Abstract

      This study underscores the urgent need for vocational education in Kotawaringin, Central Kalimantan, to meet industry demands and public expectations for accessible and high-quality education. The findings indicate a strong interest in vocational training aligned with local industries, with the majority of respondents (67.79% male) recognizing its role in workforce preparedness. Most 11th-grade students (46.21%) prefer entering the workforce immediately after graduation (61.05%), particularly in the mining sector (30.06%), due to financial constraints and concerns regarding university graduates' employment prospects. The majority of respondents come from SMKN 2 Sampit (37.94%) and SMKN 1 Pangkalan Lada (36.09%). Bridging the gap between career preferences and labor market needs requires awareness campaigns, scholarships, internships, and industry partnerships. Key strategies include strengthening school-industry collaboration, enhancing infrastructure, developing competency certification programs, improving teacher training, promoting curriculum flexibility, and expanding financial aid. Broadening financial assistance is crucial for accessibility. These measures are expected to equip graduates with relevant skills, foster regional economic growth, and strengthen the sustainability of the workforce.

Abstract

The purpose of this study was to determine the best dose of PSB application on the growth of caisim plants in inland peat soil, and to determine the yield of caisim plants after PSB application in inland peat soil. This research was conducted in the field of Department of Agricultural Cultivation, University of Palangka Raya. This research was conducted from February 28, 2025 to April 28, 2025. This study used a single-factor Completely Randomized Design (CRD), namely the application of PSB (ml L-1) consisting of 5 treatment levels, namely: control, 25, 50, 75, and 100. Each treatment was repeated 4 times, resulting in 20 experimental units. The results showed that the application of PSB had a significant effect on the observation variables of plant height at all ages, number of leaves at 21 HST and 28 HST, plant fresh weight and plant dry weight. PSB application did not significantly affect the observation variables of the number of leaves at the age of 14 HST, leaf area and plant root weight. PSB application with a concentration of 100 ml L-1 =A4 gives the best results in all observations.

Abstract

Penelitian ini dilakukan untuk melihat sejauh mana fungsi ekologi, sosial budaya dan estetika yang harus diperankan oleh RTH publik dilakukan secara optimal pada kawasan permukiman kota Puruk Cahu. RTH publik yang diteliti sebanyak 4 (empat) lokasi pada 2 (dua) kecamatan yaitu Kecamatan Murung dan Kecamatan Tanah Siang Selatan. Pemilihan lokasi mempertimbangkan pada wilayah kecamatan, luasan, kemanfaatan fungsi ekologis, sosial budaya dan estetika yang ada. Teknik analisis data yang dipakai dalam penelitian adalah deskriptif dengan pendekatan kuantitatif yang terdiri dari studi literatur, telaah dokumen, observasi, kuisioner dan wawancara. Penelitian ini menggunakan 3 variabel dan 10 sub variabel dengan perhitungan skala linkert dari hasil kuisioner 30 responden. Hasil Penelitian menunjukkan RTH publik Alun-Alun Kota, Taman Pasir Putih dan Hutan Bumi Perkemahan bearada pada kawasan Area Penggunaan Lain (APL) dan RTH TPU Lowu Tatou berada di Hutan Produksi Konversi (HPK). RTH TPU Lowu Tatou di Kecamatan Murung tidak termasuk dalam wilayah RDTR karena dalam lingkup perencanaan RDTR hanya mengambil sebagian wilayah desa Danau Usung. Secara fungsional dalam fungsi ekologi, sosial budaya dan estetika RTH sudah berfungsi dengan baik. Potensi sosial budaya paling dominan memenuhi kebutuhan masyarakat pada keempat RTH publik. Potensi ekologis menempati urutan kedua diikuti oleh potensi estetika. Potensi RTH berdasarkan hasil observasi untuk seluruh indikator ada yang terpenuhi dan tidak terpenuhi.

