AbstrakTerdapat beberapa jenis limbah kayu dari hasil proses produksi diantaranya adalah limbah serbuk kayu limbah serutan kayu, limbah serpihan kayu, dan limbah potongan kayu. Berbagai upaya dilakukan untuk memberi nilai tambah pada setiap jenis limbah kayu tersebut diantaranya adalah pembuatan kayu laminasi, kayu partikel, MDF, HDF, briket kayu, ornamen kayu, dan lain-lain. Program pengabdian ini memanfaatkan limbah potongan kayu jati menjadi produk papan kayu laminasi dan bekerja sama dengan kelompok industri meubel rumahan Desa Mangunsari di Kabupaten Semarang. Kelompok industri tersebut memiliki limbah-limbah kayu berbagai jenis dengan kuantitas yang tergolong melimpah namun belum ada perlakuan (treatment) sama sekali terkait limbah tersebut selain hanya dimanfaatkan untuk memasak dan dibuang ke lingkungan. Edukasi dan pelatihan dilakukan melalui program ini untuk membantu mitra dalam membuat limbah kayu jati menjadi papan kayu laminasi dengan memanfaatkan alat kerja seperti table saw, hand planner, hand sander, lem kayu, dan bar clamp. Poin penting pembuatan papan kayu laminasi adalah pemanfaatan table saw 8” agar bisa memotong secara presisi mengingat limbah tersebut berupa potongan kayu berdimensi kecil. Poin penting lain adalah pada proses penyatuan setiap potongan kayu dengan proses perekatan (adhesion) menggunakan lem kayu berjenis polyurethane dan pada saat bersamaan dilakukan proses penjepitan (clamping) sambungan kayu tersebut menggunakan alat bantu bar clamp agar proses pengeleman menjadi sempurna.Kata kunci: kayu laminasi, limbah kayu jati, table saw, perekatan, clampingAbstractThere are several types of wood waste from the production process such as wood dust, wood shavings, wood chips, and wood scrap waste. Various attempts were made to add value for each type of wood waste including the manufacture of laminated wood, particle wood, MDF, HDF, wood briquettes, wood ornaments, and others. This program utilizes teak wood waste into laminated wooden board products and cooperate with home-based furniture industry group in Mangunsari Village on Semarang Regency. The industrial group has various types of wood waste with a relatively abundant quantity but there is no treatment at all related to the waste other than just being used for cooking and discharged into the environment. Education and training are carried out through this program to help partners in making teak wood waste into laminated wooden boards by utilizing work tools such as table saw, hand planner, hand sander, wood glue, and bar clamp. An important point in the manufacture of laminated wooden boards is the use of a table saw 8 "in order to cut precisely because the waste is in small pieces dimension of wood. Another important point is the process of assy each piece of wood with the adhesion process using polyurethane type of wood glue and at the same time the process of clamping the wood connection using a bar clamp tool so that the gluing process becomes perfectly.Keywords: laminated wood, teak wood waste, table saw, adhesion, clamping

Home-based counseling is an emerging modality of providing mental health counseling services to clients across the lifespan. However, minimal graduate training programs and home-based agencies provide training and preparation for professional counselors. In addition, educational and professional requirements are currently ill defined. A nonexperimental pilot survey exploring home-based professional counselors work-based, and clinical supervision and training patterns was conducted. Results suggest home-based professional counselors serve diverse populations and have limited training regarding home-based competencies. Findings from the study are presented. Implications for training and practice for home-based counselors are discussed.

This study compares what schools are doing to engage parents and analyzes the efficacy of these initiatives across predominantly Black, Latino, and White schools. Using the National Center for Education Statistics’s (NCES) Schools and Staffing Surveys (SASS, 1999-2004), we specify a model that accounts both for factors associated with school policies and practices to engage parents in school- and home-based activities and the extent to which these policies affect parent involvement. Findings indicate that predominantly Black and Latino schools achieve significant gains in parent involvement as the number of policies in place to support and encourage participation increases, but that not all programs achieve the same results within or across racial contexts. Furthermore, we find leadership by minority principals, teacher attributes, responsibilities and training, as well as greater shares of Title 1 funding are positively and significantly related to school- and home-based policies across all three racial contexts.

