Abstract

Agricultural companies that produce utilitarian products must prioritize corporate social responsibility (CSR) efforts to uphold their reputation (Rep) and ensure long-term sustainability through superior performance. This study aims to examine the relationship between corporate responsibility and corporate financial and marketing performance, with differentiation strategy (Diff), firm size (FS), internationalization (Int), perceived external pressure (PEP), and altruism (Alt) acting as drivers of CSR initiatives. Employing a quantitative research approach, this study utilized the fuzzy inference system (FIS) to identify the predictive relationships between variables. Purposive sampling was employed to select five legally incorporated agricultural companies in East Java. The findings indicated that, at specific value thresholds, Diff, FS, Int, PEP, or Alt could serve as drivers of CSR efforts and were associated with corporate financial performance (CFP) and corporate marketing performance (CMP) from the perspectives of CSR, Rep, and PEP. The FIS output models, aligned with the proposed hypotheses, demonstrated that certain values of these input variables positively influence the direction of the output variables. Therefore, company policymakers should carefully consider the value levels of these variables and strive to maintain them to enhance CSR efforts and improve financial and marketing performance effectively. These factors were vital for the sustainability of agricultural companies in East Java.

Abstract

The low productivity of soybeans can be overcome by cultivating them on peatlands, accompanied by the provision of indigenous Rhizobium strains derived from peatlands. Isolating Rhizobium sp. from peatlands is believed to enhance soybean productivity on such land. This study aims to determine the effectiveness of local Riau Rhizobium sp. isolates for soybean cultivation in Riau peatlands. Six isolates of Rhizobium sp. were used in this study, obtained from plants growing on peatlands: IIMB4, IIRM1, IIRM2 from the rhizosphere of Mucuna bracteata, and IIRA4, IIRA2, IIRA6 from the rhizosphere of Acacia crassicarpa. The experiment followed a completely randomized design (CRD), with each treatment replicated four times. The treatments included control, commercial Rhizobium sp., isolates IIMB4, IIRA2, IIRA6, IIRM2, IIRA4, and IIRM1. The results demonstrated that all indigenous Rhizobium sp. isolates from peatlands, particularly IIMB4, effectively formed symbiotic associations with soybean plant roots, improving growth parameters and increasing soybean production. Nevertheless, it is also necessary to assess the effectiveness of these Rhizobium sp. isolates on various other leguminous plant species to identify the most efficient symbiotic isolates across different leguminous crops.

Abstract

The pathogen Xanthomonas oryzae pv.oryzae (Xoo) is responsible for rice bacterial leaf blight (BLB), a disease that can significantly reduce rice yield by 60-80%. Xoo can also be transmitted through seeds, making it a seed-borne pathogen. Therefore, it is crucial for farmers to consider environmental factors when storing seeds. This research aims to determine the optimal temperature and packaging for storing rice seeds to prevent Xoo infection. The study employed a split-plot design, where the main plot consisted of two temperature treatments: low (4 ᵒC ± 2 ᵒC) and room temperature (28 ᵒC ± 3 ᵒC). The subplots focused on three packaging types: no packaging as a control, aluminum foil, and polyethylene plastic, resulting in a total of six treatment combinations. Seed pathology testing was conducted using the liquid assay method, while physiological testing utilized the growing on test method. The results revealed that plastic packaging at room temperature provided the most effective treatment for suppressing Xoo, exhibiting the lowest infectivity, number of colonies, and strength vigor index. Conversely, room temperature without packaging demonstrated the highest physiological quality in terms of seed germination and length. However, the temperature and packaging conditions are optimal for the growth of paddy seeds, i.e., at room temperature without packaging.

