This study aimed to determine the effect of biochar and Trichoderma harzianum toward lead removal in soil, lead absorption, lead content in plant tissue also growth and yield of shallot cultivated on lead-contaminated soil. The experimental design used was a completely factorial randomized block design consisting of 2 factors. The first factor was corn cobs biochar which was applied 1 week after basic fertilizer treatment and consisted of 4 levels, namely B0: without biochar, B1: 2.5 t ha-1, B2: 5 t ha-1, and B3: 10 t ha-1. The second factor was the dosage of liquid of Trichoderma harzianum, namely TR0: without T.harzianum, TR1: 10 mL L-1, and TR2: 20 mL L-1, which was applied three times at 14, 28 and 42 days after planting. Data were analyzed using the F test and continued with DMRT (Duncan Multiple Range Test) at P= 0.05 level. The results showed that the application of 5 t biochar ha-1 was able to remove lead and decreased lead uptake in plants. Application of T. harzianum could remove and decrease absorption in plant tissue biochar was not able to increase the growth of shallot while T. harzianum increased the number of leaves and the number of tubers.
Black rice is one of fungtional food sources. The obstacle of its cultivation is availability of qualified seeds and organic fertilizers input. This research aimed to determine the effect of stable manure on growth and yield of black rice, to observe the effect of seddling number per planting hole and to obtain the best combination of stable manure and seedling number on the growth and yield of black rice. The research was conduct in rice field on Karanglewas Kidul village, Karanglewas district, Banyumas, Central Java during April until September 2016. This research used a split plot design, with 3 repetition. The main plot was three type of stable manure (chiken, goat and cow), while the subplot was seddling number (1, 2 and 3). Data was analyzed using ANOVA and DMRT at <em>p</em> 0.05 level. The results showed that chicken manure gave the highest productivity rice of 5.15 tons ha<sup>-1</sup>. The 1 seedling each hole gave the highest result on panicle length and grain number per panicle. The better combination treatment was chicken manure and three seedling per planting hole wich gave the highest grain yield of 5.38 tons ha<sup>-1</sup>.
Peningkatan produksi padi lahan kering dapat dilakukan dengan sistem tumpang sari dan pemanfaatan asap cair tempurung kelapa. Penelitian ini bertujuan untuk mengetahui pengaruh tumpangsari padi gogo-rumput dengan aplikasi asap cair tempurung kelapa terhadap karakter pertumbuhan, fisiologis, dan hasil padi gogo serta tingkat serangan hama dan patogen pada kondisi kekeringan. Penelitian menggunakan rancangan petak petak terbagi dengan tiga ulangan. Petak utama terdiri atas varietas padi gogo; Situ Bagendit, Inpago Unsoed 1 dan Situ Patenggang. Anak petak merupakan konsentrasi asap cair tempurung kelapa yaitu tanpa aplikasi, konsentrasi 1:100 dan konsentrasi 1:200. Anak-anak petak terdiri atas tanpa rumput, rumput gajah, sereh dan rumput gajah+sereh. Variabel yang diamati meliputi tinggi tanaman, jumlah dan luas daun, jumlah anakan, kandungan prolin, kadar klorofil a dan b, jumlah gabah isi, bobot gabah petak efektif, bobot gabah ha-1, indeks panen, serta intensitas serangan hama dan patogen. Hasil menunjukkan bahwa padi gogo yang ditanam pada kondisi kekeringan dengan penanaman rumput dan aplikasi asap cair tempurung kelapa belum mampu menghasilkan produksi yang optimal. Tumpangsari padi gogo-sereh lebih memberikan dampak terhadap karakter pertumbuhan dan hasil padi gogo dibandingkan dengan aplikasi asap cair tempurung kelapa. Secara umum, hasil padi gogo < 1 t ha-1, namun varietas Situ Patenggang menunjukan hasil lebih baik dibandingkan varietas lainnya. Intensitas serangan walang sangit lebih rendah pada sistem tumpangsari padi gogo varietas Situ Patenggang-sereh. ABSTRACTRice production in the upland can be increased by multiple cropping system and coconut shell wood vinegar application. The objectives of this study was to know the effects of intercropped rice–grass with application of coconut shell wood vinegar on characters of growth, physiological, and yield of upland rice as well as intensity of pest and disease under drought condition. Split split plot design with main plot of upland rice varieties i.e. Situ Bagendit, Inpago Unsoed 1 and Situ Patenggang, sub plot consist of coconut shell wood vinegar concentration i.e. 0, 1:100 and 1:200, sub sub-plot of rice–grass intercropped i.e. no grass, Pennisetum purpureum, lemongrass and Pennisetum purpureum+lemongrass were tested with three replications. Observed variables were plant height, leaf number, leaf area, number of tillers, contents of proline, chlorophyll a and b, weight of grain in effective plot, weight of grain ha-1, harvest index and intensity of pest and disease. The results showed that rice-grass intercropped and application of coconut shell wood vinegar in drought condition has not been able to produce the optimal production. Under drought condition, intercropped rice-grass had significantly impact on the character of growth and yield of the upland rice. Generally, all upland rice varieties gained low yield (<1 t ha-1), but Situ Patenggang variety showed higher yield than other varieties and low intensity of brownhopper attack as well as in rice-lemongrass intercropped.
