Abstract

The availability of adequate water is one of the key factors in supporting increased food productivity, especially in areas that have large agricultural potential such as the Warsansom Watershed (DAS), West Papua. This research aims to predict water availability in the Warsansom watershed using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was chosen because of its ability to simulate hydrological processes, erosion and land use dynamics in a spatial-temporal manner. The data used includes rainfall, temperature, topography, soil type and land use patterns. The analysis results show that the average annual rainfall is 322 mm/year, with an annual average temperature of 26.49°C. The Warsansom watershed area is dominated by secondary dryland forest (78.69%) which contributes significantly to groundwater infiltration and recharge. Regional delineation resulted in 33 sub-watersheds with a total area of ??144,280 ha, as well as 273 hydrological response units (HRU) which became the basis for identifying critical areas in water management. SWAT simulations reveal potential risks of surface runoff in areas with steep slopes (36.53%) that require conservation interventions to reduce erosion and sedimentation. This research recommends data-based strategies for optimizing water resource management, including improving irrigation infrastructure, developing cropping patterns that are adaptive to water availability, and mitigating the impacts of climate change. By utilizing SWAT simulations, it is hoped that food productivity in the Warsansom watershed can increase sustainably, supporting food security in the West Papua region

Abstract

Ultisol soil has a high aluminum content and is often attacked by blast disease, which inhibits the growth and production of upland rice plants. This study aims to obtain varieties and lines of upland rice tolerant to aluminum stress and blast disease planted on Ultisol Lampung. The study used a randomized complete block design (RCBD) with 8 types of lines and 4 varieties; The experiment was repeated three times. The results showed that line 2 (PL47)-7 was better than the other lines as indicated by productive tillers of 16.8 stems, flowering age of 50% (72.12 days), number of filled grains per panicle of 75.56 grains, the weight of 100 grains of 2.70 g, yield per harvest plot of 172.51 g/ 10 m2, Aluminum stress has a score of 3 with normal growth indicators, but there are white or yellow spots on the tips of old leaves (20–39%), and neck blast has no symptoms with a score of 0.

Abstract

The presence of weeds in paddy rice crops results in a decrease in yields. Appropriate weed control methods are needed as an effort to reduce potential production losses. The first step to find out the right way to control weeds is by identifying the dominance and diversity of existing weeds. This study aims was to determine the dominance and diversity of weeds in organic and conventional paddy fields. This research was conducted in organic and conventional paddy fields of Lampung State Polytechnic, Lampung Province from October to December 2022. Weeds were observed on the 0.5 m2 quadrant method with 10 replications. The data were analyszed to find the Summed Dominance Ratio (SDR) value to determine the dominant weed and the Shannon - Wiener index (H') value to determine weed diversity. The identification results showed there were 11 weed species in organic land and 7 weed species in conventional land. Broadleaf weeds were the most dominant weeds in both land areas, namely Monochoria vaginalis in organic rice fields and Spenochlea zeylanica in conventional rice fields. The results of the weed diversity index analysis showed that in both land areas fall into the category of moderate diversitywith the value of  2.31 in organic rice fields and 1.93 in conventional rice fields.

Abstract

The presence of weeds can result in a reduction in the productivity of rubber plants, necessitating the implementation of control measures. Among the various control methods, the use of herbicides derived from paraquat dichloride has been identified as a more effective and efficient approach in terms of cost and time. However, the application of weed control measures can lead to alterations in the structure and composition of weeds. The objective of this study was to ascertain the prevalence of weeds and the impact of paraquat dichloride herbicide on the composition of weeds in rubber plantations. This study employed a randomized group design with six treatments and four replications. The treatments consisted of doses of paraquat dichloride, including 310.5 g/ha (P1), 414 g/ha (P2), 496.8 g/ha (P3), 621 g/ha (P4), mechanical control (P5), and control (P6). The results demonstrated that paraquat dichloride herbicide was efficacious in the control of weeds with a rapid onset, yet exhibited a limited duration in comparison to crop-translocated herbicides. This was evidenced by the diversity of weed species dominance at SDR 4 WAA < 8 WAA < 12 WAA. The application of paraquat dichloride herbicide and mechanical control were found to induce alterations in weed composition.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan untuk menjawab permasalahan petani di Desa Kalirejo, Kecamatan Negeri Katon, yang masih bergantung pada pupuk kimia dan belum optimal dalam memanfaatkan limbah pertanian. Penggunaan pupuk kimia yang berlebihan berdampak pada penurunan kesuburan tanah serta meningkatnya biaya produksi. Oleh karena itu, diperlukan inovasi dalam pengolahan limbah pertanian menjadi pupuk organik dengan bantuan teknologi dekomposer. Tujuan kegiatan ini adalah meningkatkan pengetahuan dan keterampilan petani dalam membuat pupuk kompos menggunakan dekomposer agar proses pengomposan menjadi lebih cepat dan efisien. Metode kegiatan meliputi ceramah, diskusi, demonstrasi langsung, serta evaluasi melalui kuesioner pretest dan post-test untuk menilai peningkatan pengetahuan peserta. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada kemampuan dan pemahaman petani terhadap pembuatan pupuk kompos. Nilai rata-rata pretest sebesar 55,2 meningkat menjadi 85,45 pada post-test, atau naik sebesar 30,8 poin (55,8%). Selain itu, efisiensi waktu pembuatan kompos meningkat dari tiga bulan menjadi satu bulan. Petani juga mampu memproduksi pupuk organik secara mandiri sehingga mengurangi biaya dan ketergantungan terhadap pupuk kimia. Kegiatan ini membuktikan bahwa transfer teknologi dekomposer efektif dalam meningkatkan kemandirian dan keberlanjutan usaha tani.

Abstract

The bud chip technique is an important method in sugarcane propagation, as it enables the production of a large number of seedlings while using less planting material. However, the small size of the bud cuttings results in limited nutrient reserves and endogenous hormones, which may constrain early seedling growth. Therefore, optimizing the composition of the growing media and applying plant growth regulators (PGRs) are necessary to enhance seedling growth and development.This study employed a factorial Randomized Complete Block Design (RCBD). The objectives were to determine: (1) the appropriate composition of growing media for sugarcane seedlings using the bud chip technique; (2) the effects of different concentrations of plant growth regulators (PGRs) on seedling growth; and (3) the interaction between growing media composition and PGR concentration on the growth of sugarcane seedlings. The results indicated that: (1) the use of topsoil combined with cow manure, as well as topsoil combined with cow manure and rice husk compost, resulted in comparable seedling growth, both of which were superior to the control, as reflected in shoot height, leaf number, and shoot-to-root ratio. However, no significant differences were observed among treatments in terms of time to 50% sprouting and growth percentage; (2) different concentrations of PGRs did not significantly affect seedling growth across all observed variables; and (3) no interaction was found between growing media composition and PGR concentration on sugarcane seedling growth.
