Published: January 2023

Abstract
Surabaya is one of the big cities in Indonesia which experiences population increase every year due to urbanization. Population growth can cause changes in land cover such as vegetation into built-up areas and an increase in energy consumption. Changes in land cover and increased in energy consumption resulted changes in the average temperature of urban areas. This change can disrupt health and thermal comfort. Temperature changes can be analyzed using remote sensing technology by observing land surface temperature (LST). LST observations can be carried out using Landsat-8 OLI/TIRS image. Landsat-8 has ability to record data continuously and has good resolution for thermal analysis. Image data processing was performed using Google Earth Engine (GEE) due to its advantage in computing big data without the need for good computer specifications. GEE can perform time series data calculations so that the results obtained will be more numerous and better The results showed that the temperature in the city of Surabaya tends to change every year with an average temperature of 31°C. The mean LST in Surabaya City decreased significantly in 2016 by 4°C but increased again in 2017 with an increase of 1.5°C. In the following years, the LST value in the city of Surabaya continued to increase with a constant increase every year. There were more than 20 districts which have temperatures above average. Those districts were located in the center of Surabaya city extending from north to south. In the other side, the districts in the west and east of Surabaya have temperatures below average. There were 17districts experienced a decrease in temperature and 14 districts experienced an increase in temperature. Benowo, Tandes, and Pakal districts were the areas that experienced an average temperature increase. Meanwhile, the districts that experienced the highest decrease were Tegalsari, Wonokromo, and Genteng

Determination of the Provincial Sea Area Boundary in Indonesia Archipelagic Regions using Cartometric Method
Authors: Yuwono  
Published: January 2023

Abstract
The marine areas management authority for provinces in Indonesia has so far been 12 miles from the coastline. The Draft Law of Republic of Indonesia concerning the Development Acceleration of Archipelagic Regions, which has been proposed since 2017 and is currently waiting for its ratification. It gives wider authority to provinces with archipelagic characteristics. The basis for determining the territorial sea boundaries of a province with archipelagic characteristics uses the principle of an archipelagic state, which is to draw the outermost line from the islands in the province. The method used to determine the boundaries of the area is cartometric method. Cartometric method is tracing/drawing boundary lines on work maps and measuring/calculation of points positions, distance, and area coverage using base maps other map as complementary. If this Draft Law is successfully ratified, then the area of marine management for the province with archipelagic characteristics will increase and there will be hope for increased welfare. The results of the study in 3 (provinces) with archipelagic characteristics, namely North Maluku Province, Maluku Province, and Riau Islands Province showed an increase in marine management area between 72.36% - 158.46%.

Authors: Lestari Mardiningsih Tri , Rohimatun  
Published: January 2023

Abstract
An excellent plant-based insecticide formula is effective against insect pests and must be safe against target plants and natural enemies of the problems. The study aimed to evaluate the persistence of cajuput and patchouli oil formulations under sun exposure to Nilaparvata lugens, their phytotoxicity on rice seedlings, and safety against predators Sycanus annnulicornis. The feed residue method was employed to conduct the persistence test. Phytotoxicity testing was carried out by spraying rice seedlings with oil formulations. Biosafety testing against predators was carried out using the dry-film contact method. Exposure to both oil preparations (patchouli oil: 0.02, 5.25; and 10.49% and cajuput oil: 0.02; 4.87, and 9.74%) under the sun for up to five days was still effective in causing mortality of N. lugens. Both oil formulas did not cause phytotoxicity in rice seedlings. Cajuput oil (concentrations of 4.87 and 9.74%) and patchouli oil (concentrations of 5.25 and 10.49%) were safe against nontarget insects, namely S. annulicornis.

