Abstract
A hydroponic floating system is a working system where a plant is placed in a floating net pot on the surface of water. In hydroponic systems, the content of inorganic fertilizers contained in the media is the main source of nutrients for plants. The use of biological fertilizers is expected to reduce the dose of inorganic fertilizers applied to hydroponic systems. The main objective of this study was to obtain a combination of inorganic fertilizers with Inoculant of Rhizosphere Microbial Consortium (IMR) and biofertilizer which has the most influence on the N content, growth and production of kale plant. There are five different treatments on hydroponic floating system viz 100% inorganic fertilizer (control), 100% inorganic fertilizer + IMR (Pa), 75% inorganic fertilizer + IMR (Pb), 50% inorganic fertilizer + IMR (Pc), and 25% + IMR (Pd), where 100% inorganic fertilizer is equivalent to 10 mL / L and the amount of IMR given to each treatment was 10 ml/L. The method used in this research was descriptive comparative method, using primary data which is then analysed quantitatively such as using graphs, and T-test. The results of the research showed that giving a combination of 100% biological fertilizer and 50% inorganic fertilizer, can reduce the use of inorganic fertilizers by 50%, and gave the best and significant influence on plant height 34.41 cm, leaves as much as 30 strands, root length 24.27 cm, and the harvest weight 80.97 grams. The combination of 100% biological fertilizer and 50% inorganic fertilizer does not give a combination of N content of the kale plant.

Abstract
The cupping test has been widely used to assess the roasting level of coffee to produce high-quality coffee beans. However, the method requires a longer process and sophisticated sensory analysis. The procedure could only be assessed by the certified panellist. Lately, commercial microelectromechanical system (MEMS) technology has been developed, which could be used for building a small spectrometer sensor. This gives the opportunity to adopt bench-top spectrometer sensing into the low-cost portable sensor. This research aims to study the performance test on the C12880MA MEMS sensor to determine the level of roasted coffee. A total of 90 samples from each 30 medium roasting level (Light to Medium, Medium, and Medium to Dark) was prepared. Spectrum data of samples were measured using a C12880MA sensor ranging from 312.162nm to 868.503nm. Linear Discriminant Analysis (LDA) was performed to classify the roasting level. The result showed that both LDA using full-spectrum and interval spectrum gave 100% accuracy with no falsely classified.

Abstract
One of the roles of chitinase is as an antifungal which is widely used as a biocontrol agent for plant diseases caused by pathogenic fungi. Bacillus sp. WS4F has chitinase activity which can inhibit the growth of Ganoderma boninense, a fungus that attacks oil palm and causes basal stem rot (BSR). This study aims to investigate the effect of different substrates on the activity of the chitinase from Bacillus sp. WS4F. Two kinds of substrates i.e. chitin flakes and shrimp shells were used in this study. Enzyme activity of chitinase was analyzed after partial purification of enzyme was performed using ammonium sulfate precipitation followed by dialysis. The highest activity of chitinase was achieved by the substrate using shrimp shells. The ammonium sulfate precipitation (60-80% saturation) 0.0949 U/mL for activity enzyme and 0.2639 mg/mL for protein. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of the enzyme showed a molecular weight of 64.389 kDa.
The role vegetable proteins to stabilize emulsion: a mini review
Authors: Isnaini L , Estiasih T , Suseno S H , Lestari L A 
Published: December 2021

Abstract
The critical aspect in forming emulsion is the selection of the right emulsifier. Emulsifiers are facilitating emulsion formation and promoting emulsion stability. Protein is the emulsifier that is often found in the food industry, because it has an active surface containing a mixture of hydrophilic and hydrophobic amino acids along the polypeptide chains. Protein have emulsification properties due to their amphipathic properties (having hydrophobic and hydrophilic groups) are the properties of proteins as emulsification because these proteins are able to form a layer at the oil-water interface. However, protein-stabilized emulsions are sensitive to charge changes, and proteins tend to diffuse slowly towards the interface compared to emulsifiers with smaller molecular weight. The purpose of this literature review is to determine the ability of vegetable proteins to stabilize emulsions.

Authors: Julianti E , Lubis Z , Yusraini E , Ridwansyah  
Published: December 2021

Abstract
Sweet potato starch processing produces liquid waste and solid waste. Solid waste from sweet potato starch processing contains a high concentration of fiber so that it can be used for making fiber flour, which can be used as material for food fiber fortification in foodstuffs. This study aims to evaluate the characteristics of fiber flour derived from the solid waste of purple-fleshed sweet potato (PFSP) starch processing. Starch processing is carried out using 3 different types of extracting ingredients, namely distilled water, 2000 ppm sodium metabisulfite solution, and 2000 ppm citric acid solution. The results showed that the yield of fiber flour produced was 4.07-5.11%. The resulting fiber flour has soluble and insoluble fiber content between 1.20-1.63 and 13.53-21.91% respectively. The results of this study indicate that fiber-rich flour from the solid residue of PFSP starch processing can be used as a fiber fortification agent in special food products for people with obesity.

