Abstract

Di Indonesia, Tempe merupakan salah satu makanan yang disukai oleh masyarakat. Bahan baku pembuatan tempe berasal dari kedelai maupun non kedelai. Usaha pembuatan tempe di Indonesia banyak dilakukan di industri rumahan atau home industry, salah satunya adalah di Industri Pembuatan Tempe di Candiwesi, Kelurahan Bugel, Kecamatan Sidorejo Salatiga. Penelitian ini bertujuan untuk mengetahui tata cara pembuatan tempe kedelai (Glycine max (L.) Merr) dan kacang merah (Phaseolus vulgaris L.) berdasarkan contoh prosedur dari home industry pembuatan tempe di Candiwesi, Salatiga, serta memberikan pembahasan mengenai fungsi dari tiap perlakuan pada proses pembuatan tempe. Artikel ini juga merupakan luaran penelitian dalam rangka KKL (Kuliah Kerja Lapangan) mahasiswa Biologi UIN Walisongo Semarang di Candiwesi, Salatiga. Hasil penelitian menunjukkan bahwa proses pembuatan tempe berbahan dasar kedelai di Home Industry Candiwesi, Salatiga memiliki prosedur yang dapat diterapkan pada bahan baku kacang merah sebagai alternatif kedelai. Hasil produk tempe berbahan dasar kedelai dan kacang merah dibandingkan secara morfologi dan terdapat persamaan serta perbedaan kualitas tempe dengan kedua bahan baku tersebut. Berdasarkan durasi fermentasi, diketahui bahwa lamanya fermentasi tempe kedelai lebih cepat dibanding dengan tempe kacang merah. Dari hasil pengamatan, dapat disimpulkan bahwa tempe kacang merah (Phaseolus vulgaris L.) memiliki potensi sebagai alternatif untuk tempe berbahan dasar kedelai (Glycine max (L.) Merr).

Abstract

Nitrogen does not directly have advantages in human physiology system, but it holds one of the most critical roles in plants’ life cycle and productivity. Even though Nitrogen is the most abundant elements in the atmosphere, it is also the most deficient essential nutrients in plants. The proposed idea of the nitrogen-fixing GM crops, particularly wheat, is aimed to overcome those stated cons of the traditional diculture and nitrogen fertilizer. This analysis focus on the overview as well as the pro and cons of the genetically modified nitrogen-fixing plants in providing a better agricultural method. The genetically modifying method to generate a nitrogen-fixing non-legumes carries a significant chance of failure results and hindrance. The multilevel implication occurs when we need to modify the plants that not normally produce nodules in their roots to form the nodules and to modify the Nitrogen-fixing microbes to live in the nodules of non-legumes, which are not their natural dwelling places.In conclusion, the genetically modified crops project to fix their Nitrogen is feasible, but the difficulties and the funds needed still outweigh the benefits obtained in the future. With all of those limitations, the target goal to erase famine in 2050 just by funding the nitrogen-fixing wheat alone seems to be too high to be reached. The funds and efforts should be better spent on other factors and farming methods.

Abstract

Variation of land use can affect the quality of groundwater and increase the potential for groundwater contamination. Physical environmental conditions that have a low sensitivity to contamination of groundwater, but the use of land which could potentially generate pollutants, such as industrial areas, residential, the agricultural activity can increase the risk level of contamination in the groundwater in the area. The purpose of this study is to develop a groundwater risk to contamination map in the shallow aquifer and to determine priority areas of groundwater quality monitoring in Salatiga Groundwater Basin. Groundwater risk to contamination map was prepared on aspects of land use and the degree of vulnerability of groundwater to contamination using DRASTIC methods and spatially was prepared by using Geographic Information System. Results of the assessment of risk levels obtained worth the risk index 93-204. The risk index values are grouped into five (5) classes of risk: low, low to medium, medium, medium-high, and high. The output of this research can be input for local governments in understanding the possible spread of groundwater contamination as well as choosing the right strategy for the conservation of groundwater resources in the Groundwater Basin of Salatiga.

Abstract

Since the last five years of the COVID-19 outbreak, radiological images, such as CT-Scan and Chest X-Ray (CXR), have become essential in diagnosing this disease. However, limited access to facilities such as CT-Scanners and RT-PCR makes CXR images the primary method for COVID-19 testing. This research aims to improve the accuracy of CXR images in identifying COVID-19 patients based on the texture features: histogram and Gray Level Co-occurrence Matrix (GLCM), using the K-Means Clustering method. This study utilized 150 CXR images, including 75 COVID-19 patients confirmed by RT-PCR tests, and 75 patients with negative cases. The method used were consisted of pre-processing, and texture feature extraction with the seven most influential attributes based on gained information (histogram: standard deviation, entropy, skewness, kurtosis, and GLCM: correlation, energy, homogeneity), as well as classification using K-Means clustering methods. The results showed that the classification’s accuracy, sensitivity, and specification are 92%, 91%, and 93%, respectively. This image processing technique is a promising as well as a complementary tool in diagnosing COVID-19 cases, based on CXR images with lower costs and more reliable results.

Abstract

Many valuable cultural and religious heritage materials suffer from the process of biodeterioration and biodegradation, such as by the contamination of microbes—these contaminations affect the quality of the material as well as the health of the surrounding people. Several studies have been conducted to study the impacting entities as well as to overcome the biodeterioration and biodegradation problems. This review provides a fundamental definition of the said phenomenon and elaborates on the actions done by previous researchers with several approaches to identify and hinder future decay. This literature study compiles and selects previous studies to reach a conclusion. Fungi and bacteria are the two main classes of microorganisms responsible for biodegradation. Both of those organisms have the potential to degrade and deteriorate various types of cultural and religious heritage. The riskiest contamination for paper or manuscripts is brought on by fungi because of their capacity to degrade wood-based products. Additionally, the said microorganisms can have an impact on the health of those who are in close proximity to them, like librarians. The microbes have been studied, identified, and their growth has been prevented using various techniques. More research is still required to avoid the biodegradation and biodeterioration of the priceless cultural and religious heritage, as well as to develop techniques that are both effective and environmentally safe.

Abstract

This research is one of the efforts and the first step in the preservation of historical ancient manuscripts with an interdisciplinary scientific approach. The Unity of Sciences involved in this research are historical science, archaeology, philology combined with natural sciences such as microbiology and biotechnology approaches. The ancient manuscript whose microorganisms were isolated and observed in this study is an ancient manuscript with Pegon letters titled "Layang Watu Gunung" which dates from the 19th century. Over time, microorganisms can contaminate the paper on the manuscript which can cause damage or biodeterioration. Efforts to preserve historical manuscripts can be started by identifying in advance what types of microorganisms are contaminating the manuscript. From the results of the study, it was found that the microorganisms that contaminate the Layang Watu Gunung Ancient Manuscript are types of bacteria and fungi. For bacteria, the results of the Gram staining test result for contaminant bacteria are Gram Negative Bacteria. This initial research will be the basis for further preservation efforts, the results will be more relevant to be analyzed, especially for other historical manuscripts that are in similar temperature and humidity conditions, namely on the island of Java.
