Abstract

Penelitian ini bertujuan untuk mengetahui mutu dari pupuk hayati Illetrisoy. Penelitian diawali dengan identifi kasi jenis mikrob penyusun pupuk hayati, kualitas bahan pembawa dan produk pupuk hayati. Hasil penelitian menunjukkan bahwa Illetrisoy A dan Illetrisoy B mengandung 4 jenis bakteri yang berasal dari genus Phaenibacillus dan Bacillus. Bahan pembawa Illetrisoy berupa campuran gambut dan serbuk arang memberikan mutu yang baik pada Illetrisoy A (pH 6,75, C 22,13%, N 1,32%, P2O5 389 ppm, K 2,68 me/100 g dan total populasi 36,5 × 108 cfu/g bahan) dan Illetrisoy B (pH 6,92, C 21,74%, N 1,25%, P2O5 412 ppm, K 2,47 me/100 g dan total populasi 34,9 × 108 cfu/g bahan). Aplikasi pupuk hayati Illetrisoy terhadap tanaman kedelai dilakukan di rumah kaca Balitkabi pada MH II 2012. Perlakuan pemberian pupuk hayati Illetrisoy A dan Illetrisoy B dengan atau tanpa pemberian pupuk kandang tidak menunjukkan perbedaan terhadap karakter morfologis maupun hasil biji, yang belum dapat mengungguli perlakuan NPK. Penggunaan Illetrisoy memberikan harapan untuk mengurangi masukan pupuk kimia dan memperbaiki sifat-sifat tanah secara berkesinambungan. Disarankan penelitian dilakukan dalam periode waktu yang lebih panjang dan terintegrasi dengan pola tanam dan sistem budi daya yang ada. This study aimed to determine the quality of bio fertilizer.

Abstract

Kenari (Serinus canaria) merupakan salah satu contoh burung anggota Passeriformes yang banyak diperdagangkan dan dipelihara karena keindahan bulu dan kicauannya, namun tidak semua burung kenari yang diperdagangkan memiliki kondisi fisik yang baik, kondisi tersebut dikarenakan adanya ektoparasit yang menyerang tubuh burung kenari tersebut. Bathing merupakan salah satu cara mengurangi ektoparasit pada burung. Penelitian ini bertujuan untuk mendeskripsikan pengaruh frekuensi bathing terhadap tingkat serangan ektoparasit pada burung kenari, pengaruh frekuensi bathing terhadap perilaku burung kenari dan menentukan frekuensi yang optimal untuk mengurangi tingkat serangan ektoparasit pada burung kenari. Penelitian ini dilakukan dengan rancangan acak lengkap dengan tiga perlakuan, yaitu bathing sehari sekali, dua hari sekali, dan tiga hari sekali. Sebanyak 9 burung kenari sebagai sampel diperoleh dari penangkaran dan belum memperoleh pengobatan. Kegiatan penelitian ini akan dilaksanakan selama tiga bulan. Data tingkat serangan ektoparasit, perilaku preening dan kicau burung dianalisis dengan uji Kruskall-Wallis dan Uji Wilcoxon. Hasil penelitian menunjukkan adanya penurunan tingkat serangan ektoparasit yaitu terdapat penurunan jumlah ektoparasit pada tubuh kenari di akhir perlakuan. Frekuensi bathing yang optimal untuk mengurangi tingkat serangan ektoparasit adalah frekuensi bathing sehari sekali, namun yang memberikan pengaruh terbaik untuk kicau burung adalah bathing dua hari sekali.Canary (Serinus canaria) is one of member of Order Passeriformes, which are frequestly traded because of the beauty of its feather and song. However, canary that are kept as pets are often found in unhealthy condition. For example infected by ectoparasites. Bathing is one of efforts that can be applied to reduce the infection level of ectoparasites. The purposes of this study were to describe the influence of bathing frequency on the infection level of ectoparasites and the preening and singing behaviour of birds; as well as define the best frequency of bathing. This research was done by using completely randomized design with three treatments, namely bathing every day, every two days, and every three days. Nine canaries obtained from captive breeding were used as sample. The treatment was conducted for three months. Data of infection level of ectoparasites, preening and singing behaviour were analysed by using Crustal-Wallis test and Wilcoxon test. The result showed that the infection level after treatment decrease significantly. The best treatment of bathing frequency to reduce the infection level of ectoparasites was one a day. However, the treatment that gave the best influence on the singing behavior was bathing every two days.

