Abstract

Tujuan penelitian ini adalah untuk mengetahui dampak penggunaan whey dalam substrat biogas terhadap rata-rata produksi metan, kecernaan bahan organik (KcBO) dan pH slurry. Rancangan percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan 2 perlakuan yaitu Tdengan bahan isian feses sapi Madura dicairkan dengan air (FA) dan T2 1dengan bahan isian feses sapi Madura dicairkan dengan whey (FW) dengan perbandingan 1:1. Ulangan yang dilakukan berupa pengambilan data selama 2 kali hydraulic retention time. Analisis data menggunakan t-test. Hasil penelitian menunjukkan bahwa terdapat perbedaan nyata (P<0,05) dari perlakuanpenggunaan whey terhadap produksi metan. FW menunjukkan produksi metan yang lebih besar dibandingkan dengan FA (1465 vs 613 ml/l volume digester aktif), untuk KcBO antara FA dan FW (31,53% vs 37,45%) dan pH slurry antara FA dan FW (6,86 vs 6,88) menunjukan hasil tidak berbeda nyata (P>0,05). Whey berpotensi untuk digunakan sebagai bahan pencair feses sapi Madura pada pembuatan biogas untuk mengoptimalkan produksi metan. Kata kunci : feses, KcBO, metan, pH, whey

Abstract

The purpose of this study was to investigate the effect of inoculum to substrate (I/S) and carbon to nitrogen (C/N) ratios on the biogas quantity and quality from anaerobic digestion of Salvinia molesta (SM). The I/S was adjusted to become 1.5, 2, 2.5 and the C/N was to become 21.5, 25, 30. Anaerobic digestion (AD) was operated during 30 days under the room pressure and temperature. The results showed that increase in I/S from 1.5 to 2.5 increased the biogas yield from 19.01 to 33.84 mL/g VS. Besides that, it increased the methane content from 52.54 to 69.01%. Furthermore, increase in C/N to 21.5 to 30 decreased the biogas yield from 33.84 to 30.85 mL/g VS and then decreased the methane content from 69.01 to 6.99%. Hence, the best condition was in the substrate with I/S of 2.5 and C/N of 21.5. The measured data was successfully predicted through the modified Gompertz and the first order kinetic models with R2 of 0.9905 and 0.9476 respectively.

Abstract

Background: Hand Foot and Mouth Disease (HFMD) is caused by the Coxsackie's and enteroviruses. The disease has spread out in South East Asia. There was no report of this disease inYogyakarta until 2000. This was the first report of HFMD in Yogyakarta. Methods: During 8 months from May 1, 2001 to December 31, 2001, 42 cases were examined in a private practice.Results: There were 42 cases of the disease during 8 months. The highest number of cases (21 cases) was found in July 2001. Mostly cases were found in children under 5 years old especially in those 13-24 months of age. The ratio between boys and girls was 3:2. The clinical manifestations included fever about 1-3 days, enanthem, exan-them, vesicle, and ulcer in hands, foot, and nausea.Conclusions: All of the cases can be cured by symptomatic treatment and there is no complication of the disease. It is important for Yogyakarta special province to keep far from the disease by the prevention program. Keywords: HFMD, enterovirus, children

Abstract

The study aims to evaluate the adoption of the Coretax system by government expenditure treasurers using the Technology Acceptance Model (TAM). We assesses the factors influencing users' attitudes and intentions toward using new technology. Primary data from local government public service agencies in Karanganyar and Wonogiri regencies are collected by using questionnaire, analyzed with linear regression and path analysis. Our analysis reveals that perceived usefulness and behavioral intention are scored high, indicating that the treasurers find Coretax beneficial and are strongly inclined to continue using it. However, perceived ease of use and attitude toward use showed moderate to high ratings, indicating room for improvement in terms of ease of use and user comfort. Regression analysis found that perceived ease of use significantly affects perceived usefulness, attitude toward use, and behavioral intention. However, perceived usefulness and attitude toward use did not significantly influence behavioral intention. The findings suggest that the ease of use of Coretax plays a more crucial role in shaping the treasurers' behavioral intentions than perceived usefulness or affective attitude. This study providing insights into key determinants affecting user intentions and offering empirical foundations for developing training policies, system design improvements, and implementation strategies tailored to the public sector's needs. The findings of this research are also expected to contribute to offer practical implications for strengthening national tax digitalization reforms.
