Abstract

Introduction: The traditional textile art of Tenun Cepuk from Nusa Penida is highly valued for its intricate designs and cultural importance. Nevertheless, the environmental predicament posed by the textile industry's wastewater, particularly due to dye-related contamination, is substantial and necessitates sustainable remedies. Seaweed powder shows considerable promise as an adsorbent for addressing dye wastewater issues within the textile sector. An essential aspect of this endeavor is to explore the dynamic relationship between different thicknesses and contact durations, as it is pivotal in optimizing the adsorption capacity and effectiveness of seaweed powder for treating dye wastewater..Method: This research, utilizing an Experimental research design with a Posttest Only Control Group Design, is conducted to evaluate the influence of an intervention on the experimental group as compared to the control group. Euchema cottonii seaweed, sourced from Nusa Penida, is employed as the adsorbent. Different thicknesses of seaweed powder, namely 5 cm, 10 cm, and 15 cm, are added to tanks. Subsequently, wastewater samples from the Cepuk weaving process are introduced into each of the experimental tanks, alongside a control group. The process is allowed to continue for 24 and 72 hours as varying contact durations. The adsorption outcomes are then subjected to analysis, including parameters such as TSS, TDS, BOD5, and COD, at the Panureksa Denpasar Laboratory.Results: The application of seaweed powder as an adsorbent proves to be efficient in decreasing TDS, TSS, BOD5, and COD levels in Cepuk textile dye wastewater. The extent of reduction relies on the thickness of the adsorbent and the duration of contact. Increased thickness of the adsorbent results in a pronounced reduction in TDS, TSS, BOD5, and COD levels, leading to an improvement in the quality of wastewater and a safer environmental impact. Specifically, an adsorbent with a thickness of 15 cm effectively reduces TDS to permissible levels. Extended contact times also lead to a significant decrease in these levels..Conclusion: The application of seaweed powder is a viable method for reducing TDS, TSS, BOD5, and COD levels in textile dye wastewater. The thickness of the adsorbent and the duration of contact play a substantial role in improving the quality of the wastewater.

Abstract

Stunting is still a health problem faced by Indonesian children. The incidence of stunting according to Indonesian Nutrition Status Survey (SSGI) in 2021 was 24.4% and in 2022 it’s decrease to 21.6%. There were exceeds from WHO recommended requirement 20%. Holistic efforts from the government and society were needed to accelerate stunting reduction. This research aims to produce an integrated approach model such as nutrition education, tuina massage and psychomotor training (Gina Latrik) in accelerating to decrease of stunting rates. This type of research is true experimental. Subjects were divided into two groups, ie;  “Gina Latrik B” treatment group (balanced nutrition education, massage Tuina therapy with a frequency of 3–5 times/week and psychomotor training) and control group “Gina Latrik A” (balanced nutrition education, massage therapyTuinawith a frequency of 1–2 times/week and psychomotor training). The average knowledge level of toddler mothers after given the intervention was 83.66 ± 4.04% in the control group and 87.98 ± 5.88% in treatment group and significant difference with p=0.040 (p0.05). The results of research on macronutrient intake (energy, protein) in two groups showed significant differences (p0.05) and nutrient intake in Gina Latrik B was better than Gina Latrik A. Nutritional status results with height/age shows that the Z score = 2.17 ± 0.379 (Gina latrik A) dan 2.73 ± 0.452 for Gina Latrik B) with p=0.003 (p0.05), there was a significant difference on t-independent analysis. That means the Gina Latrik B was better than Gina Latrik A. Psychomotor development shows an increase in both groups, in Gina Latrik A there is an increase in psychomotor ability in the "appropriate" category of 33,30% to 60%. Meanwhile, in the Gina Latrik B group there was a sharp increase from 39.39% to 90.91%. Based on analysist independent showed a significant difference p = 0.003 (p0.005). Based on the results it can be prove that Gina Latrik B intervention was better for decreasing of stunting compared to Gina Latrik A.

Abstract

This study aims to analyze the correlation between the area of oil palm plantations and oil palm production in Indonesia, especially in the Sumatra and Kalimantan regions which are the centers of oil palm plantation distribution. Data collection using secondary data from the Central Statistics Agency (BPS), this study aims to determine the relationship between the increase in land area and oil palm plantation production over the past 10 years. This study uses a quantitative method with a correlative approach. Data analysis was carried out using a bivariate correlation Pearson correlation test to determine the positive relationship between plantation area and oil palm production. The results of the analysis showed a significant positive relationship between the land area variable and oil palm production in both the Sumatra and Kalimantan regions, this is indicated by a positive number and a strong correlation of 0.852 for the Sumatra region and very strong, namely 0.996 for the Kalimantan region. In addition, the results of the interpretation of the correlation by looking at Sig. (2-tailed) also show that between the land area variable and production there is a significant correlation, namely 0.002 for the Sumatra region and a value of 0.000 for the Kalimantan region. Although the correlation between land area and production shows a positive value and has a very strong correlation, there are still other factors such as technology, climate, and management practices that also play a role in influencing palm oil production results.

Abstract

Some types of plants can serve as plant-based insecticides. Ginger (Zingiber officinale) and Turmeric (Curcuma domestica) are ingredients that are often used as pesticides on various plant pests. Spodoptera litura itself is a pest that is quite annoying in various plants. The study aimed to examine ginger (Zingiber officinale) and turmeric (Curcuma domestica) extracts as insecticides to control armyworms (Spodoptera litura). The research was carried out in Pelemsari Village, Prenggan, Kotagede, Yogyakarta from May to June 2022. The study used a Complete Random Design (RAL) with 2 factors. The first factor is the type of extract, namely ginger and turmeric. The second factor is the concentration of the extract which consists of 3 levels, namely 20%, 40%, 60% and control, each treatment is repeated 3 times. To find out the real difference between the data treatments, the observation results were analyzed with Duncan's Multiple Range Test (DMRT) at the real level of 5%. Ginger and turmeric extracts at a concentration of 20% have been able to control S. litura larvae. Ginger extract is more effective compared to turmeric extract based on the mortality test, efficacy, death rate, and feed spoilage rate of S. litura larvae. The research is still in the experimental stage in the laboratory and needs to be tested in the field to get an effective dose for armyworms.

Abstract

The nutritional state of a plant can range from acute poisoning to acute deficiency. For broad purposes, it could be helpful to categorize the nutritional status into four groups: surplus, ideal, inadequate, and extensive. Nutrients that are considered essential include boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni), molybdenum (Mo), calcium (Ca), magnesium (Mg), sulfur (S), and chlorine (Cl). Every nutrient has an effect on the metabolism of plants at every stage of their growth. Of course, breeding techniques are used to improve the efficiency with which plants take nutrients, such as enhancing nutritional utilization and optimizing nutritional efficiency through root modifications. In nutrient-poor soils, for instance, optimizing root shape to boost nutrient uptake efficiency can boost plant output. While developing organs, particularly reproductive organs, transpire at low rates, they need a lot of mineral resources to expand actively. Plants' nutritional efficiency may be effectively increased by using genetic engineering to transfer genes from other species, so overcoming the restrictions imposed by genetic variation within the same species.