Abstract

Penelitian ini bertujuan menganalisis sifat fisik dan kimia tanah menurut umur reklamasi dan rona awal lingkungan pada lokasi penelitian yaitu lokasi bekas penambangan bauksit dalam wilayah izin usaha pertambangan PT. Citra Mentaya Mandiri dan PT. Duta Borneo Pratama. Hasil analisa laboratorium terhadap sampel tanah pada 5 (lima) lokasi dengan ketebalan 0-20 cm yakni rona awal, lokasi belum reklamasi, reklamasi 1 tahun, reklamasi 2 tahun, dan reklamasi 5 tahun. Analisis data menggunakan uji sidik ragam dan uji lanjutan BNT (Beda Nyata Terkecil). Hasil penelitian ditemukan perbedaan sifat fisik dan kimia tanah menurut umur reklamasi dan rona awal lingkungan, namun tidak berbeda nyata terhadap kapasitas tukar kation pada lokasi tersebut. Kondisi sifat fisik tanah ditemukan pencampuran antara lapisan tanah atas dengan lapisan tanah bagian bawah akibat penambangan dan penimbunan tanah. Tekstur tanah berupa liat berdebu - lempung berpasir. Struktur tanah berupa gumpal bersudut - gumpal membulat dengan ukuran pasir berdebu dan tingkat perkembangan sukar hancur - mudah hancur. Penurunan bobot isi tanah akibat presentase fraksi, penambahan bahan organik, vegetasi, dan aktivitas fauna yang berbeda. Kondisi sifat kimia tanah yaitu pH tanah tergolong asam berkisar antara 3,71 – 4,91. Penurunan kandungan N-total, P-total, C-organik mengalami penurunan disebabkan karena pH tanah yang asam, kurangnya vegetasi dan bahan organik. Perbedaan nilai Kalium dan Kejenuhan Basa disebabkan jumlah kandungan unsur hara dipengaruhi oleh serapan unsur hara, pencucian, jenis pupuk dan jumlah pupuk yang diberikan. Kapasitas tukar kation bervariasi nilainya tetapi tidak berbeda nyata, diduga karena kekurangan bahan organik pada lokasi reklamasi. Rekomendasi dalam pengelolaan tanah antara lain penambahan bahan organik, vegetasi dan unsur hara agar terjadi proses humifikasi dan dekomposisi tanah dapat meningkat.

Abstract

Law Number 18 of 2008 concerning Waste Management requires the closure of landfills with an open dumping system and replacing them with a sanitary landfill system, thus requiring a fairly large landfill cover layer. On the other hand, the amount of wood ashes produced in Indonesia is very abundant and has been widely used as an adsorbent and pozzolan material. Wood ashes has the potential to be used as a landfill cover material based on sanitary landfills, especially daily cover and intermediate cover. This research has purpose to analyze the differences in surface area and silica content contained in laterite soil and wood ashes, analyze differences in the volume of leachate produced from the use of wood ashes and laterite soil as a landfill cover layer, analyze the effect and whether the use of wood ashes as a cover layer material TPA produces better quality TSS (total suspended solid), TDS (total dissolved solid), and Pb (lead) than using laterite soil. This research was carried out by using 3 lysimeters, that is a lysimeter without a covered layer, a lysimeter with a laterite covered layer, and a lysimeter with a wood ash covered layer. The results of the research show that the surface area of wood ashes and laterite soil has a similar surface area, but the Si content in wood ashes is higher than in laterite soil. The lysimeter with a covering layer of wood ash produces a smaller volume of leachate than the volume of leachate from other lysimeter variants, lysimeters with wood ashes cover layers have a negative effect on TDS concentrations so they will produce higher TDS concentrations compared to lysimeters that use laterite soil cover layers and have a positive effect on TSS and Pb concentrations so they will produce TSS concentrations and lower Pb compared to lysimeters that use a laterite soil cover layer. Lysimeter with a laterite cover layer have a negative effect on the TSS concentration of leachate so that they will produce a higher TSS concentration compared to the TSS cocentration of leachate from lysimeter without a cover layer and lysimeter with a wood ash cover layer.
