This study aims to analyze the revenues, the value added, efficiency, and break even point of traditional herbal medicine agroindustry. The results of this study indicate that the traditional herbal medicine agroindustries in the procurement of primary ingredient and supplementary ingredients did not have a problem. Traditional herbal medicine agroindustries used the traditional technologies and processing was manually. The average gross revenues as much as Rp3,925,480.00 /month or as much as Rp111,614.44/kg of primary ingredient. The average net income Rp1,005,239.79/month or as much as Rp28,582.31/kg of primary ingredient.The average of the families employment income Rp2,882,017.57/ month or as much as Rp81.945,34 /kg of primary ingredient. The average of value added of the traditional herbal medicine agroindustries Rp2,904,689.87/month or as much as Rp82,589.99/kg of primary ingredient. While the traditional herbal medicine agroindustries was efficient at the RCR average of 1.34, meaning that the traditional herbal medicien agroindustries effort is feasible and efficient to be developed
Viscosities of the Gay-Berne nematic liquid crystal
We present molecular dynamics simulation measurements of the viscosities of
the Gay-Berne phenomenological model of liquid crystals in the nematic and
isotropic phases. The temperature dependence of the rotational and shear
viscosities, including the nonmonotonic behavior of one shear viscosity are in
good agreement with experimental data. The bulk viscosities are significantly
larger than the shear viscosities, again in agreement with experiment.Comment: 11 pages, 4 Postscript figures, Revte
Respons Pertumbuhan Bibit Pinang (Areca catechu L.) Terhadap Aplikasi Limbah Solid Kelapa Sawit
Penelitian ini bertujuan Untuk melihat pengaruh pemberian dosis limbah solid kelapa sawit terhadap pertumbuhan bibit pinang dan untuk mendapatkan dosis limbah solid kelapa sawit yang memberikan pertumbuhan bibit pinang terbaik. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Jambi yang terletak di Desa Mendalo Darat Kecamatan Jambi Luar Kota Kabupaten Muaro Jambi dengan ketinggian tempat ± 35 meter dpl dari bulan Maret sampai Juni 2021. Rancangan yang digunakan yaitu Rancangan Acak Kelompok (RAK) yang dikelompokkan berdasarkan tinggi bibit dengan 6 taraf perlakuan dosis limbah solid kelapa sawit (d) yaitu: Tanpa perlakuaan/Kontrol (d0), 100 g/Tanaman (d1), 150 g/Tanaman (d2), 200 g /Tanaman (d3), 250 g/Tanaman (d4), 300 g/Tanaman (d5). Variabel yang diamati yaitu Pertambahan tinggi bibit, pertambahan diameter batang, jumlah daun, berat kering tajuk, berat kering akar, dan rasio tajuk akar bibit pinang. Hasil penelitian menunjukkan bahwa Pemberian limbah solid kelapa sawit berpengaruh nyata terhadap pertumbuhan bibit pinang, yaitu pada variabel pertambahan tinggi bibit, pertambahan diameter batang, berat kering tajuk, dan rasio tajuk akar bibit pinang. Namun, tidak berpengaruh nyata terhadap jumlah daun dan berat kering akar bibit pinang. Dosis limbah solid kelapa sawit yang memberikan pertumbuhan bibit pinang terbaik dalam penelitian ini yaitu 100 g/tanaman
Respons Pertumbuhan Bibit Kopi Liberika (Coffea liberic W. Bull Ex Hiern) Terhadap Aplikasi Pupuk Kandang Sapi Di Polybag
Fluktuasi produksi dan produktivitas kopi Liberika di Provinsi Jambi disebabkan oleh beberapa hal salah satunya adalah umur tanaman kopi Liberika yang sudah tua mencapai kurang lebih 40 - 50 tahun sedangkan umur ekonomis tanaman kopi Liberika hanya berkisar 30 tahun. Oleh karena itu perlu upaya peremajaan tanaman kopi menggunakan bibit unggul. Untuk menyediakan bibit yang unggul diperlukan masukan yang dapat mempengaruhi pertumbuhan bibit dan satu diantara masukan tersebut adalah pemberikan pupuk organik. Penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk kandang sapi terhadap pertumbuhan bibit kopi Liberika di polybag dan memperoleh dosis pupuk kandang sapi yang memberikan pertumbuhan terbaik pada bibit kopi Liberika di polybag. Penelitian dilaksanakan di Teaching and Research Farm Fakultas Pertanian Universitas Jambi, Kampus Unja Mendalo. Waktu pelaksanakan selama kurang lebih tiga bulan, yaitu pada bulan Februari sampai bulan Mei 2020. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK), dengan 1 faktor yaitu pupuk kandang sapi (p) yang terdiri dari 5 perlakuan yaitu 0 g/tanaman, 160 g/tanaman, 190 g/tanaman, 220 g/tanaman dan 250 g/tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang sapi dosis 0 g/tanaman sampai 250 g/tanaman pada bibit kopi Liberika umur 5 – 8 bulan belum mampu meningkatkan pertambahan tinggi tanaman, pertambahan diameter batang, pertambahan jumlah daun, umur muncul tunas, bobot kering tajuk, bobot kering akar sampai rasio tajuk akar. Tidak terdapat dosis pupuk kandang sapi yang mampu meningkatkan pertumbuhan bibit kopi Liberika di polybag
