Abstract

Rotan jernang (Daemonorops micracantha Becc.) adalah tumbuhan palem-paleman yang memiliki peran penting sebagai pewarna alami bagi kerajinan anyaman masyarakat Suku Dayak di Kabupaten Sintang. Namun demikian, populasinya semakin berkurang akibat habitat alaminya yaitu hutan primer dataran rendah yang semakin berkurang akibat konversi lahan menjadi area perkebunan dan pemanenan berlebih oleh masyarakat. Penelitian ini bertujuan untuk mengetahui karakteristik morfologi Rotan jernang yang ada di ekosistem hutan rawa gambut dan potensi pemanfaatannya oleh masyarakat lokal setempat di Kawasan ekobudaya Penam Sengkuang Lebuk. Penelitian ini menggunakan metode deskriptif kualitatif dalam mengumpulkan dan analisis data. Data karakteristik morfologi Rotan jernang dikumpulkan menggunakan 3 plot ukuran 10 x 10 m pada Penam Sengkuang Lebuk. Sedangkan data potensi rotan jernang didapatkan melalui wawancara mendalam (In-depth interview) terhadap tokoh masyarakat di Desa Empaka Kebiau Raya, Kabupaten Sintang. Analisis data pada penelitian ini menggunakan analisis deskriptif kualitatif serta data ditampilkan dalam bentuk tabel, gambar, deskripsi dan kutipan wawancara. Hasil penelitian tentang karakteristik morfologi Rotan jernang (Daemonorops micracantha) di Penam Sengkuang Lebuk memiliki kesamaan dengan anggota genus Daemonorops lainnya. Perbedaan utama terdapat pada duri di selubung daun D. micracantha berbentuk bulat yang berbeda dengan yang lainnya. Secara morfometri, ukuran diameter dan panjang pelepah memiliki variasi namun hal tersebut karena adanya perbedaan spesies dan habitat hidup Rotan jernang. Pemanfaatan Rotan jernang di Desa Empaka Kebiau Raya masih hanya digunakan sebagai pewarna alami. Namun potensi ekonomi Rotan jernang yang tinggi dapat menjadi sumber pemanfaatan lain sehingga Rotan jernang dan seluruh ekosistem di Penam Sengkuang Lebuk dapat lestari.

Abstract

The improvement of wood finishing quality extends beyond the application of paint; it also encompasses techniques such as heat modification. One prominent method currently employed for enhancing wood finishing quality is the yakisugi or shou sugi ban technique. This technique has regained popularity due to its ability to produce unique surface patterns and enhance the dimensional stability of wood. However, this technique has not been widely applied to commercial wood types in Indonesia. Therefore, this research aims to evaluate the burning quality and dimensional stability of pine and sungkai wood after the burning process. The research results indicate that the surface characteristics of burned pine and sungkai wood yield distinct and unique patterns. Color change tests reveal no significant difference between pine and sungkai woods, both exhibiting a clove brown hue. Surface characteristics post-burning show a decrease in paint adhesion with the prolonged burning process, inversely proportional to the contact angle values produced. Dimensional stability is measured by percentage volume expansion and anti-swelling efficiency. The yakisugi technique demonstrates the capability to enhance the dimensional stability values of sungkai and pine woods by a notable margin of 30-50%.  Subsequent research is crucial for observing the chemical changes occurring on the wood surface after burning. Keywords: dimensional stability, pine wood, sungkai wood, wood finishing, yakisugiAbstrakPeningkatan kualitas finishing kayu tidak hanya dalam bentuk proses pemberian cat, tapi juga bisa dalam bentuk teknik modifikasi panas. Salah satu jenis modifikasi panas yang saat ini banyak dilakukan terutama dalam hal peningkatan kualitas finishing kayu adalah metode yakisugi atau shou sugi ban. Teknik ini Kembali popular karena mampu menghasilkan corak permukaan kayu yang unik dan mampu meningkatkan nilai stabilitas dimensi kayu. Namun demikian, teknik ini masih belum banyak diaplikasikan untuk jenis-jenis kayu komersil Indonesia. Maka dari itu penelitian ini bermaksud mengevaluasi kualitas pembakaran dan nilai stabilitas dimensi setelah proses pembakaran pada kayu pinus dan sungkai.  Hasil penelitian menunjukkan bahwa karakteristik permukaan kayu pinus dan sungkai setelah pembakaran menghasilkan corak yang berbeda dan unik. Uji perubahan warna menunjukkan hasil yang tidak berbeda antara jenis kayu pinus dan sungkai yaitu clove brown. Karakteristik permukaan kayu setelah pembakaran menunjukkan nilai daya lekat cat yang semakin rendah seiring bertambah lamanya proses pembakaran dan berbanding terbalik dengan nilai sudut kontak yang dihasilkan. Nilai stabilitas dimensi ditunjukkan dengan parameter persentase pengembangan volume dan anti swelling efficiency. Teknik yakisugi mampu meningkatkan nilai kestabilan dimensi kayu sungkai dan pinus sebesar 30-50%. Penelitian selanjutnya penting dilakukan pengamatan pada perubahan yang terjadi secara kimia pada permukaan kayu setelah pembakaran. Kata kunci: finishing kayu, pinus, sungkai, stabilitas dimensi, yakisugi

