Abstract

The farm is an important sector that affects economic growth. El-Nino and La-Nina climate anomalies have an impact on the farm such as drought. Actions to overcome the limiting factors on marginal land need to be done through technologies application on soil conservation and water management, balanced soil nutrient management and a better understanding of climate anomalies. Therefore, mitigation models development and anticipation of the effects of drought need to be carried out to provide an alternative technology. The research stages was biophysical conditions analysis, hydrological and geological data analysis, and formulation of drought mitigation technology. Based on the research, there is a drought potential that needs to be anticipated. Technology that could be applied are water reservoirs, dykes, infiltration canals, rorak, slot mulch, and reservoir. Soil and water conservation technology can increase groundwater. Method that have a significant impact is making embankments with mulch, which can increase the soil water content up to 56%. Keywords: Drought, Farm, Groundwater, Trenggalek

Abstract

Air temperature is an important microclimate parameter in a greenhouse as it influences root growth and controls plant growth and development. Thus, the precise monitor and model temperature under greenhouse is needed to maintain the plants in optimal conditions. This research aims to model the temperature under a greenhouse using energy balance model. The study monitored the temperature inside and outside the greenhouse in a humid tropical environment. Based on the data, heat exchange constants of greenhouse components were derived, they were: 0.0029 (solar radiation), 0.8 (air) and 0.01 (heat exchange from greenhouse component). The calibrated model enables the calculation of temperature inside a greenhouse based on its outside air temperature, wind speed, and solar radiation. Testing the model against an independent time series showed the high accuracy of the model with an R2 value of 0.99, RMSE = 0.0085 and model efficiency Ef = 0.99. Based on the results, most advantageous strategies for air temperature control inside the greenhouse include the control of air ventilation.

Abstract

A Greenhouse has a different microclimate compared to the outside field. Climate parameters such as solar radiation and air temperature are important parameters that affect plant growth and productivity. This research aims to understand the relation of climate factors in the inside and outside Greenhouse, the effect of microclimate on evapotranspiration and to predict the amount og evapotranspiration inside the Greenhouse. Microclimate analysis was held in two stages, the firststage was from February 5 to March 21, 2018 and the second stage from March 19 to April 29, 2019 at the Department of Civil and Environmental Engineering, IPB University. Primary data was measured by the Decagon sensor. Solar radiation was collected using the Decagon PYR Pyranometer sensor and air temperature using the Decagon VP-4 sensor. Based on the result, the daily air temperature inside the Greenhouse was higher than that of the outside. The inside solar radiation was lower than that of outside the Greenhouse. The relative humidity fluctuated, and the air pressure was higher inside the Greenhouse. Evapotranspiration inside the Greenhouse was lower than outside and solar radiation was the most determining factor of evapotranspiration.

Abstract

Intrusion of sea water is the infiltration of sea water into the soil. This might be caused by a groundwater excessive exploration. Tangerang District is one of the areas that have great potential sea water intrusion. The aim of research was to predict the limit of salt water intrusion based on the value of DHL and TDS. The primary data were measured using a TOA EC meter CM-14P and then were processed using Surfer 9.0 software and ArcGIS. The measurement results was compared with PAHIAA Decision (1986) and Carroll’s Classification (1962). The results showed that the intrusion area could be identified by DHL and TDS values. On the area located far from the beach, intrusion was influenced by the presence of a river in the region. This was indicated by the regression analysis that showed a correlation between distance and value DHL/TDS with a negative slope value. Based on DHL and TDS parameters in observation area, the groundwater conditions in  Tangerang District within a radius of 0.095 km to 5 km from the littoral areas are categorized as medium intrusion zone (slightly brackish water) with DHL 1500-1999 μmhos/cm and TDS values 1000-3000 mg/LU.