Harvesting teak in Java always causes wood waste in the forest. The objectives of this research were to identify the shape of wood waste generated from teak harvesting activities and to determine their recovery and residual factors. The research was conducted at teak forest of Stated Owned Company (Perum Perhutani) at Banyuwangi East Java with the sampling intensity of 10 % using whole tree method. Measurement of wood waste was performed at thinning and clearcutting compartment of teak stand. The result of the study showed that the shapes of wood waste consisted of broken stem, decay wood, short trimming, branch and twig , stump, and irregular wood shape. The recovery and residual factors of the teak harvesting utilization were 79.61 % and 20.39%, respectively. Most of the wood waste were utilized by the local community for energy sources.

The present work reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from teak wood waste. Biomass from teak wood were taken out and pulverized in a micro-pulverizing mill. The powder thus obtained was activated with 40% H3PO4 and carbonized at 600 °C for 1 hour in an inert atmosphere. Physico-chemical characteristics such as  functional groups and surface morphology of the activated carbon were analyzed using FTIR spectroscopy and SEM analysis respectively. Batch adsorption experiments were performed to investigate the effects of Cr (VI) concentration, carbon dose, pH and time. The maximum adsorption capacity of Cr(VI) was found to be 1.5 g/L at pH 3 and temperature 30±1 °C. The Freundlich adsorption isotherm best represented the equilibrium data and a pseudo-second order relation represented the adsorption kinetics.

Habuk kayu dapat dimajukan, ini kerana sisa kayu dapat mengurangkankos penggunaan bahan asli dalam pengeluaran. Lantaran itu, kajian dilakukan berhubung dengankekekerasan sesuatu bahan campuran yang dihasilkan. Oleh itu, satu kajian dilakukan bagi menentukankesan penambahan habuk kayu terhadap kekerasan bahan LDPE yang akan dihasilkan. Kajian dilakukandengan melihat kesan ke atas penambahan habuk kayu dengan sifat LDPE tulen. Pemerhatian dilakukanterhadap sifat mekanikal LDPE yang dikurangkan kuantiti jisimnya dengan nisbah penambahan habukkayu sebanyak 3, 6, 9, 12 dan 15 peratus. Habuk kayu diayak menerusi pengayak yang bersaiz 200?m dan ditimbang mengikut campuran penambahan. Sampel dihasilkan menggunakan mesin suntikanpanas bagi tujuan ujian kekerasan. Keputusan ujian dianalisa bertujuan untuk membuat perbandingandengan 100% LDPE dengan peratusan HK yang ditetapkan. Ujian kekerasan secara keseluruhannyameningkat. Peningkatan paling tinggi adalah pada sampel 12% HK iaitu sebanyak 8.2%. Dalam kajianini kekerasan bahan meningkat dengan penambahan HK. Kajian lanjut tentang kekuatan bahan bolehditeruskan melalui penambahan saiz partikel pengisi yang lebih halus.   AbstractThe study involved Low Density Polyethylene (LDPE) blended with additive that is sawdust Cengal (HK).Sawdust can be developed, because wood waste can reduce the use of natural materials in production.Thus, a study was undertaken in relation to the hardness of the produced mixture. Therefore, a study wasconducted to determine the effect of wood dust on he hardness of the produced mixture LDPE material tobe produced. The study was undertaken by looking at the effect of adding the quantity of sawdust to thenature of pure LDPE. Observations were made on the mechanical properties of LDPE when the quantityof mass is reduced by increasing the sawdust ratio from 3 to 6, 9, 12 and 15 percent. Sawdust was siftedthrough a sieve with the size of 200 ?m and weighed by the addition of a mixture. Samples for hardnesstest were produced by using injection hot machine. The test results are analyzed in order to make acomparison with 100 % LDPE with HK prescribed percentage. (It is found that overall, the hardness of theproduced mixture has increase. The highest increase (8.2 %) was shown by the 12%HK sample). In thisstudy, the hardness increased with the addition of HK. Further study of the strength of the material can bepursued through the addition of finer particle size filler.
