Abstract

In order for the practicum to still be carried out, alternative practicum learning media are needed. An interactive application based on research of physics phenomena is PhET (Physics Education Technology) simulation. This study aims to determine the level of effectiveness of virtual basic physics practicum and the level of student understanding of basic physics courses through virtual practicum with PhET simulation. Interactive learning and allowing students to practice independently, limited practicum equipment facilities and inadequate laboratory space are the main contributing factors. In order to compare the differences in student learning outcomes between experimental and control courses, this study used a Pre test-Post test Control Group Design with one experimental class or treatment class and one control class to test the difference in student learning outcomes between experimental and control classes using data processing procedures using the True Experiment method. Based on the research, the effectiveness of using PhET simulation application media has an N-gain value of 0.66 and can increase understanding of lecture material by 52%.

Abstract

Konveksi XY merupakan unit usaha menengah yang bergerak di bidang konveksi atribut sekolah dan non atribut sekolah. Proses produksi konveksi XY menganut sistem make to stock, dimana konveksi membuat 250 set seragam (seragam putih, batik, pramuka, olahraga, almamater atau jas dan kerudung bagi siswi) untuk satu sekolah. Setiap sekolah yang menjadi pelanggan tetap, rentang pengerjaanya dimulai setelah ajaran baru berlangsung sampai sebelum pembukaan pendaftaran siswa baru. Pada rentang waktu tersebut, terdapat kasus penjahit dari kelompok kerja unit lain membantu unit kerja yang belum selesai. Hal ini mendorong peneliti untuk melakukan penelitian menggunakan metode Objective Matrix. Tujuan penelitian ini adalah untuk menganalisis dan mengukur produktivitas pada lini produksi seragam sekolah, menganalisis pengaruh produktivitas terhadap efisiensi dan efektivitas, dan menemukan solusi perbaikan berdasarkan hasil pengukuran produktivitasnya. Hasil penelitian ditemukan bahwa produktivitas di konveksi XY tidak stabil. Hal ini berdasarkan diagram pareto hasil performance indicator (PI) dimana alur kurvanya naik turun meskipun mayoritas nilai PI diatas standar (300) kecuali periode 8 (146). Kemudian diperkuat dengan diagram pareto hasil indeks PI dimana nilai indeks PI periode sekarang terhadap periode sebelumnya negatif, yakni : (1) periode 2 (-28,547); (2) periode 4 (-39,130); (3) periode 7 (-24,265); dan (4) periode 8 (-52,751) dan Indeks PI periode sekarang terhadap PI standar alur kurvanya naik turun dengan hasil negatif pada periode 8 (-51,333). Adapun produktivitas tidak mempengaruhi efisiensi dan efektivitas, tetapi efisiensi dan efektivitas yang mempengaruhi produktivitas. Kemudian perbaikan yang perlu dilakukan adalah memangkas kegiatan dan hal yang dapat menyebabkan pemborosan waktu.

Abstract

Perusahaan mengalami tidak tercapainya target produksi pada tahun sebelumnya. Hal ini membuat peneliti ingin melakukan pengukuran produktivitas untuk perusahaan, karena sebelumnya belum ada pengukuran produktivitas pada pabrik. Dalam pengukuran produktivitas kali ini peneliti menggunakan metode Objective Matrix (OMAX). Dalam pengolahan datanya peneliti menghitung nilai rasio tiap periode, nilai bobot, nilai level 0-3-10, nilai selain level 0-3-10, Indikator Performansi (IP), dan Indeks. Tujuan penelitian ini agar dapat mengetahui analisis dan pengukuran produktivitas pada home industri ini dan menemukan solusi untuk perbaikan berdasarkan hasil yang ditemukan. Dalam analisis menggunakan diagram Pareto didapat bahwa untuk mencapai dampak perbaikan 80% maka ditentukan rasio-rasio yang harus segera diperbaiki, yaitu rasio 2, 4, dan 6. Hal ini dapat ditingkatkan dengan berbagai usulan, yang pertama meningkatkan skill para tenaga kerja, dan mengupayakan para tenaga kerja dapat bekerja saat produksi bekerja, kemudian yang kedua melakukan proses maintenance secara rutin, lalu memberi alat penyedot suhu panas, untuk faktor mesin bisa membeli alat otomatis sehingga dapat mempercepat proses percetakan, dan menjalin hubungan dengan supplier bahan baku sehingga dapat memberikan bahan baku yang berkualitas.

Abstract

Abstract PT. XYZ is a sugar producing company with a production capacity of 12,000 TCD (Ton Cane per Day). To be able to compete with its more experienced competitors, PT. XYZ needs a proper strategy. One of these strategies is to maintain and continuously improve product quality, as well as other aspects in all lines of the company. Constraints that occur at PT. XYZ is a low boiler efficiency level, which is in the range of 65%-75%. This value is 10% lower than the standard efficiency of boilers that use coal as fuel. The purpose of this study is to increase the optimization of the use of boiler fuel at the company PT. XYZ. By using the FMEA method and the New Seven Tools, the problems causing wasteful use of fuel can be mapped thoroughly, making it easier to understand the root of the problem, as well as looking for targeted improvement suggestions. The result is that it is known that there are 7 problems related to optimizing the use of coal fuel at PT. XYZ. Among them are the problem of 'High coal humidity' with a waste of Rp 7,036,281,797 per year, the problem of 'Steam pipe leaking' with a waste of Rp 1,323,800,301 per year, and the problem of 'Sootblow Superheater and Economizer not optimal' with a wasted cost of Rp 349,490. 375 per year

