Penerapan teknologi penanganan pascapanen kedelai merupakan salah satu cara untuk meningkatkan kuantitas dan kualitas produksi komoditas kedelai. Kehilangan hasil terjadi pada setiap kegiatan penanganan pascapanen. Kehilangan hasil dapat secara kuantitatif (susut bobot) maupun kualitatif (susut mutu). Tujuan dilakukan pengkajian penerapan teknologi pascapanen yang baik adalah untuk menekan kehilangan hasil dan mempertahankan mutu kedelai. Pengkajian dilakukan di 5 (lima) kecamatan di Kabupaten Bantul dengan luas lahan tanam kedelai 8 hektar. Varietas kedelai yang digunakan adalah Anjasmoro yang telah bersertifikat. Teknologi pascapanen yang digunakan yaitu cara eksisting petani dan teknologi introduksi BPTP Yogyakarta. Hasil dari penerapan pascapanen kedelai baik di kabupaten Bantul yaitu kadar air kedelai sudah mencapai 10-13 %, sedangkan biasanya petani memanen ketika kadar air masih diatas 14%. Untuk kehilangan hasil saat panen mengalami penurunan 0,61%-1,18% setelah menerapkan cara panen yang diintroduksikan. Kapasitas kerja pemanen satu orang pekerja dengan cara rekomdasi mencapai 123,6-156,47 m2/jam, sedangkan cara petani mencapai 116,7-132,74 m2/jam. Untuk hasil panenan biji kedelai kering untuk lokasi demplot rata-rata mencapai 1,41 ton/ha, sedangkan cara petani hanya mencapai 1,02 ton/ha. Untuk mutu kedelai yang dihasilkan di lokasi demplot persentase butir utuh mencapai 80,15-91,53% sedang cara petani hanya 42,4%-67,54%. Untuk butir hijau panenan lokasi demplot mencapai 0,25-1,63% sedangkan cara petani mencapai 3,27-13,59%.","PeriodicalId":253602,"journal":{"name":"Proceedings Series on Physical & Formal Sciences","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131712174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study applied a factorial randomized block design (RAK) method consisting of 2 factors, namely variations in treatment days and variations in oil palm trees with a planting age of 10 years with 2 replications. Observation parameters include free fatty acid content and water content referring to the quality standard of CPO (Crud Palm Oil) in SNI. Determining the harvest time of oil palm fruit in the garden is carried out based on the level of maturity of the fruit. Determining the maturity of oil palm fruit is often referred as a fraction, but harvesters still use the method of fruit maturity degree by brondolan on the land before the bunch is cut. This brondolan is an indicator of suitable palm fruit for harvesting. The ALB content of the brondolan on the first day to the sixth day was analyzed with the standard method. The results of the free fatty acid content (ALB) according to the SNI standard are a maximum of 5% and the maximum factory standard of 3%. The effective or appropriate harvest time for harvesting oil palm fruit in smallholder plantations is on the first day <3%, resulting when the palm fruit arrives at the factory, it is still with ALB content that is in accordance with predetermined quality standards.","PeriodicalId":253602,"journal":{"name":"Proceedings Series on Physical &amp; Formal Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115832929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dalam upaya pemenuhan kebutuhan rumah tangga, petani juga dihadapkan pada produktivitas hasil produksi yang cenderung menurun. Salah satu upaya meningkatkan produktivitas adalah dengan peremajaan terhadap tanaman karet yang mana menjadi usaha dimana dapat memberikan kontribusi untuk penerimaan rumah tangga petani karet. Peremajaan kebun karet milik petani diduga memberikan pengaruh pada penerimaan rumah tangga. Petani akan memutuskan melakukan peremajaan dengan asumsi bahwa kebutuhan rumah tangga mereka dapat terpenuhi. Penelitian ini bertujuan untuk mendeskripsikan usahatani karet petani dan menganalisa penerimaan dan pengeluaran rumah tangga petani pasca peremajaan. Ruang lingkup penelitian dilakukan di 5 desa yaitu Napal Sisik, Sridadi, Pasar Terusan, Rambahan dan Rantau Puri pada kecamatan mauara bulian Kabupaten Batanghari dengan jumlah petani 47 sampel petani. Pemilihan daerah penelitian didasarkan atas pertimbangan bahwa 5 desa tersebut merupakan daerah yang paling banyak melakukan peremajaan dilihat dari luas lahan. Analisa data yang digunakan ialah analisa deskriptif dengan menggambarkan usahatani karet petani dan analisa kuantitatif dengan menghitung penerimaan dan pengeluaran rumah tangga petani karet pasca peremajaan. Hasil penelitian menjelaskan bahwa luas lahan kebun karet rata-rata 3 ha dengan produksi 680,35 kg/ha/thn yang menggunakan bibit pada klon unggul. Penerimaan rumah tangga petani diperoleh dari kegiatan on farm dan off farm dimana total penerimaan yang diterima sebesar Rp. 74.637.446,81/thn. Sementara pengeluaran rumah tangga petani meliputi pengeluaran konsumsi rumah tangga yang dihitung dari pengeluaran sandang, pangan, perumahan, pendidikan dan kesehatan dengan total pengeluaran sebesar Rp.34.080.000,-/thn. Pengeluaran rumah tangga dari sisi usahatani adalah pengeluaran yang dikeluarkan petani dalam usahatani karet dan usahatani kelapa sawit. Selain itu peremajaan lahan karet merupakan salah satu bagian pengeluaran rumah tangga petani sebesar Rp. 26.499.109,12/thn sehingga pengeluaran keseluruhan dari rumah tangga petani sebesar Rp. 60.579.109,12/thn. Penerimaan rumah tangga petani yang memberikan selisih lebih besar (positif) dari pengeluaran rumah tangga, menunjukkan bahwa sebaiknya petani lebih memafaatkannya sebagai penambahan penerimaan rumah tangga dengan memanfaatkan sumber daya sumber daya sebagai tambahan penerimaan di masa mendatang.
