West Sumatra-Indonesia has potential to plant coconut due to the coastal location, sunshine level with average temperature 27oC. Coconut is a very productive plant. Coconut dehusking is one of the process that takes a lot of time and energy. Most of the farmer still using human manual labour with the help of tools made of iron or wooden crowbar that is mounted standing vertically with the blade facing upward about 80 cm from the ground. To increase the number of coconut products, it is designed the coconut dehusker machine. The main component of the machine were two rollers that rotate each other in opposite directions with each roller embedded iron-shaped nails that work to tear the coconut husk. Each roller has a different rotational speed. This machine has dimensions of 98 cm x 51 cm x 95 cm. Roller length is 50 cm and diameter 4 inches. The power source of the machine is a 2 HP electric motor, the speed was reduced by using 2 speeds reducer with the ratio of 1:20 and 1:30 respectively. From the performance test of this machine can dehusk 100 coconuts per hour. The operational basic cost of the machine equal to Rp 129.89 per coconut (about 1 cent) and Break Event Point is 12.387 coconut per year from the result of the performance test. From the economic analysis machine can be concluded that the use of this machine is better when compared to human labour which has limitation to duration and capacity.

The objective of this research was to formulate a policy strategy for integrated pest management by using SWOT AHP methods (case study on vegetable cultivation in Lampung Province). This method used A’WOT; the combination of AHP (Analytical Hierarchy Process) analysis and SWOT (Strength-Weakness-Opportunity-Threat) analysis. The analysis result showed the main strength factors becoming the base for sustainable agricultural business were the availability of good structures and infrastructures both in production and marketing, and the availability of sufficient production structure (seeds) with good quality and quantity. The weakness factors becoming concern were dominantly lack of institutional funding (capital) for vegetable business, many problems in the integrated pest management (IPM) technology implementation stage, many problems in good agriculture practices (GAP), and numbers of families making their life as farmers. The opportunity factors were the availability of IPM and GAP technologies, growing campaign for consuming domestic products reducing import, and high government commitment to improve vegetable farmers’ welfare. The threats to concern were no protection operational base and farmer’s empowerment, very few institutional funding (capital) for vegetable business, and many problems in the GAP and technology implementation. Six strategies becoming priority in order were drafting the regulation and standard of operation that regulate IPM and GAP implementations; strengthening farmer’ institution, capital and agricultural insurance; drafting legality of operational protection and farmer’s empowerment; agricultural intensification in order to improve quantity, quality, safety, and environmental insight for food security and independency; optimization of technology transfer by socialization or education of IPM and GAP for vegetable crops; and inexpensive IPM system based controlling technology development and effective and efficient of alternative production structures.

Kacang tanah merupakan salah satu jenis kacang-kacangan yang mempunyai nilai gizi tinggi. Akan tetapi produksi kacang tanah di Indonesia masih rendah dibandingkan dengan negara lain. Untuk meningkatkan produktivitas kacang tanah perlu dilakukan penambahan nutrisi pada tanaman namun dengan mahalnya harga pupuk perlu dicari alternatif lain. Untuk itu dilakukan penelitian pemanfaatan abu limbah penyulingan serai wangi menjadi pupuk organik untuk meningkatkan produktivitas kacang tanah. Penelitian ini dilakukan di Kebun Percobaan Balittro Laing Solok sejak September sampai Desember 2017. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan yaitu pemberian abu limbah penyulingan serai wangi dengan dosis : 1) 200 g 2) 250 g 3) 300 g dan 4) 0 g pada 8 tanaman per plot diulang 6 kali. Benih kacang tanah ditanam dalam kantong berukuran 45 x 60 cm yang berisi media tanah dan pupuk kandang dengan volume 1 kg/kantong. Variabel yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah polong, bobot basah, bobot kering serta bobot kering/100 biji. Pengamatan pertumbuhan dilakukan setiap dua minggu dimulai tiga minggu setelah tanam. Hasil penelitian menunjukan bahwa pertumbuhan vegetatif dan produksi tanaman kacang tanah mempunyai perbedaan yang signifikan dari setiap dosis abu limbah penyulingan yang digunakan.

