Abstract. Chotimah HENC, Kresnatita S, Miranda Y. 2013. Ethnobotanical study and nutrient content of local vegetables consumed in Central Kalimantan, Indonesia. Biodiversitas 14: 106-111. People in Central Kalimantan consume vegetables collected from the wild or traditionally cultivated. Documentation effort of them is very important because the diversity of local vegetables is threatened with extinction due to the conversion of peat land and forest fires. This study aimed to determine the diversity of local vegetables in Central Kalimantan, its use as a vegetable and nutrient content of some vegetables. The method used was the exploration and interviews. Exploration was carried out in three districts, namely Palangkaraya, Pulang Pisau, and Seruyan. Sampling of plants was done randomly and selectively. Data analysis was performed descriptively. The results showed that we recorded 42 plant species belonging to 30 families. There were many vegetables processing: stir-fry, make into clear soup, a light coconut milk soup, acidic soup, or just consumed as fresh vegetables. Based on the nutritional value, Helminthostachys zeylanica (L.) Hook had a potential to be developed as vegetables or medicinal plant. It had the highest protein, carbohydrate and minerals, namely P, Fe, Na and K among the vegetables analyzed.
The current study was aimed to determine the effect of ameliorant on Pak choi (Brassica rapa chinensis) productivity, CO2 emissions, and factors affecting the rate of CO2 emission. The study was carried out using a non-factorial completely randomized design with seven treatments. The imposed treatment are without ameliorant (control), 10, 20, 30 ton ha-1 chicken manure, 4 ton ha-1 Dolomite + Chicken Manure @ 10 ton ha-1, Dolomite 4 ton ha-1 + Chicken Manure @ 20 ton ha-1 and Dolomite 4 ton ha-1 + Chicken Manure @ 30 ton ha-1. The variables observed are the chemical properties of peat soil, fresh and dry weight of pak choi, CO2 emissions, and factors that affect CO2 emissions. The results of the study revealed that the combination of Dolomite and chicken manure has a significant effect on the studied parameters and the combination of 4 ton ha-1 dolomite + 30 ton ha-1 chicken manure had the highest pH change (average of 6.36), highest productivity, and CO2 emission (344.42 mg cm-2hr-1). Results of the study can be concluded that Dolomite and chicken manure has a significant effect on the various growth parameters of B. rapa chinensis and the properties of the peat soil.
Kegiatan pelatihan diversifikasi produk olahan jagung manis telah dilaksanakan di Kelurahan Kalampangan Kota Palangka Raya. Keberhasilan pertanian lahan gambut Desa Kalampangan, salah satunya ditunjang oleh sektor hortikultura. Umumnya pemenuhan kebutuhan sayuran sekitar Kota Palangka Raya dipasok dari Desa Kalampangan. Desa Kalampangan merupakan sentral produksi jagung manis di wilayah Kota Palangka Raya. Luas areal penanaman jagung manis menempati urutan teratas yaitu seluas 205 ha dengan produksi sebesar 215 ton/ha. Produksi ini sesuai dengan deskripsi varietas jagung manis dataran rendah Kegiatan pengabdian ini telah dilaksanakan pada bulan September sampai Oktober 2019 dengan kelompok sasaran ibu - ibu petani Desa Kalamapnagan. Metode kegiatan meliputi : 1) Sosialisasi dan Penyuluhan, 2) Pelatihan dan demontrasi, 3) Pembinaan/ pendampingan, 4) Monitoring. Tujuan dari kegiatan pelatihan diversifikasi produk olahan jagung manis. berupa puding dan kue talam diharapkan menjadi rintisan wirausaha bagi ibu - ibu petani Desa Kalampangan, adapun untuk pengolahan produk makanan ini hanya perlu teknologi yang sederhana. Sedangkan kontribusi yang diberikan kepada ibu – ibu petani mitra adalah dengan pelatihan pembuatan dua produk makanan yang terbuat dari jagung manis (puding dan kue talam jagung manis), diharapkan menjadi rintisan wirausaha baru skala home industri sehingga dapat menambah pendapatan