Abstract The dynamics of air temperature cause thermal comfort to be unstable in the context of an urban micro-climate. One of the places affected by the urban micro-climate is the campus of Unissula. It lies on the main transportation route of the north coast of Central Java. To create a comfortable space in the campus environment, a local scale air temperature control method is required, one of which is the provision of green open spaces (GOS). Scenarios for providing green open space based on micro-climate dynamics must be developed to create thermal comfort. This study aimed to identify and analyze the correlation between micro-climate and thermal comfort based on the existing parameters. The research methodology employed a rationalistic quantitative deductive approach with micro-climate and thermal comfort variables, as well as rationalistic descriptive analysis technique. According to the findings of this study, the comfort of Unissula campus meets the criteria for morning air temperature of 25.42°C, daytime 31.35 °C, evening 29.92 °C. The morning humidity is relatively 73.92%, the daytime is 51.50%, and the evening is 60.57%. The thermal comfort level is moderately partly comfortable.

Abstrak. Jejak awal Pengaruh Hindu-Buddha di Sepanjang Pantai Utara Jawa Tengah: Survei Arkeologi di Kota Batang. Penelitian arkeologi di pantai utara Jawa Tengah mengenai kehidupanmasa Hindu-Buddha hampir selalu dipusatkan pada wilayah antara Kedu-Yogyakarta, yang dikuasaioleh Kerajaan Matāram pada sekitar abad ke-8–9 Masehi. Penelitian yang berupaya mempelajaridan merekonstruksi kondisi sosial masyarakat di daerah pesisir masa pra-Matāram selama ini belumpernah dilakukan. Karya tulis ini berusaha melakukan eksplorasi pada masa pra-Matāram di JawaTengah, khususnya di Kabupaten Batang yang diduga sebagai salah satu daerah yang penting padaawal periode sebelum munculnya Kerajaan Matāram di pedalaman Jawa Tengah. Pengumpulan datadilakukan melalui survei, selanjutnya data arkeologi yang relevan dilakukan analisis deksriptif untukmenjawab pertanyaan di dalam penelitian. Hasil survei berhasil mengidentifikasikan sejumlah temuanpenting seperti arca, candi dan prasasti mulai dari wilayah pesisir sampai pedalamanan KabupatenBatang. Berdasarkan identifikasi sejumlah temuan arkeologi tersebut tampak bahwa wilayah Batangsudah mendapat pengaruh Hindu-Buddha jauh sebelum munculnya Kerajaan Matāram kuna sekitarabad ke-8 M. Abstract In Coastal Central Java, archaeological research dealing with the Hindu-Buddhist periodis almost always focused on the coastal area between Kedu and Yogyakarta, which was controlledby the Matāram Kingdom around the 8-9th Century AD. Research that attempts to investigate andreconstruct the social conditions of coastal communities during the pre-Matāram period has yetto be undertaken. This paper is such an attempt. It explores Hindu-Buddhist remains in the BatangDistrict, a district which, we believe, was an important entry point for Hindu-Buddhist traditionsprior to the emergence of the Matāram Kingdom in the hinterland of Central Java. Data collectedthrough the survey, further archaeological data relevant will be conducted descriptive analysis toanswer questions in the study. The survey results have identified a number of important findingssuch as statues, temples and inscriptions ranging from coastal areas to inland Batang. Based onthe identification of a number of archaeological findings it apparent that the area in Batang alreadyappear influence of Hindu-Buddhist long before the emergence of the ancient Matāram Kingdomaround the 8th Century AD.

