Abstract

ABSTRAK Jagung (Zea mays) merupakan salah satu komoditas pertanian utama yang ditanam oleh para petani di Desa Bangun Sari, Pesawaran. Hasil dari budidaya tanaman jagung menghasilkan limbah biomassa berupa tongkol jagung yang jumlahnya cukup besar. Namun, sebagian besar dari limbah biomassa tongkol jagung ini belum dikelola dengan optimal di Desa Bangun Sari. Seiring waktu, limbah biomassa tongkol jagung ini hanya diabaikan dan dibakar, menyebabkan timbulnya isu lingkungan. Limbah biomassa tongkol jagung berpotensi untuk dikonversi menjadi biochar yang memiliki banyak manfaat termasuk sebagai bahan pembenah tanah (ameliorant). Kegiatan pengabdian kepada masyarakat ini menerapkan teknologi produksi biochar menggunakan single drum kiln karena mudah diaplikasikan dan biaya produksi relatif murah. Selain itu, petani juga didampingi dalam desain dan pengemasan produk biochar. Hasil evaluasi menunjukkan peningkatan signifikan dalam pengetahuan dan pemahaman peserta terkait produksi dan manfaat biochar. Produk biochar dikemas dalam dua bentuk yaitu yang sudah dihaluskan dan masih utuh. Kegiatan pengabdian kepada masyarakat ini berkontribusi dalam memanfaatkan limbah biomassa jagung menjadi produk bernilai ekonomi dan lingkungan yang bermanfaat. Kata Kunci: Biochar, Limbah Tongkol Jagung, Single Drum Kiln  ABSTRACT Corn (Zea mays) is one of the main agricultural commodities grown by farmers in Bangun Sari Village, Pesawaran. The corn plantation results in a significant amount of biomass waste in the form of corncobs. However, most of the corncob biomass waste has not been managed optimally in Bangun Sari Village. The corncob biomass waste is neglected and burned over time, causing environmental problems. Corncob biomass waste has the potential to be converted into biochar which has many benefits including as a soil amendment (ameliorant). This community service activity applies biochar production technology using a single drum kiln because it is easy to apply and production costs are relatively cheap. In addition, farmers are also assisted in the design and packaging of biochar products. The evaluation results showed a significant increase in participants' knowledge and understanding regarding the production and benefits of biochar. Biochar products are packaged in two forms, namely solid and powder forms. This community service activity contributes to utilizing corn biomass waste into useful economic and environmentally valuable products. Keywords : Biochar, Corncobs Waste, Single Drum Kiln

Abstract

Wood panel products mainly use formaldehyde-based adhesives that release free formaldehyde and potentially cause health problems. This study aimed to develop a free-formaldehyde adhesive from cat’s eye damar (CED) resin as an alternative adhesive for plywood production. The low-quality CED resin was used to increase the added value of the resin. The adhesive formulation consists of a ratio of 30:70 (CED:benzene) dissolved for 15 minutes at 45°C. The plywood was manufactured using glue spread rates of 200, 250, and 300 g/m2 with an addition of 10% tapioca flour and hot pressed using a pressure of 2.45 MPa at 120°C for 6 minutes. The CED-based adhesive produced has a solid content of 28.76%, a pH value of 5.93, a gel time value of 70.05 minutes, and a viscosity value of 4.02 mPa.s. Fourier-transform infrared spectroscopy analysis stretching of the C-H group, indicating an alkane compound. Plywood’s physical and mechanical properties bonded with CED-based adhesive increased with higher glue spread application. Utilizing a glue spread of 300 g/m2 could produce plywood with comparable physical and mechanical properties to the urea-formaldehyde-bonded plywood. Keywords: cat’s eye damar, dynamic mechanical analysis, formaldehyde-free adhesive, plywood, Shorea javanica

