Penelitian ini bertujuan untuk mengetahui jumlah Persediaan Bahan Baku Kayu Ulin (Eusideroxylon zwageri B. & T.) dalam Pembuatan Kusen Pintu di UD. Meubel Perdana Sampit Kabupaten Kotawaringin Timur. Bahan baku kayu ulin yang digunakan untuk pembuatan kusen pintu pada UD. Meubel Perdana terkadang mengalami peningkatan dan penurunan dari tahun 2012-2016 yang dimana tahun 2012 pemakaian masih mengalami kenaikan, di tahun 2013 pemakaian bahan baku mengalami penurunan dari tahun 2012. Tahun 2014 pemakaian bahan baku mengalami kenaikan yang signifikan dari tahun 2012, di tahun 2015 pemakaian bahan baku kembali mengalami penurunan di bandingkan pemakaian tahun 2014. Tahun 2016 pemakaian bahan baku naik dari tahun 2015. Adapun kenaikan penggunaan bahan baku kayu ulin tersebut disebabkan karena permintaan dari konsumen dalam pembuatan kusen pintu semakin meningkat. Pemakaian bahan baku enam bulan pertama tahun 2016 yaitu 8,352 m³, sementara 6 bulan kemudian di tahun 2017 yaitu 5,760 m³, maka dapat dilihat adanya penurunan pemakaian bahan baku sebesar 2,592 m³. atau 31,034 %. Hal ini disebabkan karena menurunnya permintaan konsumen dan diduga karena adanya persaingan usaha dalam pembuatan kusen pintu sehingga kebijaksanaan dalam perbelanjaan bahan baku dikurangi sesuai dengan perkiraan pemakaian bahan baku. Pemesanan kembali dapat dilakukan apabila persediaan bahan baku telah mencapai 3,023 m³. Jumlah optimum pemesanan yang ekonomis pada tahun 2017 adalah sebanyak 5 kali, dimana setiap kali pemesanan sebanyak 3,343 m³, dengan jarak dari setiap pemesanan adalah ± 50 hari.

Lesser wood supplies from the forest, which impact on the increasing quality of wood, but timber is still in demand for construction materials. Fruit wood can be used as an effort or alternative to overcome supply shortages or availability of wood. However, most fruit wood has a durable class and low durability. The purpose of this study is to analyze the durability of 3 types of fruit wood, namely, durian wood, rambutan wood and jackfruit wood preserved with preservatives of tembelekan leaf extract, to determine the degree of damage to wood destroying pest attacks. The method used is the length of immersion 3 days, 5 days, and 7 days, with each replication 3 times, with sample tests totaling 27, and 9 test samples as controls, so the total number of test samples is 36. Conclusions obtained from this study is, the degree of damage of wood preserved with the extract of tembelekan leaves has the highest and lowest average value of 37.86% - 26.72%, this condition can be seen that the wood is included in conditions of moderate attack.Keywords: Durian wood; Rambutan; Jackfruit; Tembelekan leaf extract; Degree of damage

The wood needs continue to rise causing the declining supply of wood with durable high grade. Addressing the needs of the wood is currently much used wood from different types of fruits, one of which is the bnayak mango wood is used as a material for furniture where the wood has a low grade durability durable V. This research was held the Wood Chemistry Laboratory of the Faculty of Forestry ULM using natural preservation of soursop leaves and borax chemical preservatives. The size of the wood that used in this research is 25 cm x 5 cm x 2.5 cm. The findings of this research are absorptions, retention, weight loss and degree of damage with a simple Randomized Analysis Design (RAL). Preservation of Mango wood (Mangifera indica) with soursop leaves by using 200 soursop leaves with (6.04% concentration) is the most optimal preservation value of 84.26 kg / m3 while using Borax as preservative with (10% concentration) has preservation value of 76 , 55 kg / m3. The lowest average degrees of termite attack damage value is the usage of 200 sheets soursop leaves with (6.04% concentration), while the highest average value is The usage of 100 sheets soursop leaves (with 3.04% concentration). The highest average value of Weight loss due to termite attacks is the usage of Borax with 15% concentration, while the lowest is the usage of 200 sheets of soursop leaves (6.04% concentration).

ABSTRACT. Yield a benchmark of success or failure of a production achievement, while productivity becomes a measure of achievement of production with the desired result. The purpose is to know the yield and productivity of barecore from meranti wood pith waste (Shorea sp.) in PT. Surya Satrya Timur.That method that being used is collection a primary dan secondary data. Primary data were obtained by direct observation and interview. Primary data is conducted on each unit of activity, so it can know the amount of input, output and waste. While the secondary data is the location of research and related institutions to support the research data. The average yield obtained was 32.95% with the highest yield on one repeat to 40.65% and the lowest yield on the fifth repeat of 26.18%. Yield does not have maximum results because the yield is less than 50%. The average productivity gained was 0.95 m3/h with the greatest productivity in the third repeat of 1.66 m3/h and the lowest productivity on the fifth repeat of 0.34 m3/h. Further research is suggested to do further research on the processing of barecore from pith waste of meranti wood (Shorea sp.) in PT. Surya Satrya Timur on the influence of other factors such as machine layout with productivity, the effect of worker's characteristics on productivity and the ratio of yield between meranti sprouts and other wood chips.Keywords: Yield, Productivity, Barecore, Meranti Wood, PithABSTRAK.

ABSTRACT. The effectiveness of borax in cold soaking method on sengon wood and acacia against dry wood termites’ attack (Cryptotermes cynocephalus Light). Thiskstudykaims to determinekthe resilience of Sengon wood (ParaseriantheskFalcataria) andkAcacia (Acacia Mangium) and to get the information about the effectiveness of cold soaking method with borax against the attack of dry wood termites. The resistance test due to to dry wood termites used the percentage of term loss and also the mortality of termites. The analysis that has been used to find out the effectiveness of cold soaking method with borax is by using complete randomized design. The results of this research are acacia wood has medium resistance to termite test with the score in between 4,132 to 6,217 while sengon wood is classified between 8,580 up to 10,834. Cold soaking with an effective borax is used in sengon and acacia wood as a preservative material against the attack of dry wood termite because it contains active toxic ingredients.
