Abstract

Abstract: The research aimed to analyse the climate type change and its effect on the weatland paddy production. The average precipation of area used a method of Thiessen Polygon. The temperature and air humidity used Dauglas HK.Lee’s classification. Meanwhile, Schmidth-Ferguson’ classification was used to observe the climate type change of the area and the climate change on the weatland paddy production was analysed through a regression multiple. The observation was conducted for 15 years in the first period (1983-1997) and for 15 years in the second period (1998-2012). The research results showed that the change of climate type in the area of Aceh Besar district had happened from the type A to the type B in the area of Saree and Kota Jantho subdistrict. Further, the climate change of type B to the type C also happened in Blang Bintang subdistrict. Saree had the average precipitation from 2.466 mm/year in the first period to 1.735 mm/year in the second period. Also, Blang Bintang subdistrict had the average precipitation from 3.857 mm/year to 1.393 mm/year, and Kota Jantho subdistrict had the precipitation from 4.431 mm/year to 1.917. The regression analysis showed that the climate did not have a clear influence on the weatland paddy productivity and the area the for live of wide harvested. Great Aceh District had implemented a development of agriculture for food plants which were not affected by the climate change structurally or non structurally. This can be seen from the fact that the Local Government had given a contribution to the society: such as giving new variety of plants in every planting season, organic fertilizer, drainage and reservoir building, opening a new weatland and agricultural extension workers. Although these contributions have not been implemented fully, they have given positive effect on the threat of food security in Great Aceh District for the last 30 years. This can be seen that the total of weatland paddy production in the last 15 years of the second period have got increased for 1.558.711 tons or 10.3 per cent and got decreased for 13.686 ha, so that the influence of climate change was not significant for two period examied. Abstrak: Penelitian ini bertujuan untuk menganalisis perubahan tipe iklim terhadap produksi padi sawah, rata-rata curah hujan wilayah menggunakan metode Poligon Thiessen, suhu dan kelembaban udara menggunakan penggolongan Dauglas HK. Lee. Sedangkan klasifikasi Schmidth-Ferguson digunakan untuk melihat perubahan tipe iklim wilayah, perubahan iklim terhadap produksi dilakukan analisis Regresi linier berganda. Pengamatan dilakukan pada periode 15 tahunan pertama (1983-1997) dan 15 periode 15 tahunan kedua (1998-2012). Hasil penelitian menunjukkan bahwa telah terjadi perubahan tipe iklim wilayah di Kabupaten Aceh Besar dari tipe A ke tipe B pada Kawasan Saree dan Kecamatan Kota Jantho. Selanjutnya perubahan tipe iklim B ke tipe C untuk Kecamatan Blang Bintang. Dengan rata-rata curah hujan Kawasan Saree 2.466 mm tahun-1 periode pertama menjadi 1.735 mm tahun-1 di periode kedua, Kecamatan Blang Bintang 3.857 mm/tahun menjadi 1.393 mm tahun dan Kecamatan Kota Jantho 4.431 mm tahun-1 menjadi 1.917 mm tahun-1. Analisis regresi menunjukkan bahwa perubahan iklim berpengaruh tidak nyata terhadap produktivitas padi sawah dan luas lahan gagal panen. Dikarenakan Kabupaten Aceh Besar telah menerapkan pembangunan pertanian tanaman pangan yang tahan terhadap perubahan iklim baik struktural maupun non struktural. Hal ini terlihat dari adanya bantuan Pemerintah daerah kepada masyarakat seperti: pemberian varietas-varietas baru setiap musim tanam, pupuk organik, pembagunan irigasi dan drainase, waduk, pembukaan lahan sawah baru serta tenaga penyuluh pertanian. Kendati demikian belum sepenuhnya terlaksanakan tetapi ini telah memberikan konstribusi terhadap ancaman ketahanan pangan di Kabupaten Aceh Besar selama 30 tahun terakhir yang terlihat dari jumlah produksi padi sawah 15 tahunan periode kedua terjadi peningkatan sebesar 1.558.711 ton atau 10.3 persen dan luas lahan gagal panen terjadi penurunan sebesar 13.686 ha, sehingga pengaruh perubahan iklim terabaikan selama dua periode tersebut.

