Abstract

Untuk memproduksi masal speaker hendaklah kita mempersiapkan komponen Part to Part serta memasang Part tersebut sesuai dengan fungsinya masing-masing, Quality Control (QC) sendiri menjamin dan memastikan produk tersebut OK & REJECT, Quality Control (QC) mekanisme kerjanya berpedoman pada alat ukur dan sumber daya manusia (operator), untuk menjamin alat ukurnya berfunsi dengan baik maka setiap alat ukur baru baik beli dan buat baru maka di berlakukan peng-kalibrasian pada alat ukur, serta mengadakan pengecekan secara berkala untuk memastikan alat ukurnya dalam kondisi yang selama proses pengukuran Quality Control (QC)) terhambat dengan mengukur soft part (lembek) pada part conepaper dan jika itu terjadi maka kerugian biaya dan lost time .Untuk mengatasi kerugian biaya dan Lost Time, Quality Control (QC) berusaha  menciptakan suatu alat bantu JIG ID (Inside Diameter) yang terbuat dari stainless steel 304 dipilihnya bahan Stainless Steel karena terbilang cocok sebab Material Stainless Steel tahan teradap panas, tahan gesek dan tahan karat, sebab JIG ID (Inside Diameter) akan menerima gesekan berulang-ulang dan harus tahan terhadap temperatur yang dingin dan panas pada waktu proses pengukuran.Terciptanya ide pembuatan JIG ini juga di pengaruhui faktor sumber manusia sebab pengukuran operator satu  dengan yang lainnya lainnya tidak sama dikarenakan faktor tekanan, maka ide yang tercipta untuk menyiasati faktor tekanan yang timbul itu adalah dengan menggunakan gravitasi (benda kerja dijatuhkan kebawah) sehinga didapatkan hasil pengukuran yang sama pada setiap operator .Hasil yang didapatkan pada kedua pengukuran dapat dilihat bahwa penggunaan JIG ID (Inside Diameter) paling sempurna dengan nilai Ø60.50mm

Abstract

This study is based on the need to make pumpkin as an alternative in food diversification through the role of business people. The initial strategy was to approach mapping the actors in the pumpkin agriculture sector from upstream to downstream. The aim of this research was to map the supply chain management of pumpkin in pumpkin production centers in East Java. This research used qualitative methods and participatory approaches. Data collection was done through in-depth interviews, observation, and study of documents and data. The results showed that the management of pumpkin supply chain in East Java had a structure, mechanism, and institutional pattern. The existing structure was formed through the role of 9 (nine) business operators in the pumpkin agriculture sector. Information flow occurs in two directions in the form of information on the quality and quantity of pumpkin harvested, the market price of pumpkin, previous collaboration experience, products that have been produced from pumpkin, pumpkin distribution schedule, and product innovations that have been produced from pumpkin harvest. Financial flow was carried out in the form of cash and credit between business actors. The product flow is in the form of fresh pumpkin products to semi-processed products such as pumpkin chips and pumpkin flour. Based on the supply chain flow patterns, the interwoven relationships that occur are vertical/horizontal as well as trade and partnership patterns.

Abstract

Sampah plastik masih menjadi masalah yang tidak dapat disepelekan sampai saat ini. Banyak upaya yang dilakukan untuk menangani permasalahan tersebut. Hingga saat ini proses pirolisis sampah plastik masih terus diteliti. Pirolisis adalah proses konversi sampah plastic menjadi bahan bakar minyak melalui proses pemanasan pada suhu tinggi tanpa oksigen. Selain menghasilkan minyak, proses pirolisis juga menghasilkan zat padat dan gas buang. Pada gas buang pirolisis masih mengandung CO2 yang tinggi. CO2 merupakan zat pengotor yang dapat menurunkan nilai kalor. Tujuan dari penelitian ini yaitu untuk memaksimalkan proses purifikasi gas buang pirolisis. Proses purifikasi dibagi menjadi dua bagian yaitu absorber dan adsorber. Absorber adalah penyerapan menggunakan zat cair(larutan) sedangkan adsorber adalah penyerapan menggunakan zat padat. Pada penelitian kali, purifikasi menggunakan bahan larutan NaOH sebagai bahan absorber, dan bahan adsorber menggunakan steel wool, zeolit, arang aktif, dan silika gel. Sedangkan untuk proses pirolisis menggunakan plastik jenis LDPE (Low Density Poly Ethylene) yang sudah dicacah.

Abstract

The working system of the heating process on a plastic injection molding machine needs to be considered in more detail. Due to the influence of temperature and the type of material according to the quality of the product. In this study, the plastic injection machine that used a temperature variation used several different variations, and three experiments were given at each temperature variation of 200°C – 250°C using 75 grams of plastic material with a heating time of 120-141 seconds and 150 grams of plastic material with a heating time of 120-141 seconds. Warm-up 210-250 seconds. Temperature control using the REX C100 Controller. The injection machine can operate according to the design. Namely, the heating temperature can be adjusted. Implementation and control of the control system show a good response. The plastic to be melted is of the HDPE (High-Density polypropylene) type with a temperature for melting the plastic of 250°C.

Abstract

The food drying process is an innovative method to change the process of reducing the water content of fresh food products of plant origin to slow down the emergence and growth of unwanted microorganisms. This heating system has four heating elements, where the heating elements used have a power of 1200W because each heating element has a power of 300W. During the drying process, it is known that the average air temperature in the drying room is higher when using solar energy compared to a heating system. The average temperature measurement during the day is 38°C. The measurement results tend to be constant, with an average of 34°C for 7 hours using the heating system. The battery voltage shows an increase every hour. At 08:30 am the battery voltage was 12.3V, and until 16.00 the voltage was 13.57V. This dryer is sourced from solar energy because using solar for drying requires a longer time, namely 8 hours (08.30-16.00), compared to using a heating system for 7 hours.

Abstract

Geographically, Indonesia is an agricultural country. It greatly supports agricultural production. So that the quality and commodity of agricultural products (soybean) remains high, it is necessary to have new ideas or ideas, one of which is by processing tempeh chips to become quality. It prompted researchers to develop innovative equipment that can speed up the tempe chopping process by creating an appropriate technology machine that can produce more optimal chopped tempeh compared to the conventional method, which is 30 kg/hour. This appropriate technology machine is implemented in UKM chips tempeh, Sukomanunggal sub-district, Surabaya City. The machine can help speed up the process of chopping tempeh so that production time can be optimally increased.
