Abstract
As noted in the literature review, the effect of H2O2 on a living cell as an oxidative stress agent is in many ways similar to the effect of X-ray radiation. In living cells, both H2O2 and X-ray irradiation cause oxidative stress and induce the same system of antioxidant anti-stress response. In addition, small doses of radiation can carry certain signaling functions in relation to the activity of microorganisms. In this regard, at this stage of research, it was interesting to find out whether exposure at a dose of 400 Gy and 800 Gy of X-ray radiation could be favourable for the growth of microorganisms with the introduction of extracts of medicinal plants and under which conditions.

Abstract
Drought stress threatens potato production by reducing tuber yield. To maintain the supply of potatoes, potato cultivars that are able to adapt and tolerate to water deficit conditions are needed. The aim of this study was to obtain potato genotypes with high tolerance in the early in-vitro selection by Polyethylene Glycol (PEG) treatment. Fifty-one potato genotypes were used in this in-vitro evaluation, cultured in the MS medium which treated by four level of PEG 6000 to induce the drought stress, namely 0, 30, and 60 g.L-1. The study revealed that in-vitro plants respond to PEG-induced drought stress by reducing their growth and vigour. The decreasing of plantlet vigour and leaves size also observed. At the end of observation, five genotypes performed good vigour at the 60 g.L-1 of PEG 6000, namely CIP 394613.139 × 5.13:1.1, ATL × 3.11:1.7, 2.13 × ATL:1.12.10.3, ATL × 3.11:3.6, and ATL × 3.11:8.14. Those genotypes were indicated tolerant to drought stress and need to be followed up with further evaluation in the green house environment to see the ability of tuberization under controlled water deficit condition.

Abstract
Sweet potato is a functional food that has potential to be cultivated in paddy fields after rice harvesting. Rice straw has the potential to become waste that can pollute the environment. Efforts that can be made to overcome these problems are to use rice straw as a raw material for making compost and apply it to sweet potatoes. This study aims to determine the effect of growth and production of local sweet potato genotypes with rice straw compost. The design used in this study was a Randomized Block Design with two factors, namely local genotypes (Cengkeh Turi yellow tubers, Cengkeh Turi orange tubers, and Tanah Seribu orange tubers) and dose of rice straw compost (0, 5, 10, 15 tons/ha). The results of this study showed that the local genotypes were significantly different in vine length, tuber length and average tuber weight. The application of straw compost at various doses significantly affected the increase in vine length, tuber length and average tuber weight. The interaction of local sweet potato genotypes and rice straw compost increased tuber length. The best growth and production was obtained from the local sweet potato genotype Tanah Seribu orange tubers with 10 tons/ha of rice straw compost.

Published: July 2022

Abstract
Activities in the agricultural sector are always faced with risk and uncertainty. The problem of uncertainty is also experienced by vegetable farmers in Marelan District. Generally, farmers in Marelan cultivate long beans, spinach, and mustard. One alternative that can be done by farmers to minimize the impact of risk is by doing diversification. Moreover, diversification also supports the sustainability of agriculture. Diversification farming can be done by combining two or more crops in one area of cultivated land. This combination is also referred to as a crop farming portfolio. The optimal portfolio selection will be affected by the return and risk of the portfolio and farmers’ risk preferences. The result showed that the optimal portfolio in neutral preference is the portfolio II, spinach farming in monoculture. When risk preference changes from risk averse to very risk averse, the optimal portfolio is portfolio VI, the combination of spinach and mustard. The results of this research can be used by farmers as a reference in selecting the best portfolio and a reference for the government in making policies related to vegetable farming so that vegetable farming in the Marelan district could become sustainable farming and have a good impact to the environment.
