Abstract

The hospital is a place to organize health service efforts, including promotive, preventive, curative, and rehabilitative; these health services are carried out through emergency installations, outpatient installations, and inpatient installations. The emergency room is a special service room that provides comprehensive and continuous services 24 hours a day for patients. Patients who enter the hospital emergency room certainly need fast and precise help, and for that reason, there needs to be a standard for providing emergency services so that patient disability and death can be prevented. The purpose of this study is to know the definition, legal basis, and legal consequences if informed consent is not implemented. The research method used is a normative juridical approach or normative legal research, namely legal research conducted by examining library materials or secondary data. The results showed that in an emergency situation, to save the patient's life and prevent disability, consent for medical treatment is not required, but the doctor must make a medical record regarding the actions taken and then explain after the patient is conscious. Hence, we can conclude that informed consent or an explanation of the approval of medical action to patients in the hospital must be carried out at the beginning before the action except in the emergency room. The implementation of informed consent in the emergency room cannot be done at the beginning because the main thing is to save lives first, but all actions must be recorded in the medical record and delivered to the patient after completion of the action when the patient is conscious.

Abstract

Unnatural work postures or awkward work postures are work postures in which the body moves away from its natural position, such as a back that is too bent, hands in a raised position, squatting, body twisting, and so on. Complaints on the musculoskeletal system are complaints on parts of the skeletal muscles that are felt by a person. If the muscles receive static loads repeatedly and for a long time, it can cause complaints in the form of damage to joints, ligaments and tendons. Whereas in Indonesia, based on the results of basic health research (Riskesdas, 2013), the prevalence of joint disease based on the results of diagnoses by health workers in Indonesia is 11.9% and based on diagnoses or symptoms, 24.7%.This study aims to determine the relationship between work posture and complaints of musculoskeletal disorders (MSDs) in workers in the cyclamate production department at PT. Batang Alum Industrie with correlation description research design, cross sectional approach, a sample of 74 employees and total sampling technique. The results of the rank spearman test analysis found a significant relationship between work posture and complaints of musculoskeletal disorders (MSDs) in workers in the cyclamate production department at PT. Batang Alum Industrie results in a sig value of 0.000 (ƿ > 0.05) and a correlation coefficient of 0.409.Companies should provide training or guidance regarding good work posture according to ergonomics to workers so that workers apply and know good and correct work postures so that workers are comfortable at work. Workers should stretch their muscles to take advantage of their rest hours by doing muscle relaxation movements for about 5-10 minutes to improve blood circulation throughout the body.

Abstract

Saat ini kebutuhan bahan bakar minyak terus menjadi besar bersamaan dengan meningkatnya populasi dan berkembangnya Teknologi. Namun cadangan sumber energi minyak bumi yang berasal dari fosil terus menjadi menipis karena sifatnya yang tidak dapat diperbaharui. oleh karena itu, perjuangan buat mencari asal tenaga alternatif yang dapat diperbaharui (renewable) butuh ditingkatkan. Salah satu sumber tenaga alternatif yang kala ini banyak dibesarkan ialah Fatty Acid Methyl Ester (FAME) yang umum diketahui dengan nama Biodiesel. Biodiesel ialah bahan bakar alternatif yang menjanjikan serta dapat terbuat dari minyak goreng sisa, lemak hewani ataupun minyak nabati yang dikonversikan ke dalam metil ester lewat proses transesterifikasi memakai alkohol. Reaksi transesterifikasi ini membutuhkan katalis dalam penggunaanya. Setelah di amati, katalis heterogen menjadi katalis yang paling efektif dalam pembuatan biodiesel melalui reaksi transesterifikasi.

Abstract

Myofascial syndrome is a condition characterized by the presence of a hypersensitive region, called a trigger area of muscle or loose connective tissue, together with a specific pain reaction in the area associated with that point when the Trigger Point (Myofascial Trigger Point) is touched or palpated. This causes a localized seizure response known as the confluence sign, which is a shortening of the fibrous muscle fiber. Physiotherapy examination includes pain assessment with Visual Analogue Scale, muscle spasm with palpation, joint range of motion with goniometer, muscle weakness with Manual Muscle Testing, and functional activity with Neck Disability Index. In this case, the interventions chosen were Infra Red (IR), Ultrasound (US), Myofascial Release and Contract Relax Stretching.The purpose of this study was to determine the effect of Infra Red (IR), Ultrasound (US), Myofascial Release and Contract Relax Stretching on the condition of Myofascial Syndrome Upper Trapezius.

Abstract

Turmeric (Curcuma longa) is a medicinal plant from the Zingiberaceae family which has the potential to be developed as a superior plant that has benefits and efficacy as a medicinal ingredient. Turmeric has a yellow dye called curcuminoids as much as 5% (50-60% curcumin, demethoxycurcumin and bisdemethoxycurcumin). The very basic content of turmeric is Curcuma or curcumin because it has the largest component. The purpose of this study was to determine the phytochemical content by conducting a screening test on the ethyl acetate fraction of turmeric rhizome using the TLC method and UV-Vis Spectrophotometry. This research method used descriptive method by means of observation or non-experimental. Phytochemical screening included tests for flavonoids, alkaloids, saponins, phenols, tannins and steroids/triterpenoids which carried out to determine the class of compounds contained in turmeric rhizome. The ethyl acetate fraction in turmeric rhizome suspected to contain curcumin, so a test for the levels of curcumin contained in turmeric rhizome was carried out. The results showed that the positive turmeric rhizome samples contained flavonoids, tannins, phenols and steroids. As well as negatively contain alkaloid compounds and saponins. The results of identification with TLC samples containing curcumin compounds according to the literature and the standard Rf value of curcumin is 0.75-0.80. The assay results using the UV-Vis Spectrophotometry method for the ethyl acetate fraction of turmeric rhizome samples yielded an average concentration of 159.79 mg⁄g.

Saat proses peradilan anak yang berkonflik dengan hukum (pelaku anak) dituntut oleh jaksa penuntut umum untuk melakukan restitusi dengan pidana penjara lebih ringan dari yang seharusnya. Sebagaimana yang kita tahu bahwa dalam system peradilan anak, anak yang berkonflik dengan hukum harus diadili dengan keadilan yang bertujuan pada restorative sebagaimana aturan yang disebutkan dalam Undang-Undang No 11 Tahun 2012 Tentang Sistem Peradilan Anak. Dan dengan pertimbangan hakim yang mengedepankan asas perlindungan anak, hakim memutuskan mengabulkan restitusi Sebagian (tidak sebesar tuntutan JPU) sebagia ganti kerugian atas kerugian dan penderitaan yang dialami oleh keluarga korban.
