Abstract

Organic rice is cultivated without synthetic materials, offering high economic value and health benefits. Supportive biophysical components are essential for optimal growth and improving organic rice productivity. This research aims to identify the biophysical components that contribute to the land's carrying capacity for organic rice growth. The research was conducted in Rowosari Village, Jember Regency, East Java. The study analyzed on-farm activities, including producing organic fertilizers and pesticides, land mapping, agroclimate, and assessing biological components. The results show that biophysical factors significantly influence organic rice growth. Indicators of the success of organic fertilizer produced are N of 0.15%, P of 0.04%, K of 0.22%, and fertilizer pH of 4.98. The qualitative analysis of organic pesticides revealed the presence of secondary metabolites like tannin, saponin, flavonoid, alkaloid, and terpenoid with the code (+++). A high biological diversity was observed, with a Shannon-H index exceeding 1. Additionally, the concentration of organic fertilizers and pesticides significantly increased the number of rice plant saplings during the vegetative phase. The study concludes that the biophysical components of the land provide strong support for the growth of organic rice, demonstrating their vital role in the sustainability and productivity of organic farming systems.

Abstract

Leaves are essential organs in plant physiology as they store unique morphometric information for each variety. The leaf constant is an important parameter because it can be used to efficiently estimate leaf area. This study aimed to identify the leaf constant values of avocado variety Hass and mangosteen variety Kaligesing using digital image processing methods. The research was conducted at the Agrotechnology Laboratory, University of Pekalongan. Leaf images were calibrated and processed using ImageJ software to obtain leaf area values. The leaf constant was found to be 0.722 for avocado and 0.661 for mangosteen. These constants were then used to predict leaf area, which was validated against measured leaf area from digital image processing using statistical analysis. The results showed determination coefficients (R²) of 0,9984 for avocado and 0,9915 for mangosteen, with RMSE, NRMSE, NSE, and d values indicating a very high level of agreement. This study demonstrates that leaf constants obtained through digital image processing can be used to model leaf area accurately, quickly, and non-destructively.

Abstract

Organic farming has become increasingly essential to ensure environmental sustainability and public health. One approach to supporting this practice is using liquid organic fertilizers, which not only enhance soil fertility naturally but also aid in managing organic waste. However, limited knowledge and access to agricultural technology often pose challenges for the Pringsurat Village, Pekalongan Regency community, where most of the population works in the farming and plantation sectors. To address these challenges, a training program on liquid organic fertilizer production was conducted, involving 20 members of LMDH in Pringsurat Village—this community service aimed to enhance participants' knowledge and skills. The methods employed included the dissemination of information and hands-on training in the production of liquid organic fertilizer. The results showed a significant increase in participants' knowledge regarding liquid organic fertilizers in terms of benefits and production techniques. Before the training, most participants lacked sufficient understanding of liquid organic fertilizers; however, over 70% of participants demonstrated improved comprehension after the training. Participants' interest in developing liquid organic fertilizers increased significantly, from 55% before the training to 90% afterward. Despite these positive outcomes, challenges remain in applying this knowledge, particularly related to educational factors and individual perceptions. Therefore, a more intensive and sustained approach is required to ensure the successful adoption of sustainable agricultural technologies within the community.

Abstract

The AquaCrop model is widely used under various agro-ecological conditions to reduce farm water consumption. The study aimed to simulate, validate, and measure the performance of AquaCrop models for canopy cover, biomass and soybean crop yields cultivated within a lysimeter. This research was conducted in the experimental field of the Faculty of Agriculture, the University of Jember, Indonesia (8°09'45.1" S, 113°42'58.2" E, 101 m a.s.l). There are four treatments in 4 lysimeters, namely P1 (irrigation based on recommendation), P2 (irrigation 95-105% FC), P3 (irrigation 75-85% FC) and P4 (irrigation 55-65% FC). The AquaCrop model is calibrated using canopy cover (CC) and then validated to predict the biomass and soybean yield. The experiment revealed that the model simulates better CC, biomass, and soybean yields with full irrigation than deficit irrigation. The performance of the AquaCrop model for soybeans of the Deja 2 variety in predicting CC, biomass, and soybean yield is impressive and reasonable. For the CC we found R2 ranges from 0.956 to 0.995, RMSE 10.389% to 3,293%, NRMSE 0.154% to 0.051%, NSE 0.918 to 0.992, and d 0.980 to 0.998. For biomass the R2 is 0.842, RMSE 0.111 t ha-1, NRMSE 0.017%, NSE 0.712, and d 0.937. For soybeans production the R2 is 0.999, RMSE 0.045  t.ha-1, NRMSE 0.018%,, NSE 0.908 and d 0.970. This study demonstrated that based on WUE, 55-65% FC irrigation is the most efficient application.

