Abstract

ABSTRACT Training on processing coffee leaf waste into herbal tea in Lebah Sempaga Village, Narmada, West Lombok Regency, aims to support tourism activities and improve the skills and knowledge of the community in managing abundant coffee leaf waste. So far, coffee leaf waste tends to be wasted, even though the potential for processing it into herbal tea has high economic value and is beneficial for health. This training includes various stages, starting from the collection of coffee leaves, sorting the separation of the stem from the leaves, washing in running water, drying process, roasting process, reducing coffee leaves (crushing), packaging herbal tea making into products. It is hoped that the results of this training can not only increase community income but also contribute to environmentally friendly waste management. In addition, this training emphasizes the importance of environmental sustainability and community awareness of the potential of natural resources around them.

Abstract

Lebah Sempage Village is rich in crops, especially from plantations, agriculture, livestock, and natural beauty. One of the products produced is oyster mushroom chips, which has been cultivated since 2016 by the Women Farmers Group (KWT) by utilizing sawdust waste. However, the number of oyster mushroom processors is decreasing because many choose to sell them directly to collectors. To overcome this, an innovative participatory based training was held with the aim of motivating the community to be more creative in processing crops, especially oyster mushrooms. This training succeseded in changing mindsets, improving skills, and encouraging community independence in managing oyster mushroom products.

Abstract

This study evaluated the performance of the BLUD Drinking Water Treatment Plant (WTP) in Cimahi to identify parameters exceeding national standards and assess design and operational adequacy. Raw water quality did not comply with PP No. 22/2021 for BOD (11.9 mg/L), COD (24.1 mg/L), detergent (0.426 mg/L), fecal coliform (4.27 × 10⁷ MPN/100 mL), total coliform (1.14 × 10⁶ MPN/100 mL), nitrite (0.093 mg/L), sulfate (0.328 mg/L), TSS (88 mg/L), and zinc (0.061 mg/L). Treated water failed Permenkes No. 2/2023 for color (22.5 TCU) and residual chlorine (0.16 mg/L), while negative removals were observed for fluoride, manganese, nitrite, TDS, and color. Evaluation revealed several design flaws: bar screen spacing of 25 mm and thickness of 10 mm (required 4–8 mm and 25–50 mm); coagulation with constant PAC dosing (18 mg/L) without jar testing; flocculation detention time of 22 min with constant velocity gradients (30.5 s⁻¹) instead of 30–45 min with decreasing gradients; sedimentation with detention time of 0.97 h and surface loading of 3.75 m³/m²·h (required 1.5–3 h and 3.8–7.5 m³/m²·h); filtration with backwash velocity of 41.86 m/h and duration of 5 min (required 46–50 m/h and 10–15 min); and disinfection with velocity gradient of 111 s⁻¹ (required ~500 s⁻¹). Revised designs included reducing bar spacing to 8 mm and thickness to 50 mm, implementing routine jar testing, extending flocculation detention to 30.1 min with step-down gradients (34–26 s⁻¹), deepening sedimentation basins to 6 m (detention 1.54 h, surface loading 3.87 m³/m²·h), increasing backwash velocity to 46.56 m/h for 10 min, and installing a static mixer (G = 1427 s⁻¹) for chlorine application. These improvements are expected to enhance removal efficiency, eliminate negative removals, and ensure compliance with Indonesian drinking water standards.