Abstract

To raise large amounts of capital, companies usually conduct Initial Public Offerings (IPOs), which allows them to reach large numbers of potential investors. Prospectuses are used to inform the public of the nature and prospects of these offers. The prospectus contains financial and non-financial information such as Corporate Social Responsibility (CSR) spending. However, the level of disclosure is usually not uniform across companies. This study examines the nature and factors influencing CSR spendings disclosed by Indonesian companies in the prospectuses for the period 2012 - 2019. Research data was hand-collected and analyzed using descriptive statistics, Pearson correlations, and multiple regressions. The findings show that most companies disclose CSR efforts; fewer companies reveal the amount spent on CSR activities. Among companies disclosing CSR spending, more spending is allocated in the years leading to the IPO date (y) compared to previous years. Thus spending on y is relatively higher than y-1, follows by y-2 and y-3. CRS spending has a positive and significant relationship with company size. These findings are consistent across alternative model specifications. This study made an essential contribution to the CSR literature by providing Indonesia's first empirical evidence on the CSR expenditure in IPO prospectuses. DOI : https://doi.org/10.26905/jkdp.v25i2.5559

Assesments of Land Characteristics of Soybean at Bireuen DistrictABSTRACT. Bireuen district has been known as soybean production centre in Aceh Province. However, average yield obtained is still under national yield. This research aimed: (1) to find out a relationship between land suitability and soybean yield, (2) to evaluate a relationship between land characteristics and soybean yield, (3) to determinate the land characteristics as determinable factor for soybean yield. There were nine characteristics sites were used under soybean farming that have land heterogeneity among sites and homogeneity within sites: 4 under rice field and 5 under rainfed. Natures of land morphology was evaluated each sites, and then soil samples were taken for soil properties evaluation in laboratory. The parameter of land morphology properties, physical and chemical were then adjusted according to the need of land suitability for soybean. Level of land management and its yield done by farmers were also evaluated. Yield from each plot (2 x 3 m2) was at random determined. The land suitability class was determined by comparing the land characteristics/land quality with soybean growth specification. Criteria made by Agriculture Department was used as a guidance. Futhermore, in order to determine determinable land characteristics were arranged in multiple linear regression analyses, in which yield of soybean as a Y and land characteristics as a X. Research result showed that the class of land suitability established were in parallel with soybean yields measure under relatively good management plots. Of the land characteristics that can be used as determinable factor were slope, rainfall, texture, drainage, and nutrient storage (pH). A multiple linear regression equation was established for soybean yield as follow: Y= -1.133 – 0.018X1 + 0.001X2 – 0.001X3 + 0.009X4 + 19.555X5 + 0.025X6 + 0.781X7 – 0.019X8; R2= 0.98, where : X1 = slope, X2= soil susceptibility to erosion, X3= rainfall, X4= sand fraction, X5= N-total, X6= P-available, X7= K-exchange, X8= base saturation, and R2= determination coefficient.

Abstract: One of the area of priority for the slum area handling is Sabang City, Aceh province. The Slum areas in Sabang that will be reviewed are the village of Cot Bak U. The villages have obtained the handling project by Ministry of Pubic Work, Department of Development of Settlement Area, Aceh Province, conducted by 2016 through the construction of roads and Environmental drainage. This study aims to evaluate this project. The Research methods are quantitative and comparative approaches by calculating the data towards these two criteria after treatment and compare it with baseline data. Based on the results of the research can be concluded that the slums handling project towards these 2 (two) criteria does not give major change to value level of slums. For Cot Bak U village the point turn to 29 of 31 with a difference of 2 points. The results of this research indicated that the handling still needs to be implemented towards both slum areas. Moreover also need to conduct periodic evaluation of the value towards the slum area which has been assigned to find out the changes that occur as well as involving local communities in the maintenance of the quality of the neighborhoods, so that the expected value will be increased.Abstrak: Salah satu daerah yang mendapatkan prioritas untuk penangan area kumuh adalah Kota Sabang, Provinsi Aceh. Kawasan kumuh di Kota Sabang yang akan ditinjau adalah desa Cot Bak. Desa ini telah mendapatkan penanganan kumuh oleh Kementerian PU Satker Pengembangan Kawasan Permukiman Provinsi Aceh yang dilakukan pada tahun 2016 melalui pembangunan Jalan Lingkungan dan Drainase Lingkungan. Penelitian ini bertujuan untuk mengevaluasi pembangunan jalan dan drainase lingkungan. Metode penelitian dilakukan secara kuantitatif dan komparatif yaitu melalui perhitungan data terhadap 2 (dua) kriteria setelah penanganan dan perbandingannya dengan data baseline. Berdasarkan hasil penelitian dapat diketahui bahwa penanganan kawasan kumuh terhadap 2 (dua) kriteria kekumuhan yang telah dilaksanakan di kedua kawasan kumuh tersebut tidak memberikan perubahan yang besar terhadap nilai kekumuhan yaitu untuk kawasan Cot Bak U sebelum penanganan sebesar 31 menjadi 29 dengan selisih sebesar 2 point. Hasil penelitian ini menunjukkan bahwa masih perlu dilakukannya penanganan terhadap kedua kawasan kumuh ini. Salain itu juga perlu dilakukan evaluasi nilai kekumuhan secara berkala terhadap kawasan kumuh yang telah ditetapkan untuk mengetahui perubahan yang terjadi serta melibatkan masyarakat setempat dalam pemeliharaan kualitas permukiman, sehingga diharapkan nilai kekumuhan yang ada tidak mengalami penurunan namun mengalami peningkatan.

