Abstract

Most of Kampung Padang resident is a farmer especially as a oil palm and rubber farmer. In the cultivation of oil palm and rubber, there are still a few villagers from Kampung Padang who plant Mucuna between plants as a ground cover crop or Legume Cover Crop, even though Mucuna has many benefits, especially for suppressing weed growth and improving soil chemical properties. The difficulty of obtaining seeds makes people rarely use Mucuna. Some techniques that can be done to induce flowering in plants are using a growth regulator (ZPT) paclobutrazol. Several research results regarding the use of paclobutrazol have succeeded in shortening the length of plant tendrils. Other techniques that can be used to induce flowering in plants are providing water stress, ringing the plants, and pruning the roots of the plants. The response from the people of the Padang village population was very enthusiastic, seen from the many people who asked questions during the event.

Abstract

The primary need for cooking oil or edible oil, the demand for cooking oil raw materials increases from year to year, this increase forces producers of crude palm oil (CPO) to compete to produce quality CPO products. PT. Sinar Pandawa, which is located in the Sennah plantation village, Batang downstream district, Labuhan Batu district, is one of the companies that produce CPO. Therefore, this study aims to determine the quality of CPO PT. Sinar Pandawa has good quality by using an analysis process of free fatty acid levels, namely the amount of free fatty acids resulting from hydrolysis and fat oxidation reactions, water content, namely the amount of water content in CPO and levels of impurities are foreign substances that do not dissolve. The method used in this research is titration using 0.1 NaOH solution for analysis of free fatty acid levels. The oven is open for moisture analysis i.e. heating the sample until the remaining water evaporates. Gravimetry for analysis of impurities content by filtering the sample using Whatman filter paper. The results show that the quality of CPO at PT. Sinar Pandawa which has the highest levels of fatty acids at 5.08%, water content of 0.35% and dirt content of 0.034%. The results of the analysis that has been carried out stated that the quality of CPO PT. Sinar Pandawa has not met the quality standards of SNI. The high value of each parameter, namely free fatty acid content, water content and dirt content with test values in accordance with SNI-2901-2006 maximum free fatty acid content of 5%, 0.25% water content and 0.25% dirt content indicates a lack of quality. CPO produced by PT. Sinar Pandawa due to lack of quality control

Abstract

Corn (Zea mays L.) is a vital food ingredient that plays a significant role in food security in Indonesia, particularly in North Sumatra, and it has considerable potential for developing local corn varieties. This study aims to evaluate the effect of NPK Mutiara fertilizer on the growth of gamma-irradiated local corn (Zea mays L.) plants from North Sumatra. The research was conducted in Perbaungan Village, Bilah Hulu District, Labuhanbatu Regency, North Sumatra Province, from December to February. A completely randomized design (CRD) was employed, featuring one factor and five fertilizer dose treatments: control, 3 g/polybag, 6 g/polybag, 9 g/polybag, and 12 g/polybag, with four replications. The parameters observed included plant height, number of leaves, and stem diameter at 2, 4, 6, and 8 weeks after planting (WAP). The results showed that the application of NPK Mutiara fertilizer significantly affected plant height and the number of leaves at all ages of the plants. The treatment with the highest dose, 12 gr/polybag, produced the best results, with plant height reaching 160.70 cm at 8 WAP, leaves reaching 11.50 leaves, and stem diameter reaching 2.24 cm. NPK Mutiara fertilizer improved the growth of gamma-irradiated corn plants, with higher doses resulting in optimal growth. However, it is essential to apply the correct dosage to avoid harming the plants. This study recommends fertilization with the appropriate dose to optimize corn plant growth in North Sumatra.

Abstract

Rice (Oryza sativa L.) is a strategic food commodity and a primary source of carbohydrates for most of the world's population, including Indonesia. One effort to increase rice production is through mutation.The purpose of this study is to study the influencegamma ray irradiation on several rice varieties at the germination seedling phase. Gamma ray irradiation was carried out in January 2025 at the Center for Isotope and Radiation Applications (PAIR), National Nuclear Energy Agency (BATAN), Pasar Jumat, Jakarta, while planting was carried out on Jl. Belibis, Rantau Selatan District, Labuhanbatu Regency in March 2025. The study used a non-factorial Completely Randomized Design (CRD) namely gamma ray irradiation at the following doses: 0 Gy (control/no radiation dose); 50 Gy; 100 Gy; 150 Gy; 200 Gy; 250 Gy; 300 Gy; 350 Gy; 400 Gy and 450 Gy.Observations were made on germination rate, seedling height, and root length. The data were analyzed using analysis of variance followed by Duncan's multiple range test (DMRT). The results showed a visible effect of gamma ray irradiation on germination rate. Gamma ray irradiation also affected average seedling height and root length.The lowest reduction in germination and seedling height occurred in the Sibenang rice variety at a dose of 450 Gy, at 0%. Meanwhile, the shortest root length was in the Ciherang rice variety at a dose of 450 Gy, at 1.93 cm.

Abstract

Leunca (Solanum nigrum L. ) is one of the indigenous vegetables in Indonesia. The fruit of this vegetable is green and has bitter taste because of its tannin content. The objectives of this study were to get lethal dose 50 (LD50), diversity and to obtain candidates of mutant plants with high and low tannin content in young fruit and ripe fruit in leunca. The research was conducted at Pasir Kuda experimental station, Bogor; National Nuclear Energy Agency (BATAN), Jakarta; and postharvest laboratory of the Center for Tropical Horticulture Studies (PKHT IPB), Bogor, from December 2016 to July 2017. Leunca accession of SN 20 and SN 29 were irradiated using doses of 0, 100, 150, 200, and 250 Gy of gamma ray. The LD50 values for SN 20 and SN 29 were 171.944 Gy and 190.949 Gy, respectively. The analysis of tannin content was performed based on permanganate method by titration using potassium permanganate. The results showed that the highest tannin content of green stage fruit was found in SN20D3.5 with 200 Gy dose and the lowest was found in SN29D1.5 with 100 Gy dose. The highest tannin content of ripe fruit was found in SN20D4.6 with dose of 250 Gy and the lowest was found in SN20D3.1 with dose of 200 Gy. Recommended tannin content for leunca is the low tannin content.Keywords: diversity, gamma ray, indigenous vegetable, irradiation, LD50
