Abstract

Banjir di Daerah Aliran Sungai (DAS) Mempawah masih menjadi bencana lingkungan yang sampai kini belum teratasi. Hal ini diantaranya disebabkan oleh belum tersedianya informasi spasial kerawanan banjir di wilayah tersebut yang mengacu pada kondisi DAS sebagai dasar untuk menentukan prioritas strategi dalam mitigasi banjir dan perencanaan pengelolaan dan pemanfaatan DAS yang berkelanjutan. Tujuan penelitian ini adalah memetakan kerawanan banjir di DAS Mempawah khususnya di wilayah Kabupaten Mempawah dan Kabupaten Landak dengan menggunakan analisis spasial berbasis Sistem Informasi Geografis (SIG) dengan overlay, scoring, dan weighting. Parameter penelitian terdiri atas curah hujan, elevasi lahan, kemiringan lereng, tipe tanah, tutupan/penggunaan lahan dan kerapatan jaringan sungai. Hasil penelitian menunjukkan bahwa tingkat kerawanan banjir DAS Mempawah pada Kabupaten Mempawah termasuk pada klasifikasi tidak rawan hingga kerawanan tinggi, sedangkan tingkat kerawanan banjir pada DAS Mempawah di Kabupaten Landak termasuk ke dalam klasifikasi kerawanan rendah hingga kerawanan tinggi. Kejadian banjir di DAS Mempawah ini dipengaruhi oleh faktor curah hujan, topografi yang landai, penurunan kapasitas jaringan sungai, dan penggunaan lahan. Pengelolaan DAS Mempawah dapat dilakukan diantaranya dengan (1) menjaga debit limpasan air melalui pemanfaatan daerah rawa sebagai tempat parkir debit limpasan air dan menjaga hutan atau melakukan penghijauan; (2) melakukan kegiatan penanganan dan perawatan sungai di DAS Mempawah untuk menjaga kapasitas sungai; (3) menyusun pengaturan penggunaan lahan yang menyesuaikan dengan adanya risiko rawan banjir; dan (4) pengelolaan DAS terpadu.

Abstract

Background: The main nutritional problem concerned by the Indonesian government is the stunting. This condition is affected by various aspects, mainly caused by infectious diseases, clean and unharmonious living behavior, the availability of drinking water, and environmental sanitation. Objectives: The purpose of this study is to determine the relation of infectious diseases, water access, hygiene practices, and sanitation towards the stunting incidence factors in Sambas Regency. Methods: This research used Ex Post Facto with a case-control design. The study population was residents of Sambas Regency with a total of 535,725 people, a total sample of 241 children aged 0-59 months comprising of 89 respondents as cases and the rest 159 respondents as controls, using inclusion and exclusion criteria both from the control group and from the case group. Data analysis used the chi-square test. Results: The results showed a relation of infectious diseases (p-value=0.000), drinking water sources (p-value=0.000), clean and healthy living behavior (p-value=0.000), and environmental conditions (p-value=0.000) with the stunting incidences. Conclusions: The study concludes that there is a significant relation of infectious disease variables, the drinking water sources, hygiene practices, and environmental conditions with the stunting. It requires control and completion of the stunting cases through environmental sanitation improvement, namely the provision of access to clean water, healthy and clean living behaviors, and good cooperation between the government and the community, in educating people through counseling and socialization of the stunting prevention and management.

Abstract

Penelitian dilakukan untuk mendapatkan model aliran air tanah pada lahan gambut yang dipengaruhi oleh pasang surut. Pemodelan aliran air ini diharapkan dapat mendukung pengembangan pertanian dan perkebunan pada lahan gambut. Pengaturan tinggi muka air tanah pada lahan gambut secara tepat dapat membantu system pertanian dan menghindari kerugian pada tanaman. Penelitian ini dilakukan melalui eksperimen pada lahan gambut dengan membuat 13 titik pengamatan pada lahan dan 4 titik pengamatan pada saluran. Model aliran air pada lahan dibangun dengan menggunakan persamaan Kirkham yang telah dimodifikasi. Model yang diperoleh menunjukkan hasil yang dapat mewakili kondisi aliran air pada lahan dengan memberikan galat baku pendugaan terkecil sebesar 0% pada titik pengamatan-9. Model juga menunjukkan bahwa tinggi muka air di saluran tersier merupakan parameter utama dalam pengendalian muka air tanah di petak lahan.Kata kunci :Pemodelan, aliran air tanah, persamaan Kirkham, tinggi muka air tanah, tanah gambut

Abstract

Pontianak city is the capital of West Kalimantan Province, undergoing dynamic growth and development in various sectors. However, it is often hit by inundation or flooding, affecting region development, particularly economic structure. The effort that can be made is the Low Impact Development (LID) Approach to overcome flooding and inundation in urban areas while providing economic value benefits. This research analyzed the economic structure of Pontianak City with an analysis of LQ, Typology Klassen and Shifted Share to look at the growth of the base sector and the movement of economic structures. AHP analysis is used to look at the perspective of LID application in Pontianak City. The results showed that the water procurement, waste management, by products, and recycling sectors became one of the base sectors in Pontianak City. However, the results of shift-share analysis on the competitive advantage component (Cij) showed the sector was moving more slowly than the Provincial level. Policies are needed to accelerate the growth of the water management sector, one of which is a policy to overcome the problem of flooding and inundation in Pontianak city and concomitantly strengthen its economic structure. The results of the AHP analysis showed the selected form of LID application, namely water tanks, rain gardens, bioretention, filter strips, infiltration trenches, porous pavement, and infiltration wells that lead to small-scale or self-contained applications. Sensitivity analysis shows that the criteria for land needs are very sensitive and most affect other measures, namely cost, in determining LID application. Therefore, the commitment of the Pontianak City Government as a regulator, dynamic actor, and facilitator is needed to support policies and budgets that strengthen the economic structure of Pontianak City as well as a cross-sectoral working atmosphere and healthy investment to support the implementation of LID
