Jakarta Bay is a bay that has an important role in Jakarta, but the activity in this area lead to the potential for pollution mainly ammonium and nitrate. Pollution peaks generally occur during the rainy season (west monsoon). Pollution that enters the bay can be neutralized naturally by water as long as the amount does not exceed the asimilation capacity. This study aims to calculate the total input (load), assimilation capacity, and residence time of ammonium and nitrate in Jakarta Bay in the rainy season. Data from this study is derived from secondary data. For the total input of pollutants are calculated from the input stream, the atmosphere and the boundary. From the research found that the Jakarta Bay had a total load of pollutants NH4 at 115.8 x 109 mmol N /month and NO3 46.5 x 109 mmol N/month. The biggest contributor to the pollution comes from the boundary NH4 is 56.9% and NO3 from the river 70.1%. Load from Citarum river for NH4 around 3.8 x 1010 mmol N/month and NO3 around 3.0 x 1010 mmol N/month higher than Marunda, Priok and Angke the rivers. Assimilation capacity of Jakarta bay  for NH4 around 25.7 x 109 mmol N /month and NO3 of 24.1 x 109 mmol N /month. It shows the total load of pollutants entering the Jakarta Bay is greater than the assimilation capacity. The residence time of water in the Bay of Jakarta is 13.3 days longer than the residence time of NH4 and NO3 which were only 8.6 and 9.2 days.

Mastigias papua is a jellyfish that is trademark of marine lakes. Ongeim’l Tketau Lake in Palau, Hang Du I Lake in Vietnam, Kakaban Lake in Kalimantan, and Lenmakana Lake in Raja Ampat Papua are exotic tourist destinations because of presence of these biota in the lake. Water temperature is very influential on the life of a jellyfish because of its mutual symbiosis with brown algae zooxanthellae. Mastigias has totally disappeared in several places due to water temperature increasing, including Lenmakana Lake in the West Monsoon 2017/2018 and 2018/2019. The absence of Mastigias in this lake will be explained by recorded logger data installed in the lake and at sea. Secondary data from NOAA and BMKG will be used to explain the condition of absence of jellyfish. Water lake temperature data showed an increase to 2.5oC when the Mastigias disappeared. Temperature increasing occur due to seasonal cycle patterns of lake water temperatures and weather cycles which change in time, the dry season occurs faster and the rainy season occurs slower. Conversely, in the West Monsoon 2019/2020, Mastigias still found in the lake. The rainy season which is 20 days faster than normal condition helps reduce the heat in West Monsoon.

Spatial And Temporal Characteristics

This study aims to analyze spatial and temporal variation of rainfall in the year 1971 until the year 2007 that is divided into two (2) periods ie 1971-1989 and 1990-2007 in relat ion to climate global change. The research was conducted in the area of East Java province from July until December 2008. The secondary data used in the research were: 1) Rainfall monthly data from 106 stations located in East Java within the period of 1971-2007 obtained from the Agency for Meteorology and Geophysical Karangploso Malang, 2) Sea Surface Temperature Nino 3.4 (http ://www.cpc.ncep.noaa.gov.), 3) Soil map scale 1: 250,000 obtanined from the Center Institute for Environmental Resource Management of Agriculture, and the map of Agroecological Zone (AEZ) of East Java scale 1: 250,000 from Assessment Institute for Agricultural Technology East Java. The analysis of rainfall characteristic consists of a) the changes of climate type Oldeman, b) the changes of the early dry and rainy season, c) the changes in of rainfall amount in dry and rainy season. The results showed that in 1971-1989 periods, the type of Oldeman climate in East Java vary from B1 to E, but after the 1990s the type of Oldeman climate change varied from C1 to D4 meaning that a part of East Java area (16.7%) become drier and 17.8% area of East Java became wet. The analysis of rainfall stations (106 stations) showed that some of rainfall stations (58.49%) have decreased the number of dry season rainfall about 3 - 500 mm/season. 56 stations (52.8%) have increased the number of rainy season rainfall in the range 1-600 mm /rainy season, while the 49 rainfall stations (46.22%) have decreased the number of rainfall in the range of 1-500 mm/season. Changes in the characteristics of rainfall in East Java, which occurred within the period of 1971-1989 and 1990-2007 was caused by the ENSO phenomenon.

The aims of the study were to quantify nutrient loads from point and diffuse pollution sources in the Rio Mannu stream and to simulate mitigation measures for reducing nutrient loads delivered to the Santa Gilla wetland. The Soil and Water Assessment Tool model was used for simulating hydrology, nutrient balance and water quality. At the basin scale, the input from fertilisers was 80.3 kg ha−1 year−1 total nitrogen (TN) (87.6% of the total input) and 27.6 kg ha−1 year−1 of total phosphorus (TP) (99.8% of the total input). Atmospheric deposition and biological N-fixation together accounted for about 12% of the total TN input. The TN and TP from wastewater treatment plants (WWTPs) were about 14.2 t year−1 and 3.1 t year−1, respectively. Nutrient loads delivered to the river system differed among the sub-basins, with TP ranging from 0.2 kg ha−1 year−1 to 2.7 kg ha−1 year−1, and the sum of organic N and NO3-N ranging from 1.8 kg ha−1 year−1 to 22.9 kg ha−1 year−1. Under high flow conditions, NO3-N and TP accounted for 89% and 99% of the total load, respectively. The low flow contribution to the total load was very low, with NO3-N and TP accounting for 2.8% and 0.7%, respectively. However, the natural hydrological regime in the study area is intermittent, and low flow represents a critical condition for the water quality due to the high concentrations of TP and NO3-N from WWTP discharge. To improve the water quality, the reuse of treated wastewater from three WWTPs for irrigation purposes on olive cultivation, coupled with a 20% reduction in fertiliser application, was simulated. The results showed a reduction in nutrient loads at the outlet for all hydrological conditions. However, additional measures are needed for improving water quality.

