Abstract

Pesticides contribute to environmental pollution, health problems, and resistance. Bioinsecticides offer an alternative solution. This study evaluated the potential of bay leaf juice (Syzygium polyanthum) as a bioinsecticide in the 2024 efficacy test against Aedes aegypti mosquitoes. This research is pseudo-experimental, with a post-test only control group design. The object of this study was female Aedes aegypti mosquitoes aged 2–5 days. This study used replication 5 times. The variables of this study were the variation of bay leaf juice 12%, 17%, 22%, 27%, 32%, and the number of deaths of Aedes aegypti mosquitoes after one hour. Data were analysed using One Way Anova. Bay leaf juice has the potential to kill Aedes aegypti mosquitoes. Variations in the concentration of bay leaf juice caused significant differences in the mortality of Aedes aegypti mosquitoes. The concentration of bay leaf juice at 31.136% is LC50, and the concentration of bay leaf juice at 52.803% is LC95. Other researchers can test the active ingredients of bay leaf juice that have the highest effect on killing Aedes aegypti mosquitoes.

Abstract

The increasing birth rate and number of toddlers each year have led to a rise in diaper usage, resulting in significant diaper waste. Improper management of this waste can cause environmental problems. One potential solution is utilizing diapers as raw material for liquid organic fertilizer production. This study aimed to determine the differences in bacterial starter addition and fermentation duration of liquid organic fertilizer from diapers in terms of nitrogen and potassium content. A quasi-experimental design with a post-test only control group was applied. The study focused on the hydrogel in the diaper’s inner layer. The independent variable was fermentation duration (12, 15, 18, and 21 days), while the dependent variables were nitrogen and potassium content, each with six replications. Data were analyzed using One Way ANOVA. Results showed average nitrogen content for fermentation durations of 12 days (0.34%), 15 days (0.43%), 18 days (0.53%), and 21 days (0.64%). The lowest nitrogen content was found at 12 days (0.32%), and the highest at 21 days (0.66%). Average potassium content for fermentation durations was 12 days (0.27%), 15 days (0.36%), 18 days (0.43%), and 21 days (0.54%). The lowest potassium content occurred at 12 days (0.25%), and the highest at 21 days (0.56%). In conclusion, there were significant differences in nitrogen and potassium content across fermentation durations. Further studies are recommended to optimize bacterial starter acclimatization, monitor temperature and pH, and apply sampling techniques according to national standards (SNI).

Abstract

Abstract. One of the efforts to prevent Dengue Hemorrhagic Fever is to control its vector, namely the Aedes aegypti. Research on mosquito repellents using natural active ingredients has developed a lot, for example, coriander seed extract oil (Coriandrum sativum L.). However, its pure extract is volatile and less effective when used directly as a repellent. The study aimed to analyze the effect of the hydroxypropyl methylcellulose (HPMC) gelling agent on the protective duration and power of coriander seed oil gel as a repellent against Aedes aegypti. The method used was a true experimental with posttest-only control group design. The treatment group was given coriander seed oil gel using HPMC concentrations of 7.5%, 10%, and 12.5% with six replications. The control group consisted of positive control, namely pure 60% coriander seed extract in 96% ethanol and negative control, namely the arm without any spread. Data analysis used the Mann-Whitney and Kruskal-Wallis test with a confidence level of 95%. The result showed that 7,5% of HPMC had the least number of Aedes aegypti landed for at least 6 hours with an average perch of 3.2%. The temperature and humidity of the research room were homogeneous. The addition of HPMC has increased protection and duration against the Aedes aegypti. The 7,5% HPMC result was complies to the Pesticide Commission’s standards (1995) with an average protective power of 97% for 6 hours. In conclusion, gelling agents such as HPMC can be an alternative to increase the protective power of for 6 hours. Abstrak. Satu upaya pencegahan penyakit Demam Berdarah Dengue adalah dengan mencegah kontak manusia dan vektornya, yaitu Aedes aegypti. Penelitian repelen nyamuk menggunakan bahan aktif dari alam telah banyak dilakukan, contohnya minyak ekstrak biji ketumbar (Coriandrum sativum L.). Akan tetapi, ekstrak murni biji ketumbar mudah menguap dan kurang efektif apabila digunakan secara langsung sebagai repelan Aedes aegypti. Penelitian ini bertujuan untuk menganalisis pengaruh variasi konsentrasi gelling agent hidroksipropil metilselulosa (HPMS) terhadap lama waktu perlindungan dan daya proteksi gel minyak biji ketumbar sebagai repelen terhadap Aedes aegypti. Metode penelitian ini adalah eksperimen murni dengan desain posttest-only control group design. Kelompok perlakuan diberi gel minyak biji ketumbar menggunakan konsentrasi HPMS 7,5%; 10%; dan 12,5% dengan 6 kali replikasi. Kelompok kontrol terdiri dari kontrol positif yaitu ekstrak biji ketumbar murni konsentrasi 60% dalam etanol 96% dan kontrol negatif yaitu lengan tanpa olesan apapun. Analisa data menggunakan uji Mann–Whitney dan Kruskal-Wallis dengan taraf kepercayaan 95%. Hasil penelitian menunjukan bahwa HPMS 7,5% memiliki jumlah nyamuk hinggap paling sedikit selama 6 jam pengamatan dengan rerata hinggap 3,2%. Suhu dan kelembaban ruang penelitian homogen. Penambahan HPMS terbukti memberikan peningkatan daya proteksi dan lama perlindungan yang sebelumnya belum maksimal terhadap nyamuk Aedes aegypti. Konsentrasi HPMS 7,5% sesuai standart Komisi Pestisida (1995) dengan rerata daya proteksinya adalah 97% selama 6 jam. Kesimpulan dari penelitian ini adalah gelling agent seperti HPMS dapat menjadi alternatif untuk meningkatkan daya proteksi selama 6 jam perlindungan.

