Abstract

The existence of alternative energy from renewable materials such as charcoal briquettes is one solution to overcome the problem of reduced fossil energy, especially for household needs. Applying biomass derived from plants such as Kaliandra (Caliandra calothyrsus) as charcoal briquettes is expected to enrich plant species as an energy source. This study aims to analyze the quality of calliandra wood charcoal briquettes based on powder size and percentage of tapioca adhesive. Making charcoal briquettes is carried out through the carbonization stage, and testing the quality of the briquettes refers to SNI. 01-6235-2000. The analysis showed that calliandra wood charcoal briquettes made with 20-40 mesh powder and 15% tapioca adhesive gave the best quality. Calliandra wood charcoal briquettes (C. calothyrsus) comply with SNI 01-6235-2000 in terms of ash content and calorific value.Keywords:  charcoal briquettes, kaliandra, SNI 01-6235-2000, powder size, adhesive percentage. AbstrakAdanya energi alternatif dari bahan terbarukan seperti briket arang merupakan salah satu solusi untuk mengatasi masalah berkurangnya energi fossil, terutama untuk keperluan rumah tangga. Penggunaan biomassa yang berasal dari tanaman seperti Kaliandra (Caliandra calothyrsus) sebagai briket arang diharapkan dapat memperkaya jenis tumbuhan sebagai sumber energi. Penelitian ini bertujuan untuk menganalisis kualitas briket arang kayu kaliandra berdasarkan ukuran serbuk dan persentase perekat tapioka. Pembuatan briket arang dilakukan melalui tahapan karbonisasi, dan pengujian kualitas briket mengacu pada SNI. 01-6235-2000. Hasil analisis menunjukkan bahwa briket arang kayu kaliandra yang dibuat dengan ukuran serbuk 20-40 mesh dan perekat tapioka 15% memberikan kualitas terbaik. Briket arang kayu kaliandra (C. calothyrsus) memenuhi SNI  01-6235-2000 di parameter kadar abu dan nilai kalor.  Kata kunci: briket arang, kaliandra, SNI 01-6235-2000, ukuran serbuk, persentase perekat.

Abstract

The people of Sebatih Village, Sengah Temila District, Landak Regency still use plants for craft materials. The purpose of this study is to describe the use of plants for crafts in Sebatih Village, Sengah Temila District, Landak Regency. This study used a survey method with data collection techniques using a purposive sampling technique. Data was obtained through observation and interviews with a total 0f 93 respondents. The questions asked are how the form of utilization, processing, and what plants are used. The results showed that there were 14 types of plants used, namely taboyo (Dicranopteris linearis), pulai (Alstonia scholaris), tarap (Artocarpus elasticus), sake (Pandanus tectorius), sagu (Metroxylon sagu Rottb), anyang (Dendrocalamus sp), malamo (Donax canniformis), baman (Donnax grandis), buluh (Schizostachyum brachycladum), pasa (Schizostachyum flexuosum), tareng (Gigantochloa atter), uwi segak (Calamus caesius Blume), laban (Vitex pubescens Vahl), tarukun (Nepenthes mirabilis). Sago is a plant species that has the highest utility value of 13 other plant species with a total usability value level of 0,84. Crafts produced as many as 15 types of products such as tikar, bakul, sarang iso, tali pantongan, katoro, atap rumah, pantek, sukan, dako, pangayak, tarinak, gelang, cincin, paboyo, dan gunda. Processing of plant species used by the community in Sebatih Village, Sengah Temila District, Landak Regency is still traditional and has been carried out for generations.Keywords: crafts, plants, processing, public, utilization. AbstrakMasyarakat Desa Sebatih Kecamatan Sengah Temila Kabupaten Landak masih memanfaatkan tumbuhan untuk bahan kerajinan.

Abstract

This research aim was to know the chemical distribution of wood (Macaranga hosei King) based on its stem height/axial direction (base, middle and end of stem) and the depth of stem/radial direction (2/3 3/3 rays, 1/3 2/3 rays and 0 1/3 rays). The experimental includes the percentage of alcohol benzene-soluble extractive content, lignin content, holocellulose and ?- cellulose. The result showed base on stem height that the percentage of alcohol benzene soluble extractive, lignin, holocellulose and ?- cellulose content decrease from the base, middle and to the end of stem. Base on depth of stem, the result showed that the percentage of alkohol benzena-soluble extractive content, lignin content, holocellulose and ?- cellulose decreasing from 2/3 3/3 rays, 1/3 2/3 rays and to the part of 0 1/3 rays. The interaction of stem height and depth of stem has significantly affected to the percentage of alcohol benzene-soluble extractive content. The overall result showed that Mahang wood is suitable for used as sawn timbers, wood panels and raw materials for pulp and paper. Keywords: chemical properties, Macarang hosei, stem height, stem depth.

Abstract

This research was undertaken mainly to isolate and identify antitermitic substances that may be prospective as wood natural preservative from the bark of Acacia auriculiformis A. Cunn. ex Benth. The woodmeal of the samples were extracted with acetone. The acetone extract was then fractionated into n-hexane soluble fraction, ethyl ether soluble fraction, ethyl acetate soluble fraction, and insoluble fraction. The antifeedant bioassay test was carried out by treating paper discs with extracts at six level of concentration i.e. 0%, 2%, 4%, 6%, 8%, and 10% (w/w). The bioassay test revealed that ethyl ether soluble fraction exhibited high toxicity to subterranean termite Coptotermes curvignathus Holmgren (concentration of 4% has been indicated very strong activity).
