Published: May 2024

Abstract
Aloe vera powder is known to offer health benefits and possesses inherent antioxidant properties. However, the powder shows hygroscopic characteristics and causes a decrease in antioxidant activity. Implementing appropriate packaging measures to safeguard the integrity of the antioxidant activity is essential. In order to assess the antioxidant properties of aloe vera powder’s shelf life and stability throughout storage until it reaches critical conditions, this research was conducted.. A non-factorial, completely randomized design was used with open and closed storage using 0.80 mm polypropylene plastic packaging. Aloe vera powder was stored at 25°C and relative humidity (RH) of 75-80% until the critical conditions were reached at a moisture content of 12.00%. The analysis was carried out periodically for water, phenol, and antioxidant activity to scavenge free radicals DPPH (2,2-diphenyl-1-picrylhydrazyl). The results showed a significant increase in the moisture content during storage and decreased phenol and antioxidant activity. The unpacked powder reached its critical condition after 120 hours, whereas the powder enclosed in 0.80 mm polypropylene plastic packaging required a significantly longer duration of 44 weeks. Therefore, storage without packaging experienced a decrease in phenol and antioxidant activity levels by 88.69% and 91.45% in critical conditions. In the polypropylene packaging, there was a decline in phenol and antioxidant activity levels by 30.49% and 27.94%, respectively.

Abstract
The agricultural sector faces two serious threats: declining production due to agricultural land conversion and water shortages due to global warming. Therefore, an agricultural system that accommodates the use of vacant land and water saving, in this case, urban farming with the use of soil-less media can be applied. In recent studies, both innovations have shown positive results in various commodities but have not been explored much specifically for rice crops. This study observed the effect of soilless media application (mixed water and rice husks media) on the growth of rice. This experiment was conducted in Sumber Jeruk, Jember (altitude 281 m asl, temperature 21-31°C, RH 65-75%), January-June 2022. The experiment used a completely randomized design with two factors and three replications. The first factor was the ratio of water to rice husk (1:0; 4:1; and 8:1). The second factor was rice varieties (Inpari 46, IR 64, and Mapan 05). The combination of Mapan 05 and media ratio 4:1 showed the highest result on shoot fresh weight (351.95 g) and root fresh weight (346.35 g). Meanwhile, the highest number of root length (45.20 cm) was found in the combination of Mapan 05 and media ratio 8:1. Moreover, Mapan 05 (93.94 cm) and Inpari 46 (93.88 cm) showed no significant difference in plant height. It can be concluded that soil-less media 8;1 promotes the highest result on rice plant growth observed.

Abstract
Technological development in the agricultural sector will be able to reduce production costs, especially when fertilizing cultivated land. Watering and fertilizing is one aspect that needs special attention in the agricultural sector. It is important because it can affect plant growth and development. Watering is essential to maintain water availability in the soil and not to disrupt the plant’s metabolic processes. Fertilization must be carried out as needed and at the specified time to increase cultivated plants’ productivity. One technology that can be applied is a system for controlling fertilization automatically. Implementing this automatic fertigation system will make it easier for farmers to fertilize effectively and efficiently. Technological developments have an active role in the efficient use of fertilizer in cultivated plants. This Smart Fertigation System device can help farmers carry out watering and fertilizing cultivated plants. Fertigation itself comes from two words, namely fertilizer and irrigation. This method allows watering and fertilizing to be done simultaneously. Watering and fertilizing carried out simultaneously can be decisive in increasing the growth and productivity of cultivated plants. An important factor that must be considered in the fertilization process is a nutrient solution that is appropriate for the age and type of plant. If the controller detects the volume value is more than the set point, it will automatically turn off the valve and pump motor. From the test results, it was obtained that the output value data was more than the set point of 21.67 mL. This can be caused by the accuracy of the sensor. Delays between controller instructions and actuator responses can also result in differences in watering volume. However, the error value is negligible and tolerable. With a flowmeter sensor, different volumes can be watered according to the age of the plant. It can save more water and fertilizer use compared to using manual cultivation. Watering times can also be done precisely without worrying about forgetting.

