Implementation of agricultural insurance for sustainable food crop in Mutiara Timur and Suka Makmur Sub Districts
Authors: Indra I , Ula N , Nugroho A 
Published: June 2023

Abstract
The extreme climate has caused anomaly in rainfall, so there is the potential for floods and droughts to have a direct impact on the agricultural sector, particularly the decline in rice production. To overcome this, the government issued a policy in the form of an agricultural insurance program known as agricultural insurance to protect rice plants from the threat of crop failure. Aceh Province, which is one of the central provinces of lowland rice production in Indonesia, has implemented the agricultural insurance program since 2016, but it did not run smoothly due to several weaknesses of the program. Currently, agricultural insurance programs have developed rapidly, one of which is climate index-based agricultural insurance that can overcome the weaknesses of indemnity-based agricultural insurance. Based on the above background, researchers are interested in studying the Willingness To Join (WTJ) and Willingness To Pay (WTP) of farmers on climate index-based agricultural insurance. The analytical methods used are binary logistic regression analysis, Contingent Valuation Method (CVM), and Heckman Selection Models. The results showed that socio-economic factors namely farmer’s age, experience in rice farming, land area, and income from rice farming had a significant effect on WTJ and WTP agricultural insurance premiums with an average premium was Rp168,667 ha−1 per planting season. There are 2 things that the government needs to do to make the agricultural insurance program more successful. First, the application of cheaper insurance premiums and second, increasing farmers’ knowledge about the insurance scheme through more intensive socialization.

Published: June 2023

Abstract
The consortium of bacteria that inhabit the rhizosphere, acting as plant growth promoting rhizobacteria is known as indigenous rhizobacteria. Rhizobacteria can produce chemical compounds that can protect plants from pathogens and various plant-disturbing organisms. Optimization of the growth and yield of patchouli can be done by utilizing the potential of rhizobacteria derived from patchouli rhizosphere. This study aims to obtain rhizobacteria capable of producing secondary metabolites of HCN compounds, siderophores and chitinolytic enzymes which are thought of as biocontrol agents in plant protection. The soil samples used were taken from patchouli rhizosphere areas in three locations, namely Alue Abed, Aceh Jaya and Krueng Itam and Purwosari, Nagan Raya. The exploration results obtained 4 isolates of rhizobacteria from Alue Abed, Calang, 8 isolates from Krueng Itam, Nagan Raya and 37 isolates from Purwosari, Nagan Raya. Based on the test results of qualitative and quantitative physiological properties, 34 isolates were able to produce HCN, 49 isolates produced siderophores and 42 isolates were able to carry out chitinolytic enzyme activity. Rhizobacteria isolate producing HCN, siderophores and chitinolytic enzymes are potential indigenous rhizobacteria candidates and potential for future testing as bio-protections of plants from pathogen attack.

Published: June 2023

Abstract
The development of the citronella oil agroindustry is facing challenges in terms of quality and limited production capacity, especially in the innovation and value-added sectors. This article aims to measure the level of application of innovation in the citronella oil agroindustry chain, starting from the aspects of cultivation, product handling, refining processes, and marketing institutions, including their effect on production value. This study takes location settings in five sub-districts of citronella oil production centers in Kabupaten Gayo Lues. A survey has been conducted on 40 respondents who were chosen deliberately to understand the general picture of the current production system of the community. To deepen the information, FGD was also conducted with 30 key informants. The results show that the application of innovations and good practices on all production lines from cultivation, post-harvest handling, refining, and marketing is low. So this has direct implications for the low productivity and value of citronella oil products produced. Four main components have the most influence, namely the handling of citronella leaves/leaves as raw materials, the refining process, the sale of citronella oil, and stock handling and marketing partnerships.

