Published: December 2024

Abstract
Additives are one of the ingredients to speed up the composting process. If chicken feathers are composted, the N is easily lost. In the composting process, additives need to be added. The study aims to determine the best percentage of cocopeat and nano biochar (CNB)-enriched chicken feather compost (CFC) and urea in replacing urea fertilizer in corn growth and yield. This research was carried out using an experimental method with a single factor treatment design arranged in a Completely Randomized Environmental Design. The research was carried out using 3 treatments of combination CNB-CFC and Urea, as followed 75% Urea + 25% CNB-CFC (B), 50% Urea + 50% CNB-CFC (C), and 25% Urea + 75% CNB-CFC (D). These three treatments were compared with two treatments of controls, namely 100% Urea (A) and 100% CNB-CFC (E). The research showed that a combination of urea fertilizer and CNB-CFC could replace 25-100% of N Urea and increase the growth and yield of corn. Of all treatments tested, the best growth and yield of corn was recorded from the application of 100% CNB-CFC. This finding emphasized the potential of CNB-CFC as an eco-friendly substitute for Urea that can be used for corn cultivation.

Abstract
Traditional spices beverages need to be developed to enhance the existency of local product. It is necessary to analyze consumer preference of spices beverage. Different type of spices product can affect different preference based on sensory responses. The objective of the study was to determine the sensory characterization of traditional spices-beverages products. Five commercial samples were used in this study. Data was collected by sensory testing on the attributes of color, aroma, viscosity, taste, aftertaste, and overall using 37 untrained panelists. Sensory testing was conducted to collect data on attributes such as color, aroma, viscosity, taste, aftertaste, and overall perception, involving 37 untrained panelists. Statistical processing of sensory test data involved the application of a normality test, followed by the Kruskal-Wallis test, due to the non-fulfillment of the normality assumption. The research revealed that there are significant differences in the color, taste, and overall liking among the spiced beverage samples. The formulation of ingredients in spiced beverages indicates that consumers tend to favor spice drinks with a red color and a mild taste, often combined with milk and sugar. These results can be used by local producers as a reference in the manufacture of spices beverages products that are in accordance with consumer preference to developed the new product. However, this study only focus on sensory responses. Therefore, future studies were advised to combined sensory attributes and other responses to understand comprehensively.

Published: December 2024

Abstract
The tomato sorting process is essential to post-harvest management, which aims to classify tomatoes according to their ripeness level. Currently, the majority of traders in traditional markets sort the tomatoes manually. This manual sorting process has drawbacks, as human judgment can vary and be subjective, leading to errors in sorting. Moreover, the longer duration of the sorting process results in a decline in tomato quality. This research proposes an automatic sorting solution by designing a prototype for sorting tomato ripeness levels based on color. The prototype integrates the technology of a TCS34725 color sensor and a TCRT5000 infrared sensor. The system shows the ripeness levels of the detected tomatoes on the LCD screen. Afterward, it sorts the tomatoes into separate containers based on their ripeness levels: raw, half-ripe, and ripe. This method ensures that tomato ripeness information is displayed and allows for organized sorting to manage post-processing efficiently. The prototype test results show that the average time needed to detect a tomato is 50 milliseconds (ms). Then, the accuracy of the prototype to classify the ripeness level is 98.67%. However, the sorting accuracy depends on factors like the distance between the object and the sensor, as well as the lighting conditions. These variables notably impact sensor readings in the current system, posing a limitation in this research. Future studies should incorporate adaptive algorithms to improve the system’s performance under varying environmental conditions.

Published: December 2024

Abstract
The supply chain structure of the potato-based food industry in Indonesia is not yet optimal, characterized by problems with the continuity of processed potato production and limited supply of potatoes to certain varieties. Food Loss and Waste of potatoes tends to be high, while food loss and waste mapping along the potato supply chain in Indonesia are not yet available. This study aims to identify the research gap of food loss and waste in potato supply chain, to determine the future research position, and to develop the future research framework. Systematic literature review was conducted to identify the research gap. At first, bibliometric analysis was conducted using Harzing’s Publish or Perish and VOSviewer software to produce the network visualization of research keywords to identify the gaps. Secondly, the most frequent keywords were used as the basis to review the relevant previous studies to determine the future research position. “Sustainability” is the main keyword that appears which has a close relationship with “food supply chain”, “supply chain management”, and “food industry”, while “potato” is not the most frequent keyword. The gap identified is the absence of keywords related to “soft system dynamics”, “food loss”, “food waste”, “food loss and waste”, and “life cycle assessment” which could be a potential novelty. To connect the dots of previous studies and produce a novelty, the future research will be positioned around the topic of sustainable potato supply chain modelling to reduce food loss and waste.

Abstract
Chocolate pralines are complex food products that contain a soft filling that interacts with the chocolate shell. The combination of dark chocolate and ginger used as praline is still not widely found in research and innovation trends in cocoa-derived products. This study can have several implications for sustainability. For instance, understanding the quality attributes of this dark chocolate praline with wedang jahe (ginger) jelly filling encourages the use of sustainably sourced ingredients, optimizes formulations, and minimizes waste in production. Dark chocolate is one type of chocolate that has the highest cocoa content and has a relatively high content of flavonoids and catechins that are rich in benefits. Ginger has an active ingredient of oleoresin, consisting of gingerol, paradol, shogaol, and zingerone, which can be antioxidants. Therefore, using ginger as a filling for dark chocolate pralines improves the functional properties of chocolate products. The purpose of this study was to determine the effect of the concentration of ginger (20, 50, 80%) and variations in the ratio of carrageenan and xanthan gum (1:1, 1:3, 3:1) on the quality attributes, which includes physical, chemical, and sensory properties of dark chocolate praline with wedang jahe (ginger) jelly filling applying a completely randomized design (CRD) with a combined factor treatment. Based on the research results, dark chocolate praline with wedang jahe jelly filling with a concentration of 80% ginger and a ratio of carrageenan and xanthan gum 3:1 is the best formula based on the compensatory model weighting method.