Abstract

Taman Hutan Raya Wan Abdul Rachman (Tahura WAR) terbagi menjadi 7 blok pengelolaan yaitu, blok perlindungan, blok pemanfaatan, blok koleksi tumbuhan dan satwa, blok tradisional, blok rehabilitasi, blok religi budaya atau sejarah, dan blok khusus. Khusus blok tradisional, masyarakat diberikan izin usaha pemanfaatan Tahura WAR melalui skema kemitraan kepada masyarakat yang sudah terlanjur menggarap Kawasan hutan. Usaha yang dapat dilakukan pada blok tradisional antara lain berupa usaha jasa lingkungan dan usaha hasil hutan bukan kayu. Akan tetapi, produk-produk ini belum sepenuhnya dapat dipasarkan oleh masyarakat. Hal ini terjadi antara lain karena belum tingginya jiwa kewirausahaan yang dimiliki masyarakat, kurangnya promosi, rendahnya kualitas produk yang dihasilkan, sistem pemasaran yang kurang baik dan lain sebagainya. Setelah pemberian materi oleh narasumber, masyarakat menjadi faham tentang pemasaran hasil hutan bukan kayu dimulai dari nilai tambah produk sampai pada pemasaran dengan teknologi terkini. Menurut ketua Gapoktan Manunggal Sejahtera, KTH Sejahtera 1 dan 6, kegiatan ini tidaklah mudah dilakukan jika tanpa kerjasama yang baik antara suami dan istri karena pada umumnya, suami suatu keluarga di Desa Pesawaran, Kecamatan Kedondong, Kabupaten Pesawaran bekerja penuh di lahan setiap harinya. Dengan demikian perlu kerjasama atau pembagian tugas yang baik dengan para istri atau anggota keluarga lainnya. Oleh karena itu, pembagian tugas menjadi sangat penting di setiap keluarga petani di sekitar hutan, selain itu kelembagan pada kelompok wanita dan pemuda juga perlu segera dibentuk dan diperkuat sehingga masing-masing pihak dapat berperan dan mendukung kesejahteraan keluarga maupun desa.

Abstract

 Penggunaan sumber energi dari fosil secara terus menerus mengakibatkan pasokan minyak bumi menjadi terbatas, sehingga dibutuhkan inovasi energi terbarukan. Tandan kosong kelapa sawit (TKKS) merupakan salah satu limbah padat dari industri minyak sawit yang potensial untuk digunakan sebagai energi terbarukan karena ketersediaannya yang melimpah dan harga bahan baku yang relatif murah. Sifat-sifat TKKS dapat ditingkatkan menggunakan metode torefaksi. Torefaksi adalah perlakuan termokimia pada kisaran  suhu 200-300°C dengan kondisi inert (oksigen terbatas).  Penelitian ini bertujuan untuk mengetahui perubahan sifat fisis pelet TKKS melalui torefaksi dengan menggunakan electric furnace (EF). Torefaksi pelet TKKS pada penelitian ini menggunakan suhu 280°C dengan durasi 20 menit.  Pengujian pelet TKKS meliputi perubahan warna, kerapatan, kadar air, dan ketahanan terhadap perendaman air. Hasil penelitian menunjukkan bahwa warna pelet tandan kosong kelapa sawit berubah total setelah torefaksi dengan nilai perubahan warna (ΔE*) sebesar 14,97. Kerapatan awal pelet sebesar 0,58% g/cm3 menurun dan setelah torefaksi menjadi 0,48 g/cm3. Kadar air awal pelet tandan kosong kelapa sawit sebesar 11,54% menurun setelah torefaksi menjadi 6,66%. Uji ketahanan terhadap air menunjukkan bahwa pelet yang ditorefaksi lebih tahan terhadap air dibandingkan pelet yang belum ditorefaksi, sehingga akan sangat menguntungkan ketika pelet disimpan dalam waktu yang lama dan pada kondisi lembab. Kata kunci: sifat fisis, tandan kosong kelapa sawit, torefaksi, warna.

Abstract

The purpose of this study was to evaluate the characteristic of cross-laminated timber (CLT) made from puspa (Schima wallichii) wood, coconut (Cocos nucifera) trunk, and their combination using a polyurethane (PU) adhesive. The manufacturing of CLT begins with the characterization of the adhesive and wood materials used in this study. The CLT panels are made with dimensions of 100 cm × 30 cm × 3.6 cm. The laminate was organized into three layers with the face/core/back, namely puspa wood (PPP), coconut trunk (CCC), and their combination (PCP and CPC), perpendicular to each other using polyurethane adhesive with a glue spread of 160 g.m-2. The physical and mechanical properties of the CLT were assessed according to the JAS 3079 (2019) standard. The results showed that the polyurethane adhesive used in this study could cure optimally at a temperature of 30°C for 200 minutes. Puspa wood and coconut trunk had different physical and chemical properties but had similar wettability to polyurethane adhesives. The physical and mechanical characteristics of coconut CLT were better than puspa CLT. Based on the overall test results, the puspa hybrid CLT is better than the single wood species of the CLT. In contrast to coconut hybrid CLT, the single CLT of CCC was better than its hybrid CLT. Keywords: Coconut trunk, cross-laminated timber, layer combination, polyurethane adhesive, puspa wood

