Abstract

Soil chemical, physical and biological analyses are a crucial but often expensive and time-consuming step in the characterization of soils. Rapid and accurate predictions and relatively simple methods are ideally needed for soil analysis. The objective of this study was to predict some soil properties (e.g. pH, EC, total C, total N,C/N, NH4-N, NO3-N, P, K, clay, silt, and sand and soil microbial biomass carbon) across the Wickepin farm during summer season using a Mid-Infra Red - Partial Least Square (MIR–PLS) method. The 291 soil samples were analyzed bothwith soil extraction procedure and MIR Spectrometer. Calibrations were developed between MIR spectral data and the results of soil extraction procedures. Results using the PLS-MIR showed that MIR-predicted values were almost as highly correlated to the measured value obtained by the soil extraction method of total carbon, total nitrogen and soil pH. Values for EC, NH4-N, NO3-N, C/N, P, K, clay, silt, sand, and soil microbial biomass carbon were not successfully predicted by the MIR – PLS technique. There was a tendency for these factors to correlate with the MIR predicted value, but the correlation values were very low. This study has confirmed that the MIR-PLS method can be used to predict some soil properties based on calibrations of MIR values.Keywords: MIR-Partial Least Square, MIR-Spectroscopy, soil properties

Abstract

Soil fauna has played an important role in ecosystem functioning, especially as ecosystem engineers which contribute to soil fertility in tropical environment.  A tailing deposition area is  one habitat that has several types of soil fauna to live and growth as well as involves in the decomposition of organic matter. The objective of this study was to examine the number and distribution of soil fauna in the tailing area of Freeport Indonesia Mining and Gold Company, Timika.  The study was located in some inactive tailing deposition areas in between Double Levee  of the lowland area of ModADA (Modification Ajkwa Deposition Areas).  Samples were taken from inactive tailing as 198 of ModADA for soil and soil fauna, the Kuadran Method was used  to collecting soil fauna on the soil surface and in the soil.  There were 17 types/ordo of soil fauna in the study area and the highest number was a group of ants (Hymenoptera/Formicidae).  Population density (PD) and relative density (RD) of soil fauna (Formicidae) ranged from 0.03-2.41 Individu m-2 (PD) and 0.07-6.50% (RD).  Both PD and RD were likely to increase as the number of soil fauna increase.  The distribution of most soil fauna were found as a clump, while Pulmonata (Gastropods) were distributed normally in the tailing areas.  The number and types (ordo) of these soil fauna had showed that inactive tailing deposition areas were considered a good habitat for soil fauna.Key words: Distribution, population, soil fauna, tailing[How to Cite: Djuuna IAF. 2013.

Abstract

Low potato production in Ilaga District, Puncak Regency, Papua Province is caused by various factors, namely extreme environmental conditions, less optimal cultivation techniques, low seed quality, and poor soil fertility, so efforts to improve cultivation need to be made. This activity aimed to provide technical guidance and pilot demonstrations on cultivation, how to make organic fertilizers, seed propagation techniques, the introduction of pests, diseases, and their control. The technical guidance was carried out in Kago village, Ilaga District, on November       22-26, 2017. The location is located at an altitude of 2400 m above sea level. Farmers were given instructions on how to cultivate potatoes properly, how to get quality potato seeds on their land, how potato cultivation can be done in sacks when the climate is extreme, especially during the condition of frost and hail, fertilization techniques, and making organic fertilizers and recognizing pests and diseases in the field and their control with organic pesticides. Thirty-one potato farmers followed this activity. The participants showed enthusiasm for increasing potato production through appropriate cultivation. Monitoring of follow-up activities was carried out by extension workers of the local Agriculture Service. The result of the monitoring indicated that there had been improvements in cultivation techniques, organic fertilizer production, and quality potato seeds. Farmers have also recognized several types of pests and diseases and their biological control efforts. Based on the technical guidance, potato productivity increased to 3 tons /ha at the end of 2020. --- Rendahnya produksi kentang di Distrik Ilaga, Kabupaten Puncak, Provinsi Papua disebabkan karena berbagai faktor, diantaranya kondisi lingkungan yang ekstrim (curah hujan  tinggi, hujan dan embun es yang terjadi secara periodik, lama penyinaran matahari pendek pada bulan tertentu), teknik budidaya kurang optimal, kualitas bibit rendah, kesuburan tanah kurang, sehingga perbaikan teknik budidaya perlu dilakukan. Kegiatan ini bertujuan untuk memberikan bimbingan teknis (bimtek) dan demonstrasi plot (demplot) terkait dengan teknik budidaya, pembuatan pupuk organik, teknik perbanyakan benih, pengenalan hama dan penyakit serta teknik pengendaliannya. Kegiatan bimtek dan demplot dilaksanakan di kampung Kago, Distrik Ilaga pada tanggal 22-26 November 2017. Lokasi kegiatan terletak pada ketinggian 2400 m dari permukaan laut. Petani diberikan arahan tentang bagaimana membudidaya kentang dengan benar, bagaimana mendapatkan bibit kentang yang berkualitas di lahan mereka, bagaimana budidaya kentang dapat dilakukan di karung apabila iklim sangat ekstrim terutama ketika musim dingin yang menyebabkan terjadinya frost dan hail, teknik pemupukan dan pembuatan pupuk organik serta pengenalan hama-hama dan penyakit di lapang dan pengendaliannya dengan pestisida nabati. Hasil kegiatan diikuti oleh seluruh petani kentang yang berjumlah 31 orang. Para peserta menunjukkan antusias mereka untuk bagaimana meningkatkan produksi kentang melalui teknik budidaya yang sesuai. Monitoring kegiatan lanjutan budidaya dilaksanakan oleh penyuluh Dinas Pertanian setempat. Hasil dari monitoring ini menunjukkan adanya perbaikan teknik budidya, kemampuan petani dalam membuat pupuk organik, menghasilkan bibit kentang lebih berkualitas dan kemampuan petani mengenali beberapa jenis hama dan penyakit serta pengendaliannya secara alami, yang terindikasi dari meningkatnya produktiftas kentang menjadi 3 ton/ha pada akhir tahun 2020.

