Abstract

Program Pengabdian Masyarakat ITB Ahmad Dahlan Jakarta “Apotek Hidup” digagas sebagai respons terhadap rendahnya kesadaran warga Desa Bojong Renged akan potensi tanaman obat keluarga (TOGA) dan masih adanya lahan kosong yang belum dimanfaatkan. Tujuan kegiatan ini adalah meningkatkan pengetahuan dan kemandirian masyarakat dalam memanfaatkan TOGA sebagai sumber kesehatan alternatif, serta memanfaatkan lahan desa secara produktif. Metode pelaksanaan meliputi observasi awal terhadap kebutuhan dan minat masyarakat serta inventarisasi jenis tanaman obat, dilanjutkan dengan penanaman beragam TOGA (seperti kunyit, jahe, lengkuas, dan kencur) pada lahan yang telah disiapkan, serta serah terima pengelolaan taman Apotek Hidup kepada masyarakat setempat. Hasil menunjukkan bahwa program berhasil membangun akses langsung warga terhadap bahan obat herbal, memperkenalkan nilai dan manfaat TOGA, serta memfasilitasi upaya pengelolaan tanaman obat secara kolektif dan berkelanjutan. Kesimpulannya, Apotek Hidup di Desa Bojong Renged berpotensi menjadi model kesehatan komunitas yang mandiri dan berkelanjutan, mengurangi ketergantungan pada obat kimia, serta mengoptimalkan potensi lokal untuk mendukung kesehatan masyarakat desa.

Abstract

Studi ini bertujuan menganalisis dampak profitabilitas serta transparansi Corporate Social Responsibility (CSR) terhadap nilai entitas bisnis di sektor pertambangan yang tercatat di Bursa Efek Indonesia. Dalam kajian ini, indikator profitabilitas dievaluasi menggunakan Return on Equity (ROE), Sementara itu, pengungkapan CSR dinilai dengan menggunakan Indeks Penyampaian Laporan Keberlanjutan (SRDI). Rasio Tobin's Q digunakan sebagai cara untuk mengevaluasi nilai perusahaan dalam studi ini. Penelitian ini menerapkan metode kuantitatif, dengan menggunakan data sekunder yang diambil dari laporan keuangan sebagai bahan utama analisisnya dan laporan keberlanjutan perusahaan pertambangan papan utama pada periode 2021–2024. Studi ini memanfaatkan metode sampel purposive untuk memilih sampel yang tepat digunakan. Evaluasi dalam kajian ini diterapkan menggunakan regresi linier berganda, yang dilakukan setelah melewati tahap tes F dan tes T. Penelitian ini menunjukkan bahwa kemampuan mendapatkan keuntungan berdampak penting terhadap nilai perusahaan, sehingga menegaskan bahwa kemampuan dalam menghasilkan laba tetap menjadi aspek krusial yang diperhatikan oleh investor. Berbeda dengan profitabilitas, pengungkapan CSR tidak menunjukkan dampak yang bermakna pada nilai perusahaan. Penelitian ini menemukan bahwa informasi terkait aspek sosial dan lingkungan belum menjadi faktor dominan dalam keputusan pasar. Implikasi penelitian ini menegaskan pentingnya peningkatan kinerja keuangan yang berkelanjutan serta perlunya peningkatan kualitas dan relevansi pengungkapan CSR agar lebih bernilai informatif bagi investor serta stakeholder yang terlibat dalam pengambilan keputusan perusahaan.

Abstract

This study investigates the integration of the Apriori algorithm and time series forecasting within a Business Intelligence (BI) framework to optimize supply chain operations in the retail industry. The Apriori algorithm was utilized to identify significant purchasing patterns, enabling strategic decisions such as product bundling and cross-selling. Concurrently, time series forecasting, with an ARIMA model achieving a mean absolute percentage error (MAPE) of 8%, provided accurate demand predictions, supporting improved inventory management and resource allocation. The integration of these methods into a BI dashboard facilitated real-time monitoring and data-driven decisionmaking, leading to enhanced operational efficiency and reduced costs. While challenges such as data quality, computational resource demands, and user adaptability were observed, this research underscores the transformative potential of analytics in retail supply chain management. Future advancements in machine learning and IoT integration are recommended to further enhance system performance. Overall, this study demonstrates a pathway for retailers to achieve operational excellence and superior customer satisfaction through data-driven strategies.

