Tanaman bawang merah merupakan salah satu jenis tanaman sayuran yangberpotensi untuk dibudidayakan di dalam polibag untuk dijadikan tanaman pengisipekarangan rumah. Penelitian bertujuan unuk mengetahui dosis pupuk KNO3 yangterbaik bagi pertumbuhan dan hasil tanaman bawang merah dalam polibag. Perlakuanyang digunakan dalam penelitian ini adalah tanpa dipupuk (0 gpolibag-1), 0,3 g polibag1, 0,6 g polibag-1, 0,9 g polibag-1, 1,2 g polibag-1, 1,5 g polibag-1, dan 1,8 g polibag-1.Hasil penelitian menunjukkan bahwa perlakuan yang digunakan memberikan pengaruhnyata pada pertumbuhan dan hasil bawang merah, terutama pada peubah diameter umbi,bobot umbi kering panen per rumpun, dan rata-rata berat kering panen umbi-1. perlakuandosis KNO30,9 g polibag-1 merupakan perlakuan terbaik untuk meningkatkanpertumbuhan dan hasil bawang merah dalam polibag.
The usage development can be increased by applying right cultivating and processing technology to grow sweet potato agroindustry that can help increasing economy value and lengthening storability. One of sweet potato potencies that can be developed in food diversification is sweet potato flour processing. The objective of this research is to study about the effect of fermentation time and various color of sweet potato to the quality of sweet potato flour. The research was done on April until June 2015 in Basic Laboratory of Agricultural College of Dharma Wacana, while the proximate test for the flour of fermented sweet potato was done in Agricultural Product Technology Laboratory of State Polytechnic Lampung. The research design used in this study was Complete Group Random Design (RAKL) arranged factorially by three repetitions. The first factor is fermentation time (t) that has 3 levels: 5 days (t 1 ), 7 days (t 2 ), and 9 days (t 3 ). The second factor is the color of sweet potato (w) that has 3 levels: white (w 1 ), yellow (w 2 ), and purple (w 3 ). The finding result shows that the effect of fermentation time and various color of sweet potato have real impact towards the flour yield, ash content, color, and flour smell as well as nutrient content of sweet potato such as water, protein, fat, crude fiber, and carbohydrate. Generally, there is no interaction except for the flour color and ash content.
Tujuan penelitian adalah menganalisis bsarnya biaya transaksi pada sistem agribisnis ubi kayu dan menganalisis pengaruh biaya transaksi terhadap pendapatan ubi kayu di Kabupaten Lampung Tengah. Tempat penelitian di Kecamatan Rumbia Kabupaten Lampung Tengah. Penelitian menggunakan metode survei kepada 141 petani ubi kayu di Kecamatan Rumbia Kabupaten Lampung Tengah yang diambil secara purposive. Analisis menggunakan metode analisis kuantitatif pada Transaction Cost (TrC); Analisis pendapatan; dan Analisis regresi linear berganda.

Tujuan penelitian adalah menganalisis pendapatan usahatani padi sawah dan menganalisis faktor-faktor sosial ekonomi yang mempengaruhi pendapatan usahatani padi sawah di masa pandemi covid-19. Analisis yang digunakan analisis pendapatan dan analisis regresi linier berganda. Teknik pengambilan sampel yaitu simple random sampling sebanyak 51 petani. Hasil penelitian yaitu pendapatan usahatani padi sawah sebesar Rp. 10,368,541.00 /ha/musim tanam dengan nilai R/C ratio sebesar 2,1 (menguntungkan). Faktor sosial ekonomi yang berpengaruh terhadap pendapatan usahatani padi sawah adalah luas lahan, harga pupuk organik, dan harga pupuk ponska, sedangkan faktor yang tidak berpengaruh nyata terhadap pendapatan usahatani padi sawah adalah tingkat pendidikan, harga pupuk kandang, harga pupuk urea, harga pupuk ZA, harga pupuk KCL, harga pestisida, jumlah anggota keluarga dan usia.
<p>Water management and technology of protection insectiside could be changes availability heavy metal in soil and plant. The objective of this research was to study the effect of water source to spray vegetables and frequency sprayer insecticide on the growth and Pb contain in vegetable. The experimental design was factorial in randomized completely block design with three replications. The result showed the effect of water source to spray vegetables and frequency insecticide spray not significant on the growth vegetables, but significant on Pb contain in vegetables. The maximum Pb (7,97 ppm) in sludge from household and twice insecticide spray.<br />Keywords: Water source, frequency insecticide, Heavy metal Pb, vegetable.</p>
