Abstract

The Kutai Kartanegara Regency Government has launched the KUKAR IDAMAN Dedication Program (Innovative, Competitive, and Independent Kutai Kartanegara) as part of the 2021-2026 RPJMD, aimed at infrastructure development and economic empowerment. Loa Kulu, as the largest fish-producing area in East Kalimantan, plays a vital role in the development of the fisheries sector, particularly in tilapia aquaculture, which is recognized through the Regulation of the Minister of Marine Affairs and Fisheries. Despite its significant potential, tilapia aquaculture faces challenges such as limited capacity among fish farmers, weak regulatory enforcement, and high production costs. This study aims to identify appropriate strategies for developing tilapia aquaculture using qualitative methods, including observation, interviews, and documentation. Analysis is conducted using the SWOT approach and local economic concepts to support the implementation of the KUKAR IDAMAN program, with the hope of enhancing the effectiveness and sustainability of aquaculture efforts in the region.

Abstract

Food security is one of the most important things for a country, including Indonesia. This study aims to explain the various factors or constraints of land use, the optimization that has been or is expected from land managers, and the resulting implications at the Panca Arga Kesatuan dormitory at the Magelang Military Academy. The method used was a qualitative survey with in-depth interviews using purposive random sampling and data triangulation for analysis. In land use there are factors that hinder such as expensive fertilizer prices, unstable selling prices, different land forms, availability of infrastructure, pests and knowledge for each cultivator. Land cultivators also do various things to optimize their yields by joining the farming community in the area around the Panca Arga Military Academy dormitory, prioritizing selling crops to residents of the Panca Arga Unitary Military Academy dormitory, attending counseling or discussions about agriculture from people who are competent in the field prepared pesticides and build adequate infrastructure. The benefits that land cultivators get are numerous, such as being closer to other members of the soldiers, increasing their income, and also maintaining their health while not serving as soldiers. The Magelang Military Academy Unity and the community also benefit from the use of the land.

Abstract

Pencemaran air di wilayah perairan pesisir Pantai Selatan Bantul Yogyakarta tidak hanya berdampak kepada makhluk hidup tetapi juga menimbulkan korosi pada kontruksi baja sehingga umur pakai material baja lebih singkat dan nilai ekonomis menurun. Mayoritas logam pada industri maritim adalah Baja ASTM A36 dengan kandungan karbon 0,25% sampai 0,29%. Tujuan penelitian ini untuk mengetahui variasi waktu perendaman terhadap laju korosi Baja ASTM A36. Medium perendaman menggunakan dua variasi yaitu medium NaCl 3,5% (medium air laut buatan) dan medium NaCl 3,5% + H2SO4 0,5 M. Variasi waktu perendaman digunakan 24, 48, dan 72 jam. Secara eksperimental, hasil uji immersion corrosion test menunjukkan nilai laju korosi tertinggi Baja ASTM A36 pada rendaman medium NaCl 3,5% + H2SO4 0,5 M dengan nilai 37,584 mmpy (24 jam), 31,965 mmpy (48 jam), dan 23,795 mmpy (72jam), sampel uji mengalami korosi seragam dan korosi batas butir. Nilai laju korosi tertinggi pada medium perendaman NaCl 3,5% terjadi pada Baja ASTM A36 dengan nilai 0,098 mmpy (24 jam), 0,105 mmpy (72 jam), 0,081 mmpy (120 jam), 0,063 mmpy (168 jam), sampel uji mengalami korosi seragam dan korosi sumuran. Hasil penelitian didapatkan adanya senyawa H2SO4 dapat mempercepat laju korosi di lingkungan laut.

Abstract

Disaster logistics distribution requires a system that is fast, efficient, and adaptive. This study aimed to examine the effectiveness of the Saving Matrix algorithm in optimizing relief distribution routes during emergency operations of the Merapi eruption in Magelang Regency. The method employed was a comparative study between conventional distribution routes and routes generated through the Saving Matrix algorithm, using secondary data including distance, vehicle capacity, and terrain risk index. The findings revealed that the Saving Matrix algorithm reduced travel distance by more than 20% and accelerated distribution time. Moreover, the algorithm showed flexibility in adjusting to dynamic terrain conditions. This research concludes that the Saving Matrix method is not only theoretically relevant in the context of the Vehicle Routing Problem (VRP) but also practically applicable in disaster logistics distribution systems requiring high efficiency.
