Abstract

Red chili (Capsicum annuum L.) is a featured commodity for horticultural crops which has high economic value and potential to developed in Indonesia. One of the developments which need to be carried out is chili peppers cultivation on riparian tropical wetland during transition period (drought-flood).The aim of this study was to evaluate the growth response of three varieties of red chili to water stress conditions, namely shallow water table (SWT) at vegetative phase. This study used completely randomized design with chili pepper varieties treatment which consisting of Laris (V1), Laba F1 (V2), and Laju F1 (V3) during seven days of SWT and seven days of recovery. The results showed that SWT conditions had an effect in the form of an increase in the shoot length, root length and number of leaves of chili plants, and decreased after recovery conditions, except for root length, while the three varieties used in the study did not show significantly affected by SWT. In the results of agronomic characters, namely shoot dry weight, root dry weight, and total dry weight, there was also an increase in the three varieties of chili plants, both after SWT treatment and after recovery. The highest adaptability to shallow water table conditions in order are the varieties Laju F1, Laga F1 and Laris. Red chili pepper plants is categorized as resistant horticultural commodity on shallow water table stress conditions at vegetative phase and potential to be cultivated at riparian tropical wetland during transition period.

Abstract

ABSTRACT Sanren F1 shallot is a type of TSS variety that is widely cultivated by Indonesian onion farmers. The cultivation of Sanren F1 shallots is faced with the constraints of non-uniform germination and low seed viability, thus affecting seed quality and yield of TSS shallots. Plasma light radiation is one of the fast, economical and pollution-free plant breeding methods to improve seed performance and yield. This study aims to determine the effect of plasma light period on the germination rate of shallots from TSS seeds of Sanren F1 variety. The research design used was a single-factor Completely Randomized Design (RAL). The factor used is the irradiation period with 6 levels, namely: P0 (control), P1 (5 minutes radiation), P2 (10 minutes radiation), P3 (15 minutes radiation), P4 (20 minutes radiation), and P5 (25 minutes radiation). The variables observed were germination power, germination rate, seed vigor and sprout height. The data obtained were analyzed using Analiysis of Variance (ANOVA) at 95% confidence level for the formation of the results significantly influenced or not. If influential then continued with Duncan's Multiple Range Test (DMRT). The results showed that plasma light treatment at the irradiation level of 15 minutes (P3) gave a real effect on the growth parameters, namely germination height and was able to increase the germination and seed vigor to 100%.

Abstract

The hard and thick structure of snakefruit seeds makes it difficult for snakefruit seeds to germinate, therefore efforts are needed to break the dormancy of snakefruit seeds. The aim of the research was to determine the method of breaking dormancy and the appropriate seed planting position to increase the viability of snakefruit (Salacca edulis Reinw) seeds, which was carried out at the Green House of the Agriculture, Fisheries and Forestry Extension Center (BP3K). The research method uses a factorial pattern in a completely randomized design. The first factor is the dormancy breaking method which consists of 5 levels, namely control, atonic, gibberellin (GA3), 60oC hot water, and sanding. The second factor is the position of planting seeds which consists of 3 levels, namely upright, lying down and upside down. Data analysis was carried out using ANOVA with a DMRT further test at 5% level. The research results showed that the method of breaking dormancy had an effect on the viability of snakefruit seeds. A good method of breaking dormancy is with GA3. The position of seed planting influences the viability of snakefruit seeds. The positions for planting seeds that have a good effect are the upright and lying positions. There was an interaction between the method of breaking dormancy using GA3 and the planting position of the lying seeds on the viability of the snakefruit seeds.

