Abstract

Daun bambu telah terbukti mampu menetralkan limbah cair hasil pertanian maupun limbah cair industry tahu berdasarkan penelitian sebelumnya yang pernah dilakukan. Akan tetapi belum diketahui senyawa kimia apa saja yang terkandung di dalam daun bambu sehingga mampu berperan sebagai penetral limbah cair. Tujuan penelitian ini adalah untuk mengidentifikasi senyawa kimia yang terkandung dalam daun bambu segar. Penelitian ini dilakukan secara eksperimental di laboratorium dengan mengamati beberapa parameter yaitu kandungan Flavonoid, Alkaloid, Saponin, dan Tanin. Hasil uji kuantitatif diperoleh berat Flavonoid untuk sampel daun bambu segar sebesar 5,5744 gram atau 5,57 % berat sampel, Alkaloid sebesar 0,1421 gram atau 2,81 % berat sampel, sedangkan hasil uji kualitatif daun bambu segar positif mengandung Saponin dan Tanin..

Abstract

The purpose of this study was to design and test the performance of drip irrigation techniques on dry land. This research method used a completely randomized design with 3 treatments, namely the faucet slope of 150 , 450, and 900 with 4 replications. In order to obtain 12 experimental sample units. Furthermore, the design results were carried out by testing the droplet discharge, uniformity coefficient, wetted soil area, and the amount of water needed during the vegetative growth of tomato plants. The test results based on the discharge value and the uniformity of drops show that the drip irrigation technique design is very good for application on dry land. Based on the discharge value, the wetted area is obtained with a wetting width of 25 cm and a depth of up to 35 cm. So that during the vegetative growth of tomato plants in treatment 150  requires 10200 ml / day of water, 12200 ml / day in treatment 450 , and 30800 ml / day in treatment 900 . Seeing the effect on tomato plant growth, it can be concluded that 150  is the best treatment to apply. on dry land.

Abstract

Faktor manusia sebagai tenaga kerja memiliki peranan penting dalam meningkatkan produktivitas beras Organik. Namun, sampai saat ini upah standar untuk pekerja pertanian belum ditentukan oleh lembaga pemerintah, sehingga bisa dikatakan bahwa peran pemerintah terhadap pekerja pertanian masih sangat kurang. Penelitian ini bertujuan untuk membuat formulasi berdasarkan analisis ekonomi ergonomika. Berdasarkan produktivitas kerja saat ini, pendekatan ekonomi ergonomika membuktikan bahwa upah yang diperoleh pekerja masih jauh dari standar UMR. Dari dua skenario optimasi yang digunakan, ditemukan bahwa perancangan penambahan mekanisasi secara selektif menggunakan mesin milik sendiri mampu memberikan upah yang optimal karena sudah memenuhi standar UMR Kabupaten Bogor.

Abstract

Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.
