Analysis of factors affecting organic rice exports in Indonesia

Qorimah Handari Harahap — 2024-01-02

The market opportunities from organic farming which are getting bigger globally are being utilized by farmers in various regions in Indonesia and have succeeded in cultivating organic rice and have quite wide market coverage even abroad. This research aims to determine the factors that influence the volume of organic rice exports in Indonesia. The results of multiple linear regression prove that the domestic price of organic rice, the international price of organic rice and the dollar exchange rate against the rupiah influence the volume of organic rice exports in Indonesia. The price of organic rice, both domestic and international, has a negative effect on organic rice exports. Meanwhile, the dollar exchange rate against the rupiah has a positive effect on organic rice exports. The policy implications based on the research results are (a) Seeing the research results showing that the price of domestic organic rice has a negative and significant effect on organic rice exports, the government must maintain prices (inflation), especially the price of domestic organic rice. (b) When the rupiah depreciates, organic rice exports will increase, but exchange rate stability must be maintained by the government. So the increase in organic rice exports is the result of increased rice production, not just the exchange rate.

Tri Suryanti — 2024-07-19

The waste problem is a problem for all parties because the negative impacts caused by waste are very diverse. Increase in waste volume caused by community activities. Research related to waste management that utilizes information technology and data mining is currently still widely open. It is hoped that the use of this technology can support decision-making in sustainable development. As a complement to this research, it also reveals that the public's perception of waste management regarding waste volume is a negative perception, which shows that the more people know about information about waste management, it has an impact on reducing waste volume. On the other hand, the positive perception shows that there is less Information about waste management has an impact on increasing the volume of waste. Both the results of the data mining process and public perception are in agreement. It is hoped that this suitability can be used as support for decision-making regarding waste management to maintain the sustainability of abiotic, biotic and cultural factors

Rahman Rahman — 2024-07-20

One of the efforts to mitigate climate change is the preservation of mangrove ecosystems because of their function as carbon storage and absorbers. The coast of Karawang Regency is a potential area for mangrove ecosystems, but information on existing carbon stocks and sequestration is not yet known, let alone the contribution of mangrove rejuvenation, including from rehabilitation seedlings. The study results show that the total carbon stock on the coast of Karawang Regency ranges from 13.75 – 56.89 MgC ha–1 or 5,799.88 – 24,003.58 MgC. This value is obtained from the contribution of three main species, namely A. marina of 4.38 – 15.38 MgC ha^–1, R. apiculata of 5.80 – 24.63 MgC ha^–1, and R. mucronata of 3.57 – 16.88 MgC ha^–1. The carbon sequestration value (CO₂-equivalent) on the coast of Karawang Regency ranges from 50.40 – 208.58 MgCO₂-eq ha^–1 or an overall of 21,266.23 – 88,013.14 MgCO2-eq. This value was obtained from the contribution of three main species, namely A. marina of 16.07 – 56.41 MgCO₂-eq ha^–1, R. apiculata of 21.25 – 90.29 MgCO₂-eq ha^–1, and R. mucronata of 13.08 – 61.88 MgCO₂-eq ha^–1. The total contribution value of stock and carbon sequestration from mangrove rejuvenation in the simulation up to 10 years of diameter growth reached 24.58 MgC year^–1 and 90.14 MgCO₂-eq year^–1. These values are an accumulation of three categories of youth, namely the existing sapling category (7.86 MgC year^–1 and 28.82 MgCO₂-eq year^–1), the existing seedling category (4.72 MgC year^–1 and 17.32 MgCO₂-eq year^–1), and the seedling category (3.64 MgC year^–1 and 13.33 MgCO₂-eq year^–1).

Setyo Ari Wibowo — 2024-08-26

River borders are green belts that should be free from permanent, non-permanent or semi-permanent buildings. However, people still use many river borders to build houses. Gandul River is one of the rivers with borderland use that violates regulations. This research aims to analyze the quality of polluting elements and SWOT analysis for strategies for controlling pollution. The research was carried out using a mixed methods approach in the form of quantitative and descriptive. Descriptive research analyzing water quality as an abiotic element was assessed using water quality parameters (temperature, TDS, TSS, pH, total coliform, and DO) and a qualitative culture analysis will be carried out using SWOT (Strengths, Weaknesses, Opportunities, Threats) on 60 respondents who live in Gandul River border as the main respondent. The polluting elements in the Gandul River are coliforms that reached >16,000 during 2021-2023. Strategies in efforts to control buildings on the Gandul River border include firm action to implement government and regional regulations, providing education, and assisting the community with relocation efforts. Land use on the Gan-dul River border causes an increase in the total coliform value so efforts are needed to relocate.

The Wastewater-contaminated treatment with heavy metals by using a sustainable green nanomaterial

Dhurgham Ali A Al- Sultany — 2024-09-07

The current research included treating wastewater with sustainable nanotechnology to remove some trace elements (arsenic, copper, baron, lead, and chromium) by using a nanomaterial extracted from potato plant waste in a sustainable, green, environmentally friendly way, with two different additions, the first adding 0.5 grams and the second adding 1 gram of nanocellulose. For two different periods (6 hours and 12 hours) for both quantities of nanocellulose. The results showed that nanocellulose has a great ability to remove the studied elements from wastewater after comparing their original concentrations that were in the water before treatment with nanocellulose. The results showed that increasing the amount of nanocellulose and increasing the time led to an increase in the removal rate, and this was clear from the results of the statistical analysis, which showed the presence of a positive significant correlation between the rate of removal of trace elements from waste water with increasing the amount of nanocellulose and increasing the time. When comparing the removal rates of the studied elements from wastewater with the PH values, it was found that the pH is the control of these rates, as the highest removal rates were at the neutral or close to acidic level, the pH between 5.5 and 7.5, and when the pH tends towards basicity (8 - 9.5) The removal rate decreased. The results also showed that the removal rate varies between the elements and this depends on the concentration of the element present in the water, its chemical composition, and the degree of its binding to the substance used for treatment.
