Abstract

This study aims to determine the effect and concentration of kinetin on potato mericlon shoots and to determine the best effect and concentration of coconut water on potato mericlon shoots. This research was conducted at the Plant Genetics Laboratory, Faculty of Agriculture, Sam Ratulangi University, Manado. This study used a completely randomized design (CRD) which consisted of seven treatments namely A0 (control/no treatment), A1 (Kinetin 0.5 ppm), A2 (Kinetin 1.5 ppm), A3 (Kinetin 1.5 ppm), A4 ( Coconut Water 5%), A5 (Coconut Water 7.5%), A6 (Coconut Water 10%). The variables observed were: shoot height, number of leaves, number of roots, and fresh weight. The results showed that the treatment of kinetin and young coconut water had a significant effect on the parameters of shoot height, namely A6 (6.74 cm), number of leaves, namely A1 (8.2 strands) and A6 (8.2 strands), number of roots, namely A3 (11 .3 units) and a wet weight of A3 (0.4591 gram). In this study, a kinetin concentration of 0.5 ppm was good for increasing the number of leaves, and a concentration of 10% coconut water was good for increasing shoot height. Keywords: Potato, Tissue Culture, PGR, Kinetin, Coconut Water. Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh dan konsentrasi kinetin terhadap tunas meriklon kentang dan untuk mengetahui pengaruh dan konsentrasi terbaik air kelapa terhadap tunas meriklon kentangPenelitian ini dilaksanakan di Laboratorium Genetika Tanaman, Fakultas Pertanian, Universitas Sam Ratulangi Manado. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari tujuh perlakuan yaitu A0 (kontrol/tanpa perlakuan), A1 (Kinetin 0,5 ppm), A2 (Kinetin 1 ppm), A3 (Kinetin 1,5 ppm), A4 (Air Kelapa 5%), A5 (Air Kelapa 7,5%), A6 (Air Kelapa 10%). Variabel yang diamati adalah: tinggi tunas, jumlah daun, jumlah akar, dan berat basah. Hasil penelitian menunjukan pemberian perlakuan kinetin dan air kelapa muda berpengaruh nyata terhadap parameter tinggi tunas yaitu A6 (6,74 cm), jumlah daun yaitu A1 (8,2 helai) dan A6 (8,2 helai), jumlah akar yaitu A3 (11,3 unit) dan berat basah yaitu A3 (0.4591 gram). Pada penelitian ini, konsentrasi kinetin 0,5 ppm sudah baik untuk peningkatan jumlah daun, dan konsentrasi air kelapa 10% sudah baik untuk meningkatkan tinggi tunas. Kata kunci: Kentang, Kultur Jaringan, ZPT, Kinetin, Air Kelapa

Abstract

This research aims to obtain data on weed types that have the potential to be used as medicinal plants and are used by the community in the district. North Bolaang Mongondow Includes 1). Sangkub District, 2) Bintauna District, 3) Kaidipang District, 4) Pinogaluman District. The methods used in this research were field observations and interviews with healers and people who use weed as a traditional medicinal plant. The data/samples that will be taken over 4 sub-districts. The ethnic diversity that exists in Indonesia means that the use of weed as medicine is increasingly diverse. North Sulawesi Province has a wealth of plants as traditional medicines which can be processed to national standards into herbal medicines. The indigenous population in North Bolaang Mongondow Regency consists of the Kaidipang tribe and the Bintauna tribe. Various ethnic groups, including the Sangihe ethnic group and the Mongondow ethnic group, still use weed as an ingredient in traditional medicine. Weeds are wild plants defined as nuisance plants because they interfere with farmers' activities in cultivating crops and can reduce crop production. Apart from disturbing cultivated plants, weeds can be used as medicinal raw materials. Many types of weeds are used by the community as traditional medicine. Certain types of weed have been developed in the form of industrial-scale medicines. These weed species include Peperomia pellucida (L.), Cyperus rotundus L., Heliotropium indicum L., Eleusine indica (L.) Gaernt, Ageratum conyzoides L. The results of the research show that people in East Bolaang Mongondow Regency still use weed as a mixture of traditional medicinal ingredients. Keywords: medicinal plants, potential of weeds as medicinal plants Abstrak Tujuan penelitian ini adalah memperoleh data jenis gulma yang berpotensi sebagai tumbuhan obat dan dimanfaatkan masyarakat di Kab. Bolaang Mongondow Utara Meliputi 1). Kecamatan Sangkub, 2) Kecamatan Bintauna, 3) Kecamatan Kaidipang, 4) Kecamatan Pinogaluman. Metode yang digunakan dalam penelitian ini adalah observasi lapangan, wawancara  pengobat dan  masyarakat pengguna gulma sebagai tumbuhan obat tradisional.  Data/sampel yang akan diambil meliputi 4 kecamatan.  Keanekaragaman etnis yang ada di Indonesia menyebabkan pemanfaatan gulma sebagai obat juga semakin beraneka ragam.  Provinsi Sulawesi Utara memiliki kekayaan tumbuhan sebagai obat tradisional yang bisa diolah berstandar nasional menjadi obat herbal.  Penduduk asli di Kabupaten Bolaang Mongondow Utara terdiri dari suku Kaidipang dan Suku Bintauna. Berbagai etnis diantaranya etnis Sangihe, etnis Mongondow masih erat menggunakan gulma sebagai bahan obat tradisional.   Gulma merupakan tumbuhan liar didefinisikan sebagai tumbuhan pengganggu  karena mengganggu kegiatan petani dalam budidaya tanaman dan dapat menurunkan produksi tanaman.  Gulma selain mengganggu tanaman budidaya, dapat dimanfaatkan sebagai bahan baku obat. Banyak jenis gulma yang dimanfaatkan oleh masyarakat sebagai obat tradisional. Ada jenis gulma tertentu sudah dikembangkan dalam bentuk obat skala industri. Spesies gulma tersebut antara lain Peperomia pellucida (L.), Cyperus rotundus L., Heliotropium indicum L., Eleusine indica (L.) Gaernt, Ageratum conyzoides L. Hasil penelitian menunjukkan bahwa masyarakat di Kabupaten Bolaang Mongondow Timur masih menggunakan gulma sebagai campuran ramuan obat tradisional. Kata kunci: tumbuhan obat, potensi gulma sebagai tumbuhan obat.

Abstract

Langsat Punggur Pontianak (Lansium parasiticum) has a high economic value in West Kalimantan, because it involves the thousands of workers who win it. Langsat Punggur Pontianak has unique nutritional and organoleptic characteristics. The purpose of this study was to evaluate the effectiveness of using edible coatings from aloe vera in extending the shelf life of Langsat Punggu Pontianak. The parameters for the tests carried out included weight loss, moisture content, TSS, texture, color, taste, aroma. The results showed that the use of edible coatings combined with cold temperatures could extend the shelf life to 15 days, and if Langsat Punggur Pontianak was stored at room temperature the shelf life would reach 10 days.
