This paper presents the design and implementation of an automatic Virgin Coconut Oil (VCO) making device using an Arduino Uno microcontroller. Virgin Coconut Oil has gained popularity due to its health benefits and versatile uses in various industries. The traditional process of making VCO involves manual effort and precise timing, which can be tedious and inconsistent. The proposed automated system aims to streamline the VCO production process by integrating sensors, actuators, and a microcontroller to achieve precise control and monitoring of the process variables. The Arduino Uno microcontroller serves as the central unit for data acquisition, processing, and control, facilitating automation through programmed logic. Key components of the automated VCO maker include temperature sensors for monitoring heating stages, a motor for stirring, and relays for controlling heating elements. The system utilizes feedback loops to maintain optimal conditions during each phase of VCO production, ensuring reproducibility and quality. The design also emphasizes user-friendly operation, with an interface that provides real-time feedback on process parameters and allows manual intervention if necessary. Safety features are incorporated to prevent overheating and ensure operational reliability. Overall, the developed automatic VCO maker offers a practical solution to enhance the efficiency and consistency of VCO production, catering to both small-scale producers and commercial enterprises in the food and cosmetic industries

Perilaku merokok tidak hanya ada di zona sekolah non pesantren, tetapi juga ditemukan di sekolah pesantren. Walaupun dalam pesantren terdapat aturan dilarang merokok, masih banyak santri yang merokok secara sembunyi, dimana salah satu tempat yang paling sering dijadikan tempat merokok mereka adalah di dalam kamar mandi asrama dan perilaku tersebut merupakan suatu pelanggaran. Pondok pesantren salafiyah safi’iyah sukorejo merupakan salah satu pondok pesantren yang sangat melarang para santrinya untuk merokok. Bahkan pelarangan merokok ini merupakan pelanggaran yang berat, dimana santri yang ketahuan merokok bisa langsung di keluarkan dari pondok. Salah satu solusi dari permasalahan ini yaitu  bagaimana merancang alat pendeteksi asap rokok berbasis IoT menggunakan sensor MQ-135 dan mikrokontroler ESP32-CAM, serta bagaimana sistem ini tidak hanya mendeteksi asap tetapi juga mengirimkan notifikasi lokasi dan mengambil gambar kejadian untuk dokumentasi.

In the fruit processing industry, peel is one of the main by-products. Non-edible portions of fruit are likewise seen as waste and are frequently thrown out into the environment. Nowadays, one of the main sources used by the pharmaceutical sector to isolate and extract secondary metabolites is fruit peels. Many applications known for lime peel, especially for antibacterial. This study focuses on the isolation, chemical composition characterization, and antibacterial activity on skin pathogenic bacteria of lime peel essential oil (LPEO). LPEO were isolated using steam distillation and characterized by GC/MS. A total of 24 components were identified. The major constituents of the LPEO were d-limonene (40.24%), ?-terpinene (15.68%), sabinene (13.15%), citral (3.41%), ?-Terpineol (3.40%), and terpinene-4-ol (2.94%). The antibacterial activity was determined using the Kirby-Baurer method against several bacteria that can cause skin infections. The antibacterial activity of LPEO against Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis dan Propionicbacterium acne is confirmed. LPEO showed varied levels of antibacteria activity against the gram positive and gram negative bacteria. Zone of inhibition (ZOI) in millimetres was used to measure the antibacterial activity, and amoxicillin was used as a control.
 

In the current covid-19 endemic, degenerative diseases still have a high prevalence and morbidity rate, one of which is hypertension. The high prevalence of hypertension can be caused by many factors such as improper lifestyle management that can be prevented by adopting a healthy lifestyle. Adults and elderly with hypertension are encouraged to receive non-pharmacological treatments to minimize risk factors for cardiovascular and other systemic and degenerative diseases. Families have an important role in providing information about hypertension and the risk of complications for patients. Families also have a role in providing appropriate care, especially during the period towards endemic covid-19. Counseling was conducted on patients and their families in Sumberejo Village, Poncokusumo District, Malang Regency. The activity was carried out with an initial examination and counseling consisting of 2 main topics: 1) what is hypertension and 2) hypertension care management by family at home. The results showed an increase in knowledge related to physical activity, high blood control, and the role of the family at home with a score of 70 and joint exercises were routinely carried out every 2 weeks. For the sustainability of the program, coordination was carried out with relevant stakeholders.

The purpose of this study is to determine the condition of intellectual capital, financial performance and firm value, to analyze and prove financial performance can be influenced by intellectual capital, to analyze and prove firm value can be influenced by intellectual capital, to analyze and prove firm value can be influenced by performance. finance, analyze and prove the value of the company can be influenced by intellectual capital through the financial performance of a chemical company. associative research is research that is causal (explains the relationship between two or more variables) and a causal relationship, there are independent and dependent variables. The population of chemical sector companies listed on the Indonesia Stock Exchange in 2017-2021, totaling 14 companies. The data used is secondary data sourced from financial statement data of chemical sector companies listed on the Indonesia Stock Exchange in 2017-2021. The data analysis technique used in this study uses path analysis which is then processed using Partial Least Square (PLS). Firm value is an investor's perception of the company's level of success which is often associated with stock prices and profitability. High stock prices make the value of the company also high. A high company value will make the market believe not only in the company's current performance, but also in the company's prospects in the future

The purpose of this study is to determine the characteristics of the cooling system on the new design of the Kartini Reactor plate fuel based on numerical calculations (Computational Fluid Dynamics). The fuel plate model was simplified and made in 3D. The model dimensions are 17.3 mm x 68 mm x 900 mm. The space between the two plates called the narrow rectangular channels has a gap of 2 mm. On these simulations a heat flux of 10612,7 watt/m2 was used which was obtained from the MCNP calculation program. Simulations were conducted in a steady state condition and single-phase model laminar flow of an incompressible fluid through the gap between the two fuel plates. This simulation uses UDF (User Define Function) to approach heat flux behaviour that follows the neutron distribution in the reactor core. The simulation results show that the maximum temperature that occur at a flow rate of 0.01 m/s was 43.5 °C.