income keluarga sekaligus untuk konsumsi sendiri guna memenuhi gizi keluarga. Dari kegiatan pelatihan ini diharapkan dapat menjaga kestabilan harga jagung manis di tingkat petani serta ada nilai tambah dari hasil produk olahan jagung manis. Adapun kekurangan yang perlu diperbaiki guna menunjang keberlanjutan rintisan usaha produk olahan puding dan kue talam jagung manis adalah perlu perbaikan pada wadah/tempat kemasan produk. Produk hasil olahan yang dikemas dengan wadah/ tempat yang cantik dan menarik serta tertutup sangat mempengaruhi kualitas hasil produk yaitu meningkatkan daya tarik bagi pembeli dan lebih higienis serta meningkatkan harga jual. Dari hasil kegiatan pengabdian ini disarankan perlu dicari inovasi teknologi guna peningkatan waktu saji yang lebih tahan lama (produk tidak mudah basi) karena produk olahan puding dan kue talam hanya bertahan setengah hari saja
Mikroba agens hayati dari perakaran tanaman berpotensi untuk dimanfaatkan sebagai Biopestisida, baik sebagai biofungisida maupun bioinsektisida. Tujuan kegiatan ini adalah memberikan pelatihan kepada kelompok tani Rukun Bersama di Kota Palangka Raya agar mampu membuat biopestisida secara mudah dan murah untuk mengendalikan hama dan penyakit yang ramah lingkungan. Biopestisida merupakan alternatif mengurangi penggunaan pestisida kimia, sehingga dapat menghemat biaya usaha tani di masa Pandemi Covid 19. Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilaksanakan pada bulan Agustus hingga September 2021 pada Kelompok Tani Rukun Bersama yang berlokasi di Kelurahan Tanjung Pinang, Kota Palangka Raya, Kalimantan Tengah. Metode pengabdian masyarakat dengan cara diskusi interaktif, pelatihan secara langsung teknik isolasi agens hayati menggunakan umpan nasi dan umpan serangga larva ulat hongkong (Tenebrio molitor), pembuatan biopestisida formulasi padat dan formulasi cair. Hasil evaluasi menunjukkan bahwa 100% petani pengetahuannya meningkat terhadap mikroba agens hayati yang bermanfaat sebagai bahan pembuatan Biopestisida, seperti jamur Trichoderma sp., Beauveria sp. dan Metarhizium sp. yang diisolasi dari perakaran tanaman bambu, serai, sirih, pisang, cabai dan putri malu. Petani secara mandiri mampu membuat biopestisida formulasi padat dan cair, dengan tingkat kontaminasi pada substrat hanya sekitar 5 %, hal ini menunjukkan bahwa petani terampil melakukan proses isolasi dan perbanyakan subtrat dengan tingkat keberhasilan hingga 95%. Microbial biological agents from the root zone of plants have the potential to be used as biopesticides, both as bio fungicides and bioinsecticides. The purpose of the current activity is to make biopesticides easy and feasibly to control pests and diseases that are also environmentally friendly. Biopesticides are an alternative to reduce the use of chemical pesticides and save farming costs during the Covid-19 Pandemic. This Community Service activity was carried out from August to September 2021 at the Rukun Bersama Farmer Group in Tanjung Pinang Village, Palangka Raya city, Central Kalimantan province. Community service methods included interactive discussions, hands-on training on biological agent isolation techniques using rice bait and insect bait for Hong Kong caterpillar larvae (Tenebrio molitor), and the production of solid formulations and liquid formulations of biopesticides. The results of the evaluation showed that 100% of farmers' knowledge was increased about microbial biological agents that were useful as ingredients for making biopesticides, such as Trichoderma sp., Beauveria sp. and Metarhizium sp. isolated from the roots of bamboo, lemongrass, sirih (Piper betle), banana, chili and putri malu (Mimosa pudica). Farmers independently made solid and liquid biopesticide formulations with a substrate contamination level of about 5%. It showed that farmers were skilled in the process of isolation and substrate propagation with a success rate of up to 95%.
