Salah satu masalah dalam budidaya bibit Falcataria mollucana di persemaian adalah serangan hama Pseudococcus calceolariae. Serangan hama tersebut menghambat pertumbuhan bibit dan pada akhirnya menyebabkan kematian bibit. Beberapa tanaman yang ditemukan di lapangan, seperti Swietenia macrophylla, Azadirachta indica, Morinda citrifolia, dan Carica papaya, memiliki senyawa bioaktif yang dapat digunakan sebagai pestisida botani. Tujuan dari penelitian ini adalah untuk mengetahui jenis ekstrak daun yang efektif dalam mengendalikan hama P. calceolariae pada bibit F. mollucana berdasarkan penurunan insiden dan keparahan serangan P. calceolariae. Hasil penelitian menunjukkan bahwa ekstrak daun S. macrophylla, A. indica, M. citrifolia, dan C. papaya efektif dalam mengendalikan hama P. calceolariae pada bibit F. mollucana. Ekstrak daun A. indica memberikan penurunan insiden dan keparahan serangan P. calceolariae yang lebih tinggi dibandingkan dengan ekstrak daun lainnya, yaitu sebesar 80,13% dan 57,69%.

The Wood Museum in the city of Sampit was built as a place to store historical objects to commemorate the glory of East Kotawaringin Regency in the wood industry. The existence of this wooden museum is very important considering that the museum does not only have a function as a protector of cultural heritage objects, but also as a place for forming ideology, discipline and developing knowledge for the public. This study aims to determine the potential and perceptions of visitors to the wood museum. The research method is in the form of observation and structured interviews using a questionnaire, then the data is analyzed by referring to the Museum Standard Guidelines (Ministry of Education and Culture, 2020) and SNI 9042:2021. The results of the study showed a) The potential for the Wood Museum in the city of Sampit was classified as Adequate (value 2.22). This potential is supported by accessibility and supporting facilities with a Sufficient value (2.95). b) The people of Sampit City are very aware of the existence of the Wood Museum, but several program activities have not been implemented causing a lack of community visits to the Wood Museum

Meranti (Shorea spp) is a commercial trees that dominates the lowland tropical rainforests of Indonesia. Harvesting of this species has been carried out since the early 70's until now, but efforts to cultivate meranti are still very few. The silvicultural system of TPTJ with silin technique has placed meranti as species that must be planted by companies of forest concession. This study aims to construct a polynomial growth model for meranti at PT Sari Bumi Kusuma, so as to be able to predict the achievement of diameter, branch-free height and total height of meranti plants at a certain time. Meranti plants at PT Sari Bumi Kusuma have a diameter growth model: Y= 0.6076 + 0.3067X + 0.0524X2 (R2 : 94.74%), a branch-free height growth model: Y=0.0315+0.4787X+ 0.0081X2 (R2 : 89.53 %) and total height growth model: Y=0.4957+0.758X+0.0138X2 (R2 : 93.78%). The TPTJ system has a cutting cycle of 25 years with a limited diameter of harvested trees is 40 cm. Based on the results of this modeling, most of these trees have reached a diameter of 41.03 cm; branch-free height of 17.06 m and a total height of 28.07 m, so that it is ready to be harvested at the age of 25 years
莫兰蒂(Shorea spp)是一种商业树木，在印度尼西亚的低地热带雨林中占主导地位。从上世纪70年代初至今，人们已经开始采收这种品种，但培育莫兰蒂的努力仍然很少。采用硅林技术的TPTJ造林系统将莫兰蒂列为必须由森林特许权公司种植的物种。本研究旨在构建PT Sari Bumi Kusuma莫兰蒂的多项式生长模型，以预测某一时刻莫兰蒂植株的直径、无枝高度和总高度的实现情况。山林莫兰蒂植物的直径生长模型为Y= 0.6076 + 0.3067X + 0.0524X2 (R2: 94.74%)，无枝高度生长模型为Y=0.0315+0.4787X+ 0.0081X2 (R2: 89.53%)，总高度生长模型为Y=0.4957+ 0.7588 x +0.0138X2 (R2: 93.78%)。TPTJ系统的采伐周期为25年，采伐树木的有限直径为40厘米。根据建模结果，这些树木的直径大多达到41.03 cm;无枝高17.06米，总高28.07米，25岁即可采收

