Abstract

Tangkai cabai termasuk limbah organik yang dihasilkan dari buah cabai. Tangkai buah cabai merah keriting (Capsicum annuum L.) mengandung berbagai senyawa metabolit sekunder seperti flavonoid, saponin, tanin, alkaloid, steroid dan fenolik yang berpotensi dimanfaatkan sebagai biolarvasida. Penelitian ini bertujuan untuk mengevaluasi efektivitas dan menentukan konsentrasi optimal ekstrak tangkai buah cabai merah keriting sebagai biolarvasida terhadap nyamuk Aedes aegypti. Ekstraksi menggunakan metode maserasi dengan pelarut etanol 96% didapatkan hasil 115,34 gram ekstrak dengan rendemen 11,534%. Proses penelitian ini menerapkan 5 kelompok perlakuan yang meliputi ekstrak tangkai buah cabai merah keriting dengan konsentrasi 1%, 3%, 5%, bubuk abate 1% untuk menjadi kontrol positif serta akuades untuk menjadi kontrol negatif, dengan setiap kelompok yang isinya 25 larva Aedes aegypti instar III dan IV dan dilakukan 4 kali proses yang mengulang. Hasil penelitian menunjukkan bahwa konsentrasi ekstrak 5% efektif sebagai larvasida dengan tingkat kematian mencapai 100%. Konsentrasi efektif (LC50) ekstrak tangkai buah cabai merah keriting (Capsicum annuum L.) yang dapat mematikan 50% larva nyamuk Aedes aegypti berada pada konsentrasi 1,718%. Pengujian membuktikan bahwa ekstrak tangkai buah cabai merah keriting efektif serta bersifat toksik dalam mematikan larva Aedes aegypti.

Abstract

Concerns about the shadow economy in Indonesia, estimated to have hurt GDP by around 25% per year. We try to calculate the effect of the components involved in tax revenue caused by the shadow economy because we projected it to hinder the growth of SMEs. It aimed the orientation at Indonesia. We got data coverage from official institutions of national and international related to variable limits. We observe the development in the period 2009-2020, which requires linear regression analysis methods and non-linear logistic regression. The results confirm that among the six hypotheses we propose, five hypotheses are acceptable, i.e. FDI has a significant effect on the share of SMEs, corruption perceptions and control of corruption have a significant effect on income and profit taxes, then it also has a significant effect on the shadow economy, and the shadow economy also has an effect significant to tax revenue. From other findings, only the share of SMEs has no significant effect on income and profit taxes. The added value of this empirical finding can reduce the weaknesses of previous studies that predominantly consider financial (tax) and economic dimensions so that variables such as SMEs, corruption control, and public perceptions of corruption.

Abstract

This study examines the government’s strategy to lessen reliance on capital-intensive manufacturing by strengthening agriculture, fisheries, and tourism as key sectors for boosting Local Own-Source Revenue and employment. The purpose of this study is to analyze the influence of the agricultural, fisheries, and tourism sectors on local own-source revenue and labor absorption in Bontang City. The study applies a quantitative causal-associative design using path analysis and relying on secondary data from the central statistics agency, the agriculture, fisheries, and tourism departments, and the regional financial management agency of Bontang City for the 2020–2024 period. The findings reveal that all three sectors have a positive and significant effect on local own-source revenue, with the tourism sector contributing the most, followed by the agricultural and fisheries sectors. Meanwhile, in terms of labor absorption, the agricultural sector has the most dominant influence compared to the other two sectors. The three sectors significantly contribute to the improvement of local own-source revenue and labor absorption. The study concludes that cross-sectoral synergy among labor-intensive sectors can strengthen local economic resilience and support sustainable regional economic growth. The implication is that local governments should enhance inter-agency collaboration, expand public investment, and formulate community-based economic empowerment policies rooted in local resources.

Abstract

The effectiveness of local tax collection has become a critical issue in regional fiscal sustainability, particularly amid increasing policy innovation and administrative transformation. This study aims to examine the influence of human resource capacity and policy innovation on the effectiveness of local tax collection in Bontang City and to analyze the interaction between these variables. A quantitative associative approach was employed using time series data from 2015–2024, including tax targets, realization data, and personnel records from the Regional Revenue Agency (Bapenda) of Bontang City. Data were analyzed using multiple linear regression with dummy variables and interaction terms through SPSS software. The findings reveal that human resource capacity does not significantly affect tax collection effectiveness, while policy innovation serves as the primary driver with a significant positive impact, indicating a structural shift in regional fiscal capacity. Moreover, a significant negative interaction effect was identified, suggesting that increasing personnel during innovation implementation reduces effectiveness due to transitional inefficiencies and administrative coordination burdens. The study concludes that regional tax administration has shifted from a labor-intensive toward a system-intensive model, emphasizing the need for automated data integration rather than workforce expansion.
