Abstract Healthy pine trees in low-density stands offer the best defense against the southern pine beetle (SPB), helping to ensure that timber resources and other benefits of forests are protected against infestations. Through the SPB prevention cost-share program, landowners of nonindustrial private forestland are able to receive a financial incentive for improving forest health by proactively undertaking forest management practices. In this study, two surveys were used to analyze this program: (1) a survey of enrollees in the SPB prevention cost-share program, and (2) a survey of forest landowners who have not participated in a cost-share program. Data are used to examine similarities and differences in the two samples (e.g., background awareness of the SPB, sources of their information about the SPB). Information obtained from cost-share program enrollees is also presented to characterize their participation and to provide an overall evaluation of the program. Data indicate that the SPB prevention cost-share program is very successful in terms of the satisfaction of its customers (i.e., the actual program participants).

Process Modification

We studied three process modifications to investigate their effects on the property and yield recovery capabilities of kraft pulping integrated with hemicellulose pre-extraction of southern pine. Loblolly pine chips were pre-extracted with hot water until the sugar extraction yield reached the targeted value of 10% and then subjected to conventional and modified kraft pulping. Modification included polysulfide pretreatment; polysulfide-sodium borohydride dual pretreatment, and polysulfide followed by polysulfide-sodium borohydride dual pretreatment two-stage pretreatments prior to kraft pulping. In the first modification, about 5% of the lost pulp yield (total 7%) caused by hemicellulose pre-extraction could be recovered with 15%-20% polysulfide pretreatment. Complete recovery (7%) was achieved with simultaneous pretreatment using 15% polysulfide and 0.5% sodium borohydride with 0.1% anthraquinone in polysulfide-sodium borohydride dual pretreatment. Two-stage pretreatment using recycled 15% polysulfide followed by simultaneous treatment of 6% polysulfide and 0.4%–0.5% sodium borohydride with 0.1% anthraquinone also achieved 100% yield recovery. Continuous recycling of 15% polysulfide employed in the two-stage process modification maintained its yield protection efficiency in a repeated recycling cycle. No significant changes in paper strength were found in handsheets prepared from the three process modifications, except for a minor reduction in tear strength.

Detail investigation of equilibrium chemical reactions in WO3–H2O system using computer program FacktSage with the aim to establish influence of temperature and quantity of water on formation of compounds of H2WO4 and WO2(OH)2 as well as concomitant them compounds, evaporation products, decomposition and dissociation, that are contained in the program data base were carried out. Calculations in the temperature range from 100 to 3000 °С were carried out. The amount moles of water added to 1 mole of WO3 was varied from 0 to 27. It is found that the obtained data by the melting and evaporation temperatures of single-phase WO3 are in good agreement with the reference data and provide additionally detailed information on the composition of the gas phase. It was shown that under heating of 1 mole single-phase WO3 up to 3000 °С the predominant oxide that exist in gaseous phase is (WO3)2. Reactions of it formation from other oxides ((WO3)3 and (WO3)4) were proposed. It was established that compound H2WO4 is stable and it is decomposed on WO3 and H2O under 121 °C. Tungsten Oxide Hydrate WO2(OH)2 first appears under 400 °С and exists up to 3000 °С. Increasing quantity of Н2О in system leads to decreasing transition temperature of WO3 into both liquid and gaseous phases. It was established that adding to 1 mole WO3 26 mole H2O maximum amount (0,9044–0,9171 mole) WO2(OH)2 under temperatures 1400–1600 °С can be obtained, wherein the melting stage of WO3 is omitted. Obtained data also allowed to state that that from 121 till 400 °С WO3–Н2O the section in the О–W–H ternary system is partially quasi-binary because under these temperatures in the system only WO3 and Н2O are present. Under higher temperatures WO3–Н2O section becomes not quasi-binary since in the reaction products WO3 with Н2O except WO3 and Н2O, there are significant amounts of WO2(OH)2, (WO3)2, (WO3)3, (WO3)4 and a small amount of atoms and other compounds.

Program Data

Farmers participation is crucial for succeeding in the implementation of agricultural insurance in Indonesia. The purposes of this research are analyzing farmers' form and level of participation and also identifying some factors affecting farmer’s participation in agricultural insurance. The research was conducted in Curug Bitung Village, District of Nanggung, Bogor Regency involving 40 respondents. Primary data includes farmers characteristics, farmers participation form and farmers participation level as program beneficiaries. The data were processed using multivariable linear regression test. The results showed that the intensity of communication, age, education level, income level and length of stay did not significantly affect the participation level of farmers whose majority were at the level of no participation. Non-compliance occurs during program implementation. The form of participation shown by farmers in the program is varied.Keywords:  agricultural insurance, internal and external factors, farmers' participation ABSTRAK Partisipasi petani menjadi hal yang penting dalam rangka menyukseskan penerapan asuransi pertanian di Indonesia. Tujuan penelitian ini adalah menganalisis bentuk dan tingkat partisipasi petani dalam asuransi pertanian serta mengidentifikasi faktor-faktor yang memengaruhi partisipasi petani dalam program asuransi pertanian. Penelitian dilakukan di Desa Curug Bitung, Kecamatan Nanggung, Kabupaten Bogor dengan melibatkan 40 responden. Data primer meliputi karakteristik petani, bentuk partisipasi petani dan tingkat partisipasi petani penerima program. Data diolah menggunakan uji regresi linier multivariable. Hasil penelitian menunjukkan intensitas komunikasi, usia, tingkat pendidikan, tingkat pendapatan dan lama tinggal tidak berpengaruh secara signifikan terhadap tingkat partisipasi petani yang  mayoritas berada pada tingkatan tidak ada partisipasi. Ketidaksesuaian banyak terjadi selama penyelenggaraan program. Adapun bentuk partisipasi yang ditunjukkan petani dalam program bervariasi.Kata kunci: asuransi pertanian, faktor internal-eksternal, partisipasi petani