Objective of this study was to know the effect of NPK fertilizer and wood vinegar coconut shell on upland rice yield and, pest and disease intensity. Inpago Unsoed 1 was a main object in this study. Application of different dose of NPK as main plot viz. 50% and 100% recommended dose and concentration of wood vinegar coconut shell of ratio i.
Desa Wanadadi terletak berbatasan langsung dengan Waduk Mrica. Dampak dari pembangunan waduk adalah terjadinya pergeseran sosial masyarakat dari yang semula mata pencahariannya petani menjadi buruh, dan beternak. Masalah utama yang dihadapi peternak adalah ketersediaan pakan, sedangkan yang dihadapi pengelola Waduk Mrica adalah sedimentasi dan pertumbuhan eceng gondok. Eceng gondok merupakan gulma air yang dapat mengganggu kualitas perairan. Penanggulangan eceng gondok merupakan salah satu upaya dalam manajemen sumber daya dan lingkungan perairan untuk menjaga kelestarian oraganisme parairan. Disisi yang lain tanaman ini memiliki beberapa manfaat dan potensi yang layak untuk dikembangkan, yaitu sebagai bahan pakan ternak karena kandungan proteinnya cukup tinggi, sehingga dapat digunakan sebagai pengganti pakan pabrikan untuk ternak ruminansia maupun unggas. Kegiatan ini bertujuan untuk memanfaatkan eceng gondok menjadi usaha konservasi perairan waduk dan memberikan nilai tambah di masyarakat, yaitu meningkatkan ketrampilan masyarakat dalam pembuatan pakan ternak fermentasi guna mendukung usaha peternakan kambing. Metode yang digunakan dalam kegiatan pemberdayaan masyarakat ini adalah PRA (Partisipatory Rural Appraisal) yaitu peran serta aktif seluruh masyarakat yang terlibat dalam kegiatan ini. Meliputi kegiatan: penyuluhan dan pelatihan pemanfataan eceng gondok sebagai bahan silase pakan kambing, Pembuatan Demplot percobaan ternak kambing, pendampingan dan evaluasi. Diharapkan kegiatan ini dapat memberikan manfaat bagi masyarakat Desa Wanadadi.Kata Kunci: Budidaya Kambing; Eceng Gondok; Silase; Waduk Mrica.AbstractWanadadi Village is located directly adjacent to the Mrica Reservoir. The impact of the reservoir building is a social shift from the people whose livelihoods were originally farmers to become laborers, and livestock. The main problem faced by farmers is the availability of feed, while what is faced by the manager of the Mrica Reservoir is sedimentation and growth of weeds. Eichhornia crasippes is a water weed that can interfere with water quality. Eichhornia crasippes prevention is one of the efforts in the management of resources and the aquatic environment to maintain the sustainability of wter microoganism. On the other hand this plant has several benefits and potential to be developed, namely as animal feed ingredients because the protein content is quite high, so it can be used as a substitute for manufacturing feed for ruminants and poultry. This activity aims to utilize water hyacinth into conservation efforts of reservoir waters and provide added value in the community, namely improving community skills in the manufacture of fermented animal feed to support goat farming. The method used in this community empowerment activity is PRA (Partcipatory Rural Appraisal), namely the active participation of all communities involved in this activity. Includes activities: counseling and training on the use of water hyacinth as goat feed silage material, Making goat experimental demonstration plots, mentoring and evaluation. It is hoped that this activity can provide benefits for the people of Wanadadi VillageKeywords: Goat Livestock; Eichhornia Crasippe; Silase; Mrica Reservoir.