Abstract

The residual effects of biochar doses on Entisols after five years of application have not received attention. However, there is an assumption that the positive effects of biochar can last longer in the soil. Therefore, field experiments were carried out in polybags to assess the residual impact of applying biochar doses in the fifth year and the addition of urea fertilizer on the growth of red spinach (Amaranthus tricolor) in Entisol. The growing media used in this study was a medium previously used for five years containing biochar in Entisols. This study used a 2-factor randomized block design consisting of residual doses of biochar (3 levels) and the addition of urea fertilizer (2 levels). There was no interaction between biochar and N fertilizer. Application of biochar at a dose of 500 g/polybag gave a better follow-up effect than 250 g/polybag on the growth of red spinach in the fifth year. Chlorophyll content increased with N fertilization. Applying biochar in the fifth year and N fertilization positively impacted the growth of red spinach in Entisol. Spinach yield increased 30% at the remaining dose of biochar 500 g/polybag and 52% with N fertilization. Within five years, using higher doses of biochar and adding urea will result in better growth of red spinach in Entisol.

Abstract

The coverage of Mucuna bracteata D.C. cuttings plays a vital role in their survival percentage, as it helps maintain appropriate humidity and temperature levels. Uncovered cuttings may experience inhibited growth due to their inability to adapt to direct sunlight. Moreover, the acclimatization process following the removal of the cover is crucial before transferring the cuttings to the field. This research aimed to investigate the impact of various coverage durations on the survival rate of Mucuna bracteata D.C. cuttings. The research was conducted in Telaga Said Village, Langkat Regency, Indonesia, using a non-factorial randomized block design (RBD). The treatments included coverage durations of 1 week (L1), 2 weeks (L2), 3 weeks (L3), 4 weeks (L4), and 5 weeks (L5) after the initial covering of the cuttings. The results revealed that a 4-week coverage duration provided an excellent survival rate of 85% for Mucuna bracteata D.C. cuttings, along with the highest average number of leaves, number of tendrils, number of root nodules, average fresh and dry weight of the crown, average fresh and dry weight of the roots, and the highest average root-to-crown ratio. This information is valuable for the successful propagation and establishment of Mucuna bracteata D.C. cuttings, aiding in the efficient cultivation of this species. Further studies can explore additional factors that may contribute to the overall success of Mucuna bracteata D.C. propagation.

Abstract

Porang (Amorphophallus oncophyllus L.) stands as a prominent agricultural product in Indonesia. As the demand for porang continues to grow, it becomes crucial to balance it with the expansion of suitable land for cultivation. The selection of appropriate land for crop planting requires a thorough analysis of land feasibility, commonly known as land suitability assessment. This study aims to evaluate land feasibility, identify limiting factors, and explore potential solutions for sustainable cultivation of porang in Sumberejo Village, Pasuruan, East Java. The research was employed by a matching method for land suitability assessment based on climatic, physical, and chemical data. The development of a land suitability map was achieved through the overlay of various stages using land characteristic information. The findings reveal that the residents' lands fall within the actual land classes of S3 (suitable marginal) and N (not suitable), with base saturation (nr3) and slope (eh) identified as the primary limiting factors. To improve the suitability of the selected lands, several recommendations were proposed, including the implementation of cover crops, terracing practices, and the addition of potassium-rich organic matter derived from bamboo waste. These recommendations have the potential to elevate the land class to S2 (suitable) and S3 (suitable marginal), thereby addressing the identified limitations and promoting sustainable porang cultivation.

Abstract

Sandy soils are known as low-fertility soils due to the soil's limited physical, chemical, and biological properties. Rice husk biochar and clay soil are organic and inorganic materials that can improve soil quality levels. This study aims to improve the chemical quality of sandy soil and shallot crop yields using rice husk biochar and clay. The study was arranged using a factorial randomized block design, with rice husk biochar as the first factor and soil clay as the second factor. Rice husk biochar consisted of four levels, and three levels for clay. The chemical properties of the soil observed included pH, organic-C, cation exchange capacity (CEC), available-P (av-P), and exchangeable-K (K-ex). The yield of shallots was measured as the number of tubers and each tuber's wet and dry weight. The result showed that soil pH tended to vary and decreased from 6.9 in the initial soil to 6.4. Organic-C content increased from 0.11% initial soil to 0.31% and CEC from 6.80 cmolc/kg initial soil to 19.60 cmolc/kg. Av-P and K-ex levels varied and increased, where av-P increased from 97.65 mg/kg of the initial soil to 105.15 mg/kg, and K-ex levels increased from 0.20 cmolc/kg of the initial soil to 0.65 cmolc/kg. The combination of rice husk biochar and clay had no significant effect on the shallot yield. Rice husk biochar and clay could improve the chemical quality of sandy-textured soil. Both rice husk biochar and clay independently increase shallot yields.

