Destri, E., Rejo, A., Hanum, L. (2024). Determination of tempeh wastewater management model in plaju ulu with interpretive structural modeling method. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 409–425). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The development of the household-scale tempeh industry in Plaju Ulu, Palembang, produces wastewater that has the potential to disrupt environmental balance if not managed properly. This research aimed to establish appropriate recommendations for a model of wastewater management for tempeh to minimize the impacts caused by waste disposal. This study uses the Interpretive Structural Modeling (ISM) approach to determine the relationships between elements in formulating the model recommendations. The framework variables for this research include three main elements: the background conditions of education, economy, and socio-cultural aspects of tempeh producers. The research findings indicate that the implementation of wastewater management for tempeh in Plaju Ulu needs to be supported by strengthening formal education through workshops or seminars for tempeh producers on effective waste management techniques, or by collaborating with academics to develop innovative waste processing technologies. The success of waste management also relies on the welfare of tempeh producers, necessitating efforts such as product diversification from wastewater raw materials and providing access to product certification to enhance competitiveness and sales. Additionally, the management of tempeh liquid waste requires the development of local regulations governing the disposal and management of wastewater, involving tempeh associations in discussions to ensure that the management stages are accepted and implemented effectively. A model for managing tempeh wastewater that focuses on education, economy, and socio-cultural aspects is expected to create a sustainable environmental system through good collaboration among all partiesn.

Abstract

Continuous modifications of Layered Double Hydroxides (LDH) materials are essential to enhance their structural stability and improve their capacity for pollutant adsorption, addressing the need for more effective remediation strategies in environmental applications. This research study has proposed the preparation of CuAl-LDH supported filamentous macroalgae of Spirogyra sp. (CuAl-LDH/SA) via coprecipitation and hydrothermal methods. The prepared CuAl-LDH/SA composites were investigated for the adsorption of direct yellow 12 (DY) and remazol red (RR) dyes in batch mode experiments. The structure and morphology of the prepared CuAl-LDH/SA were identified by X-ray Diffraction (XRD), Fourier Transform Infra Red (FT-IR), (Brunauer-Emmett-Teller) BET surface area, Thermogravimetry / Differential Thermal Analyzer (TG/DTA), and Scanning Electron Microscope (SEM). For the adsorption process, the effects of initial pH, contact time, initial concentration, temperature, adsorption selectivity, and adsorbent regeneration, as well as kinetics, isotherms, and thermodynamics were studied. The adsorption selectivity test resulted in the RR dye being more selective compared to DY. The maximum capacities for RR adsorption were 72.464 mg/g (pH = 2, 150 min, 303 K). CuAl-LDH/SA can be regenerated for 4 cycles with a percent removal of 29.32%. The adsorption process followed the intraparticle diffusion kinetics model and Langmuir isotherm. Thermodynamic studies showed that the adsorption of RR using CuAl-LDH/SA was endothermic and spontaneous. The results of this study indicate that CuAl-LDH/SA composite material shows potential material in the removal of anionic dyes from aqueous solutions.

Abstract

Indonesia is one of the countries affected by the COVID-19 pandemic. In the era of the COVID-19 pandemic, Tuberculosis disease is no longer in focus because the COVID-19 pandemic is the focus of the main problem. TB is one of the diseases that causes death in the world caused by bacterial infection Mycobacterium tuberculosis. TB in the pandemic era is very difficult to diagnose because the diagnosis of respiratory disease is directed at COVID-19 disease. Based on this, this study was conducted with the aim of knowing the impact of the COVID-19 pandemic on the findings of TB cases. The study was conducted using a cross-sectional observational analytic method at the Dukuh Kupang Community Health Center, Surabaya. The results showed a decrease in the number of pulmonary TB cases in recent years. This decrease is due to a decrease in screening and diagnosis of suspected TB, as well as an increase in better understanding in the community regarding the difference in symptoms of COVID-19 and TB and a decrease in the examination of TB sputum samples.
