Abstract

The agricultural sector faces significant challenges in managing abundant post-harvest residues that have not been optimally utilized. This study aims to design and develop a hammer mill-type agricultural waste shredder with a target capacity of 100 kg/hr to support farmer mobility in local agroclimatic regions. The methodology encompasses 3D model design, technical calculation analysis, and independent manufacturing using mild steel materials. Technical analysis results indicate a design power of 6.72 kW with a torque of 35,653.3 N-mm, powered by a 7.5 HP gasoline engine at 1,800 RPM. Functional testing on rice straw and corn stalks demonstrated operational stability with an actual production capacity reaching ±99.7 kg/hr. A slight mass reduction of approximately 3.5% in the final output was attributed to moisture evaporation caused by mechanical heat during the shredding process. This innovation provides a practical solution for farmer groups in accelerating organic decomposition and improving the efficiency of livestock feed provision.

Abstract

Large red chili (capsicum annuum L.)  is a herbaceous plant that has a spicy taste and is one of the types of chili that is most widely used by the Indonesian people, especially on a household scale by 61%. Therefore, increasing the production of large red chili needs to be done, one of which is through the administration of gibberellin and Local Microorganisms (MOL) from Batu banana corms. This study aims to determine the effect of administering gibberellin (GA3) and MOL from Batu banana corms on the growth of large red chili plants, determine the most effective concentration, and observe the interaction between the two. The study was conducted from February to March 2024 at the Botany Laboratory, FMIPA, University of Lampung, using a factorial Completely Randomized Design (CRD). The first factor was gibberellin with two concentration levels (0% and 10%), and the second factor was MOL from Batu banana corms with three concentration levels (0%, 10%, and 20%) with five replications, resulting in 30 experimental units. The parameters observed included plant height, root length, fresh weight, dry weight, relative water content, chlorophyll content, and leaf visualization. Data were analyzed using ANOVA followed by a 5% Tukey test. The results showed that the combination of 10% GA3 and 20% MOL affected fresh weight, dry weight, and chlorophyll a, b, and total, while the control affected plant height, root length, and relative water content.

Abstract

"Sayu Rasa" Crackers MSME faces productivity constraints due to suboptimal production facility layout, resulting in long material handling distances and inefficient production time. This study aims to optimize the production layout to minimize material handling distance and improve production process efficiency. The method used is Systematic Layout Planning (SLP) through stages of material flow analysis, from-to chart creation, activity relationship diagram design, layout alternative development, and evaluation using weighted factor analysis. Implementation results show a 39.1% reduction in material handling distance (from 128 meters to 78 meters per production cycle) and a 20% productivity increase (from 50 kg/day to 60 kg/day). Production time decreased by 15.5% from 420 minutes to 355 minutes for the same production capacity. The research conclusion proves that the application of industrial engineering principles through SLP method effectively improves MSME operational performance with minimal investment.

Abstract

Red chili (Capsicum annuum L.) is an important horticultural crop that is widely used as a cooking spice. However, this fruit has a short shelf life and is susceptible to Colletotrichum sp. infection which causes anthracnose disease. One effort to extend the shelf life and suppress fungal infection is the use of natural coatings. Sweet orange peel(Citrus aurantium L.) which contains pectin has the potential to be used as a base material for natural coatings to increase the resistance of red chili. This study aims to determine the effect and determine the effective concentration of natural coatings from sweet orange peel on the quality of red chili and its resistance to Colletotrichum sp. The study used a Completely Randomized Design (CRD) with six treatment concentrations: 0%, 1%, 2%, 3%, 4%, and 5%, each repeated four times. The parameters observed included texture, weight loss, incubation period, disease incidence, disease severity, and number of conidia. The results showed that a concentration of 5% gave the best results in maintaining fruit texture and weight, extending the incubation period, and inhibiting disease development and reducing the number of Colletotrichum sp. conidia.