Abstract

Indonesia's renewable energy penetration (12.3% in 2022) lags significantly behind 2030 targets (19-23%), with Cilegon City facing 1,167 unelectrified households and rising waste generation. This study assessed renewable energy development potential through LEAP-based electricity demand modeling (2023-2033) and technical-economic evaluation of solar photovoltaic and Refuse-Derived Fuel (RDF) systems. Meteorological and waste generation data informed engineering calculations and financial feasibility analysis. LEAP projections indicate residential electricity demand reaching 728.1 MWh per household by 2033, driven by 13.9% population growth. Off-grid solar PV systems demonstrate viability with Rp. 5,774/kWh levelized cost for unserved households. The proposed UPTD 3 Merak RDF facility shows strong economics: 22 tonnes/day capacity, 2-year payback, Rp. 12.5 billion NPV, and 3.01 benefit-cost ratio. Findings reveal that institutional rather than technical barriers impede deployment, highlighting needs for standardized subsidies, clarified jurisdictional frameworks, and municipal-utility partnerships. This research advances urban renewable energy planning by integrating bottom-up energy modeling with localized assessments, providing replicable frameworks for Indonesian cities pursuing energy transition and environmental sustainability goals.

Abstract

Overcoming climate change is crucial to ensure environmental sustainability. This research focuses on the development of chemically activated biochar (CAB) from mangrove litters that can be used for CO2 adsorption, which leads to reducing the impacts of climate change. The synthesisation of CAB was carried out via pyrolysis at 400℃ for 2 hours under nitrogen gas flow, followed by treatment using various activating agents (0.1 M of H2SO4, HCl, KOH, and NaOH) for 2 hours with a biochar-to-solution ratio of 1 g : 4 mL. The activation process was designed to enhance surface area, pore characteristics, and functional groups associated with CO2 adsorption performance. The observation on the characteristics of CAB using Scanning Electron Microscope and Energy Dispersive X-Ray (SEM-EDX), The Brunauer, Emmett, Teller and Barret-Joyner-Halenda (BET-BJH), Fourier Transform Infrared Spectroscopy (FTIR), CHN Analyser, and static batch CO2 adsorption tests shows the ability of CAB in capturing CO2 through several possible mechanism. Among the samples, KOH-activated biochar (B-KOH) exhibited the highest CO2 adsorption capacity, reaching 12.47 mmol CO2 g-1 biochar. This high performance is attributed to a potassium (K) composition of 9.74%, which effectively catalyzed the development of a microporous structure, resulting in a micropore volume of 5.927 x 10-3 cm3/g and an optimized average pore width of 1.543 nm. Furthermore, B-KOH maintained the highest O-H group area (1.533 a.u. x cm-1), enhancing its affinity for CO2 molecules. This research offers an innovative and practical solution to reduce greenhouse gases and is expected to have a significant impact, both locally and globally, in advancing sustainable development.

Abstract

Kota Semarang merupakan daerah yang rawan longsor, terutama daerah yang memiliki morfologi perbukitan. Melihat adanya kejadian longsor di beberapa wilayah Kota Semarang, maka diperlukan adanya asesmen agar dapat diantisipasi terjadinya bencana longsor. Penelitian ini bertujuan untuk mengetahui tingkat risiko kerentanan longsor dengan menggunakan Metode Anbalagan dan membandingkan dengan metode berdasarkan Permen PU No. 22 Tahun 2007 RI dan Slope Assessment System (SAS) Malaysia. Lokasi penelitian ini berada di lereng Gedung E10 Fakultas Teknik Universitas Negeri Semarang dengan dua slope pada area penelitian yaitu slope 1 dan 2. Hasil penelitian menunjukkan bahwa dengan metode Anbalagan, baik slope 1 dan 2 memperoleh skor 7,35 dengan tingkat kerawanan tinggi. Sedangkan berdasarkan pada Permen PU No. 22 Tahun 2007, slope 1 bernilai 2,44 tingkat kerawanan tinggi, slope 2 bernilai 2,16 tingkat kerawanan rendah. Melalui metode SAS, slope 1 memiliki nilai 0,95 dan slope 2 0,89 yang berarti keduanya memiliki tingkat kerawanan sangat tinggi. Berdasarkan berbagai metode pengaturan yang digunakan, pengaturan tersebut mendapatkan hasil yang cukup sama. Kata kunci: Anbalagan, Slope Assessment System, longsor, risiko kerawanan, Permen PU No. 22 Tahun 2007
