Production Parameters of Three Varieties of Red Onion Origin of Botanical Seed Applied With Auxin
Full text linkShallots are one of the horticultural commodities that are highly expected to be cultivated intensively. The need for shallots nationally increases from year to year. These needs cannot be increased by increasing national production. One thing that can be done to make shallots available is to use good varieties and provide growth regulators with auxin using botanical seeds (True Shallot Seed) as a seed source. This study aims to determine the effect of the interaction between varieties with auxin concentration on the growth and production of shallots. This research was carried out in the Exfam Land, Faculty of Agriculture, Hasanuddin University, Makassar, South Sulawesi Province, from August to November 2021. This study used a Split plot design which consisted of two factors, the first factor as the main factor being different plant varieties, namely Lokananta, Maserati, and Sanren. While the sub-plot is the concentration of Auxin consisted of 4 levels, namely 0 mg L-1,100 mg L-1, 200 mg L-1, and 300 mg L-1 . The experimental results showed that the red onion variety using the variety with a concentration of 200 mg L-1 gave the best results on the fresh weight of shallots (123.80 g), the dry weight of shallots (93.77 g), the tuber weight of (86.63 g/plot), tuberproduction (4.51 kg/plot), and productivity (19.50Â ton ha-1). The treatment of shallot varieties using the Sanren variety gave the best results on the parameters of the number of bulbs (1.89 bulbs). The application of auxin at a concentration of 300 mg L-1 gave the best results on the tuber diameter parameter of 28.42 mm
Growth and Production of Organic Tomatoes (Solanum Lycopersium) on the Application of Organic Fertilizer and Mulch Types
Full text linkThis research aimed to analysis the effect of various types of organic fertilizer and mulch types on growth and production of tomato plants. Research was conducted at Liliriaja District, Soppeng Regency, South Sulawesi on January-June 2023. This research used a factorial 2 factor experiment in Randomized Complete Block Design (RCBD) as the environmental design. The first factor is organic fertilizer with 3 types: chicken compost 15 tons ha-1, cow manure 15 tons ha-1, and goat manure 15 tons ha-1. The second factor is mulch with 3 types: without mulch, 10 tons ha-1 rice husk mulch, and plastic mulch. The results showed that there was an interaction between chicken compost fertilizer and rice husk mulch at the number of fruit / plot (260.00 fruits), fruit weight / plot (8.00 kg) and production (26.67 tons ha-1). Chicken compost in 15 ton ha-1 gave the highest number of fruit /plant (18.93 fruits) and fruit weight/plant (727.00 g)
Indonesia Natural Rubber Export Competitiveness Analysis in World Export Market
Full text linkThis study aims to determine the level of export competitiveness of Indonesia’s natural rubber products, namely TSNR (Technically Specified Natural Rubber), natural rubber latex pre-vulcanized or not, Natural rubber smoked sheets, Mixture of natural rubber latex, and compounded of natural gums. In addition, Comparing Indonesia’s natural rubber competitiveness to Malaysia and Thailand in the ASEAN region. The research method used Revealed Comparative Advantage (RCA) and market share using time series data from 2012 to 2021. There are only four types with good competitiveness with RCA > 1, namely TSNR, Smoked Sheets, Mixture Latex, and Compounded Natural Gums. These four commodities have a comparative advantage with RCA > 1. This shows that Indonesia specializes in these commodities in the world market. Natural rubber TSNR has the highest market share at 41%. The lowest is Natural Rubber Latex and Compounded of Natural Gums at 1%. Indonesia's natural rubber has a comparative advantage or stronger competitiveness than Thailand and Malaysia. This is shown by Indonesia's average RCA value for ten years from 2012 to 2021, which is 30.37. However, Indonesia’s market share has been lower than Thailand’s in ten years

Identification of Lines Inducing Male Sterility in Hybrid Maize
Full text linkEfficiency and effectiveness in controlling crossbreeding are pivotal in yielding superior hybrid varieties with desired traits such as genetic purity and high productivity. Cytoplasmic Male Sterile (CMS) is a crucial component in hybrid variety assembly. This study aims to identify the genotypes that can induce male sterile lines based on genetic diversity and the level of pollen sterility in the prospective male sterile genotypes tested, consisting of seventeen genotypes. The research findings revealed that the genetic diversity among the seventeen observed male-sterile candidate genotypes tends to vary in quantitative traits. Among the quantitative traits, JHD14 exhibited indications of being a male sterility inducer compared to the other genotypes observed, demonstrating a value of 0.00 g in terms of pollen weight. This is further substantiated by the microscopic examination of JHD14 pollen grains, which displayed 100% sterility.Â
Chinese Foreign Trade Policy within GATT-WTO: Parallel or Shadow Institutionality?
