Abstract.

Molecular identification of rhizospheric Actinomycetes from karst ecosystems of Gorontalo, Indonesia, and its seed germination induction capability of Zea mays var. doti. Biodiversitas 25: 4763-4771. Karst, as an extreme ecosystem, was a source of diverse Actinomycetes with varied biological activities. This study explored the plant-growth-promoting potential of rhizospheric Actinomycetes from the karst ecosystem of Gorontalo, with a focus on inducing seed germination in Zea mays var. doti. Four locations in Gorontalo were selected to explore Actinomycetes, targeting approximately 20 different rhizospheric plant species to isolate these microorganisms. Among the 25 isolates obtained, representing diverse morphological types from 12 rhizospheric plants, eight actinomycete isolates exhibited phosphate-solubilizing activity and produced indole-3-acetic acid (IAA). The 16S rRNA gene sequence analysis showed that approximately 75% of the isolates belonged to the Streptomyces genus, including Streptomyces cavourensis strain KRZm-02, Streptomyces sp. strain KRZm-03, Streptomyces pratensis strain KRLl-01, Streptomyces carpaticus strain KRIt-01, Streptomyces sp. strain KRIt-02, and Streptomyces aquilus strain KRPa-01. Additionally, 12.5% of the isolates were identified as Nocardiopsis alba strain KRZm-01 and Micromonospora sp. strain KRPt-01, respectively. The two isolates with the highest plant-growth-promoting potential, Streptomyces pratensis strain KRLl-01 and Streptomyces carpaticus strain KRIt-01, were further tested for their ability to promote germination of Zea mays var. doti seeds over 7 days. Among the two, Streptomyces carpaticus strain KRIt-01 exhibited the highest germination-inducing potential. Overall, the karst ecosystem of Gorontalo offers a valuable reservoir of biological resources with the potential for Plant-Growth-Promoting Rhizobacteria (PGPR). Further studies on the application of these actinomycete isolates as biofertilizers in agricultural and plantation crops could significantly contribute to improving crop growth and productivity, thereby revolutionizing agricultural practices.

Abstract

Background: The complexity of the distribution patterns of drought and soil water balance across various regions raises questions about how the mechanism of drought events responds to climate anomalies. The research aims to determine the climate anomaly pattern of maize drought levels based on land water balance with FAO Penman Monteith evapotranspiration value estimates in Gorontalo district, Indonesia. This research was carried out from April to August 2020.

Methods: The research location was in Limboto subdistrict, Gorontalo Province, Indonesia. The material in this research is climate data from 1997 to 2016 (20 years) including rainfall, solar radiation, maximum and minimum air temperature, exposure time, air humidity and wind speed. The tools in this research are sample rings, Belgi drills, GPS, documentation tools. The method used is the drought index analysis method and the water adequacy index based on the FAO Penman Monteith evapotranspiration method.

Result: El Nino and La Nina climate anomaly patterns occur every 5 to 7 year recurring period. The highest level of drought with strong drought status occurred during the El Nino anomaly in 1997-1998 for 8 months and this triggered a decrease in harvested area and corn production with a coefficient of reduction in vulnerable production category. La Niña climate anomaly years 1999 and 2007 had an impact on low accumulation potential of water loss with highest level of drought weak status and this triggered an increase in harvested area and corn production with a coefficient of reduction in very resistant production category.

Abstract

Grafting has become a technique with high potential for increasing the efficiency of modern and intelligent crop cultivation, and shows its adoption of power and robustness under different inspection situations. This study aims to determine impact of interaction between scions length and cover type on the success of durian grafting. It was carried out using a Split Plot Design method, with the main plot being the cover type composed of individual and mass of cover type, while the subplot consists of 10 and 20 cm scions length. The observed variable were time of bud emergence, percentage of bud emergence, bud length, leaves of number and grafting of success. The data were analyzed by Analysis of Variance (ANOVA). If there are significantly different treatments then proceed with the Least Significant Difference test at 5% level. The results showed that the interaction between scions of length and cover type treatment did not affect grafting technique. However, the treatment of cover type affected the percentage of bud emergence, bud length, leaves of number, and grafting success. The treatment of scions of length also affected the leaves of number. The mass cover type resulted in 93.5% bud emergence, 1.5 cm bud length, 2.73 increase in the leaves of number, and 93% grafting success. Meanwhile, the treatment of scions of length 20 cm increased the leaves of number by 2.13 strands. Scions of length that is successfully connected to grow and form new shoots has an impact on the development of healthy stems. The cover type in this study was able to protect grafting plants from direct exposure to sunlight, maintain plant moisture, prevent pests and diseases, protect from rain so that grafting can be successful.

Abstract

Porang is becoming recognized as a strategic commodity due to its high demand and substantial economic value. However, the lack of a standardized set of site-specific land suitability criteria for porang presents challenges in conducting land suitability assessments and planning for its use. Therefore, this study addressed the knowledge gap by evaluating land suitability classes and the implications of land management for porang cultivation, using different parametric methods. A comprehensive survey of 32 land units was conducted, followed by soil analysis in the laboratory. The square root (SRM) and the Rabia and Terribile (RTM) parametric methods were employed for the land suitability assessment. Subsequently, the land management priorities were determined based on the results of the land suitability class analysis derived from both methods. The results showed that land suitability for porang plants with SRM and RTM was dominated by the very suitable class (S1), however, the distribution of S1 was wider with RTM. The remaining classes with SRM consisted of moderately suitable (S2), marginally suitable (S3), currently not suitable (N1), and permanently not suitable (N2), while the remaining classes with RTM only consisted of S1, S2, and S3 classes without class N. The priority of land management for porang plants for both parametric methods is dominated by priority I, however, in SRM there are priorities II, III, and NP (not priority), while in RTM, there are only II and III. Based on land suitability class and land management priority, RTM was still better than SRM.

