Abstract

Indonesia is one of 22 countries with a high incidence of tuberculosis in the world, particularly related to TBHIV and MDR-TB cases. Contamination of normal flora from nasopharyngeal tract is the main problem to isolate Mycobacterium tuberculosis (MTB) from sputum. Therefore, a safe solution to decontaminate sputum without killing MTB bacilli is needed. N-acetyl-L-cysteine-sodium hydroxide (NALC-NaOH)-based method and Petroff's method, which was modified with NaOH (4%) are widely used in laboratories. In the present study, we will evaluate the different of these methods. Of the 110 sputum samples were collected from suspected cases of Pulmonary TB, and the decontamination of sputum by these methods was performed, after acid-fast bacillus (AFB) smear, then the samples were cultured in Lowensteins Jensen slant medium. The positive culture was validated by chromatography test for detecting the antigen of MPT-64 and PNB. Based on the investigation, it has been shown that neither NALC-NaOH (71%) nor modified Petroff's methods (66%) had a significant effect on the positivity rate of AFB smear. However, the contamination on culture was significantly higher in samples treated with NALC-NaOH (21%) compared to Modified Petroff methods (13%) (p< 0.05). In addition, the proportion of positive culture in NALC-NaOH was lower than modified Petroff. In conclusion, our study proved that modified Petroff methods are still more effective on sputum decontamination than NALC-NaOH based on the positivity rate of MTB culture. Though, not significantly different on AFB microscopic examination.

Abstract

This study aims to determine and analyze the effect of partially and simultaneously between workload and work facilities on the work effectiveness of production employees at PT Wieda Sejahtera. This study includes causal associative research with a quantitative approach and a population of 30 workers with a sample calculation using a saturated sampling technique. The number of samples used in this study were 30 respondents. Testing the instrument using validity and reliability tests. While the data analysis method used multiple linear regression analysis, the coefficient of determination R2 test, T test, and F test. Data processing in this study was carried out using SPSS 22 software for windows. The regression equation model Y= 50,997 - 0,464 (X1) + 0,542 (X2) + is feasible to use. Based on the partial correlation results, the workload variable (X1) has an effect on work effectiveness (Y) of 10.96 percent, while the work failure variable (X2) has an effect on work effectiveness (Y) of 12.89 percent. Based on the results of the analysis of the coefficient of determination (R2) of 29.3 percent work effectiveness is influenced by workload and work facilities while the remaining 70.7 percent is influenced by other variables not discussed in this study such as motivation, work stress, leadership style and so on.

Abstract

One of the most important sources of natural light for life is sunlight, and the skin is the outermost and most significant organ in the human body, making it vulnerable to sunlight exposure. This study aims to determine the biochemistry of secondary metabolite compounds in the guava tangkalak leaves of the plant and their activities as an active ingredient of sunscreen using UV-Vis spectrophotometry. The results of this study indicate that the guava tangkalak leaves plant contains secondary metabolite compounds, such as flavonoids, alkaloids, tannins, saponins, and steroids. The SPF values produced at concentrations of 400, 500, 600, 700, 800, and 1000ppm, SPF values of 2.96, 4.60, 7.70, 10.76, 15.13, and 27.41. The maximum concentration of 1000 ppm protects ultra-categories in SPF.
ANALISIS HAK WARIS PEREMPUAN DALAM HUKUM ISLAM (STUDI PEMIKIRAN MUHAMMAD SYAHRUR DAN PROYEKSINYA DALAM KONTEKS ADAT MATRILINEAL DI MINANGKABAU) Haliza Kanaya Rizky; Muhammad Rayhan; Silvia Anggriyani Agustina