Abstract

Education at the Madrasah Ibtidaiyah (MI) level currently faces significant challenges in balancing cognitive mastery with holistic character building amidst moral crises and intolerance. This study aims to elaborate on the integration of the 2025 Love-Based Curriculum (KBC) and Howard Gardner's theory of Multiple Intelligences in Natural Science (IPA) learning at MI. The method employed is library research, using content analysis and descriptive-synthesis techniques on KBC policy documents and literature related to multiple intelligences. The results indicate that the synergy between KBC and Multiple Intelligences creates a holistic and inclusive science learning ecosystem. The "Panca Cinta" values are transformed through eight unique intelligence pathways, where scientific phenomena are understood as "kauniyah" verses that foster religiosity, empathy, and ecological responsibility. The novelty of this research lies in the interdisciplinary synthesis that maps emotional-spiritual intelligence onto the cognitive diversity of MI students. The study concludes that this integration not only improves scientific literacy but also serves as a catalyst for a more humanistic education through learning personalization based on AI technology and local wisdom.

Abstract

Bus accidents continue to contribute significantly to global transportation fatality statistics, particularly in developing countries where human factors and infrastructure conditions play a major role. A comprehensive synthesis of bus superstructure crashworthiness technologies is presented by tracing their evolution from basic regulatory compliance toward the challenges of future technological adaptation. While the UN ECE R66 standard has established a well-defined framework for rollover protection, a review of the literature reveals a substantial gap in frontal impact standards, leading to the adoption of truck regulations (UN ECE R29) that are often incompatible with the flat-front geometry of buses. The discussion focuses on recent findings related to validated virtual testing methodologies, innovative structural reinforcement strategies such as seat-to-pillar integration, and the critical role of occupant restraint systems in mitigating secondary injuries. Furthermore, the transition toward electric buses is identified as introducing new challenges associated with high-voltage battery protection and the brittle failure characteristics of lightweight composite materials. It is concluded that future safety paradigms must evolve beyond merely preserving occupant survival space toward a holistic approach that integrates structural optimization, occupant biomechanics, and energy storage system protection.

Abstract

Corn (Zea mays L.) is an important agricultural commodity. One of the limiting factors in corn cultivation is the presence of weeds such as Euphorbia hirta L. (Patikan kebo). The leaf extract of Euphorbia hirta contains allelochemical compounds such as phenols, alkaloids, saponins, and flavonoids that may inhibit seed germination. This study aimed to determine the effect of Euphorbia hirta leaf extract on the germination of corn seeds (Zea mays L.). The research used a Completely Randomized Design (CRD) with five concentration treatments (0%, 5%, 10%, 15%, 20%) and five replications. The observed parameters included germination percentage, germination rate, plumule length, radicle length, and vigor index. Data were analyzed using One-Way ANOVA followed by the LSD test at a 5% significance level. The results showed that Euphorbia hirta leaf extract significantly affected radicle length and vigor index, with the highest inhibitory effect observed at a concentration of 20%.

Abstract

Machining processes such as cutting, drilling, and grinding often leave burrs on workpiece edges that can reduce surface quality, disrupt assembly, and pose safety risks. Therefore, an effective and efficient finishing method is required to remove these burrs. This study aims to design a vibration deburring machine capable of removing burrs while improving the surface quality of machined workpieces. The design method includes a literature review and analysis of existing products as design references, identification of functional requirements and technical specifications, calculation of main components, and mechanical and frame structure design. The proposed vibration deburring machine is driven by a three-phase electric motor with a rotational speed of 3000 RPM and a power of approximately 1 kW. The deburring tank is designed with dimensions of 700 × 440 × 400 mm, enabling the processing of ten or more workpieces in a single cycle. The machine frame is constructed from ASTM A36 steel with a yield strength of 250 MPa. Structural analysis shows that under a maximum load of 300 kg, the highest stress in the lower frame reaches 69.5 MPa, which is well below the material’s yield limit. Based on these results, the designed vibration deburring machine meets operational and structural strength requirements. This design is expected to serve as an alternative solution and reference for vibration-based finishing machines in industrial manufacturing applications. The machine is suitable for small-scale manufacturing.
