	Effect of Ultrasonication on Some Chemical Properties of Red Ginger (Zingiber officinale var. rubrum) Oleoresin Nanoemulsion Bioactive Compounds Oleh Nurma Pratiwi Nanotechnology has developed in various industrial fields. This encourages innovation in the use of additives such as antioxidants, dyes, flavors, and other active ingredients that can be modified in the form of nanoemulsions. Red ginger contains oleoresin, which has thick properties to form a paste. These properties make oleoresin difficult to mix with food, disperse, hydrophobic and susceptible to the effects of heat and light. One solution to overcome this problem is to convert oleoresin into a nanoemulsion so that it has high solubility, is stable, good bioavailability, and improves sensory properties. One technique for making nanoemulsions is ultrasonication. The high-intensity ultrasonication effect can cause the movement of the oil phase into the liquid phase in the form of droplets, thereby increasing the pressure in the liquid and resulting in the breakdown of the oil droplets into smaller sizes. The purpose of this research was to determine the effect of ultrasonication on some chemical properties of the red ginger oleoresin nanoemulsion bioactive compounds, which includes antioxidant activity, total phenol, gingerol content, and droplet microstructure. The study used a completely randomized design with four treatments based on sonication time. Data from the test results were analyzed using analysis of variance (ANOVA) and Tukey's advanced test. Based on the results of the analysis, it was found that ultrasonication had effect on the red ginger oleoresin nanoemulsion biactive compounds. The best treatment is 90 min of sonication. The antioxidant activity (IC50) was 11.45±3.48 ppm, the total phenolic content was 3342.74±283.00 mg GAE/g, and the gingerol content was 0.33 %. The nanoemulsion droplet microstructure complies with the standard; that is, the particles are in the form of small spheres, like balls, and there are no visible holes or cracks on the surface of the particles.
	The Effectiveness of Red Ginger and Brotowali Extract on Broiler Productivity and Carcass Quality oleh Mutia Rizkia Shaffira The purpose of this study was to analyze the using red ginger and brotowali extract both single or in combined application in drinking water on the productivity and carcass quality in broiler. One hundred unsexed broilers were reared for 28 days. This study used a completely randomized design (CRD) with 4 treatments and 5 replications, each replication consist of 5 broilers placed randomly in each treatment. The treatment were P0 = giving drinking water without adding red ginger and brotowali extract (control), P1 = giving 1% red ginger extract in drinking water, P2 = giving 5.12 g/kg body weight of brotowali extract in drinking water, P3 = giving the red ginger and brotowali extract in drinking water. All broilers were observed for productivity variables including feed consumption, body weight gain, feed conversion ratio, and mortality. Twenty samples were used to measure the observed variables in carcass quality including carcass percentage, abdominal fat, cholesterol, and cooking losses. The results showed that the addition of red ginger and brotowali extracts in drinking water both single or in combined application improved on body weight gain, conversion ratio, mortality, carcass percentage, abdominal fat, and cooking loss significantly (p<0.05). Administration of a combination of red ginger and brotowali extract in drinking water resulted in the best body weight gain (1100.28 g/head), Feed conversion ratio (1.37), carcass percentage (83.58%), abdominal fat percentage (0.56%) and cooking loss (8.56%).
	Effect of Light Spectrum LED Lettuce on IoT-Based Indoor Farming oleh Moh. Haris Imron S Jaya Lettuce (Lactuca sativa L.) is an economically important crop worldwide and one of the most popular species grown in indoor farming. Lettuce's fast growth and cycle make a model plant to study the interaction between plants and light. Light's influence is one of the fundamental environmental factors for plant growth and development. Light-emitting diodes (LEDs) have higher light efficiency and wear efficacy, leading to a reduction in associated heating compared to other artificial lighting sources, such as fluorescent lamps or sodium vapor lamps. This research aimed to determine the morphological response of lettuce by giving an LED light spectrum with a single colour spectrum and IOT-based temperature and humidity monitoring. This research used a students’ t-test with a level of 5% on the mean value of the white light spectrum with a yellow light on lettuce plants. Adding LED light spectrum produces a different response to the morphological parameters. LED spectrum affected the plant height variable, where the provision of a yellow LED light spectrum increased the plant height of lettuce.
