Abstract

The calculation of crop productivity has now been facilitated by technological development using remote sensing technology or data generated by satellites. Determining the value of productivity using images will shorten the time and does not require much effort. A remote sensing model that connects satellite image reflectance data with rice plant parameters will be handy for monitoring biomass growth and predicting crop yields more quickly and efficiently. This study aimed to determine the regression equation to estimate the productivity of regional rice in Harau District, Lima Puluh Kota Regency. This study consisted of several stages: data collection, data processing, and calculation of rice productivity, NDVI regression analysis with rice productivity, and Nash-Sutcliffe Efficiency (NSE) test against the obtained equations. The regression equation obtained from the results of data analysis to estimate rice productivity in Harau District, Lima Puluh Kota Regency is y = - 82152x4 + 208465x3 - 197654x2 + 82986x - 13014, with an NSE value of 0.64 which is categorized as ‘sufficient’.Keywords: MODIS, NDVI, Rice, Remote sensing; Productivity

Abstract

Rice productivity is closely related to rice harvested area and cropping intensity. Remote sensing technology using MODIS MOD13A1 v006 image produces Normalized Difference Vegetation Index (NDVI) values that can be interpreted in analyzing the value of rice productivity. Gunung Talang District has a rice field area of 3,369 m2, which is one of the central rice areas in West Sumatra Province. This study aimed to determine the regression equation to estimate rice productivity in Gunung Talang District, Solok Regency using the NDVI algorithm. The NDVI data used to generate the regression equation was taken in the generative phase. From the results of data analysis, the regression equation for estimating rice productivity in Talang District, Solok Regency is y = 250.33x4 - 1493.3x3 + 2293.6x2 - 1353.9x + 281.13, where x is the NDVI value and y is the productivity value (ton ha-1). The test results of the model's validity are expressed in the value of NSE (Nash-Sutcliffe Efficiency) is 0.66, which is categorized as adequate.

Abstract

Legal certainty over nagari administrative areas is a crucial element in the nagari governance system. A base map in the form of imagery is needed to streamline the process of confirming and determining boundaries between bordering nagari. Drone technology is an effective solution in taking aerial photographs that can be used as a base image for drawing administrative boundaries. Nagari Sikucua Barat, located in Padang Pariaman Regency, currently does not have a clear legal basis for its administrative boundaries. This service activity aims to provide accurate and up-to-date base imagery to support the drawing of administrative boundaries legally and technically. In addition, this activity also increases the capacity of the village government in utilizing geospatial technology in order to systematically manage regional information. The result of this activity is the availability of the latest aerial imagery up to December 2024, replacing the previous High Resolution Upright Imagery (CTRT) which only includes data up to 2018. The impact of this activity includes increasing the efficiency of nagari administration, integrating assets and resources into a spatial data-based information system, and strengthening the legal basis of territorial boundaries. The service assistance will continue until the nagari has an interactive, integrated, and user-friendly information system to support data-based decision-making more accurately and transparently.   Abstrak Kepastian hukum terhadap wilayah administrasi nagari merupakan elemen krusial dalam sistem pemerintahan nagari. Peta dasar berupa citra sangat diperlukan untuk mengefisiensi proses penegasan dan penetapan batas antar nagari sempadan. Teknologi drone menjadi solusi efektif dalam pengambilan foto udara yang dapat digunakan sebagai citra dasar untuk penarikan garis batas wilayah administrasi. Nagari Sikucua Barat, yang terletak di Kabupaten Padang Pariaman, hingga saat ini belum memiliki dasar hukum yang jelas terkait batas wilayah administrasinya. Kegiatan pengabdian ini bertujuan menyediakan citra dasar yang akurat dan mutakhir guna mendukung penarikan garis batas wilayah administrasi secara legal dan teknis. Selain itu, kegiatan ini juga meningkatkan kapasitas pemerintah nagari dalam pemanfaatan teknologi geospasial agar dapat mengelola informasi wilayah secara sistematis. Hasil kegiatan ini adalah tersedianya citra udara terbaru hingga Desember 2024, menggantikan Citra Tegak Resolusi Tinggi (CTRT) sebelumnya yang hanya mencakup data hingga tahun 2018. Dampak kegiatan ini meliputi peningkatan efisiensi administrasi nagari, integrasi aset dan sumber daya ke dalam sistem informasi berbasis data spasial, serta penguatan dasar hukum batas wilayah. Pendampingan pengabdian akan berlanjut hingga nagari memiliki sistem informasi yang interaktif, terintegrasi, dan ramah pengguna guna mendukung pengambilan keputusan berbasis data secara lebih akurat dan transparan.

