Sosialisasi Anti Narkoba Sebagai Bentuk Pencegahan Penyalahgunaan Dikalangan Remaja Smp Negeri 1 Kampa Desa Sawah Baru

Real work lecture (KUKERTA) is a form of community service carried out by students in overcoming village problems that are still unresolved. This service is in the form of socialization to provide information about the dangers of drugs. The rise of drug abuse among teenagers is our main reason for socializing in one of the educational institutions in Sawah Baru Village, namely SMP Negeri 1 Kampa. Teenagers who are still unstable in making decisions are the right targets to become drug users. High curiosity is also one of the factors that teenagers fall into this crime. So that anti-drug socialization must always be promoted to the community, especially teenagers as the next generation of the nation. The purpose of this anti-drug socialization is to provide understanding, direction, and warnings related to drugs that can threaten the lives of both individuals and social.

Systematic selection to adaptive doubled haploid rice lines under different environments of submergence screening methods

Climate change can trigger submergence stress, which has an impact on decreasing rice yield and causing crop failure. This needs to be overcome with a sustainable approach, such as breeding doubled-haploid (DH) rice varieties that are adaptive to these stresses. However, it requires a systematic screening approach to solve it. Therefore, this study aimed to select DH rice lines that are tolerant and adaptive through systematic submergence screening and their stability; (2) to identify the effectiveness of both submergence screening environments. The study was carried out in three locations: the greenhouse of ICRR-Muara Bogor, the ICRR-Sukamandi Field Experimental Station, and the IPB-Sawah Baru Experimental Station. The first experiment was conducted in ICRR-Muara using a randomized complete block design (RCBD), with genotype as a factor, consisting of 56 doubled-haploid lines, four commercial varieties, and two check varieties (tolerant and sensitive). Seven selected genotypes representing tolerant, moderate, sensitive, and check groups were transferred into pots in Sawah Baru Experimental Station to be evaluated for agronomic and tolerance responses using the RCBD split-plot design. The second experiment was carried out to validate the stability of tolerance traits in doubled-haploid lines. The trial and the process of the second experiment were like the first experiment (clear water). However, the submergence in the second experiment was conducted using muddy water. The experimental results showed that the screening of concrete pools was effective in determining sensitive lines in large populations. Meanwhile, screening in the pond with muddy water was better in identifying the effect of submergence stress on agronomic and yield characteristics. Based on screening, F13, F14, F15, and F19 are adaptive doubled haploid lines under the systematic screening of submergence stress and have been evaluated for their adaptive and tolerance stability. Therefore, they can be recommended for preliminary yield tests.

Respons Hasil Padi dan Hara Tanah Sawah terhadap Bakteri Pelarut Fosfat dan Pemfiksasi Nitrogen

The condition of unfertile paddy field due to excessive inorganic fertilizer application causing soil degradation. Fertilizing techniques using phosphate solubilizing and nitrogen fixer bacteria are breakthroughs that should be developed in paddy cultivation to increase fertility soil and harvest of rice. This research aims to study on phosphate solubilizing and nitrogen fixer bacteria ability to increase the harvest of rice by increasing chemical and biological fertility of soil. The research was conducted in the greenhouse of Sawah Baru experimental garden, IPB University. The design used was a completely randomized design with one factor that was dosage of inorganic fertilizers (NPK) with seven levels that were control, NPK 100%, NPK 0% + bacteria, NPK 25% + bacteria, NPK 50% + bacteria, NPK 75% + bacteria and NPK 100% + bacteria. Each stage was repeated four times, so there were 28 units. The results of phosphate solubilizing and nitrogen fixer bacteria could produce more rice grain 0.32 ton.ha<sup>-1</sup> than NPK 100% (recommended dose). Biological soil fertility improved with the increased population of bacteria, but there was no improved soil chemical fertility of soil.