	Short communication: morphophysiological response of kaffir lime (Citrus hystrix DC) subjected to defoliation and drought stress oleh Moh Haris Imron S. Jaya Renowned for its leaf-spice attributes, kaffir lime has economic value that is worthy of intensifying amidst environmental threats, such as drought stress. This study aimed to analyze the morpho-physiological traits of kaffir lime in response to defoliation and drought stress. Kaffir lime was subjected to drought, defoliation, and a combination of both arranged in a randomised complete block design. Concerning morphology, defoliated lime produced a new flush that grows like a crown, while drought-treated plants displayed a bent pose with withered, edge-rolled, and drooping leaves. Higher leaf drop incidences were also noticed in drought-stressed plants. A combination of defoliation and drought stress produced severe flushing disruption by reducing 61% flush number, 77% flush fresh weight, and 74% flush dry weight, compared to undefoliated plants in normal irrigated conditions. Regardless of drought stress conditions, leaf production did not show significant differences among all defoliated plants. Defoliated plants maintained their photosynthetic rate and water use efficiency, leading to the absence of bent flush and rolling leaves as morphological markers of drought-treated plants. It is implied that defoliation can be a practical strategy for adapting kaffir lime in a drought environment.
	The Increase in Kaffir Lime Leaf Production Due to Gibberellin Is Diminished by Pruning Oleh Moh Haris Imron S. Jaya Gibberellin regulates the flowering and fruiting response of fruit-oriented citrus, but there are a lack of studies on the methods for boosting the production of leaf-oriented citrus. This study aimed to analyze the effects of exogenous gibberellins and pruning on the leaf production of kaffir lime. Kaffir lime seedlings, grafted into rangpur lime, were arranged in a split-plot design under an open field condition. Four gibberellin concentrations (control, 0.005%, 0.01%, and 0.02%) and two pruning levels (no pruning and pruning at 30 cm main stem) were subjected to selected seedlings. The result showed a contrasting effect between gibberellin and pruning on the plant height and shoot number. Pruning significantly reduced the flush number, flush length, leaf length, leaf area, and leaf weight by 38%, 44%, 17%, 26%, and 28%, respectively. Without pruning, applying 0.02% gibberellin could produce the longest flush, with an increase in the number and weight of leaves by about 77% and 64%, compared with the control, respectively. Multivariate analysis also confirmed the positive effect of gibberellin on leaf production. However, these positive results are diminished by pruning due to limited source capacity, as indicated by the fewer leaves. Future research is required to analyze whether increasing gibberellin concentrations can speed up the recovery of post-pruned kaffir lime.

	Treatment of Seeds Using Essential Oils of Scented Lemongrass, Curcuma xanthorrhiza, and Nutmeg on the Viability of White Corn (Zea mays ceratina L.) Oleh Purwanto Seed is a determining factor in cultivation. To maintain seed quality, it is necessary to have a new breakthrough in seed treatment, namely, the use of plant essential oils. Essential oils contain compounds that can repel, kill, and inhibit the development of destructive pests, chemical and semi-chemical components in the form of pheromones, and allelochemicals. This research was conducted to obtain the concentration of essential oil, which is most suitable as a seed protector, before planting to avoid damaging pests and seed-borne pathogens. The research was carried out at the Plant Laboratory 1 of the Lampung State Polytechnic using a randomized completely block design (RCBD), and a further test of the difference that is least significant (LSD) was carried out at the five percentiles. The concentration of essential oils K1:2%, K2:4%, K3:6%, and K0 : control. K0: control. Each concentration was repeated three times. The concentration of 2% (K2) can potentially protect the seed compared to lemongrass and nutmeg at all three concentrations. The use of nutmeg and citronella essential oils at three concentration levels directly affects germination, as seen from the observed indicators of root length, hypocotyl length, strong normal sprouts, weak normal sprouts, abnormal sprouts and dead seeds. This is thought to be due to their high allelochemical content. However, the essential oils of nutmeg and citronella can still be used as a seed treatment with low concentrations of seeds. It is necessary to carry out a vigour test to determine its effect directly in the field so that the most appropriate concentration and application method are obtained in an effort to minimize the effect of allelochemical content on seed growth but still able to protect seeds from destructive pests during the germination period in the field.

	Comparative study of rice morphological and physiological characteristics of rice grown under organic and inorganic farming Oleh Amad Safrudin Organic farming practices have shown a potential to improve rice yields, aside from the popular conventional ones. This study aimed to comparatively analyze the morpho-physiological characteristics of rice plants grown under organic and inorganic farming. This research was conducted at the Polinela Organic Farm experimental station (5°21'10"S 105°13'43"E, 114 m sea above level), from February to April 2023 using a completely randomized design. The results showed that rice grown organically exhibited a notably higher chlorophyll index and actual water use efficiency compared to those grown inorganically. Conversely, inorganic farming resulted in a greater number of tillers than organic farming. However, there were no significant differences between the two systems regarding CO2 efficiency and plant height. An interesting fact is the improved water use efficiency by organic farming helps rice plants to achieve similar growth performance while requiring less water.