Abstract

Penutupan lahan merupakan faktor penting, terutama tutupan lahan di sekitar Daerah Aliran Sungai (DAS). Monitoring terhadap pola perubahan penggunaan lahan di sekitar DAS penting untuk dilakukan sehingga dapat dipahami perubahan dan dampak yang terjadi. Perubahan penutupan lahan yang terjadi di Kabupaten Manokwari adalah dampak dari adanya proses pembangunan infrastruktur dalam memenuhi kebutuhan manusia akan pemanfaatan lahan. Penelitian ini dilakukan di sekitar DAS Pami Kabupaten Manokwari, penelitian ini bertujuan untuk menganalisis pola perubahan penutupan lahan dengan periodik waktu tahun 2009 hingga tahun 2018. Metode yang digunakan dalam penelitian ini adalah Teknik interpretasi peta melalui data citra lahan yang terekam dan analisis deskriptif. Hasil analisis menunjukkan bahwa telah terjadi peningkatan perubahan penggunaan lahan pada kawasan terbangun di DAS PAMI selama tahun 2009-2018 yang disebabkan oleh pertambahan jumlah penduduk sehingga terjadi alih fungsi lahan. Selain itu, kondisi hidrologi menunjukkan bahwa debit aliran di DAS Pami dipengaruhi oleh perilaku hujan yang mempengaruhi kondisi kadar air tanah, tutupan lahan, dan aliran permukaan. Adapun peningkatan besaran air larian (koefisien C) dan debit limpasan (Q) pada DAS Pami seiring dengan terjadinya perubahan tata guna lahan. Tentunya pola penggunaan lahan berpengaruh terhadap perhitungan aliran permukaan yang disebabkan oleh curah hujan.

Abstract

The aims of this research were to study some soil chemical properties, P, K, Fe uptake and sweet potato growth as the result of Crandalitte Extract, Humat Fraction, and Potassium application on Ultisol Warmare. The pot experiment was conducted in the Screen house, Department of Soil Science Faculty of Agriculture, University of Papua Manokwari. The pot experiment has been done using Completed Randomize Design with 7 treatments and four replications , namely: A0 = no fertilizer (treatment); A1 = 100% crandalitte extract + 0% organic fraction + 0% potassium; A2 = 80% crandalitte extract + 10% organic fraction + 10% potassium; A3 = 60% crandalitte extract + 20% organic fraction +2 0% potassium; A4 = 40% crandalitte extract + 30% organic fraction + 30% potassium; A5 = 20% crandalitte extract + 40% organic fraction + 40% potassium, and; A6 = 0% crandalitte extract + 50% organic fraction + 50% potassium. The dosage of each treatment was 100-liter ha-1 (4 g Pot -1). Some soil chemical characteristics were analyzed for pH (H2O), pH (KCl), N-Total, C-organic, P-available, K-total, and Al-exchangeable. P, K, Fe concentrations. The plant growth variables were measured mainly for long steam on 5, 6, 7 and 8 weeks after planting, biomass of trubus, Data were analyzed using statistical analyses of Analysis of Variance (F Test) and DMRT test. The result showed that the application of crandalitte extract, humic fraction and potassium was significantly increased the status of P-available and H-exchangeable, but not affected significantly for other soil chemical characteristics (pH H2O, pH KCl, C-organic percentage, N-total, and Al-exchangeable). Fresh and dry weight of sweet potato trubus were also significantly affected by those application, however it was not affected significantly on long steam; wet weight and dry weight of root and also root length of sweet potato. Among the treatments, the A2 treatment (80% EFC: 10% Organic fraction: 10% Potassium) showed a better value of the status P-available, H-exchangeable and the biomass of trubus. This might be related to the characteristic of acid mineral soil that need high P fertilizer and the balance application of organic matter and potassium.