AbstractLactuca sativa L. has good economic prospects, but lettuce production often declines due to the unmet water requirement of lettuce. This study aimed to determine the water needs of lettuce on Inceptisol and Vertisol based on the Internet of Things (IoT). The location study was in the green house, Huluduotamo Village, Bone Bolango Regency, from September to October 2021, while the Vertisol and Inceptisol samples were from Sidomukti Village, Gorontalo Regency. This study used the Penman method with the Cropwat 8.0 application which was integrated with a smartphone through the Blynk (IoT) application. The water requirement yield of lettuce plants in September on Vertisol and Inceptisol in the early phase was 2.45 mm/day, the middle phase was 3.73 mm/day, and the final phase was 3.54 mm/day. Soil moisture detection device at field capacity moisture content produces 319 Analog Digital Converter (ADC) and soil in moist conditions reaches 534 ADC. The analog data value of the water content of the Inceptisol field capacity is 343 ADC and the soil in a moist state is 574 ADC. The performance of the device for detecting soil moisture in the water condition of the 15% field capacity of Vertisol and 22% Inceptisol is more effective than the gravimetric method.

Target penurunan emisi GRK Indonesia dengan kemampuan sendiri pada Updated NDC (UNDC) sebesar 29% meningkat ke 31,89% pada ENDC, sedangkan target dengan dukungan internasional pada UNDC sebesar 41% meningkat ke 43,20% pada ENDC. Upaya mitigasi difokuskan pada sektor pertanian dan kehutanan sebagai sumber mekanisme carbon sink, pencegahan deforestasi dan degdrasi hutan. Pelaksanaan kegiatan pengabdian KKN MBKM di desa Bintalahe Kecamatan Kabila Bone, Kabupaten Bone Bolango Propinsi Gorontalo berlangsung pada bulan Mei hingga Agustus 2023. Jumlah mahasiswa yang terlibat berjumlah 11 mahasiswa dari program studi Agroteknologi Faperta UNG dibawah bimbingan 3 dosen pembimbing lapangan. Metode yang digunakan dalam pengabdian ini berupa pelatihan yang bersifat partisipatif kegiatannya berupa penyuluhan, pelatihan, dan bimbingan teknis. Bentuk program yang dilaksanakan meliputi program mitigasi iklim sektor pertanian berupa kegiatan pembuatan biopori dan biopestisida. Program mitigasi iklim sektor kehutanan berupa kegiatan agroforestri. Hasil yang dicapai berupa teknik biopori yang dilaksanakan bermanfaat bagi kondisi lingkungan setempat dengan indikasi minimnya genangan air serta tanah di pekarangan petani tidak mudah mengalami kekeringan. Biopestisida yang dihasilkan mampu dibuat secara mandiri oleh masyarakat karena bahan baku yang mudah diperoleh serta teknik pembuatan maupun aplikasi ke tanaman bisa diaplikasikan secara langsung. Sistem agroforestri ketapang dan cabe mampu meningkatkan potensi hasil cabe walaupun dengan skala rumah tangga yang ke depannya untuk kebutuhan lumbung hidup masyarakat setempat. Terselenggaranya aksi mitigasi iklim di sektor pertanian dan kehutanan di desa Bintalahe ini menjadi standar untuk pengembangan kegiatan aksi mitigasi iklim tingkat tapak.

Abstract

Indonesia berada pada peringkat 9 dari 10 negara yang paling rentan terhadap ancaman keamanan pangan akibat dampak perubahan iklim. Temuan ilmiah terbaru mengenai dampak perubahan iklim di lautan, seperti pemanasan laut, pengasaman, deoksigenasi, kenaikan permukaan air laut dan meningkatnya aktivitas badai, serta bagaimana dampak ini membuat orang lebih rentan terhadap migrasi dan pemindahan. Upaya program Blue Carbon dan Blue Economy dapat terintegrasi dengan kegiatan pengelolaan lingkungan yang telah dilaksanakan masyarakat di tingkat lokal dengan memperhatikan faktor risiko iklim dan dampak perubahan iklim yang mungkin terjadi. Tempat pelaksanaan KKN Tematik UNG ini di desa Panca Karsa 2 kecamatan Taluditi kabupaten Pohuwato propinsi Gorontalo. Waktu pelaksanaan mulai 3 September 2020 hingga 18 Oktober 2020. Jumlah mahasiswa yang terlibat dalam kegiatan KKN tematik ini berjumlah 29 mahasiswa dari berbagai program studi yang ada di UNG yang dibawah bimbingan 3 dosen pembimbing lapangan. Bentuk program yang akan dilaksanakan oleh peserta KKN adalah pelatihan dan pembinaan meliputi Program Blue Carbon seperti restorasi dan pelestarian ekosistem mangrove, penanaman dan pelestarian ekosistem lamun sedang Program Blue Economy seperti teknik hidroponik dari sampah plastik dan teknik vertikultur. Hasil yang dicapai dari program KKN Tematik UNG 2020 ini yakni penerapan program Blue Economy dibutuhkan guna peningkatan ketahanan ekonomi masyarakat dengan total keuntungan program sebesar Rp 4.975.000. Program hidroponik dan vertikultur berperan dalam memacu semangat masyarakat dalam mengefektifkan dan mengurangi sampah plastik yang nantinya banyak digunakan untuk teknologi hidroponik dan vertiultur. Terukurnya potensi dan kontribusi masyarakat desa melalui aksi-aksi lokal yang spesifik dalam hal upaya mitigasi iklim.