Abstract

Durian (Durio zibethinus), particularly the cultivars Monthong and Bawor, is a leading horticultural commodity with high economic value. Accurate leaf area estimation is essential for supporting physiological studies and plant growth modeling. However, conventional measurement methods are often characterized by their slow and destructive nature. This study aimed to analyze and identify the constant (k) values of the leaves of durian cultivars Monthong and Bawor using a digital image processing approach. A total of 40 leaf samples from each cultivar were analyzed. Image acquisition was performed using a smartphone camera, while image processing and leaf area measurement were conducted with the ImageJ software. The leaf constant was calculated as the ratio of the digitally measured leaf area to the product of manually measured leaf length and width. The results showed that the mean leaf constant for Monthong durian was 0.702, while for Bawor durian, it was 0.691. These results exhibited narrow value distributions, devoid of any outliers. The correlation between the measured and predicted leaf area yielded very high coefficients of determination (R² of 0.997 for cultivar Monthong and R² of 0.999 for cultivar Bawor). Further statistical evaluation confirmed that the predictive model had very high accuracy, evidenced by its low RMSE values (≤ 1.059), an NRMSE of 0.01, an NSE of at least 0.997, and a Willmott’s index of agreement (d) of at least 0.999. These results indicate that leaf constant values derived from digital image processing can generate precise leaf area estimates and offer a fast, efficient, and non-destructive alternative to conventional measurement methods. In practical terms, this approach enhances precision agriculture by enabling more accurate monitoring of leaf growth dynamics, which is essential for crop management and yield optimization. This finding presents opportunities for further application across other durian cultivars and the broader adoption of similar methods in other plant commodities within the context of precision agriculture and plant growth modeling.

Abstract

Spirulina sp. is a type of plankton commonly found in pond waters. The purpose of this study is to detect the abundance of plankton and the presence of Spirulina sp. in the pond waters used for cultivating vannamei shrimp (L. vannamei). The research methods employed are descriptive quantitative and qualitative analyses, complemented by dynamic system modeling analysis. The results indicate that the water quality conditions of the ponds are still suitable for shrimp farming, with dissolved oxygen levels ranging from 4.01 to 6.17 mg/L, pH levels from 7.7 to 7.9, salinity at 20‰, temperature ranging from 27.050 to 28.25°C, nitrate levels from 0.01 to 0.15 mg/L, phosphate levels from 0.05 to 0.20 mg/L, and water clarity between 25 and 35 cm. The plankton classification identified includes the class Bacillariophyceae with genera such as Skeletonema sp., Cyclotella sp., Coscinodiscus sp., and Amphipora sp.; the class Chlorophyceae with genera such as Chlorella sp., Oocystis sp., and Chlamydomonas sp.; and the class Cyanophyceae with genera such as Oscillatoria sp., Spirulina sp., and Anabaenopsis sp. The plankton diversity index (H’) ranged from 0.01 to 0.33, and the evenness index (E) ranged from 0.10 to 0.50, indicating that the pond waters are still in relatively good condition with minimal indications of pollution. The abundance of Spirulina sp. ranged from 0.2x10^4 to 0.6x10^4 cells/ml. The dynamic system modeling analysis showed that the abundance of Spirulina sp. in pond waters is influenced by the productivity levels of the waters and the grazing process by organisms. In conclusion, the abundance of plankton found in the ponds ranges from 0.4x10^4 to 1.9x10^4 cells/ml, consisting of 10 genera and 3 classes of plankton. Additionally, Spirulina sp. was found in all three research ponds, with an abundance ranging from 0.2x10^4 to 0.6x10^4 cells/ml.

Abstract

Silvofishery is an aquaculture concept that is integrated with the mangrove ecosystem. The concept of silvofishery cultivation is an environmental conservation model combined with the use of an integrated fish cultivation model. This silvofishery concept is very good to be developed in coastal waters. The hope is that in the future there will be activities to develop field class programs for silvofishery cultivation with various empowerment topics. The aim of this service is to make efforts to increase understanding and insight for fish farmers in Degayu Village regarding the silvofishery cultivation system which is carried out using the field class concept.  The method used is community empowerment through practical education about silvofishery cultivation. Furthermore, in this practice, an impact analysis was also carried out by distributing participant response questionnaires. Next, the data from the questionnaire was analyzed descriptively. The results of the service showed that there was an increase in the ability and insight of fish farmers regarding silvofishery cultivation techniques by 40%, knowledge about feeding management by 80%, knowledge about water quality management by 40% and ability regarding feeding practices by 30%. This means that this silvofishery cultivation field class activity is very progressive in improving the quality of human resources for fish farmers. This silvofishery cultivation field class activity is also interesting enough to increase interest in aquaculture literacy for fish farmers. This cultivation field class model is highly recommended to always be carried out consistently as a form of knowledge transfer effort between practitioners (academics) and the program beneficiary audience. From this service activity it can be concluded that the service activity has had an impact on increasing understanding and insight for cultivators in the technical fields of silvofishery cultivation, feeding management, water quality management, and comprehensive technical feeding practices.

Abstract

The utilization of marine animal waste as a base material for adsorbents has become an increasingly popular research topic across various scientific fields, including chemistry, environmental science, and materials science. Waste from marine animals, such as crab shells, oyster shell, seashell, and shrimp shell, possesses high potential to be processed into adsorbents due to their abundant calcium carbonate, chitosan, and protein content. The use of this waste as adsorbents not only provides a solution to environmental issues related to the accumulation of organic waste but also offers cheaper and eco-friendly alternative for water treatment, air purification, and contaminated soil remediation. Research has shown that marine animal waste-based adsorbents are effective in removing various pollutants, including heavy metals, textile dyes, and hazardous organic compounds. With specific modification techniques, the performance of these adsorbents can be enhanced, making them competitive with commercial adsorbents. Overall, the use of marine animal waste as adsorbents represents an innovative approach that contributes to waste reduction and the enhancement of environmental sustainability.
