Abstract

Semut rangrang (Oecophylla smaragdina) telah diidentifikasi sebagai agen biokontrol pada berbagai jenis tanaman. Penurunan populasi dari tahun 2009-2012 sangat tajam, yakni berkisar 50% dari jumlah semula. Populasi semut rangrang pada tahun 1999-2006 cukup melimpah sehingga banyak tanaman hias maupun tanaman pangan dapat terselamatkan dari hama. Salah satu faktor penyababnya adalah perburuan telur atau larva (kroto) semut rangrang tanpa memperhatikan keseimbangan ekosistem. Hasil kroto yang ada di pasaran berasal dari alam, sedangkan alam tidak setiap saat menyediakan kroto. Disisi lain permintaan kroto terusmeningkat, maka budidaya semut rangrang menjadi sangat penting untuk memenuhi permintaan kroto yang tinggi dan pelestarian habitat baik unsur abiotik maupun biotik mempengaruhi kelimpahan semut rangrang di alam. Produksi kroto semut rangrang hasil budidaya pada dasarnya saat ini belum menjawab kebutuhan pasar yang ada. Kebutuhan akan kroto masih sangat jauh terpenuhi karena metode dan sistem para peternak masih banyak yang menggunakan cara yang belum tepat. Dampaknya adalah produksi kroto tidak maksimal. Penelitian ini dilakukan di Grendeng, Purwokerto Utara, Banyumas selama bulan februari sampai maret 2014. Tujuan dari penelitian ini untuk mengetahui pengaruh pemberian pakan sumber protein berbeda terhadap produksi kroto semut rangrang yang dibudidaya dan mengetahui jenis pakan sumber protein yang menghasilkan tingkat produksi kroto semut rangrang tertinggi yang dibudidaya. Penelitian dilakukan menggunakan metode eksperimental dengan rancangan acak lengkap (RAL). Perlakuan terdiri atas pakan sumber protein ulat hongkong (Tenebrio molitor), jangkrik (Gryllus assimilis), dan ulat kandang (Alphitobius diaperinus) masingmasing sebanyak 2 g dan setiap perlakuan diulang sebanyak 5 kali selama 25 hari. Hasil analisis ragam (ANOVA) menunjukkan bahwa pakan sumber protein berbeda (Tenebrio molitor, Gryllus assimilis, Alphitobius diaperinus) tidak berpengaruh nyata terhadap produksi kroto semut rangrang yang dibudidaya. Tingkat produksi kroto semut rangrang yang dibudidaya dengan pemberian pakan sumber protein ulat hongkong sebesar 50,98 g (3.568 individu), jangkrik sebesar 51,25 g (3.587 individu), dan ulat kandang sebesar 45,11 g (3.157 individu).

Abstract

The distribution of leachate and the pattern of fluid flow in Tempat Pembuangan Akhir (TPA) Putri Cempo were mapped by utilizing the Self Potential method. Data acquisition was done before and after the rain with a fixed base techniques with 10 meters interval distance with total number of observations were 78 points for data acquisition. SP Data were processed using Surfer 11 software to generate the isopotential contours. It is found that the leachate distribution anomaly is indicated only for after the rain observation. Interpretation was done by Rao and Ram Babu Theory. The result of vertical spreading of anomalous 1 was found at the depth of the upper end (h) 5.45 meters, the depth of the lower end (H) 17.62 meters and the angle of anomaly (θ) 840 while the anomalous 2 was found at the depth of the upper end (h) 5.45 meters, the depth of the lower end (H) 11.22 meters and the angle of anomaly (θ) 73.70. At the time before the rain, the pattern of fluid flow leading to the eastern part of the research area, while after the rain, the fluid flow coming from two directions, from the west and from the east of the research area leading to the central part of the research area.

Abstract

Identification of aquifer layer location has been done using Schlumberger configuration of geoelectric resistivity methods in Masaran District. Data collection was performed using resistivity meter OYO Mc-el-ohm series 2119c having a length of current electrode (AB / 2) from 1.5 m to 350 meters. Data processing was done using software IP2win. The purpose of this study was to identify the location of confined aquifer and unconfined aquifer. The result showed that litology of aquifer layers were detected as clayed sand, sands and gravel sands. The depth of confined aquifer was detected for TS1 (4.52 meters to 8.57 meters and 22.4 meters to 34 meters), TS2 (8.84 meters to 20.9 meters), TS3 (2.87 meters to 10 meters and 13.3 meters to 41.5 meters), TS4 (20.09 meters to 6.71 meters and 17.3 meters to 36.4 meters) and TS5 (6.3 meters to 25 meters). The thickest layer of confined aquifer was TS3. While, the depth of unconfined aquifer was detected for TS1 (68.1 meters to 78 meters and 94.3 meters to 115 meters), TS2 (36.9 meters to 93.4 meters and 103 meters to 134 meters), TS3 (72.8 meters to 101 meters), TS4 (46.3 meters to 67.5 meters and 82.1 meters to 98 meters), and TS5 (50.1 meters to 93.5 meters and 99.7 meters to 111 meters). The layer thickness of unconfined aquifer were detected for TS1 (30.6 meters), TS2 (86.7 meters), TS3 (28.4 meters), TS4 (37 meters), and TS5 (55 meters). The layer thickness of unconfined aquifer that has the thickest was TS2.