Abstract
California papaya fruit is included in the climatic fruit that experiences a respiration burst that accompanies or precedes ripening, through an increase in CO2 and ethylene so that California papaya tends to have a short shelf life. One of the postharvest handling efforts that can be done is to provide a protective layer or edible coating to extend the shelf life. This study aims to determine the effect of edible coating of sago starch on the shelf life of papaya fruit and to know the best treatment for the shelf life of papaya fruit. This research was conducted using experimental methods, with a single factor treatment design, arranged in a completely randomised design (CRD). This study was conducted with 4 treatments, namely Edible coating of sago starch with a concentration of 5% + Glycerol 5% + CMC 0.5%, Edible coating of sago starch with a concentration of 7.5% + Glycerol 5% + CMC 0.5%, Edible coating of sago starch with a concentration of 10% + Glycerol 5% + CMC 0.5%, Without coating or Control. The results showed that there was an effect of sago starch edible coating on the shelf life of papaya fruit on the parameters of weight loss, hardness, total soluble solids, total titratable acid and respiration rate. Sago starch edible coating treatment with 10% concentration + 5% Glycerol + 0.5% CMC was the best for papaya fruit shelf life. The use of natural edible coatings is expected to increase the shelf life of papaya fruit so that it can help improve food security.

Published: December 2024

Abstract
Sweet corn is a plant that is widely grown in Indonesia because it has advantages over corn in general. Sweet corn is generally grown in monoculture, which has several disadvantages. Sweet corn can be planted intercropping, and cowpea are one plant that can act as an intercrop. This research aims to determine the dynamics of environmental conditions in various proportions of sweet corn and cowpea intercropping populations. This research is an experimental study with a single factor arranged in a complete randomized block design with three blocks as replications. The treatment is the population proportion of sweet corn and cowpea, consisting of 3 proportions, namely 1:1, 1:2, and 1:3. Monoculture sweet corn and cowpea were also planted for comparison. Monoculture sweet corn is planted with a spacing of 75 cm × 25 cm; Cowpea are planted at 25 cm × 25 cm, while intercrops are planted at a spacing according to treatment. Observations were made on light intensity, extinction coefficient, air temperature, air humidity, wind speed, soil moisture, soil temperature, and water content. The results showed that intercropping sweet corn and cowpea with population proportions of 1:1, 1:2, and 1:3 caused a decrease in light intensity, a reduction in wind speed, a decrease in air temperature, and an increase in air temperature and humidity. The population proportion of sweet corn and cowpea 1:3 results in better abiotic environmental conditions. Farmers can use the results of this research if they want to plant sweet corn by intercropping with cowpea with a population proportion of 1:3.

Abstract
Food security is one of the government’s programs for alleviating poverty, which is found in the Decree of the Indonesian Ministry of Agriculture (2018) to develop Food Independent Areas in food-insecure areas. This program is needed because food security is an indicator of a country’s stability. Muntuk Village is an area located in the hills, so if a disaster occurs, there may be obstacles in the distribution of food supplies from the city center. To overcome this, the Muntuk Village government wants to develop agricultural land in Muntuk Village. On this occasion, research was conducted on upland rice, maize, and soybean commodities which are commodities in the Indonesian government program UPSUS PAJALE “Special Efforts to Accelerate Self-Sufficiency in Rice, Maize and Soybeans”. The purpose of this research is to map the land that can be planted with upland rice crops. This research uses a survey method. Location selection was carried out using a purposive method, while representative points were determined randomly based on the slope of the land that can be used for food crops, which is between 0-15%. Data derived from field observations, laboratory analysis, and data from related agencies, then matched the data obtained with the Land Suitability for upland rice soybean crop. For agricultural development of upland rice commodities are in Tangkil, Karangasem, and Seropan III hamlets. Improvements are needed in soil fertility sub-classes, especially increasing available Phosphorus and base saturation. In addition, vegetative and mechanical soil conservation techniques are needed to prevent erosion hazards on the land.

Design and analysis of OAM based UCA for vehicular communications in 6G networks
Authors: Krishna Kishore G , Valli R 
Published: December 2024

Abstract
This article presents the design and experimental validation of a uniform circular array (UCA) of circularly polarized (CP) slot patch antennas for generating orbital angular momentum (OAM) beams at 2.4 GHz. The proposed UCA configuration enables high-purity OAM beam generation with azimuthal symmetry, which is critical for vehicular communication applications. Using left-hand circularly polarized elements and a series-fed network, the UCA achieves precise phase control and minimal side-lobe levels. The antenna was optimized to produce the OAM mode with a topological charge l = 1. Numerical simulations and experimental measurements show that the design offers strong impedance matching and high mode purity, making it suitable for applications requiring conical beam radiation, such as vehicle-to-vehicle communications. The 3D measurements further validate the prototype’s effectiveness in generating OAM beams with symmetric radiation patterns, demonstrating significant azimuthal symmetry and confirming its applicability for dynamic vehicular environments.