Abstract

Emergency Food Product (EFP) is a special food used in emergencies such as disasters by paying attention to criteria such as safe, palatable, easy to distribute, easy to consume, and nutritionally complete. Biscuits are processed products that can be developed to meet EFP criteria. Biscuits have a crunchy and dry texture so that they can last a long time and are favored by the majority of people. The main ingredient in making biscuits is wheat flour. However, it can be modified by utilizing local commodities such as porang and corn. Therefore, research needs to be done to get the right formulation for making biscuits made from local flour so that they can meet EFP criteria. This study used the factorial Complete Randomized Design (RAL) method, which consists of two factors, local flour formulation and dough pretreatment temperature. Analysis of the chemical characteristics including moisture, ash, protein, fat, carbohydrate, crude fiber content, and calories. The results showed that the formulation provided significant differences in moisture, ash, fat, protein, crude fiber, and carbohydrate content of local flour biscuit prototypes. The temperature difference of pretreatment (-18°C or 4°C) for 30 minutes before molding provides significant differences in moisture, fat, crude fiber, and carbohydrate content of local flour biscuit prototypes. Based on the number of calories per 50 gr of products, all prototypes of local flour biscuits with pretreatment at -18°C showed calories with an average of 234 kcal, meeting the calorie density requirements of emergency food products, which is a minimum of 233 kcal / 50 gr and a maximum of 250 kcal / 50 gr

Abstract

Catharanthus roseus L., atau tapak dara menarik perhatian luas karena kekayaan senyawa bioaktifnya, terutama flavonoid yang bermanfaat bagi kesehatan. Oleh karena itu, diperlukan teknik perbanyakan yang cepat dan efektif untuk memperoleh metabolit sekunder pada tanaman ini. Tujuan penelitian adalah mempelajari pengaruh aplikasi Elicitor Cu2+ terhadap morfologi kalus Catharanthus, dan mengetahui konsentrasi Elicitor Cu2+ terbaik dalam meningkatkan kandungan senyawa flavonoid pada Catharanthus. Penelitian kultur kalus dilaksanakan di Laboratorium Biosains dan Bioteknologi Reproduksi Tanaman, Gedung Teaching Industry, Jurusan Fakultas Pertanian Universitas Hasanuddin Makassar, dan analisis senyawa flavonoid dilakukan di Laboratorium Farmakognosi-Fitokimia Fakultas Farmasi Universitas Muslim Indonesia Makassar. Penelitian ini menggunakan rancangan acak lengkap (RAL) empat taraf konsentrasi Cu2+ yaitu 0 ppm, 4 ppm, 6 ppm, dan 8 ppm dengan tiga kali pengulangan. Setiap satuan percobaan terdiri dari 3 botol kultur. Data dianalisis menggunakan analisis varian dan uji lanjut BNJ 5%. Hasil penelitian menunjukkan bahwa penambahan elisitor Cu2+ 4-8 ppm pada media pertumbuhan kalus tidak bersifat toksik pada kalus, sehingga sel-sel kalus masih aktif membelah yang ditunjukkan oleh kalus yang kompak dan berwarna kuning kehijauan. Penambahan elisitor Cu2+ dengan konsentrasi 6 ppm mampu meningkatkan kandungan senyawa flavonoid pada kultur kalus Catharanthus roseus. Penggunaan elisitor Cu2+ berpotensi untuk dikembangkan untuk memproduksi senyawa sekunder pada tanaman obat.

Abstract

Increased plant productivity can be achieved through the development of organic fertilization technology that utilizes local organic matter that is easily accessible to farmers. An example is the use of manure from cow and goat manure, as well as forage such as kirinyuh and gamal. This approach offers a solution to the low productivity of rice in drylands. The use of organic fertilizers in various doses is expected to improve soil nutrient status while increasing rice productivity in dry land. This research was carried out on farmers' land in Ponu Village, Biboki Anleu District, North Central Timor Regency, East Nusa Tenggara, which is located in the RI-RDTL border area, precisely the Oekusi section. The experiment in this study was designed in a Group Randomized Design consisting of 10 treatments. The treatment is No Fertilization (P0D0), 10 tons of cow manure fertilizer (PsD1), 20 tons of cow manure fertilizer (PsD2), 30 tons of cow manure (PsD3), 10 tons of goat manure (PkD1), 20 tons of goat manure (PkD2), 30 tons of goat manure (PkD3), 10 tons of forage (PhD1), 20 tons of forage (PhD2), and Forage fertilizer with a dose of 30 tons (PhD3). Each treatment was repeated 4 times so that there were 40 experimental plots. The results showed that the combination of goat manure treatment with a dose of 30 tons/ha (PkD3) had a better effect than other treatment combinations. This combination of treatments was able to provide the best observation value on several parameters, namely plant height growth, the number of saplings and the number of panicles per clump as well as the production of dry grain weight harvested per plot.

