Abstract

The current industrial implementation process is required to be carried out efficiently and environmentally friendly, this can be done with the presence of a heat exchanger. However, heat exchangers in the production of aluminum nitride nanoparticles are still rare. The purpose of this research is to analyze and improve the heat exchanger design in the production process of aluminum nitride nanoparticles at low cost. The heat exchanger can be designed based on several parameters of the TEMA standard by dimensional specification and specifications of hot and cold fluids. The method is calculated using a Microsoft excel application to evaluate the heat exchanger design according to the TEMA standard. The results showed that the shell and tube heat exchanger was designed with 39 tubes and an effective value of 85.72%. These results have met the TEMA standard and it is hoped that the design and evaluation of this heat exchanger can be used as a reference in the aluminum nitride nanoparticle production industry.

Abstract

Curriculum changes become the realization of ideas and the design of a learning process that emphasizes aspects of knowledge, skills and attitudes. SMAN 1 Mertoyudan implements several curricula in processing its grades which have been adjusted to Kemendikbud decisions. Currently, the scoring system is still done manually and processed by the homeroom teacher so that student guardians have difficulty monitoring children's grades during the teaching and learning process. Therefore, it is necessary to have a value monitoring system that can be accessed by student guardians online so that student guardians can find out from an early age student learning achievements. The monitoring system also provides easy access for subject teachers and homeroom teachers to manage grades, find out student learning achievements and provide assistance to students through student guardians. The system is designed to have a responsive display so that it is easily accessible from smartphones and laptops according to the web view on devices used by student guardians. This research builds a school academic monitoring system using a web-based dashboard. The results of the tests that have been carried out show that the user satisfaction level is 87.5% which can be concluded that users feel that the system created is easy to understand and understand.

Abstract

Social media as a means of communication can also be a place for branding, entrepreneurship and marketing. Various apps are very easy to access including online dating apps. The Tinder app is an online dating platform that came into existence in 2012 and has the highest percentage in 2022 compared to other online dating apps. Communication plays an important role in the message exchange that occurs in the Tinder app. The established communication patterns will affect the first impression when meeting in the media. Every human being has expectations of non-verbal messages or behaviors from others. This study aims to analyze the theory of violation of expectations of tinder app users as a communication intermediary to establish relationships. This study used a qualitative descriptive method by conducting structured interviews with active users of the Tinder application. Interviews were conducted to find out the informant’s perspective when using the application. Assumptions arising from the violation of expectations result in the non-occurrence of the same expectations. Based on the results of research, the tinder application is not only to find a partner but also can add relationships both in the world of lectures and in the world of work. Then, two out of three tinder app respondents managed to achieve expectations in using the tinder app.

Abstract

Education is very important along with the advancements in technology that required people to have in-depth and quality knowledge. A person who can get a job usually has a good educational background. How long it takes a person to get a job is affected by many factors. In statistical sciences, factors affecting how long a person gets a job after graduating from college can be studied using survival analysis. Survival analysis is a regression method used to examine the factors that influence the occurrence of one or more events. Several survival models can be used to estimate the impact of survival factors on how long a person gets a job, including the cox proportional hazard model and the accelerated failure time model. The cox proportional hazard model belongs to the semi-parametric approach where the hazard function essentially follows the non-parametric model while the independent variables follow the parametric model. The accelerated failure time model is a parametric model based on data distribution that can predict the time of the event in observed data. This study was conducted by comparing the cox proportional hazard model and the accelerated failure time model with the logistics distribution to determine if the conditions or data types are better identified with the cox proportional hazard model or the failure time model. time. The results obtained by considering the minimum AIC value, the accelerated failure time model has a better logistics distribution than the cox proportional hazard model.

Abstract

Sustainable agriculture plays a crucial role in achieving SDG 2 (Zero Hunger), SDG 9 (Industry, Innovation and Infrastructure), and SDG 12 (Responsible Consumption and Production). One strategic approach to achieving these goals is the utilization of solid organic fertilizers derived from biowaste, which can enhance soil fertility and strengthen food security. The effectiveness of such fertilizers is highly influenced by their macro- and micronutrient content, which must comply with national quality standards. This study analyzes the levels of phosphorus (P), potassium (K), and zinc (Zn) in three samples of solid organic fertilizer (PAP 01, PAP 02, and PAP 03) based on the Indonesian National Standard (SNI) 7763:2018, along with moisture content as an indicator of product stability. Phosphorus was analyzed using UV-Vis spectrophotometry, while potassium and zinc were measured using Atomic Absorption Spectrophotometry (AAS). The results showed moisture content ranging from 5.02% to 45.24%, P?O? from 1.47% to 4.00%, K?O from 1.58% to 2.86%, and Zn at 261.22 mg/kg, with good analytical precision (RPD and RSD < 5%). These findings indicate that solid organic fertilizers meet the minimum nutrient requirements for plant growth. The application of analytical chemistry in this study not only ensures product quality but also supports applied science innovation in promoting sustainable agriculture and community empowerment through science-based development.