THE LEAF GREENNESS AND YIELD COMPONENTS OF PADDY PLANTS INFLUENCED BY BIOLOGICAL FERTILIZER WITH AND WITHOUT COMBINATION OF INORGANIC FERTILIZERS

The use of biological fertilizer seems to be most important in creating environments for sustainable agriculture. This fertilizer is made up of living bacteria cells which depending on the soil conditions, are able to reproduce. In soil these bacteria have the greatest benefits for agricultural crops. They can increase the level of nitrogen in soil after converting the atmospheric nitrogen. Other species of these bacteria increase the availability of essential nutrient, Phosphorous. However, the availability of these two essential nutrients (nitrogen and phosphorous) in the soil is one factor in plant growth and yields. The second important factor is the ability of the roots to absorb these nutrients. In this aspect, the volume and type of roots of the respective plant also contribute significantly to plants growth as well as provision of expected yields. This study was carried on from September to December, 2018 at Sawah Baru, Bogor Agricultural University. The objectives were to observe the influence of biological fertilizer with and without combination of NPK and Urea fertilizers to enable rice plants to attain leaf green level which could produce expected paddy yields. The interaction effect between fertilizer treatments and the paddy varieties was also observed. Experiment design was two factor treatments arranged in a split plot. Fertilizer as main plot and paddy varieties as sub-plot laid in a Completely Randomized Block Design in 3 replications. The results showed significant differences in leaf green conditions and 1,000 grains weight of paddy.

The reduction in agricultural land due to land conversion has encouraged several technological innovations in cultivation systems, including intercropping planting patterns. The study aimed to study various intercropping patterns with several varieties of maize which can increase production. The research was conducted at the Sawah Baru Experimental Station of the IPB University, Darmaga, Bogor, from November 2018 to February 2019 using a split-plot design with three replications. The main plot was the cropping systems, consisting of monoculture, single-row intercropping, double-rows intercropping, and triple-rows intercropping. The subplot was the maize varieties, consisting of Sukmaraga, Bima 19, and BISI 2. Regression and correlation analyses were carried out to determine the relationship between microclimate and productivity. The results showed that the productivity of maize and soybean was affected by the interaction between cropping patterns and varieties. The highest productivity of maize was obtained from the intercropping pattern of double rows of BISI 2 maize (7.33 ton ha-1), while the lowest maize productivity was in the intercropping pattern of a single row of Bima 19 maize (2.93 ton ha-1). The highest productivity of soybean was obtained from the intercropping cropping pattern of a single row of BISI 2 maize. The effect of microclimate on various cropping patterns with productivity in this study was a little. Land equivalent ratios (LER) in all treatments were greater than 1 except for intercropping 1 row of Bima 19 maize, indicating that intercropping can increase land productivity.

Pendidikan Antikorupsi Kepada Siswa Sekolah Dasar Dengan Metode Storytelling

The level of corruption in Indonesia has not decreased significantly even though there have been severe criminal penalties and prevention systems carried out. It is considered that the behavior of corruption is taken root in the mentality of the Indonesian people. Therefore, anti-corruption education needs to be provided early to reduce the possibility of someone to commit corruption when they are adults. The right education method can provide significant results in achieving educational goals to be achieved. The Community Service Team of the Communication Science and Psychology Study Program at Universitas Pembangunan Jaya held an anti-corruption education for elementary school students in collaboration with Sawah Baru Elementary School. The target of this program is elementary school students in grades 3, 4 and 5. In this anti-corruption education, the team used storytelling methods to facilitate and increase understanding in participant's mind. It turns out that this storytelling method has a large impact on the understanding of corruption in the view of elementary school students. In the future, we hope anticorruption education can be held in every school or into the education curriculum.

 A study was conducted to determine the optimum rates of N, P, K fertilizers on “IPB 9G” upland rice variety from March to July 2018 at the Sawah Baru Experimental Field of IPB University, West Java, Indonesia. Three paralel experiments were carried out in a randomized complete block design to test five fertilizing levels, i.e. 0, 50, 100, 150 and 200% of the reference rate. The reference rates of fertilizer application are 100% N = 200 kg Urea ha-1, 100% P = 100 kg SP36 ha-1, and 100% K = 100 kg KCl ha-1. The applied fertilizers were Urea (46% N), SP36 (36% P2O5) and KCl (60% K2O). Fertilizers were applied three times, 40% at planting, 30% at 4 WAP and the rest 30% at 8 WAP; 100% P and 100% K were applied at planting. Increasing N fertilizer from 0 to 200% of the reference rate increased plant height, dry weight biomass at heading and at harvest, number of productive tillers, harvest index, and grain weight per clump. P increased dry weight of the above ground biomass, whereas K fertilizer increased the leaf area, canopy dry weight, number of grain per panicle, panicle length, harvest index and grain weight per clump. The optimum rate of N and P were 107.09 kg Urea ha-1 and 63.3 kg P2O5 kg.ha-1, respectively, whereas the optimal rate for K fertilizer for “IPB 9G” could not be determined with this study.

