Abstract

Waste is a very complex and urgent problem to be solved. The problems occur due to the participation of the residents as the leading actor. This study aimed to determine the significance of the influence of gender, age, education, employment status, income, duration of stay, and the level of knowledge on waste generation and management. Respondents to questionnaires and interviews were 37 people whose numbers were determined based on the Slovin equation, while data was analyzed using SPSS Statistics 20 software. A person's educational status significantly positively affects people's habits in reducing waste generation. The following positive significance was income, gender, and length of stay. Age and employment status have a negative correlation, indicating that the older and working, the less waste the society generates. Besides affecting waste generation, it turned out that education also significantly affects waste management. Therefore, education is the main factor considered in waste planning. The results of this study can be used as input for the Indonesian Government in providing information through training and the provision of waste management facilities.

Abstract

Indonesia is an archipelagic country located on the equator. The issue of climate change has become a global issue that has impacted several sectors in Indonesia recently. The presence of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) has contributed to conducting studies on flood and drought events. This review paper summarized 16 published papers that have gone through peer-review, both in the form of publications in journals and at conferences. Since the release of the IPCC AR5 to date, ten studies on flooding and six studies on drought events have been conducted. The most publications on this in 2019 were five publications. Of the various types of the Representative Concentration Pathway (RCP) scenarios used with various methods, the most widely used scenario RCPs is RCP4.5. From the climate change scenario, precipitations parameter is the main parameter that is used in assessing flood or drought events. There are studies conducted on a district / city, provincial scale, and some are even carried out on a watershed scale. The location or province that most flood studies have been carried out is in the capital of Jakarta. The results of these studies generally indicate that the incidence of floods and droughts will increase in the future. Therefore, adaptation steps are needed to deal with unfavorable conditions in the future. Moreover, as the capital city, Jakarta has been estimated that the projected flood incidence will increase. Several publications have provided steps to deal with these challenges on the positive side.

Abstract

Catatan sejarah dan kajian paleo-tsunami membuktikan bahwa siklus tsunami terjadi secara periodik di pesisir Aceh. Kesiapsiapsiagaan masyarakat dapat ditingkatkan dengan rencana tanggap darurat dan respon terhadap peringatan dini. Waktu evakuasi ditentukan oleh perkiraan waktu kedatangan (Estimated Times of Arrival, ETA) tsunami yang menjadi golden time dalam merespon tindakan selanjutnya setelah gempa. Estimasi waktu evakuasi menjadi penentu tingkat keberhasilan saat proses menyelamatkan diri dari kedatangan tsunami. Dengan demikian, tujuan penelitian ini adalah untuk memetakan ketersediaan waktu kritis bagi masyarakat di lokasi-lokasi tinjauan dalam merespon dan melakukan evakuasi setelah gempa terjadi. Pengamatan ETA dilakukan di utara pesisir Aceh, yaitu mencakup Banda Aceh dan Lhoknga juga pulau-pulau terluar sekitar; Pulau Weh, Pulau Nasi, dan Pulau Breuh. Makalah ini melakukan kajian tentang ETA yang dipicu oleh patahan Segmen Aceh-Andaman. Skenario skala gempa ditentukan sebesar 9,15 sebagai rekonstruksi Tsunami 2004 dan 9,2 Mw sebagai kondisi maksimum yang berpotensi terjadi. Pemodelan matematik tsunami dilakukan dengan model Nonlinear Shallow Water Equation (NSWE) dengan diskritisasi numeriknya diselesaikan berdasarkan Metode Beda Hingga skema eksplisit Leap Frog. Proyeksi waktu kedatangan tsunami di titik pengamatan ditentukan dengan fase-fase karakteristik kedatangan gelombangnya. Hasil pemodelan menunjukkan bahwa waktu kedatangan tsunami berdasarkan skenario yang ditentukan berkisar 18-22 menit untuk Sabang, 21-27 menit untuk Pulau Nasi dan Breuh, serta 34 menit untuk Banda Aceh dan Lhoknga. Pemetaan waktu kedatangan tsunami ini memberikan pengetahuan dalam perencanaan dan pengembangan sistem mitigasi tsunami khususnya dari aspek estimasi waktu dalam melakukan evakuasi menuju titik kumpul serta perencanaan jalur evakuasi dan jumlah maupun lokasi pembangunan bangunan evakuasi.Kata Kunci: hidrodinamika pantai, model numerik tsunami, tsunami arrival time, waktu evakuasi, mitigasi tsunami.

