Abstract

Lime or Citrus aurintifolia (CA) is a type of medicinal plant that has long been used by local communities in Indonesia. Besides being used as traditional medicine, the fruit is also used for a variety of food or drinks. The use of plants as traditional medicine is related to the bioactivity and content of secondary metabolites. This study aims to explain the relationship between the use of CA as traditional medicine and its bioactivity. The method used is a literature review published online on Google Scholar and also scientific journals about CA using CA keywords, CA uses, and CA biaoctivities, then synthesized so as to obtain comprehensive information. In ethnobotany CA is used to treat fever, sauna ingredients, cough medicines, to increase stamina, overcome hypertension, and anti-cholesterol. Various researchers have successfully demonstrated the bioactivity of CAs which are anticholesterol, antimicrobial, antioxidant, antihypertension, antiosteoporosis and anticancer. Essential oils found in the leaves and fruit are compounds responsible for their bioactivity. The ability of CA as an antimicrobial can be very potential to be developed for health as well as a natural food preservative.

Abstract

The purpose of this study was to determine the diversity index of plankton in the Komering River Serdang Menang Village, Sirah Pulau Padang District, Ogan Komering Ilir Regency.  This research was conducted in March until April 2018 in the Komering River in Serdang Menang Village, Sirah Pulau Padang District, Ogan Komering Ilir Regency. Sampling method uses Purposive Random Sampling which consists of 3 observation stations, namely: station 1 sand mining area, station 2 floating net cage fish farming area and station 3 densely populated area. The results of the study found that the composition of plankton in the Komering River in Serdang Menang Village, Subdistrict of Sirah Pulau Padang in Ogan Komering Ilir Regency consisted of 3 phytoplankton classes, namely Bacillariophyceae, Chlorophyceae and Cyanophyceae, while the zooplankton class consisted of 4 classes, namely Mastigophora, Monogononta, Crustacea and Ciliophora. The highest diversity index for phytoplankton was obtained at stasion 1 in the sand mining area with a value of 1,39, which indicates that the level of diversity is included in the mediun category. At zooplankton the highest diversity indev was found at station 3 with a value of 0,33 which indicates that the level of diversity is included in the low category. While the highest dominace index in phytoplankton was found in station 3 in densely populated areas with a value of 0,43 while in zooplankton it was found in stasion 1 in the sand mining area with a value of 0,00563, both value indicate that there is no genus of plankton that dominates in the area.

Abstract

The Palembang city still has several locations for Final Disposal Sites, one of which is located in Sukarame District. Sukawinatan landfill began operations in 1994 with a land area of 25 hectares and has been used 15 hectares, the remaining 10 hectares of land is estimated to be able to accommodate waste until 2028. In some part, groundwater is still used for daily life originating from groundwater, especially in RT 68, which is used for domestic needs such as bathing, brushing teeth, washing clothes, washing utensils, and cooking. The results showed that based on the physical parameters it was concluded that 5 odor samples fulfilled the requirements, 5 taste samples fulfilled the requirements, 4 samples of dissolved solids met the requirements, 3 turbidity samples fulfilled the requirements, and 5 temperature and color samples met the requirements. Based on the chemical parameters it was concluded that the five samples did not exceed the maximum permissible levels except for pH parameters. Based on organic chemical parameters it is concluded that all samples meet the criteria of organic chemistry. The water quality index of all good samples is very good.

Abstract

This article discusses the application of graph colouring to the placement of students room. The sample data used is the data of prospective students resident ofInstitut Teknologi Sumatera. The graph colouring process in this article utilizes the Welsh-Powell algorithm and related algebraic theories to facilitate the data processing. The process is carried out to find out the minimum number of rooms needed to place a number of students so that there are no students come from the same study program or UKT group in one room. ABSTRAK Artikel ini membahas aplikasi pewarnaan graf pada penempatan kamar mahasiswa. Sampel data yang digunakan adalah data calon mahasiswa penghuni asrama Institut Teknologi Sumatera. Proses pewarnaan graf pada artikel ini memanfaatkan algoritma Welsh-Powell dan teori aljabar terkait untuk mempermudah proses pengolahan data. Proses tersebut dilakukan untuk mengetahui jumlah minimum kamar yang dibutuhkan untuk menempatkan sejumlah mahasiswa sehingga tidak ada mahasiswa yang berasal dari program studi atau pun golongan UKT yang sama dalam satu kamar.

Abstract

ABSTRACT Cane is one of the plantation commodities managed as raw material for making sugar. PT. Cinta Manis as one of the sugar producers has sugarcane production and management activities on a large scale. Production of sugar with raw material in large quantities every day, produces a by-product of sugarcane bagasse waste. Currently sugarcane bagasse waste is only used as compost after going through several stages of processing. The study was conducted in a laboratory by physically changing cane bagasse to ash through burning. Furthermore, the ash from the sugarcane bagasse was added to high quality concrete K-300. The results of the laboratory tests carried out showed that the addition of Cane Bagasse Ash (CBA) by 5% can increase the compressive strength of the concrete 6.43% higher than the normal compressive strength of the concrete. However, the addition of CBA which is greater than 5% to the cement in the concrete actually decreases the quality of the compressive strength of the concrete. This means that the 5% CBA content can be used to increase the compressive strength of concrete.

Abstract

Cork Fish (Channa striata) and Baung Fish (Mystus)is a fish that has a high nutritional value and many produced from the Musi City Palembang River. Activities in the region can produce waste that can harm water environment such as industrial waste and domestic household waste. This research aims to determine the level of heavy metals lead (Pb) in Cork fish (Channa striata) and Baung Fish (Mystus) originating from the Musi city of the river Palembang. Random sampling method on fish suppliers in the traditional market of Palembang by using the method of atomic absorption spetrophotometry. Based on the results of measurements made, heavy metal content of Pb Cork fish meat average of 0.1036 mg/kg and on average Baung fish meat 0.1425.As for the gills of the cork, the rate of Thymbalnya ranges between 0,0911-0,0953 mg/kg and in the gills of the fish range between 0,1117-0,1843 mg/kg. There are heavy metal contaminants in the meat as well as the fish Cork (Channa striata) and Ikan Baung (Mystus) derived from the waters of the Musi River that is the city of Palembang where the heavy metal levels lead to the fish is higher compared with fish meat.

Abstract

An individual of the Catius Rona Hedge Blue Udara rona catius (Fruhstorfer, 1910) was found and photographed on 28 April 2018 in Jambul Highlands, South Sumatra province, Indonesia. After photographed, the butterfly was identified using major references. This incidental finding of Udara rona catius is a first record for southern Sumatra. The potential host plants of U. rona catius in Jambul Highlands are plants from family Euphorbiaceae (Aporosa sp., Cleoxylon sp., Croton sp., Endospermum sp., Macaranga sp. and Phyllanthus sp.) and Fagaceae (Castanopsis sp., Lithocarpus sp. and Quercus subsericea).
