Public cemeteries are considered to be a potential source of groundwater pathogen contamination. Many settlements in Indonesia are located near cemeteries and rely on groundwater for consumption. However, there is no information available on whether the simple method of boiling can improve the microbiological quality of groundwater around cemeteries. Therefore, this experimental study aimed to determine the effectiveness of boiling in improving the microbiological quality of groundwater around Bonoloyo Cemetery. The study had two treatments: groundwater without boiling (control) and groundwater that had been boiled. Samples were collected from two points (S1 and S2) inside the cemetery and three points (S3, S4, and S5) outside the cemetery. The microbiological quality of groundwater was analyzed using the MPN method for each treatment. Samples that produced gas in positive tubes were inoculated on eosin methylene blue (EMB) media. The results of the study showed that S1, S2, S3, and S5 had total coliform levels that exceeded the normal threshold for water. Fecal coliform was found in S3 and S5. However, after boiling, there was an average decrease in total coliforms in samples S1, S3, S4, and S5. There was also no growth of E. coli in samples S3 and S5. The decrease in MPN values in the samples indicates that boiling can improve the microbiological quality of groundwater at cemetery Bonoloyo Surakarta.

The Bun-bun River was located in a mangrove forest area in Kubu Raya Regency and empties into the sea. As the main producers at the trophic level of waters, phytoplankton has an important role in assessing river quality. This study aims to find out phytoplankton community structure including abundance, diversity, uniformity, and dominance indexs in relation to Bun-bun River quality. The observations were made in the dry and rainy seasons at three stations starting from the initial end of the mangrove forest (Station 1), the middle (Station 2), and the final end which also empties into the sea (Station 3). Sampling was carried out at three points (left edge, center, right edge). Measurements of physico-chemical factors include brightness, current velocity, temperature, pH, DO, dissolved CO2, salinity, nitrate and phosphate. Phytoplankton sampling used a 30 µm plankton net mesh size and identification down to the species level. The calculated index values include abundance, diversity, uniformity, and dominance. The Bun-bun River was characterized by brackish waters with calm surface currents (<0.1 m.s-1) and a salinity between 5.4-9.48 ppt. Dissolved CO2 levels are relatively high, namely 22-30.8 mg.L-1 in the dry season and 35.2 mg.L-1 in the rainy season. During the dry season, the pH of the water becomes slightly acidic (6.51-6.76) and relatively neutral during the rainy season (7.08-7.52). Nitrate and phosphate levels were low in both seasons and all three stations. The brightness of the water was higher in the dry season than in the rainy season (20-44 cm). A total of 52 types of phytoplankton were found belonging to four classes, namely Class Bacillariophyceae (25 species), Dinophyceae (14), Chlorophyceae (12), and Chrysophyceae (1). Phytoplankton abundance index was low to moderate. The diversity index was moderate at almost all stations except for the low at Station 3 in the rainy season. The uniformity index at Station 3 was low in the dry season but high in the rainy season, and moderate in other locations. The dominance index was high at Station 3 during the dry season and moderate at other locations. Physico-chemical factors such as salinity, dissolved CO2, nitrate and phosphate levels are most likely to influence abundance, while diversity was influenced by dominance.

Infection is a disease that often occurs in Indonesia. This disease is caused by pathogenic microbes, one of which is bacteria. Staphylococcus aureus and Escherichia coli are bacteria that cause infection. Pharmacological therapy for bacterial infections used to use antibiotics, currently tends to use drugs that come from nature. One of the plants that has the potential as an antibacterial is gadung mango leaves. This study aims to determine the effectiveness of mango leaf ethanol extract against S.aureus and E.coli bacteria. The method used was well diffusion with concentrations of ethanol extract of mango leaves 0.5% (S1), 0.75% (S2), 1% (S3), streptomycin (K+), and ethanol (K-), respectively treatment was repeated 5 times. Data that can be analyzed using One Way ANOVA with a significant level of 0.05. Based on the results of the antibacterial extract of ethanol extract of mango gadung leaves, it has the potential to be better on E. coli bacteria, namely at a concentration of 1% (S3) of 16.05 mm, whereas on S.aureus K+ bacteria (Streptomycin) it is better on control + of 15.9 mm.

Zingiberaceae is a family of aromatic herbaceous plants, pseudostem, and rhizomes. Members of this species are found in the low-high lands (2000 meters above sea level), in areas with very high rainfall, and in humid places. Resort Joben is located in the south of Mount Rinjani so the water source is quite abundant and the humid forest conditions are a place to grow various species of Zingiberaceae. This study aims to determine the species and distribution of Zingiberaceae in the Joben Resort, Rinjani Mount National Park, East Lombok. Sampling used the cruising method with five cruising lines, each line has a wide range of 20 meters. Morphological characters identify using the reference book Vascular Plant Systematics, and the kinship relationship dendrogram was created using past 4.09 software. Samples were collected and documented as herbarium, then identified their morphological characters and species. The results of the study found six species of Zingiberaceae which belong to three sub-family, namely Zingiberoideae: Curcuma zanthorrhiza and Hedychium coronarium; Alpinioideae: Amomum dealbatum, Etlingera spinulosa and Etlingera rubroloba, and Costoideae: Costus spiralis.

Sand and stone mining activities in Kuningan Regency cause damage to soil and environmental ecosystems, so reclamation and revegetation are carried out. The purpose of this study is to determine the existence of indigenous / local Arbuscular Mycorrhizal Fungi (FMA) found in the rhizozofer stands of Sengon (Paraserianthes falcataria) and Acacia (Acacia mangium) which are revegetation plants on the land of former sand and stone mines Cipancur village, Kalimanggis district, Kuningan regency. Sampling using the composite sampling method, FMA isolation technique using the wet pour method is then continued with the centrifugation technique and root colonization observation technique using the root staining technique (staining). The temperature of the ex-mining soil ranges from 28C – 29C, the soil pH is 5.5 including acidic, the soil moisture varies between wet, medium (slightly wet) and dry (dry) but during the rainy season the soil will become wet and even flooded. The results showed that there were 5 genera, it are Acaulospora, Glomus, Gigaspora, Sclerocytis and Scutellospora. The dominant genus is Glomus. The highest spore density was found in Sengon stands with 1,157 spores per 50 grams of soil. The highest percentage of AMF infection was at the root of Sengon stands at 69% from the ex-sand mining area.
