Abstract

Floods are an annual disaster that disrupt public services and cause financial losses. Climate change and urbanization are the main factors contributing to increased rainfall which challenges the capacity of conventional drainage systems. The aim of writing this article is to analyze the depth, inundation area and flow direction in the superblock development plan using HEC-RAS 2D hydraulic modeling. The method used is to combine hydrological analysis, namely calculating the rainfall distribution using the Gumbel method, with hydraulic modeling. Hydrological analysis is conducted to calculate the frequency analysis of return periods and peak flood discharge. The return period rainfall using the Gumbel method for a 5-year return period (R5) is 212.921 mm. The flood discharge was calculated using the Rational method with catchment area 12.96 ha, resulting in Q = 1.08 m³/s. In calculating the Rational peak discharge, a rainfall intensity value is needed. The rain intensity required in the Rational method calculation uses the IDF curve to obtain a value of 100.6 mm/hour. The rain intensity value is then processed using an equation and the planned peak discharge is produced. Then peak flood discharge data is inputted and simulated using two-dimensional hydraulic modeling with HEC-RAS version 6.3.1 to obtain flood water surface profiles, inundation area and flow direction. The height of the flood inundation resulting from twodimensional hydraulic modeling using HEC-RAS 6.3.1 is 42 cm, the inundation area is approximately inundation area is around 8.5 ha, and the flow direction during flooding is towards the east of the project site.

Abstract

Degradasi lingkungan dan kedaruratan krisis sampah domestik di Indonesia merefleksikan kegagalan hukum tata lingkungan yang didominasi oleh paradigma antroposentrisme-sekuler. Penegakan hukum yang berorientasi hulu ke hilir (end-of-pipe approach) terbukti mandul karena memisahkan status kewarganegaraan dari kewajiban menjaga alam. Di sisi lain, Indonesia memiliki modalitas filosofis tertinggi (Staatsfundamentalnorm), yaitu Sila Pertama Pancasila, yang memuat dimensi ekoteologi universal namun kerap diredusir sebatas instrumen sosiopolitik keagamaan formal. Penelitian ini bertujuan untuk mendekonstruksi bias antroposentrisme hukum modern melalui pembentukan konsep Ecological Citizenship (Kewarganegaraan Ekologis) berbasis Sila Pertama Pancasila serta merumuskan model aktualisasi normatifnya dalam hukum tata lingkungan nasional. Penelitian ini merupakan penelitian hukum normatif (doktriner) dengan menggunakan pendekatan filosofis (philosophical approach), pendekatan konseptual (conceptual approach), dan pendekatan perundang-undangan (statute approach). Analisis bahan hukum dilakukan secara kualitatif melalui penalaran deduktif-silogisme dan hermeneutika hukum. Hasil penelitian menunjukkan bahwa: Pertama, secara ontologis, epistemologis, dan aksiologis, Sila Pertama Pancasila merupakan akar filosofis Pancasila based Eco-Citizenship yang menetapkan bahwa menjaga alam adalah mandat profetik dan kewajiban kodrati-transendental, di mana pengrusakan lingkungan diklasifikasikan sebagai "dosa ekologis" (ecological sin). Kedua, aktualisasi konsep ini dilakukan melalui redefinisi hak dan kewajiban konstitusional (constitutional duties) secara simetris dalam konstitusi hijau (green constitution), mengonversi pemilahan sampah di hulu menjadi norma hukum memaksa (imperative norms) pada legislasi nasional pasca UU Cipta Kerja, serta mengoperasionalisasikannya di tingkat daerah melalui Perda berbasis mekanisme sanksi ketidaklayakan sipil (civil disqualification) dan insentif fiskal. Kata Kunci: Ecological Citizenship, Ekoteologi, Hukum Tata Lingkungan, Sila Pertama Pancasila. ABSTRACT Environmental degradation and the domestic waste crisis emergency in Indonesia reflect the failure of environmental law, which is dominated by a secular-anthropocentric paradigm. The end-of-pipe law enforcement approach has proven ineffective because it detaches the status of citizenship from the obligation to preserve nature. On the other hand, Indonesia possesses its highest philosophical modality (Staatsfundamentalnorm), namely the First Principle of Pancasila, which embodies universal eco-theological dimensions but is frequently reduced to a mere sociopolitical instrument of formal religion. This study aims to deconstruct the anthropocentric bias of modern law by conceptualizing a Pancasila-based Ecological Citizenship derived from the First Principle and formulating its normative actualization models within the national environmental law system. This study is a normative (doctrinal) legal research employing a philosophical approach, a conceptual approach, and a statute approach. Legal materials were analyzed qualitatively through deductive-syllogism reasoning and legal hermeneutics. The results indicate that: First, ontologically, epistemologically, and axiologically, the First Principle of Pancasila serves as the philosophical root for a Pancasila based Eco-Citizenship, establishing that preserving nature is a prophetic mandate and a natural-transcendental duty, thereby classifying environmental destruction as an "ecological sin." Second, the actualization of this concept is achieved through a symmetrical redefinition of constitutional rights and constitutional duties within a green constitution, converting upstream waste segregation into imperative norms in national legislation post Job Creation Law, and operationalizing it at the regional level via local regulations utilizing civil disqualification mechanisms alongside fiscal incentives. Keywords: Ecological Citizenship, Environmental Law, Eco-Theology, First Principle of Pancasila.

Abstract

Corn tortilla production in Mekar Damai Village, Praya District, Central Lombok Regency, still relies on conventional sun drying, making the process highly dependent on weather conditions and increasing the risk of product contamination. This community service activity aimed to introduce and implement a solar dryer to improve the efficiency and hygiene of the corn tortilla drying process and to enhance the partners’ knowledge and skills in operating the dryer. The activity was conducted on August 14, 2026, through preparation, socialization, training, technology implementation, mentoring, and evaluation. The dryer measured 2.65 m × 1 m and was covered with UV plastic to utilize solar radiation through the greenhouse effect. The drying chamber was equipped with four rack levels, each containing eight trays measuring 40 × 60 cm, providing a total of 32 trays and an effective drying area of 7.68 m². Training was conducted through demonstrations and hands-on practice covering product arrangement on trays, dryer operation, monitoring of drying conditions, and equipment maintenance. Evaluation using pre-test and post-test assessments indicated an improvement in the partners’ knowledge and understanding of drying technology after the training. The implementation of the solar dryer provided a more protected and controlled drying process compared with conventional open sun drying. This technology is expected to support a more efficient, hygienic, and consistent corn tortilla production process and encourage the sustainable adoption of appropriate drying technology by the partner group.
