Kayu merupakan salah satu hasil hutan yang utama dan diperlukan oleh masyarakat guna memenuhi berbagai keperluan papan, diluar kebutuhan sandang dan pangan. Hasil pohon Albasia berupa penjualan kayu bulat semakin diminati petani, namun sedikit yang mengetahui nilai tambah untuk produk tersebut. Seiring dengan meningkatnya permintaan kayu, maka referensi mengenai karakteristik tanah di bawah vegetasi Albasia di Kecamatan Tegalwaru dapat memudahkan petani dalam praktik budidaya. Berdasarkan hal tersebut maka dilakukan penelitian deskriptif kuantitatif guna mengetahui karakteristik tanah, sekaligus melakukan analisis nilai tambah (metode studi kasus). Adapun karakteristik tanah diinventarisasikan berdasarkan Peta Jenis Tanah Indonesia skala 1:250.000. Sedangkan pada studi kasus nilai tambah, sampel dikategorikan dalam dua kelompok usaha berdasarkan penggunaan jumlah kapasitas mesin yang digunakan (total 11 responden). Tanah di bawah vegetasi Albasia pada Kecamatan Tegalwaru merupakan jenis tanah Ultisol, dengan karakteristik fisik berwarna merah, kemiringan ±12 %; penciri kimia seperti C-organik 2,2 %; pH (H2O) 5,43; KTK 28,3 c mol/kg; dan kandungan N-total 0,1 %. Hasil analisis menunjukkan bahwa nilai tambah yang diperoleh dari pengolahan kayu menjadi kayu olahan pada Industri Penggergajian Kayu (IPK) skala usaha kecil sebesar Rp. 108.730,30/m3 bahan baku, dengan rasio nilai tambah sebesar 19,56 %. Sedangkan nilai tambah pada IPK skala usaha besar adalah Rp. 119.897,60/m3 bahan baku, dengan rasio nilai tambah 16,30 %.

Abstrak. Tanah gambut memiliki sejumlah faktor pembatas dari sifat kimia tanahnya bila diupayakan untuk tanaman padi sawah. Beberapa faktor pembatas tersebut diantaranya yaitu pH tanah yang masam hingga sangat masam, kahat unsur mikro seperti Cu, dan rendahnya ketersediaan silika. Sedangkan tanaman padi memerlukan sejumlah unsur hara mikro dan lingkungan yang sesuai untuk tumbuh dan berproduksi. Kisaran nilai Cu dan silika tanah gambut diduga kahat atau tidak tersedia bagi tanaman padi sawah yaitu berturut-turut kurang dari 0,11 ppm Cu dan 54 ppm SiO2. Sedangkan kadarnya dalam tanaman untuk berproduksi dengan baik yaitu 1,11 ppm Cu dan 16,51 ppm SiO2. Ketika kadar silika dalam tanaman kurang dari 8,01 ppm, maka akan menghambat pertumbuhan tanaman padi dan produksinya. Abstract. Peat soil has limiting factors from soil chemistry when cultivated for paddy. This several limiting among acid to very acid soil pH, micro element like Cu was not available, and weak for silica availability. Whereas the paddy have need of micro nutrient and environment suitability for growth and production. The range of Cu nutrient and silica from peat soil, suspected was not available for paddy according to less than 0,11 ppm Cu and 54 ppm SiO2. While the nutrient content in plant (paddy) for good production has 1,11 ppm Cu and 16,51 ppm SiO2. When silica content in plant less than 8,01 ppm, that should be inhibit production and growth of paddy.

Agricultural cultivation activities can affect the distribution and population of soil fauna (Arthropods). They are was known as bioindicators of soil health and fertility. The addition of population, the reduction of diversity of certain of species, as well as the migration of a number of fauna can describe the condition of an environment. Based on this, the research was conducted on oil palm plantations that have various plant maintenance management treatments in order to optimize crop production. The research is located at PTPN VIII Cikasungka, Bogor Regency. The process of collecting soil fauna is carried out by sampling the soil, according to a predetermined transect line and putting it into the extractor (Kempson). The sampling time was carried out at the end of the dry season. The results showed that the average population of soil Arthropods was mostly found in the soil (1.050 individu/m2), while in litter the number was less (784 individu/m2). Where Acari and Collembola are the most Arthropods found both in litter and in the soil. Seeing the high population and biodiversity, that is still maintained despite the dry season, it can be said that the management carried out by PTPN VIII Cikasungka has prioritized the sustainability of the ecosystem within in.

APLIKASI KASCING DAN PUPUK KANDANG AYAM DALAM MEMPERBAIKI BAHAN ORGANIK TANAH SERTA PERTUMBUHAN KEDELAI Putro Hairutomo Setiko; Joko Santoso; Yudi Yusdian; Endang Kantikowati

The productivity of soybean nowadays is inversely related to the harvest area. The increasing area of ??soybean crops is not matched by production. Based on this, research was needed to increase soybean production, especially for soil types with low C/N ratio. The choice of this soil type is because soybeans are generally cultivated intensively. The current productivity of soybeans was low is one of which is thought to be due to a lack of organic matter and too fast nitrogen losses. The research was conducted in a demonstration plot (in a polybag in a plastic house) using a randomized complete block design, consisting of 7 treatments (A = control; B = 30 g vermicompost/polybag; C=60g vermicompost/polybag; D = 90 g vermicompost/polybag; E = 30 g poultry manure/polybag; F = 60 g poultry manure/polybag; G = 90 g poultry manure/polybag), with 4 repetitions. The results showed that the treatment of vermicompost and poultry manure significantly increased the growth and yield of soybean when compared to the control. A dose of 90 g poultry manure is recommended for applicated in farm because it can significantly increase soil C/N ratio, growth and yield of soybean.

This study aims to determine the effect of soil cultivation and nitrogen fertilizer dosage on the growth and yield of maize (Zea mays L.). This study used an experimental method with a Split Plot Design using 2 factors, namely soil cultivation (P) as the main plot consisting of 3 levels, namely p0 (without soil cultivation), p1 (minimum soil cultivation), p2 (perfect soil cultivation. ). The dose of nitrogen fertilizer (N) as subplots consists of 3 levels, namely n0 (0 kg ha-1 N), n1 (90 kg ha-1 N) and n2 (180 kg ha-1 N). The results showed: 1) there was an interaction between soil cultivation and nitrogen fertilizer dosage on plant height at 4 and 6 MST, and ear length, where complete soil treatment and nitrogen fertilizer dosage of 180 kg / ha (p2n2) gave the best results. 2) The effect of independent soil treatment and nitrogen fertilizer dosing on the observation of plant height at 5 WAP, and number of leaves at 4.5 and 6 WAP. The best results were found in p2 (Perfect Soil Treatment) and n2 (180 kg ha-1 N) treatments.