Abstract

This study aims to evaluate the effect of biochar-based growing media on the growth of seedlings of three tobacco (Nicotiana tabacum L.) varieties—Jinten, Paiton-2, and Perancak-95—cultivated in clay-textured soil. Clay soil poses challenges for plant growth due to poor drainage and limited aeration, which can hinder root development and nutrient absorption. To address these limitations, biochar is used as a soil amendment, known to improve soil structure, enhance water retention, and increase nutrient availability. The experiment was arranged in a factorial Randomized Complete Block Design (RCBD) with two factors: tobacco varieties and seed soaking treatments (warm water, warm water with Azotobacter, and warm water with biohumic), each replicated three times. Observed parameters included plant height, leaf dimensions, stem diameter, root length and weight, and total fresh biomass. The results are expected to identify the tobacco variety that responds best to biochar treatment and provide recommendations for optimal seedling growth in marginal soils.

Abstract

This study aims to examine the physiological characteristics of seedlings from three national tobacco varieties (Jinten, Prancak 95, and Paiton 2) grown in biochar media under varying soaking treatments. Biochar, as a planting medium, has the potential to improve seedling quality and growth by increasing water retention capacity and soil nutrient availability. Seed soaking treatments were carried out using warm water, warm water + Azotobacter, and warm water + Biohumic to stimulate seed physiology. The Research employed a factorial Randomised Block Design (RBD) with two factors: variety and type of soaking, each repeated three times. The observed physiological parameters included the number of leaves, leaf length, plant height, leaf area, leaf colour, leaf area index, and total chlorophyll content, chlorophyll a, and chlorophyll b. The results showed that the combination of tobacco variety and soaking treatment significantly affected the physiological parameters of tobacco seedlings, both in vegetative growth and internal physiological content. The Prancak-95 variety (A2), treated with warm water + Azotobacter (D2), showed the best physiological performance in terms of plant height and leaf area. Meanwhile, the Jinten variety (A3) under the same soaking treatment showed the best leaf colour quality. In addition, the Paiton-2 variety (A1) with warm water soaking (D1) had the highest chlorophyll a content, indicating high photosynthetic activity. The combination of biochar media and biological soaking treatments effectively supported optimal seedling growth, as indicated by leaf morphology and chlorophyll content. This indicates that selecting superior varieties and appropriate soaking techniques plays a crucial role in enhancing seedling physiological efficiency and ensuring the success of sustainable tobacco cultivation.

Abstract

This study aims to evaluate the effectiveness of bioremediation using bio-fertilizers on the early growth of corn (Zea mays L.) in soil from former nickel mining sites. The study was conducted by observing soil characteristics and plant growth parameters, including soil texture, moisture content, cation exchange capacity (CEC), and macro nutrient content (N, P?O?, and K?O). Treatment L4P1 (location Sorowako with PGPR application) showed the best physical and chemical results, with the highest CEC value (40.65 cmol(+)/kg) and balanced macro nutrient content. Corn plant growth also showed a positive response to this treatment, indicated by the number of leaves (4.67), plant height (39.70 cm), leaf length (29.51 cm), as well as higher dry and wet weights compared to other treatments. Treatment P1 generally provided the most consistent and superior results compared to P2 and P3, demonstrating the effectiveness of the microbial formula in improving soil quality. degraded. In contrast, the L5 treatment showed the lowest results on almost all parameters. These results indicate that bioremediation with biofertilizers, particularly using PGPR (P1), has great potential in reclaiming former nickel mining soils and supporting food crop productivity on marginal lands

Abstract

Local tobacco has an important role in the kretek cigarette industry in Indonesia, because 80% of kretek cigarettes are made using local tobacco. However, in some areas, the quality of local tobacco remains low due to inefficient fertilisation. Using slow-release fertiliser can increase the efficiency of nutrient uptake by plants. This Research aims to examine the use of biochar-based slow-release fertiliser on the morphological characteristics of tobacco plants. The Research method was a field experiment using a randomised block design to test the SRFbiochar SP36 fertiliser treatment. The treatments tested were SRFbiocharSP36 as basic fertiliser, SRF-BiocharSP36, SRF-biocharSP36+Cow urine and SRF-BiocharSP36+Cow urine+Azotobacter on tobacco morphological characters, including: plant height, number of leaves, stem diameter, flag leaf angle and wet weight of tobacco leaves. The Research found that SRF-BiocharSP36, used as a basic fertiliser, produced the best results and significantly affected plant height (68.60 cm) and stem diameter (19.39 mm). Apart from that, this formula gave the best results for the number of leaves (24) and the wet weight of leaves (44.92 g).
