Abstract

The performance of ethanol distillation is determined by the type of reboiler used in the distillation column. This study aims to determine the effect of differences in diameter and height of internal reboiler tubes, as well as feed content on ethanol distillate concentration and distillation yield. The research was conducted on a batch ethanol distillation process using a rectified distillation device with an internal vertical tubular baffle reboiler using different diameters and tube height, namely 1.5, 1, and 0.5 inches of diameter, and 8, 6, and 4 cm of tube heights. Materials or feeds in this study were ethanol solutions with levels of 10%, 20%, and 30% v/v. The results showed that the highest ethanol distillate content of 97.17% v/v (average) was achieved in the distillation process using an internal reboiler with a diameter of 0.5”, a tube height of 8 cm, and a feed content of 10%. Geometry affected the heat transfer process in the internal reboiler of a distillation device so that it affected the distillation results.Keywords: distillation; ethanol; internal reboiler: performanceA B S T R A KKinerja alat distilasi etanol ditentukan oleh jenis reboiler yang digunakan pada kolom distilasi.

Abstract

Abstrak. Generator HHO merupakan alat yang menggunakan prinsip elektrolisis air untuk memisahkan unsur-unsur kandungan air murni (H2O) menjadi Gas HHO, dalam upaya peningkatan performanya tentu dibutuhkan bahan konduktor yang memiliki sifat kelistrikan baik. Penambahan plat elektroda netral ialah bertujuan untuk meningkatkan performa elektroliser dan mengatasi berbagai macam permasalahan yang terjadi pada saat proses elektrolisis air bekerja. Penelitian ini menunjukkan bahwa plat elektroda netral aluminium mampu meningkatkan nilai performanya sedangkan untuk plat SS 316 mampu meminamalisir persentase losses energy. Larutan AMDK murni terbukti mampu meningkatkan produktivitas gas dibandingkan dengan larutan aquades murni, tetapi kelemahan dari larutan AMDK yaitu mudahnya terbentuk gel-gel, sehingga menghambat pergerakan elektron dan laju aliran produksi. Karateristik sifat bahan sangat berpengaruh terhadap pencapaian kinerja Generator HHO karena tidak semua jenis plat elektroda netral mampu meningkatkan performanya. Sifat-sifat kelistrikkan bahan yang sangat berpengaruh ialah sifat keelektronegatifan atau potesial elektroda dan koefisien nilai muai dari suatu bahan konduktor. Usage Study Neutral Electrode Plate Stainless Steel 316 and Aluminium of Performance Generator HHO Dry Cell TypeAbstract. Generator is a tool that use principle of water electrolysis to separated the element of pure water conscience (H2O) be HHO gas, in effort to increase the perform of HHO Generator is needed a conductor ingredients which has a good electricity character the direction of addition neutral electrode plate is to increase the electrolyzer perform and to overcome every problem that happen when the water electrolisys process is going. This research shows that neutral electrode aluminium plate can increase the performance value and the SS 316 plate can minimize the percentage of losses energy. The pure AMDK solution proofs that can increase the gas productivity than the pure aquadest solution, but the weakness of AMDK solution can to form gel easily, which cause the electrons movement and the flowrate production are blocked. The characteristic of water usage is influence to HHO Generator work maximum value, because for every type of netral electrode plate can’t increase the performance of generator. The electricity characteristic of material that every influence is the electronegatifity character or electrode potential and the expansion coefficient from the conductor materials.

Abstract

Suco Village has great potential in the fields of agriculture and animal husbandry. People in Suco village generally raise goats or sheep, and some raise cattle. Livestock in Suco village already uses an integrated livestock concept. Some livestock waste in Suco village is utilized, some is not managed properly. A goat and sheep farm with a capacity of 50 heads will produce around 25 kg of solid manure per day. This will cause environmental and health problems if not managed properly. The training on making organic fertilizer from livestock manure was carried out as part of the 2024 Innovation activities. The training activity aimed to increase knowledge and inspire participants in making organic fertilizer. The activity was attended by all members of the Productive Farm and King Farm livestock groups. During the training, participants increased their knowledge about variations in the composition of organic fertilizers which influence the effectiveness of fertilizers and also how to become a fertilizer entrepreneur, as well as how to market them. The training activities ran smoothly and successfully accompanied by the enthusiasm of the participants. With this activity, it is hoped that it can increase the productivity of organic fertilizer in Suco village, thereby improving its economy.

Abstract

The reduction of FFA levels in used cooking oil as a biodiesel raw material is generally done by the esterification process. Another method that can be used to reduce FFA levels is through the adsorption method. The adsorbent used is bottom ash waste. This study aims to determine the effect of bottom ash adsorbent variation and determine the best variation based on Taguchi analysis. This research uses Taguchi data processing technique with 2 factors and 3 levels. The first factor is adsorbent mass with variations (5% m/v, 10% m/v, and 15% m/v). The second factor is the length of adsorption time with variations (30 minutes, 60 minutes, and 90 minutes). The testing parameters included FFA content, acid number, density, and viscosity. The results of this study were analyzed using the Taguchi method which shows the variation of adsorbent mass and time for FFA content is the variation of 5% m/v adsorbent mass and 30 minutes adsorption time which can reduce FFA by 35.2%, with an acid number value of 3.029 mg KOH/g, density of 0.903 g/cm3 and viscosity of 4.463 sCt in samples that successfully reduced the FFA value by 35.2%.

Abstract

Closed-house broiler chicken farming enhances productivity and animal welfare by maintaining optimal environmental conditions. However, reliance on grid electricity for air control systems increases operational costs and environmental impact. This study investigates the implementation of a solar-powered air control system to regulate temperature, humidity, and ventilation in closed-house broiler farming. The system integrates photovoltaic (PV) solar panels, energy storage, and a smart control mechanism. The system's performance is evaluated based on energy consumption, solar energy generation, and environmental parameters. Results show the system effectively maintains optimal broiler growth conditions while reducing energy dependence. Energy savings of up to 10% are achieved, leading to lower operational costs and improved sustainability.The findings demonstrate the feasibility of solar-powered solutions in broiler farming, reducing greenhouse gas emissions and enhancing farm resilience. Future work will explore IoT integration for real-time monitoring and further energy optimization.

Abstract

The increasing demand for renewable energy has driven the development of bioethanol as an alternative fuel to replace or blend with fossil fuels, offering high prospects in the future. Driven by these high prospects, bioethanol production has begun to be widely carried out. However, the bioethanol production process tends to be complex, including fermentation and distillation processes that require intense and strict monitoring. Monitoring of both processes consists of essential parameters that must be considered, such as temperature, pH, and ethanol content, as time series data is taken intermittently and continuously. This monitoring or supervision determines the quality and success of the bioethanol production process from biomass materials, in this case, using fermented and distilled sugarcane juice. This study aims to design and implement a bioethanol production process monitoring system based on the ESP8266 microcontroller and ESP32 SoC. Both micro modules are implemented in a hybrid with HTTP communication for data logger output on a cloud service. This system uses a DS18B20 temperature sensor, a pH sensor, and an MQ3 ethanol gas sensor programmed using the Arduino IDE. The development method used is the waterfall method. Several stages include needs, including system design, implementation, hardware and software testing, and system maintenance. The implementation results show success and satisfactory achievements from the performance analysis of the sensors used. The system can monitor parameters with low errors, <1% at temperature, <10% at pH, and can detect alcohol content up to 96% of the bioethanol produced.