Abstract

Penelitian ini bertujuan untuk mengevaluasi stabilitas tebing sungai dalam rangka proyek pembangunan sarana dan prasarana pengendalian banjir Batang Lembang (Tahap II) yang berlokasi di Solok, Sumatera Barat. Proyek ini mencakup tiga lokasi utama, yaitu Selayo di Kabupaten Solok (BH01), VI Suku di Kota Solok (BH02), dan KTK di Kota Solok (BH03). Analisis stabilitas lereng dilakukan menggunakan metode slope/w dan faktor keamanan yang mengacu pada SNI 8640-2017 mengenai "Persyaratan Perancangan Geoteknik". Berdasarkan hasil analisis, faktor keamanan pada beberapa kondisi di lokasi Selayo dan VI Suku tidak memenuhi standar minimum yang ditetapkan, sementara di lokasi KTK, faktor keamanan menunjukkan hasil yang sesuai dengan persyaratan. Penelitian ini juga mengusulkan modifikasi terhadap geometri lereng dan penambahan elemen perkuatan, seperti cerucuk dolken, untuk meningkatkan stabilitas tebing di lokasi yang tidak memenuhi syarat. Selain itu, evaluasi dilakukan terhadap potensi modifikasi penampang sungai untuk memperbaiki kestabilan lereng, dengan fokus pada perubahan geometri dan penambahan elemen perkuatan. Hasil analisis menunjukkan bahwa dengan penerapan modifikasi tersebut, beberapa lokasi yang sebelumnya tidak memenuhi standar faktor keamanan dapat diperbaiki, sehingga sesuai dengan ketentuan geoteknik yang berlaku. Temuan dari penelitian ini memberikan rekomendasi teknis untuk meningkatkan stabilitas tebing sungai, yang diharapkan dapat memberikan kontribusi penting terhadap kelancaran pembangunan sarana dan prasarana pengendalian banjir yang aman dan berkelanjutan di kawasan Batang Lembang. Penelitian ini juga menawarkan wawasan mengenai penerapan standar geoteknik terbaru dan menekankan pentingnya analisis kondisi lokal dalam merancang solusi mitigasi bencana banjir yang efektif. Selain itu, hasil penelitian ini dapat menjadi acuan bagi perencanaan pembangunan serupa di wilayah lain dengan karakteristik yang serupa.

Abstract

Road infrastructure is a crucial element in supporting socio-economic growth, particularly in rural areas such as Nagari Lawang, Agam Regency, West Sumatra. This article discusses efforts to map road conditions in Nagari Lawang using Geographic Information Systems (GIS). The objective of this mapping is to enhance road accessibility, which can support the economic growth of the local community, especially in the agriculture and tourism sectors. The methodology includes road accessibility surveys and data analysis using ArcGIS software. Survey results indicate that the roads in Nagari Lawang are predominantly concrete with an average width of 2 meters, while dirt roads are narrower and mainly used as farm roads. The resulting map is expected to assist the government in more targeted and equitable development planning. This road mapping not only supports infrastructure development but also aligns with the Merdeka Belajar Kampus Merdeka (MBKM) program as a collaborative effort in regional development to the head of the Lawang village government.

Abstract

Perubahan iklim dan aktivitas antropogenik menyebabkan tekanan signifikan terhadap sumber daya air, mempengaruhi keseimbangan ketersediaan dan kebutuhan air di berbagai daerah aliran sungai. Penelitian ini bertujuan mengevaluasi ketahanan sumber daya air (water resilience) di hulu DAS Batang Arau, Kota Padang dengan menggunakan pendekatan terpadu berbasis pemodelan hidrologi SWAT dan analisis Reliability, Resilience, Vulnerability (RRV). Metode penelitian meliputi: (1) karakterisasi morfometri DAS dengan menganalisis 19 parameter morfometri; (2) pemodelan SWAT dengan kalibrasi-validasi yang menghasilkan nilai performa bervariasi (R² = 0,54-0,97) dan sangat baik (NSE = 0,79-0,89); (3) analisis keseimbangan supply-demand; serta (4) evaluasi ketahanan air dengan pendekatan RRV. Hasil analisis morfometri menunjukkan DAS memiliki bentuk memanjang (Form Factor 0,25) dengan kerapatan drainase sedang (1,40 km/km²). Pemodelan SWAT menghasilkan debit andalan Q80 sebesar 1,51 m³/s yang masih mencukupi total kebutuhan air 0,63 m³/s (domestik 0,0234 m³/s; pertanian 0,4252 m³/s; industri 0,1811 m³/s), dengan Water Availability Ratio (WAR) 1,427. Analisis RRV menghasilkan Indeks Keberlanjutan DAS (IKDAS) sebesar 0,85 (sangat baik), didukung oleh keandalan tinggi (1,0), ketahanan baik (0,84) dengan tutupan hutan 87,9%, namun masih menghadapi kerentanan signifikan (0,65) terutama akibat tingkat erosi tinggi (385,6 ton/ha/tahun) dan area rawan banjir (34,63%). Rekomendasi pengelolaan meliputi teknik konservasi tanah-air, sistem peringatan dini banjir, perluasan zona riparian, dan penguatan kelembagaan pengelolaan kolaboratif untuk mengintegrasikan kepentingan berbagai pemangku kepentingan. Pendekatan RRV terbukti efektif untuk evaluasi komprehensif kondisi DAS dan perumusan prioritas intervensi strategis.