Abstract

Di daerah Bangkalan, masyarakat lokal banyak memanen kerang darah di perairan, terutama saat pantai surut. Karena perairan Bangkalan berada di dekat Surabaya, maka tidak menutup kemungkinan dalam tubuh kerang darah tersebut juga terkandung logam berat kadmium (Cd). Asam sitrat dikenal sebagai salah satu pereduksi logam berat. Senyawa ini banyak ditemui dalam bahan-bahan alami, misalnya asam jawa. Penelitian ini bertujuan untuk mengevaluasi kandungan logam berat kadmium (Cd) pada kerang darah (Anadara granosa) yang diambil dari perairan Bangkalan; menguji pengaruh larutan asam jawa untuk menurunkan kandungan logam berat kadmium (Cd) daging kerang darah yang diperoleh dari pantai-pantai di Bangkalan. Pengujian rancangan acak lengkap dengan empat perlakuan perendaman dalam larutan asam jawa, yaitu konsentrasi larutan 90%, 60%, 30%, dan 0% sebagai kontrol. Kadar logam berat daging kerang darah dianalisis secara deskriptif dengan membandingkan dengan SNI. Data penurunan kadar logam berat dianalisis dengan uji ANAVA satu arah untuk mengetahui pengaruh perendaman dengan larutan asam dan dilanjutkan dengan uji Duncan untuk menentukan konsentrasi yang optimal. Hasil penelitian menunjukkan bahwa kandungan logam berat kadmium pada kerang darah dari perairan Bangkalan adalah sebesar 0.035 ppm. Kadar ini masih di bawah ambang batas SNI sehingga aman dikonsumsi, namun bila terus-menerus berbahaya, oleh karena itu perlu diturunkan kadarnya. Larutan asam jawa dapat menurunkan kadar logam berat kadmium dengan persentase tertinggi pada perendaman konsentrasi 90% sedangkan persentase terendah terdapat pada perlakuan kontrol sebesar 0%. Hasil penelitian ini diharapkan dapat memberikan alternatif cara untuk menurunkan kandungan logam berat kadmium pada kerang darah dengan memanfaatkan bahan alami dan bernilai ekonomis. In the Bangkalan area, many local people harvest cockles from the coastal waters, especially during the low tides. Bangkalan coastal waters are located near Surabaya, there was possibility that the cockles also contained heavy metal cadmium (Cd). Citric acid is known as one of the reduction of heavy metals. This compound is found in many natural ingredients, such as tamarind. This study aimed to evaluate the content of cadmium (Cd) heavy metals in cockles (Anadara granosa) taken from Bangkalan coastal waters; tested the effect of tamarind solution to reduce the content of heavy metal cadmium (Cd) in the flesh of cockles obtained from the beaches of Bangkalan. This study used a completely randomized design with four soaking treatments in a tamarind solution, i.e. concentration of 90%, 60%, 30%, and 0% as a control. Heavy metal content of cockles flesh was analyzed descriptively by comparing with the maximum limit of SNI. Data on the reduction of heavy metal content were analyzed by one-way ANAVA test to determine the effect of soaking with acid solution and followed by Duncan test to determine the optimal concentration. The results showed that the content of cadmium in the flesh of cockles from Bangkalan waters was 0.035 ppm. This level is still below the SNI threshold so it is safe for consumption, but if it is constantly dangerous, it is necessary to reduce the levels. Tamarind solution can reduce the levels of heavy metal cadmium with the highest percentage at an immersion concentration of 90% while the lowest percentage is in the control treatment by 0%. The results of this study are expected to provide an alternative way to reduce the content of cadmium in the cockles by utilizing natural ingredients.

Abstract

Lahan kritis berkapur, karst, memberikan cekaman abiotik pada tanaman karena hambatan hidrasi dan nutrisi. Asam absisat (ABA) adalah hormon yang diekspresikan tumbuhan pada kondisi cekaman abiotik. CmBG1 merupakan salah satu gen peregulasi hormon ABA pada melon yang akan terakumulasi saat tumbuhan mengalami cekaman. Tujuan penelitian ini adalah mendeskripsikan pengaruh lahan kritis karst terhadap ekspresi gen CmBG1 secara kualitatif dan kuantitatif melon hasil turunan kultivar TACAPA, yaitu kultivar PT dan AT yang ditanam pada medium tanah karst dari wilayah Agroekosistem II dan III Yogyakarta (Gunungsewu, Dlingo, maupun Sentolo). cDNA library diperoleh dari reverse transcription isolat RNA. cDNA diamplifi kasi dengan primer spesifi k, kemudian dispektrofotometri pada ?260 nm untuk mengetahui konsentrasi gen CmBG1. Ekspresi gen dianalisis dengan real time PCR dengan gen referensi Cm-actin. Uji kualitatif dilakukan dengan elektroforesis gel agarosa 1,5%. Hasil penelitian menunjukkan gen CmBG1 terdeteksi dengan ukuran ±1258 bp pada kultivar PT dan AT. Konsentrasi gen CmBG1 melalui spektrofotometri menunjukkan semua kultivar yang ditanam pada media kontrol memiliki konsentrasi yang lebih rendah bila dibandingkan media tanam dengan perlakuan lahan kritis baik Gunungsewu, Dlingo, maupun Sentolo. Hasil ini sama dengan uji ekspresi gen CmBG1 menggunakan analisis kuantitatif real time PCR. Karsts critical land gives abiotic stresses in plants because of hydration and nutrition disturbances. Abscisic acid (ABA) is a hormone that expressed in the plant in abiotic stress conditions. CmBG1 is one of the regulatory genes encoding hormone ABA in melon plants which is accumulated in stress condition. The purpose of this study was to describe the infl uence of karsts critical land on the genes expression of CmBG1 melon cultivars PT and AT qualitatively and quantitatively. The plants were grown in medium karst land of Agroecosystems II and III of Yogyakarta (Gunungsewu, Dlingo, and Sentolo). Total RNA was extracted from leaf tissue then Reversed Transcriptase (RT-PCR) to collect cDNA library. cDNA was amplifi ed using specifi c primer. Spectrophotometry was conducted in ?260 nm and electrophoresis run in 1.5% agarose gel. Control band and reference gene chosen in Real Time PCR was Cm-Actin. CmBGI band (± 1258 bp) was showed both on PT and AT. Cm-actin was showed band of DNA as ± 445 bp. CmBGI gene concentration in critical land medium treatment which is given greater stress on melons are higher than normal condition. This suggests that the CmBGI gene is expressed more in cultivar PT and AT melons when they are grown under stress condition. This result show similarly when using real time PCR.
