Abstract

One of the main requirements for small-scale cultivators is that they can be used in small plots of land and have simple design and technology. However, many planting tools on the market today are not suitable for narrow land conditions. Therefore, this study aims to design and develop a corn seed planter that can be operated in narrow areas and can improve seed planting efficiency and accurate seed placement. The research parameters observed were the distance between plants, the depth of the planting holes, the number of seeds per planting hole, and the efficiency of using the tool. The results of the research show that the planting tools that have been designed and developed are very easy and practical to operate by farmers on narrow land. The distance between plants varies between 21.3 – 24.2 cm. The depth of the planting hole ranges from 5.4 – 7.1 cm. The distribution of the number of holes filled with 0 seeds was 3.00%, filled with 1 seed was 90.38%, and filled with 2 seeds was 6.62%. Planter efficiency data is 85.61%. This data shows that this cultivator meets the minimum standards for the manually operated cultivator category. Keywords: Distance between seeds, Efficiency, Empty hole, Land productivity, Planting hole.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh rasio bunga rosella dan daun stevia terhadap mutu dari teh rosella-stevia. Penelitian ini disusun menggunakan Rancangan Acak Lengkap (RAL). Perlakuannya yaitu rasio bunga rosella : daun stevia (100:0, 85:15, 75:25, 65:35 dan 55:45(%)) dengan 3 kali ulangan sehingga diperoleh 15 kali percobaan. Parameter yang diamati adalah aktivitas antioksidan, nilai pH, kadar air, kadar abu, warna (colorimeter) dan organoleptik (aroma, rasa, dan warna). Hasil pengamatan dianalisis dengan menggunakan analisis keragaman (Analysis of Variance) pada taraf 5% menggunakan aplikasi Co-Stat. Apabila terdapat beda nyata, dilakukan uji lanjut menggunakan uji Beda Nyata Jujur (BNJ). Hasil penelitian menunjukkan perlakuan rasio bunga rosella dan daun stevia memberikan pengaruh berbeda nyata terhadap aktivitas antioksidan, nilai pH, kadar air, kadar abu, warna oHue, nilai *L, aroma (skor), rasa (hedonik dan skor) dan warna (hedonik dan skor) namun tidak berbeda nyata terhadap uji aroma secara hedonik. Perlakuan terbaik teh rosella-stevia yaitu S3 rasio bunga rosella dengan daun stevia (65%:35%) dengan aktivitas antioksidan sebesar 87,61%; nilai pH 3,41; kadar air 7,69%; kadar abu 7,67%; nilai L* 58,76 dan nilai oHue 6,78 berwarna merah keunguan, beraroma langu, berasa manis, disukai oleh panelis serta sesuai dengan SNI 3836 tahun 2013 tentang mutu teh kering dalam kemasan.
