Abstract

The use of one type live food in the larval rearing of vannamei shrimp is insufficient for maximum larval development. This research was aimed to evaluate the use of phytoplankton Chaetoceros calcitrans and Thalassiosira weissflogii and its combination as food to the growth and survivorship of white pacific shrimp Litopenaeus vannamei. The research used prawn larvae at stadia Nauplius4-5 with 150/ litre larval density. The larvae were fed and their effects with 3 kinds of live food, C. calcitrans (A), T. weissflogii (B), and combination of both types (C) for each treatment with five replications.The data was analysed using SPSSV.16. Result showed that the survival rate for treatment A was of 55.04+11.81%, treatment B was of 68.22+6.80%, and treatment C was of 77.04+4.63%. This indicated that treatment A gave significantly different on survival rate (P<0.01) than treatment B and C. Treatment B and C were not significantly different (P>0.05). We recomended the use of combination both of C. calcitrans and T. weisflogii to provide maximum survival rate for vannamei shrimp postlarvae.

Abstract

Pemberdayaan petani merupakan proses beraneka segi yang melibatkan peningkatan kapasitas mereka untuk meningkatkan produktivitas pertanian, beradaptasi dengan tantangan, dan mencapai mata pencaharian yang berkelanjutan. Penelitian ini bertujuan untuk menganalisis tingkat keberdayaan petani dan pengaruh karakteristik petani, intensitas pemberdayaan dan dukungan eksternal terhadap tingkat keberdayaan petani. Penelitian dilaksanakan dengan pendekatan kuantitatif dengan menjelaskan pengaruh hubungan dan pengaruh antar variable-variabel di Kecamatan Keumala, Kabupaten Pidie pada bulan Agustus-September 2023. Pengumpulan data dilakukan melalui observasi dan wawancara mendalam terhadap 130 orang responden. Analisa data dilakukan dengan metode deskriptif dan menggunakan teknik Partial Least Square (PLS) melalui bantuan aplikasi smartPLS.3.2.9. Hasil penelitian ini menunjukkan bahwa tingkat keberdayaan petani padi IP 300 di Kecamatan Keumala dikategorikan tinggi. Faktor-faktor yang secara signifikan memengaruhi keberdayaan petani padi dalam program IP 300 di Kabupaten Pidie adalah intensitas pemberdayaan (intensitas pengembangan kemampuan teknis, intensitas pengembangan perilaku inovatif, dan ketepatan metode penyuluhan) dan dukungan eksternal (ketersediaan infrastruktur, dukungan tokoh tani, dan dukungan kebijakan pemerintah), sedangkan karakteristik petani (pendidikan non formal, luas lahan dan motivasi) berpengaruh tidak sifinikan terhadap tingkat keberdayaan petani padi program IP 300 di Kabupaten Pidie.

Tujuan dari kegiatan ini agar masyarakat di tempat ini dapat memproduksi pangan sayuran untuk dikonsumsinya sehingga dapat meminimalkan pengeluaran, sekaligus meningkatkan kesehatannya. Kegiatan PkM ini dilaksanakan tanggal 18 November 2023 dihadiri oleh 36 peserta. Kegiatan ini dilakukan dalam beberapa tahapan kegiatan, yakni: pembukaan, penjelasan tentang vitamin B1, pengisian kuesioner, quiz, pemberian bahan dan alat, dan foto bersama. Hasil kegiatan ini menunjukkan peserta merasa senang karena mendapatkan pengetahuan dan keterampilan bercocok tanam sayuran di pekarangannya menggunakan vitamin B1 cair sehingga mereka dapat langsung mempraktekkanya sendiri setelah kegiatan PkM ini selesai. Peserta akan menggunakan vitamin B1 atau tidak di masa mendatang tergantung hasil dari tanaman yang ditanam menggunakan vitamin B1 sesuai yang diajarkan tim PkM UT.

Abstract

This study aims to analyze the influence of fuel prices (BBM) and sea wave height on the price of mackarel tuna in Banda Aceh City, with a case study at the Ocean Fisheries Port (PPS) Kutaraja Lampulo. The study uses monthly secondary data from 2019 to 2024 and applies a Linear Regression Model for analysis. The regression results indicate that both fuel prices and sea wave height have a significant effect on mackarel tuna prices at the 0.05 significance level. The wave height variable shows a positive coefficient, indicating that higher waves tend to increase mackarel tuna prices. This finding is consistent with the theory that extreme sea conditions hinder fishing activities, reduce fish supply, and consequently increase prices. However, the fuel price variable shows a negative coefficient, contrary to the economic theory that rising fuel prices should increase commodity prices due to higher production costs. This result is likely due to the stability of fuel prices (diesel fuel) during the observation period and the operational efficiency achieved through the use of technology by fishermen, allowing them to maintain or even improve catch volumes despite rising fuel prices.

Abstract

Media internet sudah banyak diterapkan untuk berbagai kepentingan dalam dunia pendidikan. Meskipun media internet sudah dikenal luas, mahasiswa pendidikan tinggi jarak jauh yang tinggal di daerah perdesaan di beberapa wilayah Indonesia masih menghadapi permasalahan dalam mengaksesnya. Tujuan penelitian ini adalah untuk menganalisis hubungan antara perilaku mahasiswa dalam mengakses internet dan faktor-faktor yang mempengaruhinya. Perilaku akses internet mencakup tiga komponen utama yaitu kogintif, afektif, dan konatif. Faktor-faktor yang mempengaruhi perilaku akses internet meliputi faktor lingkungan, karakteristik pesan, dan kredibilitas sumber. Penelitian survei ini dilaksanakan di wilayah Surakarta dengan sampel 320 responden. Data dianalisis dengan metode Model Persamaan Struktural. Hasil analisis menunjukkan bahwa faktor lingkungan berpengaruh nyata terhadap perilaku mahasiswa dalam mengakses internet. Ternyata peningkatan akses internet lebih mudah dilakukan dengan peralatan berupa handphone yang lebih murah, namun dibutuhkan pengembangan perangkat lunak yang sesuai dengan peralatan tersebut. Strategi lain yang mendukung peningkatan akses adalah peningkatan kemampuan mahasiswa dalam menelusur informasi.
