Abstract

Partikulat yang dikeluarkan oleh asap rokok diketahui berkontribusi terhadap polusi udara dan berdampak negatif terhadap kesehatan manusia. Oleh karena itu, diperlukan upaya untuk mengurangi konsentrasi asap rokok di udara. Dalam penelitian ini, kami mengembangkan filter partikulat yang terbuat dari serbuk kayu dengan tepung terigu sebagai perekat filternya. Variasi filter yang digunakan pada penelitian ini adalah filter yang dijemur langsung di bawah sinar matahari dan menggunakan pengering rambut. Filter ini ditandai dengan nilai efisiensinya dalam mengurangi emisi asap rokok. Efisiensi filter dalam mereduksi partikel ditentukan dengan membandingkan asap rokok sebelum dan sesudah penambahan filter. Hasil penelitian menunjukkan nilai efisiensi filter dalam mereduksi partikel asap rokok adalah sekitar 95,24%. Nilai efisiensi yang dihasilkan dari variasi perlakuan filter yang berbeda tidak menunjukkan perbedaan nilai yang signifikan.

Abstract

Household waste management is an important aspect of tourism development in Dara Kunci Village, Sambelia District, East Lombok Regency. Although the tourism potential of Dara Kunci Village holds great promise for boosting the local economy, its development is still in its early stages and requires careful preparation. One aspect that needs attention is waste management, which is a crucial factor in maintaining the beauty and cleanliness of tourist environments. Therefore, this activity aims to raise awareness among the community about the importance of waste management, and to introduce and implement a simple yet effective innovation, namely the use of recycled tin can composters, as an initial step in reducing household waste generation. The methods employed involve community awareness campaigns to promote environmental consciousness, training sessions on compost production using recycled tin can composters as a solution for household waste management systems, and providing guidance on compost production at home as a sustainable solution to reduce household waste generation. The results of this activity demonstrate an increase in knowledge and skills among the residents of Dara Kunci Village in managing household waste, resulting in the production of liquid organic fertilizer and compost. Although not all composts meet the desired maturity criteria, this activity provides valuable insights for the community into the composting process and the importance of patience in achieving optimal results

Abstract

Biomaterial implants are one of the alternatives to replace damaged organs in the body system temporarily (scaffolding) or permanently. Bone biomaterial implants can be obtained through the manufacture of HA/Cs/Coll (HA/Cs/Coll) biocompositeses with the addition of Hydroxypropyl Methylcellulose (HPMC) matrix. The objective is to evaluate how variations in material composition and lyophilization time affect the physical properties of the biocomposites, including density, compressive strength, Young’s modulus, and surface morphology. The manufacture of  biocomposites uses the mechanical thermal method for mixing materials and the freeze drying method for the biocomposites drying process. Composition ratios of HA:Cs/Coll were varied at 3:7, 5:5, and 7:3, while lyophilization durations were set at 24, 48, and 72 hours. Characterizations were performed through density measurements, mechanical testing using a Tensilon machine, and surface morphology analysis using a digital microscope. The results showed that the comparison of biocomposites with a ratio of 7:3 had the highest density of 0.150 gr/cm³, compressive strength of 0.046 MPa, and young modulus of 0.3 MPa. Meanwhile, the biocomposites that was lyophilized for 48 hours showed the best balance between a density of 0.145 gr/cm³, a compressive strength of 0.08 MPa, and a young modulus of 0.17 MPa. Morphological analysis revealed improved porosity and surface uniformity with longer freeze-drying times. Based on this, the resulting HA/Cs/Coll biocompositese has potential as an implant material but further research is needed to improve its mechanical properties by increasing the concentration of the binder, namely HPMC.