Abstract

Mining in Indonesia uses an open pit mining system that has the potensial to cuase loss of forest vegetation and damage to the physical, chemical and biological properties of the soil. This soil damage result in former mining land to be nutrient poor so that it requires a supply of nutrients form outside in order to support plant growth. The purpose of this study was to determine the effect of the use of compost plus and natural mulch on the growth of reclaimed plants in the former mining land. The research was conducted in the post-mining area of PT Asmin Bara Bronang, Sektor Kalimaya, Kabupaten Kapuas, Kalimantan Tengah. The study used a two-factor complete randomized design (RAL) with two repetitions. The first factor is the type of plant (T); Johar (T1), Sengon (T2), and Bintaro (T3). While the second factor is compost plus ± mulch (p): P1 (control treatment), P2 (using compost plus without mulch) and P3 (combination of compost plus and mulch). The results showed that the treatment of plant species does not affect the height of the plant but significantly affect the diameter of the STEM and the number of leaves, while the treatment of compost and mulch significantly affect the plant height, stem diameter and number of leaves. The best results of measuring plant growth parameters were obtained from the combination of compost plus and mulching treatment (P3).Keywords: compost plus, natural mulch, growth, reclamation plants, ex-mining land.

Abstract

Wood composite product variation was highly increased and the quality also became improved rapidly since the methods to improve the composite products became more sophisticated. This condition escalated the demand for fast-growing species of wood as raw material. The increased production from fast-growing species of wood also increased the waste generated from the production. The objective of this study was to increase the utilization of sawmill waste as materials for i-beam production for construction purposes. The waste from sengon and pulai wood was converted into the flange and web components with a 3 cm in width and height variation of 1.5, 3, and 5 cm. The flange and web were adhered with isocyanate (hardener 10% NH4Cl) with glue-spread weight 200 g/m2 and then nailed with a 7” nail on each flange surface every 20 cm. The density of the i-beam produced was higher than the control wood but not directly correlated with wood mechanical properties (MOE & MOR). The mechanical properties of the i-beam produced were still relatively lower than the solid control wood. To achieve higher mechanical properties, the flange width should be reduced and the assembling design between the flange and the web should be improved further.Keywords: fast-growing wood species, i-beam, sawmill waste. AbstrakProduk komposit dari hasil pengembangan teknologi peningkatan mutu semakin bervariasi dengan karakteristik yang lebih baik dari bahan bakunya. Kondisi ini mengakibatkan permintaan terhadap jenis kayu cepat tumbuh semakin tinggi. Peningkatan produksi dari jenis kayu cepat tumbuh tentunya juga akan menghasilkan limbah pengolahan yang semakin tinggi. Salah satu limbah yang paling besar dari segi volume dan berat adalah sebetan sisa penggergajian. Maka dari itu penelitian ini bertujuan untuk meningkatkan pemanfaatan limbah gergajian lebih luas menjadi produk konstruksi balok-I. limbah sebetan kayu sengon dan pulai dibentuk menjadi komponen flange dan bagian web dengan lebar 3 cm dengan variasi tinggi sebesar 1.5 cm, 3 cm, dan 5 cm. Proses penyambungan bagian flange dan web direkatkan dengan isosianat (hardener NH4Cl 10%) dengan berat labur 200 gr/m2 kemudian pemberian paku berkuran 7” pada masing-masing permukaan flange setiap jarak 20 cm. Kerapatan balok-I yang dihasilkan lebih tinggi daripada kayu kontrol namun tidak berbanding lurus dengan kekuatan. Nilai MOE dan MOR balok I kayu sengon dan pulai rata-rata sebesar 24241 kg/m2 dan 29210 kg/m2. Sementara nilai MOR rata-rata sebesar 144 kg/m2 untuk balok I kayu sengon dan 108 kg/m2 untuk balok I kayu pulai. Sifat mekanis kayu utuh / kontrol masih lebih tinggi dibandingkan dengan sifat mekanis balok-I yang dihasilkan. Untuk mendapatkan nilai kekuatan yang lebih tinggi, pada pembuatan balok-I selanjutnya disarankan untuk mengurangi lebar komponen flange dan mengoptimalkan desain sambungan antara komponen flange dan web.Kata kunci: Kayu Cepat Tumbuh, Balok-I, Limbah Gergajian

Abstract

The Sonor farming system is an agricultural system that clears land by burning, which is a tradision arried out by the people of Secondong Village. The Sonor system is one of the couses of land fires in South Sumatra. This study aims to analyze community community knowledge of sonor farming systems, analyze the factors that influence people's knowledge of sonor farming and community attitudes that can be done to prevent sonor farming. The research was conducted in Secondong Village, Pampangan District, OKI Regency, South Sumatra Province in August 2019. Using a survey method with descriptive qualitative data analysis and a Likert Scale test. The results showed that 77% of the people of Secondong Village carried out land burning, the people of Scondong Village had quite high knowledge about sonor farming systems which were considered an effective and efficient and cost-effective method. There are two factors that affect the public's interest in burning land, namely the lack of public understanding of the impacts of land burning (75%) and habits that have been passed down from generation to generation (73%), the absence of counseling so that there is no land clearing in other ways. Communities have good potential to prevent sonor farming systems (82%) if supported by extension activities and environmentally friendly technologies for clearing agricultural land.
