Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea.

Kerusakan kayu yang disebabkan oleh jamur merupakan masalah serius karena menurunkan kualitas kayu. Pengawetan kayu menggunakan bahan kimia sintetis selama ini menimbulkan dampak terhadap lingkungan.  Penelitian ini bertujuan untuk mengevaluasi sifat antijamur asap cair dari kayu akasia (Acacia crassicarpa) dan kayu jelutung (Dyera costulata) dalam menghambat pertumbuhan jamur S. commune yang dilaksanakan secara vitro. Asap cair dari kayu akasia diperoleh dari pembakaran secara konvensional tanpa pengontrolan suhu, sementara asap cair dari kayu jelutung diproduksi melalui proses pirolisis pada suhu 400°C. Penelitian ini terdiri dari dua set percobaan berdasarkan jenis asap cair yang digunakan. Setiap percobaan disusun menggunakan rancangan acak lengkap yang terdiri dari lima perlakuan, yaitu perlakuan kontrol (0%, tanpa asap cair), dan empat konsentrasi asap cair dengan konsentrasi 1,0; 2,0; 3,0 dan 4,0 %, v/v. Percobaan dilaksanakan dengan metode pengujian makanan beracun secara in vitro menggunakan media potato dextrose agar (PDA) sebagai media pertumbuhan jamur S. commune. Hasil penelitian menunjukkan bahwa asap cair dari kayu akasia tidak mampu menghambat pertumbuhan jamur sampai konsentrasi tertinggi, sementara asap cair dari kayu jelutung memiliki aktivitas antijamur dan telah mempu menghambat pertumbuhan jamur S. commune secara maksimal (100%) pada konsentrasi 2%.
