Abstract

The objectives of this study was to determined the concentration of gelatin that of the best in the production of jelly candy from sugar apple juice were physical, chemical and organoleptic characteristics. This study used completely randomized design with using sugar apple juice concentration as treatment consists of 4 degree i.e.6, 8, 10 and 12% (w/w). The organoleptic test using a randomized block design classification was based on each panelist, then the number of them panelist were involved 15 people. each treatment was repeated two times, so that would be obtained 8 samples. The treatment is significant in a further test with honestly significant difference test level of 5%.The results showed that the physical quality of the gelatine concentrations differences to have total soluble solid. The highest content of it made from gelatine 8% that is 1,94%, the solubility 12% (7.70%) and the water holding capacity at the 6% (2.82%), oil holding capacity at the 6% (2.15%), chemical quality such as water content at the8% (62.46%), vitamin C 6% (33.00% ) and dietary fiber at the 12%(7.46%). While the best of organoleptic test concentrations of gelatine at the 8% i.e the texture 4.20, colours 5.40, flavour 4.27, taste 4.27 and alike of comprehenship 4.80 which the were included neutral.

Abstract

Along with the discovery of several gold prospects area in ??Central Sulawesi, gold mining had increased both by companies, cooperatives and illegal mining. The activity of this mining produce waste that consist of hazardous toxic substances in which there was a heavy metal such as mercury (Hg). This metal is one of the trace elements that has liquid at room temperature, high specific gravity and power electric conductivity, and a toxic chemical element became a global concern because has significant hazardous effect on human health, wildlife and ecosystems. This study was  aims to know the content of mercury in soil around the Poboya?s gold mining. The method used in this study was a survey which describes the actually condition of this area and assess the causes of certain symptoms. In this study measurements, field observations, and laboratory analysis had been done. There step that be noticed in this survey were pre-survey, main survey (sampling) and laboratory analysis. Compose soil sample for laboratory analysis had been collected from several sample point that had been plotting by tactics. The results of this study showed that the content of mercury in all representative soil sample and tailings had highest than threshold. Normally, concentrations of mercury in the soil range from 0.03 ppm (normal) to 0.3 to 0.5 ppm (critics); while concentrations of mercury in soil agricultural areas ranged from 0.057 ppm to 8.19 ppm and in tailings ranged from 84.15 ppm - 575, 16 ppm.

Abstract

Sebagian wilayah Kabupaten Donggala, Provinsi Sulawesi Tengah merupakan sentra produksi bawang. Terdapat dua masalah utama yang menghambat pengembangan bawang di Lembah Palu, yaitu curah hujan tahunan rendah dan kedalaman efektif yang dangkal.  Kondisi tersebut menyebabkan terbatasnya penyediaan air untuk dapat memenuhi pertumbuhan tanaman semusim, terutama bawang merah varietas lokal yang banyak dibudidayakan oleh masyarakat di desa Guntarano Kabupaten Donggala.  Penelitian ini bertujuan untuk mengetahui pengaruh irigasi penggenangan dan pelumpuran terhadap laju evapotranspirasi tanaman Bawang Merah Varietas Lembah Palu dan beberapa sifat fisika tanah pada Entisol Guntarano. Penelitian rumah kaca dengan menggunakan rancangan acak lengkap dilakukan di Laboratorium Ilmu tanah Fakultas Pertanian, Universitas Tadulako, Palu. Pelaksanaan penelitian dimulai dari bulan Maret 2012 sampai September 2012.    penelitian terdiri dari 2 faktor, yaitu interval irigasi dan pelumpuran.  perlakuan interval irigasi terdiri dari 3 level, yaitu:  interval irigasi 2 harian (w1), 4 harian (W2), dan 6 harian (W3).  Perlakuan pelumpuran terdiri dari 3 level, yaitu tanpa pelumpuran (P0), pelumpuran 1 kali (P1) dan pelumpuran 2 kali (P2).  Hasil penelitian menunjukkan bahwa terdapat interaksi diantara perlakuan interval irigasi dan pelumpuran terhadap laju evapotranspirasi, bobot isi tanah, porositas total, dan konduktivitas hidraulik tanah jenuh.  Laju evapotranspirasi tanah tertinggi terdapat pada perlakuan W2P1.  Bobot isi tanah tertinggi terdapat pada perlakuak W3P2.  Porositas total dan konduktivitas hidraulik tanah jenuh menunjukkan nilai tertinggi pada perlakuan-perlakuan W1P0.

Abstract

Penelitian ini bertujuan untuk menginventarisasi jenis-jenis predator hama Helopeltis spp. pada tanaman kakao (Theobroma cacao). Penelitian ini dilaksanakan pada bulan Februari hingga April 2013, pada perkebunan kakao rakyat di Desa Sejahtera Kecamatan Palolo Kabupaten Sigi. Metode penilitian dilakukan dengan survei dan dua cara yakni, dilakukan secara langsung di lokasi survei, dengan mengamati predator yang ditemukan sedang memangsa hama Helopeltis spp., pengamatan dilakukan terhadap perilaku dan kemampuan dalam menanggapi mangsanya, dan juga secara sengaja diberikan mangsanya pada jaring jenis laba-laba. Pengamatan selanjutnya dilakukan dengan menggumpulkan predator dari lokasi penelitian dengan menggunakan plastik bening dan kuas. Sampel yang terkumpul dibawa ke Laboratorium Untad untuk dilakukan pengamatan perilaku dan kemampuan dalam menanggapi mangsanya dan selanjutnya predator tersebut diidentifikasi berdasarkan ciri morfologinya dengan menggunakan mikroskop binokuler. Hasil penelitian menunjukkan bahwa selama pengamatan berlangsung (4kali pengamatan), didapatkan 5 spesies predator hama Helopeltis spp. pada pertanaman kakao, yakni Oecophylla smaragdina, Gastercantha spp., Leucauge venusta, Cycloneda spp., dan Forticula auricularia. Dari kelima spesies tersebut yang paling berpotensi dalam menangani mangsanya yakni Oecophylla smaragdina dan disusul spesies predator lainnya. Kelima spesies predator tersebut memiliki perilaku dan kemampuan yang berbeda dalam menanggapi mangsanya.