Abstract

Nabi Muhammad SAW menggunakan hanya 1 mudd air (sekitar dua pertiga liter) untuk berwudu. Penelitian ini bertujuan untuk mengetahui efisiensi penggunaan air wudu dengan sistem wudu yang berbeda yaitu sistem keran dan sistem kolam, preferensi jemaah Masjid Darul Falah (sistem keran) dan Masjid Haji Keuchik Leumik (sistem kolam) Kota Banda Aceh terhadap sistem wudu. Hasilnya ternyata sistem wudu kolam lebih menghemat air dibandingkan sistem keran, volume wudu rata-rata per individu dengan sistem keran adalah 10,05 l/org dan sistem kolam 3,35 l/org. Dari kedua sistem wudu, mayoritas responden memilih sistem kolam (60%). Diperlukan strategi ke depan agar sistem yang lebih menghemat air bisa lebih dipilih oleh jamaah selain untuk mengikuti tuntunan dalam Islam tapi juga untuk efisiensi penggunaan air.

Abstract

Drainage is one way of removing unwanted excess water in an area and dealing with the effects of excess water in the system. When the rainy season comes, there are almost floods or puddles on urban roads. The large population also makes the volume of drainage channels fill up quickly, while the drainage capacity tends to decrease due to rainwater (erosion) and sedimentation. Meteorological Street, Laut Dendang Village, Percut Sei Tuan sub-district, Deli Serdang Regency, is one of the villages that is frequently flooded every time it rains. On these issues, the researcher highlights the importance of evaluating the Deli Serdang Regency's drainage system along Meteorological Road to anticipate when the rainy season comes. The general exponential method can determine whether the existing drainage volume can still accommodate terrestrial run-off and domestic wastewater in the next 30 years and calculate the population growth. Based on the research results from rainfall data obtained from Meteorology Road, the rainfall intensity value for the last ten years (2010 - 2019) was 10.538 mm/day. Thus, the amount of discharge flowing in the drainage channel (Qplansning) is equal to 0.832 m3/sec, while the planned Q for the next ten years is 0.874 m3/sec, for the next 20 years is 0.953 m3/sec, and 30 years into the future. front is 1.111 m3/sec. Based on the calculation results, Qplans exceeds Qeksisting. Therefore, a new channel plan is needed.

Abstract

Due to the Covid-19 pandemic, the impact of the lockdown on the water quality of major rivers due to restrictions on activities within the country will have an effect. This research compared the Cimalaya Watershed water quality index values before and during the Covid-19 pandemic. River status was conducted using STORET and Pollution Index based on 2019 and 2020 river quality data. Calculations for each method use the same amount of data and parameters, including TSS DO, BOD, COD, TP, Fecal Coliform, and Total Coliform. The results showed a decrease in concentration for water quality parameters in 2020 or during the Covid-19 pandemic compared to 2019. The parameters that experienced a reduction included TSS, DO, BOD, and COD. But besides that, there has been an increase in water quality parameters in 2020, namely the parameters TP, Fecal Coliform, and Total Coliform. The average STORET and Pollution Index values in 2020 indicated that the river is getting moderately polluted than in 2019. This research can be a preliminary study, but using more parameters and methods will make the analysis more comprehensive.