Kelompok usaha sosial hutan desa yang mengembangkan budidaya lebah tak bersengat adalah kelompok yang memanfaatkan lebah tak bersengat untuk budidaya dan telah memiliki produk, yaitu madu. Masyarakat yang mengelola lahan hutan sosial ini adalah Desa Tuwung, Kabupaten Pulang Pisau, Provinsi Kalimantan Tengah. Penelitian ini bertujuan untuk menentukan potensi dan nilai ekonomi, serta faktor-faktor yang memengaruhi produktivitas madu lebah tak bersengat. Metode penelitian yang digunakan adalah metode deskriptif kualitatif. Usaha budidaya lebah tak bersengat di Desa Tuwung menghasilkan 40 liter madu dari 33 sarang lebah, dimana potensi budidaya lebah tak bersengat masih belum optimal. Nilai ekonomi, yaitu pendapatan dari penjualan madu dalam satu tahun, mencapai Rp 10.000.000. Produksi madu selama satu tahun mencapai 40 liter dengan harga jual Rp 250.000 per liter, sehingga pendapatan kelompok usaha ini masih belum optimal atau relatif rendah.

Phantera tigris sumatrae memiliki daya adaptasi yang cukup tinggi terhadap perubahan habitat di luar habitat aslinya, adapun perubahan kawasan yang berubah fungsi yang dulunya kawasan hutan menjadi kebun masyarakat, yang menyebabkan harimau sumatera keluar dan masuk ke pemukiman masyarakat untuk mencari sumber pangan akibat pergeseran kawasan hutan. Harimau sumatera masih dapat ditemukan di pulau sumatera, Kurangnya pengetahuan masyarakat tentang aktivitas harimau sumatera yang dapat membahayakan ternak dan sekaligus membahayakan nyawa manusia. Oleh karena itu, harimau sumatera diburu, ditangkap, dan dijerat. Oleh karena itu, informasi tentang aktivitas harimau sumatera menjadi penting dalam upaya melestarikan dan melindungi harimau sumatera. Metode penelitian ini adalah focal time sampling. Penelitian ini dilakukan mulai Juli 2021 hingga Agustus 2021 selama 30 hari efektif setiap hari untuk mengumpulkan data harian harimau sumatera. Obyek yang diamati pada masing-masing individu berdasarkan jenis kelamin dan umur adalah betina dewasa dan jantan remaja. Berdasarkan hasil penelitian, disimpulkan bahwa aktivitas harian tertinggi pada wanita dewasa adalah perilaku bergerak dengan persentase 21,0%, diikuti istirahat 18,7%, sosial 1,2%, perawatan 1,0%, makan dan minum 0,4%, buang air besar. dan buang air kecil 0,3%, aktivitas lain 57,4%, sedangkan untuk remaja laki-laki aktivitas tertinggi bergerak dengan persentase 12,64%, disusul istirahat 5,47%, Grooming 0,44%, sosial 0,37%, makan 0, 30%, aktivitas lain 80,32% .

Study of the yield and quality of Aceh patchouli oil from leaves and stalks at several drying times, in Bukit Batu, Palangka Raya City, Central Kalimantan. Treatment of drying time patchouli leaves and stalks to a certain extent can increase the yield of patchouli oil produced. 4 days drying treatment leaves produced the highest yield of 5.17%, stalks for 8 days produced the highest yield of 3.78% decreasing with the longer drying time. The lowest yields without desiccation (control) on leaves and stalks were 1.4% and 1.16%. Drying time treatment of patchouli leaves and stalks to some extent increased the patchouly alcohol content of patchouli oil produced. Drying time treatment for 8 days produced the highest patchouly alcohol in leaves (31.48%) and stalks (29.71%) then decreased with the longer drying time.
