Abstract

ABSTRACTFinding the appropriate method of fertilizer application to simultaneously enhance farm productivity and ensure ecosystem sustainability has been receiving a lot of attention. A field experiment was carried in the Research Plot Agriculture Faculty Bengkulu University Campus Indonesia in 2017. The purpose of this study was (1) to assess the significant effects of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC) under equal N conditions on growth, N accumulation, and yield of sweet corn, and (2) to determine the appropriate level to which inorganic N fertilizer could be reduced and equivalently replaced by bio-fortified compost to promote sweet corn growth and yield. The treatments consisted of six different proportions of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC). Each treatment was designed on the basis of equal amount of total N input from a combination of both fertilizers (138 kg N ha-1).  They were arranged in a randomized block design with 3 replications. They included (1) 100% IF plus 0% BC, (2) 75% IF plus 25% BC, (3) 50% IF plus 50% BC, (4) 25% IF plus 75%, (5) 0% IF plus 100% BC, and (6) no IF and no BC. The results showed that the increasing proportion of IF replaced by BC resulted in an increase for all variables (except for plant height) but they decreased when 100% IF substitution with 100% BC was applied. Among the partial substitution treatments, 50% IF plus 50% BC consistently produced the best growth, N accumulation, and yield increase. Treatments of 50% IF plus 50% BC and 25% IF plus 75% BC produced the highest green cob weight with husk per plot (10.74 – 10.84 kg plot-1), which was 16% to 19% higher than treatment of 100% IF plus % BC. The three partial substitution treatments produced crop yield components as good as treatment of 100% IF plus 0% BC. Treatment of 0% IF plus 100% BC reduced plant growth, N accumulation, and crop yield and its components. The appropriate level to which IF could be reduced and equivalently replaced by BC was at the range of 25% to 75%. Hence, a suitable replacement of inorganic N fertilizer with bio-fortified compost is considered a reasoned way to simultaneously increase crop yield and reduce environmental degradation.Keywords: organic fertilizer, chemical fertilizer, bio-fortification, chemical fertilizer substitution, bio-fortified compost

Abstract

biodegradable polymer such as PVA is considered the most promising candidates for developing the sustainable sticker. The objective of this study was to determine the most suitable PVA + TS blends as adhesives agent for AMF spores inoculation via seed coating which can enhance the spores viability and their beneficial properties in maize. The polythene bag experiment was performed in a screen house of the Department of Plant Protection Faculty of Agriculture, University of Bengkulu Indonesia in 2015. Six adhesive blends were employed: 100% PVA + 0% TS, 75% PVA + 25% TS, 50% PVA + 50% TS, 25% PVA + 75% TS, 0% PVA + 100% TS, and no coating. The six experimental treatments were laid out in a completely randomized design with three replications. The results show that root colonization, AMF spore population, and shoot dry weight in 75% PVA + 25% TS were equal to those in 100% PVA. Root colonization, AMF spore population, shoot P content, and shoot P concentration were greater for 50% PVA + 50% TS than 100% PVA, 100% TS, and no coating. A mixture of 50% PVA + 50% TS was considered the preferred sticker. Thus, the tapioca starch can be used to substitute 25 - 50% of the PVA used without reducing AMF inoculant adhering to seed.Keywords: polymeric seed coating, seed coating formulation, arbuscular mycorrhizal fungi, sustainable coating adhesive, seed inoculation, seed inoculant

