Abstract

Microscopic examination of sputum using the Ziehl-Neelsen stain is the gold standard for Tuberculosis (TB), but it must be performed by experts with special skills. The purpose of this study is to accelerate the determination of the microscopic results using the Ziehl-Neelsen stain. This research is an experimental method in which the test sample is treated and the sputum sample is controlled with up to 25 samples. The method development is very important to increase the sensitivity and specificity of the results of TB examination using microscopes. This observation shows that the indirect cytospin method has a narrower reading range on a circle with a diameter of only 7 mm, making it easier for a bacterial count compared to the traditional direct method with a size of 2 x 3 cm oval shape. The results of the microscopic examination were 21 positive specimens and 4 negative specimens. Mycobacterium tuberculosis with Ziehl-Neelsen staining gave the same results with a sensitivity and specificity of 100%.

Abstract

Telah dilakukan penelitian pengaruh Cr(VI) dan Cr(III) terhadap pertumbuhan fitoplankton berdasarkan pengukuran kerapatan sel dan peningkatan konsentrasi klorofil. Fitolankton dikultur dalam media yang diberi nutrien dan mengandung Cr(VI) atau Cr(III) dengan konsentrasi bervariasi. Kerapatan sel dan konsentrasi klorofil ditentukan pada waktu kultur 16, 24, 32, 40, 48, 56 jam. Konsentrasi klorofil ditentukan secara spektrofotometri. Kerapatan sel dihitung menggunakan haemocytometer dengan pengamatan di bawah mikroskop. Hasil penelitian menunjukkan bahwa Cr(VI) dan Cr(III) menghambat laju pertumbuhan fitoplankton. Besarnya hambatan laju pertumbuhan sebanding dengan besarnya konsentrasi Cr(VI) dan Cr(III) dalam media kultur. Secara kuantitatif diperoleh harga EC50 Cr(VI) dan Cr(III) terhadap laju pertumbuhan fitoplankton berdasarkan kerapatan sel, masing-masing sebesar 0,0005 dan 0,0014 ppm, sedangkan berdasarkan konsentrasi klorofil, masing-masing sebesar 0,0012 dan 0,0056 ppm. Hal ini mengindikasikan bahwa Cr(VI) lebih toksik daripada Cr(III) terhadap pertumbuhan fitoplankton. Hal ini mengindikasikan bahwa penggunaan kerapatan sel sebagai parameter pertumbuhan fitoplankton yang dipengaruhi Cr(VI) dan Cr(III) memiliki sensitivitas yang lebih baik daripada penggunaan parameter peningkatan konsentrasi klorofil. Kata Kunci : Konsentrasi klorofil, kerapatan sel, Fitoplankton, Cr(VI), Cr(III).

Abstract

Endospores are formed by members of several genera of gram-positive bacteria, such as Bacillus and Clostridium. The spores are very resistant structurally; withstand the temperature of boiling water for two hours or more. They contain very little water and show very few chemical reactions. The favorable external environment will cause the spores to break down and the vegetative cells to appear to grow and reproduce. Identification of endospore-forming pathogens is important in food and medical microbiology. However, the spores contain multiple protective layers, which cannot be easily penetrated by simple staining or Gram staining techniques. Therefore, it is necessary to apply heat to help penetrate the color, with various methods of Gram stain, fluorescent spore painting, Schaeffer and Fulton spore painting and Client's spore painting method. The results of the fluorescent painting method have better results but require much more expensive equipment using a fluorescent microscope considering the facilities that must be provided for the Schaeffer and Fulton painting method as an alternative if they do not have these facilities.

Abstract

Blood donation is a humanitarian activity where someone donates blood voluntarily. Blood Donation Units are required to provide safe and quality blood products to avoid transfusion reactions. One effort that can be made is to carry out pre-transfusion examinations on donor blood, one of which is an antibody screening examination. The aim of the antibody screening examination is to detect the presence or absence of clinically significant irregular antibodies in both the patient and donor. The aim of this study was to determine the blood type, gender and age of antibody screening in voluntary blood donors at the Blood Donation Unit. This type of research is descriptive using observational methods which was carried out in March 2023 at the Banyumas Regency Blood Donation Unit. Samples were taken using a total sampling technique, namely all voluntary blood donors who underwent an antibody screening test. Data collection was carried out using the qwalist diagast tool and laboratory archives which were accessed via the SIMDONDAR system. The results of the antibody screening research from a total of 3198 voluntary blood donors showed that the highest results were in blood type O, namely 1236 (39%) donors, in men, namely 2196 (69%), and in the elderly (26).-60 years).namely 1531 (48%) donors

