature, which should be low enough to prevent denaturation, as the powder experiences a combination of the highest temperature and the lowest moisture content at that stage in the drying process.
