Abstract

Rice (Oryza sativa L.) is a rice-producing plant that is one of the staple foods for the world's population, especially Indonesia. One of the factors causing a decrease in rice production is pests, the main pest of rice plants is the golden snail. The golden snail pest attack occurs on rice plant seedlings, namely in the vegetative phase. The purpose of this study was to determine the effect of giving plant-based pesticides tuba root extract (Derris elliptica) on the mortality and pest intensity of the golden snail (Pomacea canaliculata L.) on rice plants (Oryza sativa L.) Inpari 32 variety. The method used was experimental (trial) using a single factor Randomized Block Design (RBD) with 6 treatments with 5 replications so there were 30 experimental units. Treatment of D. elliptica tuba root extract concentration on rice (Oryza sativa L.) treatment A (Control), B (5g/L), C (7g/L), D (9g/L), E ( 11g/L), and F (13g/L). Tuba root extract at a concentration of 13g/L is the best concentration which gives the highest mortality of 81.60% with the lowest attack intensity value of 29.84%. The LC50 value of the tuba root extract on the golden snail was 2.64g/L, the minimum value was 0.37g/L and the maximum was 4.164 g/L. LT50 takes a minimum of 1 day and a maximum of 9 days with an average time of 6-5 days. The results of calculating the correlation between mortality and the intensity of golden snail attacks on tall rice plants are -0.60. Administration of tuba root extract of D. eliptica was effective against the mortality of the golden snail P. canaliculata and the intensity of the attack by the golden snail P. canaliculata on rice (Oryza sativa L.).

Abstract

The brown planthopper is an important pest in rice cultivation which acts as a vector for viruses that cause grass stunt and hollow stunt disease which can cause rice plants to die or reduce production to the detriment of farmers. This study aimed to obtain a pest control technique capable of suppressing the population and intensity of brown planthopper attacks on rice plants. This study is an experimental study using single-factor Randomized Block Design (RBD) with 4 treatments and 6 replications: C (Control); CC (Combination Control); BC (Biointensive Control); SC (Synthetic Control). The analysis results obtained showed that the SC treatment gave the lowest attack intensity value of 0.00% - 28.67% with a total population of 0 - 89 individuals followed by CC (1.33% - 44.67%) with a total population of 2-114 individuals, BC (2.00%-46%) with a total population of 3 - 103 individuals, and C (2.00% -45.33%) with a total population of 3 - 102 individuals. Synthetic control can be recommended as an alternative pest control technique in reducing the intensity of brown planthopper attacks.

Abstract

Tribolium castaneum is one of stored pests with vast host against stored commodites. The purpose of this research is to know the survivability of T. castaneum and weight loss on rice and corn in the shape of whole grain, broken grain, and flour. This research used single factor Completely Randomized Design (CRD) consisting of 7 treatments with 4 replications: A (control), B (whole grain of rice), C (broken grain of rice), D (rice flour), E (whole grain of corn), F (broken grain of corn). G (corn flour). The observed variables were temperature and humidity, adult mortality, and feed weight loss. The results showed the differences of feed did not give significant effect on T. castaneum mortality but has siginificant effect on feed weight loss. Corn flour has the most weight loss by 8,50grams. This conclude that T. castaneum has high comsumption activity on corn flour.

Abstract

Rambusafruit (Passiflora feotida L.) is a type of wild plant that can be consumed like passion fruit, therefore this fruit is also known as forest passion fruit. Besides being consumed, this fruit can also be used as medicine in humans, such as for the treatment of diarrhea caused by Escherechia coli bacteria. This condition opens up opportunities for the use of Rambusafruit as an anti-bacterial that causes disease in plants. Based on the above phenomenon, the purpose of this study was to determine the secondary metabolic content of the rambutan fruit extract. Laboratory test results through phytochemical tests proved that the rambutan fruit extract contains secondary compounds that have potential as anti-bacterials, including saponins, flavonoids, tannins, triterpenoids, steroids and essential oils.

Abstract

Ultisol is a type of soil that is not very fertile but is commonly used for agriculture. The research aimed to gather information about how the application of rice husk biochar and cow manure, either separately or combined, would affect soil phosphorus levels, the uptake of phosphorus by spring corn plants (Zea mays saccaratha L.), and the weight of the plants when they are wet and when they are dried. The study used a 4x3 Factorial Randomized Block Design, with four levels of biochar and three levels of cow manure, followed by an analysis of variance. The research location is situated at an altitude of around 33 meters above sea level (masl) with soil acidity (pH) ranging from 5.5 to 6.5, and characterized by Ultisol soil type. The parameters observed included soil phosphorus levels, phosphorus uptake by plant stems and leaves, wet weight and oven-dried weight of plant stems and leaves, and wet weight of harvested cobs. The results of the study showed that applying rice husk biochar and manure as single treatments did not have a significant effect on increasing soil phosphorus availability, plant phosphorus uptake, wet weight and dry weight of plant stems and leaves, or baby corn production. However, there was a tendency for each observation parameter to show some improvement

