Endophytic fungi can produce secondary metabolites of endophytic fungi isolated from host plants. The purpose of this study is to identify and analyze the sequencing of endophytic fungi isolates with ITS and Beta-tubulin markers and phylogenetic trees. The endophytic fungi isolate DKJ1, DKJ3a, DKJ3c and DKJ4 were successfully isolated from the cardia plant (Bellucia pentamera Naudin) indicated by Aspergillus niger group, Aspergillus fumigatus group and Penicillium sp. The results of the sequencing analysis of isolates DKJ1, DKJ3a, DKJ3c, and DKJ4 were successfully amplified with an annealing temperature of 54ºC with a pair of ITS1-ITS4 primers with a molecular weight of 570 bp and a Beta-Tubulin primer with an annealing temperature of 56.1ºC molecular weight of 550 bp. From the results of identification and analysis of DNA sequencing of endophytic fungi DKJ1, DKJ3a, DKJ3c and DKJ4 with the primary pair of ITS and Beta-tubulin shows that the phylogenetic tree is different from the species obtained. ITS DKJ1 isolates have similarities with the species Aspergillus piperis CBS 112811, ITS DKJ3c has similarities with the species Aspergillus flavus var flavus strain ATCC 16833, ITS DKJ3a has similarities with Penicillium rolfsii strain NRRL 1078 species and ITS DKJ4 has similarities with Penicillium oxalicum NRRL 787 species. Whereas isolate from DKJ1 Beta-Tubulin has similarities with NRRL 4875 Aspergillus tubingensis species, DKJ3c has similarities with species of Aspergillus novoparasiticus strain DTO 223-C4 and DKJ4 has a similarity with Penicillium guaibinensis species. But there are similarities based on Cluster A (Aspergillus Group) and Cluster B (Penicillium Group) on phylogenetic trees.

Twelve endophytic fungi were isolated from the Acanthus ilicifolius plant. Two of them have the best antibacterial activity, namely Culvularia lunata and Diaporthe phaseolorum. Fungi can produce secondary metabolites that have the potential as antibacterial compounds. This study aims to isolate antibacterial compounds using column chromatography methods and test the antibacterial activity using diffusion methods to use paper discs. Isolation of secondary metabolites produces 27 eluates. From TLC, it is known that the endophytic fungi Culvularia lunata produce an active compound as an antibacterial that is phenol compound. Endophytic fungi Diaporthe phaseolorum produces three types of active compounds as antibacterial namely phenol, terpenoids, and alkaloids, each component of the active compound are tested for sensitivity to bacterias Escherichia coli, Staphylococcus aureus, Shigella dysenteriae, and Salmonella typhi. MIC values ??of terpenoid compounds with concentrations of 125-250 ppm are antibacterial compounds with good activity against Escherichia coli, Staphylococcus aureus, Shigella dysenteriae, and Salmonella typhi.

Operational Operational Analysis of Waste Transportation in Sukarami District to Sukawinatan Final Disposal Ani Firda Martawi; Rosmalinda Permatasari; Destu Lareza

Increased development, economic growth and population growth in Sukarami Sub-district also have an impact on changes in the lifestyle of its people, which are becoming more consumptive. This has led to an increase in waste production, which must be managed properly, especially in transportation to the landfill. The purpose of this study was to count the number of dump trucks needed to transport the garbage produced in Sukarami District to the final disposal site of the Sukawinatan landfill. The data collected in this study were survey data on the generation of waste per capita and the number of residents to calculate the waste generation in Sukarami District , as well as survey data on waste transportation, namely the capacity of the garbage truck, the time to load and reduce waste, travel time, travel distance, and route of travel. Secondary data collected is a map of Sukarami Subdistrict, transport vehicle routes, the number of garbage transport equipment in the form of dump trucks, the population, and the number of markets. Obtained results that large generationSolid waste generated in Sukarami District in 2019 is 427,873 m3 / day, and is predicted to increase to 450,367 m3 / day in 2023. The need for garbage transport vehicles is 29 units of dump trucks. The number of trips needed for dump trucks is 57 trips / day from 2019 - 2023, 61 trips / day for 2023. Keywords waste generation, transportation system , Sukarame District.

Environmental Characteristics of Slum Settlements in Batang Arau Village of Padang City Aziz, Rizki -; Noer, Melinda; Risna, Lisa

In order to comprehend the problems of slums comprehensively, knowledge of the environmental characteristics of slums is needed based on the classification of aspects of facilities, infrastructure, social, economic, and disaster (hazard). This study aims to understand the characteristics of the environment in the form of infrastructure, social, economic, and slum disasters in the Batang Arau Village, Padang City. Primary data were obtained through field observations and interviews with 80 informants, while secondary data obtained from related documents and regulations. The physical condition of the area is that the regularity of residential buildings is only 102 units of households with the level of regularity of buildings, only 0.26%. The level of residential building density of 522.36 units / Ha, with the feasibility of residential buildings, is only 0.76%. Accessibility following technical requirements is only 0.40%. The condition of the drainage network that meets the minimum quality standard is 0.19%. The number of houses served with water facilities for basic needs of 0.58% with the fulfillment of 0.47%. The percentage of family latrines according to technical requirements of 0.41%, and the amount of domestic household waste that is transported at least twice a week is 49%. Socially, the number of people by sex is almost the same, with the distribution of the productive age of the population of 69.32% of the total population, the level of education varies but in general is high school education, and the most dominant ethnic group in this area is the Minangkabau. From an economic aspect, people's income varies, with work predominantly being fishermen and trade/services. This area is located on a hillside, making it prone to landslides, and due to dense houses, this area is also prone to fires.

Metal cookware has been used many people for its better thermal conductivity. However this material also has some weaknesses for its reaction with acidic food which will contaminate the food. Metal-base material coated with enamel is one of the solutions. The hard and non-reactive surface has cause this material has been widely used for processing food. Lower thermal conductivity is one of the problems of enamel cookware. The experimental analysis has been conducted to investigate energy efficiency, emission rate and thermal conductivity. The efficiency is calculated by comparing the useful energy (work) with the input energy. The emission rate is calculated by multiply energy consumption with emission factor. Meanwhile the thermal conductivity is calculated by using simply conduction heat transfer equation. Based on the analysis, enamel cookware has much lower thermal conductivity than aluminum cookware. However this physical property does not much affects the efficiency. The most dominant factors which should considered are type of fuel and technology of stove which consume higher energy inefficiently and emits much higher hazardous gas
