Abstract

Herpetofauna communities are formed due to the suitability of the habitat or adaptation process that forces a species to survive. The opening of the land mines result in missing or changing the habitat of herpetofauna. This research was conducted to know the preferences of the herpetofauna of habitat based on spatial distribution of herpetofauna in the vicinity of mining area of PT Singlurus Pratama. The survey was conducted in the area of revegetasi, forest fragmentation, the district adjacent to the mining area, rivers and water spots or natural and man-made on two mining blocks i.e. block Pearl and block independence. The method of election of purposive sampling location with direct search survey methods (Visual Encounter Surveys). The main species found 4 that its spread most widely with populations high. The most frequent species of herpetofauna and many found among others: Eutropis multifasciata, Enhydris enhydris, Fejervarya cancrivora, Polypedates leucomystax and Duttaphrynus melanostictus. Based on the value of the index indicates that the diversity of herpetofauna communities distress with low. Types of herpetofauna more land cover found in the undergrowth, secondary forest and agricultural areas that there are sources of water in it.

Abstract

The research objective were to study the effect of compost fertilizer and Nasa liquid organic fertilizer (POC Nasa) and its interaction on the growth and yield of cucumber and also to find the proper dosage of compost fertilizer and POC Nasa concentration for obtaining the best growth and yield of cucumber.The research used Completely Randomized Design (CRD) in 4 x 4 Factorial Experiment and three replications.  The factor was the dosage of compost fertilizer (K) consisting of 4 levels : no compost fertilizer application (k0), 48 g polybag-1(k1), 64 g polybag-1 (k2); and 80g polybag-1(k3).   The second factor was the concentration of POC Nasa (D) consisting 4 levels : no POC Nasa application (d0), 1 ml l-1water (d1),  2 ml l-1water (d2), and 3 ml l-1water (d3).The results showed that: (1) the compost fertilizer treatment affected significantly on the weight of one fruit and the weight of fruit per plant, it affected very significantly on the plant lenght at age 15 and 30 days after planting, and fruit diameter, but it did not affect significantly on the number of fruit per plant.  The best production was produced at 48 g polybag-1 (k1) treatment of 3,77 kg plant-1, while the least one was produced at the 80 g polybag-1 (k3) treatment of 3,06 kg plant-1; (2)the POC Nasa treatment affected significantly on the weight of one fruit; and it affected very significanly on the plant lenght at age 30 days after planting and fruit diameter, but it did not affect significantly on the plant lenght at age 15 days after planting, number of fruit per plant, and fruit weight per plant;  and (3) the interaction treatment between compost fertilizer and POC Nasa affected significantly on the weight of one fruit and affected very significantly  on the fruit diameter, but did not affect significantly on the plant lenght at age 15 and 30 after planting, the number of fruit and fruit weight per plant.

Abstract

Remote sensing can be done visually and digitally. one of the advantages of airborne photography data generated by drone (phantom-3) compared to satellite imagery with optical sensitivity is its ability to obtain cloud-free images and freedom of recording time and the displayed area shows clearly defined objects corresponding to land cover. characteristics. To limit the object-based area of this research method applied is Object Based Image Analysis (OBIA).This study aims to classify land cover using highly resolved aerial photography with the help of Object Based Image Analysis (OBIA) technique and calculate the accuracy and accuracy, land cover classification by using Objeck Based Image (OBIA) analysis through examination of field conditions.classifying land cover, the classification includes shrubs, young shrubs, plantations (oil palms), shrubs, mines, open land, roads and water bodies with Accuracy of Overcome 0.86.

Abstract

Waaida Farm is a pioneer company of agribusiness of Physalis peruviana “ciplukan” in Indonesia. Waaida Farm started its cultivation of “ciplukan” with the considerations of “ciplukan” that has a big market opportunity. However, Waaida Farm could just fulfill the demand from Java so far because of its low production. The object of this research is to give a solution regarding the agribusiness developing strategy of “ciplukan” based on internal and external factors analysis which can be done at Waaida Farm. This research uses descriptive-qualitative design and study case research technique. Data collecting method used in this research is through interview and literature study. In needs to find the right developing strategy, there needs to be a matrix analysis of IFAS, EFAS, IE, SWOT and QSP. The SWOT analysis resulted five strategy formulations that can be implemented at Waaida Farm. The matrix QSP analysis resulted the right priority strategy for Waaida Farm, that is to invest the company’s profit for purchasing cooler boxes to overcome production shortages in certain periods and to increase the number of sales.

Abstract

Hasil Sensus Pertanian tahun 2003 dan 2013 menunjukkan jumlah rumah tangga pertanian pada tahun 2013 (22% dari total rumah tangga) di Kalimantan Timur  menurun dibandingkan tahun 2003 (34,85%). Penurunan jumlah rumah tangga pertanian dapat berdampak pada kuantitas dan kualitas produksi pertanian yang dihasilkan setiap kota/kabupaten. Tujuan studi ini adalah untuk mengetahui jumlah dan pertumbuhan Rumah Tangga Usaha Pertanian (RTUP) di Kalimantan Timur serta sebaran RTUP tahun 2003 dan 2013. Penelitian dilaksanakan pada bulan Maret – Juni 2017 di Kota Samarinda, Provinsi Kalimantan Timur, Indonesia. Data sekunder dikumpulkan dalam penelitian ini.  Analisis data menggunakan statistik deskriptif dan uji t. Hasil studi menunjukkan bahwa jumlah RTUP di Kalimantan Timur pada tahun 2003 dan 2013 berturut-turut adalah 203.179 rumah tangga dan 180.614 rumah tangga. Berarti terjadi pertumbuhan negatif jumlah RTUP di Kalimantan Timur sebesar -11,11% dalam kurun waktu 10 tahun tersebut dan rumah tangga pertanian tersebar tidak merata di seluruh kota/kabupaten di Kalimantan Timur.

Abstract

The purpose of this research is to know the effect of Tanijau organic fertilizer and organic fertilizer SMS Agrobost and its interaction with green eggplant growth and yield.The research method using Completely Randomized Design (RAL) in a 4x4 factorial experiment, with two treatment factors, was repeated as many as 4 repetitions. Factor I is the dose of Tanijau organic fertilizer (t), consisting of 4 levels, that is: without organic fertilizer Tanijau or control (t0), 2kg / polybag (t1), 4kg / polybag (t2), and 6kg / polybag (t3) . Factor II is the concentration of organic fertilizer SMS Agrobost (a), consisting of 4 levels, namely: without organic fertilizer SMS Agrobost or control (a0), 5ml / liter water (a1), 10ml / liter water (a2), and 15ml / liter of water (a3).The results showed that Tanijau organic fertilizer (t) was very different on plant height 15 days after planting, 30 days after planting, 45 days after flowering age, harvest age, weight per fruit, fruit weight per plant and the amount of fruit per plant is most achieved in the treatment of organic fertilizer Tanijau 6kg / polybag (t3) is1.519.56gr, while the least fruit cultivation is achieved at the treatment of t0 (without the dosage of Tanijau organic fertilizer) that is1.082,93gr.The effect of organic fertilizer SMS Agrobost differed significantly on plant height of planting age, flowering age, harvest age, number of fruits per plant, average weight per fruit, fruit weight per plant, fruit length per plant and fruit diameter per plant and number of fruit per plant. Treatment interaction was significantly different to fruit weight per plant, but was not significantly different from plant height 15, 30 and 45 days after planting.
