Abstract

Industri batik saat ini mengalami pertumbuhan pesat, namun dibalik hal tersebut limbah cair yang dihasilkan semakin banyak terutama akibat pewarnaan. Salah satu pewarna yang dipakai yaitu pewarna organik yang berasal dari campuran pewarna alami dan zat pengikat. Pencampuran mengakibatkan zat pewarna bersifat stabil dan sulit mengendap secara alami. Koagulasi - flokulasi secara mekanis dapat menjadi solusi. Penelitian ini bertujuan untuk mengetahui waktu pengadukan terbaik, desain impeller yang efisien, dan kecepatan putaran impeller yang optimal pada koagulasi – flokulasi untuk menurunkan kandungan limbah cair batik organik. Penelitian dilakukan pada skala batch dengan memvariasikan waktu pengadukan, jenis impeller, dan kecepatan putaran impeller koagulasi – flokulasi. Dari hasil penelitian didapatkan waktu pengadukan terbaik yaitu 21 menit, jenis impeller yang efisien yaitu flat paddle 2 blades angle 30 bertingkat dan kecepatan putaran impeller yang optimal yaitu 100 rpm – 50 rpm. Pada variasi terbaik, efisiensi TSS, COD, warna dan kekeruhan masing-masing sebesar 95,62%, 80,44%, 82,42%, dan 84,38%.

Abstract

The growth of the water tourism sector in Malang Regency has resulted in an increase in the generation of Hazardous and Toxic Materials (B3) waste, which threatens the sustainability of aquatic ecosystems. This study presents a representative design for a Temporary Storage Facility (TPS) for B3 Waste that complies with environmental safety technical standards. The study methods used include waste characteristic identification, direct weighing sampling, and engineering design based on the compatibility principle. The evaluation results indicate a total B3 waste generation of 23.35 kg/month, with the largest contribution coming from used battery waste (A102d) of 8 kg/month. Based on this data, a TPS facility with dimensions of 7.5 m x 3.5 m x 3.5 m was designed, equipped with a natural ventilation system, emergency drainage channels, and a spill pallet. The planning of this facility serves as a prototype for mitigating environmental pollution risks to ensure regulatory compliance in water tourism areas.

Abstract

Increasing greenhouse gas (GHG) emissions from industrial activities have become a serious environmental concern, making carbon sequestration through vegetation an important mitigation strategy, particularly in industrial areas where green open spaces serve as natural carbon sinks. This applied study analyzed the influence of biodiversity on GHG emission reduction through vegetation carbon stock estimation across four strata, namely trees, poles, saplings, and undergrowth, in the Mill area (estimated 10 Ha) and Conservation area (3.52 Ha), using an allometric approach from literature converted into tCO₂e, with statistical analysis conducted using the Spearman correlation test and Kruskal-Wallis test due to non-normal data distribution and small sample size. The highest carbon sequestration was recorded in the tree strata at 147.996 tCO₂e (90.7% of total), while the lowest was recorded in the undergrowth strata at 2.190 tCO₂e in the Mill area, with total sequestration of 163.032 tCO₂e in the Mill area and 20,233 tCO₂e in the Conservation area. The results of this applied study concluded that vegetation effectiveness in reducing GHG emissions is more determined by biomass accumulation rather than species diversity, as evidenced by the dominance of a single species (trembesi) contributing significantly to carbon stocks. Greening strategies should prioritize planting high-biomass vegetation such as trembesi (Samanea saman), mahogany (Swietenia mahagoni), and acacia (Acacia mangium), and be integrated with other emission reduction efforts such as energy efficiency and carbon capture technology.

Abstract

Domestic waste management in the industrial sector requires an effective system, one of which begins with waste sorting at source. This applied study aims to evaluate the compliance of the waste sorting program in the paper industry with existing regulations. The method used is descriptive qualitative through field observations, waste inventory data and literature studies, and refers to applicable regulations. The study results indicate that the waste generated consists of organic, inorganic, and residual waste that has been sorted and managed according to its characteristics. Waste utilization is carried out through processing in the RDF (Refuse Derived Fuel) boiler, maggot feed, and internal and external recycling. This program contributes to increasing management efficiency and reducing waste to the Final Processing Site. Optimization is still needed through increasing consistency of sorting and participation of all parties to support sustainable waste management.
