Tapping was done 3 times a week. The variables observed were latex production (gram/tree/day), dry rubber content (%), latex ash content (%), and latex dirt content (%). Vicar giving 10 SL in the tapping site with a dose of 2 ml / tree gave the highest yield of latex production (93.38 grams / tree / day) and dry rubber content (75.50%) and was significantly different compared to the other treatments. Vicar giving 10 SL in tapping site had no significant effect on latex dirt content and latex ash contentKeywords: Latex, stimulant, product and quality Abstrak Peningkatan produksi lateks pada tanaman karet dapat ditingkatkan dengan menggunakan stimulan. Salah satu pemakaian yang digunakan adalah Vikar 10 SL. Tujuan penelitian ini adalah untuk megetahui penggunaan stimulan pada bidang sadap dalam mempengaruhi produksi dan kualitas lateks. Penelitian ini dilakukan di Desa kasang Parit Kecamatan Sekernan Kabupaten Muaro Jambi, dan Balai Pengujian dan Sertifikasi Mutu Barang (BPSMB) Disperindag Propinsi Jambi. Penelitian dilakukan pada bulan Juli sampai dengan Agustus 2017. Rancangan yang digunakan adalah Rancangan Acak Lengkap dengan satu faktor perlakuan pemberian stimulan (Vikar 10 SL) dengan empat taraf perlakuan  yaitu; Tanpa perlakuan (V0/kontrol),  1 ml/ Pohon (V1),  2 ml/pohon (V2), 3 ml/pohon  (V3). Setiap perlakuan diulang sebanyak 4 kali. Dengan menggunakan jari dioleskan larutan Vikar 10 SL pada alur sadap  yang disesuaikan dengan perlakuan, dan didiamkan selama 24 jam. Penyadapan dilakukan pada pagi hari esoknya, dengan mengikuti alur torehan dan ditampung dalam cawan dan dibiarkan sampai lateks berhenti menetes. Pemberian Vikar dilakukan sekali 7 hari selama 30 hari. Penyadapan dilakukan  3 kali dalam seminggu. Peubah yang diamati adalah produksi lateks (gram/pohon/hari)), kadar karet kering (%), kadar abu lateks (%), kadar kotoran lateks (%).
