Balita usia di bawah 5 tahun dengan kondisi malnutrisi merupakan permasalahan yang banyak ditemukan Indonesia, dan sekitar 53% diantaranya disebabkan oleh rendahnya nafsu makan. Jamu cekok adalah obat tradisional Indonesia yang umumnya digunakan untuk meningkatkan nafsu makan untuk anak-anak. Jamu cekok biasanya diberikan kepada anak dengan cara meremas campuran herbal dengan tangan dan langsung dimasukan kedalam mulut anak supaya cairan yang dihasilkan langsung masuk ke dalam tenggorokan anak. Bahan utama jamu cekok adalah rimpang Curcuma xanthorrhiza Roxb (Temulawak) dengan bahan aktif kurkumin dan xantorizol. Walaupun fungsi secara empiris dan potensi pasar sudah cukup menjanjikan, tetapi umumnya metode yang digunakan untuk mengeringkan bahan baku dengan sinar matahari dan proses memeras herbal memiliki potensi kontaminasi mikroba yang sangat besar. Perubahan proses pengeringan menggunakan oven dan ekstraksi menggunakan air dapat diaplikasikan untuk meningkatkan sanitasi dari jamu cekok. Pada penelitian ini, dilakukan ekstraksi temulawak menggunakan air dengan dilakukan beberapa perbedaan diantaranya kondisi suhu pengeringan (30Â°C dan 50Â°C), suhu ekstraksi (50Â°C, 75Â°C, dan 100Â°C), serta rasio berat dari pelarut dan bahan baku (10:5, 10:2, 10:1). Estimasi kandungan kurkumin dan penentuan xantorizol secara kualitatif digunakan untuk menentukan efektivitas dari proses ekstraksi menggunakan air, sedangkan peningkatan sanitasi dapat dilihat dari jumlah pertumbuhan bakteri. Kandungan kurkumin paling tinggi dihasilkan dari rasio pelarut terhadap bahan baku 10:2. Suhu ekstraksi paling tinggi menghasilkan kandungan kurkumin yang paling tinggi, tetapi sebaliknya memiliki kandungan xantorizol yang paling rendah. Pengeringan menggunakan oven dan ekstraksi menggunakan air menunjukan peningkatan sanitasi yang terlihat dari penurunan jumlah bakteri yang sangat signifikan.

Biodiesel is one of the most feasible energy sources that can be used as a replacement for fossil fuel. Biodiesel has several advantages over conventional fuels because of its availability, renewability, and high combustion efficiency. However, biodiesel that contains unsaturated fatty acid methyl esters is prone to oxidation during the blending process and storage period. The complete oxidation reaction of biodiesel produces insoluble gums that could potentially plug the fuel engines. This reaction has become the main barrier for biodiesel to compete with other biofuels. Among several methods, the addition of antioxidants is the most cost-effective method to prevent the oxidation reaction in biodiesel. Pyrogallol (PY), which is one of the best antioxidant additives for biodiesel, was used in this research to evaluate its performance. However, the fact that PY is partially soluble in biodiesel is considered a problem in the application of PY as an antioxidant additive in biodiesel. In this research, three different surfactants were added to increase the dispersion and performance of PY in biodiesel. Dispersion test, acid number analysis, and iodine value analysis were performed to evaluate the effect of surfactant addition on the dispersion and antioxidant performance of PY in biodiesel. The surfactant glycerol monostearate showed the best result in increasing the dispersion of PY in biodiesel compared with sorbitan monooleate and polyglyceryl-4-isostearate (PG4IS). By contrast, the best performance of PY in preventing the oxidation of biodiesel was achieved with the addition of PG4IS.

Maintaining job satisfaction among civil servants is essential for ensuring the effectiveness and efficiency of public service delivery. In this context, factors such as work-life balance, work stress, and psychological capital play a crucial role. This study investigates the influence of work-life balance and work stress on job satisfaction, with psychological capital serving as a mediating variable among civil servants at the Regional Personnel Agency (BKD) of the Special Region of Yogyakarta (DIY). The population in this study consists of all BKD DIY employees, and the sampling technique employed is exhaustive sampling, resulting in a total of 85 respondents. Data were collected through the distribution of offline, hard-copy questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4 software. The results indicate that work-life balance has a significant positive effect on job satisfaction, while work stress has a significant negative effect. In addition, psychological capital significantly mediates the relationship between work-life balance and job satisfaction, as well as the relationship between work stress and job satisfaction. These findings highlight the importance of strengthening psychological capital to enhance job satisfaction among civil servants.
