Abstract

Proses distilasi uap minyak serai wangi secara konvensional sering mengalami pemborosan energi dan fluktuasi suhu yang berpotensi menurunkan kualitas produk. Penelitian ini bertujuan mengembangkan sistem kendali otomatis dan pemantauan berbasis Internet of Things (IoT) untuk mengoptimalkan efisiensi energi serta menjaga kualitas produk minyak serai wangi. Sistem mengintegrasikan algoritma Fuzzy Logic dua variabel input independen, yaitu temperatur boiler (Tb) untuk mengendalikan heater dan temperatur kondensor (Tk) untuk mengendalikan pompa pendingin, serta platform IoT untuk pemantauan real-time. Pengujian dilakukan selama 120 menit menggunakan 2 kg serai segar dengan membandingkan kinerja sistem berkendali dan tanpa kendali pada kondisi awal yang setara. Hasil penelitian menunjukkan bahwa penerapan Fuzzy Logic mampu menjaga kestabilan operasional pada temperatur boiler 114℃ dan tekanan 78 kPa. Sistem berkendali berhasil menekan konsumsi energi dari 1,82 kWh menjadi 1,50 kWh, atau menghemat energi sebesar 17,6% (0,32 kWh). Selain itu, penghematan energi tidak mengorbankan kualitas produk, ditunjukkan oleh peningkatan rendemen minyak (0,63% vs 0,54%) dan kadar sitral (35% vs 25%) dibandingkan sistem tanpa kendali. Validasi sensor temperatur dan tekanan menunjukkan deviasi rata-rata masing-masing sebesar 4,04℃ (5,6%) dan 1,28 kPa (2,9%). Penelitian ini membuktikan bahwa integrasi Fuzzy Logic dan IoT efektif meningkatkan efisiensi energi sekaligus mempertahankan mutu hasil distilasi uap serai wangi.

Abstract

Al-Zaytun Islamic Boarding School in Indramayu, West Java, has attracted public attention on social media. The previous Eid prayer went viral because men and women stood in the duplicate prayer rows. In addition, several other aspects also drew public attention, such as the Friday prayer call style being different from the usual, introducing Jewish greetings, and allegedly allowing students to commit adultery, with the sin being redeemable for a certain amount of money. These controversies naturally sparked various reactions from the Indonesian public. This study employs the Support Vector Machine (SVM) method combined with Term Frequency-Inverse Document Frequency (TF-IDF) word weighting to evaluate public sentiment regarding various controversies associated with the Al-Zaytun Islamic boarding school. The data used in this research consists of tweets collected through a scraping process using Tweet Harvest with several relevant keywords. The results are analyzed to classify sentiment into three categories: positive, neutral, and hostile. The entire process is carried out systematically to obtain classification results that are both accurate and relevant to the ongoing social phenomena. Therefore, this study aims to implement the Support Vector Machine (SVM) algorithm to classify Twitter user sentiments towards the Al-Zaytun Islamic Boarding School controversy. The research collected 1,018 tweets through a scraping process using Tweet Harvest via Google Collab, with keywords such as "alzaytun," "zaytun," "panji gumilang," and "al-zaytun." The sentiment distribution consisted of 133 positive sentiments, 313 negative sentiments, and 572 neutral sentiments. Based on the classification evaluation results, the Support Vector Machine algorithm achieved an accuracy of 76%, a precision of 78.3%, a recall of 67.6%, and an F1 score of 69.6%.