Abstract

Abstract: Indonesia has a very large number of watersheds and has a very diverse size. Damage to several watersheds in Indonesia has also occurred and often results in catastrophic floods and droughts that threaten people. The presence of the RRI Model with its capabilities will help contribute to watershed management in order to solve water resource problems. The RRI model is a two-dimensional (2D) model capable of simulating runoff, rainfall, and flood inundation simultaneously. The use of this model in Indonesia has reached 13 times which was compiled based on the number of publications on the application of the RRI model. All of these publications have passed peer-reviewed papers from both journals and conference papers. Applications have been made in several places including the Solo watershed, the Upper Citarum watershed, the Batanghari watershed, and the upstream Brantas watershed. Given the increasing number of problematic watersheds in Indonesia, the use of this model has the prospect and relevancy of being carried out in other watersheds. However, until now, researchers have had challenges in building hydrological models because of the constraints on the availability of climatological and hydrological data in the watershed. Therefore, in addition to improving the data measuring infrastructure in the field, remote sensing techniques are also needed in an effort to generate targeted watershed information. In fact, the effort to utilize remote sensing in generating unmeasurable data in the field has been successfully conducted in several studies.Abstrak: Indonesia memliki jumlah DAS yang sangat banyak dan memiliki ukuran yang sangat beragam. Kerusakan beberapa DAS di Indonesia juga telah terjadi dan sering berakibat bencana banjir dan kekeringan yang mengancam penduduk setempat. Kehadiran Model RRI dengan kemampuannya akan membantu berkontribusi dalam memajemen DAS ataupun dalam usaha untuk menyelesaikan permasalahan sumberdaya air. Model RRI adalah suatu model dua dimensi (2D) yang memiliki kemampuan untuk mensimulasikan limpasan curah hujan dan genangan banjir secara simultan. Penggunaan model RRI ini di Indonesia telah mencapai 13 kali, yang tercatat berdasarkan jumlah publikasi yang terkait dengan aplikasi model RRI. Semua publikasi tersebut telah melewati peer-review baik dari jurnal maupun dari konferensi. Aplikasi telah dilakukan dibeberapa tempat termasuk DAS Solo, DAS Citarum, DAS Batanghari, dan DAS Brantas. Mengingat jumlah DAS yang bermasalah di Indonesia semakin meningkat, maka penggunaan model ini memiliki prospek untuk dilakukan di DAS lain. Namun sampai saat ini, para peneliti memiliki tantangan dalam membangun permodelan hidrologi karena terkendala pada ketersediaan data klimatologi dan hidrologi di dalam DAS. Oleh karena itu, selain peningkatan infrastruktur pengukur data dilapangan dan teknik pengindraan jauh juga diperlukan dalam usaha menyediakan informasi DAS yang ditargetkan. Usaha penggunaan teknik pengindraan jauh dalam menyediakan data yang tidak terukur dilapangan telah sukses dan terbukti dilakukan di beberapa studi.

Abstract

the Punge Intersection is one of the four-armed unsignalized intersections in Banda Aceh City without traffic regulations such as traffic lights, roundabouts, or other warning signs. This condition is very troublesome for road users, especially during peak hours. It is considered necessary to evaluate the performance of the intersection along with alternative treatments that produce the best performance to meet the standards. Most of the previous studies relied heavily on tailor-made simulation tools to evaluate control algorithms, but the use of simulation platforms to make system comparisons through modeling is still very rare, especially in Indonesia. Analysis and modeling at the Punge Intersection using the MKJI method and PTV VISSIM 10.00-02 (VISSIM) software. Traffic volume data (plan), road geometric, and environmental conditions are needed in data processing operations using VISSIM. Three modeling scenarios were carried out with the implementation of a one-way road for arm A in the entry direction, installation of a traffic signaling tool, called APILL, roundabout planning and widening of each arm. A roundabout planning simulation with type R10-22 with widening on each road section can make the Punge Intersection with the best LOS and meet the best service levels.
