Abstract

Being in an active fire lane means that Indonesia has geothermal potential. The geothermal research location is in the Tempuran area, Magelang Regency. The method used is by using alignment in the National Digital Elevation Model (DEMNas) data and calculating it using the Fault Fracture Density (FFD) method, the result of which is a contour map. This research aims to identify the existence of geothermal manifestations with FFD values. The research results show that the FFD value in the Tempuran geothermal manifestation area varies between 0.09 - 1.80 km/km2. The FFD value shows that the Tempuran geothermal manifestation is in a low density zone. There is no direct correlation between the presence of geothermal manifestations and the FFD value. The Tempuran geothermal manifestation is thought to be related to geological formations composed of volcanic rock and related to an aquifer system, as well as faults that trend northwest-southeast.

Abstract

Industri pastry dan bakery terus berkembang, terutama dalam aspek estetika produk. Salah satu yang populer adalah royal icing cookies, yakni kue kering yang didekorasi dengan royal icing dan memiliki tampilan menarik. Permintaan tinggi untuk desain musiman menimbulkan tantangan dekorasi yang memakan waktu dan berisiko menyebabkan pemborosan bahan, terutama saat tekstur icing tidak konsisten atau terjadi kesalahan desain. Penelitian ini bertujuan mengevaluasi efektivitas produksi royal icing cookies melalui penggunaan bentuk dasar (based) sederhana dan alternatif desain fleksibel. Metode yang digunakan adalah observasi langsung dan dokumentasi produksi di Tortern Bite & Taste. Hasil menunjukkan bahwa penerapan bentuk dasar seragam serta desain siap pakai dapat mempercepat dekorasi, mengurangi pemborosan bahan, dan meningkatkan efisiensi kerja. Penelitian ini menjawab tantangan produksi kreatif yang menuntut kecepatan, kreativitas, dan efisiensi sumber daya

Abstract

Ngawi is one of the areas in East Java province with an area that has topographic variations in the form of lowlands and highlands, because of its location on the slopes of Mount Lawu. There are several areas in Ngawi Regency that have the potential to be prone to landslides, which were then identified as suitable between the landslide hazard map which was derived from combining rainfall parameters, slope slope and geological conditions. Next, the landslide hazard map was compared with the FFD map produced from DEM (Digital Elevation Model) alignment analysis. The resulting landslide map is in accordance with the FFD map produced, namely in Sine sub-district, Ngrambe sub-district, Jogorogo sub-district and Kendal sub-district.
