Pollution control strategy on the Boyolali Gandul River borderline: SWOT analysis
Full text linkRiver 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

Analysis of factors affecting organic rice exports in Indonesia
Full text linkThe 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

The study used four female goats weighing 25 - 36 kg with a 4 x 4 Latin square design. Livestock were placed in the metabolism cage individually. The provision of ration was conducted according to the dry material requirement, which is 3% of body weight. Feeding was carried out twice daily in the mornings at 08.00 and afternoons at 16.00, and drinking water was provided ad libitum. The variables observed were consumption, coefficient of dry matter and nutrients, rumen metabolite products and blood chemistry propyl. The variables measured were the nutritional content, consumption, rumen metabolite products, digestibility coefficient, and blood chemistry levels. The replacement of elephant grass with ULMS up to 40% of the 60% forage in the ration did not significantly affect digestibility, rumen fluid pH, BUN, or total blood protein, but had a significant effect on the consumption of dry matter, and organic matter, rumen NH3, and VFA levels
Data mining based on dynamic waste information system in Surakarta City
Full text linkThe 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 factor
The experiment of stem cutting planting position in increasing sweet potato (Ipomea batatas L.) production in horticulture learning
Full text linkThis study aimed to discuss: (1) the effect of different positions of stem cuttings on sweet potato production; and (2) whether this practical experiment-based approach is effectively implemented in horticulture learning. This experimental research used a completely randomized design. The population was sweet potato plants. The research sample was the tip cuttings of sweet potato plants. The length of the cuttings was 30 cm, measured from the tip of the plant’s stem with relatively the same number of segments. The number of treatments was 3: upright Po (180°), inclined P1 (45°) and flat P2. The number of repetitions was six times, and the number of samples for each treatment was 20 cuttings of the sweet potato stem tips. Thus, the number of sweet potato stem tip cuttings needed in this study is 3 X 6 X 20 cuttings = 360 (three hundred and sixty). Based on the ANOVA test, a significant value of 0,005 was obtained, far smaller than the determined significance level of 0,05. It means there is a significant difference between the weights of sweet potato tubers between treatments. In conclusion, there is a significant difference between the upright/90° and slanted/45° treatment and between the upright/90° and horizontal treatment. Meanwhile, the treatment between slanted/45° and horizontal showed no significant difference. Overall, the best sweet potato production is obtained by planting horizontally with an average tuber weight of 313 grams. It can be concluded that this practical experimental method is very effectively implemented in the horticulture learning process
