Abstract

Applying organic matter to the soil surface is an effective effort to increase soil resilience in the Palu valley, which is classified as low. This study aimed to determine: 1) the effect of several doses of compost on the physico-chemical properties of the soil, 2) the correlation between the percentage of organic carbon and total nitrogen in the soil to several physico-chemical properties of the soil. The research was based on a randomized block design in a greenhouse of the Faculty of Agriculture, Tadulako University, Palu. Compost uses raw materials for plantain stems (Musa textilia) and leaves of Gamal (Gliricidia sepium). The compost doses used in the experiment consisted of 0%, 1%, 2%, 3%, 4%, and 5% of the weight of air-dry soil, respectively. The treatment was repeated three times. The results showed that compost application significantly affected soil content weight, total porosity, saturated hydraulic conductivity, field capacity moisture content, percentage of organic carbon, total nitrogen, and cation exchange capacity. The correlation test results showed a powerful relationship between the percentage of organic carbon or total soil nitrogen to other soil physico-chemical properties observed in the experiment.

Abstract

The primary commodity consumed by people is reflected in the highest expenditure to fulfill it within a specific period, the dominance of expenditure in all consumption expenditures indicates the importance of commodities in all households' consumption. This study aims to identify the dominant consumption patterns of food commodities using descriptive analysis of 6,178 households obtained through national secondary data from the 2017 national socio-economic survey (Susenas). Several commodities categorized by largest to smallest expenditure are the basis for determining the largest consumption expenditure as essential commodities. Based on the ranking of consumption expenditures, the three most prominent consumption groups were identified, namely: (1) rice, (2) rice with assortment of side dishes, and (3) fish. Rice, detected through 4,771 households, is the largest consumption commodity, and expenditure on this commodity increases in line with the rise in income, reflected in the mean value of expenditure which is higher in the increasing income group. The expenditure of rice with assortment of side dishes was detected through 3,150 households and had the same tendency as rice, particularly increased expenditure in the higher income groups. Fish consumption expenditure was detected through 3,488 households following the conditions for the two previous commodities, and expenditures increased with higher income. The increased expenditure on the consumption of essential commodities by income groups demonstrates that the tendency to consume is in accordance with Keynes's relationship between consumption and revenue. The higher the income, the greater the consumption expenditure. However, to a certain extent, the specific relationship is that the proportion of increased consumption expenditure decreases with higher income. Based on the elasticity coefficient, it was found that three essential commodities were normal goods. However, the level of consumption sensitivity to rice and fish income was higher than for processed food. In contrast to elasticity, the tendency to consume processed food is higher; the share of the increase in revenue is used to increase consumption of processed food, compared to adding rice and fish. This finding acts as provisional evidence that food consumption has undergone a fundamental change to become more consumptive.

Abstract

Purple sweet potato is a source of anthocyanins that function as antioxidants, antimutagenic, and anti-carcinogenic so that it has the potential to be processed into various functional food products. The stability of anthocyanin levels in the product is greatly influenced by temperature during processing, where the use of high temperatures will damage and reduce anthocyanin levels. This research was conducted to determine the effect of processing and combination of raw materials on anthocyanin levels and antioxidant activity of tortilla products made from a combination of purple sweet potato (Ipomoea batatas L) and cassava. The research design used a completely randomized design, with the object of research being tortillas made from purple sweet potato obtained from Palolo District, Sigi Regency, Central Sulawesi Province, combined with cassava obtained from the local market in Palu City, Central Sulawesi Province. The results showed that the anthocyanin levels of tortilla products varied from 5% (P1) to 19.63% (P5). There was a very significant decrease in anthocyanin levels around 68.26 - 91.91%. The amount of antioxidant activity was measured by IC50, wherefrom the research it was known that the IC50 value of tortilla products ranged from 242.68 to 155.66 µg / ml which indicated that the antioxidant activity of tortilla products was weak and even almost inactive. Based on the results of the study, it is indicated that the processing of purple sweet potatoes into tortillas is not appropriate because the processing is predominantly using high temperatures so that it can damage the anthocyanin content and reduce antioxidant activity.
