Species diversity of the genus Theloderma has been extensively studied in recent decades,with the majority of newly described species hailing from the Indochina *** describe a new species of mediumsized Theloderma based on molecular and morphological evidence from lowland forest in the southern part of central java Province,Indonesia,that is highly similar to and considered cryptic within the *** group.A phylogenetic approach shows that this population is a distinct genetic lineage and can be distinguished from its congeners by the absence of vomerine teeth,moderate irregular blunt warts and studded with calcified asperities on the dorsal skin,a distinct color pattern,and a distinct denticle formula in the *** the range of the new species is known only from central java,it cannot be ruled out that it may extends into adjacent areas,such as other parts of java and Sumatra.

Anchovies (Stolephorus sp) is one of the pelagic fish resources which has economic value and abundant in Indonesia waters. The fishing gear to be used to catch Anchovies is the waring purse seine. Demak is one of the fishing base of the waring purse seine in central java. This study aims to analyze the relationship between length-weight, the frequency distribution of anchovy length in Semarang, and Demak waters. This research used an explorative survey method, while the measuring method of fish samples was purposive sampling. Data for Anchovy were obtained in May and October 2018. The correlation between the length-weight of Anchovy in May obtained a value of b=2.759. The longest Anchovy (May) measuring 76.69 mm, weighing 8.8 g, while the shortest size was 34.17 mm, weighing 1.97 g and mode at the mean value of 58.50 mm. The correlation between Anchovy length-weight (October) obtained a value of b =2.126. While the longest Anchovy measures 94.06 mm, weighing of 5.94 g, and the smallest size was 43.68 mm, weighing of 1.44 g while the mode was 65.30 mm in the mean. The catch of Anchovy in October was more feasible to catch than in May.

The development of the industrial sector in Indonesia produces benefits and carries risks, one of which is air pollution. Industrial estates play an important role as economic growth sources with their emissions should have cared about carrying air quality capacity in their area. The projected carrying capacity of air quality is predicted using a simple box model with the emission factor using IPPS. Historical ambient air quality measurements in this area were also collected. Based on the calculation, results show the constructed industries emission load of SO2, NO2, CO, VOC, and TSP 109 tons/year, 128 tons/year, 42 tons/year, 1263 tons/year, and 2008 tons/year. To comply with the ambient air quality standard, the maximum number of industries that can be accommodated in those areas is 190 industries. The critical parameter for violating ambient air quality standard is TSP. Thus, air pollution control strategy should be focused on reducing TSP emission load.

This text aims to conduct a historical analysis of the development of the Semarang-Joana Tram Company or Stoomtram Maatschappij (SJS) in the railway map of Indonesia from the Dutch Colonial era to the Post-Independence period. The analysis employed historical methods, relying on primary sources obtained from Dutch and Indonesian archives and libraries, as well as interviews, site visits, and focus group discussions. The results showed that historical situation factors significantly determined the culture and performance of SJS companies. During the Dutch Colonial period, this situation strongly supported the growth and development of the company due to being assisted by 'an open-door policy' that provided foreign capital. Furthermore, the external factors that benefited the success of the SJS company at the beginning of its development included the following: (1) the ease of processing land for the railway, (2) the establishment of a previously designed railway, (3) the growth of plantation companies, (4) plantations, and (5) urban population improvement. The political changes during the Japanese military occupation led to the integration of SJS management into the government railway management under the Rikuyu Sokkyoku Administration. After Indonesia gained independence, SJS was nationalized and managed under the same administration as the Government Railway Department, which later became PT Kereta Api Indonesia. The shift in management from a private company to a government entity resulted in a decline in SJS performance.

Upland is one of the agroecosystems that has great potential for agricultural business of both food crops, horticulture, and annual crops. Ajibarang is one of the Banyumas' sub district which has approximately 70% of upland area and the rest is rainfed rice field. The success factor of upland rice farming is influenced by the farmer's ability to manage production factors into a profitable business and sustained. This study was aimed to identify the efficiency and its profitability of rice farming business in upland area of Banyumas district. Data were collected using survey method. Simple random sampling technique was done and 51 farmers were selected. Based on the data analysis, we found the average income of farmers was Rp989,817.55/production process with revenue cost ratio is 1.36. The role of community institutions in upland rice farming was very important. Farmers can improve their productivity and increase their income by expanding the cultivation area for upland rice. The rice cultivation in upland area is also suitable for rainfed land.

This study examines Indonesian consumers' willingness to pay for local rice products as against commercial imports. We aimed to determine the consumer preference factors for local rice through a questionnaire survey and experimental auction in Surakarta and Sleman, two areas in the top rice-producing region of central java. The bidding price results of the three rounds of auction to determine the increasing nominal price for the local rice type, after information and tasting sessions, show the participants, as major rice consumers, confirming the highest interest in local rice, while displaying relatively less knowledge of the different rice varieties available in the markets. Most consumers evaluated both cooked and uncooked rice based on swelling and variety. The findings suggest the need to pay greater policy attention to local rice production and varieties, based on the preferences and attributes of the consumers.
