Abstract

The aim of this study was to determine the Alellopathy Potential contained in Imperata cylindrica extract as a Bio-herbicide. The research was conducted at the Experimental Garden of the Faculty of Agriculture; Wijaya Kusuma Surabaya University. This research method used completely randomized design (CRD); with 4 treatments and 6 replications. The treatments are (A0): Control; A1 : extract concentration ( 250 g/L) ; A2 : 500g/L ; (A3); 750 g / L. Observational data were analyzed using Analysis of Variant (ANOVA), then tested with 5% BNT. The results showed allelopathy contained in the extract of Imperata cylindrica L. can suppress weed seed germination up to 94.67 %; and has a negative effect on the initial growth of spiny spinach (Amaranthus spinosus L) seedling sprouts. With treatment A2 and A3 ; All weed seeds that were able to germinate grew abnormally (100%). Imperata cylindica extract has the potential to be used as a bio-herbicide (natural herbicide) to suppress the early growth of weed seeds on spinach spines.

Abstract

The principle of food sovereignty is a democratized system of food, transparent, environment-based, local products and markets as the main pillars in achieving sustainable food security. Food sovereignty makes a very real contribution to overcoming food insecurity in areas where there are frequent extreme climates, crop failures, dependence on imported food, and encouraging the provision of long-term healthy food (sustainable) that is accessible to all communities (equitable) and encourages local food production and consumption (local wisdom). Food sovereignty seeks to improve the quality of life of farmers and rural communities. Strategies to build food sovereignty can be through (a) Utilization of biodiversity as a sustainable source of food through diversification of local food, (b) Improvement of agricultural cultivation and quality of food production through research and innovation produced by BRIN, (c) Consistency in the implementation of protection of productive agricultural lands from land use conversion, (d) Support for monetary, fiscal policies and access to finance for farmers, fishermen, and other food producers, (e) Improving the technology of processing/downstreaming food commodities in a productive, efficient, competitive, and sustainable manner, (f) Development of infrastructure and food production facilities appropriately and integrated, (g) Synergy of food development policies between the central and regional governments, and (h) Implementation of import duties on food imports to protect domestic food commodities and products.

Abstract

The study aims to inventory and analyze GHG Carbon Dioxide (CO2) emissions to support RAD in the mitigation and adaptation of PI Situbondo Regency. It is hoped that the research output can become input for  Regional Governments in implementative designing mitigation and adaptation actions. The scope of the research in the Situbondo Regency area was six months. The analysis method uses a remote sensing system through exploration of Sentinel-5P satellite data for GHG Carbon Dioxide (CO2) gas numerical spatial data on cloud-based digital platform Java script Google Earth Engine (GEE) and Google Colaboratory Research (GColab) 2023, image digitization and outlasting in QGIS software. Research data is remote sensing data access to the Carbon Dioxide gas datasets Sentinel_5P OFFL_CO Offline, and MOD 11A1.061_Terra LST, and EDG 1km. The results show that the highest CO density variable in 2017 was 116 – 239 g/m2, then decreased to 109 – 227 g/m2 in 2019, and to 66 – 180 g/m2 in 2021. The highest range of LST variables in 2017al was 19 – 39 0 C, then increased to 21 – 40 0 C  in 2019, and in 2021 decreased again to 18 – 38 0 C. Regional variables The highest LST distribution in 2017 and 2019 was relatively the same in each sub-district, namely Situbondo, Panarukan, Panji, Kapongan and Jangkar. CO and LST density variables in 2021 are not correlated, r = 0.1 - 0.3

Abstract

The effect of seed tuber weight on the growth and production of potatoes (Solanum tuberosum L.) is intended to determine the efficiency of using tubers as seed material in potato cultivation. The single factor experiment was carried out using a randomized block design (RAK) consisting of 8 treatments, namely treatment A (Granolla variety with tuber weight 28 – 30 g), B (Granolla variety with tuber weight 31 – 45 g), C (Granolla variety with tuber weight 46 – 60 g), D HPS variety with tuber weight 31 – 45 g (Granolla variety with tuber weight 61 – 80 g), E (HPS variety with tuber weight 28 – 30 g), F (HPS variety with tuber weight 31 – 45 g), G (HPS variety with tuber weight 46 – 60 g), and H treatment (HPS variety with tuber weight 61 – 80 g). Each treatment was repeated four times. The results showed that the results were better for tubers weighing 46 - 60 g than tubers weighing 28 - 45 g, and the results were the same compared to tubers weighing 61 - 80 g, both for the HPS variety and the granolla variety. In developing potato cultivation, it is necessary to pay attention to the availability of quality seeds, the weight of the seed tubers and varieties that are suitable for the land environment. By increasing the production of quality tuber seeds, it is hoped that it can contribute to increasing productivity and potato production
