The Effectiveness of Experimental Diet with Varying Levels of Papain on The Growth Performance, Survival Rate and Feed Utilization of Keureling Fish (Tor tambra)
Full text linkThe objective of present study was to determine the optimum level of papain in the diet of keureling fish (Tor tambra). The complete random design was utilized in this study. Six levels of papain dosage were tested in triplicates, i.e. 0 (control); 17.5 mg kg-1, 20.0 mg kg-1, 22.5 mg kg-1, 25.0 mg kg-1 and 27.5 mg kg-1 of feed. The experimental fish were fed the experimental diet two times a day at 8 AM and 5 PM at feeding level of 5% body weight for 90 days. The Anova test result showed that papain enzyme gave a significant effect on the weight gain, daily growth rate, specific growth rate, survival rate, feed conversion ratio and feed efficiency (P<0.05). The Duncan multi-rage test result showed that the higher values for all measured parameters were obtained at the dosage of 27.5 mg kg-1. Therefore, it is concluded that the optimum dosage of papain enzyme for keureling fish was 27.5 mg kg-1 of feed.How to CiteMuchlisin, Z. A., Afrido, F., Murda, T., Fadli, N., Muhammadar, A.

PENGARUH DOSIS PUPUK KANDANG SAPI TERHADAP PERTUMBUHAN DAN HASIL TANAMAN GANDUM (Triticum aestivum L.) DI KECAMATAN GUNUNG TALANG KABUPATEN SOLOK
Full text linkPENDAHULUAN
Dewasa ini, tanaman gandum (Triticum aestivum L.) sedang menjadi salah
satu perhatian khusus bagi beberapa Negara di dunia, termasuk Indonesia. Di
Indonesia kebutuhan akan gandum semakin hari semakin meningkat. Contohnya
dalam penggunaan tepung terigu yang berbahan dasar dari gandum. Tepung terigu
merupakan bahan makanan penting kedua setelah beras. Kebutuhannya terus
meningkat dari tahun ke tahun. Makanan populer Indonesia yang berbahan baku
tepung terigu seperti mie, bakso, roti, martabak, bermacam jenis kue dan
sebagainya hampir dapat dijumpai di semua lapisan masyarakat. Pada umumnya
masyarakat Indonesia sudah mengenal dengan baik tepung terigu, namun hanya
sedikit orang yang mengetahui tanaman gandum, yaitu tanaman yang
menghasilkan biji gandum untuk bahan baku pembuatan tepung terigu. Gandum
sangat bermanfaat bagi kesehatan tubuh manusia karena kaya akan gizi.
Rimbawan (2004) menyatakan bahwa gandum memiliki kandungan nutrisi tinggi
seperti karbohidrat, serat pangan, protein, vitamin B1, B2, B3, B6, dan asam folat.
Kebutuhan akan gandum yang cukup tinggi belum seimbang dengan
ketersediaannya di Indonesia. Volume impor biji gandum diprediksi akan terus
meningkat di setiap tahunnya, utamanya sejalan dengan semakin meningkatnya
jumlah penduduk dan adanya perubahan pola makan rakyat Indonesia. Di
Indonesia, konsusmsi gandum telah meningkat pesat akhir-akhir ini sehingga
impor gandum pada tahun 2012 tercatat mencapai 7.4 juta ton (Siregar, 2012).
Dalam meningkatkan ketersediaan gandum di Indonesia, Kementerian
Koordinator Perekonomian bekerja sama dengan Pemerintah Slovakia telah
melaksanakan uji coba penanaman gandum di 7 (tujuh) provinsi yaitu Sumatera
Barat, Sulawesi Selatan, Jawa Tengah, Jawa Barat, Jawa Timur, Bengkulu dan
Papua. Di Sumatera Barat telah dilakukan pengujian multilokasi di empat
kabupaten kota. Di antara daerah-daerah yang telah diuji, Kabupaten Solok adalah
salah satu tempat yang ideal untuk budidaya gandum. Hal ini dibuktikan dengan
hasil penelitian yang telah dilakukan oleh Hariandi (2012) bahwa benih gandum
yang ditanam di Kabupaten Solok mampu beradaptasi dengan baik.
Demi medukung perkembangan dan pertumbuhan gandum, beberapa
penelitian telah dilakukan dengan cara memberikan berbagai macam perlakuan.
Menurut Supirin, 2004 (cit. Jedeng, 2011) menyatakan dalam menunjang
peningkatan kualitas tanah perlu dilakukan usaha untuk mempertahankan atau
menaikkan bahan organik, salah satu caranya adalah dengan menggunakan pupuk
kandang. Selain itu, Proyek Penyuluhan Pertanian Tanaman Pangan (1980) juga
menyatakan bahwa kandungan hara tanah dapat ditingkatkan dengan pemberian
pupuk kandang. Oleh karena itu, Penelitian dengan menggunakan berbagai pupuk
organik yang diterapkan pada tanaman gandum pun telah dilakukan.
Di Kabupaten Solok khususnya di nagari Koto Gaek Guguk kecamatan
Gunung Talang, ketersedian pupuk kandang cukup banyak terutama pupuk
kandang sapi. Para petani banyak memelihara sapi dan kotoran dari sapi tersebut
dimanfaatkan untuk dijadikan pupuk. Selain itu, kondisi geografisnya juga ideal
untuk budidaya gandum karena memiliki ketinggian 750-800 mdpl. Menurut
Suharti (2001), gandum di Indonesia mempunyai pertumbuhan yang baik pada
ketinggian 800 mdpl.
Menurut Sarwanto dan Widiastuti (2000), pemberian dosis pupuk organik
bervariasi pada tanah yang haranya sangat rendah dan strukturnya padat adalah
berkisar antara 5-15 ton/ ha, 15-20 ton/ ha atau 20-30 ton/ ha. Sedangkan
Margono dan Sigit (2000) menyarankan dosis pupuk organik sebanyak 5-15 ton/
ha.
Berdasarkan uraian yang telah diungkapkan di atas, maka dilakukan
Penelitian yang berjudul “Pengaruh dosis pupuk kandang sapi terhadap
pertumbuhan dan hasil tanaman gandum (Triticum aestivum L.) di
Kecamatan Gunung Talang Kabupaten Solok”. Tujuan dari penelitian ini
adalah untuk mendapatkan dosis pupuk kandang sapi yang terbaik terhadap
pertumbuhan dan hasil tanaman gandum. Adapun hipotesis dari penelitian ini
adalah pemberian pupuk kandang sapi dengan dosis yang berbeda akan
memberikan pengaruh yang berbeda terhadap pertumbuhan dan hasil tanaman
gandum
Pond Productivity and Water Quality in Various Vaname Shrimp (Litopenaeus vannamei) Farming Systems at BPBAP Ujong Batee Aceh Besar
Full text linkAbstract. Traditional shrimp farming systems are generally susceptible to disease outbreaks, resulting in low productivity. However, the application of farming technology can reduce these risks. This study aims to calculate the production and examine pond water quality in vannamei shrimp culture by applying semi-intensive, intensive, and super-intensive farming systems through direct measurements and field observations. The results showed that the highest productivity was produced in super-intensive ponds at 5.4 kg/m2, in intensive systems at 2,325 kg/m2, and in semi-intensive farming systems at 0.575 kg/m2. The semi-intensive salinity ranged from 30.8 ppt to 35.1 ppt, the super-intensive salinity ranged from 29.2 to 31.9 ppt, and the semi-intensive salinity ranged from 30.9 to 34.2 ppt. The temperature ranges from 26.7 to 28.5°C for semi-intensive culture, 25.9 to 28°C for super-intensive farming, and 27.8 to 29.3°C for semi-intensive farming. The pH in the semi-intensive farming system is 7.9-8.3, the super-intensive pH is 7.7-8.6, and the semi-intensive system is at pH 7.7-8.2. Dissolved oxygen levels range from 4.0 to 5.9 ppm in intensive shrimp farming, 3.0 to 3.6 ppm in super-intensive shrimp farming, and 3.2 to 4.0 ppm in semi-intensive shrimp farming. Therefore, it can be concluded that the higher the farming technology applied, the higher the ponds' productivity. Meanwhile, differences in farming systems do not impact changes in water quality.

