Pineapple juice is frequently consumed for its extensive health benefits, but is prone to microbiological degradation. Pasteurization – as a current preservation technique – have been degrading the nutritional qualities of fruit juices, and the use of synthetic preservatives have been perceived negatively by consumers. In this study, lemongrass essential oil was applied for the preservation of pineapple juice. Agar Well Diffusion Method was used for antimicrobial activity screening of lemongrass essential oil against E. coli, S. cerevisiae, and A. niger, while Broth Macrodilution Method was used in determining Minimum Inhibitory Concentration (MIC) of lemongrass essential oil, which was evaluated to be 0.1%. Furthermore, the addition of 0.1% lemongrass essential oil into pineapple juice had a negative impact regarding the sensorial acceptability, but was able to significantly suppress the microbial count for bacteria, yeast, and mould during 5 days of storage time in chilling temperature (4oC). Vitamin C content degradation and pH changes during storage were not significantly affected by the addition oflemongrass essential oil. Furthermore, the addition of 0.1% lemongrass essential oil was observed to be not synergistic with the enzyme activity of pineapple juice, and has negatively impacted the enzyme stability of the pineapple juice.

Diabetes is a chronic disease characterized by elevated blood glucose level.Reducing carbohydrate absorption from the intestinal tract is an effective strategy to control post-meal blood glucose level. Inhibition of intestinal α-glucosidase, involved in digestion of carbohydrates, is known as an approach to accomplish this. On the other hand, reduction of α-glucosidase amount is expected to work in the similar manner. However, none of the previousstudy pursues this approach. A convenient assay was developed to evaluate α-glucosidase amount employing Caco-2 cells, the intestinal epithelial cell model reported to express α-glucosidase. Sixty plants were screened and two candidate plants, Calluna vulgaris and Perilla frutescens var. crispa were found to reduce α-glucosidase expression. C. vulgaris extract was subjected to activity guided isolation. Proanthocyanidin was identified as the active principle which was analyzed by thiol decomposition to reveal the components as a mixture ofcatechin, epicatechin, epigallocatechin, and A type procyanidin dimer. The proanthocyanidin suppressed about 30% of α-glucosidase amount evaluated through convenient assay, and suppressed bulk of mRNA expression level of sucrase-isomaltase (SI) at 0.125 mg/mL. Several flavan-3-ol monomers were also tested, and epicatechin gallate and epigallocatechin gallate were found to suppress α-glucosidase amount significantly.
糖尿病是一种以血糖升高为特征的慢性疾病。减少肠道碳水化合物的吸收是控制餐后血糖水平的有效策略。抑制参与碳水化合物消化的肠道α-葡萄糖苷酶被认为是实现这一目标的一种方法。另一方面，α-葡萄糖苷酶量的减少预计也以类似的方式起作用。然而，之前的研究都没有采用这种方法。建立了以Caco-2细胞(已报道表达α-葡萄糖苷酶的肠上皮细胞模型)评价α-葡萄糖苷酶含量的简便方法。对60株植物进行筛选，发现愈伤组织和紫苏(Perilla frutescens var. crispa)两种候选植物可降低α-葡萄糖苷酶的表达。采用活性引导分离方法分离荆芥提取物。经硫醇分解分析，其活性成分为儿茶素、表儿茶素、没食子儿茶素和a型原花青素二聚体的混合物。原花青素对α-葡萄糖苷酶的抑制作用约为30%，在0.125 mg/mL时抑制了蔗糖-异麦芽糖酶(SI) mRNA的表达量。几种黄烷-3-醇单体也进行了测试，发现表儿茶素没食子酸酯和表没食子儿茶素没食子酸酯能显著抑制α-葡萄糖苷酶的数量。

The continuous blood pressure measurement research is widely known for helpingthe development of ambulatory blood pressure monitoring where it measures blood pressureevery 15 to 30 minutes throughout the day. The cuff is a problem for the patient withAmbulatory Blood Pressure Monitor. It can make a person feel uncomfortable and must staystill when the cuff starts to inflate. It is limiting and disturbing their daily activity when thedevice is starting to measure the blood pressure. Blood pressure measurement without cuff isbeing proposed in this research, called cuff-less blood pressure measurement. It will be based onPhotoplethysmography (PPG) and Electrocardiography (ECG) signal analysis. ECG (Lead 1,Lead 2, and Lead 3) with PPG signal produced from index finger on the left hand are comparedand analyzed. Then the relation of PPG and ECG signal and the optimum location for daily usecan be obtained. The optimum location will be based on the electrode’s position that producedthe optimum ECG lead Signal to measure blood pressure. Based on the result, PPG and ECGsignal have a linear relation with Blood Pressure Measurement and Lead 1 is more stable inproducing the ECG signal. The equation from Lead 1 appeared as one of the optimum equationsfor measuring Systolic Blood Pressure (SBP) or Diastolic Blood Pressure (DBP).