Abstract

Salinity stress is the major abiotic stress for crop production. The purpose of this study was to evaluate the effectiveness of zeolite on improving soil properties, the growth, and yield of Chinese cabbage. This pot experiment was conducted from September to November 2020 at the Research and Teaching Field of the Faculty of Agriculture, consisted of 6 treatment levels, i.e. (1) control, (2) soil + 6.9 g NaCl /10 kg soil, (3) soil + 6.9 g Na2SO4 /10 kg soil, (4) soil + 3.2 g zeolite /10 kg soil, (5) soil + 6.9 g NaCl /10 kg soil + 3.2 g zeolite /10 kg soil, and (6) soil + 6.9 g Na2SO4 /10 kg soil + 3.2 g zeolite /10 kg of soil, and arranged in a completely randomized design with 3 replications. The application of zeolite decreased the EC of salinized soil and increased the soil CEC. NaCl salinity stress reduced plant height (23%), number of leaves (22%), fresh weight of roots (165%), dry weight of roots (170%), stalk length (32%), and plant dry weight (131%), while Na2SO4 salinity stress only reduced the number of leaves (23%). The addition of zeolite to salinized NaCl soil increased stalk length (39%), plant fresh weight (172%), leaf fresh weight (174%), plant dry weight (133%), and leaf dry weight (23%), while to salinized Na2SO4 soil only increased plant dry weight (90%) and leaf dry weight (177%). The overall results show that the addition of zeolite can effectively ameliorate salinity stress due to NaCl.

Abstract

A field trial was conducted to determine the efficiency of AMF inoculation for enhancing growth and yield performance of maize, root colonization, soil available P, and P uptake in Ultisols amended with different P dosages. This experiment was conducted in a 3 x 3 factorial scheme under complete randomized  design with three AMF inoculation methods and three different P levels (0, 60, and 120 kg P2O5 ha-1) in five replications. Data were collected on plant growth, yield parameters, soil available P, P uptake, and root colonization. Results showed that inoculation via seed coating at 60 kg P2O5 ha-1 gave a significant (p<0.05) increase in  growth traits (average of 25%), biomass production, grain yield (average of 30%), soil P availability, P uptake, and root colonization. Inoculation via seed coating combined with 60 produced the same values of all the tested parameters with and seed coating inoculation and soil inoculation at120 kg P2O5 ha-1. Thus, seed coating was as effective tool as soil inoculation for AMF delivery and capable of reducing 50% of P fertilizer use. For these reasons, co-application of P fertilizer and AMF inoculation via seed coating could be practiced to improve corn yields on poor Ultisols.

Abstract

This research aims to determine the revitalization of vocational education through edupreneurship in promoting the economic independence of vocational high school students in the era of society 5.0. This study uses a descriptive qualitative approach. The research subjects were selected using purposive sampling techniques, with criteria for vocational high schools that have integrated the edupreneurship program into their learning processes. Data collection techniques were carried out through semi-structured interviews, observations, and documentation studies. The analysis process was conducted through data reduction stages, data presentation, and conclusion drawing. The results of the analysis show that vocational education, particularly in vocational high schools (SMK), plays a strategic role in producing a generation that is job-ready while also capable of creating jobs independently. However, various structural and cultural challenges such as competency mismatch, weak technology integration, and low entrepreneurial spirit remain major obstacles in achieving the economic independence of graduates. In the era of Society 5.0, which demands technological proficiency and sustainable innovation, a more adaptive and transformative educational approach is needed. In this context, edupreneurship emerges as a strategic solution to revitalize vocational education to make it more contextual, productive, and highly competitive.

Abstract

This research uses normative research methods with a statute approach, historical approach, and conceptual approach.  This research aims to find out, examine, and analyze the urgency of legal protection for persons with disabilities against authentic deeds made before a Notary and also to examine and determine the validity of notarial deeds made by persons with disabilities through alternative relevant attestation procedures. The result of this research is that the reconstruction model for the validation of an authentic deed made before a notary for a disabled person follows the provisions of Article 44 of the UUJNP, but this provision must be accompanied or accompanied by at least 2 (two) witnesses who will later make a certificate of testimony (Affidavit) before the notary that he witnessed the disabled person had made the deed before the notary concerned. In essence, the reconstruction of authentic deed attestation is needed to realize the purpose of the law it self, in the form of certainty, justice, and expediency.
