Abstract

Squid is one of the fisheries commodities that is quite important and ranks in the third position after fish and shrimp. Still, many people don't know that these animals have bones that usually discarded when processing squid meat. Squid pens used as a source of medicinal ingredients, one of which is chitosan. Chitin was obtained by deproteination process with 3.5% (w/v) NaOH, and demineralization with 1 M HCl. Chitosan was obtained from the chitin deacetylation process using a variation of 50% (w/v) NaOH and 60% (w/v) NaOH. In this research, chitosan only produced use method 60% acetylation degree. Chitosan compounds obtained from the deacetylation process, with 60% NaOH were analyzed using FTIR spectrophotometers, received functional groups: C-H, O-H, N-H, and NH2.

Abstract

Coal-mining mud is one of the wastes that must be treated before being discharged into the environment. The mud contains a lot of heavy metals which have the potential to pollute the environment and endanger human health. On the other hand, the metal contents in the mud can be used as components to strengthen building materials such as brick. In this study, an investigation was carried out to check whether the risk of heavy metal contamination in the coal-mining mud can be minimized when the brick is produced. In addition, this study also tested whether the bricks produced from the utilization of the mud were strong enough to be used as construction materials. The results obtained indicate that metal contamination can be significantly minimized through the solidification process of brick products and is following the Indonesian national quality standards. This study also shows that even though the bricks meet the strength standard for the certain purpose applied in Indonesia, the utilization of coal-mining mud mixed with cement and sand was not sufficient to produce strong bricks even though the weight obtained was quite light.

Abstract

The background of this study is based on the phenomenon of low performance of honorary employees which is allegedly influenced by lack of compensation and unbalanced workload. This study aims to analyze the effect of compensation and workload on the performance of honorary employees with work motivation as an intervening variable in the Solok City Regional Secretariat. This study uses a quantitative method with a survey approach, where data is collected through the distribution of questionnaires to 103 honorary employees who are the research samples. The data analysis technique used is Structural Equation Modeling (SEM) to test the relationship between the research variables. The results of the study indicate that compensation has a positive and significant effect on work motivation and employee performance. In contrast, workload shows a negative influence on work motivation but is not significant on employee performance. Additionally, work motivation is proven to be a significant intervening variable in mediating the effect of compensation on the performance of honorary employees. This study implies that increasing compensation can enhance employee motivation and performance, while excessive workload may decrease work motivation

Abstract

Orange peel is one of the main sources of essential oil. Lemon orange can also be found in an area of Jambi City, commonly referred to as local lemon, but the shape and characteristics differ slightly from common lemons. The identification results of local lemon peels indicate that these oranges are a cross between lemons and limes (Citrus medica × Citrus aurantifolia). This study aims to analyze and determine the differences in the components of the peels of lemon, local lemon, and lime using gas chromatography–mass spectrometer (GC-MS). The contribution of this research lies in providing scientific data on the chemical composition of local lemon peels, which have not been widely studied, thereby offering potential applications for the development of natural products, essential oil industries, and local biodiversity utilization. This research was conducted by extracting the peels from lemons, local lemons, and limes using acetone as a solvent. The extracts were then analyzed for their components using GC-MS. The GC-MS analysis of acetone extracts from lemon, local lemon, and lime peels revealed 19 compounds in each sample. Four compounds were found to be common across all three samples, namely 2-pentanone, 4-hydroxy-4-methyl; β-bisabolene; bis (2-ethylhexyl) phthalate; and 2H-1-Benzopyran-2-one, 5,7-dimethoxy. Meanwhile, 15 other compounds showed different contents, indicating that the hybrid nature of local lemons influenced their chemical composition. These findings highlight the unique characteristics of local lemon peels and their potential as a valuable source of bioactive compounds.

Abstract

Hypertension is also called the silent killer characterized by continuously high blood pressure in the ratio of systolic blood pressure (TDS) ≥ 140 mmHg and diastolic blood pressure (TDD) ≥ 90 mmHg. This hypertension requires long-term treatment, therefore patient non-compliance in therapy can cause failure of hypertension treatment. To determine the level of patient compliance in hypertension treatment, it can be seen from the compliance of drug retrieval by analyzing the relationship to gender, age, and comorbidities. This research method is carried out non-experimentally and uses analytical descriptive methods. Data collection from the poly registration book for patients with the July 2023 reverse referral program which will be measured 6 times from July - December 2023 obtaining patients with a population of 411 patients and a sample of 218 patients. The results showed that women suffered more from hypertension (62.8%), the most age of hypertension ≥60 years (78.4%), and patients suffered from hypertension without comorbidities (60.6%). The most commonly used hypertension treatment was monotherapy (56.9%). The level of compliance of hypertensive patients in the referral program was high in the category of re-taking antihypertensive drugs (67.4%). The results of the analysis stated that there was a relationship between gender and age on compliance with taking antihypertensive medication. The conclusion of this study is that the level of compliance is included in the high category, and there is a relationship between gender and age on compliance with re-taking antihypertensive drugs.
