Deterioration of active ingredients due to exposure to temperature and humidity is a challenge in the development and storage of products containing active ingredients in the pharmaceutical industry. Exposure to high temperatures can accelerate the thermal degradation of active ingredients through mechanisms such as oxidation, decomposition, or Maillard reactions, resulting in decreased efficacy of active ingredients and the generation of undesirable degradation products. Meanwhile, high humidity also plays a role in accelerating the hydrolysis reaction of water-sensitive active ingredients, such as esters or amides, which reduces the chemical stability of the active ingredients. The combination of high temperature and high humidity often results in more complex degradation reactions compared to isolated temperature or humidity conditions, which can accelerate the decline in efficacy of active ingredients. Therefore, this article aims to explore various methods to view the stability of active ingredients under certain conditions, as well as provide recommendations for the development of more efficient formulations and storage strategies to maintain the stability and efficacy of active ingredients throughout the product's shelf life.

Kelembapan dan suhu merupakan faktor yang penting dalam budidaya jamur karena jamur membutuhkan kelembapan dan suhu tertentu untuk tumbuh dengan baik. Aspek lingkungan perlu diperhatikan dalam budidaya jamur adalah selama masa pemeliharaan dan suhu di dalam rumah jamur harus dijaga di kisaran 15-30°C. Suhu di bawah 15°C mengakibatkan tubuh buahnya mengecil dan tangkainya panjang, tetapi kurus. Jika suhunya di atas 30°C, suhu akan menyebabkan payung jadi tipis dan ukurannya kerdil. Kelembapan udara optimum yang dibutuhkan antara 80-90%. Jika kelembapan udara terlalu tinggi, jamur akan cepat membusuk dan jika kelembapan terlalu rendah, jamur akan menjadi kerdil dan kurus. Untuk memonitor tingkat kelembaban dan suhu dalam budidaya jamur tiram dibutuhkan sistem monitoring yang berguna untuk mengetahui kondisi tanaman secara otomatis dan real-time. Internet of Things (IoT) memiliki konsep yang bertujuan untuk memperluas manfaat yang tersambung dalam koneksi internet secara terus-menerus. Penggunaan Internet of Things (IoT) dalam memonitor suhu dan kelembapan dapat membantu efisiensi dan mempercepat pengiriman informasi kelembapan dan suhu udara tempat jamur dibudidaya. Jenis penelitian yang digunakan adalah R&D (Research and Development) dengan jenis model pengembangan prototyping. Hasil penelitian menunjukkan bahwa sistem otomasi dan pemantauan berbasis IoT bekerja dengan baik, dengan tingkat kesalahan pembacaan sensor suhu DHT11 dibandingkan thermometer digital berada di bawah 5% (dengan nilai error antara 0,37% hingga 3,10%). Selain itu, alat dapat mengirimkan notifikasi kepada pengguna ketika suhu atau kelembapan berada di luar rentang yang telah ditentukan, sehingga membantu menjaga kondisi optimal bagi pertumbuhan jamur.

Bioscrubber merupakan separator yang dapat digunakan untuk menurunkan konsentrasi hidrogen sulfida (H2S) pada biogas. Permasalahan yang mempengaruhi kinerja bioscrubber diantaranya yaitu jumlah oksigen berlebih (excess oxygen) dan suhu yang tidak sesuai dengan kebutuhan operasi sehingga menyebabkan tidak maksimalnya kinerja bioscrubber dalam menurunkan konsentrasi hidrogen sulfida (H2S). Untuk meminimalisir permasalahan ini maka dilakukan analisa data terkait kebutuhan jumlah oksigen berlebih dan suhu operasi yang optimal. Pada penelitian ini dilakukan pengumpulan data secara langsung yaitu dengan pengambilan data produksi biogas di Pembangkit Listrik Tenaga Biogas (PLTBg) Sei Mangkei yang kemudian dilakukan pengolahan data terkait kebutuhan excess oxygen dan suhu operasi pada proses separasi H2S. Dari penelitian yang dilakukan, diketahui bahwa proses penurunan konsentrasi H2S menggunakan bioscrubber yang ada di PLTBg Sei Mangkei membutuhkan excess oxygen sebanyak 363,4% dari kebutuhan oksigen teoritis dan suhu operasi 38oC untuk dapat menurunkan konsentrasi H2S hingga 97,5%.