Published: December 2021

Abstract
East Nusa Tenggara is one of the provinces in Indonesia that uses corn as staple food. Bose corn is an indigenous cuisine for people on the island of Timor, East Nusa Tenggara province. The corn used as raw material for this indigenous cuisine is generally local varieties. Local varieties of corn contain high amylose, so it takes a long time to cook. Starch modification is an instantization method which can be used to shorten its cooking time. Nixtamalization and pregelatinization are simple starch modification methods that can be applied by the community using a certain level of calcium hydroxide and appropriate cooking times. Bose corn is one of the indigenous cuisine processing products using local raw materials that can be developed as an instant food.

Authors: Kurniawan M , Pramono D , Amalia F 
Published: December 2021

Abstract
Fertilizer is an important part of agriculture. To ease the burden on farmers, the government assists in the form of subsidized fertilizers to farmers. Limited information on the availability of subsidized fertilizer supplies in stores often makes it difficult for farmers to obtain them. Therefore, a traceability information system is needed that can help farmers to obtain information on the availability of these fertilizers. This information system will also help the supply chain of subsidized fertilizers to be more effective and efficient. This research was conducted for one year to study the supply chain traceability process and the development of a website-based subsidized fertilizer information system. The method used in this research is to use the unified modelling language (UML) method. The UML used to design the system consists of use case diagrams, class diagrams, activity diagrams, and sequence diagrams. The traceability system that has been designed is implemented into a website-based information system. This research produces a website-based information system of the supply chain traceability information system for subsidized fertilizers.

Published: December 2021

Abstract
The agri-food supply chain consists of activities in “farm-to-fork” order, including agriculture (i.e., land cultivation and crop production), production processes, packaging, warehousing systems, distribution, transportation, and marketing. Data analytics hold the key to ensuring future food security, food safety, and ecological sustainability. While emerging ‘smart’ technologies such as the internet of things, machine learning, and cloud computing can change production management practices. The current study presents a systematic review of machine learning (ML) applications in the agri-food supply chain. This framework identifies the role of ML algorithms in providing real-time analytical insights to assist proactive data-driven decision-making processes in the agri-food supply chain. It also guides researchers, practitioners, and policymakers on successful management to increase the productivity and sustainability of agri-food.

Published: December 2021

Abstract
Salt is one of the essential commodities in Madura. Still, this commodity is often a problem related to the volume of production that cannot be determined with certainty. Sometimes, the estimation and actual production in the field is much different. The satellite image is a picture of an area photographed by satellite remote sensing of an area according to conditions in the field. Satellite imagery can be used to estimate the area of production of a commodity at a specific location. This study aimed to estimate the total area of salt pond in the Madura Island, specifically Sampang district, using a Landsat 8 satellite image. The method used spectral analysis that extracts multispectral data Landsat 8 to result from different areas. Field observations were conducted to validate the area. The results show that the accuracy of satellite image interpretation of salt ponds and non-salt ponds was 67.5%. Based on the result, it is possible to estimate salt pond area production in the Sampang district using Landsat 8. However, classification results must be improved by using other classification methods.
Life cycle cost (LCC) and the economic impact of the national biofuels development through biorefinery concept and circular economy
Authors: Sasongko N A , Pertiwi G A 
Published: December 2021

Abstract
The challenge in the life cycle costing (LCC) analysis of the national biofuel industry is an economic analysis to determine all production costs incurred by the production process from facility construction to waste management. Regarding the Biofuel Supply Chain, the entire process of producing palm oil biodiesel is divided into three stages: production of fresh fruit bunches (FFB), production of crude palm oil (CPO), and biodiesel. LCC analysis is applied by adding an externality variable, providing comprehensive information on the cost structure of palm oil-based biodiesel production. To determine the total cost of externalities that occur due to biodiesel production, the impacts of land use, social costs and environmental costs such as emissions of air pollutants on palm oil biodiesel are considered. The results show that the LCC analysis applied by adding externality variables provides detailed information about biofuel production costs’ composition and hotspots. It can be used to determine hotspots, streamline production, obtain an overview of the most competitive total production costs, and minimize environmental impacts along its supply chain.

