This study aims to examine the implementation of Regional Regulation Number 4 of 2014 concerning the Protection and Empowerment of Farmers and Fish Farmers in Sidoarjo Regency. Focusing on Gisik Cemandi Village as the case study, this research employs a qualitative descriptive approach with Grindle’s policy implementation theory as the main analytical framework. The findings reveal that while various programs such as skill training, fuel subsidies, fishing equipment aid, and institutional strengthening have been carried out, there are still obstacles in equitable distribution, budget constraints, and continuity of the programs. Nevertheless, strong inter-agency coordination, responsiveness of the implementers, and active participation from the fishermen community contributed positively to the overall implementation. This study underscores the importance of aligning public policy with community needs to achieve sustainable development in coastal areas.

This research focuses on optimising precise Brushless DC (BLDC) motor speed control using a Proportional-Integral-Derivative (PID) controller. The fundamental problem lies in the performance of PID control, which is highly dependent on the accuracy of determining its gain parameters (Kp, Ki, Kd), where manual tuning methods often do not provide satisfactory results. Therefore, the objective of this study is to apply the Ziegler-Nichols systematic method to the PID control tuning process for BLDC motors and then evaluate the performance of the resulting system based on key response time parameters such as rise time, settling time, overshoot, and steady-state error. The proposed method involves designing a mathematical model of the BLDC motor and applying the Ziegler-Nichols technique, specifically the Ultimate Oscillation Method, to systematically derive the values of Ku and Pu which are then used to calculate Kp (5.1), Ki (22.7), and Kd (0.29). The main findings show a dramatic performance improvement in the BLDC speed control system after the implementation of the tuned PID; the rise time is significantly reduced from 0.3728 seconds (without PID) to 0.0041 seconds, the settling time improves from 0.6642 seconds to 0.0073 seconds, and most importantly, the steady-state error of 45.38% is eliminated to 0%.  The main idea synthesis is that the Ziegler-Nichols method provides an effective and practical approach to PID parameter optimization, resulting in a highly responsive, accurate and stable BLDC motor control system. In conclusion, this study successfully demonstrates that applying a PID controller with parameters determined via the Ziegler-Nichols method significantly improves the speed control quality of a BLDC motor, overcoming the steady-state error problem and substantially improving the transient response characteristics.

This study examines the comparative analysis of customary law and positive law in the context of harmonizing public policy in Indonesia. The main objective is to explore the characteristics of each legal system and their interaction in the formulation of inclusive policies. Customary law, rooted in traditional norms, plays a significant role at the local level, while positive law focuses on formal regulations applied at the national level. Through literature review and analysis, this research identifies key aspects of both legal systems and their contributions to the harmonization of public policy. The findings indicate that the integration of customary law and positive law can strengthen fair and inclusive policies at various levels of governance.

Pricing is an important component of marketing strategy and is essential for business sustainability. Cost Plus Pricing and Target Costing are the two most common techniques for determining selling prices. The purpose of this study is to compare the effectiveness of the two methods in determining the selling price of goods, especially considering the aspects of cost through documentation, interviews, and financial statement analysis. The results of the study indicate that Target Costing focuses on cost efficiency to achieve the desired market price, while the Cost Plus Pricing method tends to produce higher selling prices but is less competitive in the market. The results of the study indicate that the pricing method must be adjusted to the characteristics of the.

The purpose of this study is to examine how cost classification is used in management accounting and to what extent this information is used in the management decision-making process in manufacturing companies. Cost categories, such as fixed, variable, direct, and indirect, help managers understand the cost structure and assess operational efficiency. This study was conducted through a qualitative descriptive case study approach in one of the manufacturing companies in Indonesia. Direct observation, in-depth interviews, and internal company documentation were used to collect data. The results showed that, especially in budget planning, cost-volume-profit analysis, and selling price determination, proper cost classification plays a significant role in the decisionmaking process. However, some problems were found with the consistency of cost classification, which can affect the accuracy of management data.

Mathematical representative ability is a person's ability to express mathematical ideas, objects, and relationships in various forms of representation, both visually, symbolically, verbally, and contextually. This study aims to analyze the mathematical representative ability of students through counting operations in grade III elementary school in the form of story problems. The method used was descriptive qualitative research with written test instruments to assess cognitive abilities and observation to assess psychomotor skills. The research subjects consisted of five grade III elementary school students, by giving test questions on mathematical reasoning skills, observing students directly in solving and understanding story problems, conducting documentation to obtain accurate data when in the field by classifying students' mathematical representative abilities based on math scores. The results showed that most learners had a very good level of cognitive ability in completing arithmetic operations, but there were some learners who were still lacking in understanding story problems. This finding confirms that the importance of appropriate learning strategies so that learners are not only able to solve problems in the form of operations but also able to understand problems in the form of story problems that are applied in real life.

Penelitian ini bertujuan untuk mendeskripsikan dan menganalisis penyelenggaraan pelatihan kepemimpinan pengawas dan efektivitas penyelenggaraan pelatihan kepemimpinan pengawas tersebut dalam masa pandemi covid-19 di lingkungan Pemerintah Kota Salatiga. Penelitian ini menggunakan metode penelitian kualitatif. Model analisis data yang digunakan adalah model analisis Interaktif Miles dan Huberman. Kesimpulan dari penelitian menunjukkan bahwa penyelenggaraan pelatihan kepemimpinan pengawas dalam masa pandemi covid-19 di lingkungan Pemerintah Kota Salatiga belum efektif karena metode penyampaian yang digunakan hanya metode ceramah, koneksi internet yang kurang stabil dan pengawasan yang dapat dilakukan panitia dan widyaiswara hanya dengan melekat di zoom masing-masing peserta. Saran yang dapat diberikan terkait hasil penelitian ini adalah metode penyampaian yang digunakan hendaknya variatif dan disisipkan ice breaking agar peserta tidak bosan, disiapkan gedung khusus dengan koneksi internet yang stabil, peserta dikumpulkan di satu titik lokasi untuk mempermudah pengawasan yang dilakukan oleh panitia.
