Mertasari – a village in Kecamatan Purwanegara, western Kabupaten Banjarnegara
Mertasari is a village in Kecamatan Purwanegara, Kabupaten Banjarnegara, Central Java Province, Indonesia. The settlement is located in the central part of Central Java within the Javanese macroregion, with approximate coordinates of 7.45° south latitude and 109.56° east longitude. Kecamatan Purwanegara is situated in the western part of Kabupaten Banjarnegara, approximately 17 kilometers from the regency seat. The subdistrict has an area of 7,387 hectares, a population of 66,695 inhabitants, and is divided into a total of 16 villages. According to data available at the regency level, the topography of Kecamatan Purwanegara is varied: plains stretch across the central and southern sections, while hilly terrain extends through the northern region.
General overview
Mertasari is a relatively small village oriented toward agriculture and fish farming, and it is not among the most frequently visited settlements in Kabupaten Banjarnegara from a tourism perspective. Administratively, it forms part of Kecamatan Purwanegara, and Mertasari is registered as one of the 13 villages in the official administrative records of Jawa Tengah Province. According to data available at the subdistrict level, Mertasari, together with Desa Purwanegara, plays a prominent role in fish farming within the area. A local product characteristic of Mertasari village is a dried banana-based delicacy called Sale Pisang. At the broader subdistrict level, Kecamatan Purwanegara is defined by the presence of a fish market as part of its commercial infrastructure, which was inaugurated on May 18, 2004 by the then-governor of Jawa Tengah, and which is reportedly the largest market of its kind throughout Central Java. Mertasari also entered regency-level public consciousness through a development in November 2025: Desa Mertasari in Kecamatan Purwanegara became the final evaluation site for the expanded scope of the "anti-corruption model village" program on November 18, 2025. The event was a strategic milestone in strengthening integrity culture at the village level, with participation from the Chief Inspector of Kabupaten Banjarnegara and his evaluation team, the subdistrict leader, the village apparatus, members of the village consultative body, BUMDes leaders, and local anti-corruption representatives. This event indicates that the village has made noteworthy efforts regarding local administrative transparency.
Real estate and investment
No independent, settlement-level public data are available regarding the real estate market in Mertasari; the following reflects the broader regency and subdistrict context. Kabupaten Banjarnegara as a whole — of which Kecamatan Purwanegara forms a part, and which is classified as a region with potential in terms of fertile agricultural and fish farming prospects — represents an economy that relies primarily on local agriculture, fish farming, and small-scale commerce sectors. Rural properties in this area generally command lower price levels than those in the agglomerations of larger Central Javanese cities (such as Semarang and Yogyakarta), while investment liquidity is also more limited. According to the general framework of Indonesian land tenure regulations, foreigners cannot acquire direct "Hak Milik" (full ownership) title in Indonesia; rather, "Hak Pakai" (use rights) or leasing arrangements typically remain open to them, with conditions fixed by applicable Indonesian legislation and the prevailing local ordinances. The topographic characteristics of the subdistrict — plains in the south and perbukitan (hilly terrain) in the north — offer different agricultural utilization possibilities, which represents a significant consideration in land valuation. In any case of specific real estate purchase intention, on-site consultation and legal advice are recommended.
Safety and security
No independent, settlement-level crime statistics or other official data regarding public safety in Mertasari are publicly available. The broader region, Kabupaten Banjarnegara, generally presents the profile of an average rural Javanese regency: large-scale crime phenomena characteristic of major cities are not documented for this area. That Mertasari stands in the focus of local administration regarding integrity and transparency is also indicated by the anti-corruption model village program, which aims to make the village a reference point for other villages in developing anti-corruption prevention systems. It may be generally stated that the tight community fabric of small Javanese villages and local governance mechanisms (village councils, BUMDes) contribute to the maintenance of local order; however, data-based statements on this matter can only be made from credible official sources. For travelers, the general precautions applicable in Kabupaten Banjarnegara remain authoritative.
Tourist attractions
No named tourist attraction can be identified within Mertasari village itself; the following presents verified points of interest in Kecamatan Purwanegara and Kabupaten Banjarnegara. At the subdistrict level, the fish farming tradition and local markets — including the Purwanegara market, cited as Central Java's largest fish market, located near the traditional Purwanegara market and SMAN 1 Purwanegara school — offer interested visitors the most authentic local experience. Regarding the broader tourism offerings of the regency, several notable sites are accessible by car from Mertasari. The Waduk Mrica reservoir, which dams the Sungai Serayut, attracts visitors with its scenic panorama. The Sungai Serayu, which flows through Kabupaten Banjarnegara territory, is known as a venue for arung jeram (white-water rafting); one popular route extends from Desa Tunggoro to Desa Singomerto in Kecamatan Sigaluh, spanning approximately 12 kilometers. In the eastern-northern part of the regency, along the shared border with Kabupaten Wonosobo, lies the Dieng Plateau, its Banjarnegara-side portion known as Dieng Kulon. The Dieng Plateau is one of Kabupaten Banjarnegara's most renowned tourist attractions; part of the plateau falls under Banjarnegara administration, while the eastern section belongs to Wonosobo territory. The crater known as Kawah Sikidang is known for its active volcanic activity: hot steam and mud erupt from it, and its name suggests that the position of the crater opening changes from time to time.
Summary
Mertasari is a quiet, rural village in Kecamatan Purwanegara in the western part of Kabupaten Banjarnegara, whose economic foundation is provided by fish farming and agriculture — including the local Sale Pisang product. The village is not among the region's prominent tourism destinations; however, at the administrative level, it merits attention for its participation in the anti-corruption model village program. The broader regency — with its natural characteristics, the Sungai Serayu river, the Waduk Mrica reservoir, and the Dieng Plateau — offers a varied backdrop for those wishing to explore this relatively little-visited rural region of Central Java.
