Analisis Produksi Biogas Berdasarkan Bahan Baku Limbah Kotoran Sapi, Serbuk Gergaji, dan Effective Microorganisme-4 (EM4)
Authors: Adrianto Mario Dwi
Published: September 2019

Biogas is an alternative energy made from organic waste. Organic waste which is often used as raw material for biogas is cow dung. Cow manure is used as raw material for biogas because the cellulose content in it is quite high and its availability is relatively large. However, if only one material is used, the optimum C / N ratio will not be achieved. If the optimum C / N ratio is achieved, the gas produced in biogas production will also increase. One way to get the optimum C / N ratio is by adding biogas filling material. In this study, variations in the composition of biogas filling materials were carried out, namely (1) cow dung, (2) cow dung and sawdust, and (3) cow dung, sawdust, and EM4. Of the three variations of this filling material, measurements of temperature, gas pressure, and pH will be carried out. The purpose of this study was to determine the effect of the composition of the biogas mixture on the variables of temperature, gas pressure, and pH. The biogas production process were divided into several stages, such as mixing filling material, inputting filling material into the digester, fermentation process, taking the data of observation, and analyzing the data. The results showed that differences in the composition of biogas raw materials affected the variable temperature and gas pressure. As for pH, the composition of the filling material does not have a significant effect.

Published: September 2019

Background: Extranodal lymphoma appears in about 40% of all lymphoma patients and has been reported in almost all tissue and organs. The most common site is the intestinal tract, followed by head and neck. There are many reports about extranodal lymphomas that arise in orbits, paranasal sinus and oral cavities, nasal, thyroid and salivary glands. These lymphomas usually do not destroy adjacent bone, unlike squamous cell carcinoma. Case: We would like to present an uncommon case of diffuse large B-cell extranodal lymphoma arising maxillofacial bone on buccal area that infiltrating to maxillary sinus and orbital, with bone destruction as well. The patient responded well with CEOP regimen chemotherapy and showed significant tumor regression with symptoms reduction. She just underwent the seventh series of chemotherapy now and planned to be restaging after eighth chemotherapy. Conclusion: Chemotherapy remains the treatment of choice for non-Hodgkin lymphomas. Surgery also takes place in modality choice of treatment of maxillary cancer, either a partial or total maxillectomy alone, or maxillectomy with craniofacial resection.

Published: September 2019

Background: Benign breast disease have been broadly classified into non-proliferative lesions, proliferative lesions without atypia and hyperplasia with atypia. Proliferative disease, such as usual ductal hyperplasia, is associated with a 1.5 to 2 fold increased risk of developing invasive carcinoma. We reported a case of usual ductal hyperplasia in a young male. Case: A 22-year-old male complained of discomfort and enlargement of unilateral breast. Physical examination at that time revealed a palpable mass in the lateral upper quadrant of the patient’s left breast, three centimeters from nipple areola complex. The examination of axilla didn’t reveal any lymph node enlargement on both sides. His vital signs were normal without any abnormalities found on examination. Ultrasonography examination demonstrated fibroglandular tissue in the left breast with the volume of 11.13 cm3, consist of 4.8 cm length, 2.9 cm width and 0.8 cm depth. Excisional tumor biopsy was done on his left breast. Usual duct cell hyperplasia was present in microscopic examination with chronic inflammatory cells spreading around the fibrotic stromal cell. Physical examination, radiologic examination, and biopsy were all performed in this patient. Although the accuracy of the triple test is high, benign concordant results do not obviate further surveillance of a palpable mass. We advised our patient to routinely follow-up his condition every 6 months for 1 to 2 years, especially if there any changes found on his breasts. Conclusion: Any guidelines and further studies regarding patient’s follow-up examination after biopsy for male breasts tumor are needed in order of better understanding about this disease.

Darkening of the skin results from excessive production of melanin in the skin caused by an increase in tyrosinase related protein 1 enzyme activity. Catechins are flavonoid compounds which contain antioxidants. This study aims to determine the affinity and mechanism of catechins as skin lightening agents by inhibiting tyrosinase related protein 1 target proteins in silico using molecular docking methods. The study was carried out exploratively with the stages of preparing a database of 3D structures of catechins and tyrosinase related protein 1, optimization of 3D structure of catechins, protein preparation, validation of molecular docking methods, and docking of catechins in tyrosinase related protein 1. Docking results are assessed from the bonding energy and hydrogen bonds formed between catechins and proteins. The smaller the bond energy value, the stronger the bond between the catechins and proteins. The results showed that catechins had activity as skin lightening agents because they were able to inhibit the tyrosinase related protein 1 with a bond energy value of -6,35 Kcal/mol. The energy value of the catechin bond with the tyrosinase related protein 1 is smaller than the tyrosinase related protein 1 with its native ligand. This shows that catechins have greater potential and affinity in inhibiting the tyrosinase related protein 1 enzyme with hydrogen bonds on amino acid residues, namely ARG374. Based on the results obtained, catechins have activity as skin lightening agents with the mechanism of inhibiting the tyrosinase related protein 1 enzyme so that the amount of eumelanin formed is less and the skin becomes brighter.

Riset ini bertujuan menggali tafsir budaya(wan) Madura terhadap multitafsir dari aparatur sehubungan dengan mekanisme “Dana Taktis” dalam pengelolaan keuangan pemerintah daerah pada temuan riset Setiawan, Irianto dan Achsin (2013) yang terejawantah dalam kalimat temuan system-driven (un)fraud. Berbasis metodologi bid’ah hermeneutics, sebuah bentuk perluasan dari hermeneutika, multitafsir dari pengelola keuangan daerah dicarikan tafsir dari nilai budaya Madura sebagai salah satu pegangan nilai yang dipegang kuat masyarakat pada situs di mana riset Setiawan, Irianto dan Achsin (2013) dilakukan. Nilai budaya dalam penelitian ini digali dari budayawan Madura terpilih yang juga memahami persoalan “Dana Taktis” ini. Riset ini menyimpulkan bahwa nilai kejujuran tidak memperkenankan adanya “penyiasatan” dalam bentuk apapun. Kejujuran adalah sendi nilai yang harusnya mewarnai segala hal ikhwal kehidupan, termasuk dalam pengelolaan keuangan daerah. Tafsir baru atas konsep “malo” dan penegakan budaya kejujuran adalah hal penting yang harus diajukan sebagai solusi jangka panjang secara kebudayaan guna mengeliminasi praktik nir-kejujuran
