Abstract

Cadangan energi di Indonesia terutama energi fosil (minyak bumi, batubara) semakin menipis. Oleh karena itu diperlukan usaha penghematan dan pengembangan sumber energi arternatif. Salah satu cara yaitu dengan mengkonversi limbah sabut kelapa muda (Cocos nucifera) menjadi bio-fuel. Penelitian ini dilakukan menggunakan metode piro-katalitik pada temperature 600 ⁰C. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh konsentrasi zeolit (3%, 5%, 7%) terhadap kualitas bio-fuel. Uji kualitas BBM meliputi viskositas, densitas, specific gravity, API gravity, nilai kalor dan analisis GC-MS. Hasil penelitian menunjukkan bahwa konsentrasi katalis zeolit berpengaruh pada kualitas bio-fuel. Nilai kalor yang dihasilkan untuk setiap kosentrasi katalis 3%, 5%, 7% berturut-turut adalah 10.412 kkal/kg; 10.421 kkal/kg; dan 10.417 kkal/kg. Analisis komposisi kandungan bahan bakar dalam bio-fuel menggunakan GC-MS diperoleh senyawa acetid acid, phenol, furfural, pyridine, creosol, benzene, ethanol dan aseton dengan persentase bahan bakar mencapai 73,46%, sehingga bio-fuel dari limbah sabut kelapa muda (Cocos nucifera) dapat digunakan sebagai sumber energi.

Abstract

This research proposes an automatic approach to identify eucalyptus species based on leaf images using color histogram feature extraction and the Decision Tree algorithm. Eucalyptus is known as one of the most productive plants in the world with various uses in the timber, biofuel and pharmaceutical industries. However, its wide environmental adaptability and rapid growth pose challenges in identification and management. The proposed approach focuses on the use of Artificial Intelligence (AI) technology and image analysis to solve the identification problem. The color histogram feature extraction method is used to extract visual information about the color distribution of eucalyptus leaves. The Decision Tree algorithm is used to build a classification model based on the extracted features. Model evaluation is carried out using accuracy, precision, recall and F1-score metrics. The results showed that this approach was effective in identifying eucalyptus species, with a high level of accuracy. In addition, the development of this method offers opportunities for further applications in various fields, including forest mapping, mobile applications, and the timber industry. By combining advances in AI and image analysis, this research has the potential to become an important cornerstone of nature conservation and environmental sustainability efforts, and help strengthen natural resource management globally

Abstract

Background : One of the side effects of chemotherapy related to hematology can be neutropenia. Neutropenia can occur in patients receiving chemotherapy with a combination of taxan and platinum regimens, such as Paclitaxel and Carboplatin. Loss of neutrophils can cause disruption of the immune defense mechanism and increase the risk of infection in patients. So it is necessary to prevent infection both pharmacologically and non-pharmacologically. Objective : To describe neutropenia in breast cancer patients undergoing neoadjuvant paclitaxel and carboplatin chemotherapy, as well as actions that can be taken to prevent infection in patients. Case Description : A 35-year-old patient, with a medical diagnosis of positive HER2 ductal mammary gland left and experienced severe neutropenia with a neutrophil count # or ANC (absolute neutrophil count) 0.021 x 103/µL. During treatment, prevention of infection is carried out by giving leucogene, washing hands, applying aseptic techniques, using PPE, and monitoring signs and symptoms of infection. In addition, the cleanliness of the environment around the patient must be maintained and environmental modifications can be made. As well as providing education to patients and families regarding hand washing, nutritional intake, and limiting the number of families. Conclusion : Severe neutropenia in breast cancer patients undergoing chemotherapy can increase the risk of infection. There are several actions that can be taken by patients and their families, health workers, especially nurses, as well as by managing the surrounding environment to prevent infection in patients.
