Proprioceptive sensor data, including inertial measurement units (IMU), joint encoders, and torque sensors, plays a critical role in state estimation for quadruped robots operating in dynamic and unstructured environments. However, these signals are often degraded by various sources of error, such as high-frequency noise, bias, drift, and contact-induced disturbances, which directly affect estimation accuracy and stability. This study presents a systematic analysis of sensor-specific noise characteristics and evaluates the effectiveness of preprocessing methods tailored to each sensor modality. Specifically, moving average filtering is applied to encoder signals to mitigate noise amplification during differentiation, while first-order low-pass filtering is employed for IMU and torque signals to suppress high-frequency noise. Experimental results on a publicly available quadruped dataset demonstrate that encoder velocity RMSE is reduced by 12.09%, high-frequency energy decreases by 59.63%, and signal-to-noise ratio (SNR) improves by 145.6%. However, variance reductions remain limited (3.39% for IMU and 4.05% for torque), indicating the persistence of impulsive, non-Gaussian noise caused by contact events. These findings highlight that linear preprocessing methods are effective for attenuating high-frequency noise but insufficient for handling non-Gaussian disturbances. The study provides practical insights into the effectiveness and limitations of preprocessing strategies, serving as a foundation for developing more robust signal processing and state estimation frameworks in quadruped robotics.

Sweet corn is a high-value horticultural crop with steadily increasing demand for both fresh consumption and use as a raw material in the food industry. This study aims to evaluate the effectiveness of NPK 16-16-16 fertilizer on the growth and yield of sweet corn. The research was conducted at Sindangbarang Experimental Field, Faculty of Agriculture, IPB University from July to October 2025. This experiment used a Randomized Complete Block Design (RCBD) with a single factor, namely the dose of fertilizer application. Treatments were using fertilizer dosages of 0, 50, 0,75, 1,00, and 1,50 NPK 16-16-16, with a control treatment for comparison. During the vegetative phase, sweet corn exhibited similar growth responses across all fertilization levels relative to the control. However, all fertilizer doses significantly improved stover weight, cob weight with and without husk, cob length, cob diameter, yield per plot, and overall productivity compared to the control. The application of NPK 16-16-16 fertilizer at the recommended (1.0) rate achieved the highest relative agronomic effectiveness (103.11%), corresponding to a 1.03-fold yield increase over the control and outperforming the comparison treatment. Application of NPK 16-16-16 at the 1.0 recommended dose is suggested as the most efficient fertilization strategy for sweet corn production, as it maximizes yield and productivity without unnecessary increases in fertilizer input.     

This study evaluated the effects of compound and single-nutrient fertilizers on the growth and yield of cabbage (Brassica oleracea L.). The experiment was conducted using a randomized complete block design with seven fertilization treatments, including varying doses of compound fertilizer and a single-nutrient control. Results showed that the application of a 1.0× dose of compound fertilizer significantly improved plant height at 3 and 4 weeks after transplanting (WAT), and increased leaf number at 5 WAT. Yield components, including yield per plant, per plot, and hectare, were significantly higher in the 1.0× treatment, with an average yield of 1.92 kg per plant—an increase of 86.4% and 11.6% compared to the control and single-nutrient treatments, respectively. The relative agronomic effectiveness of the 1.0× dose reached 139%, indicating superior performance over the standard fertilizer. Economic analysis confirmed its viability, with the highest benefit-cost ratio (R/C) of 2.23 and a net profit of IDR 14,487,900. These findings suggest that compound fertilizer is both agronomically effective and economically profitable. The recommended application rate for cabbage is 211 kg/ha, applied one week after transplanting.

Global economic uncertainty and exchange rate fluctuations pose significant challenges to monetary stability in Indonesia, particularly in maintaining a controlled inflation rate. This study aims to analyze the transmission mechanism of the rupiah exchange rate to the inflation rate in Indonesia from 2015 to 2024. The method used in this study is library research by collecting, reviewing, and synthesizing data from various scientific literature, official central bank reports, and related journal articles published over the past decade. The research findings indicate that rupiah depreciation has a significant influence on rising inflation through the imported inflation channel, where currency depreciation increases the cost of raw materials for industries dependent on foreign markets. Furthermore, the findings reveal that the effectiveness of this transmission is influenced by public expectations and monetary policy taken by Bank Indonesia through adjustments to the benchmark interest rate. The implications of this study emphasize the importance of synergy between a stable exchange rate policy and controlling the supply of domestic goods to minimize the impact of external shocks on public purchasing power. The government and monetary authorities are advised to continue strengthening foreign exchange reserves and encouraging the use of local currencies in international transactions to reduce dependence on the United States dollar and maintain national price stability.