Abstract

Manusia sangat menentukan tindakan kelestarian lingkungan terutama pada tanah dan air.  Manusia sebagai pengguna pada tanah untuk berbagai macam keperluan, terutama sebagai pemukiman dan usaha. Guna menjaga kelestarian pada tanah maka diperlukan pengelolaan tanah yang juga mengikutsertakan tindakan konservasi di dalam kegiatan pengelolaan dan pemanfaatan tanah.  Sebelum dapat menentukan tindakan konservasi untuk kelestarian tanah, maka diperlukan analisa erosi yang dapat diaplikasikan sebagai media untuk menentukan besarnya erosi pada suatu lahan.  Metode USLE (Universal Soil Loss Equation) adalah metode yang dapat diaplikasikan pada wilayah Indonesia sampai sekarang. Perkembangan intensifikasi lahan perkebunan terutama tanaman sawit sangat mempengaruhi kelestarian lingkungan.  Sehingga diperlukan tindakan penanggulangan dini dengan menganalisa erosi dari lahan perkebunan sawit dengan menggunakan metode USLE.

Abstract

Vinase merupakan hasil samping akhir dari proses pengolahan bioetanol yang berbentuk cair. Di Indonesia, produksi bioetanol masih mengandalkan molases tebu (Saccharum officinarum L.) sebagai bahan baku. Vinase berpotensi mencemari lingkungan, namun di sisi lain juga mengandung bahan organik, potasium, nitrogen, fosfor, dan berbagai unsur hara lainnya yang bermanfaat untuk pertumbuhan tanaman. Studi ini bertujuan untuk mengulas potensi pemanfaatan vinase sebagai produk samping produksi bioetanol berbasis tebu untuk pemupukan sekaligus irigasi (fertigasi) di perkebunan tebu di Indonesia. Metode yang digunakan adalah kajian literatur. Fertigasi dengan menggunakan vinase di lahan tebu dapat memberikan dampak positif terhadap sifat fisika, kimia, dan biologi tanah serta pertumbuhan tebu. Vinase bahkan berpotensi menjadi bahan substitusi pupuk potasium anorganik.

Abstract

Organic vegetables grown special in planthouses require  special irrigation practice to maintain  the optimum range of soil water content throughout the cultivation season. The problem of irrigation is the absence of parameter that used to determine schedule and water irrigation. This research was to figure out whether the sprinkle irrigation used for Kailan vegetable in a planthouse could fulfil the water demand and the total water consumption based on change of water content. Herewith, the daily soil moisture was observed and analyzed the water flow in the soil based on the soil physical and hydraulic properties. The result showed that the soil water content  was always within field capacity and permanent wilting point but 87% of cultivation period was lower than readily avaiable water (RAW). This condition indicated that the water irrigation is not optimal. Based on change of soil water content analysis, water consumption for kailan was 55  mm during cultivation with  the consumption rate was 1.1 mm/day. The water requirement to attain RAW condition was 130 mm.

Abstract

Desa Tempursari merupakan salah satu desa di Kecamatan Donomulyo yang memiliki intensitas curah hujan cukup tinggi dengan mayoritas penduduknya berprofesi sebagai petani dan peternak. Akan tetapi, pada musim kemarau Desa Tempursari tergolong daerah cukup gersang sehingga menimbulkan permasalahan yakni  berkurangnya ketersediaan rumput untuk pakan ternak dan kambing. Hal ini mengakibatkan peternak kesulitan untuk mendapatkan pakan ternak yang baik. Permasalahan ini akan berdampak buruk pada pertumbuhan dan perkembangan hewan ternak karena kurangnya asupan pakan yang baik. Permasalahan tersebut perlu segera diatasi agar para peternak tidak mengalami kesulitan dalam mendapatkan pakan ternak pada musim kemarau dan hewan ternak tetap mendapatkan asupan yang baik. Salah satu solusi untuk mengatasi permasalahan ini adalah dengan pengembangan pusat pakan ternak kambing fermentasi organik di Desa Tempursari. Metode yang digunakan dalam pelaksanaan ini adalah persiapan yang berupa survei dan analisa kebutuhan, pelaksanaan berupa pembuatan formula pakan fermentasi dan pendampingan pelatihan peningkatan mutu pangan, serta evaluasi dan laporan kegiatan. Hasil kegiatan ini berupa mesin pengolah pakan ternak fermentasi serta modul tentang pembuatan formula pakan organik fermentasi, strategi promosi, pengurusan izin edar, dan branding hasil pengolahan pakan organik.
