Abstract

Petugas pengendali organisme pengganggu tumbuhan (OPT) pegawai negri sipil memiliki tugas pokok dan fungsi melakukan pengamatan, pengendalian OPT dan dampak perubahan iklim. Provinsi Jawa Barat hanya memiliki 122 orang petugas pengendali organisme pengganggu tumbuhan pegawai negri sipil, 123 orang petugas pengendali organisme pengganggu tumbuhan tenaga harian lepas yang membawahi 626 kecamatan. Jumlah tersebut setiap tahunnya akan terus berkurang, sehingga wilayah pengamatan setiap petugas akan menjadi lebih luas yang berakibat menurunnya tingkat efisiensi, akurasi, dan efektivitas pengamatan di lapangan. Penelitian ini bertujuan mengevaluasi kinerja petugas POPT di era digital saat ini dalam melakukan pengamatan dan peramalan OPT. Metode penelitian yang digunakan adalah metode penentuan responden berdasarkan teknik purposive sampling, responden merupakan petugas POPT dengan jumlah 30 petugas. Hasil wawancara dianalisis secara deskriptif melalui metode Analytical Hierarchy Process (AHP) menggunakan software Expert Choice. Hasil penelitian menunjukkan bahwa keberadaan Petugas pengendali organisme pengganggu tumbuhan di Kabupaten Subang saat ini didominasi petugas yang berumur 21-30 tahun, pendidikan SMK/SMA dan S1, rata-rata pengalaman 5-10 tahun, dan status jabatan fungsional terbesar pada tenaga harian lepas. Analisis AHP menunjukkan kinerja petugas dipengaruhi oleh tiga faktor dengan rasio konsistensinya 0,02, yaitu pelaporan dengan bobot prioritas 16%, fasilitas 15,6%, dan pengalaman 13,4%.

Abstract

This study aimed to determine phosphate fertilizer and mycorrhiza dosages as well as the interaction of both treatments to the physiological character and the yield of ciplukan plants. The experiment was carried out from February to July 2020 on an experimental farm. The study used a Randomized Completely Block Design, consisted of two factors. The first factor was the dose of SP-36 fertilizer, containing 36% phosphate (P2O5), and the levels were P0 = 0% dose (0 kg/ha), P1 = 25% dose (75 kg/ha), P2 = 50% dose (150 kg/ha), and P3 = 100% dose (300 kg/ha). The second factor was the mycorrhizal dose, namely M0 = 0 g, M1 = 3 g, M2 = 6 g, and M3 = 9 g (containing 10 spores per 3 g). Each treatment combination was in triplicates. The measurement and observation data were analyzed using the analysis of variance (F-test), followed by Duncan's multiple range test with P-value = 0.05 and regression. The results showed that application of 75 kg/ha dose was equivalent to the application of 300 kg/ha. P uptakes at 75 kg/ha and 300 kg/ha dose of fertilizer were 22,03 ppm and 23,18 ppm, respectively. The plant growth rate was 12,39 g/cm2/week on the application of 75 kg/ha fertilizer and resulted in 14,24 g/cm2/week on 300 kg/ha dose. The mycorrhiza application was significantly different from the root infection at a dose of 6 g, namely 49.177%. There was an interaction between the dose of SP-36 fertilizer and the mycorrhiza on leaf chlorophyll content at a dose of 0% and 3 g mycorrhiza. Keywords: Physalis angulata, mychorrhiza, phospate fertilizer, physiological character and yield