Abstract

Hukum waris Islam di Indonesia memiliki peran penting dalam kehidupan masyarakat Muslim. Prinsip-prinsip syariat yang mengatur pembagian warisan berdasarkan Surah An-Nisa ayat 11 menetapkan bahwa bagian laki-laki adalah dua kali lipat dari bagian perempuan. Muhammad Syahrur, pemikir kontemporer, menawarkan pendekatan pembaruan hukum waris melalui teori batas maksimal dan minimal serta metode ijtihad insya’i. Syahrur berpendapat bahwa pembagian warisan bersifat fleksibel dan dapat disesuaikan dengan realitas sosial, ekonomi, dan budaya. Dalam konteks Indonesia, dualisme antara hukum Islam dan budaya lokal, seperti sistem matrilineal Minangkabau, menciptakan ketegangan yang memerlukan solusi kontekstual. Integrasi hukum Islam dengan adat lokal melalui pendekatan dialogis dapat menciptakan sistem waris yang lebih adil dan responsif. Evaluasi sistem hukum waris Islam tidak dimaksudkan untuk menghilangkan esensi syariat, tetapi untuk memastikan relevansinya dalam menjawab dinamika kehidupan modern, termasuk peran perempuan yang semakin signifikan. Dengan demikian, harmonisasi hukum waris Islam dan budaya lokal dapat menjadi instrumen keadilan yang berkelanjutan.

Abstract

This research objective aims to explore the effects of gamification in improving students' English writing skills. Many students face challenges in developing this skill due to limited vocabulary and difficulties with grammar. The study focused on 10th-grade high school students using a quasi-experimental design with a quantitative approach . Data were collected by using pre-test and post-test assessments of recount text writing. The quality of writing was evaluated using criteria such as content, organization, vocabulary, grammar, and mechanics, based on Heaton's (1988) framework. Findings indicated that the experimental group, which utilized gamification, achieved a better mean score (28.22) compared to the control group (24.64). However, Mann-Whitney test results indicate there is no statistically significant difference between the groups (p = 0.393 > 0.05). This implies that while gamification shows potential in improving grammatical accuracy and vocabulary in writing, its impact remains statistically insignificant. The study suggests that for gamification to be more effective in writing instruction, it may require a longer implementation period, better calibration of task difficulty, and an enhanced feedback system targeting grammar and vocabulary development.

Abstract

Aedes Aegypti is the cause of Dengue Hemorrhagic Fever (DHF), which is transmitted by its bite. Schools are one of the locations that cause the transmission and spread of dengue fever due to the cleanliness of the school environment and school sanitation, which is still classified as not yet clean. This community service aims to educate students on preventing the spread of dengue hemorrhagic fever by implementing clean and healthy living behavior in the school environment. Community service methods include socialization, pre-test, and post-test, student education using lecture methods, and discussions with students. The community service results stated that there was an increase in the knowledge of students at SMPN 191 West Jakarta in understanding the implementation of PHBS in the school environment as an initial effort to prevent the spread of dengue fever in the school environment. In this activity, information was obtained that 79.95% of students' knowledge had increased regarding the application of PHBS, especially in washing hands using soap. However, several points that were not optimal were consuming healthy food in the school canteen area.

Abstract

Penelitian ini bertujuan untuk menganalisis strategi komunikasi digital yang diterapkan oleh Badan Eksekutif Mahasiswa (DEMA) IAIN Bone dalam membentuk citra organisasi di era digital. Metode penelitian yang digunakan adalah pendekatan kualitatif deskriptif dengan desain studi kasus tunggal. Informan penelitian terdiri dari tiga orang pengurus DEMA dan satu orang mahasiswa penerima komunikasi organisasi yang dipilih melalui teknik purposive sampling. Teknik pengumpulan data dilakukan melalui wawancara semi terstruktur melalui WhatsApp dan observasi aktivitas media sosial resmi DEMA, seperti Instagram, TikTok, Facebook, dan YouTube. Hasil penelitian menunjukkan bahwa DEMA menerapkan strategi komunikasi digital melalui konten visual, penyampaian informasi yang cepat, dan koordinasi internal berbasis diskusi kolektif. Citra organisasi dipersepsikan positif sebagai lembaga yang representatif, aktif, dan responsif terhadap isu-isu kemahasiswaan. Namun demikian, masih ditemukan keterbatasan pada aspek evaluasi formal dan pelatihan digital bagi pengurus. Implikasi dari penelitian ini menekankan pentingnya strategi komunikasi partisipatif, penguatan evaluasi berbasis data media, dan pemanfaatan kanal digital yang optimal untuk membangun citra organisasi kemahasiswaan yang berkelanjutan.