Abstract:Spatial planning of Langsa City is still required in order to realize clean city, neat and beautiful. Spatial planning can also improve performance of drainage channels so that flood and inundation do not occur. Gampong Teungoh village and Gampong Baru village is an area of development and entrance Langsa City from the east, that still occur floods and inundation of up to 0.3-0.5 m so that performance improvement of drainage channels is required. Drainage channel performance is good if the dimensions of channels enough to drain rainwater runoff.  Drainage performance was evaluated before and after spatial planning is done by comparing discharge or capacity of channel with discharge of flood design of rainwater runoff. Spatial planning is done by providing a green space area of 10 % of the land area of residential parcels, maintain the function of public green space that has been there, and make a parking lot out of the water absorptive material. After spatial planning is done, runoff coefficient decreased from 0.45-084 to 0.4-0.75 so that discharge of flood design of rainwater runoff also decreased. This is causes channel performance previously not good to be good. Then decreasing of this discharge also caused available of remaining land due to channel dimensions that smaller than before. In this remaining land was used as a green line that can reduce the value of the runoff coefficient and then reduce discharge of rainwater runoff, and ultimately may also impact the performance improvement of drainage channels.Keywords : spatial planning, performance, drainage channel, green space area, runoff coefficient, discharge storm water runoff.Abstrak:Penataan ruang Kota Langsa masih diperlukan demi mewujudkan kota yang bersih, rapi dan indah. Penataan ruang yang baik dapat juga meningkatkan kinerja saluran drainase sehingga banjir dan genangan tidak terjadi. Desa Gampong Teungoh dan Gampong Baru merupakan kawasan pengembangan dan kawasan entrance Kota Langsa dari arah Timur, yang . masih mengalami banjir dan genangan hingga mencapai 0,3-0,5 m sehingga diperlukan peningkatan kinerja saluran drainase agar banjir genangan tersebut tidak terjadi. Kinerja saluran drainase dikatakan baik jika dimensi saluran cukup untuk mengalirkan debit rencana limpasan air hujan. Kinerja saluran drainase dievaluasi sebelum dan sesudah penataan ruang dilakukan dengan membanding debit saluran dengan debit rencana. Penataan ruang dilakukan dengan menyediakan ruang terbuka hijau seluas 10% dari luas tanah persil rumah tinggal, tetap mempertahankan fungsi ruang terbuka hijau umum yang telah ada, dan membuat lahan parkir dari bahan serap air. Setelah penataan ruang, nilai koefisien aliran menurun dari 0,45-084 menjadi 0,4-0,75 sehingga debit rencana aliran limpasan air hujan juga menurun. Penurunan debit ini menyebabkan kinerja saluran yang sebelumnya tidak baik menjadi baik. Kemudian penurunan debit ini juga menyebabkan adanya sisa lahan akibat pengecilan dimensi saluran. Pada sisa lahan ini dijadikan jalur hijau yang dapat memperkecil nilai koefisien aliran dan kemudian memperkecil debit aliran limpasan air hujan, dan akhirnya dapat pula berdampak kepada peningkatan kinerja saluran drainase.
