Abstract

Torbangun (Plectranthus amboinicus) merupakan tanaman obat dari keluarga Lamiaceae. Pada masyarakat Batak, daun torbangun digunakan untuk meningkatkan produksi air susu. Keragaman kandungan fitokimia dapat ditingkatkan salah satunya dengan teknik iradiasi sinar gamma untuk program pemuliaan tanaman. Pada penelitian ini, metode metabolomik yang tidak tertarget digunakan untuk mengevaluasi profil senyawa pada bagian daun tanaman mutan dari iradiasi sinar gamma dan kontrol. Kandungan senyawa planlet mutan dan kontrol dianalisis dengan GC-MS. Data GC-MS dianalisis dengan kemometrik dengan menggunakan hierarchical cluster analysis (HCA). Keragaman kandungan kimia ditunjukkan oleh planlet mutan dan kontrol daun torbangun. Hasil analisa planlet kontrol torbangun menunjukkan terdapat lima senyawa utama diantaranya hydroxymethylfurfurole (35,15%), brevifolin (7,69%), 3-Dihydro-3,5-Dihydroxy-6-Methyl-4H-Pyran-4-one (DDMP) (13,13%), stigmasterol (6,51%) dan ferruginol (8.63%). Hasil analisa mutan torbangun memiliki kandungan senyawa DDMP (19,57%), neophytadiene (8,47%), linolenic acid (9,10%), ferruginol (7,61%), stigmasterol (14,14%) dan gamma.-sitosterol (7,08%). HCA menunjukkan tiga komponen senyawa yang berbeda antara planlet kontrol dan mutan yaitu kenaikan kandungan senyawa DDMP dan stigmasterol, serta penurunan kandungan hydroxymethylfurfurole pada mutan torbangun.

Abstract

Penelitian bertujuan mendapatkan data dan informasi morfofisiologi kejadian gugur bunga dan buah (fruit-drop) pada tanaman cabai terhadap pemberian zat pengatur tumbuh (ZPT) auksin (IAA dan IBA) dan GA3. Penelitian disusun berdasarkan Rancangan Petak Terpisah dalam rancangan acak kelompok dengan 3 ulangan. Petak utama adalah 3 jenis ZPT yaitu IAA, IBA, dan GA3. Anak petak yaitu konsentrasi perlakuan yang terdiri dari 5 taraf (ppm) yaitu 0, 25, 50, 75, dan 100 ppm. Data yang diperoleh dianalis menggunakan software STAR dan jika terdapat beda nyata diuji lanjut dengan Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan IAA, IBA, dan GA3 serta konsentrasi perlakuannya tidak berpengaruh nyata terhadap jumlah bunga tinggal maupun bunga gugur pada tanaman cabai besar. Namun, hasil penelitian menemukan bahwa perlakuan ZPT menghasilkan jumlah bunga tinggal yang lebih banyak dibandingkan bunga gugur. Pemberian IAA 25 ppm menghasilkan jumlah buah tinggal tertinggi dibandingkan konsentrasi IAA lainnya. Peningkatan konsentrasi GA3 cenderung meningkatkan jumlah buah tinggal dan tertinggi pada konsentrasi GA3 100 ppm. Interaksi antara jenis ZPT dan konsentrasi pemberiannya berpengaruh nyata terhadap bobot per buah. Perlakuan GA3 100 ppm menghasilkan bobot per buah tertinggi. Peningkatan konsentrasi auksin cenderung menurunkan bobot per buah. Pemberian IBA 100 ppm menurunkan panjang buah cabai besar.

Abstract

Jambu air cincalo memiliki aktivitas respirasi non-klimakterik dengan kadar air yang tinggi, sehingga penanganan pascapanen yang tidak tepat akan memicu pertumbuhan cendawan. Penelitian ini bertujuan untuk mengetahui pengaruh edible coating dari oleoresin daun kemangi dan menentukan konsentrasi yang tepat untuk memperpanjang umur simpan buah jambu air cincalo. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal, terdapat 4 perlakuan yang merupakan jenis konsentrasi oleoresin daun kemangi yang terdiri dari K0 (tanpa penambahan oleoresin), K1 (0,3% oleoresin), K2 (0,6% oleoresin) dan K3 (0,9% oleoresin) dengan 3 ulangan. Peubah yang diamati adalah susut bobot, total padatan terlarut, total asam buah, kandungan vitamin C dan organoleptik. Hasil penelitian menunjukkan bahwa perlakuan konsentrasi oleoresin daun kemangi berpengaruh tidak nyata terhadap peubah yang diamati, meliputi susut bobot, total padatan terlarut, total asam buah, dan kandungan vitamin C. Semua perlakuan dengan penambahan oleoresin maupun tanpa penambahan oleoresin daun kemangi cenderung memberikan hasil yang sama terhadap buah jambu cincalo.