Full text linkThe discussion of China's rise as a global economic and political power in recent decades has been fueling various theoretical discussions based on the evolution of its foreign trade policy. Hence, empirical research method is proposed in the field of international law involving the study of institutions, norms and procedures based on academic evidence. In this sense, this article analyzes the underlying reasons why this country, despite its late insertion into the Multilateral Trading System, has a relevant influence in the present. In fact, this influence from China has generated a scenario of regionalism both in the Asia-Pacific and with other strategic partners. All this, in addition to also evidencing a progressive "shadow institutionalism". Thus, this whole previous situation means that exist a real primacy achieved by China at world nowadays which also tends, in certain circumstances, to tarnish and even undermine the role of the GATT-WTO paradigm and its logic of multilateralism. Accordingly, this implies a particular scenario that suggest a whole parallel model of authority that affects the dynamics of international relations
A TYPOLOGY TO EXPLAIN FACTORS AFFECTING THE ADOPTION OF AGRI-ENVIRONMENTAL PRACTICES: A CASE STUDY IN JAPAN
Full text linkLike the governments of many other countries, the Japanese government is encouraging transitions to more environmentally sustainable agricultural schemes. However, there have been numerous debates around the world about what kind of farmers are willing to participate in agri-environmental practices, and no clear consensus has yet to emerge. Towards that end, some studies have used quantitative analysis to identify the demographic characteristics that affect the adoption of conservation practices, while others have used qualitative analysis to clarify the cognitive values farmers employ in their daily lives as social beings. In this study, to investigate farmers' motivational heterogeneity from the viewpoints of values and demographic characteristics, quantitative research was conducted in a rural community in the North-eastern region of Japan, where environmentally friendly agricultural practices have been used for more than 15 years. In this survey, 81 rice farmers responded to a variety of questions regarding their intentions to grow environmentally friendly rice and related demographic characteristics. Examining this data using factor analysis revealed that farmers were motivated to continue conservation practices due to three primary factors: stewardship, self-interest, and social networks. Contrary to previous studies, the stewardship factor was correlated with the self-interest factor, that indicates the emergence of a new type of environmentally friendly farmers. Also, as opposed to other studies that emphasized the importance of the stewardship and the self-interest, this study showed by cluster analysis that some farmers continued their practice solely due to the social networks. In addition, this study bridged the gap between previous qualitative and quantitative approach by indicating the relation between farmers value orientation and their demographic characteristics. To further encourage transitions to agri-environmental systems, policies that deal with farmer heterogeneity will need to be implemented. Â

In this case the state civil apparatus either as a financial operator or treasurer in the working area of the Jeneponto District Government agency. Simultaneously the perception of ease of use and usefulness affects the acceptance of RIFS. In this case the operator / user feels that RIFS is easy to use and useful in doing the job
Effects of Career Development and Competencies on Social Affairs: Employee Performance as Mediating Variable
Full text linkThis study aims to know how great the influence of career development, motivation work, and competence on employee performance as well as the impact on the Social Affairs Agency of South Sulawesi Province. Method analysis used is analysis path. The research results show that the development of a career and competence in a way simultaneous is very influential in social assistance services. However, partially, competency does not influence social assistance services, while employee performance partially has a strong relationship with social assistance services. A combination of development career, competency, and performance employee is a strong unity that affects social assistance services. The results of the indirect effect test using Sobel Test calculations have proven that there is a positive and significant indirect effect on career and competency development, through employee performance regarding social assistance services. This indicates that performance employees are capable of mediating completely (full mediation) between career development and competency towards improving social assistance services at the Social Affairs Agency of South Sulawesi Province