Abstract

The status of arthropod diversity and biodiversity in Jakarta is often ignored, so the development of Plant Disturbing Organisms (Pests) is increasing. This has spurred farmers managing rice fields (Oryza sativa L.) to carry out unwise pest control on the remaining 414 hectares of land. The purpose of this study was to determine how the percentage of arthropod abundance based on order and fluctuations in arthropod populations on several rice fields in Cakung District, East Jakarta, and as information material in pest control based on Integrated Pest Management (IPM) that is appropriate in the field. The method used in this research is non-experimental with a direct survey method in the rice fields of the Maju Bersama (MB), Ujung Menteng (UM), dan Sawah Abadi (SA) in the vegetative planting phase until the harvest of rice plants. From the findings, the highest percentage of arthropod abundance was found in the order Diptera (36.73%), Araneae (19.45%), Hymenoptera (14.20%), Hemiptera (14.03%), Coleoptera (9, 32%), Lepidoptera (4.75%), Odonata (0.73%), Orthoptera (0.57%), Thysanoptera (0.07%), Heteroptera (0.05%), Dermaptera (0.05%), Isoptera (0.03%), and Psocodea (0.02%). Fluctuations in arthropod populations during one growing season increased starting from 6 - 8 MST, this is thought to be due to the use of various types of synthetic and sustainable pesticides that can affect the diversity of arthropods in rice fields. Therefore, it is necessary to conduct further research on the resistance level of pest arthropods to synthetic pesticides in rice fields.

Abstract

Sungsang II villages are the main shrimp-producing areas located in the waters of the Musi River Estuary and South Bangka, South Sumatra Province. Shrimp are processed into various products, and crackers are the superior product. It's just that as a superior local product, until now there has been no research regarding the supply chain for shrimp crackers. This research aimed to map the supply chain management of processed shrimp cracker products in Sungsang II Villages. The research was carried out using a survey method. Thirty participants made up the entire sample, and the sampling procedure employed was multistage sampling. Data analysis uses mathematical, tabulated, and descriptive methods. The research results show that shrimp cracker processing in the Sungsang area is a household-scale industry. The raw material for shrimp comes from breech waters, and the process of making crackers is traditionally done using human labor; drying still uses sunlight; and packaging is done simply with plastic. The price of shrimp raw materials ranges from IDR 15,000 to IDR 25,000 per kg, and processors can process 20 to 30 kg of shrimp raw materials per day. The selling price for shrimp crackers from retailers to consumers is IDR 50,000 per kg. The shrimp cracker supply chain involves fishermen as suppliers of shrimp raw materials, craftsmen who process shrimp into crackers, collecting traders, retailers, and consumers.

Abstract

Fall Armyworm (Spodoptera frugiperda) is one of the invasive insect species that cause yield loss in corn crops. This pest can attack other crops, such as food crops, vegetables, legumes, and weeds. This research aims to determine the host suitability of S. frugiperda on several types of host plants. The method used was an experimental method with a single-factor completely randomized design (CRD) consisting of four treatments in five replications using four different types of host plants: maize (Zea mays L.), soybean (Glycine max L.), papaya (Carica papaya L.), and chinese kale (Brassica oleraceae var. acephala). The highest percentage of S. frugiperda attack intensity in the choice test was obtained in the treatment with chinese kale leaves (70%) and the lowest in the papaya leaves treatment (20%). In the feeding activity of 3rd instar larvae, the treatment of maize leaves and soybean leaves showed the fastest feeding activity at 11:00 and 12:00, while in the feeding activity of 4th instar larvae, the treatment of maize leaves and chinese kale leaves showed a fast larval feeding activity with a feeding duration of ± 5-10 minutes. Fall Armyworm can also attack other host plants such as soybeans and chinese kale. It can even endure by feeding on papaya leaves, which are typically used as a botanical pesticide. It is essential to step up surveillance against this pest because there are so many additional possible hosts for it.

Abstract

Sungsang I and Sungsang II villages are tidal areas because they are located on the coast and directly adjacent to the Bangka strait. Sungsang I Village and Sungsang II Village are one of the areas that have abundant marine products in Banyuasin II Regency, one of which is shrimp which is then processed by the local community into crackers in the form of a cottage industry. Until now, socioeconomic research on the income and feasibility of shrimp cracker business in this region is still scant. The purpose of this study is to analyze the amount of income of shrimp cracker entrepreneurs in Sungsang I and Sungsang II Villages and their business feasibility. The results of this study showed that the business income of shrimp crackers amounted to Rp. 960,837.67 per production or Rp. 23,899.14 per kilogram of shrimp crackers. While the R/C value obtained from the shrimp cracker business is 1.92 (R/C value > 1), which means that the shrimp cracker business in Sungsang I and Sungsang II Villages is feasible to run.

Abstract

Irrigation is the most important part of plant cultivation to meet the water needs for plant growth and yield. However, irrigation is a common problem in dryland areas. The drip irrigation system is an alternative to solve the problem of water droplets that can improve water use efficiency. One consideration when using drip irrigation is designing the irrigation layout so that the water supply to each plant is uniform. This study evaluated two layout layouts of drip irrigation systems for pok choi plants (Brassica rapa var. chinensis L.) with different planting media. The method used a split-plot design with 2 factors. Variation of drip irrigation system (V) was the main plot which consists of 2 levels, namely variation 1 (V1) and variation 2 (V2). Media type (M) served as a subplot comprised of 3 levels, namely soil (M0), soil+charcoal husk (M1), and soil+cocopeat (M2). The feasibility of these two drip irrigation system designs included drip discharge values, water uniformity coefficient, water distribution uniformity, and storage efficiency. Based on the evaluation of the feasibility of drip irrigation system design, design 1 (V1) gave better values for the average value of drip discharge (0.16 l/minute), uniformity coefficient (99.71%), uniformity of water supply (82.11%), and storage efficiency (73.89 %). The layout of the drip irrigation had a significant effect on the height of pok choi plants on 1 and 2 WAP.
