Abstract

Stripper is a separation process between a mixture of two liquid phase substances by using a gas phase substance as a separator. In this case, glycerol and H2O are used as a mixture and steam is used as a separating agent with the aim of removing the H2O content contained in the glycerol. In the separation process, variable variations are used in the form of concentrations of glycerol and H2O, respectively, concentrations of 70 %, 80 %, and 90 % against a predetermined temperature and pressure of 140oC and 45 Psi, with the aim of knowing what the glycerol and H2O concentrations are in the separation process. can work optimally. The process that occurs is a separation process based on boiling point, where water which has a lower boiling point of 100oC will be separated from glycerol with the help of steam with a temperature of 140oC. At a variable concentration of 70 % glycerol feed with a predetermined temperature and pressure, the data obtained is that the product still contains 4 % water in the glycerol product, the results of the process still do not meet the desired product conditions, namely 99.5 %. On the other hand, with a variable concentration of 90 % glycerol, this product only contains 1 % H2O, it can be concluded that the concentration of feed glycerol on H2O is very influential in the process of eliminating H2O levels in glycerol, because the higher the concentration of glycerol on H2O the work of steam in binding H2O is lighter so that steam can strip the H2O content in the feed more maximally.

Abstract

El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD)` are events where the phenomenon of rising and falling sea surface temperatures becomes unnatural. Stronger events where the sea surface temperature anomaly becomes large, then this disrupts local fish and bird populations. The ENSO and IOD phenomena also affect rainfall in several parts of Indonesia. This study analyzed the effect of ENSO and IOD phenomena on rainfall in South Sumatra Province from 1981 to 2020 and the correlation between Consecutive Dry Days (CDD) and Rainfall in South Sumatra Province for the last 40 years. ENSO data and IOD data were analyzed against rainfall data analyzed using a simple linear regression method and associated with CDD in South Sumatra Province with the correlation method. In addition, a correlation analysis was also carried out between the Niño 3.4 index and the Dipole Mode Index (DMI) with rainfall at two stations, namely the Palembang Climatology Station and the Sultan Mahmud Badaruddin II Meteorological Station to determine how much influence the ENSO and IOD phenomena had on rainfall in the Sumatra Province. South. The results of the analysis show that the effect of ENSO and IOD on rainfall at each station is generally not significant. The state of rainfall in the Province of South Sumatra for the last 40 years is almost not influenced by El Nio and La Nia. This is presumably due to the location of the South Sumatra Region which is in the Munsonal area. Monsoon areas are characterized by a unimodial type of rainfall (one peak of the rainy season) where in June, July and August the dry season occurs, while December, January and February are the wet months. The remaining six months is a transitional or transitional period (three months of transition from dry season to rainy season and three months of transition from rainy season to dry season).

Abstract

Control of dengue hemorrhagic fever (DHF) mosquitoes is generally carried out using synthetic pesticides. The use of synthetic pesticides is considered effective, practical, efficacious and economically more profitable. However, the use of synthetic pesticides continuously and repeatedly can cause environmental pollution, death of various types of living things and resistance from eradicated pests. One alternative that can be used to overcome the above problems is the use of natural insecticides (c), namely the Angsana plant (Pterocarpus indicus). This study aims to determine the effect of the compounds contained in the extract of the leaves of Angsana (Pterocarpus indicus), so the GCMS (Gas Chromatography Mass Spectrometry) test was carried out. The samples in this study were Aedes aegypti mosquito larvae in which each treatment group consisted of 25 larvae. Based on the results of the study it was found that there was an effect of the bioactive compound content of Angsana leaf extract (Pterocarpus indicus) as a vegetable insecticide on the larvae of the Aedes aegypti (L.) mosquito vector of dengue in the Banjarmasin region using ethyl acetate as a solvent at a concentration of 0.25%, 0.5 %, and 1%. While the most efficient concentration is 0.5% because it can kill Aedes aegyti larvae. Then based on the GCMS analysis results of the ethyl extract of Angsana leaves (Pterocarpus indicus) showed several compounds that have the potential as bioactive larvicidal compounds, namely Palmic Acid, Palmitate, Araldite 502, and Lupenone

Abstract

Nampol Formation of the Southern Mountains of eastern Java (Indonesia) has a distribution from its type location in Pacitan to the South Malang area. In the research area, this formation consists of clastic limestone with black shale inserts, claystone, siltstone, carbonate sandstone and claystone which are interpreted to be deposited in a restricted platform interior environment with closed water circulation. A total of three samples were analyzed to evaluate the organic matter content, kerogen type, thermal maturity, and hydrocarbon generating potential. Samples were taken from clastic carbonate deposits of the Nampol Formation. Based on the results of geochemical analysis, the three samples from the Nampol Formation have a TOC content of 3.48 - 26.18 wt% and possess good to excellent hydrocarbon generating potential. Hydrogen Index (HI) values for the studied samples ranged from 43 to 86 mg HC/g TOC and S1+S2 results ranged from 1.52 to 19.55 mg HC/g rock, indicating that the sample has the potential to produce gas. All three samples were dominated by Type III kerogen and were thus considered gas prone based on the HI vs. Tmax diagrams. The three samples were categorized as thermally immature based on Tmax pyrolysis analysis and Vitrinite Refl ectance (VR) values in the range of 0.44 to 0.46 % Ro. Based on the results obtained, the black shale and coal in the Nampol Formation has the capability to generate hydrocarbon but are considered as an immature source rock that can be predicted to produce gas at its peak maturity.

Abstract

The phenomenon of the use of the Jolly Roger symbol, a pirate flag, in the anime One Piece by Indonesians during Independence Day in August 2025 gave rise to an interesting symbolic battle between representations of the people and the state. In this context, this article explores how popular cultural symbols can be used as a tool of visual resistance against state nationalism that is considered to be losing legitimacy, especially in the increasingly connected digital era. The Jolly Roger symbol, known as the pirate flag, is not only seen as a symbol of freedom in pop culture, but also as an expression of rejection of nationalist narratives that are considered "fake" or not representing the interests of the people. Using Roland Barthes's semiotic approach (denotation, connotation, myth) and Gramsci's and Stuart Hall's theories of cultural hegemony, this article analyzes the layered meanings of the Jolly Roger symbol in the Indonesian socio-political context. In this semiotic analysis, the symbol is understood not only as an image representing freedom or rebellion, but also as a tool to express dissatisfaction with narratives of independence and citizenship dominated by the state. Data obtained from social media posts (X/Twitter, TikTok, Instagram), memes, captions, and official statements were semiotically analyzed to see how this symbol is used to challenge the state's sole claim to the meaning of nationalism. The results show that this pirate symbol functions beyond aesthetic resistance; it also functions ideologically by creating space for alternative articulations of identity and nationhood. In a digital context, this symbol voices criticism of official narratives of independence and citizenship, opens up a crisis in existing hegemonic narratives, and creates a space for people to freely express their views and identities.
