Abstract

Pembersihan sarang burung walet merupakan tahap penting untuk meningkatkan kualitas produk, namun metode konvensional berisiko merusak struktur sarang dan memerlukan waktu relatif lama. Penelitian ini bertujuan merancang dan mengevaluasi sistem pembersih sarang walet berbasis getaran, teknik bubbling, serta kombinasi getaran–bubbling. Kinerja pembersihan dievaluasi menggunakan perubahan massa basah dan waktu pelepasan kotoran pada tiga level operasi (low, mid, high) dan variasi posisi sampel. Parameter evaluasi meliputi selisih massa basah (ΔW), efektivitas pembersihan (E), dan laju pelepasan kotoran (removal rate, R). Hasil menunjukkan bahwa metode kombinasi memberikan performa tertinggi dengan nilai rata-rata E sebesar 4,31%, R sebesar 0,00425 g/s, dan waktu rata-rata t sebesar 53,42 s. Kondisi terbaik diperoleh pada posisi tengah level high dengan ΔW sebesar 0,40 g, E sebesar 8,0%, R sebesar 0,00899 g/s, serta waktu pelepasan kotoran tercepat t sebesar 44,5 s. Metode bubbling menunjukkan kinerja menengah dengan E rata-rata 2,80% dan R rata-rata 0,00222 g/s, sedangkan metode getaran memberikan kinerja terendah dengan E rata-rata 2,51% dan R rata-rata 0,00159 g/s dipengaruhi distribusi getaran yang tidak merata. Validasi instrumen menunjukkan sensor thermocouple memiliki rata-rata error 1,41% (akurasi 98,59%), sedangkan sensor piezoelektrik menunjukkan respons optimal pada frekuensi 500–700 Hz dengan tegangan maksimum 2,4 Vpp. Berdasarkan pengamatan visual, tidak ditemukan kerusakan struktural pada sarang walet pada rentang parameter pengujian.

Swallow nest cleaning is a crucial step to improve product quality. However, conventional cleaning methods may damage the nest structure and often require longer processing time. This study aimed to design and evaluate a swallow nest cleaning system using vibration, bubbling, and a combined vibration–bubbling method. Cleaning performance was assessed based on wet mass reduction and the time required for dirt to detach under three operating levels (low, mid, high) asnd different sample positions. The evaluation parameters included wet mass difference (ΔW), cleaning effectiveness (E), and dirt removal rate (R). The results showed that the combined method delivered the best overall performance, with an average E of 4.31%, an average R of 0.00425 g/s, and an average detachment time (t) of 53.42 s. The best condition was achieved at the middle position under the high level, yielding ΔW of 0.40 g, E of 8.0%, R of 0.00899 g/s, and the fastest dirt detachment time of 44.5 s. The bubbling method demonstrated moderate performance (average E of 2.80% and average R of 0.00222 g/s), while the vibration method showed the lowest performance (average E of 2.51% and average R of 0.00159 g/s), which was influenced by uneven vibration distribution. Instrument validation indicated that the thermocouple had a mean error of 1.41% (accuracy 98.59%), and the piezoelectric sensor exhibited an optimal response at 500–700 Hz with a maximum output of 2.4 Vpp. Visual inspection confirmed no structural damage to the swallow nests within the tested parameter range.
