Abstract

Indonesia is the second largest exporter of peanuts to Europe. One of the export requirements is that exported peanuts do not contain pests and high levels of pesticides. Aphis craccivora Koch. is the main pest in peanuts and controlled generally using pesticides which cause high pesticide levels. The aim of this research is to determine the application technique for biopesticide containing enthomopathogen (Streptomyces sp. and Trichoderma sp.) and chitosan which were expected to control the population of the pest Aphis craccivora and the intensity of plant damage. The research was conducted and designed using factorial completely randomized design where the first factor was application time (before and after pest investment). The second factor was chitosan concentration of 0.6%, 0.9%, and 1.2% in potato-sugar extract solution. Each treatment combination was repeated 4 times. The results obtained that the pre-investment application technique with a chitosan concentration of 1.2% was more capable of incrasing the mortality of the pest A. craccivora by up to 70% and the application of biopesticide before investment with a concentration of 1.2% had a lower level of damage, namely 38.25%.

Abstract

This study aims to determine the response of soybean varieties tolerant to salinity stress and the impact of NaCl on the growth and yield of soybean. The study was completely designed randomly with two factors, repeated four times. First factor was NaCl concentration consisting of four levels (0; 2.5; 5; and 7.5 g/l), and second factor was soybean varieties (Wilis and Anjasmoro). The data obtained were analyzed using ANOVA followed by HSD test of 5%. Observation variables included plant height, number of leaves, number of productive branches, number of pods per plant, and weight of 100 seeds. Results showed that both NaCl concentration and soybean variety had no significant effect on plant height, number of pods, and weight of 100 seeds. The interaction of NaCl concentration and variety significantly affected the number of leaves and the number of productive branches. Results showed that Anjasmoro variety with no NaCl (0 g/l) treatment revealed the highest number of leaves, namely 5.50 strands. Whiles, the combination of 7.5 g/l NaCl and Wilis variety produced the highest productive branches, namely 4.25 branches. The results of this study are to provide information on the use of saline land in soybean plants by knowing the resistance of soybean varieties to salinity.

Abstract

Land is an important part of the watershed because it is where the hydrological process occurs. There are several problems that can lead to land damage, especially in the downstream area of the watershed, precisely in the Manten Sub-watershed because it has the potential to become critical land. Therefore, this research was conducted with the aim to overcome the existing problems, it is necessary to identify the standard of land degradation in the Manten Sub-Watershed area in accordance with PP No. 150 of 2002. Manten sub-watershed covers 4 sub-districts namely Wajak, Poncokusumo, Tajinan, and Bululawang. Land use in Manten sub-watershed is divided into 3, namely rice fields, kailyards and fields. Based on the results of the analysis of all land use in Manten Sub Watershed, all parameters that have been observed do not exceed the critical threshold criteria except for the redox parameter has a very low value of <200mV. However, this condition can still be improved with proper management such as improving soil aeration using the addition of organic materials so as to increase oxygen levels in the soil and increase redox values.

Abstract

Aeroponics is cultivation that can produce lettuce optimally. This research aims to obtain the quality and quantity of lettuce using the vertical hexagonal aeroponics method with the influence of planting direction, sunlight and the addition of liquid organic fertilizer. This research used a factorial Randomized Group Design (RAK) and was repeated three times. The first factor is the Ab mix concentration and the second factor is the planting direction. The lettuce yield variables observed were plant length, number of leaves, harvest yield (root length, wet weight, dry weight) and organoleptic tests. The single factor of adding POC to nutrients influenced the variables wet weight, dry weight and root length, whereas the planting direction treatment only affected root length and the interaction of planting direction treatment and adding POC to nutrients affected organoleptic and stem variables. long. The root length parameters of 58.94 cm, wet weight of 90.59 grams, and dry weight of 8.40 grams are the best parameters if POC is added to nutrition, and treatment of northeastern plantings gives the highest root length, namely 68.73 cm.

Abstract

Pedada (Sonneratia caseolaris) has great potential as a source of natural antioxidants. The high antioxidant content in pedada fruit requires an appropriate extraction method so that the extracted antioxidant levels in pedada fruit can be maximally extracted. However, the extraction of active compounds from pedada fruit is often limited by the dense cell structure. Pedada fruit extraction can be done using a modified maceration method with Pulsed Electric Field (PEF) pretreatment, so as to shorten the extraction time and require less solvent in the process. It is expected that PEF can damage the cell structure and increase the solubility of antioxidant compounds in the solvent. The quality of the resulting extracts will be evaluated based on total phenol content, total flavonoids, free radical scavenging activity, and antioxidant compound profile. The best treatment was obtained based on antioxidant analysis of the extraction results, namely at a PEF time of 2 minutes with IC50 DPPH values of 18 ppm, IC50 FRAP 37 ppm, total phenol content of 434 mgGAE/L, and total flavonoid content of 120 mgQE/L.