Mayura, Herwita Idris","doi":"10.32530/JAAST.V3I1.65","DOIUrl":"https://doi.org/10.32530/JAAST.V3I1.65","url":null,"abstract":"Kacang tanah merupakan salah satu jenis kacang-kacangan yang mempunyai nilai gizi tinggi. Akan tetapi produksi kacang tanah di Indonesia masih rendah dibandingkan dengan negara lain. Untuk meningkatkan produktivitas kacang tanah perlu dilakukan penambahan nutrisi pada tanaman namun dengan mahalnya harga pupuk perlu dicari alternatif lain. Untuk itu dilakukan penelitian pemanfaatan abu limbah penyulingan serai wangi menjadi pupuk organik untuk meningkatkan produktivitas kacang tanah. Penelitian ini dilakukan di Kebun Percobaan Balittro Laing Solok sejak September sampai Desember 2017. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan yaitu pemberian abu limbah penyulingan serai wangi dengan dosis : 1) 200 g 2) 250 g 3) 300 g dan 4) 0 g pada 8 tanaman per plot diulang 6 kali. Benih kacang tanah ditanam dalam kantong berukuran 45 x 60 cm yang berisi media tanah dan pupuk kandang dengan volume 1 kg/kantong. Variabel yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah polong, bobot basah, bobot kering serta bobot kering/100 biji. Pengamatan pertumbuhan dilakukan setiap dua minggu dimulai tiga minggu setelah tanam. Hasil penelitian menunjukan bahwa pertumbuhan vegetatif dan produksi tanaman kacang tanah mempunyai perbedaan yang signifikan dari setiap dosis abu limbah penyulingan yang digunakan. Dengan hasil yang terbaik pada dosis abu limbah serai wangi 300 g/kantong terlihat pada tinggi tanaman, jumlah cabang, jumlah polong, berat basah, berat kering dan berat per 100 biji berturut-turut 46,82 cm, 4,76 buah, 37,72 buah, 80,31 g, 35,40 g dan 62,36.","PeriodicalId":33922,"journal":{"name":"Journal of Applied Agricultural Science and Technology","volume":"68 4 Pt 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77449580","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 pengembangan lahan gambut untuk tanaman padi sawah terdapat beberapa faktor pembatas,diantaranya adalah kandungan asam fenolat yang tinggi sehingga dapat meracuni tanaman dan lemahnya ikatan kation K pada tanah gambut. Penelitian ini bertujuan untuk mengetahui distribusi K pada tanaman dan K tercuci akibat pencucian dan pemakaian zeolit serta kalium. Percobaan dilakukan dengan Rancangan Faktorial yaitu perlakuan zeolit (0, 5, 10 dan 15 g/kg), K (0, 125, 250 dan 375 mg K/kg) dan pencucian dengan tiga kali pengulangan. Semua perlakuan ditambahkan Fe3+ sebanyak 2,5% serapan maksimum Fe3+ dan diinkubasi sebulan sebelum ditanam. Tanah yang digunakan pada penelitian ini diambil dari tanah gambut pantai (Lagan) dan peralihan (Dendang) Jambi. Percobaan menggunakan pot yang berdiameter 25 cm dan tinggi 40 cm. Pada kedalaman 40 cm dilubangi dengan diameter 1 cm dan ditutup kembali (pencucian).Tiap pot ditanami 3 bibit padi IR-64 berumur 21 hari, ditambahkan 86Rb dan pemupukan dasar. Pencucian dilakukan dengan 1.000 ml air bebas ion setiap minggu sampai umur tanaman 4 minggu (panen), untuk menganalisa distribusi K pada tanaman. Pengaruh pencucian, pemberian zeolit dan kalium berpengaruh nyata terhadap 86Rb pada bagian tanaman dan 86Rb tercuci. Pemberian zeolit 15 g/kg dan K 375 mg K/kg dengan pencucian pada gambut pantai dan peralihan diperoleh 86Rb pada bagian atas tanaman : 4,792% ; 1,450% dan akar 0,490% ; 0,316%. Sedangkan tanpa pencucian pada gambut pantai dan peralihan, 86Rb pada bagian atas tanaman yaitu 1,599% ; 1,059 dan akar 0,253% ; 0,204%. Kehilangan K pada tanah gambut akan berkurang akibat pencucian dengan peningkatan takaran zeolit. Pada gambut pantai dengan pemberian zeolit 5-15 g/kg mampu mengurangi kehilangan K dari pupuk sebanyak 0,1-3,0%, sedangkan untuk gambut peralihan 0,04-2,2%.
