Abstract

This study aims to determine the volume of wood waste (in units of m3 and %) in IUPHHK-HA PT. Dwimajaya Utama. The research was carried out in cutting plots K-18 (RKT 2015) and felling plots J-21 (RKT 2016). As many as 8 units of sample plots measuring of 100 m x 100 m were purposively selected and then the waste resulted from 56 trees that had been felled were observed. The results showed that the woods potential on the cutting plot K-18 were 229.32 m3 while on plot J-21 were 200.03 m3, total volume of waste from the two cutting plots were 429.35 m3. Second, the reali-zation of logs production on the felling plot K-18 were 165.29 m3 (72.07%) and on plot J-21 were 145.73 m3 (72.86%) and the total from the two cutting plots were 311.02 m3 (72.44%). Thirdly, the mount of felling waste on felling plot K-18 were 64.05 m3 (27.93%) and on plot J-21 were 54.28 m3 (27.14%); resulting the total waste from both felling plots were 118.33 m3 ( 27.56%). Percentage of waste to production on felling plot K-18 were 38.75%, and on plot J-21 were 37.25%, and the mean from the two cutting plots were 38.00%. Forest potential structure for the two logging plots, namely timber potential around 429.35 m3, realized logs production of 311.02 m3 (72.44%) and resulted waste around 118.33 m3 (27.56%). The relatively low percentage of felling waste indicates that the application of RIL (Reduce Impact Logging) in logging activities is relatively successful.

Abstract

Penelitian bertujuan untuk mengetahui persepsi masyarakat pada kegiatan rehabilitasi hutan dan lahan (RHL), dan hubungan antara tingkat kesejahteraan keluarga dengan persepsi masyarakat. Penelitian ini merupakan studi kasus, dengan objek penelitian adalah masyarakat Desa Malawaken. Penelitian ini bersifat deskriptif, memakai nilai skoring, kemudian dialakukan analisa dengan Uji Tanda dan Uji Chi Kuadrat. Hasil penelitian menunjukkan bahwa: (a) masyarakat mendukung kegiatan RHL, (b) ada hubungan antara tingkat kesejahteraan keluarga dengan persepsi masyarakat terhadap kegiatan RHL, dan (c) makin tinggi tingkat kesejahteraan keluarga makin besar dukungannya terhadap kegiatan RHL.

Abstract

Central Kalimantan has many types of wood such as Rengas (gluta sp), Bangkirai (shorea laevifolia endert), and Agathis (agathis spp). The third type of woods are found in the company of furniture as a result of waste in powder form so that it can be utilized for the manufacture of charcoal briquettes. The purpose of the research is to find out the characteristics of charcoal briquettes from wood waste Rengas, Bangkirai, and Agathis which refers to the Indonesian National Standard (SNI 01-6235-2000). The treatment of this research done on Bangkirai wood, Rengas, and Agathis which have different density with 5 replications so that the samples obtained 15 pieces. Data analysis was conducted to determine the effect of the treatment on the character of the studied and if it has significant effect then it is analyzed test difference average middle value that is specified by Coefficient Value of Diversity. Charcoal briquettes testing generally meets Indonesian National Standard (01-6235-2000) on charcoal briquettes except for volatile substances. The research data finding from these three types of wood which examined showed that the type of Bangkirai wood powder has the best charcoal briquette quality because of lower water content is at 5.05%, the higher density is 0.72 g/cm3, the ash content is 1.9% , carbon bound is 63.30%, volatile substance content is 29.75%, press firmness is 41.67kg/cm2, and calorific value is 6958.94 kal/g