Abstract

Muddy paddy fields cause the traction performance of conventional traction devices to be suboptimal. Research on the analysis of traction performance on various traction devices is needed. The objective of this research is to design, analyze traction performance, and determine the best design from three models of traction devices, i.e. 1) track type, 2) pedal type, and 3) screw type on deep muddy soil. The research method used in this study is experimental, testing the traction performance of the three models at soil bin in muddy soil conditions at 25 cm deep. The parameters measured during the traction performance test are slip, sinkage, and traction efficiency. The treatment used in this study is a vertical load ranging from 93.2 N to 222.7 N. The best traction device design was chosen using the Analytical Hierarchy Process method. The results show that the traction performance achieved the highest score in determining the best traction device design, with a score of 0.78 (track) for the minimum load, 0.83 (track) for the medium load, and 0.87 (track) for the maximum load. Therefore, the track design was ideal, scoring the highest across all parameters.

Abstract

Edamame soybean cultivation in Indonesia has great potential due to its high nutritional value and increasing market demand. However, the current productivity remains low, thereby hindering commercial development. This study aimed to enhance the growth and yield of edamame soybean plants through the application of Arbuscular Mycorrhizal Fungi (AMF) and bioactive compost charcoal on tidal swamp lands. The research was conducted using a split-plot design consisting of two AMF treatments and four levels of bioactive compost charcoal. The results indicated that the combination of AMF and bioactive compost charcoal significantly increased various growth parameters and yield. Although a dose of 10 ton/ha produced vegetative growth equivalent to that achieved by applying 15 ton/ha corn stalk compost, a dose of 15 ton/ha resulted in more optimal harvest outcomes, with pod numbers reaching 43.22 units per plant, pod weight of 91.67 g per plant, and pod weight of 1.545 kg per plot. Furthermore, the treatment also increased the percentage of AMF colonization in roots as well as phosphorus uptake, which contributed to the enhancement of plant productivity.

Abstract

The application of pure corn flour (100%) as coating material tends to generate a tough texture, thus requiring an alternative formulation to obtain a crispier result. This research aimed to evaluate the physical, chemical, and sensory characteristics, as well as to determine the optimal coating flour composition. The study was carried out using nine formulations, consisting of varying proportions (%) of corn flour, rice flour combined with tapioca flour, and glutinous rice flour. Formulas involved A (60:35:5), B (60:30:10), C (60:25:15), D (50:45:5), E (50:40:10), F (50:35:15), G (40:55:5), H (40:50:10), and I (40:45:15). The findings indicated that incorporating rice flour, tapioca and glutinous rice to the coating flour significantly affected the physical and chemical properties. The proportion of corn flour 50% by adding rice flour and tapioca 35%, glutinous rice flour 15% gave a higher panelist preference value for crispiness, which was 4.36. Glutinous rice flour was able to change the proportion of amylose and amylopectin so that the texture was crispy and not too hard when the product was cooled. The characteristics of the coating flour included viscosity value of 3.29mP, WHC 152.89%, OHC 107.53%, protein 4.50%, starch 69.41%, amylose 18.47%, and amylopectin 50.94%.

Abstract

Irrigation in agriculture uses around 70% of freshwater resources globally, but traditional systems often result in ineffective utilization through rigid schedules or skewed decision-making. This article proposes an improved fuzzy logic controller developed using a Genetic Algorithm (GA) to optimize soil moisture control. The GA optimizes the fuzzy membership functions within 50 generations to enhance irrigation efficiency. Simulation and experimental results show that the fuzzy-GA controller maintained soil moisture at values close to the desired value of 25.1% with lower error rates, saving 858 mL more water than manual irrigation and 16 mL more than conventional fuzzy control. The results confirm the potential of fuzzy-GA systems in optimizing irrigation efficiency and ensuring sustainable use of water in agriculture. The fuzzy-genetic algorithm (Fuzzy-GA) improves fuzzy logic control by maintaining soil moisture at a target level of 25.1%, with a very low steady-state error of 0.03783%.