Abstract

This study aimed to predict the need for lowland rice land, and evaluate the suitability of the land to meet food needs in the West Papua province. This study used a descriptive method with food demand projection techniques to predict the need for lowland rice land; and the technique of matching data on physical characteristics of land with land suitability criteria for lowland rice plants based on the Land Evaluation Technical Manual to evaluate the suitability of lowland rice fields. The projection result showed that the demand for food and land tends to increase every year, therefore, based on the comparison between food needs and the production, the West Papua province tends to experience a food deficit. An alternative to increase rice production is the extensification of paddy fields. The results of the evaluation of actual land suitability for lowland rice in the West Papua province ranged from the suitability class moderately suitable (S2) to marginally suitable (S3), with the limiting factor in the S2 land suitability class were nutrient retention (KB, CEC), available nutrients ( P2O5, N-total) and soil texture; while the limiting factors in the S3 land suitability class were slope, temperature and soil texture. If improvement efforts are made by adding organic matter and fertilization, then the distribution of potential land availability (available and suitable) is spread in very suitable land suitability classes (S1) and quite suitable (S2), with the largest land area being in Teluk Bintuni district.

Abstract

ABSTRACT: Sweet potato (Ipomoea batatas L.) is one of the world's most important food crops with great potential to be developed in Indonesia. This plant is rich in carotenoids and anthocyanins. Anthocyanin compounds in sweet potatoes function as components of healthy food. The purpose of this study was to identify the morphological diversity of sweet potato accessions, cultivation systems, and utilization of local communities in Wanggar District, Nabire Regency. The method used in this research is descriptive method with direct observation techniques in the field, at 3 villages: namely Wiraska, Wanggar Sari, and Karadiri in the Wanggar District, Nabire Regency. Data on sweet potato diversity were analyzed using cluster analysis with the NTSYS version 2.0 program. The result of this research are: (1) At the research sites in the villages of Wanggar Sari, Wiraska, and Karadiri there were 6 cultivars of sweet potato plants based on local names, namely: Unggu, Mokupudugu, Ueta, Mokupudugu, Nota, and Gelakue genotypes. These 6 cultivars had a diversity of morphological characters, (2) Based on the results of the cluster analysis, there are 2 main clusters that have the lowest similarity in morphological characters (34%), namely Cluster I (Unggu and Gelakue) and Cluster II (Makupudugu, Nota, Ueta, Kilumbi). The genotypes of Ungu and Gelakue in Cluster I have similar morphological characters of 43%, (3) Local communities in the Wanggar District still use traditional sweet potato cultivation systems and techniques that have been used from generation to generation, from land clearing to harvesting, and (4) In addition to being used as food, the plant parts of sweet potatoes are also used based on local wisdom communities as traditional medicines and natural fertilizers.

Abstract

Soil fertility status was an important factor that determines the success of corn farming. The five properties used to predict this fertility status are C-Organic, KB, P2O5 – total, K2O – total, and CEC. The combination of the use of organic and inorganic fertilizers aims to improve soil fertility, increase productivity, and soil sustainability. The study used a 2-factor randomized block design. The first factor was the combination of fertilization consisted of 6 levels and the second factor was 2 genotypes of red corn pulut Unipa. The results showed that the soil fertility status at the study site was classified as low with the details of the criteria of C-Organic (Low), KB (High), P2O5 (High), K2O (High), and CEC (Low). There were no interaction in all growth components. The genotype of Anggi Merah Pulut Unipa 3 had better growth than Anggi Merah Pulut Unipa 1.

Abstract

The objective of this study was to determine the number of spores, root colonization and the type of AM Fungi in some agricultural plants in Oransbari District. Soil and root samples were collected across the agricultural land to isolate AM Fungi propagules using wet sieving method and root colonization using gridline method. AM Fungi spores subsequently identified by the Gedermann and Trappe identification manuals, some soil characteristics were also analyzed.  The results showed that the number of spores at each sampling location ranged from 5.0 to 35 spores/50 gr of soil. The highest number of spores is found in the rhizosphere of Lycopersicum esculentum and the lowest is in Oryza sativa. The percentage of roots infected ranged from 15,3 to 76,38%, the highest of infections found in Oryza sativa and the lowest in Capsicum annuum. There were four AM Fungi morphotypes on agricultural soil of Oransbari i.e Glomus, Acaulospora, Scutellospora and Gigaspora.  Soil pH and water content influenced the presence of AM Fungi, while Nitrogen and Phosphorus content did not influence the spore numbers in the soil as well as in the root.  This might be related to the routine and highly use of inorganic fertilizers and pesticides in these areas.