Maize is an important crop in Indonesia that is utilized for food, feed, and industry. Waterlogging is one of the abioticstresses challenging maize production in recent years due to climate changes. Vegetative-phase screening methods may benefitplant breeding programs because potential genotypes can be identified at earlier stage with lower cost. This study consistedof two experiments. The first experiment was carried out at the Sawah Baru experimental station of Bogor AgriculturalUniversity (IPB), Bogor, from June to September 2017 using an alpha lattice design with three replications and four blockswithin each replication. The second experiment conducted in a greenhouse at Cikabayan experimental station of IPB, Bogor,from December 2017 to January 2018 using a randomized complete block design with three replications. Genetic materialused were 21 maize genotypes from the Indonesia Cereal Research Institute (ICERI) and IPB, including 19 hybrids and 2inbred lines. The results showed that the dry root weight under normal conditions had significant positive correlation withgrain yield under waterlogging stress, and therefore is potential for early screening. Adaptive genotypes in waterloggingstress selected based on dry root weight are DKLx30, DKLx11, MGoldx37, MGOldx41, and IPB L15-1xMR14. Predictedmean yield across these genotypes was 0.57 ton ha-1 higher yield than the overall mean in waterlogging stress condition.Selected hybrids can be further evaluated for variety release.

Growth and Yield of Kalimantan Landrace Rice and “IPB 8G” as Affected by Dose and Time of Application of Nitrogen Fertilizer

The study aimed to determine the effect of nitrogen fertilizer dose and the frequency of application on the growth and production of landrace rice Kalimantan and a new rice cultivar "IPB 8G". The study was conducted in December 2017 until June 2018 at the Sawah Baru Experimental Field, Bogor Agricultural University, West Java, Indonesia. The experimental design was a split-split plot consisting of three treatment factors, i.e. rice cultivars (main plots), fertilization time (sub-plots) and fertilizing doses (sub-plots). The three rice cultivars used in this trial were local cultivars "Mayas" and "Samarinda", and a newly developed rice cultivar "IPB 8G". The application rates of Nitrogen were 0, 75, and 150 kg N.ha-1 applied at different phases of rice growth: 50% N dose was applied at planting, 25% N dose at the vegetative phase, and 25% at the primordial phase. The different rates of N fertilizer were applied four times, 40% at planting, 20% during the vegetative phase, 20% at the primordial phase, and 20% at heading. Each treatment consisted of three replications totalling 54 experimental units. The N fertilizer application gave a significant effect on all growth parameters except for the harvest index. Time of fertilization significantly affected rice panicle number per hill and harvest index. There were significant differences in the growth of the three rice cultivars, except for the number of tillers. Rice crops fertilized three times with a dose of 75 kg N.ha-1 had the highest number of tillers at 5 week after planting, but it was not significantly different from N at 150 kg.ha-1. The highest grain yield of 2.9 t.ha-1 was obtained from "IPB 8G" cultivar fertilized with 75 kg.ha-1 of nitrogen.

Mekanisme Morfologi dan Fisiologi Tanaman Padi pada Kondisi Rebah dan Strategi Adaptasinya

Extreme weather incident refers to high rainfall and strong winds have been speculated detriment on rice production. However, study on morphological and physiological mechanism, and its adaptation strategy on lodging are rarely reported. Thus, three experiments were conducted in Sawah Baru, Leuwikopo, and Lampung Province, Indonesia from January 2016 to June 2017. The results showed that extreme weather caused rice plant lodged on research area of 27.6% with production loss up to 11.89%. Morphology and physiological adaptations seemed important aspect in responses to extreme weather treatment. Biochemistry composition changed after lodging, especially fatty acid, terpene, alkane, and steroid. Lodging increased total biochemistry compound more than 48% of normal plant. Unlike marked production loss in the plot experiment, in the field, impact of extreme weather on reduction of rice production in Lampung Province was low, 1.03%. Shifting on rice production among agroclimates, minimized the impact of the extreme weather. It is likely that local ability to maintain annual production improvement by more than 5% through expansion of irrigated land, high yielding varieties and inputs subsidies were important factor as local strategy to adapt to extreme weather incident in Lampung.
