Abstract

Organic waste management is one of the environmental challenges that requires practical and environmentally friendly solutions. This study aims to design and create organic waste management tools in the form of a composter and Takakura using experimental methods. The composter is designed to support the aerobic composting process with air ventilation, while the Takakura is equipped with coconut fiber pads and cardboard protectors to maintain humidity and air circulation. The manufacturing process is carried out using simple materials and easily accessible equipment, making both tools practical for application on a household scale. The test results show that both tools are effective in processing organic waste into nutrient-rich, environmentally friendly compost that has the potential to support sustainable agriculture. This study concludes that the use of composters and Takakura can be an effective solution to reduce the volume of organic waste that ends up in landfills (TPA), while increasing public awareness of the importance of sustainable waste management. This tool is expected to encourage better waste management and contribute to the creation of a clean and healthy environment.

Abstract

This practicum aims to test the quality of rainwater in storage tanks that are used as clean water. The method used is a descriptive method to analyze three rainwater samples, taken from three different times, namely morning, afternoon and evening. The parameters measured are the degree of acidity (pH), total dissolved particles (TDS), salt content/salinity and electrical conductivity (DHL). The results of this research found that rainwater samples met water quality standards. Rainwater samples have an average pH value of 7.2 and an average salinity value of 3.6, however the TDS and DHL values in the water samples have a constant value of 0. The quality ofrainwater in the storage tank is of good quality to be used as clean water

Abstract

Penelitian ini bertujuan untuk membuat filter air sederhana dan menguji kualitas fisik dan kimia air yang di filter. Metode penelitian yang digunakan adalah metode deskriptif untuk menganalisis sampel air dan metode eksperimen untuk membuat filter air sederhana. Parameter yang diukur adalah derajat keasaman (pH), total partikel terlarut (TDS), kadar garam/salinitas, daya hantar listrik (DHL), turdibity/kekeruhan dan total padatan tersuspensi (TSS). Berdasarkan hasil pengujian menggunakan bahan dan alat diatas terjadi perubahan pada air yang di filtrasi pada satu kali penyaringan. Partikel dari air kotor disaring dengan lapisan kerikil kecil diawal untuk menyaring kotoran kasar lalu diikuti dengan penyaringan kotoran halus dengan pasir. Setelah pasir terdapat lapisan sabut kelapa yang berfungsi sebagai penyaring kotoran halus lalu di beri lagi lapisan pasir lagi, kemudian lapisan sabut kelapa yang juga sama-sama untuk menyaring kotoran halus. Lalu berikutnya terdapat lapisan tawas yang berfungsi untuk mengendapkan partikel. Hasil pengujian air menunjukkan bahwa sampel air yang di filter memiliki nilai pH 4,7, nilai salinitas 5,51 ppm, nilai TDS 7,31 mg/L, nilai konduktivitas 11,10 μS/cm, nilai turdibity 28,1 NTU dan nilai TSS 933 mg/L.