Anisotropic Pair Correlations and Structure Factors of Confined Hard-Sphere Fluids: An Experimental and Theoretical Study
We address the fundamental question: how are pair correlations and structure factors of hard-sphere fluids affected by confinement between hard planar walls at close distance? For this purpose, we combine x-ray scattering from colloid-filled nanofluidic channel arrays and first-principles inhomogeneous liquid-state theory within the anisotropic Percus-Yevick approximation. The experimental and theoretical data are in remarkable agreement at the pair-correlation level, providing the first quantitative experimental verification of the theoretically predicted confinement-induced anisotropy of the pair-correlation functions for the fluid. The description of confined fluids at this level provides, in the general case, important insights into the mechanisms of particle-particle interactions in dense fluids under confinement
Lyapunov Exponent Pairing for a Thermostatted Hard-Sphere Gas under Shear in the Thermodynamic Limit
We demonstrate why for a sheared gas of hard spheres, described by the SLLOD
equations with an iso-kinetic Gaussian thermostat in between collisions,
deviations of the conjugate pairing rule for the Lyapunov spectrum are to be
expected, employing a previous result that for a large number of particles ,
the iso-kinetic Gaussian thermostat is equivalent to a constant friction
thermostat, up to fluctuations. We also show that these deviations
are at most of the order of the fourth power in the shear rate.Comment: 4 pages, to appear in Rapid Comm., Phys. Rev.
Breaking conjugate pairing in thermostatted billiards by magnetic field
We demonstrate that in the thermostatted three-dimensional Lorentz gas the
symmetry of the Lyapunov spectrum can be broken by adding to the system an
external magnetic field not perpendicular to the electric field. For
perpendicular field vectors, there is a Hamiltonian reformulation of the
dynamics and the conjugate pairing rule still holds. This indicates that
symmetric Lyapunov spectra has nothing to do with time reversal symmetry or
reversibility; instead, it seems to be related to the existence of a
Hamiltonian connection.Comment: 4 pages, 3 figure
The Impact of Building Information Modelling (BIM) Strategies in Energy Sustainability Elements to Sustainable Campus Using PLS-SEM Approach
This paper establishes a structural relationship between BIM strategies in eleven (11) energy sustainability elements divided into management and technical aspects that impact a sustainable campus. The work established thirteen (13) benchmarks for independent variables and one (1) dependent variable. The exploratory research design used in this study led to the structural model development being the central focus of the study. A judgmental sampling technique was used to distribute a questionnaire survey among local engineers, assistant engineers, and technicians in Kota Kinabalu, Sabah, Malaysia. The research population survey employed 78 returned questionnaires. The analysis used Partial Least Squares Structural Equation Modelling (PLS-SEM) to test the hypotheses. The result indicate that the management and technical aspects of Energy Sustainability Elements (ESE) have a significant impact on sustainable campus with path coefficients of 2.447 and 5.032, respectively. The findings have revealed that hypothesis 1 and hypothesis 2 were all positive and significant at the 0.05 level, indicating that these two hypotheses are valid and supported. This study provides valuable information and insights for Malaysian universities to achieve a sustainable campus by adopting building information modelling (BIM) strategies in the context of energy efficiency