Abstract

Pertumbuhan penduduk Indonesia berkembang dengan pesat sehingga menyebabkan kebutuhan rumah tempat tinggal dan gedung lainnya akan semakin meningkat sesuai dengan keinginan dan kebutuhan manusia. Untuk mengurangi ketergantungan akibat keterbatasan material bangunan telah mendorong dunia konstruksi untuk melakukan peningkatan teknologi baru tentang bahan bangunan, seperti pengembangan teknologi material bangunan seperti bata ringan Cellular Light-weight Concrete (CLC) sebagai salah satu alternatif untuk menggantikan bata merah. Keuntungannya adalah bata ini lebih untuk dinding. Pengujian pemaparan suhu tinggi telah dilakukan pada beton namun penelitian bata ringan terpapar suhu tinggi belum banyak dilakukan oleh peneliti. Penelitian ini dilakukan dengan tujuan untuk menganalisis dan membandingkan sifat mekanik dan fisik CLC serta kuat tekan pada saat sebelum dan sesudah terpapar suhu tinggi dengan ukuran bata ringan tinggi 20 cm lebar 10 cm dan panjang 60 cm serta komposisi campuran semen berbanding pasir sebesar  1:1, 1:2 dan 2:3 dengan usia sampel 28 hari. Analisis rambatan panas dilakukan menggunakan perangkat lunak LUSAS V19 dengan suhu paparan 100° C dan 200° C selama 30 dan 60 menit. Berdasarkan pengujian bata ringan setelah pemaparan suhu tinggi selama 60 menit, kuat tekan bata ringan ukuran kubus pada campuran semen berbanding pasir 1:1 mengalami penurunan kuat tekan sebesar 58.09% dibandingkan sebelum terpapar sedangkan bata ringan ukuran balok mengalami penurunan kuat tekan sebesar 37,77% dibandingkan sebelum terpapar. Selain penurunan kuat tekan, hasil penelitian ini juga menyimpulkan bahwa pemaparan suhu tinggi telah menyebabkan perubahan pada bata ringan seperti perubahan warna, perubahan ukuran lobang pori serta perubahan kuat tekan. Dengan demikian hasil penelitian ini dapat dijadikan referensi bagi praktisi terkait perbedaan sifat mekanik.

Abstract

Sebagai umat Islam, perintah untuk menunaikan zakat, infaq, dan sedekah merupakan bagian dari ibadah yang memiliki dampak sosial besar. Namun, dalam kenyataannya, masih banyak umat Muslim yang enggan menunaikan kewajiban ini. Kajian ini bertujuan untuk memahami faktor-faktor yang mempengaruhi kecenderungan mukallaf dalam menunaikan kewajiban zakat serta praktik infaq dan sedekah di wilayah kecamatan Cempaga. Penelitian ini menggunakan pendekatan kualitatif deskriptif-evaluatif dengan menganalisis, menyajikan, dan menilai data secara analitik-argumentatif. Penilaian didukung teori untuk verifikasi dan justifikasi, kemudian disimpulkan secara jelas dan rinci. Hasil penelitian menunjukkan pemahaman masyarakat tentang zakat, infaq, dan sedekah masih terbatas akibat minimnya edukasi dan sosialisasi. Faktor seperti sifat materialistis, ketidakpercayaan terhadap pengelolaan dana, serta lemahnya kesadaran spiritual turut memengaruhi kepatuhan berzakat. Selain itu, gaya hidup konsumtif dan kurangnya edukasi dari tokoh masyarakat memperburuk kebiasaan berbagi. Oleh karena itu, diperlukan peran aktif lembaga zakat, pemerintah, dan tokoh agama dalam meningkatkan edukasi, transparansi, serta kesadaran sosial dan spiritual.   As Muslims, the command to give zakat, infaq, and sadaqah is a form of worship that carries significant social impact. However, in reality, many Muslims are still reluctant to fulfill this obligation. This study aims to understand the factors that influence the tendency of mukallaf (those obligated by Islamic law) in fulfilling the obligation of zakat, as well as the practice of infaq and sadaqah in the Cempaga sub-district. The research uses a descriptive-evaluative qualitative approach by analyzing, presenting, and assessing data in an analytical-argumentative manner. The evaluation is supported by theory for verification and justification, followed by clear and detailed conclusions. The findings show that public understanding of zakat, infaq, and sadaqah remains limited due to a lack of education and outreach. Factors such as materialistic attitudes, distrust in fund management, and weak spiritual awareness affect compliance with zakat obligations. Additionally, a consumptive lifestyle and the lack of education from community leaders worsen the habit of giving. Therefore, the active role of zakat institutions, the government, and religious figures is needed to enhance education, transparency, and social and spiritual awareness.