Abstract

Continuous chemical dengue control can cause vector resistance and environmental pollution. Developing natural larvicides (bio-larvicides) from plant toxins like white chicory, which can poison Aedes aegypti larvae, is necessary for a sustainable alternative. This study aimed to analyze differences in active ingredients in white chicory leaves (Brassica pekinensis L) as bio-larvicide against Aedes aegypti larvae. This study was a pure experiment using a post-test-only control design using 1,225 Aedes aegypti instar III larvae with extracts of alkaloid active ingredients, flavonoids, and concentrations of 0%, 24%, 34%, and 40% with 3 times replication. Data were analyzed using a probit test, one-way ANOVA, and Post Hoc LSD. The results showed the potential of active ingredients in white chicory leaves against the death of Aedes aegypti larvae (p-value = 0.000). The average percentage of larval mortality concentration was 24%, 34%, 40%, in alkaloids was 41%, 60%, 66%, and in flavonoids was 45%, 64%, 68%. The active ingredient of white chicory leaves can kill Aedes aegypti larvae with LC50 in 29% alkaloids and 27% flavonoids.

Abstract

Noise in classrooms can disrupt communication between teachers and students, potentially affecting learning outcomes. Previous research indicates that noise exceeding environmental health standards may contribute to communication difficulties during lessons. This study aimed to analyze the effect of classroom noise and communication disruptions on students’ learning achievement. An observational analytic study with a cross-sectional design was conducted among 4th and 6th grade students at one of the elementary schools in South Surabaya. Noise levels were measured in the classrooms, and students were assessed for communication disruptions and learning achievement. Logistic regression was used for data analysis. All classrooms exceeded the environmental health noise threshold of 55 dB(A), with an average level of 67.45 dB(A). Noise was significantly associated with communication disruptions (OR = 5.118; p = 0.012). Classroom noise increased the risk of communication disruptions but did not directly affect students’ learning achievement. It is recommended to install soundproof partitions and double-glazed windows to reduce noise. Future studies should investigate the interaction between teaching methods and student achievement.

Abstract

Avocado leaves contain various compounds that are proven to cause death in Aedes aegypti larvae. In its use has limitations, namely the nature of the extract tends to cause turbidity in water, thus inhibiting the survival of Aedes aegypti larvae. In contrast to Aedes aegypti larvae, Culex sp larvae can live and develop well in dirty water. This study aims to assess the potential of avocado (Persea americana) leaf juice as a biolarvicide of Culex sp. The treatment consisted of five groups of avocado leaf juice concentrations, namely 0% (negative control), 2.5%, 5%, 7.5%, and 10%. Each using 20 Culex quenquefasciatus instar III larvae with replication 6 times. Mortality data of Culex sp larvae exposed to avocado leaf juice for 24 hours were analyzed using Anova test, Bonferroni test, and Probit test. The results showed that the mortality rate of larvae was 12,5%, 25%, 72,5%, and 92,5%, respectively. The Anova test showed that there was a significant difference between the concentrations of avocado leaf juice (p=0.000), the Bonferroni test showed that only the negative control (0%) and the 2.5% concentration, as well as the 2.5% and 5% concentrations, were not significantly different. The LC50 value obtained is 2.338%. It was concluded that avocado leaf juice has the potential as a biolarvicide against Culex sp.