Abstract
Sigupai is one of Aceh’s indigenous rice varieties originating from the Southwestern region of Aceh. This variety has advantages in the form of fluffier and good rice cooking performance and fragrant aroma, easy maintenance, and minimal fertilizer requirements. This variety has agronomic characteristics that need to be improved such as a harvesting age of up to six months with high plant stature that makes it easy to fall. A series of breeding processes and analyses have been conducted to improve the performance of this variety by crossing it with IRBB27. The phenotypic characters of the F3 progenies (genotypes T11, T22, and T25) were carried out. The purpose of this study was to identify the phenotypic character of the F3 progenies belonging to (genotypes T11, T22, and T25 ). These genotypes originated from the selected plant in F2 progenies by crossbreed between Sigupai and IRBB27. This research was carried out at the Experimental Farm and Genetics and Plant Breeding Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh, from December 2021 to June 2022. The planting medium used was a mixture of soil and manure with a ratio of 2:1. The seeds planted consisted of F3 progenies (genotype T11, T22, T25, as well as their parents Sigupai, and IRBB27. The results showed that there were 3 plants in the F3 Sg/IRBB27 prospective to be developed. These plants originated from genotype T11 (plant no. 6), genotype T22 (plant no. 6), and genotype T25 (plant no. 2). These prospective progenies have medium harvesting ages ranging from 122-132 DAS, and shorter plant heights compared to their mother parent ‘Sigupai’ (121-127 cm), with their products ranging from 5.13-7.40 tons ha−1.

Authors: Usmadi D 
Published: June 2023

Abstract
Land and forest fire disasters impact humans, biodiversity, and the environment. Identification and distribution of land and forest fire vulnerabilities are essential so that disaster mitigation and management can be fast, precise, and prioritized. The research objectives are to identify land and forest fires that occurred in South Sumatra Province in the 2017–2021 period, to identify environmental and anthropogenic variables that influence the occurrence of land and forest fires, and to map the distribution of land and forest fire vulnerability in South Sumatra Province. Land and forest fires use MODIS Hotspots data for 2017–2021. Prediction land and forest fire vulnerability using maximum entropy (Maxent) with predictive variables are climates, topography, soil, vegetation, and anthropogenic. The accuracy of the maxent model uses the AUC value. The number of hotspots with a confidence level of 70% in South Sumatra Province from the 2017–2021 period was 6,778 hotspots, with the highest number of hotspots occurring in 2019 being 5,826 hotspots. Maximum entropy (Maxent) can predict land and forest fires well in South Sumatra with AUC values of 0.807 (training data) and 0.801 (test data). Soil organic carbon, mean temperature of driest quarter, slope, and distance from rivers are essential variables influencing land and forest fires. The areas of land and forest fires vulnerability in South Sumatra Province are not vulnerable at 35,104 km2 (41.28%), low vulnerability at 26,394 km2 (31.04%), medium vulnerability at 15,413 km2 (18.13%), and high vulnerability at 8,119 km2 (9.55%). The districts/cities in South Sumatra Province with the most expansive areas of medium and high vulnerability are Ogan Komering Ilir, Musi Banyuasin, and Banyuasin districts. Data on land and forest fire vulnerability distribution in South Sumatra can be a reference for all parties in land and forest fire mitigation and prevention activities.

Abstract
This research has the purpose of examining the activities of herbicidal effect of n-hexane, ethyl acetate and methanol extracts of cogon grass (Imperata cylindica L.) on spiny amaranth (Amaranthus spinosus L.) The rhizomes of I. cylindrica were extracted with n-hexane, ethyl acetate, and methanol, in that order. The extracts were tested on A. spinosus at concentrations of 5%, 10%, 15%, and 20%. We applied a synthetic herbicide at a concentration of 0.686 kg (2,4-D at 0.686 kg a.i. ha−1) for positive control, and for negative control, we used water without any chemicals (distilled water). The I. cylindrica extracts affects weed control, leaf area, root length, and shoot and root dry weight of A. spinosus. The application of 20 percent of n-hexane extract was the best treatment in terms of controlling A. spinosus (40.83%), but it was not different from other organic solvent treatments at various concentrations, in contrast to aquades (0.00%) and synthetic herbicides (100%). The n-hexane extract of I. cylindrica showed the strongest herbicide effect on A. spinosus after 28 DAA, while ethyl acetate and methanol showed only minimal herbicide effect. Gas Chromatography-mass spethroscopy (GC-MS) analysis showed that rhizome extracts of I. cylindrica contained 3 key compounds each as under : n-hexane extracts : [phthalic acid (43.30%), dibuthyl phthalate (29.75%), linoelaidic acid (5,93%)]; ethyl acetate extracts : [propanetriol acetate (31.73%), phthalic acid (5.69%), n-hexadecanoic acid (5.39%)]; methanol extracts : [acetic acid (52.95%), acetamide (21.86%), octaethylene glycol monododecyl (11.34%). The n-hexane extract proved promising to control A. spinosus

