Abstract

AbstractThe paper describes a landscape dynamic (Change Index-CI) of Ketapang and Kayong Utara Districs, West Kalimantan, in 1990-2018 and its correlation of peoples’ welfare condition and environmental condition change. Land-based investment has increased sharply in the past 20 years. This condition influences landscape dynamic and climate condition. CI is identified through spatial and temporal analysis by calculating human intervention level to land cover. Meanwhile, the condition of peoples’ welfare at sub-district level is measured from the district’s Human Development Index (HDI) which is analyzed from CI. In this analysis, the HDI is considered a dependent variable and CI level as the independent variable. Landscape environmental condition uses information on annual average temperature of landscape. The study applies simple regression method for the 2000, 2010 and 2018 HDIs with the CI of 1990-2000, 2000-2001 and 2010-2018 periods in 26 sub-districts. The results show that CI has positive correlation with the HDI of 0.086 regression coefficient value. It implies that there is significant correlation of the HDI and CI. The higher the CI value, the higher the HDI will increase. Thus, the regression result is the HDI = 60.103+0.086CI, with <0.05 value (significant). It means every growth by 1% at each sub-district, it will lead the rise of HDI by 0.086% at that sub-district. Meanwhile, the average of annual landscape temperature ascends along the growing CI. The temperature increases significantly by 0.95oC during 1990-2018 periods following the massive land-based investment. On the other hand, prior to the massive land-based investment during 1985-1990, the temperature increase was 0.32oC. Keywords: Change Index, Environmental Condition, Oil Palm, Spatial, Temperature, Welfare AbstrakJurnal ini menggambarkan dinamika lanskap (Change Index – CI) Kabupaten Ketapang dan Kabupaten Kayong Utara, Provinsi Kalimantan Barat pada periode 1990 – 2018 kaitannya dengan kesejahteraan masyarakat dan perubahan kondisi lingkungan. Investasi berbasis lahan mengalami peningkatan secara signifikan dalam 20 tahun terakhir. Kondisi ini mempengaruhi dinamika lanskap dan kondisi iklim. CI dapat diidentifikasi dengan memperhitungkan tekanan manusia terhadap tutupan lahan baik secara spasial dan temporal. Sementara itu, kondisi kesejahteraan masyarakat pada wilayah administrasi kecamatan dihitung dihitung dari Indeks Pembangunan Manusia (IPM) wilayah Kabupaten yang dihasilkan dari analisis menggunakan CI. Pada Analisis ini, IPM merupakan variabel terikat dan indek CI merupakan variabel bebas. Kondisi lingkungan landskap menggunakan informasi suhu rata-rata tahunan.Penelitian ini menggunakan metode regresi sederhana antara nilai IPM tahun 2000, 2010, dan 2018 dengan CI periode tahun 1990-2000, 2000-2001, dan 2010-2018 pada 26 wilayah kecamatan. Hasilnya menunjukkan korelasi positif dengan nilai koefisien regresi IPM sebesar 0.086. Ini berarti bahwa terdapat korelasi signifikan antara IPM dan CI. Kenaikan nilai CI akan meningkatkan nilai IPM. Sehingga, regresi yang dihasilkan adalah IPM = 60.103+0.086CI, dengan nilai <0.05 yang berarti bahwa korelasinya sangat signifikan. Hal ini berarti bahwa setiap kenaikan CI sebesar 1% pada setiap kecamatan, maka ini akan meningkatkan nilai IPM sebesar 0.086% pada kecamatan tersebut. Sementara itu, suhu rata-rata tahunan pada lanskap mengalami kenaikan selama adanya peningkatan CI. Suhu pada lanskap meningkat drastis sebesar 0.95oC selama periode 1990-2018, hal ini sejalan dengan investasi berbasis lahan mengalami peningkatan secara massif. Sementara itu, sebelum investasi berbasis lahan dilakukan secara massif pada periode 1985-1990, kenaikan suhu sebesar 0.31oCKata kunci: Change Index, Kelapa Sawit, Kesejahteraan, Kondisi lingkungan, Suhu, Spasial

Abstract

Aluminum waste recycling activities in Sumobito District, Jombang Regency, produce aluminum black dross that is classified as hazardous waste. Aluminum black dross dumped into the environment will become a potential hazard to human health and environmental quality. This study aimed to determine the soil condition at aluminum black dross landfills in Sumobito District. Soil quality was determined by comparing the concentration of heavy metals in the samples with the total concentration (TC) of heavy metal pollutants regulated by the Government Regulation of the Republic of Indonesia No. 22 of 2021. Soil samples were analyzed using X-ray fluorescence (XRF). The analysis of four landfill samples showed that all samples should be managed as hazardous waste. The analysis of soil samples carried out around the landfill area shows that three samples are managed as non-hazardous waste, and one soil sample must be managed as hazardous waste. This indicates that heavy metal infiltration of aluminum black dross from the landfill area into the soil area has occurred.