Published: December 2021

Abstract
Cellulolytic microorganism has immense potential due to their cellulase production, enzyme complexity and widespread habitat of life. This study was conducted to obtain microbial cellulase with vast industrial applicability from the coffee industry by-product in East Java, Indonesia. Fifty-four isolates with significant clear zone formation were obtained by Congo red staining in CMC agar plates. Eighteen bacteria, two yeasts and two moulds with high cellulolytic index were subjected to protein content determination as well as reducing sugar analysis in various conditions such as pH, temperature, addition of metal ions, surfactant and inhibitor agent. The specific activity measurements of all the crude enzymes result in the highest value of cellulase activity produced by isolate C12 which was 0.401 ± 0.018 U/mg. This enzyme activity was known to be optimum at 50°C and pH 9. It was also stimulated by K+, Na+, Mg2+, Fe3+, and SDS. However, the enzyme activity was inhibited by EDTA at 10 mM concentration. The use of coffee industry by-products as the source of cellulolytic microorganisms offers a promising approach for its various types of indigenous microorganisms and their unique property of cellulase produced that is useful for industrial application.

Published: December 2021

Abstract
Sires play an important role in improvement of productive qualities of bred livestock. Most researchers and breeders estimate their impact to be at least 90%. In order to evaluate the results of using different Holstein breeding bulls, we compared the productivity of their offspring with the average values for all bulls. The following methods of variation statistics were used: observation, data grouping, and correlation analysis. It was found that the best are the descendants of the bull Estuary 2186 of the Montwick Chieftain line. Besides, Liman 2186 bull’s daughters excelled in high milk fat content - 4.46%. Daughters of Punch 2748 bull of Pabst Governor line were the best in protein content of milk (3.27%). Daughters of Liman 2186 bull had the highest fat and protein yield during 305 days of lactation. It was established that the direction and value of correlation between the main features of milk yield of cows of different lineages have a rather high degree of variation. Presence of positive genetic correlation between milk yield and protein content in milk in some lines of animals enables breeding cows by two traits simultaneously (milk yield and protein content in milk).

Abstract
The study is aimed at the effect substantiation of voluminous heating of the cattle frozen colostrum in the two-resonator installation. The methodology is based on the theory of the electromagnetic field, the laws of thermodynamics and the results of physical modeling. The colostrum dielectric parameters were analyzed in the temperature range from -12 °C to +40 °C. The theoretical studies were carried out for changes finding out in the absorption coefficient of the electromagnetic field and the penetration depth of the electromagnetic waves 12.24 cm long during defrosting/heating of the cow colostrum with the fat content of 6.4%. It is found that the penetration depth of the electromagnetic field into the frozen raw material at negative temperatures range (0.2-1.0 cm) is less than that at the colostrum positive temperatures (1.0-2.17 cm). With such significant difference in the dielectric characteristics of the frozen and thawed colostrum and in their penetration depths of the ultra high frequency electromagnetic field, the rate of their heating is considerably different. The developed continuous-flow ultra high frequency electromagnetic generator contains two voluminous resonators. They provide the colostrum being in different physical states with different doses of the ultra high frequency electromagnetic field exposure.

Published: December 2021

Abstract
Although cooperative movement in Russia has a pretty long history, achieving its proper functioning failed for a variety of reasons. With new support measures in place, namely, to establish a basic infrastructure - since 2015, to acquire assets and farm equipment, agro-processing equipment - since 2019, cooperatives in Russia geared to promoting small farms are expected to flare up. In this context, this paper reviews key statistical indicators of the current structural changes in agro-industry, as well as the health and contribution of small farms to the agricultural industry in general. This work aimed to identify preconditions for Russian farmers to form cooperatives. This is of the utmost importance since small farms produce nearly half of the country’s total agricultural output, own 37% of arable land, 56% of cattle, and ensure a quarter of employment. Through the research, a range of malpractices affecting the progress of small farms has been identified. They are dearth of modern technology, efficient staff, impossibility to invest in working capital, problems with marketing of produced goods, etc. Creating well-functioning agricultural cooperatives will address the above challenges today’s Russian farmers face.

Abstract
The purpose of this study was to determine the role of various LED (light-emitting diode) light units in ensuring high-quality growth and development of plants, as well as to obtain high-quality seedlings of strawberries and ground cover rose. We studied the physiological reactions of garden strawberry (“Melga” variety) and ground cover rose (“Fairy” variety) plants under controlled conditions and obtained the data on the effect of light quality on plant biological productivity, dynamics of growth processes, photosynthesis rate and transpiration. Regardless of the type of studied crops, the tallest plants were obtained under conditions of supplementary lighting by the lamp with blue/green/red ratio in the spectrum 17/29/54 % (option 1) and the lamp with ratio 18/45/37 % (option 2). At the same time, the dry weight of leaves and roots, as well as the biological productivity of strawberry plants in experimental options 1 and 2 exceeded by 41% than in the control plants (under high pressure sodium lamp). For garden strawberry we recommend the LED in the option 2, for the ground cover rose optimal is the option 1.