AEFI or Post-Immunization Adverse Event is a medical condition that is assumed to be related to immunization. Reactions that arise due to AEFI include high fever, abscesses/festering, seizures. The 2018 Lampung Provincial Health Office report noted that 32.6% experienced AEFI with the largest number being those experiencing high fever, namely 29.5%, festering 8.3%, seizures 0.97%, and others 0.57%. Reducing or controlling and controlling fever in children can be done in various ways, including pharmacologically and physically (non-pharmacologically), namely by using heat energy through conduction and evaporation methods. the effect of onion compress on reducing the baby's body temperature during fever after DPT immunization at PMB Yunita Vero Miza Lampung in 2024. Type of analytical survey research with a Post test Only Control Design approach. The research results showed a decrease in baby's body temperature after DPT immunization in the intervention group and control group after being given shallot compress with an average difference of 1.060. The results of the paired t-test obtained a p value = value 0.000 (p <0.05). there is an effect of onion compress on reducing the baby's body temperature during fever after DPT immunization at PMB Yunita Vero Miza Lampung

The incidence of fever following DPT (Difteri Pertusis Tetanus) immunisation is relatively high, often necessitating treatment with fever-reducing drugs, which may have adverse effects on infants. Therefore, non-pharmacological methods that are effective, safe, economical, and practical are essential. This research aims to investigate the effectiveness of an onion compress combined with virgin coconut oil (VCO) in reducing body temperature in infants following DPT immunization. The study employed a quasi-experimental method with a one-group pre-test and post-test design. The study population consisted of infants who received DPT immunization in the midwife's independent practice (PMB) working area at the Pudak Payung Health Centre, Semarang, with a total sample size of 48 infants selected via purposive sampling. Data were collected through observation, analysed using descriptive statistics, and the Wilcoxon signed-rank test. Prior to the intervention, 47 infants (45.92%) exhibited fever, and 1 infant (2.08%) had a high fever post-immunisation. Following the application of the shallot compress with VCO, all infants (100%) showed a reduction in body temperature, with none experiencing fever thereafter. The analysis indicated a significant effect of the onion compress combined with VCO on reducing body temperature (Z = -6.042, p < 0.01). The average body temperature of infants post-DPT immunisation decreased from a mean of 38.5°C before the intervention to 37°C afterwards. In conclusion, the use of an onion compress with VCO effectively reduces body temperature in infants following DPT immunization. This non-pharmacological approach presents a promising alternative to conventional fever management strategies.

In simplifying the process of monitoring the temperature of electric vehicle batteries, especially in discharging conditions, a remote electric vehicle battery temperature monitoring system was created. The problem with the previous monitoring system was that there was no electric battery temperature monitoring system, so users could not monitor the temperature condition of the vehicle battery when in use. The purpose of this study is to design an Internet of Things (IoT)-based electric vehicle battery temperature monitoring device system using the web and add a data logger to monitor battery temperature remotely and find out the difference in temperature values from the device with a thermogun. And the addition of a cut off feature when the battery overheats as one of the safety. The research method uses experiments, namely by comparing the speed between 30km/h and 50km/h and comparing the readings of the monitoring device with a thermogun. In proving the performance of the monitoring equipment, it is carried out with a distance of 1km, 2km, and 3km and in sloping road conditions. The data obtained were then analyzed using the paired T-test method. The results of the study showed that the tool worked quite well with the highest error value of 3.88%. And the battery temperature value between the speed of 30km/h and 50km/h is a significant difference with a P-value result of 0.035 which means that H0 is rejected and H1 is accepted.

Gas Sulfur adalah salah satu polutan berbahaya bagi manusia. Akibat utama polutan (SO2) terhadap manusia adalah terjadinya iritasi pada sistem pernafasan. Terutama kesehatan bagi usia lanjut dan penderita yang mengalami penyakit kronis pada sistem pernafasan dan kardiovaskular yang sangat sensitif jika kontak dengan (SO2).
