Abstract

Forest chili leaves (Piper caninum Bl.) has a potential to become an alternative to conventional antibiotics. This study aims to determine the Minimum Inhibitory Concentration (MIC) of forest chili leaf extract, assess the Lethal Concentration (LC50), and analyze the phytochemical composition of the extract. This study also conducted a Completely Randomized Design (CRD) with four repetitions. The agar well diffusion method is used in this study with various concentrations such as T1 ethanol 96% (negative control), T2 (5% concentration), T3 (10% concentration), T4 (15% concentration), T5 (20% concentration), T6 (25% concentration), and T7 Ciprofloxacin 1% (positive control). Data were subjected to ANOVA at a significance level of 5% and further analyzed using Duncan's test. The results showed that all concentrations of forest chili leaf extract (P. caninum Bl.) exerted a statistically significant effect (P 0.05) against Staphylococcus epidermidis bacteria. The research found that the most effective concentration to inhibits S. epidermidis is at 25%, which generates an inhibitory zone of 25.38 ± 0.52 mm. The estimated MIC value for forest chili leaf extract against S. epidermidis was found to be 0.2%, producing an inhibitory zone of 6.38 ± 0.32 mm. Additionally, the calculated LC50 value was 0.26%. Phytochemical screening revealed the presence of various bioactive compound groups in the forest chili leaf extract, including alkaloids, flavonoids, phenols, tannins, and steroids.

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

Cashew nut skin is considered as waste, whereas cashew nutshell extract, or called CNSL (Cashew Nut Shell Liquid), has the potential as a botanical insecticide that can control insect pests. Helopeltis sp is a pest that often attacks cacao plants. The study aims to determine the effectiveness of cashew nutshell extract as a botanical insecticide to control  Helopeltis sp. in cacao plants. The study used a randomized block design (RBD) with seven treatments and three replications. Testing CNSL on adult (imago) and pre-adult (nymph) insects. CNSL concentrations used are 0%, 3.125%, 6.25%, 12.5%, 25%, 50% and 100%. The results showed that cashew nutshell extract has strong toxicity. A concentration of 3.125% can kill 100% of the imago Helopeltis sp. (72 hours after application) for the nymph Helopeltis sp. (48 hours after application). LC50 values 24 hours after application for imago and nymph were 4.63% and 0.94%, and LC99 for imago and nymph was 42.62% and 23.89%.  Furthermore,  cashew nut extract can be used as a botanical insecticide to control other plant pests.

Abstract

The objective of the research is to determine the impact of solid application on the growth of oil palm seedlings and to identify the optimal dosage for promoting their growth in the main nursery. From June to October of 2022, the research was carried out at the Islamic University of Indragiri's Agriculture Faculty's experimental farm. The investigation was conducted using a completely randomised design (CRD) with six treatments: no solid, 150 g/polybag, 200 g/polybag solid, 250 g/polybag solid, 300 g/polybag solid and 350 g/polybag solid used. Each treatment was replicated three times. The collected data were subjected to a 5% level Duncan Multyple Range Test after being statistically analysed using analysis of variance. The findings demonstrated a strong relationship between solid application in oil palm medium and the height of the seeds, the number of leaves, the diameter of the hump, and the dry weight of the oil palm seedlings. The optimal dosage for promoting oil palm seedling growth in pre-nursery is 300 grammes per polybag, applied in a solid form
