Abstract

Mistletoe is hemiparasitic plants (macroparasite) on seasonal and annual plants include trees, however, mistletoes are also beneficial as key species that fill in the ecological niche, and a potential to non-wood forest product such as medicinal plants as one of them. The objectives of this research are to identify species of teak mistletoes at Padangan Clonal Seed Orchard (CSO) in Perum Perhutani and to aim its posibilities as medicinal plant. The inventory methods on species of teak mistletoes was carried out in compartements/blocks of teak clones that are designated as Observation Sample Plots (OSPs/PCP) of the attack intensity from low, medium, high, control; and four units Observation Measurement Plots (OMPs/PUP) on each OSPs/PCP. Continously, it was analized by comparing the same species of mistletoes on other host trees as reference which was efficacious to be used as medicinal plant. Three species of mistletoes parasitizing teak clone stands were identified as Dendrophthoe pentandra (L.) Miq. of family of Loranthaceae which is also attacking other host trees, Macrosolen tetragonus (Blume) Miq. of family of Loranthaceae too, Viscum articulatum Burm. F. of family of Santalacea/Viscaceae that is hyperparasite on two other mistletoes. The comparison with the same teak mistletoe but on different host trees shows that including D. pentandra and V. articulatum have the potential for hypertension treatment. D. pentandra is used too for medicine to cure ilness, wounds, fester and recovery from parturition. Known that chemical content this mistletoe comprise of flavonoid ingrident, fenolat acid (terulat acid, para hidroksi benzoate acid, kumarat acid, protokatekuat acid and vanilat acid. As for the utilization of M. tetragonus hasn’t been discovered up to this moment.Key words: mistletoe, identification, teak clone, non-wood forest product, medicinal plant

Abstract

Growth and Yield Analysis of Peronema canescens Jack. in Kalimantan          Sungkai (Peronema canescens) is a native and local species and one of some commercial trees which has a good prospect to be developed in timber estate in Kalimantan.This research was aimed to analyse sungkai plantation, neither the living percentage, productivity, economic cutting cycle, and also its profit. The data analysis was using the average of trees diameter, high and volume, mean annual increment, polynomial equation modelling and financial analysis i.e. net present value (NPV), benefit cost ratio (BCR) and internal rate of return (IRR). The research had been conducted at the community plantation in Kapuas District, Central Kalimantan Province since 1998 to 2010.  The result of this research showed that living trees precentage at 12 years old was 89.7%, mean annual increment and its density were 10,14 m3 ha-1  and 997 tree/ha respectively. Equation modelling of sungkai plantation was y = 2,073 + 1,6623x - 0,0165x2 (R2= 84,05%). In the bank rate of 9% per year, the economic cutting cycle of this plantation was 15 years with net present value was NPV 58,49 million per ha. BCR 7,64 and IRR 11,75 If the bank rate of 6% and 12% per year, then net present value at the 15 years were NPV 92.65 and 36.6 million per ha respectively. The sangtein was suitable as timber estate and to increase the productivity of former shifting cultivation, scru, and low potential forests which were widespread, especially in Kalimantan.Keywords :  Growth and yield, mean annual increment, Peronema canescens, economic cutting cycle ABSTRAK        Sungkai adalah jenis tanaman komersial lokal dan asli yang mempunyai prospek baik untuk dikembangkan dalam hutan tanaman Kalimantan. Penelitian ini bertujuan untuk mengetahui prosen hidup, produktivitas, siklus tebang optimum, dan keuntungan finansial dari tanaman sungkai. Penelitian dilakukan di hutan tanaman rakyat, Kabupaten Kapuas Provinsi Kalimantan Tengah. Obyek penelitian ialah tanaman sungkai yang ditanam sejak tahun 1998 pada tipe tanah Ultisol. Analisis data menggunakan nilai rataan diameter, tinggi dan volume, riap tahunan rata-rata tahunan, persamaan regresi, NPV, BCR dan IRR. Hasil penelitian menunjukkan bahwa pada umur 12 tahun prosen hidup tanaman mencapai 89,7 %, riap tahunan rata-rata 10,14 m3 ha-1 year-1 dengan kerapatan 997 pohon/ha. Model pertumbuhan tanaman sungkai ialah y = 2,073 + 1,6623x - 0,0165x2 (R2= 84,05%). Pada tingkat suku bunga pinjaman 9% per tahun, tanaman sungkai mempunyai siklus tebang ekonomi selama 15 tahun dengan nilai NPV Rp. 58,49 juta/ha, BCR: 7,64 dan IRR: 11,75%. Pada tingkat suku bunga pinjaman 6% dan 12% per tahun, maka pada siklus tebang selama 15 tahun, nilai NPVnya masing – masing menjadi Rp. 92,65 juta/ha dan Rp. 36,6 juta/ha. Tanaman sungkai sangat sesuai dikembangkan dalam hutan tanaman dan untuk meningkatkan produktivitas lahan bekas perladangan berpindah, semak belukar dan hutan potensi rendah yang tersebar luas, khususnya di Kalimantan.Kata kunci : Pertumbuhan dan hasil, riap tahunan rata – rata, Peronema canescens, siklus tebang ekonomi

Abstract

Pendidikan merupakan bagian terpenting dari kehidupan, dan harus sejalan dengan perkembangan zaman dalam menghadapi tantangan yang terus berubah   Wabah Covid-19 telah melanda dunia Pendidikan Tinggi yang memaksa semua Perguruan Tinggi di Bogor menerapkan sistem belajar jarak jauh dan sekaligus melakukan merdeka belajar kampus merdeka yang harus memperhatikan kompetensi lulusan pada perguruan tinggi swasta. Penelitian ini bertujuan untuk menganalisis kinerja MBKM dan pencapaian indikator kinerja utama Perguruan Tinggi setelah pelaksanaan MBKM khususnya kelas yang kolaboratif dan partisipatif.  Metode penelitian yang digunakan adalah secara diskriptif dan uji beda.  Analisis data meliputi reduksi, penyajian, dan penarikan kesimpulan.  hasil penelitian dapat disimpulkan bahwa (1) Kinerja pembelajaran MBKM perguruan tinggi telah dilaksanakan dengan baik selama pandemic covid 19 ataupun era industry 4.0 dengan tingkat kepuasan mahasiswa puas, dan (2) Pembelajaran pada era merdeka belajar kampus merdeka berbeda nyata dengan pembelajaran sebelumnya pada semua parameter pencapaian IKU khususnya kelas yang kolaboratif dan partisipatif dimana menghasilkan ningkatan pada seluruh parameter.
