ABSTRAK Air adalah salah satu kebutuhan pokok manusia yang sangat berperan penting dalam kehidupan, air dapat diperoleh dari berbagai sumber, tergantung pada kondisi dan daerah setempat. Penyediaan air bersih untuk masyarakat saat ini menjadi salah satu permasalahan penting, dalam rangka memenuhi kebutuhan air bersih yang semakin meningkat setiap tahunnya. Maka PDAM Unit IKK Anjir Muara Pasar perlu mengkaji kembali kebutuhan air bersih. Metode penelitian yang digunakan yaitu dengan pengumpulan data primer dan data sekunder, kemudian dilakukan perhitungan proyeksi penduduk 10 tahun mendatang menggunakan 3 metode yaitu metode aritmatik, metode geometrik, dan metode least square. Kebutuhan air bersih yang dihitung yaitu kebutuhan domestik, kebutuhan non domestik, dan kehilangan air. Sehingga didapatlah kebutuhan air total 10 tahun mendatang. Hasil perhitungan yaitu kebutuhan air domestik tahun 2028 adalah 37,053 L/dtk, kebutuhan air non domestik tahun 2028 adalah 2,27 L/dtk, kehilangan air tahun 2028 adalah 7,864 L/dtk. Total kebutuhan air tahun 2028 adalah 47,19 L/dtk, kapasitas produksi  tahun 2028 yaitu 47,19 L/dtk. Kapasitas produksi yang terpasang saat ini adalah 70 L/dtk, sehingga pada tahun 2028 kapasitas yang terpasang saat ini memenuhi untuk 10 tahun  ke depan. Abstract Water is one of the basic human needs that plays an important role in life, water can be obtained from various sources, depending on conditions and the local area. The provision of clean water for the community is now one of the important problems, in order to meet the growing need for clean water every year. So the IKK PDAM Unit Promote the Estuary Market needs to review the need for clean water. The research method used is by collecting primary data and secondary data, then calculating the population projection for the next 10 years using 3 methods, namely arithmetic methods, geometric methods, and least square method. The calculated clean water needs are domestic needs, non-domestic needs, and water loss. So that you get the total water needs for the next 10 years. The calculation result is that domestic water demand in 2028 is 37,053 L/sec, non-domestic water needs in 2028 are 2.27 L/sec, water loss in 2028 is 7.864 L/sec. The total water demand in 2028 is 47.19 L/sec, production  capacity in 2028 is 47.19 L/sec. The currently installed production capacity is 70 L/sec, so that in 2028 the installed capacity currently meets for the next 10 years.

This study aims to determine oceanographic characteristics such as tides, waves, and currents in Karimunjawa Coastal Waters during the 1st transitional season and to update the oceanographic database for spatial management evaluation in the region. The tidal characteristics were obtained from the least square method analysis using World Tide software based on Matlab programming language, while wave and current characteristics obtained from 2-dimensional numerical modeling using Mike 21 software on the flow model and spectral wave module. The primary data used were the significant wave height (Hs), wave peak period (Tp), and ocean current components (u and v velocity) on 13-26 May 2016 using the Sontex Argonaut XR type Acoustic Doppler Current Profiler (ADCP) equipment. Tide data were predicted for the Kemujan Islands station from 1-31 March 2020. Secondary data for additional numerical model input were obtained from ERA5-reanalysis in the form of Hs, Tp, u, and v wind velocity data for May 2020 with a temporal resolution of 20 minutes, while bathymetry data derived from GEBCO Satellite Derivated Bathymetry (SDB) data. The tide analysis results showed that Karimunjawa waters are a single daily mixed tidal type. The wave characteristic moves from east to west with high waves reached 0.9 meters and a peak period of 7 seconds. The eastern side of Karimunjawa Island, Kemujan Island, and the western area have a calmer wave. The current characteristic moves northeastward with a speed of 5-28 cm/s, which concludes that in several locations, such as the Menjangan Besar-Menjangan Kecil strait, the currents depend on the tidal conditions.

<p class="1Body">The study is aimed at examining the vulnerability of some residential neighbourhoods in Calabar to the menace of flooding with a view to determining residential areas of high, medium and low flood risk. Two hypotheses were formulated such as: there is no significant relationship between the magnitude of flood, and the vulnerability of residential neighbourhoods and the elements-at-risk to flood in residential neighbourhoods in Calabar do not vary significantly according to the topography of the area. The major primary data were obtained from the metric measurement of the coverage of flood and the assessment of the numerical value of the residential buildings considered vulnerable to flood within the areas measured. Secondary data were also obtained from the collection of both published and unpublished materials and data on flooded buildings and displaced persons were also obtained from the State Emergency Management Agency (SEMA), Calabar. The data were analyzed using descriptive statistics and hypotheses tested using the regression coefficient of the least square method and scatter grams for prediction. The results of the hypotheses were found to be significant as the magnitude of flood determined the vulnerability of some residential neighbourhoods. Vulnerability was found to be higher in low lying residential neighbourhoods. The study, however, recommends among others, planned and autonomous adaptation responses, flood plain zoning to urban agriculture, landscaping and recreational uses. Proper channelization of Calabar urban drainage system, stringent flood control legislation, and development control measures should be enforced so as to discourage people from building on or near flood-prone areas of Calabar.</p>

This study aims to determine the economic value, which is a direct and indirect benefit (tangible and intangible) of Parak in the research area. This research used a case study method, and the sampling was carried out in a purposive manner consisting of 50 sample farmers. The data used in this study are primary data and secondary data. Preliminary data were obtained by direct interviews with respondents based on the questionnaire provided, while secondary data were taken from agencies related to this research. The processing of data obtained in the field shows that Parak plays an important role in supporting the economy of farmers in Nagari Paninggahan either directly or indirectly. The direct use value obtained from the plant is IDR. 46,753,650 (66,316 per cent), from firewood of IDR. 23,070,000 (32,722 percent) and from livestock IDR. 678,550 (0.963 per cent) so that the total direct use income is IDR. 70,502,200 per year of all commodities cultivated by the sample farmers. Meanwhile, for indirect use, such as household/domestic water use, IDR. 13,312,320/year and agricultural irrigation water IDR. 54,052,111/year. The total indirect usage is IDR. 67,364,431,-. Per year. Agroforestry patterns can cover the soil layer well and have an effective influence on soil erosion control to increase the supply of water in the soil. Respondents have also carried out other conservation activities by constructing bench terraces, terracing systems, and other buildings to suppress sedimentation and erosion.

Prime Objective

The dividend is the reward of shareholders of an organization in exchange for time and risk. For maximizing shareholder’s wealth, optimum dividend payout ratio is essential. The prime objective of this paper is to identify impulse of dividend payment decision of listed pharmaceutical companies in Dhaka Stock Exchange of Bangladesh. Dividend payment decision is the dependent variable and profitability, firm’s size, financial leverage, growth, and agency costs are taken as explanatory variables in this study. Collected secondary data are analyzed by econometrics software Eviews 8 through least square method. Formulated multiple regression models show value of R-square (R2) is 0.604817. R-square (R2) value indicates explanatory variables explain 60.48% variation of the dependent variable. The study also reveals that profitability and agency cost positively influence the dividend payment decision and firm’s size, financial leverage, growth negatively impact on the dividend payment decision of selected pharmaceutical companies. Among explanatory variables, profitability is not statistically significant at 5% significant level whereas firm’s size, financial leverage, growth and agency cost are found statistically significant at 5% significant level. So this paper finds that listed pharmaceutical companies in Dhaka Stock Exchange must consider firm’s size, financial leverage, growth and agency cost in their dividend payment decision.