The City

By the beginning of the twentieth century, Semarang was a major port city and administrative centre on Java. Attainment of this position was due partly to the expansion of its hinterland during the nineteenth century. This expansion was closely related to developments in the means of transportation and the consequent ability of plantation owners to bring the products of their plantations to the port for shipment to foreign markets. By the end of the century virtually the whole economic life of central Java focused upon Semarang. The city also exercised administrative functions in the Dutch colonial administration and generally had been responsible for Dutch interests in the middle and eastern parts of the island. The importance of Semarang as an administrative centre increased after 1906. In that year the government incorporated the city as an urban municipality (stadsgemeente). In 1914 it had consular representation from the United States, Belgium, Denmark, France, Great Britain, Italy, Norway, Germany, and Thailand. Subsequently, in 1926 it became the capital of the Province of Central Java under the terms of an administrative reform fostered by the colonial government at Batavia. Status as an urban municipality meant that local officials sitting on a city council would govern the domestic affairs of the city. The members of the city council at first were appointed from Batavia, subsequently some of them were elected by residents of the city. By the beginning of the twentieth century Semarang had enhanced its position as a major port on the north coast of the island of Java. It was one of the foremost cities of the Dutch East Indies, along with Batavia and Surabaya, a leading port and a centre of administration and trade. This article outlines the growth of the port of Semarang during the nineteenth century and discusses some of the conflict related to this growth over living conditions in parts of the city during the twentieth century, a conflict which smouldered for several decades among the government, members of the city council, and the non-European residents of the city, one which remained unresolved at the end of the colonial era.

Coastal Changes

Severe abrasion occurred in the coastal area of Brebes Regency, Central Java between 1985 and 1995. Since 1997, mangroves have been planted around the location as a measure intended to prevent further abrasion. Between 1996 and 2018, monitoring has been carried out to assess coastal change in the area and the growth and development of the mangroves. This study aims to monitor mangrove growth and its impact on coastal area changes on the north coast of Brebes, Central Java Province using Landsat series data, which has previously proven suitable for wetland studies including mangrove growth and change. Monitoring of mangrove growth was analysed using the normalised difference vegetation index (NDVI) and the green normalised difference vegetation index (GNDVI) of the Landsat data, while the coastal change was analysed based on the overlaying of shoreline maps. Visual field observations of WorldView 2 images were conducted to validate the NDVI and GNDVI results. It was identified from these data that the mangroves had developed well during the monitoring period. The NDVI results showed that the total mangrove area increased between 1996 and 2018 about 9.82 km2, while the GNDVI showed an increase of 3.20 km2. Analysis of coastal changes showed that the accretion area about 9.17 km2 from 1996 to 2018, while the abrasion being dominant to the west of the Pemali River delta about 4.81 km2. It is expected that the results of this study could be used by government and local communities in taking further preventative actions and for sustainable development planning for coastal areas.

Indonesia reported a maximum annual temperature rise of 0.3°C in urban regions. Semarang, the largest metropolitan city in the province of Central Java, is also experiencing an increase in temperature due to climate change therefore activities in urban public spaces are disrupted due to the absence of a comfortable temperature. Urban design elements, including land cover materials, road geometry, vegetation and traffic frequency expressed significant effects on micro-climate. Measurement of Thermal Comfort in Urban Public Spaces Semarang was carried out s at the micro level as an old historical district The Old Town and Chinatown. This increment indeed influences thermal comfort level in its outdoor environments which are important for comfortability of outdoor activity. This study aims to analyse surface temperature through Thermal Comfort Measurement. Data was obtained by measuring air temperature, wind speed and humidity in the morning, afternoon, and evening. Inverse distance weighted (IDW), thermal comfort calculations and micro-climate model were employed to evaluate existing physical conditions of these settlements. The results showed both Old Town and Chinatown observed thermal comfort value above 27°C and are categorized as uncomfortable for outdoor activities. This research is contributing to the need to further develop public spaces to potentially adapt to environmental changes.

Trawl Catches

Demak is a coastal area on the North Coast of Java with a large enough potential for demersal fish resources. This research aimed to determine the composition, the length and weight distribution, and catch per unit effort (CPUE) of demersal fish caught using mini bottom trawl at the north coast of Demak Regency. The research was carried out in October-December 2020 by observation of ten trips of mini bottom trawl fishing. Each fish captured was then grouped by type, identified, and measured its length and weight. The result showed that 38 species consist of 31 fishes, four mollusks, and three crustaceans. The fish captured dominated by pony fish (Leiognathus equulus) as much as 31.23% and largehead hairtail (Trichiurus lepturus) of 23.52%. The catch per unit effort (CPUE) average of mini bottom trawl was 44.77 kg/trip. Mainly fish (more than 95%) caught in small size compared it’s the maximum attainable length (L-max), with all the weight ranges from 0.3 to 520 g and more than 98% sized 0.3-80 g. Mini bottom trawl catches many types of fish and small size; therefore, mini bottom trawl is classified as a type of fishing gear with a very low selectivity level.