Pesawaran District, Lampung Province, is a high malaria-endemic area. Environmental factors, such as rainfall in the rainy season and dry season have an effect on malaria cases. The increase in malaria cases and the causes of infection are thought to be related to the changing seasons. The purpose of the study was to determine the comparison of malaria cases based on the seasons in the endemic areas of the Hanura Health Center Pesawaran District. This research is descriptive, with total sampling taken in the form of secondary data per malaria case and Plasmodium species in Hanura Health Center in 2016-2017. Determination of the rainy season and the dry season is based on the average rainfall data obtained at BMKG Lampung Pesawaran Climatology Station in 2018. Univariate analysis was carried out to determine the frequency distribution of malaria cases and Plasmodium species based on the season, and Independent T-test to compare malaria cases in the rainy and dry season. In total there were 4266 malaria cases consisting of malaria cases in the rainy season as many as 2486 cases with falciparum malaria as many as 1414 cases and malaria cases during the dry season as many as 1780 cases with falciparum malaria as many as 899 cases. The results showed significant differences in malaria cases during the rainy season and dry season with a P-value of 0.046. High rainfall (> 50mm) during the rainy season allows an increase in the volume of water from upstream to sea resulting in rivers, ponds, and sewers becoming habitats potential for the breeding of Anopheles spp. Abstrak Kabupaten Pesawaran Provinsi Lampung merupakan daerah endemis tinggi malaria yang mengalami perubahan musim setiap tahunnya. Faktor lingkungan seperti curah hujan pada musim hujan dan musim kemarau berpengaruh pada kasus malaria. Peningkatan kasus malaria dan penyebab infeksinya diduga terkait dengan perubahan musim yang terjadi.Tujuan penelitian ini untuk mengetahui perbandingan kasus malaria berdasarkan musim di daerah endemis wilayah kerja Puskesmas Hanura Kabupaten Pesawaran. Jenis penelitian adalah deskriptif, dengan pengambilan sampel secara total sampling berupa data sekunder per bulan kasus malaria dan spesies Plasmodium di Puskesmas Hanura pada tahun 2016-2017. Penentuan musim hujan dan musim kemarau berdasarkan data rata- rata curah hujan yang didapatkan di BMKG Stasiun Klimatologi Pesawaran Lampung tahun 2018. Analisis univariat dilakukan untuk mengetahui distribusi frekuensi kasus malaria dan spesies Plasmodium berdasarkan musim, dan uji T-test Independent untuk membandingkan kasus malaria pada musim hujan dan kemarau. Total sampel terdapat 4266 kasus malaria yang terdiri dari kasus malaria pada musim hujan sebanyak 2486 kasus dengan malaria falsiparum sebanyak 1414 kasus dan kasus malaria pada musim kemarau sebanyak 1780 kasus dengan malaria falsiparum sebanyak 899 kasus. Hasil penelitian menunjukkan perbedaan yang bermakna pada kasus malaria pada musim hujan dan musim kemarau dengan nilai P=0,046. Curah hujan yang tinggi (>50mm) pada musim hujan memungkinkan adanya peningkatan volume air dari hulu ke laut yang mengakibatkan sungai, kolam, tambak dan selokan menjadi  habitat potensial berkembangbiaknya vektor malaria nyamuk Anopeles spp.