Abstract

Conventional shallot cultivation has brought negative effects such as chemical pollution, decrease in biodiversity, and fungal pathogen resistance.  The use of organic fertilizer and biopesticides is a good solution to overcome the problems.  This research was done to find optimum dose of siam weed compost combined with biocontrol of avirulent Fusarium oxysporum f. sp. cepae on shallot production.  A single factor arranged in Randomized Complete Design with 3 replications was used.  The treatment was the dose of siam weed compost i.e. A = control, B = 5 tons/ha, C = 10 tons/ha, D = 15 tons/ha, and E = 20 tons/ha.  Siam weed compost was enriched with the biocontrol before used.  The results showed that up to 20 tons/ha, siam weed compost increased only shallot growth of fresh and dry weight of plant.  There was no significant effect to shallot yield.  Incidence of moler disease was very low during the research.

Abstract

Downy mildew Peronosclerospora spp. is an important disease in corn (Zea mays L.). The damage of downy mildew caused by Peronosclerospora spp. is this pathogen can reach 90-100%, especially in corn varieties that are susceptible to downy mildew. So far, most research has only been limited to knowing the incidence of the disease, without being able to describe the spatial distribution pattern of downy mildew in the planting area. This research aims to determine the occurrence of disease and the spatial distribution patterns of downy mildew on a geospatial basis. Samples were taken from three corn fields affected by downy mildew on three fields planted with corn plants that were attacked by downy mildew. Data on the level of infestation, along with its coordinates, were used to create a theoretical semivariogram model, Gaussian, spherical, exponential. The distribution pattern is approached by interpolating attack level data using the kriging method. The research results show that the appropriate theoretical semivariogram model to describe the distribution of P. maydis in the observation area is the Gaussian model. The distribution of pathogens throughout the observation area began with a clustered pattern and evened out at the end of the observation. Foci had a clustered pattern in the first to fourth weeks of observation. Then each foci experienced development, so that the distribution pattern changed to become even after the fifth week of observation.

Abstract

Seeds are generally used for moringa cultivation. However, the seeds produced have a fairly hard seed coat, thus affecting germination and seed vigor. The research by immersing seeds with plant growth regulators (PGR) and a comparison of the composition of planting medium need experimentation to get the maximum PGR concentration and the right composition of the planting medium to grow. The study was conducted using a Split Plot Design with the main plots PGR consisting of Z1 (freshwater), Z2 (Coconut liquid), and Z3 (GA3). The subplot is Plant Medium consisting of M1 (soil: sand: manure-1:1:2); M2 (soil: sand: manure-1:2:1); M3 (soil: sand: manure-2:1:1). Data were examined by Analysis of Variance and continued by DMRT at α 5%. The results of the analysis showed that PGR had a significant effect on plant height, stem diameter, and root length. The composition of the planting medium caused significant differences in plant height, stem diameter, number of leaves, and fresh and dry leaf weight. The interaction between the planting medium and PGR caused differences in stem diameter at 2 and 8 weeks after planting. The recommended PGR treatment is freshwater for longer roots and taller plants. M1 planting media produced the most number and weight of leaves. The combination treatment of Z3M2 produces the largest stem diameter.