Abstract

Abstract The supply chain is a network system of several interconnected organizations with the same goal of distributing production goods and services to their customers. PT. Samudera Gemilang Plastindo (PT SGP) is a company engaged in the processing of plastic seeds, one of the products produced is HDPE T-Shirt Bag. The supply chain system studied at PT. SGP consists of a Manufacturing (Vendor) and 3 Sales Offices (SIM Jember, Depo Bali and 3S Bogor) because they often experience inaccuracies in forecasting data which causes the Bullwhip Effect phenomenon or information distortion to meet customer needs. Initially, forecasting was carried out at each level of the supply chain using different forecasting methods and inventory planning was carried out separately and not coordinated with each other. Therefore, we need an equation in choosing a forecasting method to synchronize the forecasting results and the implementation of production in each supply chain actor. This study uses the Collaborative Planning and Replenishment (CPFR) method, which is a method that combines production planning, forecasting and inventory control. The results of testing several forecasting methods, the method chosen is the Winter's Method because it has the smallest error value. Inventory control is done by calculating the optimal lot, namely Economic Order Quantity (EOQ). The results of demand forecasting and determining the optimal lot are used to calculate the value of the Bullwhip Effect that occurs after the use of the CPFR approach in the supply chain at the vendor level (PT SGP) has changed from 1.285 to 0.729, while in the three Sales Offices there has been a change from 1.321 to 0.528 in SIM Jember sales office, 1.266 to 0.602 at Bali Depo sales office, 1.377 to 0.412 at 3S Bogor sales office.

Abstract

Abstract PT. XYZ is a private sugar factory in Lamongan Regency, East Java. The resulting product is sugar, besides that the sugar production process cannot be separated from liquid waste. PT. XYZ often has problems in the treatment of WWTP (Wastewater Treatment Plant) at the input in the BE pond (Equalization Tank). Influent in the BE pond (Equalization Tank) often occurs levels of COD (Chemical Oxygen Demand) that do not match the company's quality standards because the influent input is sometimes too large. The purpose of this study was to improve the quality of the influent product to match the company's quality standards with aspects of activated sludge utilization in BE ponds (Equalization Tank). The taguchi method is used as a method to improve and improve quality and analyze the factors that influence the quality of the influent, including the volume of activated sludge, the length of the aerator running, the volume of waste, the interval between activated sludge added and observed. Taguchi standard orthogonal matrix L8(27) used the objective function 'the value is getting smaller (closer to the desired 0)'. The results of the analysis of variance (ANOVA) obtained that the dominant factor affecting the quality of the influent was the volume of waste (C), while based on the Taguchi method, the most optimal experimental results resulted in a combination of 100 ml activated sludge volume, 5 hours aerator running time, 1 liter waste volume, the gap between activated sludge was added and observed for 5 hours.

Abstract

Cahya setya trophy is a small manufacturing industry that produces trophies, vandels, acrylics, etc. In this small industry in the warehouse, there is still a lack of awareness to use personal protective equipment and a work method that can cause Musculosketal disorders. This study aims to analyze K3 from the Cahya setya trophy warehouse using observation methods, Nordic Body Map, RULA and REBA. The observation method was used for the initial step of the study and the Nordic Body Map was used to find a sample as a research from the RULA, REBA method. The results of work safety observations found that the dangerous action if not wearing shoes was the worst possibility that it could cause the employee's feet to bruise, and not using gloves was the worst possibility that the hands could be scratched. The results of the occupational health analysis using the REBA method, the bent position got a final score of 8, the duct tape process squat position got 9 scores, both positions had an action level of 3, and the packaging squat position got a score of 12 with an action level of 4, which means there is a very high risk and this position is very dangerous, then change action is needed, The results of the RULA method in the packaging squat position, the duct tape squat got a score of 6 which had an action level of 3 and the bent position got a score of 7 which had an action level of 4. From the results of these calculations, all work methods require action to change work methods, if changes in work methods are not immediately carried out, it can trigger Musculosketal disorders and lack of comforted at work.

Abstract

UD Berkah Jaya Offset is one of the manufacturing companies operating in the field of cardboard box production. The company offers a variety of cardboard box products in various sizes, including sizes D1, D2, D3, trepes, and roll. In the production of cardboard boxes, particularly size D1, issues such as overstock and even stock shortages have been frequently encountered during the period from January 2022 to December 2023. This is due to the ineffective demand forecasting to anticipate these possibilities. This study aims to forecast the demand for size D1 cardboard boxes for the upcoming months using the best forecasting method. The methods employed are decomposition method, Winter's exponential smoothing, and Holt's exponential smoothing. This research compares the three methods based on the smallest Mean Absolute Percentage Error (MAPE) value. The results of the study reveal that the decomposition method is the most effective, with a MAPE value of 19, MAD value of 28000, and MSD value of 1247419480, indicating a low level of forecasting error compared to the others.
