Abstract. Iskandar BS, Iskandar J, Partasasmita R. 2019. Hobby and business on trading birds: Case study in bird market of Sukahaji, Bandung, West Java and Splendid, Malang, East Java (Indonesia). Biodiversitas 20: 1316-1332. Bird species have various ecological and socio-economic-cultural functions for the human being. Ecologically, birds have beneficial functions in the ecosystem, such as helping plant pollinators, spreading plant seeds, participating in controlling agricultural pests, and monitoring environmental changes. Meanwhile, bird functions for the social-economic and culture of the community among them are known as sources of protein food, mystical functions, sources of material stories, sources of inspiration to make songs, craft materials, the source of gene pool, and become pets and trade animals. With the rise of the urban population hobby of raising birds and also the development of various bird contest activities in the urban, causing of the bird trade is very widespread in urban areas, such as in bird markets. In some cities in Indonesia, various bird markets have been popularly known for a long time. This study aimed to elucidate species diversity, folk classification, bird populations, bird prices, constraints to bird trade, and the positive and negative effects of bird trade in the urban bird market. The research method used a mixture of qualitative and quantitative methods with the ethnoecological approach. The results of this study showed that from a survey of 60 bird traders in the bird market of Sukahaji, Bandung, and Splendid, Malang, a total of 160 bird species, representing 38 families were documented. Among them, 10 species representing 7 families recorded as protected bird by law in Indonesia, based on recent government regulation of the Minister of Environment and Forestry of Republic of Indonesian No.106/MENLHK/SETJEN/KUM.1/12/2018. A total of 2,950 individuals were recorded in Sukahaji; while in Splendid were recorded 3,558 individuals. Prices of birds that are traded varied greatly depending on the species and characteristics of birds. It has been revealed that bird trade in the bird market has been various economic benefits for many people. However, due to the bird trade in bird markets in the city which has not been properly managed, the sustainability system of the bird trade in the city is very alarming caused of many factors, including decreasing of bird population over time in rural ecosystem as main supply of urban bird trading in the bird markets. Therefore, bird trading in the bird markets must be properly managed based on the sustainable development program concept, namely pro-economic, pro-social, and pro-environment.

Bridgeheader is one of the typology of low-income people in the city who assume that the house is only ‘a springboard’ for their life in the city. This group of people dwelt not far from the location of their place to work; occupying marginal spaces in the city and its environment tend to be slump. Almost all areas in the city of Jakarta have marginal spaces, therefore the government attempt to improve the quality of their houses, for example by providing low-cost housing. In fact the low-cost house which was provided by the government failed to be ‘consumed’ by the brigdeheaders at the time when the used value of the house has been turned into market value. The research aimed to determine such approaches of use value of the house that can be ‘consumed’ by the brigdeheader, but did not undermine the space in the city. Data collection methods using practical observation conducted with interviews. While the analysis using descriptive pragmatic method in four case study area in Jakarta. The findings indicate that the concept of house for this group is not determined only by the ‘low price tag’ but also ‘the way of use’ of the space contributed with the result that the house can be ‘consumed’ well.

Bangun Kreasi Abadi is one of the distributors working with PT. Jui Shin Indonesia in marketing and distributing Garuda cement products to several regions in West Java, especially the city of Bandung. In the distribution process, CV Bangun Kreasi Abadi does not send its cement products directly to consumers, but CV. Bangun Kreasi Abadi uses two warehouses as transit points for the delivery of cement products for several regions. The transshipment method has several problems because in the distribution process, products are not sent directly to consumers but must pass through several transit points first. This will result in large costs because the delivery process will be twice as long and will also result in a longer lead time. This study aims to determine the optimal allocation of Garuda cement distribution to produce minimum transportation costs from distributors to warehouses and from warehouses to service points (retailers) using the Transshipment method with the help of Lingo Solver Software. The result of transportation costs from distributors to warehouses is Rp. 25,655,900 and transportation costs from warehouses to retailers of Rp. 26,140,220, the total cost of Garuda cement distribution is Rp. 51,796,120.

Crystal guava is one of guava variety which currently has the high opportunity and potential to be developed in Indonesia. Waaida Farm as a company engaged in crystal guava farming in Sumedang District can only meet 5,71% of its demand every year. Therefore, Waaida Farm needs to expand the cultivation area to optimize the crystal guava potential. The expansion constrained by financial source. Crystal guava farming in Waaida Farm is not bankable yet eventhough the business itself has run for six years. The objective of this research is to analyze financial feasibility of crystal guava farming at Waaida Farm. The research was conducted using qualitative descriptive design and case study technique. The data collection methods used were observation, interview and literature study. From the financial aspect, crystal guava farming at Waaida Farm is feasible to be implemented, based on the calculation results of investment criteria using interest rate of 18,75%. The calculation results of NPV is positive which is Rp 5.982.165, IRR is over the established interest rate which is 28,43%, Net B/C is greater than 1 which is 1,59, and payback period is 5 years, shorter than the project term analysis which is 10 years. The sensitivity analysis showed that the variable of the decreasing of production number is more sensitive than the variable of the increasing of production cost. Nevertheless, the 10 percents change of every variable still make the crystal guava farming feasible to be implemented.Keywords: Crystal Guava, Financial Feasibility

Abstract At present, concentrations of pharmaceuticals in surface and ground waters are low; however, even low concentrations of certain substances may prove very harmful. One of such pharmaceutical drugs is diclofenac, a popular non-steroidal anti-inflammatory drug (NSAID). For this reason, it is important to determine its mobility in groundwater and to estimate parameters of migration. Authors conducted column tests for two porous media: an artificial one, consisting of glass granules, and a natural one, i.e., sandur sand obtained from a site north of the city of Poznań (Poland). During the test, impulse breakthrough curves of chloride ions and diclofenac were recorded. The results were used to identify a specific sorption model and to determine values of migration parameters. Solutions of the inverse problem using optimisation methods and of equations of mathematical migration models were carried out in a MATLAB environment. Based on test results, the mobility of diclofenac is shown to be very high and comparable to that of chloride ions. The tests also revealed a slight and irreversible sorption of diclofenac on grains of both porous media.