This study conducted to find the appropriate way to serve butterfly pea flower drink at home. The colorless, red, purple, and green transparent glass and colorless glass covered by aluminum foil used to contain four grams butterfly pea petal. A 250 ml of boiling water poured to the glass to soak the petal for 60 minutes. The color intensity and total anthocyanin of the liquid measured every five minutes. The regression slope analysis exhibited that light gave no significant decrease in color intensity and total anthocyanin. About 83% of color and anthocyanin extracted within 5 minutes. There was no significant increase of the color and anthocyanin after 30 minutes. Therefore, the maceration of butterfly pea flower in boiling water for five minutes was appropriate to serve the drink. Furthermore, to reach the maximum color and anthocyanin content the 30 minutes maceration is needed. The maximum anthocyanin content of the drink was 19.57 ± 1.16 mg/l or equal to 1.22 ± 0.07 mg per gram fresh petal.

The Internet has become the biggest medium for people to communicate with otherpeople all around the world. However, the Internet is also home to hackers with maliciouspurposes. This poses a problem for Internet Service Providers (ISP) and its user, since it ispossible that their network is compromised and damages may be done. There are many types ofmalware that currently exist on the Internet. One of the growing type of malware is botnet.Botnet can infect a system and make it a zombie machine capable of doing distributed attacksunder the command of the botmaster. In order to make detection of botnet more difficult,botmasters often deploy fast flux. Fast flux will shuffle IP address of the domain of themalicious server, making tracking and detection much more difficult. However, there are stillnumerous ways to detect fast flux, one of them is by analysing DNS data. Domain Name System(DNS) is a crucial part of the Internet. DNS works by translating IP address to its associateddomain name. DNS are often being exploited by hackers to do its malicious activities. One ofthem is to deploy fast flux.Because the characteristics of fast flux is significantly different thannormal Internet traffic characteristics, it is possible to detect fast flux from normal Internettraffic from its DNS information. However, while detecting fast flux services, one must becautious since there are a few Internet services which have almost similar characteristics as fastflux service. This research manages to detect the existence of fast flux services in an ISPnetwork. The result is that fast flux mostly still has the same characteristics as found on previousresearches. However, current fast flux trend is to use cloud hosting services. The reason behindthis is that cloud hosting services tend to have better performance than typical zombie machine.Aside from this, it seems like there has been no specific measures taken by the hosting service toprevent this, making cloud hosting service the perfect medum for hosting botnet and fast fluxservices.

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.

From many years, researchers try to solve problems involves examining the solution of human aging phase. Growth Hormone (GH) is a hormone inside our body that known can regenerate and stimulates cell growth. Growth hormone levels decline as we grow older as a result, gene stops working and our bodies are less capable of repairing damage cells. Nowadays, it is believed that Growth Hormone releaser can be obtain from external sources, a natural source. Colostrum milk is a first milk that produced by mammals during pregnancy. It is a thick yellow liquid and rich in carbohydrates, protein, and antibodies to help keep the newborn healthy. It is also full of antibodies and immunoglobulins that can help protect newborns as they come into our world of bacteria and viruses. With the help of Edamame, that is one of the biggest vitamin B sources and amino acids, both of this external sources of ingredients will help to increase Growth Hormone (GH) inside human body. This research was done by give asubject (human) treatment and observe their physical reaction and Growth Hormone level. From the test conducted, subjects body shows a positive reaction such as healthier according to the health observation. For the HGH level, subjects showed an increase of HGH in the test result that conducted in laboratories. Hence, the treatment of using colostrum milk and edamame with additional ingredients (royal jelly, carrot, zinc tablet) still needs to be develop and deeply study in the future.

Growth Hormone (GH) is a hormone inside our body that known can regenerate and stimulates cell growth. Growth hormone levels decline as we grow older as a result, gene stops working and our bodies are less capable of repairing damage cells. Nowadays, it is believed that Growth Hormone releaser can be obtain from external sources, a natural source. Colostrum milk is a first milk that produced by mammals during pregnancy. It is a thick yellow liquid and rich in carbohydrates, protein, and antibodies to help keep the newborn healthy. It is also full of antibodies and immunoglobulins that can help protect newborns as they come into our world of bacteria and viruses. With the help of Edamame, that is one of the biggest vitamin B sources and amino acids, both of this external sources of ingredients will help to increase Growth Hormone (GH) inside human body. This research was done by give asubject (human) treatment and observe their physical reaction and Growth Hormone level. From the test conducted, subjects body shows a positive reaction such as healthier according to the health observation. For the HGH level, subjects showed an increase of HGH in the test result that conducted in laboratories. Hence, the treatment of using colostrum milk and edamame with additional ingredients (royal jelly, carrot, zinc tablet) still needs to be develop and deeply study in the future.","PeriodicalId":13150,"journal":{"name":"ICONIET PROCEEDING","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75258561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An energy supply system consists of a system of power plants and transmission anddistribution systems that supply electrical energy. The present project is limited to the modellingof the generation system. Its objective is the design and implementation of a web-basedapplication for simulating energy supply systems using the Laravel framework. The projectfocuses on six modules representing geothermal energy, solar energy, biopower, hydropower,storage, and fossil-based energy that are allocated to satisfy a given power demand. It isexecuted as a time series modelling for an exemplary year with hourly resolution. Thedevelopment of the software is divided into four steps, which are the definition of the userrequirements, the system design (activity, use case, system architecture, and ERD), the softwaredevelopment, and the software testing (unit testing, functionality testing, validity testing, anduser acceptance testing). The software is successfully implemented. All the features of thesoftware work as intended. Also, the software goes through validity testing using three differentinput data, to make sure the software is accurate. The result of the testing is 100% accuracy withrespect to the underlying model that was implemented in an excel calculation.
