Tinjauan Molekuler dan Epidemiologi Mutasi pada Virus SARS-CoV-2
Full text linkAbstract. The SARS-CoV-2 virus which is the cause of the COVID-19 pandemic since the end of 2019 has undergone many mutations that gave rise to several variants of concern (VOC) with higher transmission, virulence, and ability to evade the immune system than the initial variant (wild-type). Until now, there are four variants included in the VOC of the virus, namely alpha, beta, gamma and delta variants. The increased transmission and virulence of these VOCs were associated with mutational changes in the spike protein, which is the structure of the virus that plays a role in binding to host cells. In this article, we conduct a literature review on VOCs from the SARS-CoV-2 virus related to mutations that occur and their impact on the viral binding process. To gain an understanding of the impact of mutations in these variants, we also reviewed the structure of the spike protein and the process of viral entry into host cells. Keywords: viral mutation, variants of concern (VOC), COVID-19, SARS-CoV-2

Full text linkAbstract. This research aims at investigating the diversity of fish species contained in Air Jernih River Padang Guci Hulu District Kaur Regency Bengkulu Province. The method used in this research was the direct survey method to the research location. The sampling technique was conducted by dividing the station based on the characteristics of the river consisting of three locations, namely station A with the characteristics of the river that is rocky and mossy, the station B with the characteristics of the river that is rocks and pebbles (coral), and station C is with sandy river characteristics. From the research results, it can be revealed that the diversity of fish contained that the diversity contained in the three stations, having different fish diversity on station A with the index of diversity of 0.58, station B with the index of diversity of 0.57, and on station C with diversity index 0, 66. The types of fish contained in Air Jernih river of Padang Guci Hulu District Kaur Regency Bengkulu Province were containing 7 species belonging to 5 families. The fish species are: Gobiinae (Sicyopterus cynocephalus), Anabantidae (Anabas testudineus), Ciclidae (Oreochromis niloticus), Anguillidae (Anguilla marmorata), and Cyprinidae (Rasbora argyrotaenia, Barbonymus gonionotus and Osteochilus vittatus).Keywords: diversity, river fish air jerni

Evaluasi Rasio Netrofil Limfosit (RNL) untuk diagnosis COVID-19 pada Pasien di RS Tadjuddin Chalid, Makassar, Indonesia
Full text linkAbstract. The neutrophil lymphocyte ratio (NLR) is one of the variables related to the severity of COVID-19 disease. Therefore, we evaluated the value of NLR in COVID-19 patients and its relation to the symptoms and severity of COVID-19 at Tadjuddin Chalid Hospital, Makassar. We recruited patients visiting Tadjuddin Chalid Hospital Makassar who were willing to take part in the study in April to August 2021. Demographic, clinical and laboratory data were recorded through interviews and medical records. The severity of the disease is classified according to the guidelines from the association of Indonesian pulmonary doctors, Indonesian internal medicine doctors, Indonesian pediatricians, anesthesiologists and intensive care doctors, and the Indonesian cardiologist association. NLR data was obtained by calculating the ratio between neutrophil levels and lymphocyte levels in the blood. A total of 130 patients took part in the study, between 19-72 years old. There were 77 subjects (59.2%) with mild symptoms, 28 (21.6%) with moderate symptoms, and 25 (19.2%) with severe symptoms. There were 89 subjects with NLR 3.5. NLR values in patients with severe and moderate disease were significantly different from NLR in patients with mild disease (p =0.0002 dan p 3.5 can be used as an indicator for a suspected moderate or severe COVID-19 diagnosis.Keywords: COVID-19, neutrophil lymphocyte ratio (NLR), pneumonia, disease severity, diagnostic too
Periodisitas Tanaman Pekarangan Sebagai Database dalam Pengembangan Wisata Berbasis Konservasi Lingkungan di Desa Sajang, Kecamatan Sembalun, Lombok Timur
Full text linkAbstract. The purpose of this study was to determine the periodicity of fruit and vegetable and ornamental plants which can be used as a database in environmental conservation-based tourism development (agro-tourism) in Sajang Village. The periodicity of natural resource utilization aims to determine the rhythm of plant growth, which is indicated by the presence of fruit and flowers as a sign of plants in their reproductive period (Zakiah et al., 2014). The utilization periodicity is carried out by interviewing the owner of the yard to find out the harvest cycle of the yard plants. This research is a descriptive exploratory research. The observations were made deliberately on 105 yards. Based on the research, the data were analyzed qualitatively, presented in the form of diagrams and descriptions and the results obtained were fruit and vegetable plants in Sajang Village of 52% or 46 types of fruiting plants once a year, 35 types or 39% of the plants bearing fruit once every three months, 6% of crops or five types of crops bear fruit every four months and 5% or a total of four crops harvest and bear fruit every two years. Ornamental plants generally flower during the rainy season, namely in November-May as many as 97 types of plants or 71%, and as many as 29% or 40 types of plants there are ornamental plants that flower throughout the year.Keywords: periodicity, agro-tourism, home plant

Komposisi Bakteri Saluran Pencernaan Belut Rawa (Synbranchus Bengalensis)
Full text linkAbstract. Eels are a group of snake- shaped fish belonging to the Synbranchidae. Bacteria in groups of fish such as eels can be found on the body surface and digestive tract. Some bacteria are pathogenic, while a number of other bacteria are beneficial, but researches in this topic has not been optimal. This study examined the bacterial composition of the digestive tract of swamp eel (Synbranchus bengalensis) using descriptive exploratory methods. The results showed that the composition of bacteria found in the digestive tract of swamp eels was diverse but dominated by gram-positive bacteria; BR2, BR3, BR4, BR5. In addition, some of these bacteria belong to the group of proteolytic bacteria; BR2 and BR4, lipolytic bacteria; BR2, and amylolytic bacteria; BR1 which hydrolyzes digestive enzymes can act as probiotics in the digestive tract of swamp eels (Synbranchus bengalensis).Keywords: swamp eels, microflora digestive, Synbranchus bengalensi
Gambaran Kinerja Pengomposan Limbah Padat Rumah Potong Hewan Tamangapa Kota Makassar dengan Sistem Aerasi Pasif
Full text linkAbstract. Slaughterhouse waste is generally disposed into the environment without being processed, so that it potentially causes air pollution, water pollution, and soil pollution. Slaughterhouse waste can be processed and used as plant fertilizer through the composting process. This study aims to compare the composting performance of solid waste at Tamangapa RPH Makassar between the main ingredient consisting of rumen contents only (treatment I) with that consisting of a mixture of rumen contents with livestock manure (treatment II). We recorded quantitative data including temperature (0C), pH, material mass reduction and composting time and qualitative parameters including color, smell and texture of the resulting compost. The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Our results demonstrated that treatment I and treatment II had a similar pattern of temperature changes, while the average pH of treatment I was higher compared to treatment II. Based on the composting performance data including changes in temperature and pH from the first week to the fourth week of composting, we concluded that both treatments resulted in a rapid composting process with good-quality compost.Keywords: composting performance, RPH solid waste, composting process, rumen contents, passive aeration
