Abstract To protect the estuary from sedimentation and waves need a jetty structure. This study discusses the alternative jetty design to be simulated for waves and sediments. The research was located in Batang Regency, Central Java Province. The study objective is to simulate wave and sediment for alternative estuary protection. Preliminary data are collected include topography and bathymetry, tidal observation data that include research area. The secondary data were wind data from BMKG of Semarang Station. The wind data used was each hour data for 16 years in the years 2004 to 2019. To simulate the wave and sediment, a software MIKE was used for the two alternative design. The first alternative using 2 jetties with 100 m length and the second alternative using two jetties with addition length for east side. Based on the sediment transport simulation result, the second alternative design put less 5 cm a year then the first alternative. The evaluation based on cost, time period construction, construction methods, According to the scoring, the first alternative design will be choose to the design and construction step.

Penelitian ini bertujuan untuk mengkaji daya saing komoditi kakao di Sulawesi Tengah dan melihat peran pemerintah dalam meningkatkan daya saing komoditi kakao. Data primer berasal dari observasi, wawancara dan kuesioner, sementara data sekunder berasal dari instansi terkait. Metode analisis menggunakan Policy Analysis Matrix (PAM) dan analisis sensitivitas. Penelitian ini menemukan bahwa nilai PCR Kabupaten Parigi Moutong 0,589 dan Kabupaten Sigi 0,396. Sedangkan nilai DRC Kabupaten Parigi Moutong 0,387 dan Kabupaten Sigi 0,319. Hal tersebut mengindikasikan bahwa usahatani komoditi kakao di Sulawesi Tengah memiliki daya saing, namun tidak menguntungkan secara ekonomi karena Sulawesi Tengah menghasilkan biji kakao yang tidak difermentasi akibatnya petani menerima harga rendah. Berdasarkan hasil analisis, pemerintah belum memberikan proteksi terhadap harga biji kakao dalam negeri melalui harga referensi biji kakao sehingga harga biji kakao didaerah penelitian masih tergolong rendah jika dibandingkan dengan harga di pasar internasional. Sementara terhadap input, pemerintah telah memberikan kebijakan subsidi kepada petani, namun implementasinya masih perlu perbaikan terutama terkait penyaluran dan pengelolaan bantuan agar merata. Kajian ini merekomendasikan masih diperlukan kebijakan pemerintah baik terhadap input maupun output untuk meningkatkan produktivitas, menurunkan biaya produksi dan menaikkan harga jual biji kakao, sehingga dapat meningkatkan daya saing biji kakao. The purpose of this study is to assess the competitiveness of cocoa in Central Sulawesi and to investigate the role of government in improving the competitiveness of cocoa. The primary data were generated through observation, interviews and some questionnaires. The secondary data were obtained from the agency or the institution related to the research. This study uses the Policy Analysis Matrix (PAM) and sensitivity analysis. The study found that the PCR value for Parigi Moutong district was 0.589 and Sigi district was 0.396. While, the DRC value for Parigi Moutong district was 0.387 and Sigi district was 0.319. This indicates that cocoa beans farming in Central Sulawesi has competitiveness, but not economically beneficial because Central Sulawesi produces unfermented cocoa beans consequently farmers receive low prices. Based on the results of the government's impact on output analysis, the government did not provide protection for domestic cocoa seed prices through the reference price of cocoa beans, consequently the price of domestic cocoa beans, particularly in the research area, was relatively low compared to the price of cocoa beans at the international market. Seen from the government policy on inputs, the government have provided subsidies to farmers but they need to improve the distribution and management of aid to be evenly distributed. It is necessary to set up good government policy on inputs and outputs in order to increase cocoa seed productivity, decrease production cost and increase the price which simultaneously can improve its competitiveness in the research location.

Background: Wonogiri Regency is one of the dengue endemic areas in Central Java with a fluctuating number of cases during 2014-2018. The number of dengue cases drastically increased nearly 4 times amounting 52 cases in 2016 to 207 cases in 2017. Weather factors such as rainfall, humidity, temperature, and wind velocity can affect the reproduction and spread of DHF vectors. Objectives: This study was aimed to analyze the association between weather factors (rainfall, humidity, temperature and wind velocity) with the incidence of dengue fever in Wonogiri Regency in 2014-2018. Research Metodes: This research was an analytic observational study using cross sectional approach. The type of data used was secondary data about the weather (rainfall, humidity, temperature and wind velocity) in Wonogiri Regency which was obtained from the Wonogiri Meteorological Station and data on the number of dengue incidents in Wonogiri Regency which were obtained from the Health Office of Central Java Province. The data were used each month for 5 years, from January 2014 to December 2018. Data were analyzed by using univariate and bivariate analysis (Rank Spearman correlation test), because only the humidity variable is normally distributed. Results: The highest number of dengue cases during 2014-2018 as many as 30 cases in November 2018 with an average of 6 cases, the highest rainfall was 887 mm with an average 191.05 mm, the highest humidity was 91.55% with an average of 86.77%, the highest temperature was 28.75oC with an average of 27.50oC and the highest wind velocity was 7.86 knots with an average of 0.89 knots. The results of the Spearman Rank correlation statistical test showed that there was a significant association with moderate strength and a positive direction between rainfall and the incidence of DHF (p = 0.001 and r = 0.420), which means that the increasing of rainfall, the more the number of DHF incidents. There was no significant association between humidity and the incidence of dengue fever (p = 0.925 and r = 0.012). There is a significant association with moderate strength and a negative direction between temperature and the incident of DHF (p = 0.001 and r = -0.415), which means that the increasing the temperature, the number of dengue cases decreases. There is no significant association between wind velocity and the incident of dengue (p = 0.577 and r = -0.073). Conclusion: Rainfall causes the breeding place of Aedes mosquitoes to increase, as a result it has an effect on the increase of the mosquito population. Temperature affects the number of eggs produced by Aedes mosquitoes, so that the density of adult mosquitoes increases.   Keywords: DHF; rainfall; humidity; temperature; wind velocity

Background: Coronaviruses are a family of viruses that can result in different types of illnesses, most commonly, as Severe acute respiratory syndrome (SARS). Researches have shown that the atmospheric variables and the density of population have affected the transmission of the disease. Meteorological variables like temperature, humidity among others have found to affect the rise of pandemic in positive or negative ways.  Respiratory virus illnesses have shown seasonal variability since the time they have been discovered and managed. This study investigated the relationship between the meteorological variables of temperature, humidity and precipitation in the spread of COVID-19 disease in the city of Pune.Methods: This record based descriptive study is conducted after secondary data analysis of number of new cases of COVID-19 per day from the period 01 May to 24 December 2020 in Pune. Meteorological data of maximum (Tmax), minimum (Tmin) and daily average temperature (Tavg), humidity and precipitation were daily noted from Indian meteorological department website. Trend was identified plotting the daily number of clinically diagnosed cases over time period. Pearson’s correlation was used to estimate association between meteorological variables and daily detected fresh cases of COVID-19 disease.  Results: Analysis revealed significant negative correlation (r=-0.3563, p<0.005) between daily detected number of cases and maximum daily temperature. A strong positive correlation was seen between humidity and daily number of cases (r=0.5541, p<0.005).Conclusions: The findings of this study will aid in forecasting epidemics and in preparing for the impact of climate change on the COVID epidemiology through the implementation of public health preventive measures.
