Increasing global population and urbanization demands enhanced food and feed crop production, but due to several reasons, the areas of fertile agricultural lands are reducing worldwide. The market of growing substrates, soil amendments, and improvers still is based on peat extraction and processing. Due to peat's fossil origin, it can be considered environmentally unfriendly and unsustainable. Seeking peat-substituting materials is of crucial importance on a global scale and may become a vitally significant assignment for future generations. The necessity for peat-free soil amendments is also directed by the targets of circular economy and environmental sustainability goals, leading to reducing or abandoning the use of fossil resources and paying attention to waste utilization as secondary raw material. This paper aims to discuss general features of peat-free soil amendments as well as provide efforts into the use of secondary raw materials such as biomass ashes for the elaboration of peat-free soil-improving products. As a case example, may serve a description of the peat-free product made by rotary drum granulation from biomass fly ashes (energy production waste) and local freshwater sediments in a mass ratio mixture of 67:100, optimally applicable for soil improvement at a rate of 50 g L -1 . Besides, regional opportunities in Indonesia and Latvia are referred. It was concluded that peat-free soil amendment elaboration can be better implemented on a regional scale after assessing agricultural needs, soil specifics, and available raw material variety applicable as ingredients in soil-improving products.

Analog rice is a processed rice product produced from non-rice with slightly more carbohydrates than natural rice. Arrowroot (Maranta arundinacea L) can be used as raw material in analog rice, with red seaweed (Gracilaria spp.) are added to increase the fiber content. A disadvantage of analog rice is its bland taste, which can be improved by adding spices and seaweed, expected to increase the functional value. This study aims to determine the effect of the addition of various seaweed pulp concentrations and spice formulations on the characteristics of analog rice. Various formulas of concentrated seaweed pulp (5 g, 10 g, and 15 g) and spice formulations (onion, garlic, ginger, turmeric, and lemongrass) were applied, and a Randomized Block Design with three replications was used. Subsequently, observation variables included analysis of water content, ash, carbohydrate, protein, fat, antioxidant activity, fiber content, water absorption index, color intensity, and sensory evaluation. The data were analyzed by ANOVA and continued according to Duncan's multiple range test. The results showed that all formulas of analog rice produced from arrowroot starch, with the addition of seaweed pulp and spices, fulfill the chemical and physical properties of paddy rice requirements according to Indonesian National Standard No. 6128-2008. With an increasing concentration of the seaweed pulp, the food fiber, and the resistant starch content increased. The antioxidant activity of the analog rice also increased with the addition of spices, which provided a more attractive color and improved the taste and smell.

Abstract. Canning fish is a processed fish product that has gone through a processing stage, packaged in cans and given heat to ripen fish and other fillings and kill spoilage microbes. During the fish canning process there is product damage caused by several factors such as the production process that is not in accordance with the procedures, poor machinery and equipment, and unsupportive environmental conditions. One of the main causes of damage to fish canning products is cans damage which results in products being contaminated with microbes so that the contents of the cans will experience changes in color, taste and odor. Product damage needs to be minimized by carrying out quality control. Product quality is the most important aspect for companies to survive in the midst of competition between companies. One of the efforts that can be used to maintain product quality is the Statistical Quality Control method. This method can be used to analyze, manage and improve non-standard processes using a statistical approach. SQC has the ability to describe process abnormalities, see the pattern of increasing/decreasing processes in the process, so that corrective action can be taken and even preventive action before the problem actually occurs. The purpose of this study was to determine the quality of fish canning products from the level of product damage using the Statistical Quality Control method and to determine the causes of damage to fish canning products. The study was conducted using the Statistical Quality Control method with the stages of making a check sheet, histogram, control chart, and finally making a causal diagram to determine the cause of product damage. Based on the results of the analysis of calculations using the control chart for 26 days of observation, it is known that there is still damage that is outside the upper control limit which indicates a deviation and based on the analysis of the causal diagram of the factors that cause deviations, namely machines, materials, methods, humans and the environment. Keywords: Cause and Effect Diagram, Control Chart, Deviation, Product Damage Abstrak.

Suweg tuber contains very high starch so that it can be used as one of the ingredients for the edible film. The use of a single ingredient from the starch group has a disadvantage because it has a weak and rigid, so it needs to be added ingredients to improve the nature of the edible film, namely by adding beeswax. The addition of beeswax is expected to improve the physical and mechanical properties of the edible film because its hydrophobic nature is a barrier to the loss of steam from products packed by the edible film. This research used a factorial randomized block design using two factors: suweg tuber starch concentration (3%.4%, and 5%) and beeswax concentration (1%.2%, and 3%). Parameters of research included analysis of raw materials in the form of water content, starch content and amylose starch content of suweg tubers whileanalysis edible film included the thickness, transparency, tensile strength, elongation, solubility, water vapor transmission rate and surface structure. The results showed that there was a very real interaction between the addition of suweg tuber and beeswax starch to thickness, elongation, tensile strength, and water vapor transmission rate and there was a real interaction with the transparency and solubility of edible film. The best treatment with near-standard results is edible film with suweg tuber starch concentration 3% (b/ v) and beeswax concentration 1% (b/ v) The surface structure of edible film on starch addition 3% (b/ v) results in a structure that more flat and soft, while the addition of beeswax 1% (b/ v) results in smaller pores.

Red bean starch is a food ingredient that has a high starch content, which can be used as an edible film. Edible films from the starch group still have shortcomings, namely having brittle and stiff properties, so it is necessary to add other materials to improve the properties of the edible film , namely by adding okra gel. The addition of okra gel is expected to improve the physical and mechanical properties of the edible film. The purpose of this study was to determine the interaction with the addition of variations in the concentration of red bean starch and okra gel on the physical and mechanical characteristics of the edible film. This research consists of two research factors. The first factor is the concentration of red bean starch which consists of 3 levels, namely 4%; 5%; 6; (b / b). The second factor was the concentration of okra gel which consisted of 3 levels, namely 3%; 8%; 13% (w / v). The experiment used a factorial randomized block design (RBD). Observation parameters include analysis of thickness, transparency, tensile strength, elongation, water vapor transmission rate and solubility. The results of this study indicate that there is no interaction between the addition of red bean starch and okra gel on thickness, transparency, tensile strength, elongation, water vapor transmission rate and solubility edible film. The best treatment with results that were close to standard was edible film with a concentration of 5% (w / w) red bean starch and 3% (w / v) of okra gel concentration. The results of the best treatment were 0.16 mm thickness, 4.87 MPa tensile strength, 18.02% elongation, 4.73 g / m2/ day WVTR, 45.14% solubility and 3.98 A / mm transparency.