Abstract

Jumlah penduduk Indonesia yang selalu mengalami peningkatan setiap tahunnya menyebabkan kebutuhan akan lahan turut meningkat, sehingga berpotensi terjadinya alih fungsi lahan. Perubahan fungsi lahan dari pertanian ke non pertanian akan berdampak pada menurunnya kualitas lingkungan dan mengakibatkan terjadinya lahan kritis. Salah satu upaya yang dapat dilakukan untuk merehabilitasi lahan kritis adalah dengan melakukan rehabilitasi hutan dan lahan (RHL). Salah satu hasil dari RHL yang berada di Kabupaten Bogor, Jawa Barat adalah Hutan Organik Megamendung. Keberadaan hutan organik memberikan banyak manfaat, di antaranya sebagai tempat penyerapan karbon, daerah resapan air, hingga sumber keanekaragaman hayati. Berdasarkan hal tersebut tujuan dari penelitian ini, yaitu mengestimasi nilai guna ekonomi dari Hutan Organik Megamendung; mengestimasi nilai non-guna ekonomi dari Hutan Organik Megamendung; dan merumuskan alternatif strategi pengelolaan Hutan Organik Megamendung yang berkelanjutan. Metode yang digunakan dalam penelitian ini adalah pendekatan harga pasar, benefit transfer, dan PROMETHEE. Hasil penelitian menunjukkan nilai guna Hutan Organik Megamendung sebesar Rp1.589.532.870 per tahun; nilai non-guna Hutan Organik Megamendung sebesar Rp8.845.125 per tahun; dan alternatif pengelolaan yang dapat diprioritaskan adalah pengoptimalisasian lahan dengan sistem agroforestri.

Abstract

Peternak binaan pondok pesantren Al-Ittifaq merupakan salah satu peternak yang baru memulai usaha ternak domba dengan memperoleh dana bantuan dari program Balai Ternak BAZNAS. Peternak binaan dalam melakukan usaha ternaknya, alokasi input yang digunakan masih belum sesuai dengan input optimal. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi produksi usaha ternak domba potong, menganalisis efisiensi produksi usaha ternak domba potong, dan menganalisis pendapatan usaha ternak domba potong peternak binaan pondok pesantren Al-Ittifaq di Kabupaten Bandung. Penelitian ini menggunakan fungsi produksi Cobb-Douglas dengan estimasi Ordinary Least Square (OLS) untuk menganalisis faktor produksi yang memengaruhi produksi domba potong, metode Nilai Produk Marginal (NPM) untuk mengetahui efisiensi ekonomi, dan R/C ratio untuk mengetahui keuntungan usaha ternak domba potong. Hasil penelitian menunjukkan bahwa faktor-faktor yang berpengaruh signifikan terhadap produksi domba potong adalah bobot domba bakalan dan pakan hijauan ternak. Faktor produksi yang belum efisien pada usaha ternak domba potong yaitu bobot domba bakalan sehingga perlu untuk ditambah penggunaannya. Selanjutnya, faktor produksi yang tidak efisien yaitu pakan hijauan ternak sehingga perlu untuk dikurangi penggunaannya. Nilai R/C ratio usaha ternak domba potong pada seluruh kandang komunal peternak binaan masih menguntungkan meskipun penggunaan input optimal belum tercapai. The farmers assisted by pondok pesantren Al-Ittifaq are one of the farmers who have just started a sheep business by receiving financial assistance from the Balai Ternak BAZNAS program. In conducting their livestock business, the allocation of inputs used is still not in accordance with the optimal input. This study aims to analyze the factors that influence the production of sheep fattening business, analyze the production efficiency of sheep fattening business, and analyze the income of sheep fattening business of farmers assisted by pondok pesantren Al-Ittifaq in Bandung Regency. This study used the Cobb-Douglas production function with OLS estimation to analyze production factors affecting the production of sheep, NPM method to determine economic efficiency, and the R/C ratio to determine the profitability of the sheep fattening business. The results showed that the factors that significantly influenced the production of sheep are the weight of feeder sheep and forage. Production factors that have not been efficient in the business of sheep are the weight of feeder sheep so it is necessary to increase their use. Furthermore, inefficient production factors are forage so it is necessary to reduce its use. The R/C ratio value of sheep business in all communal pens of assisted farmers is still profitable even though the optimal use of inputs has not been achieved.

Abstract

Tourism development was a national priority in Indonesia, as outlined in the National Tourism Development Master Plan 2010–2025. Labuan Bajo, designated as one of the “New Bali” destinations, was prioritized for its rich marine biodiversity and high tourism potential. This study examined the key factors that influenced the sustainable development of the region’s marine-based tourism economy. Primary data were collected through Focus Group Discussions (FGDs) using the “World Café” method, involving stakeholders from various sectors. The data were analyzed using the Matrix of Cross Impact Multiplications Applied to a Classification (MICMAC), which mapped the interrelationships among variables. The analysis identified five primary driving factors: participation, infrastructure, regulation, human resource development, and training and education. Governance and conflict were categorized as relay variables, while coordination and information and communication technology were classified as output variables. Welfare, disparity, and income generation were considered autonomous variables. Infrastructure and participation demonstrated a strong indirect influence on income generation. These findings provided strategic insights to guide policymakers and stakeholders in developing integrated and sustainable tourism strategies for Labuan Bajo.
