Abstract

Serai wangi memiliki nilai ekonomi sangat tinggi dan dapat dibudidayakan pada berbagai kondisi lahan. Lahan marginal umumnya kurang subur, kecuali setelah direhabilitasi melalui pengelolaan irigasi tepat dan pemupukan berimbang. Integrasi parameter kualitas lahan/tanah marginal yang direhabilitasi terhadap paremeter produktivitas serai wangi, yang sejauh ini belum banyak dikaji, mutlak diperlukan. Penelitian ini bertujuan untuk mengidentifikasi pengaruh variasi jadwal irigasi dan dosis pupuk organik terhadap sifat fisik tanah dan pertumbuhan serai wangi. Sebanyak 9 demplot serai wangi (luas: @9 m2, jenis tanah: Inceptisol) disiapkan untuk 2 taraf perlakuan, yaitu variasi jadwal irigasi [per hari (SI1), per 3 hari (S13), per 5 hari (SI5)] dan variasi dosis pupuk organik [15 ton/ha (PO1), 25 ton/ha (PO2), 35 ton/ha (PO3)]. Variabel yang diamati meliputi pertumbuhan serai wangi [jumlah batang (JB), tinggi tanaman (TT), jumlah daun (JD)], sifat fisik tanah [kadar air basis Volume (θ), kerapatan isi (rb), permeabilitas (Ks)], serta debit irigasi dan curah hujan. Data pengamatan dianalisis secara statistik (ANOVA, α = 0.05) dan ditampikan secara grafis. Hasil penelitian menunjukkan bahwa jadwal irigasi dan dosis pupuk organik berpengaruh nyata terhadap JB, TT, dan JD serai wangi dengan nilai optimal masing-masing terdapat pada SI3PO3 (20.17 batang), SI1PO3 (137.83 cm), dan SI3PO3 (92.25 helai). Dilihat dari sifat fisik tanah, hanya dosis pupuk organik yang berpengaruh nyata, terutama terhadap θ, dengan nilai optimal terdapat pada PO2 (0.380 cm3/cm3). Kombinasi jadwal irigasi per-3-hari (SI3) dan dosis pupuk organik 35 ton/ha (PO3) sangat potensial untuk diaplikasikan pada budidaya serai wangi di lahan marginal.

Abstract

The objective of this study was to determine the best tillage method for making planting beds forvegetables cultivation using a two-wheel type tractor. Five tillage methods using a two-wheel type tractorwith its equipments were tested and evaluated in this study. The methods which were tested were: 1)plowing using a reversible type plow, followed by ridging using a ridger and finished by harrowing using arotary tiller (B-F-G 1 method) ; 2) plowing, followed by harrowing and finished by ridging (B-G-F method);3) plowing, followed by harrowing followed by ridging and finished by 2nd harrowing (B-G-F-G method); 4)plowing, followed by 40 cm width of harrowing and finished by ridging (B-G-F 2 method); and 5) plowing,followed by 40 cm width of harrowing and finished by ridging with 40 cm tractor wheel-base (B-G-F 3method). The experiments were conducted on several plots of dry land. The results of the experimentsshowed that the B-G-F 3 method produced the best planting bed form, an appropriate bed size and abetter soil condition for vegetables cultivation. The field capacity of this method was 74 m2/hour and wasthe highest capacity among the five methods.Keywords: planting bed, two wheel tractor, tillage, vegetable cultivationDiterima: 9 Desember 2008; Disetujui: 20 Maret 2009

Abstract

Previously, horizontal-ridge system has been shown effective in reducing soil erosion. But, it could cause water logging, which is detrimental to crop growth and yield. To solve this problem, drainage canal establishment might be reasonable. However, the evidence remains scarce. In this study, effect of drainage canal intervals on the volume of runoff, soil loss, and nutrient loss (N-total and P-total) were investigated. There were 4 drainage canal intervals applied to the 12 targeted plots (each sized 3 m x 3 m): R0, R1, R1.5, and R2 namely 0 m, 1 m, 1.5 m, and 2 m, respectively. In this case, R0 had no drainage canals and taken as the control. The measured runoff, soil loss, N-total loss, and P-total loss ranged 24.714 – 0.951 m3 ha-1, 0.002 – 0.507 ton ha-1, 0.849 – 204.881 kg ha-1, and 0.685 – 176.505 kg ha-1, respectively. The results revealed that existence of drainage canal increased runoff, soil loss, and nutrient loss compared to the control. Amongst them, R1 gave the highest values of soil and nutrient losses followed by R1.5, R2, and R0 as the lowest, which was probably due to the difference in number of drainage canal existing: 12, 7, 5, and 0, respectively. In addition, it was noticeable for a sufficient data trend conformity of the measured nutrient loss to the data of soil loss, runoff, and rainfall within a positive correlation amongst them. The data further confirmed the effect of soil structure condition on the volume changes of both runoff and soil loss.