Perbedaan metode budidaya tidak berdampak pada perubahan kualitas air atau ketiga metode budidaya tersebut berdampak yang sama terhadap kualitas air
Suitability analysis of spiny lobster mariculture zones in Sabang waters, Indonesia
Full text linkThe lobster aquaculture industry has a high dependence on natural catch. Hence, lobster farming has become necessary. The waters in Sabang have the potential for developing lobster mariculture, but data is not yet available on the conditions of the aquatic environment that are suitable for lobster farming. This research aims to determine which locations are suitable for lobster mariculture activities in the waters of Sabang. The research parameters are divided into geographics, physicochemical, and supporting parameters. The geographical parameters group was collected through in-situ observations, and physicochemical parameters were measured in-situ and laboratory tests, supporting parameters through observations. Initial data analysis used the SAW (Simple Additive Weighting), AHP (Analysis Hierarchy Process) methods, and spatial analysis to determine the suitability of lobster cultivation zones with the Geographic Information System (GIS). From the observations of geographical parameters, the three locations of the observation station were in the very suitable category. The results of measuring physicochemical parameters group in three research locations were very suitable. Based on observations of other supporting parameters, Lhok Krueng Raya is very suitable for the cultivation zone, while Teupin Sirui and Lhok Weing are suitable. The findings of this research indicate that location protection, accessibility, DO, and COD are limiting parameters for selecting a suitable location for lobster mariculture in Sabang waters.

Fisheries rehabilitation in post-tsunami Aceh: Status and needs from participatory appraisals
Full text linkThe widespread and long-term nature of the tsunami damage in Aceh province, Indonesia has threatened the continued use of coastal and fisheries resources. This article describes the application of the Rapid Appraisal of Fisheries Management System (RAFMS) methodology and presents key findings from the participatory appraisals in 15 study sites. The focus is on changes in the number and types of fishing boats and fishing effort, consumption and marketing flow patterns and community perspectives on livelihood options. The level of aid (for new boats), mainly from international organizations, has been unevenly distributed with the number of boats in 13 of 15 villages still being well below the pre-tsunami levels. A focus on supplying small vessels may put increased fishing pressure on the near-shore zone. Consumption data and marketing flows suggest that most fishing villages are supplying outside markets and adding considerably to the wider food security of the province. Despite the tsunami, marine fisheries-related livelihoods are still preferred, although there are indications for the potential expansion of livelihoods into the culture of new species. Alternative resource-based livelihoods need to be tested and refined to fit the needs of the current conditions in Aceh to provide viable options for eliminating hunger and reducing poverty.Disaster, Tsunami