Abstract
Public-private partnerships are critical to advancing sustainability in the agricultural sector and increasing global food security. Partnerships are a means of increasing productivity and encouraging growth in the agricultural sector. The Partnership encourages private sector participation to reduce risks that occur in the agricultural sector. The aim of this research is to understand how supply chains are configured, to identify drivers of supply chain partnerships and to synthesize partnership strategies. Currently, agricultural areas in East Java are trying to build sustainable partnerships to improve farmers’ abilities in managing the agricultural sector. By using data from surveys and observations of 50 private companies and 50 farmers spread across the research object locations, it was found that there was quite a significant interaction between intensive coordination, partnership quality, quantity and quality of partners. The mechanisms used in partnerships can encourage sustainable agricultural management. It is hoped that the implementation of these findings can encourage partnerships between the private sector and the public sector to achieve significant development. It is hoped that this partnership can play an important role in addressing agricultural problems. Partnerships are formed to create shared values in the form of an institutional framework to address the root of problems.

Published: May 2024

Abstract
Garlic is a commodity that is highly needed by consumers, both for culinary, health and medicinal purposes. Because of the importance of this commodity, Indonesia has become the largest importer of garlic because its production is unable to meet demand. It is important to identify garlic attributes shapes Indonesian consumers purchase intention so that strategies can be developed to improve the quality of local garlic. This study was conducted specifically to determine the level of importance of several garlic attributes from the perspective of consumers. We conducted an online survey in the Greater Jakarta Area and Bandung, involving 493 respondents, to investigate what attributes they consider when buying garlic, in addition to asking several other descriptive questions. Majority of respondents give a high importance to bulb size, clove size, aroma, colour and price. Meanwhile, for the production location and packaging attributes, the majority of respondents gave a low importance. Our survey results surprisingly showed that more than 70% of respondents did not know where the garlic they consumed was produced. The conclusion from this survey show that physical attributes are still important for Indonesian consumers, so the development of local garlic really needs to pay attention to these physical attributes, for example through breeding programs and cultivation practices that can produce garlic characteristics in accordance with consumer wants.

Abstract
Ensuring the viability of local garlic businesses in Indonesia is contingent on the strategic development of effective marketing approaches. The study aimed to conduct a comprehensive mapping and problem identification analysis within the marketing chain of domestically produced garlic sourced from various production centers across Indonesia. The selection of the respondents adhered to the snowball sampling method. Our investigation uncovered a pattern in Java, where a significant portion of high-quality garlic was predominantly allocated to seed requirements, serving government development programs, and mandatory planting programs for garlic importers. Conversely, lower-quality garlic was channeled into local markets, which in turn shaped consumers’ perceptions of their overall quality. In contrast, East Lombok successfully established a clear delimitation between seed production and garlic cultivation. This demarcation allows for a wide spectrum of garlic qualities in the market, ranging from the best to the lowest. The pattern in East Lombok serves as a potential model for other production centers seeking to ensure the long-term sustainability of the garlic business. By leveraging insights gained from the East Lombok pattern, production centers can improve the accessibility of high-quality local garlic for consumers, thereby reshaping perceptions and fostering the sustained growth of the garlic industry.

Abstract
The research aims to address waste-related issues by producing Cellular Lightweight Concrete (CLC) bricks using fly ash and bottom ash as fine aggregates. The variations used encompass cement, fly ash, bottom ash, and sand compositions. The ratio between cement and fine aggregates utilized is 1:3. The variations in the composition of fine aggregates include P (100% sand), F (100% fly ash), B (100% bottom ash), F1B1 (50% fly ash and 50% bottom ash), F1B2 (33.3% fly ash and 66.7% bottom ash), F1B3 (25% fly ash and 75% bottom ash), F2B1 (6.7% fly ash and 33.3% bottom ash), and F3B1 (25% fly ash and 75% bottom ash). The parameters employed comprise compressive strength testing, density, and water absorption evaluation of the CLC bricks at ages 14, 28, and 35 days, also thermal conductivity at the 35-days sample. The sample age exhibits a proportional relationship with compressive strength and water absorption, while displaying an inverse relationship with density. At the 35-day sample age, the F composition demonstrates the highest compressive strength (14.74MPa) and the lowest water absorption (11%). Meanwhile, the B composition exhibits a compressive strength value of 5.9MPa and the lowest density (1.12g/cm2). Conversely, the P composition showcases the highest density (1.59g/cm2). Density affects thermal conductivity, the lower the density, the lower the thermal conductivity, which means that the heat conductivity will be smaller.
