      Abstract
      Rayap kayu kering (Cryptotermes sp.) merupakan hama yang menyebabkan kerusakan pada bangunan serta berlignoselulosa. Pengendalian rayap umumnya menggunakan bahan kimia yang berisiko terhadap lingkungan dan kesehatan manusia. Oleh karena itu, diperlukan alternatif pengendalian yang lebih ramah lingkungan. Penelitian ini bertujuan untuk menguji potensi cendawan Dark Septate Endophytes (DSE), yaitu Cladophialophora nyingchiensis S51 dan Cladosporium sp. KSP1, sebagai agen pengendali hayati. Pengujian dilakukan menggunakan metode kontak dan metode umpan dengan tiga taraf konsentrasi suspensi, yaitu 1×105, 1×106, dan 1×107 konidia/ml, serta kontrol. Hasil penelitian menunjukkan bahwa kedua cendawan mampu meningkatkan mortalitas rayap dibandingkan dengan kontrol. Cladosporium sp. KSP1 menghasilkan mortalitas rayap tertinggi dengan nilai LT50 lebih kecil dibandingkan dengan C. nyingchiensis S51. Mortalitas rayap metode kontak dengan C. nyingchiensis S51 38-46%, sedangkan Cladosporium sp. KSP1 54-84%. Mortalitas rayap dalam metode umpan C. nyingchiensis S51 80-94%, sedangkan Cladosporium sp. KSP1 96-100%. Hasil penelitian ini menunjukkan bahwa cendawan DSE berpotensi untuk dikembangkan sebagai agen pengendali hayati rayap kayu kering
       
      Drywood termites (Cryptotermes sp.) are pests that often cause damage to buildings and wood-based materials. Termite control is generally carried out using chemicals, which pose risks to the environment and human health. Therefore, more environmentally friendly control alternatives are needed. This study aims to analyze the potential of Dark Septate Endophytes (DSE) fungi, namely Cladophialophora nyingchiensis S51 and Cladosporium sp. KSP1, as biological control agents. Tests were conducted using contact and bait methods with three levels of suspension concentrations, namely 1×105, 1×106, and 1×107 conidia/ml, as well as a control. The results showed that both fungi were able to increase termite mortality compared to the control. Cladosporium sp. KSP1 showed the highest mortality and the lowest LT50 value compared to C. nyingchiensis S51. Mortality of termites using the contact method C. nyingchiensis S51 is 38-46%, Cladosporium sp. KSP1 is 54-84%. Mortality of termites using the bait method C. nyingchiensis S51 is 80-94%, Cladosporium sp. KSP1 is 96-100%. The results of this study indicate that DSE fungus has the potential to be developed as a biological control agent for drywood termites.
