Abstract

Floating cultivation is an innovative techniques that enables optimal plant growth on flooded land. This system is particularly suitable for shallot plants, which are susceptible to waterlogging, as it can prevent root asphyxiation, improve aeration, and optimize yields in flood-prone areas. This study aimed to examine the effect of chicken manure and ZA fertilizer on the agronomic characteristics, physiological responses, and antioxidant activity of shallots (Allium ascalonicum L.) grown using a floating cultivation system. The research was conducted from July to September 2024 in the Kertapati District, Palembang, South Sumatra. A Factorial Randomized Block Design (FRBD) was used, with two factors : chicken manure (0, 1, 2, and 3 kg/plant) and ZA fertilizer (0, 2.00, 5.00, and 7.00 g/plant). Observed parameters included leaf length, number of leaves, number of tillers, wet stover weight, wind-dried tuber weight, fresh tuber weight, tuber diameter, chlorophyll content, and flavonoid content. The results showed that the application of 2 kg chicken manure and 5.00 g/plant of ZA fertilizer significantly improved leaf length, number of leaves, tiller formation, tuber yield, biomass production, and flavonoid content. Additionally, chicken manure enhanced soil fertility and nutrient uptake, while ZA fertilizer supported chlorophyll synthesis and antioxidant activity. In the floating cultivation system, the combination of these two treatments produced synergistic effects that optimized shallot growth and quality.

Abstract

Compost production in Indonesia is often hampered by conventional methods that rely on manual mixing, resulting in lengthy processing times, high labor requirements, and inconsistent compost quality. This study aimed to develop a mechanical compost mixer system featuring an innovative flow gate in a dual-brick-bin setup. The innovation is designed to improve mixing efficiency, mixture homogeneity, and energy consumption. The research was conducted in Tanjung Tebal Village, Lahat Regency, from March to June 2024, using materials such as household organic waste, animal manure, coffee husks, dry leaves, fresh leaves, and the EM4 bioactivator. The methodology investigated using a comparison of a 9HP gasoline engine and equipped with the innovative flow gate to manual methods. Parameters compared include mixing time, energy consumption, homogeneity distribution, and residual material. The results show the mechanical system reduced mixing time by up to 30% from an average of 45 minutes using manual methods to 30 minutes, mixture homogeneity increased to 95% compared to 70% with manual methods, while residual material decreased from 15% to 6%. The flow gate innovation in the dual-brick-bin system proved effective in enhancing the efficiency of the compost mixing process. Implementation of this technology has the potential to support organic waste management in rural areas, reduce environmental pollution, and promote sustainable agriculture. Further research is recommended to evaluate the system’s efficiency on a larger scale.

Abstract

The agriculture sector in Indonesia contributes 14.5% share of gross domestic product (GDP) in 2012 and the number of farmer accounts for about 40% of total labor force population in Indonesia. However, many of the irrigation systems have seriously been deteriorated. Consequently, DGWR (Director General of Water Resources) cannot operate the irrigation systems properly and the farmers have been facing difficulties in obtaining sufficient irrigation water and rice production. Based on the results of “appraisal mission for Rentang Irrigation Modernization Project between Japan  International Cooperation Agency (JICA) and Government of Indonesia Represented by Ministry of Public Works and Housing and National Development Planning Agency” (August 2016), the Rentang Irrigation Modernization Project (hereinafter called RIMP) was started in August 2020. The RIMP consists of 15 packages for canal upgrading works, one (1) package for TM/TC system works, and one (1) package for Modernization Support Program (hereinafter called MSP). This paper mentions the land consolidation which is one of important and advanced activities in the RIMP, including background of the first introduction in Indonesia, site selection, socialization with benefit farmers, survey including geographical and cadastral and agricultural soil, design of irrigation canals and drains and farm roads, a land reallocation plan, issue of land certifications, improvement of soil, coordination with farmers during construction, introduction of IPHA (Water Efficient Rice Irrigation) and mechanization, and a knowledge movie. The implementation resulted in about a 90% increase in plot size and notable improvement in irrigation efficiency.

Abstract

The low selling price of tea in the country by PTPN 7 Regional 1 Gunung Dempo Pagar Alam is currently causing the selling price of tea plant shoots to be increasingly cheaper as indicated by the decreasing number of farming revenues and the low farming income received by the state-owned company. The aim of this research is to describe the farming performance carried out by PTPN 7. Apart from that, the main aim of this research is to analyze the value of tea farming starting from the value of farming revenues, farming costs and farming income. The research results show that that tea farming is still feasible and profitable to continue to be developed. This is evidenced by the B/C ratio value which exceeds 1, which indicates that each unit cost incurred still generates profit. In addition, the R/C ratio value in all PTPN 7 plantation divisions ranges from, which means that for every IDR 1 of total farming costs incurred, the company earns revenue of Rp 1,24. Thus, tea farming at the research location still makes a positive contribution to the company’s income and has good sustainability prospects.