ABSTRAK Berlebihnya ketersediaan air irigasi yang disebabkan oleh debit air yang melimpahpada saat musim hujan dan sifatnya tidak merata, dimana pada bagian hulu ketersediaan air cenderung berlebih dan di hilir cenderung kekurangan. Dengan adanya kondisi seperti itu maka perlu dilakukan penelitian mengenai kelebihan air irigasi pada saat musim hujan agar dapat dilakukan pengelolaan air secara proporsional pada (DAS) Ho. Penelitian dilakukan untuk mengetahui persentase kelebihan air irigasi yang ada pada setiap subak dan menentukan teknik pengelolaan air irigasi agar proporsional pada setiap bagian subak. Perolehan data primer dilakukan dengan metode wawancara, pengamatan, dan pengukuran sedangkan data sekunder diperoleh dari (BMKG) Wilayah III Denpasar. Data yang diperoleh selanjutnya dianalisis dengan CROPWAT 8.0 untuk mencari persentase kelebihan air irigasi yang terjadi pada saat musim hujan dan untuk menentukan proposi distribusi air irigasi. Hasil penelitian menunjukan persentase kelebihan air irigasi pada subak (DAS) Ho saat musim hujan rata-rata pada daerah hulu 207,31%, tengah 417,78%, hilir 239,05%. Teknik pengelolaan distribusi air pada hulu, tengah, hilir saat musim hujan agar kelebihan bersifat proporsional yaitu dengan cara mengubah debit awal sesuai dengan debit rekayasa.  ABSTRACT The excess of water availability is caused by excessive water discharge during the rainy season, and it doesn’t distribute evenly between upstream and downstream, where upstream water availability tends to be oversupply and downstream is deficient. With such conditions, research is needed on excess irrigation water during the rainy season in order to perform an optimal water management in Ho Watershed. Research was conducted to determine the percentage of excess irrigation water available in each subak and determine irrigation water management techniques to be proportionate to each subak section. The acquisition of primary data is done by interview, observation, and measurement methods, while secondary data is obtained from (BMKG) Region III Denpasar. The data obtained was further analyzed with CROPWAT 8.0 to find the percentage of excess irrigation water that occurs during the rainy season and to determine the distribution portion of irrigation water. The results showed the percentage of excess irrigation water in the Ho watershed during the rainy season averaged 207,31%, middle 417,78%, downstream 239,05%. Water distribution management techniques in the upstream, middle, downstream during the rainy season so that the excess is proportional by changing the initial discharge in accordance with the approximation discharge.

Nusa Penida is a tourist destination, located on the east of Bali, which is well-known of its natural panoramic. Increasing tourism sector in Nusa Penida may have positive impacts, but it can also have negative impacts, such as an increase in the amount of waste and other pollutants, which will eventually be discharged into the waters. High concentration of pollutant can reduce water quality. The water quality in the sea can be control by the residence time, and the sea current would spread waste in the ocean. Based on these problems, it is important to conduct a research on the movement and length of particle residence in the waters of Nusa Penida, Bali. This research was carried out in January 2019, to represent the rainy season conditions, and in July 2019, to represent the dry season conditions. The residence time was calculated  using a numerical modeling method namely Finite Volume Coastal Ocean Model (FVCOM). Based on the simulation results, the residence time of particle in the dry and rainy season has a similar pattern. Areas with fast residence times are found in the eastern Nusa Penida waters, while areas with weak residence times are found in the Toyapakeh strait. Generally, Nusa Penida waters have a relatively short residence time, 1- 4 hours.

PT CRB is a taxpayer who has a business in the field of medical health services specifically eye hospital. Initially, PT CRB only reported its monthly Value Added Tax (VAT) from January to December 2019. However, the reported amount of Input Tax wasn’t in accordance. Input Taxes from drug purchases can’t be separated exactly between delivery of drugs that are VAT payable and non-VAT payable, so the Input Taxes can’t be fully credited and must be calculated with the guidelines of the Minister of Finance Regulation No. 135/PMK.11/2014. The purpose of this research was to determine the calculation of PT CRB Input Tax in 2019, the results of the recalculation of Input Taxes in accordance with PMK 135/PMK.11/2014, and the analysis of recalculated Input Taxes impact. The types of data used in this research are qualitative and quantitative data with secondary data sources. Data collection in this research is using interview techniques and documentation techniques. The data analysis technique used in this research is quantitative descriptive data analysis. Based on the results of the research, it can be concluded that the calculation of Input Tax on hospital services before recalculation shows that the total Input Tax reported by PT CRB in 2019 is about Rp. 180,518,250 and it has been fully credited. Results of the recalculation of Input Tax on hospital services at PT CRB 2019 based on PMK 135/PMK.11/2014 is Input Tax that can be credited during the January to December 2019 tax period is only Rp 63,914,935. The results of recalculated Input Taxes impact analysis are in the form of underpaid VAT of Rp 116,603,315 that be the main impact and the impact of administrative sanctions in the form of interest of 2% due to late payment of taxes.

Observation Results

Cases of dengue hemorrhagic fever are associated with the potential for rainfall, temperature, and humidity. In a month mosquitoes can lay eggs approximately four times. In a month mosquitoes can lay eggs between 400 to 600 eggs. Mosquito eggs can survive, do not hatch, for six months because they do not touch the water. The existence of rainfall, humidity, and the appropriate temperature can accelerate the process of hatching mosquito eggs. Secondary data analysis research methods on BMKG data and Makassar City Health Department data in 2014, 2015, 2016, 2017 and 2018. The data analysis was carried out on 1–8 October 2019. The observation results revealed that high rainfall occurred in January, February, March, April, May and June. In July, August, September the rainfall is very low. Then entering November and December, the rainfall starts to high again. Air temperature does not occur significantly or not too extreme a difference every month. Humidity in the rainy season tends to be high. The incidence of dengue fever in the rainy season tends to increase. The number of mosquito larvae also tends to increase in the rainy season. It is recommended that before entering the rainy season, it should increase awareness of the incidence of dengue fever by reducing mosquito breeding sites through draining, closing, stockpiling. Drain and close the bathtub, and bury cans, plastic, and objects that can become mosquito breeding grounds.