Published: June 2023

Abstract
The uptake of plant nutrients causes nutritional imbalances in hydroponic recirculating systems. Generally, the biological parameters of nutrition solution systems are regulated by pH and nutrients that affect plant health; thus, they must be monitored and managed. In order to solve this issue, a fuzzy logic-based automated control system for intelligent hydroponics was developed. This paper describes the implementation of fuzzy logic controllers into a hydroponic monitoring system. This method produces a controlled hydroponic system in hydroponics by first gathering hydroponic plant data in real time. The system is created using the following steps: system design, prototyping, testing, and assessment. The system’s input consists of TDS and pH sensors, which are used to detect the plant’s nutrient content and pH. The system’s output is a 4-channel relay coupled to 4 small pumps for raising the pH level (pH up), reducing the pH level (pH down), and delivering nutrition AB mix. The fuzzy inference engine employs a combination of the Min-Max and Mamdani techniques. Defuzzification was performed using the centroid technique. The embedded fuzzy logic library (eFLL) is an auxiliary library used by the Arduino IDE. The developed mechanism makes appropriate selections about the nutrition solution management system and pH level.

Authors: Warzukni W , Jauharlina J 
Published: June 2023

Abstract
This study aims to determine the effectiveness of applying young coconut biochar waste and goat manures to entisol soil on the vegetative growth of tomatoes. The research was conducted at the Biochar Research Center, Agriculture Faculty, Syiah Kuala University, which took place on August to December 2021. This study used a factorial randomized block design consisting of 2 factors. The first factor is treatment of Young Coconut Waste Biochar (B1: control, B2: 18.52 g polybag-1, B3: 37.04 g polybag-1) and the second factor is treatment dose of goat Manure (W), (W1: control, W2: 18.52 g polybag-1, W3: 37.04 g polybag-1 and W4: 55.55 polybag-1). Variables observed in this study were plant height (2, 4, 6, 8 weeks after planting), number of aged branches (2, 4, 6, 8 weeks after planting), net assimilation rate, plant growth rate and relative growth rate. The results showed that the application of young coconut biochar wastes and goat manures had no significant effect on the vegetative growth of tomatoes such as plant height at 4, 6, 8 weeks after planting, number of branches at 4, 6, 8 weeks after planting and net assimilation rate. There was an interaction on plant height at 2 weeks after planting but the application of biochar from young coconut waste and goat manure was not able to increase plant height, while in plant growth rate and relative growth rate the best dose was found in the application of 55.55 g polybag-1 goat manure.

Published: June 2023

Abstract
We report on a multi-dimensionally modulated optical vortex array (MMOVA). First, we propose a modified transform technique of the lattice coordinates, which possesses more modulated parameters. Then, the MMOVA is experimentally generated and the optical vortex (OV) is verified and determined by the interference method. Besides the whole structural transformation of MMOVA, the modulation of local part and even the individual OV are executed, which demonstrate the distinct capacity of MMOVA over that of the existing optical vortex array (OVA). The proposed MMOVA provides a novel scheme to generate OVAs with higher modulated dimensions, which will open up potential applications for multiple micro-particles manipulation.

Authors: Shanmugam Hariharan , Baum Christopher F. , Hawkins Summer Sherburne 
Published: June 2023

Objective
The aim of the study is to examine the associations between mandatory access prescription drug monitoring programs (PDMPs), pain management clinic (PMC) laws, and doctor shopping (DS) laws with adolescent nonmedical use of prescription medications (NUPM).

Methods
We linked 2011–2015 Youth Risk Behavior Survey data on 364,103 adolescents across 40 states with PDMP, PMC laws, and DS laws. We conducted a 2-way fixed effects logistic regression model to examine the associations between state drug laws and adolescent self-reported NUPM.

Results
We found some evidence that implementation of a mandatory access PDMP was associated with a decrease in nonmedical use of prescription drugs at the P = 0.079 level (average marginal effect: −0.017, 95% confidence interval = −0.036 to 0.002), while there were no associations with the implementation of PMC and DS laws.

Conclusions
Our findings suggest that current state drug laws to combat NUPM are inadequate for adolescents.

Authors: Gelbart Ben , Kapalavai Sudeep Kumar , Marchesini Vanessa , Presneill Jeffrey , Veysey Andrea , Serratore Alyssa , Appleyard Jessica , Bellomo Rinaldo , Butt Warwick , Duke Trevor 
Published: June 2023

IMPORTANCE:
Standardized clinical measurements of edema do not exist.