Abstract

The imperative transition to renewable energy drives the need for innovation. Biomass, particularly wood pellets, has demonstrated poor performance in co-firing scenarios. This study employed pyrolysis to convert wood pellets into biochar with improved fuel quality. The biochar production and characterization were investigated at pyrolysis temperatures of 400°C to 500°C. The findings revealed significant improvements: the observed fixed carbon content increased from 67.2% to 78.8%, and the calorific value increased 1.2 times higher within the pyrolysis temperature increased. On the other hand, as the pyrolysis temperature increased from 400°C to 500°C, biochar yields decreased from 49% to 37%. Thermogravimetric (TG) analysis revealed distinct weight loss during heating, illuminating component volatilization and residue accumulation. Furthermore, Fourier transform infrared (FTIR) spectroscopy elucidated structural changes, demonstrating the evolution of cellulose and hemicellulose into aromatic structures. Ultimately, these insights into biochar characteristics informed the optimization of pyrolysis processes, contributing to the production of superior biochar for renewable energy applications. Keywords: biochar, biomass, carbon storage, pyrolysis, wood pellet

Abstract

Betung bamboo (Dendrocalamus asper) and andong bamboo (Gigantochloa pseudoarundinacea) are non-timber forest products that can be used as a substitute for wood. However, both bamboos have light colors that are less aesthetic and susceptible to fungal and pest damage. Therefore, it is necessary to modify the bamboo. One of the modification methods used is oil heat treatment (OHT). This research aims to determine the effect of OHT on the color of betung and andong bamboo. This research was carried out the OHT using palm oil at temperatures of 180°C, 200°C, 220°C and 240°C for 2 hours. Color parameter measurements were observed using a colorimeter that implemented the CIE-Lab color system. The color parameters measured include brightness (L*), red/green chromaticity (a*), yellow/blue chromaticity (b*), and overall color change (∆E*). The percentage of bamboo weight loss after OHT was also observed. The research results show that the brightness value (L*) of betung bamboo and andong bamboo has decreased, so that the color becomes darker as the temperature increased. The a* and b* values decreased at all temperatures and durations. In addition, the value of ∆E* increased at all temperatures with a total change showing a value > 12. The decrease in weight of betung bamboo occurred at all temperatures. This heat treatment can make the bamboo color darker and more exotic, thereby increasing the added value of the product and improving the quality of bamboo from fungi and pests due to cellulose degradation.

Abstract

Calliandra biomass pellets offer a promising alternative energy source to replace fossil fuels. Typically, these pellets are produced by directly processing the stem and bark of the calliandra (Calliandra calothyrsus) plant without separation, aiming for manufacturing efficiency. This study investigated the quality differences between calliandra biomass pellets with and without bark and varying particle sizes. Particle sizes used were 20 mesh, 40 mesh, and 60 mesh. The pellets were made using a 12 mm diameter biomass pellet mold and a manual hydraulic press with a pressure of 3 tons. Characterization involved assessing proximate analysis, calorific value, physical and mechanical properties, and Fourier Transform Infrared analysis. The test results were compared with biomass pellet standards from Indonesia, Japan, Korea, and Germany. Results indicate that bark affects several properties, with higher ash content observed in pellets with bark due to the higher mineral content in bark. Volatile matter decreases with finer particle size, influencing combustion rate. Moisture content is higher in pellets with bark, impacting combustion efficiency and smoke production. Fixed carbon values are influenced by moisture and volatile matter content. Calorific values are generally higher in pellets without bark and smaller particle sizes. Density and compressive strength increase with decreasing particle size. FTIR analysis reveals differences in functional groups between pellets with and without bark, indicating variations in chemical composition. Overall, this research provides insight into the potential of calliandra biomass pellets with bark and without bark along with particle size as a renewable energy source.

Abstract

Sengon (Falcataria moluccana) is a fast-growing species widely planted in Industrial Plantation Forests (IPF/HTI) and has high economic value. The provision of planting material must be well prepared and planned to get the appropriate nursery planting media composition. The Empty Palm Oil Bunches (EFB) biochar application improves soil's chemical and physical properties to provide nutrients for plants. This study aims to determine the effect of the application of EFB biochar on the growth of sengon roots. The experimental design was completely randomized (CRD) by applying four treatment levels and 20 repetitions. The treatments were (A) 100% soil (control), (B) 5% EFB biochar, (C) 10% EFB biochar, and (D) 15% EFB biochar. The data were then analyzed by analysis of variance to see the effect of the treatment on the observed root growth parameters, followed by the 5% Least Significant Difference (LSD) further test to determine differences between treatments. The parameters observed were root length, root volume, root wet weight, and root dry weight. The result showed that the application of EFB biochar increased the growth of sengon roots compared to the control. The greater the dose of the addition of EFB biochar given to the growing media, the more it showed a positive response in improving the growth of sengon roots. In this study, the 15% dose showed the best results compared to other treatments.
