Abstract

Daerah Istimewa Yogyakarta (DIY) mempunyai potensi industri yang cukup tinggi, baik industri kecil, menengah, maupun besar. Namun daya saing produk industri pengolahan di DIY rendah karena beberapa faktor, yakni masih lemahnya keterkaitan antar industri, keterbatasan produksi barang setengah jadi dan komponen di dalam negeri, keterbatasan industri berteknologi tinggi, kesenjangan kemampuan ekonomi antardaerah, serta ketergantungan ekspor pada beberapa komoditas tertentu. Penelitian ini bertujuan untuk membuat rancangan konsep kawasan industri berbasis potensi daerah (Domestic Based Industry/ DBI) menggunakan pendekatan sinergi Academic-Business-Government (ABG). Pendekatan ini dilakukan dengan fokus pada pemanfaatan bahan baku, sumber daya manusia, dan pemenuhan permintaan pasar lokal. Hasil kajian ini menghasilkan tiga konsep kawasan DBI yang diusulkan: (i) pengolahan produk turunan salak pondoh di Turi Sleman, (ii) pengolahan zeolit di Gedangsari Gunungkidul, dan (iii) pengolahan limbah produk biogas di Cangkringan Sleman. Ketiga konsep kawasan industri pengolahan tersebut saling terkait dan akan membentuk jejaring yang terintegrasi mulai dari bahan baku hingga produk, baik dengan industri rancangan baru maupun dengan industri yang sudah ada.

Abstract

The high production of salak pondoh in Sleman Regency is not in line with the welfare of the farmers. The farmers receive a low price during the main harvest season, where the selling price per kilogram drops below the cost of production, so that the profit margins of farmers are not met. Abundant production during the main harvest and characteristics of perishable fruit are the cause of this problem, so that most farmers sell their crops to the nearest traders. This condition makes the bargaining position of farmers weak and the price determined by the traders, thus impacting on the decline in their welfare level. The purpose of this study is to formulate the salak pondoh business model in Sleman Regency in the form of dynamic simulations to carry out various scenarios of procuring business products based on raw materials in the form of fruit and waste from salak pondoh. The results of this simulation are expected to provide an alternative picture of solutions, steps, and conditions for academics, business people, and government in the form of a simulation template for each scenario. Data collection was carried out through direct observation to the salak pondoh place of business in Sleman Regency, brainstorming, interviews with related parties such as the salak pondoh association and the Sleman District Agriculture Office, and secondary data documentation on research topics. Scenarios of derivative business procurement (fruit and waste-based raw materials) provide a significant increase in income compared to business as usual business conditions, ranging from 4% - 44% in various fractions tested and up to 293% in extreme conditions and able to reduce the number of unemployed in Sleman Regency. The scenario of supplying derivative business made from pondoh salak fruit provides a significant increase in income compared to procurement of derivative business made from pondoh salak plant waste. It takes a probability value of sales of derivative products of more than 48.97% so that the revenue value from the business procurement scenario is greater than business as usual

Abstract

Seawater is one of the largest natural resources and abundant in Indonesia, which contains salt, metals and mycobacteria. Even though the amount is abundant, its utilization is still not widespread, such as to be used as clean water or drinking water. The use of adsorbents aims to adsorb impurities in the fluid. The adsorption column that is widely used is in the form of a fixed-bed column with messy stacked filling. This makes it difficult to clean and fill the adsorbent, besides the irregular pile of adsorbents will hinder the flow process of the purified fluid. The research product is a circulating portable adsorption column design consisting of 3 parts, namely: top distributor, packing bed, and bottom collector. The principle of the three parts is like a puzzle where the number of packing beds can be adjusted according to the purification needs. The three parts are connected with threads so that they can be disassembled as desired. It is hoped that this product can meet the needs of adsorption-based purification that is easy, inexpensive, and can be customized according to various types of adsorbents. The design of this product can be duplicated for other adsorption purification processes, such as purification of bioethanol, wastewater, and biodiesel.

Abstract

Production of horticultural crops in Sleman District is dominated by salacca-pondoh with total production in 2016 reaching 73 kton, cover up to 98% of total salacca-pondoh’s production in Yogyakarta Province. But salacca-pondoh’s farmers actually got very low-price during harvest season and they only act as a price taker that had low bargaining position, so that their welfare. This research formulated salacca-pondoh’s business as usual condition in Sleman District in form of system dynamic simulation. The factors influenced the low income of farmers during harvest season were identified. Result showed there are several seasonal “pitfalls” points in the farmer’s income which made it dropped far below the average value. It has potential to make the farmers not to replant salacca-pondoh then switch to other fruits that are more profitable. Product diversification either vertically or horizontally by allocating some of the fruit and waste to be convert into derivative products can be a step to increase the income of salacca-pondoh’s farmers and intensify the economic activity in Sleman District.