Abstract

Tembesu (Fagraea fragrans Roxb) is a valuable woody plant from the Loganiaceae family, utilized in construction and furniture production. Unfortunately, the tembesu population continues to decline due to excessive logging, forest fires, and a lack of cultivation efforts. Planting through seeds takes a long time, making in vitro propagation an attractive alternative. This research aims to evaluate the effect of 6-benzylaminopurine (BAP) in inducing shoots and determine the optimal BAP concentration on tembesu petiole explants in vitro. A completely randomized design (CRD) with six treatment levels (0, 0.5, 1, 1.5, 2, and 2.5 mg/L BAP) and five replications was employed. Despite a 10% shoot formation rate for each treatment, the optimal BAP concentration for callus formation was found to be 0.5 mg/L, with the highest percentage reaching 70%. The results indicate that adding different concentrations of BAP to the Murashige & Skoog (MS) medium was ineffective in inducing shoots in tembesu petiole explants. Therefore, further research and the development of more sophisticated in vitro propagation techniques are necessary to enhance the success of shoot induction in tembesu. It is hoped that this research will serve as a foundation and motivation for subsequent in-depth studies on the in vitro propagation of tembesu, supporting the conservation and development of this plant.

Abstract

Chicken manure compost serves as a valuable source of organic fertilizer. This study aimed to investigate the effects of different combinations of chicken manure compost and bioactivators on soil and plant nutrient content. Additionally, it sought to examine the relationship between fertilizer dosage and soil and plant nutrient levels, as well as determine the optimal treatment combination of chicken manure compost and bioactivator variations at different doses. In this study, the plant used was pakcoy. The study utilized a randomized group design with two factors. The first factor involved different compost types: A1 (chicken manure compost), A2 (chicken manure compost + N21 bioactivator), and A3 (chicken manure compost + local microorganism (MOL) solutions from banana weevil). The second factor encompassed varying doses of organic fertilizer, 5, 10, 15, and 20 tons ha-1, respectively for D1-D4. The findings revealed that composting chicken manure with different bioactivators and doses led to increased soil nutrient levels and noticeable effects on plant nutrient content. However, no interaction was observed among the combined treatments. The treatment combination of chicken manure compost and MOL solutions from banana weevil yielded the highest average plant nutrient content. Applying chicken manure compost with different bioactivators and doses influenced soil nutrient levels.

Abstract

Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources in sustainable agriculture. The objective of the greenhouse experiment was to observe the effect of humic and fulvic acid (humic substances), and biofertilizer on root growth, nitrogen (N) and phosphor (P) of the growing media, populations of N-fixing and P-solubilizing bacteria in the root zone, and yield of strawberry grown in the cocopeat-based substrate. The experiment was set up in a randomized block design consisting of seven treatments and four replications. The treatments included humic acid, fulvic acid, and biofertilizer in single or combined applications. All data were subjected to analysis of variance and followed by Duncan's Multiple Range Test with p<0.05. All treatments received 50% of the recommended dose of NPK fertilizer. The results showed that all treatments did not affect root length and dry weight. Mixed application of humic substances and biofertilizer together with NPK fertilizer increased total N and P as well as the population of N-fixing bacteria in the growth substrate. Still, P-solubilizing bacteria did not grow in the cocopeat-based substrate. Moreover, mixing humic substances and biofertilizer increased strawberries' fruit yield and sweetness levels.
