Proses perpindahan koloni semut predator O. smaragdina menggunakan media tali merupakan salah satu upaya konservasi musuh alami pada areal tanaman buah. Penelitian ini bertujuan mengetahui efek jenis dan panjang tali, serta hubungan jenis dan panjang tali sebagai media penghubung antar pohon terhadap aktivitas semut predator. Penelitian dilakukan pada kondisi semi lapang yang terdiri dari 3 unit percobaan yakni tali rafia dan tali tambang, dengan masing-masing panjang 1, 3, dan 5 meter. Setiap unit percobaan di ulang sebanyak 4 kali. Pengujian lapang dilakukan dengan memindahkan koloni melalui media tali dari pohon yang terdapat sarang semut ke pohon yang tidak ditemukan semut predator. Aktivitas semut diukur berdasarkan ada dan tidaknya aktivitas semut pada media tali pada area yang ditentukan. Serta, pada pengujian lapang diamati pula jumlah koloni yang berpindah ke pohon lainnya. Analisis perbandingan menggunakan Uji Wilcoxon dan Analisis Kontigensi, sedangkan analisis hubungan menggunakan Analisis PCA dan Regresi Logisctic Ordinal. Hasil penelitian menunjukkan jenis tali tidak berpengaruh pada kondisi semi lapang, namun hubungan jenis tali tambang dengan predator lebih erat dibandingkan dengan tali rafia. Pada pengujian lapang menunjukkan panjang dan jenis tali mempengaruhi aktivitas semut predator. Terdapat kecenderungan semakin panjang tali meningkatkan aktivitas semut predator. Jumlah sarang yang terbentuk pada pohon tujuan perpindahan mencapai 7 sarang dari 4 pohon dengan komposisi 352 telur, 16 larva, 904 kasta non reproduktif, dan 1 ratu (kasta reproduktif). Faktor suhu, kelembapan, dan kejadian hujan juga cenderung mempengaruhi aktivitas semut predator O. smaragdina.

The movement proces of the colony of weaver ants Oecophylla smaragdina using rope media is one of the convervation efforts of natural enemies in the area of fruit plants. This study aimed to find out the effect of type and length of the rope and also the relationship between type and length of the rope as the inter-tree connecting rope media on the activity of weaver ants. This study was conducted in the semi-field condiotion, consisting of 3 experimental units, using raffia and rope with length of 1, 3, and 5 meters. Each experimental unit was repeated for 4 times. The field testing was carried out by moving the colony through rope media from one tree with ant nets to another tree, where the predatory ants were not found. The activity of weaver ants was measured based on the presence and absence of ants' activity on the rope media in determined area. And also, the field testing was observed to determine the number of ant colony that moved to other tress. The comparative analysis used Wilcoxon Test and Contingency Analysis; meanwhile the relationship analysis used principle component analysis and ordinal logistic redgression. The results of the study showed that the type of rope had no efeect on the semi-field condition; but the relationship between rope type and predator was closer than raffia. The field testing showed tha the length and the type of rope affected on he activity of weaver ants. There was a tendency that longer rope could increase the activity of weaver ants. The number of formed nets on the determined tree reached 7 nests from 4 trees with 352 eggs composition, 16 larvae, 904 non-reproductive castes, and I reproductive caste. The factors of temperature, humidity, and rain also tend to affect the activity of weaver ants Oecophylla smaragdina. Keywrords: Oecophylla smaragdina, Predatory, Ants, Rope
