Malnutrition is still one of the big problems the majority of developing countries including Indonesia. Malnutrition is the result of insufficient intake of available nutrients in the human diet. The availability of nutrients is mainly determined by the output of food produced from agricultural systems. Plants provide almost all the necessary vitamins and minerals, but due to low mineral content in staple crops, resulting in the intake becomes less and lead to malnutrition or lack of nutrients. Unfortunately, as a result of population pressure, a lot of the current global food system does not provide enough micronutrients to ensure adequate micronutrient intake for everyone. This has resulted in an increase in the prevalence of micro-nutrient deficiencies (for example, iron deficiency, vitamin A deficiency, and iodine), which now afflicts many poor women resources, infants and children in developing countries. To get a balanced nutrition and adequate then improve the quality of agriculture as a food ingredient indispensable. Various attempts to overcome nutritional deficiencies especially regarding micro nutrient deficiencies, such as supplementation, food fortification and diversification of the food has a lot to do, but did not provide maximum results. Another alternative approach to address the problem of shortage of micronutrients is biofortification, genetic biofortification or agronomic biofortification. This approach emerged due to health and human well-being depends entirely on the plants, either directly or indirectly.

Rice production in Indonesia can not cover the national needs. The low productivity caused by the decline in soil fertility. One way to increase the phosphorus content in the soil is to provide natural phosphate fertilizer and Azolla inoculum. This study was conducted to determine the proper dose of Azolla inoculum and rock phosphate to increase the availability of phosphate and increase the yield of rice plants on land Alfisol. This study uses the two-factor factorial CRD comparative treatment of manure and fertilizer N, P, K. Analysis of the observed data using analysis of variance at 5% level and if there is a significant difference effect followed by DMRT 5% level to compare between treatments. The results showed that treatment of Azolla inoculum and phosphate can increase the availability of phosphate in the Alfisol soil and can increase rice yield. On the parameters available P showed the highest results in the treatment of Azolla 2.5 tons / ha without natural phosphate and Azolla 5 tons / ha of natural phosphate 350 kg / ha which is 10.81 ppm. In addition, administration of Azolla inoculum and phosphate levels give rise to CEC, organic matter, total N in the soil and soil pH.

Penelitian ini bertujuan untuk mengetahui kadar kholesterol daging ayam broiler yang dipelihara dengan cekaman luas lantai dan suplementasi vitamin C di dalam air minum. Penelitian ini menggunakan rancangan acak lengkap pola faktorial 3x3, dengan faktor pertama perlakuan luas lantai (A) yaitu tida tingkatan luas lantai (A1=0,10 m2/ekor, A2=0,80 m2/ekor, A3=0,60 km2/ekor) dan faktor kedua level vitamin C di dalam air minum (B) yaitu tiga level dosis vitamin C (B1=0 ppm, B2=600 ppm dan B3=1200 ppm). Sehingga terdapat sembilan kombinasi perlakuan setiap perlakuan menggunakan tiga ulangan. Seratus tiga puluh lima ekor ayam digunakan dalam penelitian ini dibagi ke dalam sembilan kombinasi perlakuan, dengan tiga ulangan masing-masing berisi lima ekor ayam broiler jantan strain Hubbard berumur dua minggu. Pemeliharaan ayam dilaksanakan sesuai dengan perlakuan, setelah ayam berumur enam minggu dilakukan pengambilan sampel secara acak, dari setiap ulangan dipotong dua ekor ayam broiler. Peubah yang diukur adalah persentase bobot karkas terhadap bobot hidup, kadar protein, kadar lemak dan kadar kholesterol daging dada. Data yang diperoleh dianalisis variansi sesuai dengan rancangan yang digunakan, apaabila terdapat pengaruh yang nyata dilanjutkan dengan uji jaraak berganda Duncan (Duncan Multiple Range Test).Hasil anaisis data penelitian menujukkan bahwa perlakuan tiga tingkat luas lantai tidak menunjukkan pengaruh yang nyata terhadap persentase bobot karkas, kadar protein, kadar lemak dan kadar kholesterol daging ayam broiler. Sedangkan pemberian vitamin C pada air minum tidak memberikan peningkatan dari semua peubah yang diukutr. Interaksi dari kedua perlakuan tidak menunjukkan pengaruh yang nyata terhadap semua peubah yang diukur. Pemeliharaan ayam broiler dapat dilakukan dengan menggunakan luas lantai 0,06 m2 per ekor dengan suplementasi vitamin C dalam air minum tanpa menurunkan persentase bobot karkas dan kadar protein dagingnya. Kadar lemak dan kadar kholesterol daging ada kecenderungan menurun dengan cekaman luas lantai yang relatif sempit tersebut.

Planting drought-resistance plants in terms of agronomy, such as induction of plant tolerance using calcium is assumed to be able to solve the climate anomaly problem. Calcium is known as an element that plays an essential role in determining the response of plant resistance to drought through biochemical activity. This study aimed to determine the role of calcium in changing photosynthesis activity in order to increase the resistance to drought stress. The treatment was arranged in factorial of 3 x 4 in a split plot Randomized Complete Block Design replicated three times. The first factor was the dose of calcium application consisted of 0 (control/without calcium), 0.04, 0.08 and 0.12 g. The second factor was the intensity of drought stress, which referred to the Fraction of Transpirable Soil Water method consisted of 1 (control/field capacity), 0.35 (moderate drought) and 0.15 (severe drought). The measurement data of stomatal aperture, Abscisic Acid (ABA) content, chlorophyll content, carotenoid content, proline content, nitrate reductase activity and photosynthesis rate that fulfill the assumption of homogeneity and normality were analyzed using variance at 95% accuracy and continued using DMRT. Moreover, regression analysis were determined of relationship between the treatment and parameters. The results revealed that drought resulted in a decline in leaf water potential and stomatal aperture. The effects of calcium on chlorophyll and carotenoid under drought stress could not be explained in this study. However, the application of calcium has a significant effect on decreased ABA, increased proline and nitrate reductase activity resulting in an increase in the photosynthetic rate of oil palm seeds in drought stress.