Abstract

Codot coffee from Tanggamus, Lampung is one of Indonesian specialty coffee with a very limited production. In this research, an authentication study for the Codot ground roasted coffee was conducted using UV-vis spectroscopy and chemometrics. A total of 330 samples of pure and adulterated Codot coffee was prepared. The adulterated Codot coffee samples were intentionally created by adding a regular coffee (non-Codot coffee) into pure Codot coffee samples with three levels of adulterations: low (10-20%), medium (30-40%), and high level (50-60%). All samples were 0,29 mm in particle size. The extraction procedure was performed with hot distilled water (98°C). The spectral data of coffee samples were acquired using a benchtop UV-visible spectrometer in the range of 190-1100 nm using a transmittance mode. The result showed that the pure and adulterated samples could be discriminated along PC1 and PC2 axis. The classification model was developed using LDA with 90,91% of accuracy could be obtained. The LDA model was used to classify the new samples and resulted in a sensitivity (SEN) of 100%, specificity (SPEC) of 76,67%, precision (PREC) of 78,13%, and accuracy (ACC) of 87,27% could be obtained. Using PLS regression, a PLS model was developed to quantify the percentages of Codot coffee adulteration and resulted in high of coefficient of determination both in calibration and validation (R2kal = 0,99 and R2val = 0,98). These results showed that UV-vis spectroscopy and chemometrics are suitable for authentication of Codot specialty coffee with RMSEP = 2,68% and RPD in prediction of 6,49. Keywords: authentication, LDA, PCA, PLS regression, UV-vis spectroscopy

Abstract

Low nitrogen efficiency is one of the sources of greenhouse gas (GHG) emissions from rice fields. Methane (CH4) and nitrous oxide (N2O) emissions could be controlled by nitrification inhibitors (NI). However, NI that has been commercialized is expensive. Therefore, some natural materials should be developed as NI that is low cost, easy to use, low N2O and CH4, and eco-friendly. The objective of this study was to observe the effect of natural NI on the production potential of CH4 and N2O from paddy soil. The experiment in the laboratory was arranged in a factorial design (2 × 7 × 3 replication). The first factor was soil types (inceptisols and vertisols), and the second factor was natural NI (control, Cocos nucifera, Camellia sinensis, Coffea robusta, Curcuma domestica, Ageratum conyzoides). The results showed that the average CH4 production from the natural NI in the inceptisols and vertisols ranged 0,014-1,710 mg CH4 g soil-1 and 0,002-0,337 mg CH4 g soil-1, respectively. Application of natural NI reduced 32-69% CH4 production compare to control. Redox potential affected CH4 production. The chemical compound of the natural NI affected CH4 production in the soil. The application of coffee waste, coconut husk, tea waste, and Ageratum conyzoides reduced 60,71; 54,61; 64,83 dan 64,16% of N2O production in Inceptisols compare to control, respectively. Application of natural NI could contribute to save the environment because it decreased GHG production in paddy soil. Keywords: greenhouse gas, inceptisols, incubation experiment, natural nitrification inhibitors, vertisols

Abstract

The intercropping method is one way to maximize plants and soil's utilization in a dry land. This study aimed to determine the cultivation (cropping methods and fertilization) that could increase mungbean grain yield in dry land in the dry climate of East Sumba, East Nusa Tenggara Province. The experiment was conducted at dry land in a dry climate in Laipori Village, Pandawai District, East Sumba Regency in 2017. The experiment was laid out in a split-plot design with four replications. The main plot was a cropping pattern, namely (1) intercropping mungbean with maize. Mungbean plant spacing was 30 cm ´ 20 cm, two plants per hole, and maize plant spacing was (50 cm ´ 50 cm) ´ 120 cm, one plant/hole and (2) mungbean monoculture with a plant spacing of 40 cm ´ 10 cm, two plants/hole. The subplot was dosage and type of fertilizer, namely (1) 150 kg Phonska/ha, (2) 5000 kg cow manure/ha, and (3) 75 kg Phonska + 2500 kg cow manure/ha. The mungbean variety used was Vima 1, and the maize variety was Bima. The results showed that intercropping mungbean with maize could increase the yield of mungbean seeds yield by 0,28 t/ha (51,85%) and increase the mungbean biomass by 0,31 t/ha (22,30%) compared to the monoculture system. Different types and dosages of Phonska inorganic fertilizer and cow manure did not cause differences in the mungbean yield.

