Perubahan Iklim Global juga dirasakan di Indonesia. Berdasarkan data curah hujanantara 1978-2005 telah terjadi kecenderungan penurunan curah hujan denganpeningkatan suhu sebesar 0,04 – 0,047° C/tahun. Karst Wonogiri yang terletak diKabupaten Wonogiri selalu mengalami masalah tahunan berupa kekeringan di musimkemarau. Penelitian ini berjudul Dampak Perubahan Iklim terhadap Neraca Air SecaraMeteorologi dengan Metode Thornthwaite-Mather untuk Analisis Kekritisan Air di KarstWonogiri. Tujuan penelitian ini adalah: 1). mengetahui kondisi curah hujan tahunanselama perubahan iklim di Karst Wonogiri, 2). mengetahui nilai kemampuan menahanair/Water Holding Capacity (WHC) di Karst Wonogiri, dan 3). menganalisis neraca airsecara meteorologis berdasarkan metode Thornthwhite Matter di Karst Wonogiri.Metode analisis imbangan air yang digunakan adalah Thorthwaite Mather untukmenentukan ketersediaan air. Hasil penelitian yang diperoleh adalah: (1) Kondisi curahhujan tahunan di Karst Wonogiri masih termasuk kategori sedang, dengan tebal hujantahunan bisa mencapai 2000 mm. Fluktuasi curah hujan tahunan tidak terlalu tinggi (200-500 mm per tahun); (2) Perhitungan nilai WHC sebesar 112,92 menunjukkan bahwakemampuan lahan di wilayah penelitian untuk menyimpan dan mengikat air termasukrendah yang disebabkan oleh jenis tanah yang ada memiliki solum tanah dangkal hinggasedang serta struktur tanah kersai dan pasiran. Jenis vegetasi penutup yang berupapalawija dengan zone parakaran dangkal juga mempengaruhi besarnya nilai WHC; (3)Analisis neraca air secara meteorologis dapat disimpulkan bahwa ketersediaan air daricurah hujan di wilayah ini termasuk cukup tinggi dengan 7-8 bulan yang surplus. (4)Indeks kekritisan air sebesar 0,56 termasuk dalam kategori mendekati kritisKata kunci: Perubahan iklim, imbangan air
<p><em>Karst is identical with arid, rocky areas and often drought disasters every year. Besides the drought, there are several hazards in the karst area. This study aims to review the various hazards that occur in the Gunungsewu Karst area and mitigation efforts that can be done. Multiple hazards are base on karst hydrological and geomorphological characteristics. This study is base on a literature review in several related studies, both in karst areas and in the research in the same area. Based on the results of the study, it was found that there are four types of hazards found in Gunungsewu Karst areas, namely drought, flooding, pollution, and collapse. In general, mitigation efforts that can be carried out are mapping hazards, monitoring, and increasing the capacity of people in karst areas. However, mitigation efforts are specifically made based on the type of hazards. It was done so that the existing hazards do not pose a disaster risk.</em></p>
<p><em>This study aims to determine the potential of Duwet springs and their availability for supplying fresh water to the surrounding community. we use hydrographs to analyze aquifer characteristics. To analyze the hydrographs, we use water level and spring discharge data. Automatic Water Level Record (AWLR) records water level data for 1 dry season and 1 rainy season every 15 minutes. We use the volumetric method to measure the spring discharge 14 times. We compare the base flow and demand over a year to analyze the potential for fresh water. The results show that the Stage discharge rating curve y = 0.0002e5,453x with R² value of 0.87. Duwet Springs is a perennial spring that has a small discharge (class VI). The largest discharge ever recorded was 0.69 L/s (March 7, 2020) and the smallest recorded was 0.12 L/s (August 21, 2020). BFI value varied between 0.05 and 1 with mean 0.801. The total base flow is 2490675.734 L (rainy season) and 1563419.873 L (dry season). These springs are sufficient for 75% of the rainy season and 84% in the dry season. This indicates that the existence of Duwet springs is very important for the surrounding community.</em></p>
<p><em>The purpose of this study is to find out geography rhythm procurement of raw materials, marketing destination, and problems with production factors sculpture and carving industry in the center of the sculpture and carving industry center in Mulyoharjo Village, Jepara District. This study uses a qualitative descriptive method. The respondent is a sculpture and carving industry entrepreneur in Mulyoharjo Village whose population is 104 industries and 30 industries are sampled. Data collection by interview, documentation and observation. Data analysis used a descriptive qualitative interactive model technique. The results of the study concluded that 86.6% of the industries experienced capital problem,73.3% of the industries experiences raw material problem, 66.6% of the industries experiences marketing problem, and 73,3% of the industries experiences finding workers problem. The most difficult workforce to find is engraver because absence of engraver regeneration. The raw materials used are teak wood and tamarind. In 1990 the raw material came from Jepara. In 1997-2005 the origin of raw materials expanded into the Java Island region. In 2006-2019 the origin of raw materials moved out of Java. The current availability of wood is not experiencing scarcity but the price is increasing. In 1990-1992 the destination areas for product marketing were in the Jepara Regency area only. In 1993-1995 product marketing could reach big cities in Indonesia. Marketing of products to international markets occurred in 1996 until now. In 2013 the number of exports increased with a value of 7,505,772.91 US $. In 2014 to 2018 the number of exports decreased.</em></p>