The planting material, environmental conditions, and agricultural practices determine the oil palm performance. This research aimed to observe the performance of three oil palm varieties produced by IOPRI in Adolina Estate, Serdang Bedagai, North Sumatra. Adolina Estate is located on the eastern part and has a distinctive equatorial rainfall type with a sandy clay loam soil texture. The DyP Dumpy, DxP PPKS 540, and DxP Langkat varieties have been planted since 2010 in the same block with similar soil conditions and agricultural practices with total samples of 101, 147, and 124 trees, respectively. The growth parameters were height, length of rachis, petiole cross-section (PCS), and leaf area (LA), while the production parameters observed included the average bunch number, bunch weight, and yield. The results showed that DyP Dumpy had the slowest height growth with the most extended rachis length. DxP PPKS 540 has the highest average of PCS and LA, while the DxP Langkat had the fastest height growth and shortest rachis length. Furthermore, the DxP PPKS 540 variety produced the highest average yield, 24.85 tons ha−1, while DyP Dumpy and DxP Langkat have 23.19 tons ha−1 and 23.95 tons ha−1, respectively.

Published: January 2023

Abstract
Food crop commodities are strategic national agricultural commodities. In 2018, the Ministry of Agriculture has chosen Langkat Regency as a food crop agrarian area. In line with this, the direction of developing food crop commodities should be able to become a leading sector for increasing community welfare and income in Langkat Regency. This study aimed to analyze the types of leading food crop commodities and examine the influence of supporting factors for leading food crop commodities on farmers’ incomes, as well as strategic priorities for developing food crop leading commodities. This type of research was descriptive research using primary and secondary data. The analytical methods used were Location Quotient (LQ) analysis, multiple linear regression, and Analytical Hierarchy Process (AHP). The results demonstrated that the leading food crop commodity with the most significant LQ value was rice at 2.65, followed by maize at 1.49 and soybean at 1.12. The results showed that the influence of the availability of supporting factors for food commodities, such as procurement of inputs for production facilities, technology, infrastructure, marketing, farmer institutions, and extension services, had a significance value of less than 0.05. The t count or the f count was more than t table or f table, so each variable affected farmers’ income. The results of the AHP revealed that infrastructure development was the main priority chosen in the approaches for developing superior food crops with alternative strategies, including maintenance of irrigation networks (0.409), development of reservoirs (0.275), development of farm roads (0.196) and sluice maintenance (0.120).

Abstract
Zeolite is a hydrated microporous mineral of the aluminosilicate group, and the cation exchange capacity (CEC) of zeolite is high. Based on porous properties and high CEC, zeolite has the potential to be used as plant growth media (PGM). Zeoponic is a PGM made from zeolite mixed with compost and cocopeat added with macro and micro fertilizers suitable for plant growth. The goal of this research is to characterize the chemical and physical properties of zeoponic and several other PGM obtained from the market and to compare them for the growth of forestry plant seedlings and horticultural crops. This study was carried out from October 2021 to March 2022 in the greenhouse of the Department of Soil Science and Land Resources, Faculty of Agriculture, IPB University. The analysis of PGM was pH, electrical conductivity (EC), CEC, NO3-N, NH4-N, and bulk density. Parameters of plant growth were the height of plant, the leaves number, the leaf width and length, and the diameter of stem. The findings revealed that zeoponic has high CEC value than the other PGM, causing zeoponic to have low EC even though it contains high nutrients. With the chemical and physical properties mentioned above, the growth of mahogany plant seedlings in zeoponic is better than in other PGM. Likewise, the growth of horticultural crops grown in zeoponic is better than that of commercial media. This shows that zeoponic is a PGM suitable for growing forestry plant seedlings and horticultural crops.

AbstractNutrient input on calliandra (Calliandra calothyrsusMeiss.) seedlings is a necessity to increase productivity. The study has been carried out to evaluate the growth of calliandra seedlings from several populations in West Java after being treated with bio and chemical fertilizers. The treatment used 2 (two) types of biofertilizers, i.e., Rhizomax and PGPR, and chemical fertilizer from Cabriotop, as well as aqua dest as a control. Calliandra seeds were collected from 3 (three) populations of West Jawa, i.e., Sukabumi, Garut, and Cianjur. The findings showed a positive response to seedling growth after fertilization, either with bio or chemical fertilizer. Biofertilizer was more responsive than chemical in the variables of leaf number, stem segment number, shoot dry weight, diameter, and root dry weight. Seedlings from Garut mainly showed the best growth compared to the Sukabumi and Cianjur seedlings.
