Rancang Bangun Alat Pencetak Kompos Tablet Sistem Tekan

Compost is an organic fertilizer whose basic ingredients are from weathering plant material or organic waste. However, the community has a few obstacles, namely the need for very large doses of fertilizer which often makes its use difficult. Therefore, efforts need to be made to overcome this problem, namely by making the fertilizer form into a solid form. So a tablet compost printer was made that can determine the capacity of the tool's mold with a press system. Analysis of the data used in this study is a mathematical approach using Microsoft Excel and a statistical approach using ANOVA diversity analysis and further test of Honest Significant Difference (BNJ) level 5%. The results showed that the higher the addition of hydrogel, the lower the dimension value, both weight, height and diameter of the tablet. The capacity of the mold in each treatment was carried out 3 times the average repetition of each treatment at P1 4.41 kg/hour, P2 6.10 kg/hour and P3 6.30 kg/hour the weight of the compost material affects the capacity of the mold, the heavier the material being printed, the higher the capacity of the mold

Population Structure of the Chenchu and Other South Indian Tribal Groups: Relationships between Genetic, Anthropometric, Dermatoglyphic, Geographic, and Linguistic Distances

This is the published version. Copyright 1994 Wayne State University Press.We describe the genetic structure and interrelationships of nine south Indian tribal groups (seven from Andhra Pradesh and two from the adjoining states of Tamil Nadu and Kerala) using seven polymorphic loci (ABO, MN, RH, PGM, ACP, PGD, and LDH). R matrix analysis indicates that the Andhra Pradesh tribes are clustered and that the Kadar and Irula are genetically isolated from them. This dispersion of populations has been explained by the combination of relatively high frequencies of the alleles RH D and MN M in the Kadar and the relatively high proportions of the allele PGM*2 in the Irula. The Mahaboobnagar Chenchu subgroup is isolated from other Telugu-speaking groups because of high frequencies of the PGM*1 and ACP*A alleles. The regression of mean per locus heterozygosity (//) on distance from the gene frequency centroid (r„) reveals considerable levels of external gene flow among the Lam-badi, the Yerukula, and the two Chenchu subgroups and more homogeneity in the Kolam, Koya, Yanadi, Irula, and Kadar. Mantel statistics were used to assess the relative effects of nonbiological processes (i.e., language and geography) on the morphological and genetic patterns of these subdivided populations. The significance of correlations was determined between different data sets (genetic, dermatoglyphic, anthropometric, geographic, and linguistic) at three levels involving nine, six, and five populations. Although multiple correlation analysis reveals significant combined effects of geography and language on genetics, anthropometrics, and dermato-glyphics, highly significant partial correlations suggest strong effects of geography on both anthropometry and genetics. Our analysis indicates that geographic factors have an overwhelming effect on the genetic differentiation of the south Indian tribal groups

Analisis Peluang Curah Hujan Untuk Penetapan Pola Dan Waktu Tanam Serta Pemilihan Jenis Komoditi Yang Sesuai Di Desa Masbagik Kecamatan Masbagik Kabupaten Lombok Timur

Climatic factor, such as rainfall, greatly contributes to the availability of water for crops. Farmers set a schedule and cropping patterns based on habits, such as the period of rainy month. This method is lack precision on determining crops pattern and often increasing the risk of crop failure. This study aims to determine rainfall probability in Masbagik village on growing season of 2015-2016. Research method was descriptive analytical method. Results of this research revealed that the general rainfall pattern of the study area was still following general pattern of the previous year. Rain probability that approached natural precipitation at the field of study was 50%, with the highest limits at December by 304.5 mm and the lowest at October by 37 mm, while general rainfall probability was normal. Rainy season was predicted to start at mid-November and end at early June, while dry season occurs from early May and end in early November. Recommended scenario of the first growing season for the crop is starting at mid-November until the end of February and the second growing season start at mid-March until June 2015. Moreover, planting time for growing rice can be carried out at mid-October, while from early March growing crops is more suitable. Keywords: rainfall, type of commodity, cropping pattern &nbsp

Effect Of Variation In Volume Addition Of Tofu Waste To Rice Straw On Biogas Formation

Abstract: Biogas is a renewable energy source. Biogas can be produced from agricultural waste and industrial waste. One of the alternatives to handling tofu industry waste that currently has a lot to be developed is to convert industrial waste into alternative fuel in the form of biogas. This study aims to determine the effect of the addition of tofu liquid waste on changes in temperature, pH, volume and pressure that occur during the formation of biogas. This research was conducted from July to August for 22 days. The method used in this research is the experimental method by conducting direct experiments. The design used in this study was a one-factor Completely Randomised Design (CRD), consisting of P0 with rice straw + 4 litres of water, P1 with the addition of 20% tofu liquid waste, P2 with 40%, P3 with 60%, P4 with 80% and P5 with 100%. Observation data were analysed with Analysis of Variance at the 5% level. The parameters observed in the study were temperature, pH, volume and pressure. Based on the results of the analysis that has been done, the lowest temperature was obtained in the P3 treatment at 27.39 ° C, while the highest temperature was obtained in the P2 treatment at 27.86 ° C. The lowest pH was obtained in the P5 treatment at 4.24, while the highest pH was obtained in the P1 treatment at 4.57. The lowest volume was obtained in the P1 treatment at 0.00000011513 m3, while the highest volume was obtained in the P0 treatment at 0.00000161291m3, the lowest pressure was obtained in the P3 treatment at 109.08 N/m2, while the highest pressure was obtained in the P2 treatment at 109.25 N/m2. Therefore, it can be concluded that the addition of tofu waste to rice straw does not significantly affect the formation of biogas produced
