Wood vinegar is a brown liquid by-product obtained from the carbonization process. Wood vinegar could limit the usage of wood vinegar as pesticide in acidic soil because of its acidity. This study aimed to determine the main organic and inorganic components in neutralized durian wood vinegar. Wood vinegar was made by pyrolisis of durian wood in the absence of oxygen with a temperature of 350, 450, and 550 °C for 2 hours. Before being analyzed, wood vinegar was neutralized with NaOH 25% to formulate the new friendly pesticide in an agricultural field. Characterization for acidity was by pH meter; organic compounds were using GC-MS; inorganic compounds were using AAS. The result showed that both neutralized wood vinegar and acidic wood vinegar indicated groups of organic acids, phenol and carbonyl compounds, which were suspected as pesticides. The predominant component in acidic wood vinegar was guaiacol, while in neutralized wood vinegar was pyrocatechol. Both acidic and neutralized wood vinegar indicatively contained main inorganic elements such as sodium, calcium, potassium, magnesium, iron and zinc that could serve as a natural pesticide. Based on the analysis result of inorganic elements, there were significant differences between acidic and neutralized wood vinegar except for Ca.
Proses Pyrolisis biomasa menghasilkan Asap cair dan Biochar. Hasil analisa terhadap proses produksi Asap Cair dan Biochar melalui Proses Pyrolisis memiliki profitabilitas yang tinggi sehingga usaha ini mempunyai prospek yang menjanjikan dan pasar sangat terbuka lebar. Asap Cair yang telah ada dipasar, diproduksi dari bahan baku tempurung kelapa dengan penggunaan terbanyak untuk koagulan karet dan sedikit sekali untuk keperluan pangan. Sedang produk Biochar belum terdapat satupun perusahaan di Indonesia yang secara spesifik menjualnya atau memasarkannya. Tujuan yang ingin dicapai adalah memproduksi Asap Cair dan Biochar menggunakan teknologi pyrolisis dengan bahan baku utama Sekam Padi dan bahan baku pengganti berupa tongkol jagung, jerami padi, jerami jagung, limbah bambu, gergajian kayu dan limbah biomassa lainnya. Methode yang akan dipakai meliputi Produk Asap Cair yang dihasilkan dibagi dalam 3 (tiga) grade yang disesuaikan dengan karakteristik dan sifat-sifat fungsional dari senyawa penyusunnya. Keunggulan yang dikembangkan adalah tidak memilih Asap Cair sebagai koagulan karet tetapi sebagai pengawet makanan dan insektisida. Sedang Biochar dijual langsung sebagai bahan perbaikan tanah pertanian terdegradasi dan untuk energi alternatif dalam bentuk bio-bricket.
Kecamatan Nawangan adalah salah satu wilayah di Kabupaten Pacitan yang sebagian besar merupakan wilayah pertanian dan bukan daerah pantai, mempunyai luas wilayah 124,06 km2 terdiri dari 9 desa, 130 RW dan 428 RT. Jumlah Penduduk 52.144 orang. Dua dari sembilan desa yang ada yaitu Desa Sempu dan Desa Jetis Lor merupakan wilayah pertanian padi yang pada tahun 2010 produksi padi di Desa Sempu mencapai 1.441,89 ton (GKG) dengan rata-rata produksi 55,03 Kw/Ha, sedang Desa Jetis Lor 1443,4 ton (GKG), rata-rata produksi 57,05 Kw/Ha. Namun, kondisi ini belum bisa memberikan dampak positif pada petani khususnya pendapatan yang diperoleh dari hasil bertani dan buruh tani. Oleh karena itu, Ipteks bagi Wilayah (IbW) Kecamatan Nawangan telah melakukan inovasi teknologi berbasis limbah perpadian yaitu sekam padi menjadi produk - produk yang mempunyai nilai ekonomis dengan menggunakan teknologi tanpa limbah yaitu Teknologi Pyrolisis Berdasarkan kondisi eksisting wilayah, ada dua Aspek yang dikembangkan dalam kegiatan ini yaitu Aspek Ketahanan Pangan dan Aspek Kemandirian Energi. Dua aspek ini dapat dikerjakan dan dapat bersinergi dengan kegiatan lainnya melalui pemberdayaan masyarakat. Kegiatan ini telah dapat menumbuh-kembangkan usaha ekonomi produktif, munculnya kepedulian memperbaiki sarana prasarana fisik lingkungan desa dan meningkatkan partisipasi dalam mengorganisasi diri dan menemu-kenali kebutuhan dalam perencanaan dan pembangunan Kata kunci : Pertanian padi, Ipteks bagi Wilayah, pyrolisis.
Soybeans and meat are the most strategic food commodities and are very risky if it is fully entrusted to the mechanism of the free market. The point is, soy and meat commodities have a very central role in national food policy channels. One of the agricultural ministry targets for 2010 - 2014 is to increase food diversification, especially to reduce rice and wheat consumption. During 2010 - 2014, rice consumption is targeted to fall by 1.5% per year and balanced by increasing in consumption of tubers, animal foods, fruits and vegetables. On the other side, it is also strived to achieve a diverse, nutritious, balanced and safe food consumption pattern as reflected by the increase of Expected Food Pattern (PPH) scores from 86.4 in 2010 to 93.3 in 2014. This study aimed to determine the characteristics of the community in taking decision to buy food products from both tofu and meat sources and to analyze the key factors of consumer’s willingness to buy tofu and meat by using multiple linear regression methods. The results of the study showedthat the characteristics of respondents in the research that affected the gender of respondents were women because married women were the decision makers in terms of household needs. The factors that affected the willingness of consumers to pay tofu were: taste, price and size. Meanwhile, thefactors that affected consumers' willingness to pay for meat were price and shape.