Bronchopneumonia is a type of infection of the lower respiratory tract that often occurs in children, especially toddlers. This disease is characterized by inflammation of the bronchioles and lung tissue which triggers increased production of secretions in the airways. The buildup of secretions often causes nursing problems in the form of ineffective airway clearance, which is indicated by ineffective coughing, rapid breathing, shortness of breath, and the appearance of additional breath sounds such as rales. Chest physiotherapy in children was carried out to evaluate the effectiveness of the clapping technique in helping to clear the airway in bronchopneumonia patients. The method applied in evidence-based practice (EBP) uses case studies with a nursing care approach. Intervention was given to three patients with a diagnosis of bronchopneumonia for three days, with a duration of approximately 1-2 minutes in each area of ​​the chest. Evaluation is carried out using a stethoscope and measuring time (clock), with the results recorded on an observation sheet. After chest physiotherapy (clapping), the three patients showed improvement in airway clearance, which was indicated by respiratory frequency returning to normal, no additional breath sounds (ronchi), and reduced secretion production. Based on these results, it can be concluded that the application of EBP through chest physiotherapy is effective in increasing airway clearance in bronchopneumonia patients.

This literature study examines the process of self-regulation in transforming compliance with school rules originating from external pressure into behavioral regularity emerging from personal awareness, and its impact on the effectiveness of student learning outcomes. Using a qualitative approach with content analysis method, this study synthesizes relevant literature to build a theoretical framework on how self-regulation facilitates the internalization of disciplinary values. The findings reveal that self-regulation occurs through a series of interconnected stages including goal setting, strategy planning, self-monitoring, evaluation, and adjustment. The success of this process is determined by internal motivation, appropriate environmental support, positive direct experiences, and healthy emotional management. Strong self-regulation directly impacts learning outcome effectiveness through improved cognitive strategies, strengthened intrinsic motivation, enhanced time and environment management, and developed capacity to constructively cope with failure. Learning outcomes achieved through self-regulation processes are characterized by lasting understanding, knowledge transfer ability, and the formation of lifelong learning dispositions. Schools and teachers play strategic roles in strengthening self-regulation through curriculum design that supports autonomy, formative feedback, role modeling, and collaboration with parents. This study contributes theoretically by positioning self-regulation as the central mechanism bridging external influences and internal disposition formation.

This study is grounded in the observation that the implementation of an efficient, simple, and low-cost judicial process in civil cases remains ineffective, particularly in relation to mediation as a dispute resolution mechanism. Although mediation has been incorporated into judicial proceedings with the aim of expediting case resolution, simplifying procedural stages, and reducing litigation costs for the parties, these objectives have not been fully realized in practice. This research seeks to examine the extent to which mediation in civil litigation effectively contributes to the realization of an efficient, straightforward, and affordable justice system. In addition, it aims to identify the factors that influence both the success and failure of the mediation process. The study employs a normative legal research method, utilizing statutory and conceptual approaches. The research is conducted through a literature review of primary and secondary legal materials. The findings indicate that the implementation of mediation in civil courts has not yet reached an optimal level. This is reflected in the relatively low success rate of dispute resolution through mediation, as well as the tendency for mediation to be treated merely as a procedural formality. Several contributing factors include the lack of good faith from the parties, limited time allocated for mediation, and the suboptimal role of mediators.

The findings also indicate that the effectiveness of storytelling is closely related to the developmental characteristics of elementary school students who learn better through concrete, imaginative, and engaging experiences. Furthermore, the implementation of storytelling through systematic stages pre-listening, while-listening, and post-listening can enhance students participation and comprehension during the learning process. In conclusion, storytelling can be considered an effective instructional strategy for improving English listening skills among elementary school students while also supporting vocabulary development and creating an engaging learning atmosphere.

This research is prompted by legal complications within civil procedural law, specifically regarding the failure of judges to identify formal defects in special powers of attorney during the preliminary stages of trial. The central focus of this study examines Decision Number 14/Pdt.G/2025/PN Kba, in which a lawsuit was declared inadmissible (Niet Ontvankelijke Verklaard) only after a seven-month litigation process that had already progressed through evidentiary hearings and local inspections. The objective is to evaluate the effectiveness of the dominus litis principle in empowering judges to provide procedural guidance for lawsuit amendments, while testing its alignment with the principles of simple, fast, and low-cost justice. Employing a normative legal research method with statutory and case-based approaches, the legal materials are analyzed qualitatively using the legal syllogism technique. The findings indicate that the application of the dominus litis principle in the a quo case remains ineffective due to the judges' passive and formalistic tendencies. Such an approach neglects the ex-officio authority mandated under Articles 119 and 132 of the HIR. This ineffectiveness results in significant judicial inefficiency, causing undue loss of time and financial resources for justice seekers. Consequently, this study recommends strengthening rigorous initial screening mechanisms by the panel of judges at the first hearing. This preventive measure is essential to curb the waste of judicial resources and ensure the realization of substantial justice for all disputing parties.