Abstract

Precise and measurable water availability is an important aspect for optimal plant growth. It is necessary to monitor soil moisture continuously as a basis for watering. This paper presents the design of a soil moisture measurement system and testing of a capacitive type soil moisture sensor to obtain a calibration model on various types of soil. The measurement system is based on an Arduino-Mega microcontroller consisting of a soil moisture sensor, timer module, memory card module, keypad, LCD and irrigation actuator. In this research, five capacitive soil moisture sensors were tested on three types of soil, namely sand soil, and organic soil. Sand soil comes from the coast in Adipala Village, Cilacap Regency and organic soil comes from dry land in Kedungrandu Village, Banyumas Regency. The calibration process is based on the capacitive soil moisture sensor voltage (V) and soil water content (KA) values determined using the gravimetric method. The calibration model obtained for each soil is KA = 34.23 x V2 -182.84 x V + 249.45 (sandy soil), and KA = 2389 x V2 - 9252.6 x V + 9012.9 (organic soil). Soil moisture outputs, time data, and irrigation status are stored in the memory card.

Abstract

Dalam penelitian ini dilakukan pengujian terhadap sensor gas MOS tipe MQ (MQ-2.1, MQ-2.2, MQ-3, MQ-4, MQ-5, MQ-6 MQ-7, MQ-8, MQ-9, dan MQ-135) untuk mendeteksi kemurnian minyak nilam. Penelitian ini dilakukan dengan tujuan: 1) mempelajari respons sensor gas MOS tipe MQ dalam mengidentifikasi kemurnian minyak nilam, dan 2) mempelajari akurasi sensor gas MOS tipe MQ dalam mengidentifikasi kemurnian minyak nilam. Minyak nilam yang digunakan adalah minyak nilam pada berbagai tingkat pencampuran dengan minyak zaitun. Terdapat 2 jenis perlakuan yang diamati, yaitu: dengan pemanasan dan tanpa pemanasan. Pengukuran dilakukan terhadap nilai Baseline measurement (Ro) dan Atsiri measurement (Rg) guna menentukan nilai sensitivitas sensor (S). Selanjutnya nilai Rg dan S digunakan untuk membuat grafik loading plot berdasarakan metode PCA (Principal Component Analysis) untuk menentukan respon individu setiap sensor. Tingkat akurasi sensor dalam mendeteksi minyak nilam ditentukan berdasarkan: identifikasi minyak nilam menggunakan grafik score plot, klasifikasi data menggunakan metode COG (Center of Gravity) dan ED (Euclidean Distance), serta penghitungan akurasi. Dari kesepuluh sensor gas yang diujikan, terdapat 2 sensor yang memberikan respon rendah yaitu MQ-3 dan MQ-7. Sedangkan 8 sensor yang lain memberikan respon yang baik dan relatif stabil, dengan respon tertinggi diperoleh dari sensor MQ-4. Rerata tingkat akurasi sensor yang dihasilkan pada nilai resistensi (Rg) lebih tinggi dibandingkan nilai sensitivitas (S), dan lebih tinggi pada perlakuan tanpa pemanasan dibandingkan perlakuan dengan pemanasan. Pada perlakuan tanpa pemanasan nilai rerata akurasi Rg dan S masing-masing adalah 88.79% dan 79.51%, sedangkan pada perlakuan dengan pemanasan masing-masing adalah 80.84% dan 74.52%.

Abstract

Tekanan angin roda traktor roda dua dapat mempengaruhi pemadatan tanah yang berdampak negatif terhadap sifat fisik tanah. Namun demikian, penelitian sebelumnya lebih berfokus pada kedalaman tanah < 25 cm, meskipun dampak pemadatan berpotensi mencapai kedalaman > 25 cm. Penelitian ini bertujuan untuk mempelajari pengaruh tekanan angin roda traktor roda dua terhadap dampak pemadatan tanah pada kedalaman 0 – 50 cm. Terdapat 4 taraf perlakuan tekanan angin roda traktor: tanpa perlintasan traktor (T0) sebagai kontrol, 7 psi (T7), 10 psi (T10), dan 12 psi (T12). Sampel tanah tidak terganggu diambil pada kedalaman 0 – 10, 10 – 20, 20 – 30, 30 – 40, dan 40 – 50 cm menggunakan standard soil ring sampler dengan jumlah ulangan 5 kali untuk setiap kedalaman (total 100 sampel). Sifat fisik tanah yang diukur adalah konduktivitas hidrolik jenuh (ks), dry bulk density (
