Abstract

Water availability is a crucial factor that must be considered in the planning and management of irrigation systems. This study aims to determine water requirements based on a proposed rice–rice–secondary crops cropping pattern in the Oepunu Irrigation Area. This irrigation area encompasses 111 hectares of functional land and 20 hectares of potential land, with the current cropping pattern being rice–secondary crops. To ensure sufficient water supply, a study is necessary to design an effective cropping pattern. This research employed the Modified Penman method to calculate evapotranspiration, the F.J. Mock method to estimate dependable discharge, and direct streamflow measurements. The dependable discharge obtained ranges from 1,02 to 8,38 m³/s. The average discharge from direct measurements during the dry season (May-II to July-II) was 0,26 m³/s. The irrigation water requirements for the alternative cropping patterns are as follows: Alternative I ranges from 0,02–0,32 m³/s, Alternative II from 0,03–0,30 m³/s, and Alternative III from 0,03–0,24 m³/s. Based on the calculations, the maximum irrigable land area is 316.49 hectares for Alternative I, 274.95 hectares for Alternative II, and 948.87 hectares for Alternative III. These figures exceed the available land area, indicating that the selection of a cropping pattern must be based on the planned discharge derived from both irrigation water requirement calculations and field measurements. The planned discharge values are 0,32 m³/s for Alternative I, 0,30 m³/s for Alternative II, and 0,24 m³/s for Alternative III. Based on these planned discharge values, the most suitable cropping pattern is Alternative III, with a planned discharge of 0,24 m³/s and measured available discharge of 0,26 m³/s.

Abstract

The road is an important land transportation infrastructure, so a good pavement design is a must because poor road conditions can affect traffic performance. This study aims to determine the impact of road damage on traffic on the Timor Raya road segment Km 28, Oesao, Kupang Regency. Road damage analysis was conducted using the PCI method on three road segments, and traffic analysis used the PKJI 2023 method. The research results show the of road damage in segment I: 69.1 (Fair), segment II: 86,2 (Good), and segment III: 94,1 (Good). Vehicle volume during peak hours was segment I: 1641.4 smp/jam, segment II: 1510.4 smp/jam, and segment III: 1076.3 smp/jam. Side friction during peak hours was segment I: 975.6 kej/jam, segment II: 591.4 kej/jam, and segment III: 1056.4 kej/jam. Vehicle speed on a good road was segment I: 46 km/jam, segment II: 44 km/ jam, and segment III: 45 km/ jam. Vehicle speed on a damaged road was segment I: 37 km/ jam, segment II: 36 km/ jam, and segment III: 44 km/ jam. The impact on traffic is that it can cause congestion at points of damage and affect vehicle speed.

Abstract

Abstrak Ketersediaan lahan di daerah perkotaan saat ini untuk pertanian terbatas, karena peralihan lahan menjadi perumahan dan fasilitas umum yang menunjang di daerah perkotaan. Sedangkan kebutuhan bahan pangan, khususnya sayuran bagi kebutuhan konsumsi rumah tangga terus meningkat. Di saat pandemi covid-19 yang sedang mewabah, maka perlu meningkatkan daya tahan tubuh dengan mengkonsumsi sayur sehat. Kegiatan program kemitraan masyarakat ini, mencoba mengenalkan kepada masyarakat khususnya kelompok Anugerah kaum perempuan rayon 12 Gereja Masehi Injili di Timor (GMIT) Pohonitas Manulai II Kota Kupang tentang pemanfaatan lahan terbatas menggunakan sistem hidroponik baskom untuk menanam sayur guna pemenuhan kebutuhan konsumsi sayur rumah tangga. Metode hidroponik dapat dikembangkan dan diaplikasikan disektor rumah tangga atupun skala besar untuk peningkatan perekonomian masyarakat. Sistem hidroponik baskom relatif mudah untuk diterapkan di kalangan Ibu rumah tangga, karena sistem penanaman sayur tidak menggunakan media tanah melainkan menggunakan media air bernutrisi yang diletakkan dalam baskom, sehingga sayuran dapat tumbuh dengan baik karena akar menyerap unsur-unsur hara yang diperlukan. Hasil kegiatan memberikan pemahaman dan pelatihan tentang pentingnya mengoptimalkan lahan pekarangan agar mandiri dalam menghasilkan kebutuhan sayuran sehat untuk konsumsi rumah tangga. sehingga diharapkan dengan pelatihan penanaman sayuran menggunakan metode hidroponik baskom dapat memberikan solusi penyediaan sayuran sehat pada lahan terbatas di daerah perkotaan. Abstract The availability of land in urban areas is currently limited for agriculture, due to the shift of land into housing and supporting public facilities in urban areas. Meanwhile, the need for food, especially vegetables for household consumption needs continues to increase. During the COVID-19 pandemic, it is necessary to increase endurance by consuming healthy vegetables. This community partnership program activity tries to introduce to the community, especially the Anugerah women group of the 12 Evangelical Christian Church in Timor (GMIT) Pohonitas Manulai II Kupang City about the use of limited land using a basin hydroponic system to grow vegetables to fulfill household vegetable consumption needs. The hydroponic method can be developed and applied in the household sector or on a large scale to improve the community's economy. The basin hydroponic system is relatively easy to implement among housewives, because the vegetable growing system does not use soil media but uses nutritious water media that is placed in a basin, so that vegetables can grow well because the roots absorb the necessary nutrients. The results of the activity provide understanding and training on the importance of optimizing the yard so that it is independent in producing the needs of healthy vegetables for household consumption. so it is hoped that the training of vegetable planting using the basin hydroponic method can provide a solution for providing healthy vegetables on limited land in urban areas.