Abstract

This study aims to analyze the impact of the tariff and non-tariff policies implementation of the importing countries on the export performance of Indonesian processed tuna. A cross-sectional gravity model analysis was conducted to find out the impact of these policies on exports. The variables used include GDP per capita of the importing countries, population, economic distance, export prices, actual exchange rates, tariff policies, and non-tariff policies in the form of sanitary and phytosanitary (SPS) and technical barriers to trade (TBT). The estimation shows that the variables of GDP per capita of the importing countries, population, exchange rates, export prices, and SPS give a positive and significant effect on the trade of Indonesian processed tuna commodities. On the other hand, economic distance and TBT policy give a negative and significant impact on the volume of this particular commodity. Meanwhile, the tariff policy implementation also give a negative effect on the export volume, but it is not significant. Keywords: cross sectional gravity, export performance, non-tariffs, tariffs

Abstract

Pari Island has considerable natural resource potential, so that it has the potential to have socio-economic impacts on the local community if managed properly. The current management of Pari Island is indeed focused on the management of marine tourism, and this activity has been going on for a long time and has had a very significant impact on the economic sector in Pari Island. On the other hand, marine tourism activities in Pari Island are feared to have an impact on the ecological sector, so that to achieve sustainable management, good supervision and control is needed so that its potential is maintained. The purpose of this research is to see the status of socio-economic and ecological sustainability as a result of the development of marine tourism in Pari Island. The data were collected through in-depth interviews with the people of Pari Island, apart from that the data were also obtained from primary and secondary data related to socio-ecology. To assess the level of sustainability in each dimension, a Multidimensional Scaling (MDS) analysis was carried out, in order to obtain two dimensions that had a value below 75%, namely the institutional dimension which had a value of 27.3% (bad), and the infrastructure dimension which had a value. 73.3% (Enough). Meanwhile, the other 3 dimensions, such as the ecological, economic, and social dimensions, show that the value is in the continuous category, namely> 75% so that it is very supportive of the sustainability of marine tourism business management. Keywords: impact of marine tourism development, marine tourism, Pari Island, sustainable management

Abstract

Primary energy demand in Indonesia has rapidly increased, i.e., 43.33% between 2005 and 2016, while domestic energy supply failed to fulfill these needs leading to the reliance on the energy import. Meanwhile, a vast area of degraded land in Indonesia also created an opportunity for biofuel production, fulfilling energy demand, as well as restoring the land with environmental and socio-economic benefits. This paper provides an overview of identified potential and challenges associated with biofuel production from degraded land in Indonesia. Our preliminary findings highlighted that some biofuel species in Indonesia are suitable to grow in degraded land and potentially restore the land that may not be suitable for current agricultural production and/or reforestation. The initial finding also shows that culturally familiar species and stable markets are favorable terms of biofuel-species selection for the landowners. Supportive agricultural-extension services such as knowledge and technology for honey production can provide an added value in this concept, in addition to social (e.g., strengthening social solidarity and employment opportunities) and environmental (e.g., carbon storage, soil moisture, erosion control, and biodiversity) benefits. Meanwhile, to create this overall initiative to be successful, a supportive measure from the policymakers is needed. Further research on the capacity of biofuel species to restore degraded lands in different biophysical profiles. Analysis of biofuel production feedstocks and potential co-benefits viable business models, and the stable market is necessary to maximize benefit from biofuel production and to restore the degraded lands in Indonesia. Keywords: biofuel production, renewable energy, restoring

Abstract

The development of rice irrigated farming is constrained by the conversion of land agricultural to non-agricultural. Therefore, policy to develop upland rice production in dryland and rainfed lowland is increasingly being implemented. Efforts to expand the application of technological innovations as a lever of upland rice production have intensified by introducing new superior varieties of upland rice. This research aims to analyze farmers' attitudes and satisfaction levels with introducing upland rice to attributes based. The location of this research is in Tegalgiri Village, Nogosari District, Boyolali Regency. Primary data were obtained through a survey method of 35 farmers who planted the Rindang 1, Rindang 2, Inpago 10, and Inpago 12 varieties. Farmer attitudes were analyzed using the Fishbein Multi-attribute Model, while farmer satisfaction level was analyzed using the customer satisfaction index (CSI). The results are the attributes "production" and "resistance to pests and diseases" were agronomic performance which was the most essential and primary consideration for farmers in choosing varieties. Farmers have a positive attitude towards the four new superior varieties. The meaning is that farmers want to adopt and plant the new superior varieties of upland rice. Farmers' satisfaction levels are in the "satisfied" to "very satisfied" category of the four new superior varieties. Hopefully, the new superior upland rice varieties that were introduced can be a choice of varieties by farmers. Keywords: atributtes, farmer’s attitude, satisfaction level, upland rice, superior varieties
