Abstract

Inventory in a company has an important role in supporting the course of a production and sales process. If the inventory in a company is managed properly, the production and sales processes can run smoothly. Based on this method of meeting the needs that are applied, sometimes the inventory becomes out of control, because demand changes every time. In response to this problem, Gudang Blessing Mandiri requires a new method to control inventory to be more efficient and effective. One method of inventory control is a method that only brings in goods if they are going to do the sales process or if they have received orders from consumers or distributors. And cooperate or contract with several suppliers of goods in the long term. This method is called Just In Time (JIT). The results obtained after applying the Just In Time method to the Mandiri Berkah Warehouse, the total cost for Aqua 330 ml was Rp. 103,723 with a cost savings of Rp. 105,476, on Aqua 600 ml of Rp. 236,560 with a cost savings of Rp. 552,683 and at Aqua 1,500 ml Rp. 187,789 with a cost savings of Rp. 417,158.

Abstract

Penelitian ini bertujuan untuk : mengetahui pengaruh gelombang suara pada pembuatan bahan bakar alternatif biodiesel dari minyak jarak, disamping itu juga untuk mengetahui pengaruh waktu reaksi dan konsentrasi katalis heterogen dalam memperoleh produk biodiesel sebagai bahan bakar nabati. Penelitian dilaksanakan yang diawali dengan reaksi esterifikasi untuk menurunkan kadar free fatty acid dan dilanjutkan dengan reaksi transesterifikasi dengan pemanasan ultrasonik. Parameter kualitas produk yang dihasilkan antara lain ; bilangan asam. Densitas, viskositas, kadar air dan analisa gas chromatography.
SOSIALISASI PEMANFAATAN LIMBAH RUMAH TANGGA MINYAK GORENG BEKAS (MINYAK JELANTAH) UNTUK PEMBUATAN SABUN CUCI DI KELURAHAN REMU UTARA KOTA SORONG Umar Rusli Marasabessy; Nur Abu; Anif Farida

Abstract

Sosialisasi pemanfaatan Limbah Rumah Tangga Minyak Goreng untuk pembuatan Sabun Cuci merupakan sosialisasi yang bertujuan untuk memberikan pengetahuan dan pemahaman tentang pemanfaatan minyak goreng bekas atau minyak jelantah. Sosialiasai ini menggunakan metode ceramah dan diskusi serta pembagian kuesioner kepada warga untuk mendapatkan data primer yang terkait dengan Minyak Jelantah. Setelah dilakukan sosialisasi, komentar warga tentang pemanfaatan limbah Minyak Jelantah sangat baik. Warga dalam sosialisasi ini sangat responsive dan antusias dalam mengikuti sosialisasi dari awal sampai akhir. Hal ini dapat menjadi pertimbangan untuk dilaksanakan sosialisasi lanjutan sehingga warga mampu membuat sendiri baik secara perorangan atau pun kelompok dalam membuat sabun dari minyak jelantah.

Abstract

In the era of globalization or the world of free trade, competition in the industrial world is increasing rapidly, this causes business competition to increase. Seeing the importance of measuring every activity carried out by the company, an accurate measurement method is needed to be able to provide accurate information on the time needed and the efficiency of each product activity in meeting production targets to achieve profits. The Stopwatch Time Study method is a work measurement technique using a stopwatch as a means of measuring the time shown in the completion of an observed activity. From the measurement results, a standard time will be obtained to complete a work cycle, where this time will be used as a standard for completing work for all workers who will carry out the same work as that. To determine the standard time, first calculate the cycle time and the time normal considering the degree of adjustment and allowance. Based on the results of data processing and discussion, it can be concluded that the lowest normal time is for employee 2 with a time of 39.05 seconds. Employee adjustment factor 2 with a total adjustment of +0.12 and employee allowance factor 2 with a total allowance of 22.

Abstract

The purpose/objectives/aims of this research is to determine the effect of sound waves on the manufacture of alternative biodiesel from castor oil, besides that it is also to determine the effect of reaction time and heterogeneous catalyst concentration in obtaining biodiesel products as biofuel. This research was carried out which began with the esterification reaction to reduce free patty acid levels and continued with the trans-esterification reaction with ultrasonic heating. Product quality parameters produced include: acid number, density, viscosity, water content and gas chromatography analysis,
