Abstract

Polder Liang yang berletakak ada di sebelah barat kota Martapura di desa tambak baru Kabupaten Banjar, Provinsi Kalimantan Selatan. Luas polder lebih dari 900 Ha dikelilingi jalan sebagai tanggul polder liang berada di tiga kecamatan yaitu Kecamatan Matapura, Karang Intan, Astambul. Polder liang memiliki beberapa pintu air yaitu 6 pintu air utama dan 29 pintu air kecil. Sistem pintu air yang ada di sekitaran polder masih bersifat manual. Perhitungan ini menggunakan metode Nreca untuk perhitungan debit andalan dan debit nreca dan metode panmen dan standar KP-01 untuk perhi tungan kebutuhan air pada BAB IV dan menghitung pengembangan lahan pertanian berdasarkan neraca air.Hasil Perhitungan kebutuhan air yang ada di desa tambak baru kecamatan martapura kabupaten banjar kebutuhan air tertinggi pada bulan juni II berjumlah dengan rata-rata 0,442 m3/detik ketersedian air dihitung dengan debit andalan 80% didapat rata-rata ketersedian air 31,095 dengan awal pola tanam digunakan juni II perhitungan neraca air yang ada di petak sawah pada bulan juni II 5,384 m3/detik.perhitungan perkembangan lahan yang awalny tercatat 638 Ha bisa di kembangkan menjadi 845 Ha.

Abstract

Latar Belakang Sejarah Majunya Peradilan di Indonesia Paa Periode Pra-Imperialisme dan Ekspansionisme (Belanda, Jepang, Mitra). Artikel ini membahas latar belakang Sejarah perkembangan sistem peradilan di Indonesia pada periode pra-imperialisme dan ekspansionisme oleh Belanda, Jepang, dan Mitra. Fokus utama artikel ini adalah menjelaskan bagaimana peradilan di Indonesia berkembang di bawah kekuasaan masing-masing kolonial dan pendudukan asing. Penelitian ini didasarkan pada referensi sejarah dan literatur hukum yang relevan. Melalui analisis sejarah, artikel ini bertujuan untuk memberikan gambaran yang komprehensif mengenai perjuangan dan perubahan yang dialami sistem peradilan Indonesia pada periode ini.Kata Kunci : Peradilan, Sejarah, Pra-imperialisme, Belanda, Jepang, Mitra.

Abstract

The application of CNC technology in the furniture industry has already become familiar, in addition to its use in the metal and plastic industries. HMR (High Moisture Resistant) panels, which had better moisture resistance than MDF (Medium Density Fiberboard), had also started to develop. However, few studies have investigated the effects of variations in machining parameters on the cutting quality of HMR boards. This study aimed to test the effects of machining parameters (cutting method and cutting depth) on the dimensions and surface roughness of the workpiece. Four schemes of machining parameter settings, namely conventional and climb methods with cutting depths of 2 mm and 4 mm, respectively, were performed with three repetitions each. After testing, it was found that the cutting method, cutting depth, and the interaction between the cutting method and cutting depth had not significantly affected the length and width dimensions of the specimen. However, the cutting method significantly influenced the final surface roughness of the specimen. The conventional cutting method with a cutting depth of 2 mm produced the best surface roughness, measuring 26.47 µm.

Abstract

This study investigates the influence of cutting methods and feed rates on the dimensional accuracy and surface roughness of HMR (High Moisture Resistance) panels. The aim is to determine the optimal cutting parameters that yield precise dimensions and smooth surfaces in CNC machining. Two cutting methods—single and double passes—were applied using feed rates of 2, 4, and 6 m/min. Dimensional accuracy was measured using a digital caliper, while surface roughness was evaluated with a surface tester. The results indicate that the double-pass cutting method significantly improves both dimensional accuracy and surface finish. Statistical analysis using ANOVA revealed that feed rate has a significant effect on surface roughness (p < 0.05), whereas dimensional accuracy is primarily influenced by the cutting method. These findings provide practical insights for optimizing CNC machining processes in furniture manufacturing using HMR panels.
