Abstract

The UMKM’s of soybean processing in Madiun is 100 in number. All of them are small home industries Most of the soybean processing businesses do not make use of good management system yet. Consequently, they  face so many problems and barriers to develop their businesses. One effort in the management system intended is concerned with supply control and determination of daily production, which will  influence  the  operation of those companies. It is due to the fact that the two aspects are closely related to the level of market demand. If the amount of production and the number of requests are not met or approached at a point, then there will be a loss. In Murni, one of the UMKM’s of soybean processing,  it frequently happens that the number of production is excessive or short compared to the market demand in the period of production. As a result, some of the soybean is not saleable, or market demand is not met. The data analysis indicates that the total need for raw materials of soybean per year is 85,403 kg. In connection with stock planning, the analysis using POQ method shows that reservation interval (T) is 4 periods ahead and requires a total cost of IDR 617,449,375 annually.

Abstract

For a manager or manager of an organization, risk is a threat / danger that may interfere with normal activities or stop a thing that has been planned. Risks generally occur in all areas, including the supply chain. The supply chain is the process of linking the process from the initial search of raw material sources or commodities to the stages of manufacturing, processing, storage, transportation to last delivery and consumed by the end consumer. Risk identification is done by qualitative method approach such as literature study, survey / questionnaire / interview with supply chain actors with reference to SCOR, AHP and ANP model, followed by descriptive analysis. From the risk identification result, there is risk taking to determine the priority of risk that is immediately mitigated. The risk-weighted approach is carried out with a quantitative approach such as FMEA, Fuzzy FMEA, FAMs, OWA, AHP, Fuzzy AHP and ANP.

Abstract

The inventory replenishment process in the warehouse becomes difficult if there is uncertainty. It can cause warehouse performance not to be as expected. The warehouse is an important part of the supply chain subsystem, which smooths the flow of goods from upstream to downstream throughout the system. This paper uses system dynamics modeling to analyze the replenishment of raw materials where there is randomness in availability and reliability and their effects on the delivery lead time of the fleet. The model obtained is much simpler but more robust when compared to the analytical-mathematical model or the discrete-events simulation. Tests on the model show that the model can behave as it should logically. Several experiments were conducted to see how fleet availability's reliability can affect the delay in receiving or delivery lead time. One interesting thing revealed is that reliability does not have to be 100%, but there is a certain minimum threshold for the system to perform well. This is different from availability, which must be 100%.

Abstract

This study aims to implement a learning design based on technological pedagogical and content knowledge (TPACK) on the concept of rotating object. The research subjects were students of class XII IPA SMAK Santo Bonaventura Madiun. The data were obtained from observations and student test results in completing the concept of rotating object. This research is a development research. Mathematics is still considered a difficult subject by some students. For elementary and middle school level mathematics, it is still possible to deliver it based on students' experiences in everyday life. For the senior high school level, the concept of rotating object is difficult to imagine because it requires a higher understanding. Therefore, it is necessary to design learning that can provide direct experience to students. TPACK is learning that uses a combined application of an education system that prioritizes technology and certain applications (content) in learning. In implementing TPACK-based learning, there are several things to pay attention to, namely aspects of pedagogy, content, and technology. The findings of this study indicate an increase in student learning outcomes in the rotating object concept

Abstract

Penelitian ini mengkaji analisis dan saran menggunakan teknik Overall Equipment effectiveness (OEE), Six Big Losses, dan Total Productive Maintenance (TPM) untuk meningkatkan kinerja mesin centrifugal di PT XYZ. Berdasarkan data operasional mesin periode September 2024, ditemukan bahwa nilai rata-rata OEE hanya menyentuh angka 66% yang berarti tingkat efektivitas mesin centrifugal saat ini masih jauh di bawah standar kelas dunia (85%). Untuk menentukan penyebab utama kerugian ini, analisis tentang Six Big Losses dilakukan. Temuan menunjukkan bahwa kategori penyebab utama ialah Equipment Failures (29,8%), Idling and Minor Stoppages (27%), dan Reduced Speed Losses (21,5%). Ketiga kategori ini diidententifikasi kembali menggunakan Fishbone Diagram dan Root Cause Analysis untuk menemukan akar penyebab dari kerugian. Hasil identifikasi ditemukan akar dari masalah ini antara lain disebabkan oleh gangguan elektromotor, van belt yang sering kendor bahkan putus, penyumbatan valve, dan penyebab kecil lainnya. Agar efektivitas mesin dapat ditingkatkan, maka direkomendasikan beberapa tindakan berdasarkan implementasi TPM. Tindakan yang direkomendasikan antara lain penyusunan jadwal untuk preventif maintenance, pelatihan operator dalam deteksi dini kerusakan, memasang sistem alarm, penerapan checklist inpeksi harian. Dengan adanya tindakan-tindakan ini diharapkan tingkat efektivitas mesin dapat meningkat hingga mencapai standar kelas dunia.

Abstract

Masyarakat pedesaan memilih kayu dan ranting sebagai bahan bakar kegiatan masak-memasak di dapur daripada menggunakan minyak atau bahan bakar lain. Namun karena asap yang ditimbulkan maka pemerintah menyediakan gas elpiji tabung sebagai pengganti bahan bakar kayu dan ranting tersebut. Biaya yang dikeluarkan menjadi bertambah karena gas tersebut harus dibeli, meskipun dengan harga subsidi. Sementara itu ketersediaan kayu, bambu dan ranting banyak tersedia di pedesaan. Cara yang dapat ditempuh ialah mengubah sampah kayu dan ranting menjadi arang. Acara ini diadakan untuk memperkenalkan teknologi reaktor pembuat arang dari bahan sisa-sisa kayu, bambu atau ranting-ranting dengan metode pirolisis. Reaktor dibuat dari drum bekas. Sudah banyak tercipta teknologi tepat guna yang terpublikasi di berbagai media sosial. Teknologi itu perlu diimplementasikan ke pihak yang membutuhkan. Di daerah Mojopurno banyak terdapat sisa-sisa kayu yang tidak terpakai yang umumnya dimanfaatkan secara sederhana sebagai kayu bakar di dapur. Panas yang diperoleh tidak maksimal. Banyak asap yang timbul berdampak tidak bagus bagi penghuni rumah, juga bagi bumi secara keseluruhan karena menambah emisi carbon. Dengan menjadikannya arang, maka pemanfaatan energi dapat maksimum, dan yang juga penting: nyaris tidak menimbulkan asap. Arang yang diperoleh dapat menjadi bahan bakar bersih di dapur, terutama bagi masyarakat di desa Mojopurno.

Abstract

In the batch process, the company uses the same process facilities to produce various types of products. This allows businesses to change production in response to changes in market demand. Batch processes are widely used in industry. In many cases, batch processes provide several benefits over continuous processes, especially when the industry wants to ensure and maintain the quality standards of its products. This paper proposes a behavioral model of a single-stage batch processing system, using the language of system dynamics. When run, the behavioral model will provide an overview of how the system behaves. The system dynamics language is a formulation of a system of ordinary differential equations that is extracted from the real system being studied, in the form of a stock and flow diagram. The computation of this diagram is further implemented using software. Because it is actually a calculus method, the system dynamics language provides output data much faster than discrete simulation modeling. In this paper, the system behavior modeled is mainly loading, processing and unloading activities. The verification results carried out by testing it on two different case examples show that the model can sufficiently describe the behavior of the conceptual system logically so that the model can enrich experimental tool options related to batch production processes in the future.
