Abstract

Syringe needles are among the most commonly used medical tools in healthcare facilities across Indonesia, contributing significantly to medical waste. Improper disposal of syringe waste poses risks of disease transmission and potential misuse. Presently, small-scale beauty clinics resort to third-party waste management services due to the lack of incinerators. This research aims to develop a device capable of melting used syringe needles to ensure safe waste processing for both humans and the environment. Additionally, the objective is to create a low-budget needle destroyer, making it accessible to other healthcare services. The melting method is employed for needle destruction, utilizing a transformer to generate electrical current and heat. This approach offers ease of use and eliminates air, noise, and metal dust pollution. Through experimentation with various syringe sizes (1 cc, 3 cc, 5 cc, and 10 cc), it was found that melting times sequentially increase with needle size: 4 seconds for 1 cc, 5 seconds for 3 cc, 6 seconds for 5 cc, and 8 seconds for 10 cc syringes. This research contributes to sustainable healthcare waste management practices, ensuring safer and more affordable solutions for healthcare facilities

Abstract

Penggunaan biopelet di Indonesia saat ini masih tidak banyak, meskipun sumber daya biopelet di Indonesia, khususnya di pulau Sumatera, sangatlah banyak dari berbagai variasi sumbernya, seperti limbah dari industri perkebunan, pertanian, dan lainnya. Dalam aplikasinya, biopelet yang berasal dari kayu dan non-kayu maupun kombinasi keduanya dalam penentuan proses yang menggunakan Design Expert metode Mixture D-Optimal merupakan sesuatu yang terbarukan. Penelitian ini bertujuan untuk mendapatkan proses yang optimal pada produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu menggunakan Design Expert 13.0, kemudian dilakukan standarisasi proses produksi terhadap produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu. Berdasarkan hasil terhadap respon yang telah ditentukan, yaitu kadar air, kadar abu, dan nilai kalor terhadap biopelet, terdapat biopelet dengan variasi proses yang memenuhi kriteria SNI 8021–2014 Persyaratan Pelet Kayu dan SNI 8675–2018 Persyaratan Pelet Biomassa. Proses optimal terpilih pada produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu berdasarkan Design Expert 13.0 adalah dengan ukuran partikel 40 mesh dan temperatur pengovenan 120°C yang memiliki nilai desirability 0,953.

Abstract

CV. XYZ is a company engaged in food processing, it processes meat as the main raw material. Beef rollade is one of the products produced by CV. XYZ using "Fort Quarter" (FQ) beef as raw materials and auxiliary ingredients, i.e spices, eggs, onions, TVP (Texture Vegetable Protein) Red, and flour. TVP Red is an important auxiliary raw material in beef rollade production. A shortage of auxiliary materials for TVP Red during the production process will disrupt the process and if production continues, the product quality will decrease. Currently, the inventory policy carried out by CV. XYZ is to check the inventory of and auxiliary materials just before carrying out production activities so that if there is a shortage of auxiliary materials, new orders are made at that time. Therefore, the aim of this study is to determine the number of orders and the optimal frequency of ordering TVP Red using the EOQ method and determining the total cost of TVP Red inventory before and after using the EOQ method. Based on the results of calculations carried out using the EOQ, it can be concluded that the number of economical purchases of TVP Red is 1,007.6 Kg per order. With that number of purchases, the frequency of ordering by CV. XYZ is reduced to 13 times in one year. The difference in the frequency of these purchases is 25 times in one year. With purchase frequency of 13 times in one year, it can save the total inventory cost of Rp. 163.972,4.
