The part of the basil plant is the leaves which have various types of benefits if studied further. With the introduction of secondary metabolites, it can be said that basil leaves contain eugenol compounds. The eugenol compound can be used as a reducing agent in the synthesis of TiO2 nanoparticles. The precursor used in the synthesis of TiO2 is titanium isopropoxide which has an oxidation state of +4. By utilizing the green synthesis method, TiO2 was reacted with basil leaf extract and then characterized using XRD and FTIR. The resulting particle size is 10.86 nm. And FTIR shows a wave number of 874.59 which represents the Ti-O functional group. Photocatalytic activity can take advantage of the synthesis of TiO2 nanoparticles by placing the nanoparticles in a methylene blue solution which has a concentration of 20 ppm and varies based on contact time and adsorbent mass. Photocatalytic activity testing obtained a degradation percentage of 79%-84% which varied based on adsorbant mass and contact time. Varying the adsorbant mass and time results in a degradation percentage that increases with each additional mass but will not increase again if it has reached the optimum phase and can reduce the degradation percentage.

Stunting yaitu kekurangan gizi menahun atau kronis yang dapat terlihat pada tinggi badan balita lebih pendek dari balita seusianya. Pravelensi balita yang terjangkit stunting secara nasional sebesar 37,6 persen (2007) dan mengalami penurunan menjadi 35,8 persen (2010). Namun meningkat kembali menjadi 37,2 persen (2013) dan menurun kembali menjadi 29,9 persen (2018). Data tersebut menunjukkan pravelensi stunting yang tidak menentu. Banyak faktor yang mempengaruhi stunting khususnya pengetahuan orang tua mengenai mengenai gizi seimbang pencegah stunting. Pencegahan stunting perlu dilakukan dengan pemantauan status gizi secara berkala dan pemenuhan gizi seimbang Balita. Berdasarkan penelitian tersebut, maka dilakukan pemberian makanan bergizi seimbang pencegah Stunting dan sistem pakar deteksi dini stunting dengan sistem pakar. Hasil analisis menunjukkan bahwa metode Dempster Shafer dapat mendeteksi stunting balita lebih baik dengan akurasi 90% dibandingkan metode Naive Bayes dengan akurasi 75%. Aplikasi ini bertujuan membantu menurunkan angka stunting balita yang masih menjadi masalah saat ini.

Procurement is a recurring activity in a company's business process. While the traditional procurement process is often considered less efficient and effective, it requires a better solution. The traditional procurement process also often requires a long time, high cost, and lack of transparency. This can lead to inefficiency and the risk of misuse. This research aims to develop a more efficient and effective procurement application model using SDLC and waterfall methodologies. This research uses observation methods to study the current procurement process and interviews to get input from stakeholders regarding application needs. The results showed that the developed procurement application model can help companies in a more efficient and effective procurement process. This application model can help companies to save time and costs, as well as increase transparency and accountability of the procurement process.

Early childhood development is closely related to the environment and family. The aim of this research is to explain the responsibilities of parents in their children's education. This research uses qualitative research methods which are presented in an educational descriptive manner. The results of this research show that parents are the first place where children receive education in the family. A child's personality is initially formed in the family.

Adanya PSBB sebagai bentuk penanggulangan penyebaran pandemi Covid19 berdampak pada sektor transportasi dan logistik, karena berkurangnya pengguna akibat dari pembatasan mobilisasi masyarakat oleh pemerintah. Penurunan pengguna ini membuat perusahaan mengalami penurunan penghasilan. Penelitian ini bertujuan untuk mengetahui pengaruh fenomena pandemi Covid-19 terhadap potensi financial distress perusahaan dan untuk mengetahui apakah terdapat perbedaan potensi financial distress yang signifikan antara sebelum dan selama pandemi Covid-19. Jenis data pada penelitian ini adalah data kuantitatif yang berupa laporan keuangan perusahaan sektor transportasi dan logistic. Objek pada penelitian ini yaitu perusahaan sektor transportasi dan logistik yang tercatat di Bursa Efek Indonesia pada tahun 2017-2022. Metode yang digunakan untuk menentukan sampel yaitu Purposive Sampling, dengan data sampel yang digunakan sebanyak 12 perusahaan pada sektor transportasi dan logistik yang terdaftar di Bursa Efek Indonesia dari tahun 2017-2022. Teknik analisis financial distress pada penelitian ini menggunakan model prediksi kebangkrutan Fulmer. Kemudian hasil analisis model Fulmer tersebut dilakukan pengujian normalitas data Shapiro-Wilk dan dilakukan uji beda Wilcoxon Signed Rank Test dengan menggunakan program SPSS Statistics. Hasil penelitian ini menyimpulkan bahwa pandemi Covid-19 berpengaruh terhadap potensi financial distress pada perusahaan transportasi dan logistik. Akan tetapi, pandemi Covid-19 tidak memberikan perbedaan pengaruh yang signifikan terhadap potensi financial distress sebelum dan selama pandemi Covid-19.