OBJECTIVES:
To describe a 19-point clinical edema score (CES), investigate its interobserver agreement, and compare changes between such CES and body weight.

DESIGN, SETTING, AND PARTICIPANTS:
Prospective observational study in a tertiary PICU of mechanically ventilated children with congenital heart disease.

MAIN OUTCOMES AND MEASURES:
Differences in the median CES between observer groups.

RESULTS:
We studied 61 children, with a median age of 8.0 days (interquartile range, 1.0–14.0 d). A total of 539 CES were performed by three observer groups (medical 1 [reference], medical 2, and bedside nurse) at 0, 24, and 48 hours from enrollment. Overall, there was close agreement between observer groups in mean, median, and upper quartile of CES scores, with least agreement observed in the lower quartile of scores. Across all quartiles of CES, after adjusting for baseline weight, cardiac surgical risk, duration of cardiopulmonary bypass, or peritoneal dialysis during the study, observer groups returned similar mean scores (medical 2: 25th centile +0.1 [95% CI, –0.2 to 0.5], median +0.6 [95% CI, –0.4 to 1.5], 75th centile +0.1 [95% CI, –1.1 to 1.4] and nurse: 25th centile +0.5 [95% CI, 0.0–0.9], median +0.7 [95% CI, 0.0–1.5], 75th centile –0.2 [95% CI, –1.3 to 1.0]) Within a multivariable mixed-effects linear regression model, including adjustment for baseline CES, each 1 point increase in CES was associated with a 12.1 grams (95% CI, 3.2–21 grams) increase in body weight.

CONCLUSIONS AND RELEVANCE:
In mechanically ventilated children with congenital heart disease, three groups of observers tended to agree when assessing overall edema using an ordinal clinical score assessed in six body regions, with agreement least at low edema scores. An increase in CES was associated with an increase in body weight, suggesting some validity for quantifying edema. Further exploration of the CES as a rapid clinical tool is indicated.

Authors: Hechtman Rachel K. , Cano Jennifer , Whittington Taylor , Hogan Cainnear K. , Seelye Sarah M. , Sussman Jeremy B. , Prescott Hallie C. 
Published: June 2023

OBJECTIVES:
Sepsis survivors are at increased risk for morbidity and functional impairment. There are recommended practices to support recovery after sepsis, but it is unclear how often they are implemented. We sought to assess the current use of recovery-based practices across hospitals.

DESIGN:
Electronic survey assessing the use of best practices for recovery from COVID-related and non-COVID-related sepsis. Questions included four-point Likert responses of “never” to “always/nearly always.”

SETTING:
Twenty-six veterans affairs hospitals with the highest (n = 13) and lowest (n = 13) risk-adjusted 90-day sepsis survival.

SUBJECTS:
Inpatient and outpatient clinician leaders.

INTERVENTIONS:
None.

MEASUREMENTS AND MAIN RESULTS:
For each domain, we calculated the proportion of “always/nearly always” responses and mean Likert scores. We assessed for differences by hospital survival, COVID versus non-COVID sepsis, and sepsis case volume. Across eight domains of care, the proportion “always/nearly always” responses ranged from: 80.7% (social support) and 69.8% (medication management) to 22.5% (physical recovery and adaptation) and 0.0% (emotional support). Higher-survival hospitals more often performed screening for new symptoms/limitations (49.2% vs 35.1% “always/nearly always,” p = 0.02) compared with lower-survival hospitals. There was no difference in “always/nearly always” responses for COVID-related versus non-COVID-related sepsis, but small differences in mean Likert score in four domains: care coordination (3.34 vs 3.48, p = 0.01), medication management (3.59 vs 3.65, p = 0.04), screening for new symptoms/limitations (3.13 vs 3.20, p = 0.02), and anticipatory guidance and education (2.97 vs 2.84, p < 0.001). Lower case volume hospitals more often performed care coordination (72.7% vs 43.8% “always/nearly always,” p = 0.02), screening for new symptoms/limitations (60.6% vs 35.8%, p < 0.001), and social support (100% vs 74.2%, p = 0.01).

CONCLUSIONS:
Our findings show variable adoption of practices for sepsis recovery. Future work is needed to understand why some practice domains are employed more frequently than others, and how to facilitate practice implementation, particularly within rarely adopted domains such as emotional support.