Abstract

Watermelon [Citrullus lanatus (Thunberg) Matsum & Nakai] is a plant that is widely cultivated and contains important nutritional compounds such as citrulline, arginine, and glutathione. In the last few years, the consumption of vegetables and fruits in Indonesia has tended to increase but cannot be fulfilled by domestic production. Yields are influenced by the character of yield components. This research aims to study the relationship between yield component traits and yield of watermelon. The study was arranged in augmented design and planting material are 75 watermelons genotypes and 3 checks varieties. The results showed that there are some characters of yield components that correlated with yields. The characters of yield components that have positive genetic correlation and positive phenotype correlation with fruit weight are stem length, number of branches, fruit stalk length, fruit length, fruit diameter, thickness of pericarp, number of seeds per plant, and weight of seeds per plant. The yield components characters that have a negative genetic correlation with fruit weight are day to flowering. The characters of yield components that have positive genetic and phenotype correlation with seed weight per plant are fruit weight, stem length, fruit length, fruit diameter, number of seeds per plant, seed length, and seed width. The Characters of yield components that have a negative genetic correlation with seed weight are day to flowering and the first female flower emerges. The characters of yield components that correlate with the yield are used as selection markers for indirect selection.

Abstract

Oyster mushrooms have the conditions of growing at low temperatures and high relative humidity, so when you want to cultivate it is needed an appropriate environment for the growth and development of oyster mushroom. Banjarbaru City tends to have high temperatures with a relative humidity that tends to below. This is quite different from the requirements for growing oyster mushrooms which require low temperatures with relatively high humidity. One of the easiest and cheapest methods to maintain temperature and relative humidity to remain ideal and appropriate is to water the surrounding oyster mushrooms growing media, so knowledge of the most appropriate and ideal watering frequency for growth and development of oyster mushrooms is needed. The environmental design used was a Completely Randomized Design (CRD), a single factor with 4 treatments, 5 replications, so that 20 experimental units were obtained. The treatments are p1 = once watering per day, p2 = twice watering per day, p3 = three times watering per day, p4 = four times watering per day. The result showed that the watering frequency showed significant difference to the growth time of oyster mushroom shoots and the wet weight of oyster mushrooms. The best treatment in accelerating the growth time of oyster mushroom shoots and increasing the wet weight of oyster mushrooms is four times watering frequency per day.

Abstract

The study aims to analyze the differences in the development of corn cultivation in peat soils between no-burning and traditional methods or with burning in Rasau Jaya District, Kubu Raya District. The fact that currently clearing forests is still using burning on agricultural land in general and especially on peat soil that is feared to experience underground burning is difficult to overcome and cause many losses. The development of corn on land without burning on peat soil is a solution for the community in maintaining ecosystem sustainability. The explanatory research is directed at testing hypotheses and following research objectives. Data collection by interview and questionnaire to 60 respondents were corn farmers on peat soil. The average difference test is used in explaining the difference in yield between the two methods of planting on peat soil. The results found that there were significant differences in the application of corn cultivation on peat soil without burning compared to the traditional method on the variables fertilizer, pesticide, business costs, and yields. In contrast, the planting area variable had no significant difference.

Abstract

Red rice is known to have advantages, i.e. contain fiber and anthocyanin that have functional properties. The potential of red rice needs to be explored more intensively through various studies. One effort to develop brown rice as food is to process it into flour. In the process of flour processing, there are several steps that must be considered to get flour with good physicochemical properties, such as drying and grinding. The purpose of this research was to learn the effect of drying time and temperature on the physicochemical characteristics of red rice flour. Randomized Block Design factorial was used in this research. The treatment factors were drying time (A) and drying temperature (B). Factor A consisted of three levels i.e. 1 hour, 2 hours, and 3 hours, and factor B also consisted of three levels i.e. 50°C, 55°C, and 60°C. The parameters observed in this study were yield, bulk density, water holding capacity, swelling power, solubility, moisture content, and amylose content of red rice flour. The results showed that the drying times and temperatures significantly reduced yield, bulk density, and moisture content, but significantly increased water holding capacity, swelling power, solubility, and amylose content of red rice flour. The moisture content of red rice flour was in accordance with the standards (SNI 3549; 2009).