	Vertical Integration Of The Rice Market In Lampung Province Oleh Nazila Rice prices in Indonesia increase in the first quarter of 2024, the price increase occurred for premium and medium quality rice, premium rice reached the most expensive price of IDR 16,410 per kilogram, a jump of 21.3% compared to a year ago. Rice price disparities occur due to weaknesses in the agribusiness structure in Indonesia, obstacles that often arise due to market integration and weak market information. Market integration studies can be carried out through vertical analysis along the rice marketing system from producer to consumer. This research aims to analyze rice market integration at the farmer producer and consumer level in Lampung Province. The data used is secondary data in the form of time series data on grain prices at the producer farmer level and retail rice prices at the consumer level in Lampung Province from 2018 to 2023. The data analysis method uses price correlation analysis, price transmission, and the Index of Market Connection (IMC). The research shows that the trend of retail rice prices and farmers' grain prices has an increasing trend every month. Rice prices at both market levels are positively correlated. The results of the price transmission elasticity analysis indicate that the rate of price change at the farmer producer level is greater than the rate of price change at the consumer level. Rice market integration at the producer and consumer levels in the short term is considered weak. This weak integration relationship shows that the rice market in Lampung Province is less integrated in the short term but is strongly integrated in the long term.

	Optimization of Tetrigona apicalis Propolis Extract using Ethanol Solvent with Shaking Ultrasound Assisted Extraction Method Oleh Syahdilla Anggiva Akhni.R Indonesia as a country with a tropical climate, is famous for its natural wealth and has various kinds of flora and fauna that can be found and utilized. Several herbal products have antioxidant and antibacterial capabilities, one of which is propolis. Bee propolis is a functional food because of its nutrition and contains high levels of bioactive components that help protect health. Raw propolis from farmers needs to be purified before human consumption because raw propolis still contains beeswax, resin, and other impurities. The method used is shaking ultrasound-assisted extraction (SUAE), which produces perfect extraction, higher yield and active content, and a shorter time. The purpose of this research is analyzed optimum conditions for extracted Tetrigona apicalis propolis using the SUAE method in ethanol solvent. The propolis extraction process is that raw propolis is size reduced, then solvent is added and macerated using shaker. Next, the extract is processed with a sonicator, and the extract is filtered. The solvent used is 70% ethanol, and the results of the propolis extract are processed using Response Surface Methodology (RSM). The parameters that were optimized were variations in stirring time of 1-24 hours and ultrasonic process time of 1-20 minutes. The best conditions in the propolis extraction process from the yield response shown were a stirring time of 28.76 minutes and an ultrasonic process time of 23.94 minutes with a yield of 8.735%. Based on statistical analysis using software, stirring time and ultrasonic processing time are factors that have a significant influence on the yield of propolis extract produced. The model used is a quadratic model with R2 0.9452. The yield value of the propolis extract predicted by the software is close to the percent yield value obtained based on experiments carried out with an error value of less than 5%.

	Analysis of National Rice Production Policy Using a Dynamic System Model Oleh Melenia Desi Limited rice production capacity and increasing rice consumption make conditions of food insecurity in the form of insufficient rice stocks inevitable. Good rice management in an area will affect the availability of food to meet the population's food needs. Based on Indonesian rice production data, it can be seen that rice stocks fluctuate from year to year. This research aims to analyze the dynamics of the causal relationship of variables that influence the state of rice production and stocks in Indonesia by using a systems approach and applying dynamic system modeling techniques. In this research, a Causal Loop Diagram (CLD) was created for the rice stock system based on a production sub-system which involves the relationship of 11 variables to produce a model output in the form of rice stock projections in Indonesia for the next 10 year period, namely 2024-2034. Validation of simulation results against actual data in the model using the RMSPE method shows a value of 2.88 percent (<5%) so the data can be said to be valid and accurate. The results of the model simulation based on existing conditions (scenario 0) show that rice production with the highest value occurred in 2019 amounting to 30,098,987.82 tonnes and continued to decline every year until 2038 amounting to 29,208,550.85 tonnes. The decline in production figures was caused by land conversion factors and resulted in a reduction in raw rice fields. The reduction in raw rice fields will certainly result in a decrease in rice production and a decrease in rice stocks in Indonesia in the future. Low planting intensity, namely 1.45, also results in low rice production in Indonesia. This condition can be resolved if the Indonesian Government implements effective policies with the policy option of increasing rice productivity with a minimum target of 61,649,964.08 tons/hectare (optimistic scenario 3).
