Polyhydroxyalkanoates (PHAs), microbial bioplastics, not only were similar in properties with those made of petrochemical products, they were also completely biodegradable. At the moment, the price of PHAs was still high. This research was conducted to investigate the ability of Ralstonia eutropha to produce PHAs on a sago starch-based substrate, one of the cheap and abundantly renewable resources in Indonesia, and to characterize the PHAs produced. The microorganism was grown on the hydrolyzed sago starch with an initial sugar concentration of 30 g/lIt was found that the best value of the maximum specific growth rate (Âµmax) was Â 0,188 h-1. Kinetic parameters at 96 hour-batch fermentation showed the respective final cell and PHA concentrations of 4,41 g/L and 1,44 g/L. The yields of cell biomass (Yx/s), PHAs per gram of cells (Yp/x), PHAs per gram of substrate (Yp/s) and the percentage of substrate consumption Â (âˆ†S/So) were, 0.15 g cell/g sugar; 0.35 g PHA/g cells; 0.06 g PHA/g sugar and 99%, respectively. Â The PHAs produced were predominantly composed of poly(3-hydroxybutyrate) (PHB) as the functional groups with a melting point of 163,96 oC.Keywords : hydrolyzed sago starch, PHA, Ralstonia eutropha

Traditional medicine in Indonesia, as part of the archipelago's cultural heritage, has been the main choice in curing people's illnesses. Despite the growth of modern medical services, many still rely on traditional medicine, including reflexology, herbal drinks, aromatherapy, chiropractic therapy, cupping, and acupuncture. This study aims to examine and discuss traditional medicine in Indonesia, focusing on Battra (traditional medicine) and various types of traditional medicine such as reflexology, herbal drinks, aromatherapy, chiropractic therapy, cupping, acupuncture, as well as traditional medicine in the context of Islamic law. This research uses a descriptive qualitative approach through literature study. The results show that there is a link between the social relationship between traditional healers and patients as a legal relationship in terms of their respective interests. In addition, traditional medicine in Indonesia is not only seen as a cheap alternative, but also as an inseparable part of cultural identity and ancestral heritage that needs to be preserved. Health law also plays a role in regulating and protecting traditional medicine to prevent abuse and harmful practices.

The Hospital Management Information System (HMIS) is an information technology platform that integrates all service workflows in a hospital to obtain precise and accurate information. The use of HMIS is considered essential for improving healthcare service quality and hospital operational efficiency. This study aims to explore the impact of HMIS on the efficiency and effectiveness of human resource (HR) performance in hospitals. The research employs a literature review method, collecting data from various relevant sources such as journals, books, and online resources, primarily from the last five years (2020–2024). The implementation of HMIS in hospitals has demonstrated improvements in HR performance efficiency and effectiveness. HMIS facilitates better data management, enhances coordination among work units, and accelerates healthcare service processes. However, effective implementation heavily relies on management support, workforce readiness, and the availability of adequate technological infrastructure. Investments in HMIS not only enhance HR performance but also contribute to the overall improvement of service quality for patients.

ABSTRAKPerubahan Konstitusi merupakan suatu hal yang tidak dapat dihindari. Konstitusi suatu negara pada hakekatnya merupakan hukum dasar tertinggi yang memuat hal-hal mengenai penyelenggaraan negara, karenanya suatu konstitusi harus memiliki sifat yang lebih stabil dari pada produk hukum lainnya. Namun, karena sistem ketatanegaraan tidak dijalankan dengan baik, maka menyebabkan pemerintahan kacau dan terjadi ketidak percayaan dalam menjalankan pemerintahan. Sehingga menyebabkan terjadinya perubahan pada konstitusi melalui dekrit persiden kembali menggunakan UUD 1945. Tujuan penelitian untuk mengetahui tentang perubahan konstitusi di Indonesia. Penelitian ini bersifat kualitatif deskriptif dengan metode studi pustaka. Hasil penelitian menunjukkan bahwa perubahan konstitusi mempunyai cara-cara atau prosedur tertentu dalam pergantian maupun perubahannya tetapi harus disesuaikan dengan perkembangan masyarakat yang terjadi dalam suatu negara. Diharapkan dalam perubahan atau pergantian konstitusi bisa beradaptasi dengan zaman maupun masyarakat. Sehingga konstitusi bisa memberikan pertahanan pada negara untuk membatasi kekuasaan, mengendalikan perkembangan dan situasi politik yang selalu berubah serta upaya untuk menghindari adanya penyalahgunaan kekuasaan dalam negara. ABSTRACTConstitutional change is something that can’t be avoided. The constitutional of a country is essentially the highest basic law that contains matters concerning the administration of the state, therefore a constitution must have a more stable nature than other legal products. However, because the constitutional system is not run properly, it causes caotic governmant and distrust in running the governmant. Thus causing changes to the constitution through a presidential decree to return to using the 1945 constitution. The purpose of the research is to find out about changes in the constitution in indonesia. This research is descriptive qualitative with literature study method. The results showed that changes to the constitution have certain ways or procedures in changing or changing it but must be adapted to the development of society that occurs in a country. It is hoped that in changing or changing the constitution can adapt to the times and society. So that the constitution can provide a defense to the state to limit power, control develpoments and political situations that are always changing and efforts to avoid abuse of power in the state.

Acute Respiratory Tract Infection (ARI) remains a significant public health problem in Indonesia, especially among vulnerable groups such as toddlers and the elderly. Low public knowledge about ARI prevention is a risk factor contributing to the high morbidity rate. This study aims to determine the effect of education using pocket books on increasing public knowledge about ARI in Pangkalan Dodek Baru Village, Batu Bara Regency. The study used a pre-experimental design with a pre-test and post-test approach on 58 respondents selected using an accidental sampling technique. The research instrument was a validated closed-ended questionnaire, and data analysis was conducted using the Wilcoxon test. The results showed that before the intervention, 63.8% of respondents had good knowledge, 20.6% had sufficient knowledge, and 15.6% had insufficient knowledge. After the intervention, all respondents (100%) had good knowledge. The average pre-test score was 7.66, increasing to 9.88 in the post-test, with the Wilcoxon test yielding a p-value of 0.000 (<0.05). Thus, it can be concluded that education using pocket books has a significant impact on increasing public knowledge about ARI. This simple educational medium can be used as an alternative promotional and preventive strategy in efforts to control ARI in the community.
